What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
$20k damage, including locked seat belts, which were in use at time of accident. My car has been in the body repair shop since noon on that day, feb. 6 and at present time it is at the second repair shop (cadillac dealer) awaiting seat belt repairs.
Stabilitrak light comes on that also causes the engine light to come on. The vehicle self-accelerate while in park and did again when in drive. Can not tell you how fast the Rpm accelerated due to panic that the vehicle was self-accelerating but it didn’t last long. Really quick and it went back to normal idling.
I was forced onto the shoulder of the interstate by a vehicle that came into my lane. As I went onto the shoulder, I hit a pothole (there were several), and it split my factory rim in half, damaging my tire, also.
The contact stated that the ABS warning light was illuminated. The vehicle was taken to an independent mechanic, who stated that the seat belt was the cause of the air bag warning light being illuminated. The vehicle was taken to another independent mechanic, who stated that the system needed to be reset.
gas leaks to the ground. I culd smell the fumes coming out of my home heater vents in My bedroom. I went to the garage and the fumes were very strong. I open both garage doors a nd the man door. then worried about a explosion,Gas water heater is in the garaaage. But I got into the car and drove it out to the driveway!
Catalytic converter cracked creating exhaust leak into engine compartment. The converter has been replaced 3 times in 75,000 miles for this defect. The latest replacement has now failed and is leaking exhaust necessitating a fourth replacement.
While driving 35 MPH, the rear passenger’s side tire experienced a blowout. The contact stated that prior to the failure, a mechanic informed her that all four of the tires appeared to have splits in the sidewalls of each of the tires. The contact believed that it was the cause of the tire failure.
20-inch aluminum alloys wheels are all bent. I purchased this vehicle from a dealer near Lansing, Michigan. Upon test driving there were 2 wheels low on air. The dealer inspected the wheels and assured me they were fine. Once I got home I took the car to a local dealer who confirmed that all 4 rims were bent.
