If you believe that your vehicle has a defect which could cause a crash or could
cause injury or death, you should immediately inform the National Highway Traffic
Safety Administration (NHTSA) in addition to notifying General Motors.
If NHTSA receives similar complaints, it may open an investigation, and if it
finds that a safety defect exists in a group of vehicles, it may order a recall
and remedy campaign...
