I Have a 2010 GMC Acadia I had a new engine put in three years ago I get a check engine light on today with 46,000 miles on it time in chain is bad and it is out of warranty.

Gm wants $3,500 to put a new timing chain in. This is a brand new gm engine with only 46000 miles and the timing chain goes out again. Junk gm can’t make a 3.6 engine last longer then 46000 miles.

Knowing the maintenance history would help to understand if there was a problem with the engine, or if it somehow failed because of improper upkeep.

It was a new engine when it had 0 miles. It is a nicely used engine with 46000 miles. A timing chain failing at 46k is unusual but it does happen.
