- Drivetrain issues: Reports of clunking and squealing noises have been associated with certain model years.
- Dashboard cracks: A common and potentially expensive issue across many model years, especially in warmer climates.
- Timing belt and water pump: A crucial maintenance item. The timing belt should be replaced around every 90,000 miles, or the vehicle should have a documented history of this replacement.
