2012 Buick LaCrosse Recalls

Front Seat Height Adjuster

The driver's and/or passenger's seat may suddenly drop to its lowest position because a bolt securing the height adjuster can fall out. This unexpected movement of the driver's seat could cause a distraction, increasing the risk of a crash. Dealers will replace the height adjuster bolts in both front seats to correct this concern.

The 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.

Unexpected Activation of the Anti-Skid System

The anti-skid (stabilitrak) system may have an incorrect calibration, which can cause the system not to properly detect a sensor malfunction. A malfunctioning sensor may cause the stabilitrak (ESC) to falsely activate, resulting in sudden changes in vehicle handling and deceleration. These unexpected changes in vehicle handling may cause a loss of vehicle control. Dealers will update the electronic brake control module (EBCM) software to correct this concern. The General Motors recall number is 11222.

2012 Buick LaCrosse Reviews

worst car i have owned. engine surging problems which the dealership claims to not be able to find. replaced both rear bearrings, rack and pinion leaking, rotors and pads. hard idle, car almost wants to die. again dealership not able to detect since no codes set off by it. idle sensor already replaced. sharp looking car but dont let that deceive all the problems. ugh...
Very comfortable and very quiet, limited trunk space, V6 has big time power when you hit it (hang onto the wheel) fuel economy pretty good if you drive with a very light foot. If you don't watch it you'll not be happy with the fuel economy. Highway 34 Canadian mpg (20 %) less U>S> with cruise on 70 mph, city can get as low as 9 or 10 with a heavy foot or 20 watching it.
