I get a "Service Safety Restraint System" warning sporadically when driving. No known cause and the vehicle has never been in an accident. This started happening after my last service at Capital Buick GMC in Smyrna, GA on January 6th, 2023.

Sierra 1500

  • miles
Airbag light and "Service Safety Restraint System" keep flashing on and off intermittently. Sometimes every 5 seconds. Sometimes once or twice a day. This is a known issue with 2021 GM trucks and SUVs. Trying to get vehicle in for service but dealer said they are booked 2 weeks out and won't given loaner vehicles at all anymore. The vehicle has less than 2000 miles on it.
