Water may enter the rear turn signal LED lights, allowing condensation to form on the circuit board. That additional condensation may cause a short circuit.
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.
What to do
Dealers will replace both rear turn signal LED bulbs and replace the rear turn signal light assembly -- as necessary -- free of charge.
