What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
The headlights will sometimes jus turn off as were driving. The power steering hose busted an ruined power steering pump had to replace whole rack an pinion and pump. Nothing but problems with the vehicle an seems like its had one recall after another..
Ball joints need replaced. Should be a recall. Seems to be a common problem for this vehicle.
This event occurred aug.15, 2007 I filled up gas tank and light goes back to and stays on for several minutes, I don't if this dangerous but it can cause called a accident especially if the light come on and you driving with young children and they get upset and cause parents to have a crush.
