Example complaints

Selected from NHTSA records; personal details are removed. They are consumer reports, not findings.

“Vehile is an automatic. Vehicle jerks hard when lightly applying gas. This can be compared to starting in first gear (manual transmission) when not fully depressing the correct combination of gas and clutch. This happens when traveling from a dead stop at a traffic light or pulling into a parking space. Have had several near misses in hitting other vehicles.”

NHTSA complaint #10030924, filed 2003-08, 80 miles

“Dt: the contact states the airbag system failed twice in the past ten months. The onboard computer said srs warning did not drive at that time,. The vehicle had to be towed to the dealership. There was a code reset in the computer. This happened again, and they replaced a fuse box in the dashboard. The gas gauge has also gone out twice in one month. The dealership drained the gas and reset a computer code. When it happened again they had to replace a part in the gas tank and reset the computer code again. Both items were working correctly at this time.”
