General Motors will recall almost 500,000 late model pickup trucks and large sport-utility vehicles to fix a potential oil leak.
The automaker also said it will resume selling certain Chevrolet Cruze sedans it had pulled from the market last week after inspecting a potentially defective axle part.
The truck recall includes 490,200 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 6-speed automatic transmission.
GM said some of the vehicles may have a transmission oil cooler line that is not securely seated in its fitting. This could cause a transmission oil leak that could lead to a fire. GM is aware of three such incidents but no injuries.
Owners will need to take their vehicles to a GM dealer, where mechanics will inspect the fittings for leaks and make any needed repairs.
The automaker also is recalling about 172,000 Chevrolet Cruzes equipped with 1.4 liter turbocharged gasoline engines to replace a right front axle half shaft that can fracture and separate without warning during normal driving. The cars are from the 2013 and 2014 model years.
If the part breaks while the vehicle is in operation, a driver would be able to maintain control over the vehicle but it would lose power to the wheels and would coast to a stop.
If it breaks when the car is parked on a hill, it could cause the vehicle to coast into another car or object and could injure pedestrians, GM said.
The car company knows of “several dozen” fractures from warranty data. GM said it is unaware of any crashes or injuries related to this condition.
These big recalls come as GM Chief Executive Mary Barra is scheduled to testify Tuesday before Congress about the reasons for delays in recalling about 2.6 million vehicles to repair a faulty ignition switch that is linked to 13 deaths.
The automaker is facing probes from the National Highway Traffic Safety Administration and the Department of Justice into why it did not move more quickly to fix the issue.
