If the brake light switch plunger does not retract as it should when the brake pedal is not being pressed, the brake lights may stay illuminated preventing accurate communication to following vehicles that the vehicle is slowing or stopping. Additionally, if the brake switch plunger is not retracted, then the transmission can be shifted out of PARK without depressing the brake pedal. Either condition increases the risk of a crash.
Hyundai Motor Company (Hyundai) is recalling certain 2013-2014 Elantra sedan, coupe and GT vehicles. The brake pedal stopper pad can deteriorate allowing the brake light switch plunger to remain extended when the brake pedal is released. This will allow the brake lights to remain illuminated continuously. It can also allow the shift lever to be moved without depressing the brake pedal, or activate the engine management brake pedal override feature.
