2013 Buick LaCrosse RecallsThe Generator Control Module May Fail
eAssist is a hybrid drive system that includes an electric motor to assist the gas engine under certain driving conditions. These vehicles are being recalled because there may be an internal fault with the Generator Control Module (GCM). The module could allow the battery to discharge to the point were the vehicle could stall and/or not start. Also, a burning smell, smoke, and/or a fire could develop in the trunk. Dealers will inspect and replace the GCM to correct this concern.
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.
