Summary Verdict

The 2005 Jeep Grand Cherokee presents a mixed reliability profile. While its robust V8 engines and capable drivetrain are often praised, owners have reported notable issues, particularly with the 4.7L V8’s head gaskets and the electrical systems, including the TIPM and BCM. Transmission issues, especially with the torque converter on the automatic, are also a concern. The diesel engine, while offering good torque, can be susceptible to turbo and glow plug problems. Suspension components and common interior electrical faults like blower motor resistors are also areas to watch. Regular maintenance and prompt attention to early signs of trouble are crucial for managing the long-term reliability of this model.
