Your vehicle’s transmission is designed to transfer engine power to the driveshaft. The start-stop accumulator shuts down the engine when it is not in use to achieve better fuel economy and cut down on emissions.
Each start-stop transmission accumulator is attached using four bolts. In the case of the recalled vehicles, due to a supplier software error, two of the required bolts are missing.
Missing bolts can create a number of issues:
- Transmission oil leak: A leak may damage other engine parts, and driving the vehicle without the proper amount of oil or transmission fluid may damage the engine.
- Loss of vehicle power: A loss of power may prevent the driver from accelerating into a busy road or onto a highway, increasing the risk of an accident. A power loss may also reduce the driver’s ability to speed up to avoid an accident. Finally, the vehicle may slow down on its own until it comes to a complete stop, increasing the risk of being struck by another vehicle coming up from behind.
- Increased risk of fire: A fire can injure the vehicle occupants, or cause the driver to lose control and cause an accident. This article explains what you should do if you believe your vehicle is on fire.
To fix the issue, dealers will need to check the start-stop accumulator end cap and determine if any bolts are missing. If they are, the dealer will replace the end cap at no cost to the owner. GM expects the recall to begin on December 14, 2020.
