The Hyundai And Kia Engine Failures Explained.
HTML-код
- Опубликовано: 26 авг 2022
- In this video I'll go over why the Theta II engines that include the famous 2.4L and the 2.0L fail. These engines are in the Hyundai Sonata, Hyundai Santa Fe, Hyundai Genesis and the Hyundai Tucson but also in Kia Optima, Kia Forte and the Kia Sportage. I'll cover how they fail causing rod knock, seized engines, damaged cylinder walls, spun bearings, seized bearings, damaged timing chain, stretched timing chain, damaged piston rings, I'll also go over how you can diagnose and narrow down where the failure has taken place as well.

My Thete 2.0 died right at 145,000 miles. Rod knock followed by seized engine. Brought to the Kia dealership and they said "nothing we can do, looks like negligence", and they offered me $500 as a trade in. I found out about the class-action lawsuit, and the warranty was raised to 150,000. I went to a different dealer, brought the settlement paperwork with me.... and they dropped in a reman for free.
Was that a hybrid?
I had a 2010 Hyundai Accent and when I bought it the salesman told me to change the oil every 7-8,000 miles. I knew that was too many and instead did it every 4,000 miles. It ran great and I never had a problem with it during the entire time I owned it. I think these long oil change intervals recommended by the manufacturers are killing these engines.
Exactly, these car manufacturers want are cars to go to shit as soon as possible, so we buy new cars more frequently
Friend has a 2012 Sonata that caught on fire while her mechanic was driving it after a maintenance schedule.
Its long change intervals combined with both POOR quality engine oil (think bulk dums from Jiffy Lube) & also their poor quality oil filter made just for the oil change place. U cant buy such a filter that meets low specification at auto zone or walmart. AND then that same cheap owner uses poor quality regular unleaded that lacks the proper octane & detergent additives. The MFR rarely duplicates that scenario in their testing.
@@opinionsvary Well said! That’s why API created the “SP” specification to minimise LSPI and timing chain issues. Here in Europe, Tucsons come with the 1.6 DI Turbo engine which requires 0W-20 API SP oil. Their normal oil change states for 9300mi while the severe for 4600mi. Better stick with the severe though…
I just got a, 2023 Hyundai Sonata N-Line 2.5l turbo and I couldn't care less about engine problems as the warranty is, 10 year/100k mile warranty. Lol. So....I don't care if anything fails....I get it fixed/replaced for free. Ha also....I ALWAYS change the oil on a new car after the first 500 miles. Some engines just don't last as long as others. It happens....not a single engine and or car maker has an engine that has never had a issue or issues. Millions are sold and odds are, some will have issues, especially with some people driving em hard as all hell and not doing proper maintenance. Again, new hyundais now have a 10 year/100k mile powertrain warranty. So, couldn't careless about issues. Lol also, when buying a new hyundai, you can purchase a lifetime pwertrain warranty for around 2k.....so.....couldn't careless about issues.
You did good. My experience with no compression engines that have jumped time is to then pull all the cam caps and do a leakdown on all the cylinders. Your engine may have good valves. You might not have to pull the head. You are doing a timing chain/tensioner/water pump at this point no matter what. You know what you are doing. Great video.
WOW, I haven’t checked into this site in a while. I learned how to do my Elantra timing belt here. That was when there were only maybe 20,000 subs. Now it’s 1,000,000. Good work!
these step-by-step videos that you do are my favorites - please keep 'em coming!
will do thanks for watching.
As a tow truck driver from the auto club, I’ve picked up most cars with dead batteries, alternator issues and minor repairs needed, but kia and Hyundai are definitely the worst ones with blown engines.
Especially because people neglect to change the oil, or check fluid level 🫤
We hope to see you at Mollison OReilly’s!
Combine that with the way the owners drive. A lot feel they are driving a race car.
It's a manufacturing defect according to the video.
Hi Marco, good to see you here. The way I am buying cars that need work I'll be down there a bunch of times. Cheers
Well unfortunately these engines tend to burn through oil like crazy, I've had to replace oil 100 to 1000 miles after an oil change due to bad O rings, valve cover seals and oil pan gaskets...
We are lucky here in Australia. Our Kia and Hyundai cars come straight from Korea and we dont seem to have the problems your cars have in the USA. Also we change oil regularly here in OZ. I change my turbo Tucson`s oil twice a year with full synthetic oil...because I can. Never needed oil between services despite regular 2500km trips in hot weather.
I have missed your old mechanic videos, forgot how enjoyable they are.
Agreed. They’re almost therapeutic. :)
This is why I do all my own oil changes, it's at least done right.
Done right?

