• 2.5L inline-4
  • No Issues Found
• 4.0L inline-6
  • Cylinder Head Cracking: The cylinder head on the 4.0L engine can crack, which can lead to coolant leaks and engine overheating. Replacing the cylinder head is a major repair.
    • Estimated Cost to Fix: $2,000 - $3,000+
    • Recalls: None Found
  • Intake Manifold Gasket Failure: The intake manifold gasket on the 4.0L engine can fail, which can cause coolant leaks and engine overheating. Replacing the intake manifold gasket is a relatively minor repair.

• 4-speed Automatic
  • Transmission Failure: The 4-speed automatic transmission can fail prematurely, which can cause the vehicle to lose power. Replacing the transmission is a major repair.
