Software Glitch Causes HVAC Problems on 2011MY Buick LaCrosse and Cadillac SRX Models

In the latest round of safety recalls, General Motors has issued a warning on certain 2011MY Buick LaCrosse sedans and Cadillac SRX crossovers due to a software glitch that may disable the driver�s ability to adjust the settings on the hearing, ventilation, and air conditioning (HVAC) systems.

�If this condition affects the defrost system when it is required, it may decrease the driver's visibility, and could result in a crash,� the National Highway Traffic Safety Administration (NHTSA) said on its website.

GM said that a total of 10,179 vehicles are affected by the recall, but it was not aware of any crashes or injuries connected to the problem.

The safety recall is expected to begin on or before March 11, 2011. Owners may contact Buick at 1-866-608-8080, Cadillac at 1-866-982-2339 or GM�s owner center at www.gmownercenter.com.

Cadillac's All-Wheel Drive Model Sales on the Rise in the U.S.A.

It was a time when associating Cadillac with all-wheel drive was considered to be a heresy. But mentalities have changed and more American customers are specifying their cars with the AWD option. GM�s luxury brand has registered a combined sales increase of 38% for its 4x4 SRX, CTS and Escalade models in the past two years. Specifically, one-third of the SRX crossovers, almost half of the CTS and three-quarters of the Escalade vehicles sold in the U.S. have been equipped with all-wheel drive.

Not surprisingly, the highest demand comes from cold weather and mountainous areas. Besides offering better traction on snow, the Cadillac AWD systems also promises to enhance handling and performance in normal weather conditions.

According to the Detroit automaker, AWD improves the SRX�s passing acceleration compared to the front-wheel drive version by transferring more torque to the rear wheels, while also reduces the over-steer tendencies manifested by the rear-wheel drive CTS during aggressive cornering.

�Cadillac�s investment in advanced AWD systems across the line-up is enhancing the brand�s reputation for performance,� said Don Butler, vice president of Cadillac marketing. �We�re able to offer luxury buyers exceptional ride, handling and control on a wide range of road conditions.�
