- GM has a bulletin out stating this is a problem, they need to recall the vehicles with this thermostat and change the design, I suspect it's something in how it opens and closes, it's seems to operate differently than the ones I'm used to seeing. Let me know if you have tried this test.
I need to know what happened in on the same journey
Just replaced the thermostat in a 2017 XT5 with about 45000 miles on it. Outside of warranty and cost just under $1300 plus tax so about $1400. These are not easy to change. I hope it works for a long time!
👍🏼
Just been through hell getting ours fixed. Goodbye Chevy!!! Hello Toyota!!!
This happens to me but no code or check engine light, I just hear the fan blow on real loud and the temp gauge doesn’t work. Was going to get a sensor from auto parts store to change it, did that work for you?
Yes
Do you mind sharing where the temperature sensor is located on the engine? Please
Sorry, just seen this, lower left under the intake
Im getting code. And coolant temp doesn't read. Think its the temp sensor not thermostat. Cause i get heat
2019 blazer, bought used with 49000+/-miles, 2 days later shudder in shifting, goes to dealership they replace valve body and torque converter. 5 days later go visit son at college 700 miles round trip. Next day PO128 shows up steering assist disabled which leads to this thermostat/ sensor issue. Still got warranty but one service guy says drive it in - I said I’m 50 miles away if thermostat is stuck that won’t be good. Next day we call dealership and set up a tow that will fall under warranty…. Hope this doesn’t have to get uglyOnly 50000 miles . INSANE GM like this guy said DO YOUR PART,
Did you get everything figured out?
We did , but I got called to work and the wife had to take to dealership and sit and wait. Will get the invoice and info for you in a day or two. So far so good. Sorry for the delay.
My vehicle doing the same thing dealership telling me it’s not covered and I only have 43,000 miles!
My wife is having this same issue now I also have replaced the sensor but 2 weeks later trips out and reads 0 until the code is cleared
We has the same issue, it will reset and be fine but will slowly get worse, try to get it fixed before 60K, if you fight it, they will cover it.
@@JamesF406 where is the temp sensor located ?
@ceasar7821 Left side, under the intake next to thermostat, you can barely see it, grab a flashlight, it's down there👍
This is happening to my 2020 Chevy blazer now two with only 50,000 miles on it. Can I drive it for a little before I get it into the shop?
where is the temp sensor located
Left side under intake, hard to see
Hi James, can we speak via email or text the same problem just happened to my wife’s blazer and want to know the best way to handl this situation with gm or myself. Thanks let me know?
Sorry, did you get it fixed. 616.401.2591
Is there a recall for therstate
Should be
Power steering notification and check engine keeps coming on
Did you get it fixed?
Yes took it to Japanese family mechanic and havnt had any problems since
So we ended up taking the vehicle in the GM, after they told us the Thermostat was bad I argued the fact that I just put a brand new one in 3 months ago, GM agreed to pay for the replacement, the Thermostat still looked brand new, it was covered under warranty and has another 2k warranty on it. If your is doing this fight it, even if its over 60K, this is a known problem and GM knows it, otherwise it will cost you around 1k to have it fixed. I should of fought the first one, Im pretty sure they would of covered that one too.
Today 10.5.23 Problem still not fixed, ECM flashed, new thermostat ( well another new one) and they are still not sure, going to change out the temperature sensor, the same one I changed out a few months ago then when that doesn't fix it they are going to replace the ECM, not good...very frustrated but they are covering it all so far.
@boxstudio1506 So, this round they changed out the temp sensor, drove the vehicle for several 30 minutes trips and the code hasn't returned yet, we'll see.
@boxstudio1506 10.11.23 GM replaced the temp sensor I just installed a few months ago and so far the code has not returned, the temp sensor cost 10 bucks....it's cheaply made.
having same issue on my 2020, so is it the thermostat or the censor? Or do i replace both?
@denisdalyaev4275 it's most likely the sensor, but, you have to tear it all apart and the thermostat is right next to it, do them both.
i just need to see how to take it out and replace it you’re playing with me
Sorry, I will see if I can find a better video for you.
GM SUCKS!!
It does seem like stuff is cheaper these days.
