RepairPal Expert Overview
Our Quick Take:
The low tire pressure warning light may not illuminate as expected when a tire is 25% below the recommend cold tire pressure.
What Should You Do?
General Motors will notify owners of affected vehicles during October 2011. There may be no symptoms related to this recall. If you don't receive notification and you feel you should have, please contact your dealer. It's helpful to have your vehicle identification number (VIN) when you call.
The tire pressure monitoring system is designed to illuminate the tire pressure warning light when the tire pressure in any one tire is 25% below the recommended cold tire pressure. On these vehicles, the light will not illuminate until the tire pressure is more than 25% below the recommend cold tire pressure. Underinflated tires can result in the tire overheating, which could lead to a blowout and a possible crash. Underinflated tires also affect tire wear, vehicle handling, and fuel economy. Dealers will update the Body Control Module software to correct this concern. The General Motors recall number is 11261.
