Mazda CX-5 Recall 17V744: Trailer Wiring Can Rub Exhaust, Causing Lights to Fail

NHTSA campaign 17V744, reported November 21, 2017, 1,076 vehicles potentially affected.

What this recall means for you

A trailer hitch wiring harness may be routed too close to the exhaust muffler, with too little clearance between the two. Over time, the harness can contact the hot muffler and become damaged. This can make the trailer lights stop working, which raises the risk of a crash because other drivers may not see your trailer or your intentions.

Owners will be notified by mail. Authorized Mazda dealers will reroute the trailer hitch harness away from the muffler and replace the harness if it has already been damaged, at no cost to you. The recall is expected to begin January 20, 2018. You can also contact Mazda customer service at 1-800-222-5500, and you should check your vehicle's VIN for open recalls.

If you tow a trailer with your 2017 CX-5, have the trailer lights checked and schedule the free repair with a dealer as soon as you receive the notice.

Check whether this recall is open on your vehicle

The repair is normally free at an authorized dealer.
