Exclamation CAN A BAD BRAKE LIGHT SWITCH STOP CAR FROM STARTING?

Greetings all. My son has a 2012 Nissan Altima and he just found out that his brake light switch is bad and won't allow him to use push button start to start his car as the brake pedal doesn't move. So, I figured I would ask the question here just to find out if that's possible in our W222's. Please let me know. Thanks.

Yes, that is possible for any car. A failing brake pedal switch does not see the brake pedal as depressed when it actually is, which usually prevents ignition.

Thanks. But, what if you remove the button and insert the key instead?

If the car does not see your "foot being on the brake" it will not turnover regardless of the method you try.
