GM Recalls SUVs to Fix Tire Pressure Monitors

General Motors is recalling more than 36,000 Chevrolet Equinox and GMC Terrain crossover SUVs to fix tire pressure monitors that don’t work right.

The company says the systems in the 2012 vehicles should warn drivers when tire pressure drops 25 percent below the recommended pressure. But in the recalled vehicles, the warning light doesn’t come on until the tire pressure falls more than 25 percent.

Federal safety regulators say underinflated tires can overheat. That could lead to a blowout and a crash. But GM says it knows of no crashes or injuries caused by the problem.

The recalled vehicles were built between July 18 and Sept. 6 of 2011. Dealers will update a computer that controls the monitors free of charge.
