A short circuit can cause dimming or failure of the rear turn signals and hazard lights, reducing the vehicle's visibility to other drivers and increasing the risk of a crash.

Water may enter the rear turn signal LED lights, allowing condensation to form on the circuit board, and causing a short circuit. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 108, "Lamps, Reflective Devices, and Associated Equipment."
