What Owners Say

Exhaust manifold

"The exhaust pipe came loose in December 2024. It sounded as if there was no muffler. I paid GM dealer $669 to repair. I received a recent letter from GM stating they had this problem with the exhaust and to take it to the dealer to repair. They made a provision to compensate me for the prior repair I paid for and I am waiting for my payment now."
