Vehicles Affected: About 490,000 General Motors pickup trucks and full-size SUVs that use the 6L80 six-speed automatic transmission, which includes all 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, as well as the 2015 Chevrolet Suburban and Tahoe and 2015 GMC Yukon and Yukon XL.
The Problem: A hose clamp connecting the line from the oil cooler to the transmission, if not securely seated and attached, can leak or oil or come loose. If the oil makes contact with a hot surface it can ignite and result in a vehicle fire. To date, GM is aware of three incidents and no injuries.
The Fix: GM dealers will inspect the fitting and make the proper adjustments as needed. The first contact letters should be going out to truck owners by the week of April 28, 2014.
What Owners Should Do: Chevrolet and GMC owners can call 866-694-6546 or 866-790-5700 for more information.
