Toyota will be contacting the owners of certain 2020 Corolla vehicles because of an electrical problem that could cause the backup lights to fail.

The vehicles affected are equipped with a rear hatch that contains a wire harness for rear end electrical components. During the inspection process, damaged testing equipment may have caused the contact gaps of the wire harness connector to increase. Lower contact pressure inside the connector increases the chances of an oxide layer developing on the surface of certain terminals. Over time the electrical resistance could increase, resulting in loss of backup lamps. If the lamps do not illuminate when the vehicle is backing, there is an increased risk of a crash.

Those receiving notices can return to their dealerships to have the rear hatch wire harness replaced. Toyota’s numbers for this recall are 20TB07 and 20TA07 and the NHTSA campaign number is 20V-205.
