Unexpected Loss of Engine Braking
Drive Train, March 15, 2013
RepairPal Expert Overview
Our Quick Take:
The transmission can unexpectedly shift into the "Sport" mode while driving, eliminating the transmission related engine braking.
What Should You Do?
Owners of affected vehicles will be notified beginning March 28, 2013. If the transmission is not functioning as you would expect, or you don't received recall notification and you feel you should have, please contact your General Motors dealer. They may ask for your vehicle identification number (VIN), so please have it handy when you call. The General Motors recall number is 13053.
When driving, if you let your foot off the accelerator, the engine will provide some braking effect unless your transmission is in "Sport" mode. Certain vehicles are being recalled because the transmission may unexpectedly shift into its "Sport" mode, removing the engine braking effect on these vehicles. Unexpected loss of engine braking can increase stopping distance, increasing the risk of a crash. Dealers will update the software in the transmission control module to correct this concern.
