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.

Vehicle purchased new in 2021; has less than 5,600 miles on it. Service Restraint System indicator light began coming on in September. At first intermittently, then every few seconds. Sent vehicle to dealer for repair on 9/27/21. Dealer states not safe to drive because airbag may not deploy in case of accident.

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.

Returned home after some shopping. Parked truck in drive way. Approximately 5 minutes after returning home my wife saw truck smoking from under the hood. Within another minute or two there were visible flames coming from the back edge of the hood. We called 911. Within 5 minutes the entire front end of the truck was engulfed in flames. The fire department arrived and put out the fire but the entire front and cab of the truck was destroyed. Fire investigators determined fire started at back of engine compartment near battery. Vehicle was stopped parked in off condition. In my driveway. No mechanical problems were noticed on ride home and there were no panel alerts for problems.
