Summary: All Wheel Drive Equipment Mfg., Inc. (All Wheel) is recalling certain 2011-2012 Ford F-550 Super Duty chassis with a 6.8L gasoline engine, modified by All Wheel and equipped with certain Muncie Power Products PTO Assemblies. In the affected vehicles, oil may leak from the PTO pressure switch onto a thermal blanket covering the exhaust.
Consequence: The leaking oil may soak into the thermal blanket covering the exhaust, which when combined with heat from exhaust, may result in an increased risk of fire.
Remedy: All Wheel has notified the affected owners, and dealers will install a new pressure switch kit that moves the switch away from the exhaust system, free of charge. Owners were notified on June 10, 2014 by certified mail. Owners may contact All Wheel customer service at 1-800-311-4778.
Notes: Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.

Has your Super Duty been repaired?

Recalls here come from NHTSA’s records for the model and year. Not every vehicle of a model is included in every recall, and this site can’t see whether a repair has been done. Only a VIN lookup can tell you that.

Check your VIN with NHTSA

NHTSA’s VIN search doesn’t show recalls that were already repaired, recalls more than 15 years old, or some small manufacturers’ recalls. A Super Duty dealer can also check your VIN. Recall repairs are free.