@@nexpro6118 That is one good warranty. Will probably never have to use it.
The underlying problem is severe engine oil dilution which eats away the rod bearings and wears the timing chain. In addition, these drivetrains cruise at very low rpm (1000rpm) which causes cylinder ovaling. If you do mostly short drives, change oil no longer than 4000 miles/6 months and downshift manually so you don't cruise at 1000 rpm.
Why does n engine at medium to high load at low RPM cause cylinder ovaling? Are the side loads very high on the piston under those conditions?
@@gregorymalchuk272 the tolerances have to be made so that the engine running a full load won't have expansion problems at full heat temps. The rings especially are gapped slightly looser to keep the ends from touching. It is the delicate balancing act you're trying to keep the expansion rates manageable with high heat but also dealing with the fact that fuel economy requires you to run at low RPMs and lower heat levels. This is why most performance manufacturers tell you to gas your direct injected or turbo engine all the way up to Red line now and then.
I like your videos as they have a mixture of technical details, real life costing and discussion of the realities of the weak points of certain car brands. (Also the possible opportunities for profit if a person learns how to repair a known problem related to a certain model) You are a very productive guy building your own shop, landscaping, buying and selling vehicles and making good how to videos all at the same time! Thanks
glad you like the videos, cheers.

Good to see you post again. Congrats on one million subs!
Congratulations on 1 million subs. Congratulations on completing the new garage. 🍾
You need to have a part 2. I would love to find out more.
Wow, as a 50-year-plus mechanic I can tell you that the oil in that engine was not changed at regular intervals, hence the brown cooked look on the internal parts which will cause internal failures. All these small engines run at higher rpm's and higher temps so change your oil. In the 60s-70s, Fram filters' slogan was"You can pay me now or pay me much more later".

A million subs! More videos, more money for you, to make more video's..... Glad to see someone still down to Earth making video's, and if anyone deserves to be able to quite their day job for YT $$, you're the one I think deserves it.
Hopefully you can get the issue rectified without buying a motor...congrats on the million!!
I'm a new subscriber. Congrats on your 1.1M fan club. I'm not a mechanic but I appreciated very much how you explained things regarding the dead Hyundai engine. You have an accent but I still think you are in the states. There is no grass, so you must be out west. I just ran it through KBB and you are a little low. It is worth between $8,900 - $11,000. I had to fix my earlier quote because you want the private party value not the trade-in.. I ran it with standard equip and I wasn't sure if it was a manual or automatic, I also listed it as "Excellent" condition. I am amazed at how perfect the wheels are.
P.S. There is one recall on it.
Informative, entertainment is saturated in this excellent presentation. Thank you for the video!💯
Already sub'd. A Toyota lover myself but interested in all Asian cars. Ur very good, looking forward to future videos on this. Good luck! 👍
Looking forward to part 2. Well done as always.

