What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Due to sun light plastic housing of seatbelts they have cracked . Internal parts within seatbelts assemlby have failed due to poor manufacturing, causing a loss of protection.please provide further information.
Luckily, my brake failures have occurred close to home and there has been no loss of life or property due to my ownership of this car. Please look into this situation seriously. I pray that nobody dies from the defects in this system.
I opened the hood and the abs pump was running and billowing black smoke. Now there are essentially no brakes at all so the car is not driveable. The abs problem with the cadillac allante has become all too familiar with its owners who have spent many thousands of dollars in efforts to repair the defective system.
This can cause the car to lurch forward when you expect it to be slowing down... -- the parts associated are quite expensive - $350 for the accumulator, and $1600 for the sensor block.
