Push Button Start Nissans – Won’t Start? Here’s the common fix.

Recently, my wife’s 2008 Nissan Altima wouldn’t start.  Press the brake, press the start button. Nothing. It didn’t even try to crank. I had changed the battery a few months earlier and felt confident that it wasn’t the issue.

A quick search online pointed towards a faulty brake switch. Pumping the brakes while pressing the start button would result in a start, but that’s no way to live especially considering the fact that this is the same switch that lights up the brake lights! No switch, no brake lights.

While I was at work, my wife stopped by the dealer and they confirmed the issue. I had called ahead and confirmed that they had a new switch in stock. Although I was able to price out cheaper replacements, we needed to get her back on the road quickly and safely. She picked up the new switch and headed home.

A quick way to confirm whether or not your starting woes are related to the switch is by pressing the brake and checking for brake lights. If the brake lights aren’t coming on or they are flickering, then you know you have a bad switch.

The part number of the switch listed for our Altima is 25320-AX00C

How easy it is to change the switch? It is about as easy as checking the oil.

Tools necessary:

  • None

For starters, it is probably not a bad idea to secure the vehicle by setting the parking brake or chocking the wheels.

Looking under the dash, look for the switch and disconnect the plug by squeezing the release and pulling the wire.

Once the wire is off, turn the switch counterclockwise until it pops out of the mount.

Reattach the plug. Test for brake lights and ability to start.

Pat yourself on the back for a job well done.