Great to have you back
Looking forward for part 2 and a bonus footage tour inside your shop.
Inside shop vid will be out soon, thanks for watching.
Our 2012 Sonata suffered rod bearing failure at around 85,000 miles. This occurred right before Hyundai officially started their recall/repair program for those engines, but they investigated briefly and replaced it free of charge anyway. No issues since--great reliable car.
@Ratz Patootie They're the biggest auto manufacturer globally, they're nowhere near going out of business lol.
@Ratz Patootie Maybe you know something I don't, but as far as I know the companies are still pretty financially healthy. The Sonata still sells like crazy, as do the small and midsize SUVs. I'm sure these recall issues cut down their margins but they still seem to move a lot of units.
@Ratz Patootie how'd it go? Dropped mine off for diagnostic today. Rod knock and limp mode at 90.8k miles. I think I'll have to get a rental out of pocket and pray kia reimbursed me in the meantime.
@Ratz Patootie good lord. It's my only car too and I have work and not a ton of money saved up for a rental. I sure hope it goes well. It's kind of sadistic for Kia to not have done a true recall on these vehicles. I can't describe how lucky I was to not have broken down in rush hour traffic when it would have been much more dangerous. That's like 90% of my drive time. It's a shame too because I really liked my optima ex until all of this.
@Ratz Patootie thanks Ratz. Can we just communicate here? I'll email you if you want I suppose but I get notifications when you reply to this thread. I'm going to call the dealership shortly and see what's going on. It should have been sitting there for about 24 hours now so hopefully I'll at least have a positive diag code by now. He said they have 4 cars in for engine replacement right now and if I was a positive diag then he'd order the engine same day and probably 3 week overall wait for me 🤞 I also need to figure out a rental today so I'll be calling Kia consumer affairs beforehand to see what they'll do for me
The best mechanic on YT, period! Glad you are back posting mechanical videos.
Not the best mechanic at all. I'd trust an Autozone parking lot mechanic over him. Bad timing doesn't cause a loss of compression, bad piston rings or other issues with the piston/cylinder walls do. Also as @BenzTech said the "small amount of compression" that he "felt" was definitely the cam lobes interacting with the lifters in the head.
You've obviously never watched South Main Autos channel.
Good to see you back
I don’t think any modern engine can go without proper maintenance any more. Particularly oil changes are critical. Hyundai did produce some bum engines though. I’ve got the 2.0 in my Kia and I do 5000 miles full synthetic oil changes. Interestingly, Kia sent out a recommendation for 3750 mile changes but didn’t specify for what type of oil. The factory service agent I called seemed to not know the difference.
One of the best automotive channels 👍👍👍👍
Thank you
Glad you think so!
Very informational videos. Appreciate your honest advice and suggestions. Good stuff.
Question:
If you were to buy or can suggest a "most reliable car/truck" to purchase.
New or Used?
What would it be? If there is such a model and motor and transmission.
Meaning I want to have it all maintained 100% and safe driving, good mpg and cost effective comfortable and where I can put on many miles per year. And just drive and drive.
I am tired of new vehicles with monthly payments, insurance and vehicles that need constant weekly detailing and cleaning all the time.
I just want 100% reliable transportation to and from each day and not worry about breakdowns and high repair costs.
I know there are a lot of variables out there and nothing is 100%
Just curious on your thoughts.
Thanks for your videos!
Glad to see your new content. Made my day. 🙏
A shame. This car design was very beautiful when it came out, and still is.
Love Hyundai. My Elantra has 375k miles on it and still rips. That said it seems between 2008 and 2018 they had major engine issues. I'm not going anywhere near their theta engine.
Yup I consider some of the Elantras very reliable cars. Problem is their Theta II engine is terrible.
What year is your car?
I had a 2017 Elantra with the shitty Atkinson cycle engine. I babied it and still needed a new engine at 12,000 yes 12K miles due to excessive piston slap traded it in for a Mazda at 45K and will never ever again invest in Hyundai

@@vurshawn1358 - well yeah, it’s only 8 months old 🤦♂️
Lots of varnish in there. My Ford Contour SVT has almost 300k, synthetic oil every 5000 miles. I changed the valve cover gasket at 275k and the engine looked new. It’s all maintenance, which most people don’t do.
Yep. Modern Synthetic/synthetic mix oils changed every 4/5k miles keeps internals looking new at 200k. Those cheap ass Korean engine’s definitely can’t handle that abuse😬!!!!
I'm changing my oil in my 2020 Tacoma 3.5L v6 every 5,000 to 6,000 Miles to in hopes that it will last and stay clean. With these new modern engines that have variable valve timing, small tolerances and small oil passages I feel like Toyota's 10,000 mile recommendation is too long to keep everything good.
@@steveo601 Are these Korean made, or from the American factory?
@@DrakeN-ow1imAmerican.
I had consistent maintenance and the records to back it up and I took care of my car and the engine is failing at 90k so I'm in the middle of oil consumption test to get a new engine. And my coworker said his niece has had to replace her engine twice. So absolute b*******

Clearly this guy knows his way around engines. Fun channel. Best car I ever had was a 1991 Hyundai that had a Mitsubishi engine and 5 speed.
I own a 2012 KIA Sorento, with the 2.4L engine. Recently it turned 100,000+ Miles. My son, who gave it to us as a present, was very loyal with the oil changes--I taught him that! It's burning oil (about 1-and-a-half to 2 quarts between changes, which I do every 6 months or 5,000 miles, whatever happens first.) Until the financial situation eases off, that's our ride, period!
Kia spec is 1 qt per 1000 miles. But regardless if you have good maintenance records there should be a engine recall to cover failyre

