My wife passed in 2019. I have 2 other gm vehicles. Her enclave that I am driving now has a engine light on that refers to timing chain issues. There is no noise coming from the engine. Runs fine but don’t want to drive and ruin the whole engine. I read that this problem is covered on some vehicles. The vin number is 5galrbed0aj116693 and the mileage 118793. Please advise me on what steps gm will provide in order to correct this issue. I have a 2000 Z71 with over 200,000 miles and a chev 2013 1500 with 82,000 miles. Neither of these vehicles have timing chain issues. What happened in the enclave engine that it would fail this soon?
