A heated windshield washer system that is prone to overheating and catching fire has prompted the recall of nearly one million General Motors cars, trucks and SUVs. According to General Motors, a short circuit in the circuit board that controls the windshield washer system could cause a grounding wire to overheat. That could lead to smoke and the malfunctioning of other electrical components, GM said in a letter to the National Highway Traffic Safety Administration (NHTSA). There is a possibility this could lead to a fire.

According to General Motors, there have been at least three fires cause by this defect, but no injuries.

General Motors says that dealers will install a fuse that will shut off the system in the event of a short circuit to correct the problem. However, the company has not yet provided the NHTSA with a schedule detailing when owners of affected vehicles will be notified.

The General Motors recall involves 944,000 trucks, 850,000 of which are in the U.S. The models listed below, if they’re equipped with a heated windshield washer fluid system, are subject to the recall:

• Model year 2006-08 Buick Lucerne sedans and model year 2008 Buick Enclave SUVs.
• Model year 2006-08 Cadillac DTS sedans and model year 2007-08 Cadillac Escalade, Escalade ESV and Escalade EXT SUVs.
• Model year 2007-08 Chevrolet Avalanche and Silverado trucks and Suburban and Tahoe SUVs.
• Model year 2007-08 GMC Acadia, Yukon, and Yukon XL SUVs and Sierra trucks.
• 2008 Saturn Outlook SUVs.

The fluid heating system is a popular option on many of General Motor’s large cars and SUVs. It is used in cold weather to heat windshield washer fluid before spraying it onto the windshield, where it can melt ice and frost on the windshield.