I bought a Kia Optima brand new and I did maintenance to the T for 10 years. When I sold it 4 days ago, it was immaculate, ran smoothly. A few hours later, the dude was so excited he drove it 120mph, and the engine froze 😂😂😂😂 kias and Hyundai’s are crap. I’m never buying another one.
The bottom end failures are likely from failed journal hardening and/or machining swarf left behind. The other things that go wrong are in line with what Toyota, Honda, VW-Audi, BMW, and almost everyone else has seen: too long oil change intervals and sludge sticking low tension piston rings. A lot of stuff mentioned in these comments is not based on facts from car repair shops. Kia and Hyundai are replacing engines with little investigation way past their 10 year powertrain warranty. The other brands are not nearly so cooperative much past warranty expiration that is much sooner.
Ex-Kia mechanic I talked to before buying a 1.6 CRDi said that if I changed the oil every 10-12k miles instead of the 20k in the book I'd be very unlucky to have a failure. He said that pretty much all the common faults on them were caused by oil sludge buildup, including timing chain issues, because they use hydraulic chain tensioners driven by oil pressure. He also suggested using a good flushing oil about every third or fourth service. I would guess that the chain driven gas engines would probably benefit from a similar routine, ie- more frequent changes and an occasional flush.
That sounds logical.
At Finland most car "guides" recomend oil change around 10-15k km, and some cars have maintenance only at 20-30k km. Interval
10k miles is 16k km, so even 10k miles exchange rate is kind of long compared to what is seen as standard at here.
Oil change is pretty cheap, so it is cheaper to do every 10k km/ 6-7k miles than replace thr engibe.
20k miles is 32k km, and if someone would sell car with that long oil change interval, most buyers would be really suspicious here, as it is way too long in our eyes
@@Haawser My kona N has a change interval of 8k miles and I am not going anywhere near that.I do not know why KIA gives such long extensions on oil changes.BTW a tech reported on the forum literally every car that caught fire had gone a long time without an oil change.Also In the united states we have 6 months of decently hot to very hot weather and hot weather and turbo cars--esepcially in stop and go traffic destroy oil.
We had a 2015 Kia Sorento with the gdi 4cyl my wife always had it maintained by the Kia dealership every 4k and at 70hk it siezed up, Kia tried to play that lack of maintenance and charge us 7k for the motor after research and they opened our maintained motor that had no sludge they covered the whole motor. It is 100% a design flaw. I recently did some HVAC maintenance at our local KIA dealership and there still having engines fail with low miles now the V6 engines are have an overheating issue. Yes they are covering the failures and yes the cars are extremely nice for what you pay. But they need to redesign the engines. I will say the gdi turbo 4cyl is usually lack of maintenance
@@rollandsaxton Had a friend of mines just had the engine replaced last year on his 2014 Sonata 2.4, no turbo. Engine light was flashing and code was for knock sensor.

The sad thing with these engines is that they were originally making the 3.3L V6 Lamda II engines and the Theta engines at the Montgomery engine shop, for use in Sonata, Sorento, Santa Fe, etc. But they had enough issues with the 3.3L they decided nope we are gonna stop making that V6 and focus entirely on the Theta 2. And then those sucked worse. The Montgomery engine plant was just a disaster house, not entirely all their fault. The designs were bad. I'm on my third vehicle with a Lamda II V6 and I actually like this engine. Shrug.

Which auction did u get this from , all the auctions I went to in Los Angeles county have junk cars that go for 2500$
Probably ten years ago, Hyundai/Kia came out with a TSB regarding aftermarket oil filters. It said some aftermarket spin-on oil filters would not flow oil properly when used on Hyundai/Kia engines. This would result in oil starvation issues with the engine. It was recommended that Hyundai/Kia oil filters only be used. I know this was a big issue for many years and Hyundai/Kia did little to inform customers about this issue.
The engines are junk. Oil filters didn't cause the problems.
Common spin-on oil filters have an internal bypass valve in case the paper element gets clogged. If the element was clogged with metallic bits, then the bypass will open and oil with metallic bits will flow throughout the entire engine, and of course that is bad for the rod bearings, which have a very tight clearance and require clean oil to flow.
As a kia master mechanic for 8+ years I have never seen a timing chain issue. Please show us the bottom end rebuild as we never do that at the shop. Only short blocks

