2008 Cadillac CTS 4dr Sedan w/Direct Injection (3.6L 6cyl 6A)
In less than 24 months of ownership car has spent over 6 weeks in the shop being repaired or awaiting parts for a repair. 2008 CTS has had issues with timing chains. Cadillac had to redisgn the part because of high failure rates according to the Cadillac representatives I have spoken too. In addition, I have had persistent keyfob issues, accelerator sensor failures, nicked wiring harness, etc. Cadillac has been less than sympathetic about the LEMON they sold me. The car has been in the shop so often, it probably knows the route by heart.
Reliability - GM has building millions of cars should know how to design timing chains and build reliable cars.
