Honda is voluntarily recalling 652 trailer-hitch accessory kits used on 2014 Acura MDX luxury SUVs due to a potential wiring problem that could impede braking, according to the National Highway Traffic Safety Administration. In a statement, Honda estimated that 340 of the kits may have already been installed on vehicles and that no crashes related to the issue had been reported.
The affected vehicles are equipped with trailer-hitch harness kits. According to Honda, the accessory wire harness was incorrectly assembled during production and may not properly power a trailer's accessory brake controller when installed using provided instructions; this potentially increases stopping distances and the risk of a crash when towing a trailer equipped with an independent braking system.
Honda will begin notifying owners Aug. 23, and dealers will re-label and repair the trailer-hitch subharness for free. Owners can call Acura customer service at 800-382-2238 or go to www.recalls.acura.com for more info; they may also call NHTSA's vehicle-safety hotline at 888-327-4236 or go to www.safercar.gov .
