2012 Chevrolet Equinox, GMC Terrain: Recall Alert

October 26, 2011

General Motors is conducting a voluntary recall of 33,964 2012 Chevrolet Equinox and GMC Terrain SUVs to address an issue with the tire pressure monitoring system, which does not meet federal standards. Involved in the recall are 21,112 Equinox and 12,852 Terrain models.

A notice on the National Highway Traffic Safety Administration (NHTSA) site indicates the vehicles were manufactured from July 18, 2011 through September 6, 2011.

At issue is the fact that the tire pressure monitoring system (TPMS) is supposed to illuminate the tire pressure warning light when the pressure in a tire is below 25 percent of the recommended cold tire pressure. On the affected vehicles, the warning light does not illuminate until the tire pressure is more than 25 percent below recommended cold tire pressure.

While this may not seem like a big deal, underinflated tires can result in overheating and overloading, which could lead to a possible crash and injuries. Underinflated tires may also result in premature or irregular tire wear, poor vehicle handling and poor fuel economy.

How did GM discover the issue? According to GM documents, the problem was discovered by a company car driver who received a monthly vehicle status email from OnStar and noticed it was missing a report of the tire pressure. The driver contacted the OnStar team, which quickly determined that some of the subject vehicles had an incorrect recommended tire pressure stored in the vehicles’ body control module (BCM).

GM’s Product Engineering and Product Investigations teams sprang to work, investigated the issue to determine the root cause and found that it was limited to one assembly plant using an incorrectly configured data system to retrieve tire pressure data values to be downloaded into each vehicle’s BCM. The assembly plant corrected the problem. No other model year vehicles and no other assembly plants were involved in this issue.

GM dealers will update the body control module free of charge. The safety recall is expected to begin in October 2011.
