brake lights stay on

The brake pedal has a plastic striker plate on it. The plastic striker plate looks like a fat plastic thumb tack that fits in a hole on the brake pedal arm. After time, the plastic gets brittle and falls out. Then the brake light switch plunger goes right through the brake pedal hole and the lights stay on. Get a replacement for $3.49 plus tax from the dealer and put it in yourself. Push the seat all the way back, raise the steering wheel all the way up, get a flashlight, stand on your head under the dash, locate the hole and stick the rubber thing in the hole. Takes about five minutes (thirty seconds the second time you do it!). The hole is directly in front of the brake light switch plunger. Depress the plunger with your finger to double-check the lights go out. If the striker plate thing is good and the brake lights don't go out or they won't come on, the brake light switch is bad. To change the switch, disconnect the electrical connector, loosen the checknut with a 14mm wrench, and turn the switch all the way until it falls out of the mount hole. Installation is the reverse. If you count the turns of the old one coming out, you put the new one in the same amount of turns and you'll be pretty close on your alignment. Good luck.

Hello,

It sounds like the issue is a malfunctioning brake light switch.
The brake light switch is located under the brake pedal.
When the brake pedal gets depressed it pushes against the switch, which triggers the brake lights to come on.
Over time with normal wear and tear the switch can malfunction. It is probably shorted to the on position and that is why the brake light is staying on.
