Summary Verdict

The 2000 Ford Grand Marquis is a generally dependable vehicle, especially regarding its core powertrain. The 4.6L V8 engine, while robust, can be prone to intake manifold gasket leaks and spark plug issues, which are repairable but can be costly. The 4R70W transmission is also a known quantity, with torque converter and solenoid issues being the most common. Suspension components like ball joints can wear, and if equipped with air suspension, compressor failure is a possibility. Electrical gremlins, often related to the BCM or alternator, can also arise. Interior issues are typically minor, with blend door actuators and instrument clusters being the most frequent culprits. Overall, the Grand Marquis offers good value for its reliability, with most issues being addressable with proper maintenance and timely repairs.
