Summary Verdict
The 2001 Jeep Grand Cherokee, while a capable and popular SUV, exhibits some common reliability concerns typical for its age and design. The 4.0L and 4.7L engines are known for potential head gasket issues and, in the case of the V8, valve seat recession. Automatic transmissions, particularly the 42RE, can suffer from torque converter and solenoid pack problems. Electrical gremlins, such as instrument cluster and window regulator failures, are also reported. Suspension components like ball joints and bushings are wear items that may require attention. Exterior rust can be a significant issue depending on climate. Overall, while not without its flaws, many of these issues are well-documented and repairable, making it a potentially good value if well-maintained or if these common repairs have been addressed.
