Based on documents filed with the National Highway Traffic Safety Administration, the automaker ordered a recall of 194,105 vehicles in the United States. The list includes the 2018 Malibu, 2019-20 Blazer, 2018-19 Cruze, Equinox, and Traverse from Chevrolet; 2018-19 LaCrosse sedans, 2019-20 Encore and Enclave units from Buick; 2018-20 Terrain, 2019-2020 Acadia vehicles from GMC; 2019-20 XT4 and 2020 XT6 units from Cadillac.
The recall was prompted by a possible transmission oil leak caused by missing bolts on the start-stop accumulator end cap. In the bolts’ absence, there is a possibility for oil to leak to the transmission, which could then cause a lack of power in the vehicle. This also increases the chances of a fire, according to GM.
The automaker, however, clarified it is not aware of any reports of crashes or injuries that may be related to the problem.
To fix the issue, technicians are instructed to install bolts on the start-stop accumulator in case there is none. Owners of the recalled vehicles are advised to visit their local dealerships where a technician can inspect the vehicle properly and perform the necessary fix free of charge.
Those found to have the necessary bolts in place upon inspection will not need any repairs. GM is set to send out recall notifications to customers starting December.
