Several owners of the 2011 Buick LaCrosse have reported that their vehicles have steering issues, most commonly a tendency to drift to the left if not constantly corrected during driving. This tendency is most pronounced on sloped roads. Some owners report this has been referred to as a "radial drift" issue by dealers, but many owners also report that adjusting the toe-in and camber of the SUV's wheels or replacing its tires has fixed the issue for them. Recurrent check engine lights every few thousand miles are another issue reported by some owners of the LaCrosse. The cause of this issue may be carbon build-up in the engine's cylinders due to coolant leakage into the cylinders, but no definitive cause common to these cases are known.

Owners of the 2011 LaCrosse whose vehicles are involved in the power seat adjustment recall should consider having that issue addressed as soon as possible. This recall involves a bolt that secures the front seat at its selected height. Failure of the bolt can cause the system to disengage and suddenly drop the front seats to their lowest possible height, posing a potential danger if this occurs while the vehicle is in motion.
