What can fail
The brake pedal stopper pad can wear down over time, causing the stop lamp switch plunger to stay extended when you release the brake pedal. This keeps your brake lights on continuously and may trigger unintended features like brake override, traction control warnings, or allow gear shifting without braking.
What the fix does
Your dealer will replace the brake pedal stopper pad to restore normal brake pedal operation and switch function.