This is good news because I have ordered a I20n as long as I do the oil change every 10 Thousand clicks.
@@ljp1942 I would change your oil every 5000 miles to be safe that's what I currently do and I've had no problems.
@@sprograt Hyundai makes great performance cars these days.
@@ljp1942 I've had my I30N since Sept 2018 and I love it and that's me coming from a 2016 Golf R that cost me a lot in repairs other than servicing, fuel, and insurance the Hyundai has cost me nothing, the I30N cost me £26000 new if I sold it today I would get £24000.
I just got a, 2023 Hyundai Sonata N-Line 2.5l turbo and I couldn't care less about engine problems as the warranty is, 10 year/100k mile warranty. Lol. So....I don't care if anything fails....I get it fixed/replaced for free. Ha also....I ALWAYS change the oil on a new car after the first 500 miles. Some engines just don't last as long as others. It happens....not a single engine and or car maker has an engine that has never had a issue or issues. Millions are sold and odds are, some will have issues, especially with some people driving em hard as all hell and not doing proper maintenance. Again, new hyundais now have a 10 year/100k mile powertrain warranty. So, couldn't careless about issues. Lol also, when buying a new hyundai, you can purchase a lifetime pwertrain warranty for around 2k.....so.....couldn't careless about issues.
I just turbo’d an old 99 Elantra. I took it out on its first little rip only on 5psi and broke the transmission 😂
Ive got another one on the way. Hopefully I have better luck with this transmission.
I have a Santa Fe with the 3.3 V6 Lambda. It has 160,000 with no issues. I have heard things about the 2.0 though. Keep us posted.
I came across a 2012 sonata at a job I was doing and I asked the customer what happened to it and he said it just died on him while driving it.he said his mechanic told him his engine blew out. I kinda expected fluids and didn’t see any oil coolant mixture . The car was in good condition interior and exterior so I asked how much and I believe it had 135,000 miles , he said $1,000 but after researching those engines had recalls and was past warranty, so I passed on it
My 2013 Kia Optima 2 lt Turbo had a recall and they put a new computer chip in at about 190,000 km. They guaranteed me that if I had any engine issues it would be covered. Sure enough about 20k later the engine went out in a very rural area in the mountains of BC. I called the nearest dealer and they advised me I was
"Covered". In the end they paid $500 for vehicle recovery, supplied me with a U Drive and put in a factory new engine... all at no charge. I use full synthetic oil and change at about 5000 km as Turbo oil lines can clog with dirty oil. I now have
220,000 km and it runs great. I will watch Turbo as it's original .

