NHTSA recall 20V143000
Electrical System, Exterior Lighting · Jaguar Land Rover North America, LLC
Details
What's wrong: Affects vehicles equipped with low line headlight assemblies. When towing a trailer with the trailer lights connected to the trailer socket and the vehicle's daytime running lights (drl) are on, the trailer lights may not function.
Why it matters: If the trailer lights are not working, following traffic won't be aware the vehicle is slowing down or stopping, increasing the risk of a crash.
The fix: Land rover will notify owners, and dealers will update the body control module software, free of charge. The recall began April 13, 2020.
