Engine
2.0L Turbocharged 4-Cylinder Engine
- Carbon Buildup on Intake Valves: Over time, carbon deposits can accumulate on the intake valves, reducing airflow and causing performance issues. Symptoms include rough idling, hesitation during acceleration, and reduced fuel efficiency. The solution is to remove the intake manifold and clean the valves, which can cost around $500 - $800+. Recall: None Found
Transmission
8-Speed Automatic Transmission
- Shifting Hesitations and Jerks: Some owners have reported experiencing hesitations or jerks while shifting gears. The cause could be a software issue or a faulty transmission solenoid. The solution typically involves updating the transmission software or replacing the solenoid, which can cost around $200 - $600+. Recall: None Found
Suspension
Front Lower Control Arm Bushings: The bushings in the lower control arms can wear out prematurely, causing clunking noises and poor handling. The solution is to replace the bushings, which can cost around $200 - $400+ per side. Recall: None Found
Rear Wheel Bearings: The wheel bearings in the rear can fail, causing a humming or growling noise. The solution is to replace the wheel bearings, which can cost around $300 - $500+ per side. Recall: None Found
Electrical
Battery Drain: Some owners have reported experiencing a battery drain that can lead to a dead battery. The cause could be a faulty alternator, a parasitic draw from an accessory, or a weak battery.
