2012 Chevrolet Impala, Buick LaCrosse: Recall Alert

August 15, 2011

General Motors is recalling 14,421 new vehicles in the United States to address two separate concerns: inspection of power steering hoses in some 2012 Chevrolet Impalas and reprogram of software in certain 2012 Buick LaCrosse models.

The larger of the two campaigns involves some 10,344 2012 model year Chevrolet Impalas to inspect the power steering hose and make any necessary corrections. According to GM, the defect was discovered during production at the Oshawa, Ontario, Canada plant where the Impala is built.

A notice on the National Highway Traffic Safety Administration (NHTSA) site indicates that affected vehicles were manufactured from April 19 through July 29, 2011.

The NHTSA notice on the Impala recall campaign, ID No. 11V398000, details the issue: The upper power steering hose may have been misrouted so that it can come in close proximity to and/or contact the catalytic converter. With the engine on, the heat from the catalytic converter may melt the power steering hose.

Should power steering fluid flow onto the catalytic converter, an engine compartment fire could occur.

GM dealers will inspect affected Impala models to ensure proper routing of the upper power steering hose and make any necessary repairs free of charge. The Impala safety recall is expected to begin on or before August 12.

Chevrolet Impala owners with any questions or concerns may contact Chevrolet at 800-630-2438. GM’s safety recall campaign number is 11224.

The second recall involves 4,077 2012 Buick LaCrosse models manufactured from June 9 through July 2, 2011. The issue here, as outlined in a notice on the NHTSA site, is an incorrect calibration on the electronic brake control module that may cause the StabiliTrak electronic stability system to not properly detect malfunction of a sensor and subsequently fail to illuminate a system warning light.

The potential consequence of a sensor malfunction is that the electronic stability control system could falsely activate. This may result in sudden vehicle handling and deceleration changes that may cause loss of driver control and could result in a crash without warning.

GM dealers will reprogram the electronic brake control module free of charge. The Buick LaCrosse safety recall, with GM safety recall number 11222, is expected to begin during August 2011. Owners of 2012 Buick LaCrosse models with any questions or concerns may contact Buick at 866-608-8080.

Alternatively, owners of model year vehicles involved in either campaign may contact the NHTSA’s Vehicle Safety Hotline at 888-327-4236 or go to https://www.safercar.gov.  Refer to the appropriate NHTSA campaign ID number for the Chevrolet Impala or Buick LaCrosse recalls.

GM says it knows of no crashes, injuries or complaints related to either campaign condition.
