What owners wrote

A few complaints as filed, shortened and with personal details removed. The first ones are among the most serious reports for this model year; the rest are typical.

During a frontal-impact accident, the driver airbag failed to deploy until after I hit the steering wheel. I then saw the passenger airbag deploy. Neither the seat belt nor the airbag stopped me from hitting the steering wheel causing chest wall contusions and muscle strains in chest and back. I'm still out of work due to the injuries. The car was totaled.

December 2003 CrashInjury

Dt*: the contact stated the vehicle's front end made a loud clanking noise and was taken to an independent mechanic who determined upon examination that both rotors needed to be replaced. The mechanic replaced the rotors. Then, the vehicle had problems with the rear end, and was taken to a local dealer who determined that the axle bearing was bad and that the rear wheels were bent. The dealer provided the vehicle with proper maintenance and brake service and repaired the fuel pump.

Reported at 54,000 miles, November 2006

Vehicle was purchased used approximately 2 years ago. On the approximate incident date, the clutch pedal failed to actuate the clutch after producing a loud noise. Inspection at a repair facility revealed failure in several clutch components and a metal fatigue failure in the clutch and brake pedal support bracket. I am filing this complaint on behalf of my daughter for the failed support bracket, which I have in my possession.
