I was driving through the tollbooth on the bayway in [XXX] , I stepped on the brake to slow down and all kinds of warning lights lit up in the car showing the brakes were not working. Anything automatic with the brakes failed. I had to stand on the brakes to get the Traverse to stop. The issue was confrmed to be the master brake cylinder I was lucky they had it in stock at Maher Chevrolet in St Petersburg. My grandson was supposed to be in this car the next day driving over the skyway bridge. The safety of children is being compromised. Please issue a recall!!!!!

Vehicle: 2025 Chevrolet Traverse On [XXX] at approximately [XXX], while driving south on [XXX] , my vehicle suddenly shut off without warning resulting in a complete electrical failure. During this event, I lost the ability to accelerate, activate hazard lights, unlock doors, open or close windows, or use the OnStar system. The vehicle restarted briefly but then shut off two additional times before I could safely move it off the road. There were no warning messages or signals prior to this incident. This created a serious and immediate safety hazard, as I was unable to alert other drivers or exit the vehicle during the failure. I am requesting a formal investigation into this issue, documentation as a safety defect, and immediate corrective action. This incident poses a significant risk to driver and passenger safety. The vehicle has been towed to the dealership it was purchased from. The problem has not been confirmed or reproduced by the service center. INFORMATION REDACTED PU...

ABS light and brake light illuminated at the time of failure. No other car symptoms noted.

The shark fin antenna cover became loose. The antenna then fell off at some point while driving. This coming off while driving poses a risk to others on the road as it may have fallen off and hit someone else. The only “warning” it gave was stating the emergency call system failure. When googling I found out what the problem may be from. After looking further there are multiple Chevy traverse owners with the same issue after going through a car wash.
