Certain 2012 model year General Motors small SUVs are being recalled due to a potentially faulty tire pressure monitoring system. Failing to comply with the Federal Motor Vehicle Safety Standard number 138 are approximately 33,964 GMC Terrains and Chevrolet Equinoxs. According the safety standard, a vehicle’s tire pressure monitoring system should illuminate a warning light when a tire’s pressure is 25 percent below the recommended cold pressure. On 2012 model year crossovers built from July 18 through September 6, 2011, this light will not show itself unless the pressure falls further below the required levels.
Underinflated tires can cause all sorts of issues from poor handling, dimensioned fuel economy to potential blowouts. In order to remedy the issue, GM dealers will “reflash” and update the body control module at no cost to owners. Notification will begin before the month of October is over.
