Example complaints
Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.
“Since I bought the car, the odometer blinks and scrambles at various times, and when it is working the mileage is correct. Also, whenever I turn on my hazard lights, my anti-lock brake system light comes on and will stay on until the car has been off for awhile. Lastly, the vehicle has always made a grinding noise when I turn left, or accelerate uphill and I have had 3 motor mounts replaced and taken it to 3 dealers and 2 auto shops and nobody can seem to find a problem!”
NHTSA complaint #10121423, filed 2005-05, 11,000 miles“Rear brakes keep going out of adjustment. I have to get them readjusted almost every week. First started in febuary 2001. Since then especially in the last 1.5 - 2 yrs. Have to get adjustment done every week to two weeks. There has been several time most on fwys were I had to stop suddenly and the breaks did not catch. I kept going fwd. Luckily I was far enough back from vehicle in front of me that I did not hit them. During rainy days it's even worse.”
