Two popular Chrysler models -- the Jeep Grand Cherokee and the Dodge Durango -- are being investigated by the National Highway Traffic Safety Administration (NHTSA) after more than 40 owners complained that their vehicles caught fire due to a short in the electrical system. The investigation focuses on Grand Cherokees and Durangos from the 2011, 2012, and 2013 model years.
According to a bulletin from NHTSA's Office of Defects Investigation, the problem is linked to the wiring for the vanity lights located on the front sun visors. Early suggestions indicate that the wiring may have been damaged by screws that hold the sun visors in place. Since there's no dedicated fuse for the vanity lighting system, any short would continue to cause problems until it resolves itself or until the vehicle switches off. So far, though, there has not been a recall.
NHTSA says "Customers reported a range of fire conditions ranging from minor overheating to an open flame at the headliner and/or sun visor material while driving the vehicle. In some reports the fire spread to the front seats and/or door panels of the vehicle. In one report, the sunroof was damaged causing the glass to shatter."
To date, NHTSA has received five complaints about the problem, but Chrysler has received 36 more. Nearly all of the complaints on file involve some sort of fire.
Given the nature of the problem and the potential risk it poses to vehicle occupants, carconnection.com says NHTSA has fast-tracked this investigation, zipping past the Preliminary Evaluation phase and moving quickly to the Engineering Analysis. If the agency determines that there's a consistent flaw with the wiring on the Grand Cherokee and the Durango, the third and final step would be a full recall. Should that happen, it would affect some 593,299 vehicles in the U.S. Stay tuned!
