However, some owners have reported issues with their brake lights staying on after being shut off. In this article, we will look at the possible causes of this issue and provide steps to help you troubleshoot the problem.

Possible Causes

There are several potential causes for brake lights staying on after the car is shut off. The first possibility is a defective brake light switch. This switch controls the power to the brake lights and needs to be properly adjusted in order for them to turn off when the vehicle is shut off. Another possibility is a faulty connection or wiring between the switch and the light assembly itself. Finally, a malfunctioning stop lamp relay can also cause this issue. In all cases, it’s important to diagnose the exact cause before attempting any repairs or replacements.


The first step in diagnosing this problem is to check the fuse box under the hood of your G35 and make sure that all fuses related to your brake lights are in good condition and properly connected. If they appear to be okay, then you should move on to checking the wiring harnesses that connect your brake light switch to your light assembly. Make sure that all wires are securely connected and there are no frayed or broken wires in sight.

If everything looks okay with wiring connections, then you should check your stop lamp relay for any signs of malfunction or damage. This relay sends power from your vehicle’s battery to your brake lights when they are activated. If it is malfunctioning, then it could be causing your lights to stay on after being shut off.


If you have determined that one of these components is causing your brake lights to stay on after being shut off, then you will need to replace it with a new one before continuing with troubleshooting. Depending on which component needs replacing (fuse box, wiring harnesses or stop lamp relay), you may need professional help performing these repairs as they can be complicated if you don’t know what you’re doing

If you have determined that none of these components need replacing and everything appears to be functioning correctly, then there may be an issue with how your G35’s computer system interacts with its electrical system when shutting down the vehicle or starting it up again after shutting it down. In this case, it would be best for you take your car into an experienced mechanic who specializes in Infiniti vehicles so they can take a look at its computer system and determine whether there any malfunctions occurring during shutdowns or startups that could be causing this issue with your brake lights staying on post-shutdown period
