GM recalls 2012 Chevrolet Equinox, GMC Terrain for tire-pressure sensor fix

General Motors is recalling 33,964 Chevy Equinox and GMC Terrain crossovers from the 2012 model year to check for problems with the tire-pressure-monitoring systems. The vehicles were built from July 18 to Sept. 6, 2011.

The system is supposed to activate a warning light when the tire pressure falls more than 25 percent below the recommended inflation level. According to GM, some vehicles were programmed improperly.

Underinflated tires can cause several problems, the most dangerous of which is a blowout. Fuel mileage also suffers, along with other suspension components.

The fix involves updating the body-control module, free of charge. The recall is expected to begin this month.

Owners impacted by the recall can call (800) 996-9463 or go to www.nhtsa.gov for more information.
