The carmaker has essentially found a defect with the switch that controls the brake lights. Due to the problem, the brake lights are kept from turning off. With such a problem, it could cause confusion and other motorists would not be able to make out if the Elantra was braking or not.
Hyundai has admitted that the brake pedal stopper pad wears out over a period of time and hence permits the brake light switch to remain depressed even if the brake pedal has been released. The concern first came to Hyundai’s notice in 2014, when a number of warranty claims began to flow in. And it kept increasing through 2015 and 2016 which urged Hyundai to issue this recall.
Hyundai has instructed its dealers in the US to contact customers and call for the affected cars to replace the brake pedal stopper pad at no cost.
