GM Recalls 2012 Chevrolet Equinox, GMC Terrain Models

General Motors is recalling about 34,000 Chevrolet Equinox and GMC Terrain models to fix a problem with the tire-pressure monitoring system.

The company said that the tire-pressure warning light on the recalled vehicles does not illuminate until the cold pressure is more than 25% below the recommended pressure.  Under federal regulations, it's supposed to illuminate at the 25% mark, not below it.

Underinflated tires can cause tire overloading and overheating, which could lead to an accident, as well as premature wear, poor handling and poor economy.

GM dealers will update the control module free of charge.

Customers can call GM at  1-800-630-2438 and GMC AT 1-866-996-9463.
