Summary Verdict

The 2000 Jeep Grand Cherokee, while offering strong performance and utility, is prone to specific mechanical and electrical issues. The 4.0L and 4.7L engines are susceptible to head gasket failures, and transmission issues can arise, particularly with the older 42RE. Suspension components like ball joints and tie rods are common wear items. Electrical gremlins, often stemming from the BCM or instrument cluster, can also be a concern. Rust is a significant factor to consider, especially in certain climates. Despite these potential problems, many Grand Cherokees have proven durable with proper maintenance, but buyers should be prepared for potential repairs, especially concerning the engine and electrical systems.
