The National Highway Traffic Safety Administration and General Motors are recalling more than 4,000 Buick LaCrosse vehicles for failing to meet federal requirements for electronic stability control, or ESC.

According to NHTSA, certain models of the 2012 Buick LaCrosse were manufactured between June and July with an improperly calibrated Stabilitrak ESC system. The flaw may prevent the control system from detecting malfunctioning sensors and fail to alert drivers of a problem with the Stabilitrak feature. The result: The ESC may activate improperly, causing sudden and unexpected changes to how the sedan handles which may lead to a collision.

GM is expected to alert affected LaCrosse owners this month to bring the to their local dealerships. Mechanics there will reprogram the Stabilitrak's electronic brake control module free of charge.

For more information, consumers can call the toll-free number for Buick (866-608-8080) or visit the NHTSA website: www.SaferCar.gov.
