Buick LaCrosse

General Motors is recalling more than 14,000 cars in the U.S. and Canada for power steering and electronic stability control problems. The National Highway Traffic Safety Administration says the recall affects 4,077 Buick LaCrosse cars from the 2012 model year, and 10,344 Chevrolet Impala cars from the 2012 model year.

The recall affects Buick LaCrosse cars built between June 9, 2011 and July 2, 2011. The LaCrosse’s StabiliTrak system, which is GM’s name for electronic stability control, may have a malfunctioning sensor which could make it erroneously activate. This could make the car suddenly slow down and experience an abrupt change in handling. NHTSA says this could cause the driver to lose control of the car. GM dealers will reprogram the electronic brake control module for free starting this month.

Chevrolet Impala

In a separate recall, GM is recalling Chevrolet Impala cars that were built between April 19, 2011 and July 29, 2011. NHTSA says one of the Impala’s power steering hoses may have been misrouted to a location where it could touch or come too close to the catalytic converter. If the car is on, heat from the catalytic converter could melt the hose, causing power steering fluid to leak onto the catalytic converter, which could cause an engine compartment fire. GM dealers will make sure the hose is routed properly so it doesn’t come too close to the catalytic converter. Repairs are free for affected owners and will start this month.

If you own one of these cars and have questions, you can call Buick at 1-866-608-8080 or Chevrolet at 1-800-630-2438. You can also go to NHTSA’s site for more information.
