GMC Acadia Timing Chain Replacement P0018 P0019 Check Engine Light

Bought a 2012 GMC Acadia at Copart auto auction, was running rough and check engine light was on. Found trouble codes P0018 and P0019, removed valve cover and found loose timing chain. Replaced with timing chain kit. Runs good after repair engine light has not returned.

How much does it cost to fix it regularly? I have the same problem
