Inspect these first — most-reported on this model
- Steering (5 owner reports)Steering should be tight and centered — no play, clunks or wandering. Test at low and highway speed; listen for power-steering whine.
- 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.
- Power Train (4 owner reports)Drive through every gear: watch for slipping, hard or delayed shifts, and shudder. Check for transmission/driveline leaks and noises.
- Wheels (3 owner reports)Inspect wheels for bends, cracks and curb rash, and feel for vibration at highway speed.
- Vehicle Speed Control (2 owner reports)Test cruise control and throttle response, and watch for any hesitation or unintended acceleration.
- Electrical System (1 owner report)Test every electrical feature: windows, locks, infotainment, charging and all lights. Watch for flickering, dead accessories or warning lights.
