General Motors and the National Highway Traffic Safety Administration have issued a recall for several different Chevy, GMC, Buick and Cadillac models as the vehicles’ transmissions may leak transmission fluid.
The problem: according to a GM filing with NHTSA, the start/stop accumulator endcap on affected vehicles may have missing or loose bolts.
The hazards: the filing indicates that missing or loose bolts on the start-stop accumulator endcap could result in a transmission oil leak and may progress to a loss of propulsion, thereby increasing the risk of a crash. A transmission fluid leak in the presence of high heat or some other ignition source may increase the risk of a fire, as well.
