The transmission control module (TCM) can also experience issues. This module controls the transmission's shifting, and a malfunction can lead to erratic shifting behavior. If you notice any of these symptoms, it's essential to have your transmission inspected by a qualified mechanic. Diagnosing transmission problems can be tricky, so it's best to trust the professionals. Regular maintenance, including fluid changes and inspections, can go a long way in preventing transmission problems and keeping your Infiniti running smoothly.

Electrical System Woes

Electrical gremlins are a frustrating reality for many Nissan Infiniti 2000 model owners. The electrical system controls everything from the headlights to the power windows, and any problems here can significantly impact the car's functionality. One of the most common issues is with the battery and charging system. A weak battery or a faulty alternator can lead to starting problems and other electrical malfunctions.
