General Motors is conducting a safety campaign that affects 88,129 units of the 2018 GMC Terrain.

The SUVs, which were assembled between March 14, 2017 and May 22, 2018, have a software issue that could prevent the airbags from deploying in the event of an accident.

According to a document shared by the NHTSA, the problem is with the Sensing Diagnostic Module (SDM). The SDM senses the accident and automatically deploys the airbags, but due to an error, it may fail to do so in the aforementioned vehicles.

“In these vehicles, the SDM […] may not power down correctly when the vehicle is powered off”, the NHTSA explains in the description of the defect. “If this condition occurs, the SDM may be inoperative when the vehicle is restarted.”

When the system is not working, drivers will be warned via the airbag light in the instrument cluster. At the same time, the driver information center will display a “service restraint system” message and sound warning chimes.

General Motors estimates that approximately 1 percent of the 2018 GMC Terrain involved in this recall could be affected by the defect. The automaker is not aware of any accidents or injuries related to this condition.

The fix consistd of a simple software update that’ll be performed free of charge.

As usual, owners of the affected vehicles will be informed of the recall by the company. An official notification schedule has yet to be provided, but in the meantime, customers can contact the GMC customer service at 1-800-462-8782 to find out more about this safety campaign.
