2023 Buick Envision

While driving in traffic, after changing lanes, the vehicle experienced a complete electrical shutdown without warning. The engine shut off, the dashboard went completely black, and hazard lights were not functional. There were no warning lights, messages, or audible alerts prior to the failure. The vehicle was in active traffic and, stopped without power steering or brake assist. After opening the hood, multiple wiring harnesses and a loose battery cable were visually observed. When wiring was physically moved, electrical power was immediately restored. Upon restart, the vehicle hesitated to start and then displayed messages instructing the driver to open and close the driver and passenger windows, indicating a full system reset due to power loss. We were able to return home safely. Parked the car, and obtained a rental. The vehicle had been serviced by the Buick dealership where the car was purchased, three days earlier. Two days after the incident, I was able to speak to someone at the dealership, who stated they may have bumped something. The vehicle was towed to the dealership, and assessed. The dealership later documented a loose battery cable and promised to replace a fatigued clip, but denied responsibility for the incident. I contacted the manufacturer, and was referred back to the dealership.The vehicle has only been inspected by the dealership. This incident created a serious safety risk, to our lives, as well as our fellow drivers' lives, as the vehicle lost all electrical power, including required safety lighting, while in traffic, without warning. The vehicle is available for inspection, upon request.

When letting off the accelerator to slow coming to a stop I would press the brake pedal. but the motor would increase RPMs and I had to use both feet to stop the vehicle. Then I had to put the car in neutral and the RPMs would increase even though I was at a stop and then I had to put it in Park before the RPMs would drop. I removed the driver's floor mat encase it was effecting the accelerator. The vehicle didn't act this violent but it failed to decelerate several times before I could get it to my local dealer.

The customer service recall caused the battery to drain in which caused all electrical functions to malfunction. My breaks locked up while I was driving. My abs light came on, transmission light, collision, check engine, and steering wheel light came on. It was multiple incidents, but with my breaks locking up is the approximate date I put in statement. I was driving in a parking lot.
