Inspect these first — most-reported on this model

• Engine (4 owner reports)Listen for knocks or ticking, check for leaks and blue/white exhaust smoke, and make sure it doesn't overheat. No check-engine light should be on.
• Suspension (1 owner report)Listen for clunks over bumps, check the car sits level, and look for uneven tire wear and worn shocks or struts.
• Service Brakes (1 owner report)Brakes should feel firm and quiet — no grinding, pulsing or pulling. Check for an ABS light and uneven pad/rotor wear.
• Structure (1 owner report)Inspect for rust, fresh undercoating, mismatched paint, uneven panel gaps and any sign of prior collision or frame repair.
• Power Train (1 owner report)Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
