Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“I have been having problems with this vehicle from day one if checked cadlliac records, it will indicate as a brakes problem. 1 had 4 brake jobs done on the vehicle to find out later that it was not the brake, now they said it was the wheel beariing, which sound the same as when they told me brakes. The vehicle failed inspection in delaware because of the emmissions system ,at that time the vehicle was covered by warranty. I assume Cadillac fixed the problem to find out later they never replaced the catalytic converter. …”
NHTSA complaint #10191522, filed 2007-05, 60,000 miles“My 2003 Cadillac Deville with 7200 miles on the odometer over the past twelve months has experienced intermittent decelerating engine stall. This car is a crash waiting to happen, as it has stalled over 30 times. This car has high rolling resistance, so when it stalls, it comes to a sudden stop. The dealer says he can't duplicate the stall, and there are no computer error codes. I don't know what else to do. Get rid of the car? If I don't use the new car warranty, the dealer will replace parts in an attempt to fix the problem.”
