Driving down the road made my vehicle made a weird noise and lost all power. Took it to a dealership they said it was the timing chain. I spent 10k on a newer vehicle and this happens. Dealership it gonna be anywhere from $5,500-7,000 to fix it. I cam't afford to fix that. How is gm still making this motor with a timing chain issue and how is this year not on recall for this the years before were on recall for it. My vehicle justs sits on trailer. Jas been there for 2 monthes. Nothing like payin on a dead horse.
