What's wrong, in plain English
On some Acadia vehicles, a module that helps control the air bags, called the sensing diagnostic module, may have been left in a factory 'manufacturing mode' and never switched on before the vehicle left the assembly plant. Because this module was not activated, it may not be able to function the way it is supposed to when it is needed.
What you should do
2. Contact GMC customer service (1-800-462-8782) with any questions — affected vehicles will be returned to the assembly plant for the module to be activated.
3. The repair is free.
