The hazard poses a serious risk of illness, injury, or structural failure. Stop using the product immediately and contact the manufacturer for a refund or repair.
Our severity reasoning: The recall involves a structural vehicle defect (battery cable routing) that poses a risk of vehicle fire, which aligns with the rubric criteria for a Severe rating.
Plain-English summary
Mack Trucks, Inc. is recalling certain model year 2008-2011 GU heavy trucks manufactured between September 12, 2007, and April 8, 2011. The recall involves trucks equipped with a four battery cable design.
The defect involves the routing and clipping of the battery cables, which may allow them to come into contact with frame hardware. This contact can cause chafing that wears down the cable insulation, potentially leading to a short circuit. A short circuit can potentially cause a vehicle fire.
Owners should contact Mack Trucks at 1-800-866-1177 to schedule a free repair. Dealers will re-route the battery cables and replace them if chafing has occurred. The safety recall began on July 11, 2011.
