What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Upon disassembly of the intake system of my car, it was discovered that the wiring harness had completely disintegrated - the insulation used on the wiring had become hard and brittle, causing multiple shorts and preventing it from being re-installed in the vehicle.
Sometimes the vehicle would stall completely but when the consumer removed the key and restarted it after several minutes there would be no repeat problem with the asr (acceleration skid control).
The consumer experienced 3 tire blow outs. (nar) approx 3 out of 4 tires have failed. Consumer is requesting a reimbursement for the replacement cost. *cb23.505
Seat control adjuster engaged spontaneously and moved completely forward while the vehicle (1992 mercedes benz, 500 sl) was travelling at 65 mph on beltway en route to bwi, pinning my wife against steering wheel, anfd forcing her to drive onto the fast lane shoulder.
The first tire was replaced within a month of purchase due to a bubble on the side. The tires were then only used for short city trips. When the tires were drive at highway speeds for two hours the thread seperated completely from the sidewalls..( dot number: tire size: 245-45z-17 )
