Land Rover Discovery Recall 20V143: Trailer lights may fail with daytime running lights on

What this recall means for you

Certain vehicles have a software issue in the Body Control Module. When a trailer is towed with its lights connected to the trailer socket and the vehicle's Daytime Running Lights are on, the trailer lights may not work.

If the trailer lights are not working, drivers behind you may not realize you are slowing down or stopping, which increases the risk of a crash.

The repair is free. Dealers will update the Body Control Module software at no charge, and Land Rover will notify owners. To check whether your vehicle is affected, enter your VIN at the NHTSA recall lookup or contact Land Rover customer service at 1-800-637-6837 (Land Rover recall number N428).
