NHTSA complaint #10234121, filed 2008-07, 23,340 miles“It would be easier to list the things that are ok with this car.

The car's braking and steering capacity is extremely diminished. I've replaced a broken stabilizer control arm and now I'm told the front end needs to be rebuilt. This damage is a direct result of the continuing problem with the rotor warping. The check engine light is on more than off and its been in at least 10 times for this issue. …”
