Mazda CX-50 trailer hitch wiring may come loose

NHTSA campaign 23V135000 · Reported 2023-03-01 · Mazda North American Operations

medium How serious is it? About this label

The CX-50 itself drives normally, but you should not tow anything until the wiring is repaired, because a trailer with no lights or brakes raises the risk of a crash.

What's wrong, in plain English

Some Mazda CX-50s were fitted with a Mazda accessory trailer hitch. The wiring harness that plugs into that hitch can come unplugged and get damaged. If it does, the lights and brakes on a trailer you are towing may stop working, so other drivers cannot see your turn or brake signals and the trailer cannot help slow you down. A dealer repairs the hitch wiring at no charge. Only vehicles with the accessory hitch are affected.

What you should do

1. Look up your VIN at nhtsa.gov/recalls to confirm your CX-50 is part of recall 5723B.
2. Schedule the free wiring repair with your Mazda dealer, or call Mazda at 1-800-222-5500 option 6.
3. Avoid towing until the repair is complete.
