According to the National Highway Traffic Safety Administration, the monitors are required to be calibrated to illuminate a warning light any time a tire is inflated to 25 percent below the recommended level. The sensors in 2012 Equinox and Terrain models may not illuminate until the tire is much further below that threshold. NHTSA says that improperly inflated tires could lead to an accident due to premature wear and excess heat.
In addition, improperly inflated tires can reduce fuel economy and result in poor handling as well. GM will update the body control module on affected vehicles free of charge once the recall gets under way this month.
Of course, this is as good of a time as any to remind drivers to always check their tire pressure at regular intervals, regardless of what the light on the dash says. Hit the jump to see the full recall notice for yourself.
