Can Infiniti drivetrain maintenance help me save money?

What are signs my Infiniti drivetrain is damaged?

Noises toward the back of your Infiniti Q45, leaking fluid, trouble turning — these could all be signs of drivetrain damage you want to address. Take action before something more severe happens.

How often should I come in for Infiniti Q45 differential service?

Differential service frequency varies from car to car. Double check your owner’s manual and talk with a technician. We generally recommend getting your differential inspected and the differential fluid changed as a part of your regular vehicle maintenance routine since your vehicle cannot function without a differential.

Why is the malfunction indicator light (MIL) on in my Q45?

If your Q45 has its malfunction warning light (more commonly called the check engine light) illuminated, it could indicate engine troubles, problems with the transmission, electrical issues, malfunctioning sensors, connector problems, or misfire issues.

Can my Q45 malfunction warning light be reset at home?

While resetting a malfunction warning light at home is technically possible, doing so is not advisable. The check engine light is typically a sign of a problem in one of your Q45's systems, and simply resetting the light will not address the underlying issue. Instead, you should bring your vehicle to a reliable auto shop to have the underlying problem identified and fixed to help ensure the safety and reliability of your Q45.

How worried should I be about a drivetrain malfunction in my Q45?

Driving with a malfunctioning drivetrain can be dangerous and cause further damage to your car.

Does my Q45 transmission belong to the drivetrain system?

Yes, the drivetrain system in your Q45 includes the transmission. Other components in the drivetrain are the driveshaft, axles, and differential. Together, these components deliver power from the engine to the wheels to push your Q45 forward.

Care for your 1991 Infiniti Q45 to maintain its performance power. Follow Infiniti's recommendations for lubricating bearings/gears and checking/changing differential fluids to minimize repairs over time.