So were you able to replace the timing chain and get it running or did you have to tear into the engine?
Thank You for this VIDEO!!
Not all of them were bad. I work with a lady who has a Sportage with 250k miles zero problems
How come i had a forte that had 200K on it before i sold it, and was still running great, and i presently have 2 Kia Borrego with over 250K on each of them, one of them i bought 11 years ago, and there are still running like a champ and don't burn any oil, they have been Toyota like reliable.
Borregos are built like tanks and your Forte was probably well maintained.
Which is the better build quality & more reliable engine/drivetrain, with the less maintenance and service costs over life of engine/drivetrain , between the naturally aspirated petrol engines of the current 2022 4 cylinder 2.5l/8spd auto in Hyundai Tucson, the 2.5l/6spd auto in Mazda CX-5, the 2.5l/8spd auto in the Toyota RAV4 awd's??. Stuck on , which one is best to go with, coz they're all good & bad in different ways. Seems like the 2050 models will be coming out before I can truely decide on which one😂. Any thoughts or suggestions??.
I saw this on a 2018, engine started with a knock. Then eventually gave out and dropped the piston.
Over the last 12 years all our cars were Hyundai's. IX35, Grand i10, i10, Atoz. Secret is change the oil at 5000 miles. Air filters and cabin filters at 10000 miles is fine. Never had a problem with any of them. They are all going strong. Ee also have a 1993 Camry. Gets oil changed every 3000 miles.
19 years and 200,000 miles and still running fine!
kindly, what the name of the angle wrench you used
My 2005 Hyundai Tuscon GLS has 143,000 miles on it and I have never had engine problems with it. Still drives like new.
Was this just a problem in the US market? Engine assembly in the US? Haven't heard anything about this or problems in the New Zealand market and I'm in the motor trade
149K miles on my 2011 2.4L... going strong and smooth. 3500 miles OCI since new on the dealer's advice (I'm in a what is considered "extreme conditions" area). But I doubt it will remain this way to 200K miles like my 2000 4cyl Accord did (let it go when the transmission started acting up... but the engine was perfect)
Yep. Just change the oil often and they'll be fine. I'm not a fan of these 15k mile or once a year oil change intervals. They recommend that in my Mercedes Benz but I still change the oil every 5k miles versus that 15k crap.
@JaretKade Agreed I run a catch can on our 2020 Tucson 37,000 miles still runs better than new also absolutely no oil burn off . The dealership uses 5w-20 Quaker state,I change myself now and use 5w-20 Pennzoil platinum as it was the only one Available it is a world of difference from the Quaker state especially in this Florida heat. 4,000 miles interval . That Quaker state looked like water at 5,000 miles still protecting but didn’t trust it, so far I’ve gone I think 2,500 miles on the pennzoil and it’s still holding up nicely with mostly city driving.
One question. what mileage is considered ‘normal’ for a passenger car in your area? here in korea if the car reached 125k miles, we deemed it as almost the end of the car’s lifespan.
@@powershin12 That’s just getting started in the US. Because North America in general is so large it’s not uncommon to acquire high mileage on a car/truck pretty fast especially if they drive for work or live in a rural area. I work at a dealership and we regularly take cars on trade with 250k or more miles on it and most run nicely if maintained.
@@IKhanNot Wow that is almost a double!
Just bought a 2011 Genesis Coupe with the 2.0 in July, well maintained with low mileage. Runs great... fingers crossed it stays that way!
@@ACommenterOnRUclips how does it have so low miles?
dude, you're awesome! after watching you (and others) i started replacing my engine oil every 5k and also learned how to do an ATF exchange and did one for my vehicle and my girl's vehicle!

Welcome to the DIY/ semi pro mechanic world. Soon you'll be doing brakes, suspension and all that jazz. These guys are great for plenty of advice about certain cars and general ideas.
@@azhule4041 appreciate it! i admit, i'm wary about doing my own brakes, even though i think i can. brakes are the 1rst & primary defense in safety. i guess if i can do my own trans fluid, i can handle brakes too. last couple of years i've been obsessed w/ buying tools. can't get enough.
@@mattsmith6828 harbor freight will be good to you, as will home depot and lowes. All ya need is a chris fix video, some sockets, a torque wrench, and a bit of patience. I believe in ya, I was there once. Nervous after my first oil change thinking I didn't tighten up the drain plug enough.
what are your thoughts on the 2022 Kia Sorento diesel?
I believe these trouble started soon after Hyundai decided they wanted to make their cars more like the Germans. I guess they really did
lol
Are they really THAT bad?

I had a 2014 Hyundai sonata and the engine did what he said at around 90 thousand miles.hyundai did replace that engine at no cost to me.plus, they payed for a rental car for me while they where working on it. I am now driving a 2013 Hyundai sonata that has almost the same kind of engine and so far,the only thing I had to do to it was put new spark plugs on it and at around 160 thousand miles I started haveing to add a little more oil to it in between oil changes but the mechanic a who knew the reason why it started useing more oil around 160 thousand miles said that he could fix it but it would just be cheaper to keep adding oil in between oil changes.I try to get oil changes at about every 3 or 4 thousand miles and so far,I had not had the same problem with the 2013 Hyundai sonata that I had with the 2014 sonata,but I'm also more diligent now about getting oil changes then I use to be.Also,I owned a Ford focus one time were the pistons locked up and caused engine failure.

