General Motors will recall the recently launched 2014 Chevrolet Silverado 1500 and GMC Sierra 1500 pickups, and 2015 Chevrolet Suburban and Tahoe and GMC Yukon and Yukon XL SUVs equipped with a six-speed automatic transmission to check an oil cooler line.

The recall involves about 490,200 vehicles.

“GM has determined that these vehicles may have a transmission oil cooler line that is not securely seated in its fitting.  If the line is not securely seated and transmission oil leaks from the fitting, the oil could contact a hot surface and result in a vehicle fire. GM is aware of three incidents and no injuries,” the automaker said in an emailed statement.

GM dealers will inspect the fittings for leaks. First owner letters should go out in the week of 28 April, 2014.
