Recalls, owner-reported complaints, investigations and safety data

Data refreshed

Owner complaintsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The defect: Trans-Air Manufacturing Corp. (Trans-Air) is recalling certain model year 2006-2014 GM G3500 and G4500 vehicles modified with Trans-Air add-on compressor mount kits, part numbers 4012506-01, 4012506-02, 4013126-01, 4013126-02, 4013235-01, 4013235-02, 4012909, 4013125, 4013222 and 717173 installed by Trans-Air personnel.

The risk: If the power distribution terminal strip has a poor connection or a loose connection, the strip may arc or overheat, increasing the risk of a vehicle fire.
The remedy: Trans-Air will notify owners, and dealers will inspect the power distribution terminal strip connection, correcting it as necessary, free of charge. The recall began on May 29, 2015. Owners may contact Trans-Air customer service at 1-800-673-2446.
