2011 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.

Electronic Climate Control May Not Function Correctly

The HVAC system may stop functioning due to a software issue in the climate control module. System failure would reduce the driver's ability to command the defrost function. This can reduce visibility, increasing the risk of a crash. To correct the problem, dealers will reprogram the electronic control module for the HVAC. The recall is expected to begin by March 11, 2011. The General Motors recall number is 11057.
