WASHINGTON, D.C. -

National Highway Traffic Safety Administration officials recently noted General Motors is recalling a pair of 2012 sedans, totaling almost 15,000 units.

The models included in separate campaigns are the Buick LaCrosse and Chevrolet Impala.

In connection with the LaCrosse, NHTSA explained the recall stems from failing to conform to requirements of Federal Motor Vehicle Safety Standard No. 126 regarding the electronic stability control systems.

Officials said in LaCrosse models manufactured between June 9 and July 2 of last year, the Stabilitrak system has an incorrect calibration that may cause the system to not properly detect if a sensor was to malfunction. As a result, the warning light indicating the system is not operating properly would not illuminate as required in the safety standard.

As a result, federal officials believe improper diagnosing may cause the ESC to falsely activate, resulting in sudden changes in vehicle handling and deceleration, particularly at higher speeds. NHTSA contends this condition may cause the driver difficulty in maintaining the unit’s desired path of travel and forward speed, potentially causing a crash without warning.

NHTSA noted franchise dealers have been instructed to reprogram the electronic brake control module for free beginning this month. The agency calculated the recall involves 4,077 units.

In the meantime, potentially effected LaCrosse owners can contact Buick at (866) 608-8080 and reference recall No. 11222.

The other GM recall for the Chevrolet Impala includes more units. In fact, NHTSA pinpointed it at a total of 10,344.

Federal officials asserted that 2012 Impalas manufactured between April 19 and July 29 of last year have a flaw associated with a hose connected with the power steering system.

NHTSA determined the upper power steering hose might have been misrouted so that it can come in close proximity to or even touch the catalytic converter.
With the engine running, the agency believes heat from the catalytic converter may melt this power steering hose. As a result, NHTSA fears power steering fluid could flow onto the catalytic converter and an engine compartment fire could occur.

Officials explained Chevrolet dealers have been told to inspect and ensure that upper power steering house is routed correctly and make any necessary repairs for free.

NHTSA said GM already launched this campaign, but potentially effected owners also can connect with Chevrolet at (800) 630-2438 and mention recall No. 11224.

Recently, another NTHSA investigation cleared GM from needing to bring back more than 266,000 Chevrolet Tahoes and GMC Yukons from the 2007 model year. Auto Remarketing published the details of that decision here.