@@nexpro6118 Not sure about the 2023 sonata engine,but my husbands 2020 hyundai Sonata 2.5 liter engine uses excessive oil.My husband has to add half a quart every two weeks.If I could make a suggestion,I would keep a constant check on oil and other fluids in your car but your right when you say that most cars have something wrong with them when they come off of the assembly line and that's with most all car manufacturing companys.personally,I think that the reason why car manufacturers are haveing so much trouble with their engines is because the government is always wanting them to change something to make the car more fuil efficient or to make it more "environmentally friendly" and sometimes that may cause car manufactures to have to compromise on quality and safety of cars and car engines.
2011 Kia Forte with theta II engine has 120k miles, every time it cold starts or idles while driving sounds like it has a rod knock or bearing noise from the engine. Is that common for that year?
We did have a string 11-13 Theta engines in the first gen Fortes fail all at once so yes, it is still common. Now there is also a variable intake runner valve that causes a similar sound. Look into it. It was covered by warranty.
Are these motors those made in the USA or those made elsewhere?
I have a 2007 sonata with a 3.3 v6 and a 2008 sonata with a 2.4 v4. 07 has 190k and the 08 has 230k. Both cars have had zero engine issues, very minor other issues, and the engines just purr on the highway. No transmission issues either. Proper maintenance, that's it.
I also have a 2007 Sonata, 2.4l auto. It developed a rod knock on #2. Dropped the pan and oil pump/balancer. Removed all con rod bearings, cleaned, scraped and flushed out all oil passages, polished and checked crank, installed new con rod bearings. Checked all main bearings. Buttoned it all up. Have added almost 100,000kms since, still strong. Total cost - $284.00.
V6 are awesome I’ve seen many at 350 k with no oil changes 😂
We have a Kia 2005 3.3 L engine. Lacking power and sluggish.
We were told to replace all the coil packs. Did nothing.
Mechanic said the valve cover gasket is leaking oil down in around the spark plugs.
I own a 2010 forte sx with the theta 2.4L. It was hands-down a build quality issue. Then when you mix in lack of maintenance 🤦♂️…I am technically on the 3rd engine during my ownership. First one was in the car at 175k, drove it home with a bottom end knock. 2nd engine had a bad wrist pin and luckily was warrantied out. The current engine has been good but was low mileage at 63k out of a totaled koup. These engines are poop. And they’re in so many vehicles….it’s a damn shame

I have a 2.4 L Hyundai Tucson. There is a recall on the engine in mine (2019) that suspected there was an oiling issue during crankshaft milling at the factory. I do mostly highway driving and the dealership mechanic told me that if there were a problem, I probably would not see it...stop and go ?...perhaps.
I had a 2006 Sonata. Best car i ever had. Not a single problem in the 10 years i drove it.

I ALWAYS change my oil on a new car just after the first 500 miles. Also, upgrading a engines oil pump can help with lubrication pressure at cold starts and at engine idle times. The good 'ol "hemi tick" sound can be fixed with putting the SRT engines oil pump on the engine. Pressure is higher now at cold start and at idle times which also protects the lifters and cam.
1 million. Congratulations!
thank you
Before checking compression, surely a camera down the plug holes first?
I got a 2018 in December. It has less than 7k miles on it and has been back twice for dropping to limp mode from a knock sensor code. That's once before they changed the sensor and once after. The car can't handle rpm load when passing or merging onto the highway. Both times the car dropped to 40mph almost immediately, almost causing pileups. DO NOT BUY A THETA II EQUIPED HYUNDAI OR KIA.
3.3 v6 2008 Santa Fe. 357,000 miles and still running when I sold it
The only problem was the recall that they never could/would fix where oil leaked from the valve cover into the alternator
I would seal it every month or do and add oil and it kept on running !
Same problem. I have a 2008 with 145k. Is there any way to stop that pesky leak? How many times did they replace it for you for free? I have had it done 3 times in 25k miles.....I hate it. Maybe I should get all new valve covers?
@@pattycheeze I paid for the first one before the recall, they fixed it twice for free, I gave up after that and would put the red gasket in a tube on it on the outside. That would last about 6 months to a year.

@@citypicker4449 thanks for the advice man! I will look into it. Sucks that a good car has that problem. I'm thinking I should get new valve covers. Maybe the cover is damaged from time and a new one would keep the seal longer.
Nice work! Sorry I missed your party!
My 2010 Sonata with the 2.4 engine has been a great car. The one thing to be carefull with is the oil filler cap is located in a recess. Sand and road debris collects in the recess. I always blow the cap off with compressed air before opening. If you don't do this the sand will fall onto the #1 cylinder valves and timing chain.
