While slowing down approaching a red light with the gear in L (regenerative braking), the car was in electric mode and traveling at a low speed (under 10mph and likely less than 5mph) when the passenger side front tire went into a large but shallow pot hole at which time the car felt like it accelerated (at the very least deceleration ended). My foot was already on the brake pedal (not sure if I was pressing it); however, I immediately mashed the brake pedal down as far as it would go. At first this did not seem to have any effect. After a moment, though, it finally kicked in and the car stopped immediately. I do not believe I hit the car in front of me (which was completely stopped). However, that driver wasn't sure if I did and asked for my information (there was no paint transfer or any marks on my car--there was a mark on the other vehicle which I believe was already there and the other driver wasn't sure and wanted to talk to her husband about it). Note in the later section that asks "was there a crash?" I am marking no as I do not believe there was a collision nor is there any physical evidence on my car of a collision. However, the other driver may dispute that.

Vehicle brakes fail to fully engage intermittently. When slowing down on multiple separate occasions, the brakes work initially, then, the car feels like it's sliding on ice (dry summer roads) then the brakes engage again. The brake peddle generally feels normal at first, then goes soft and sinks. I've taken the vehicle to the dealership on multiple occasions who've stated there's nothing they can do. This is a serious safety concern to just send someone on their way with. I've also been working with General Motors. While working with GM, they recommended I take the vehicle to a different dealership for a second opinion. The new dealership found error codes outlining the traction control module is malfunctioning and electrical ground issues exist.

This electric car has regenerative braking. Besides being in the regular braking, there is a pure regenerative braking paddle on the steering wheel. But when you use this brake, the brake lights to not turn on. This is a major hazard as I use this brake all the time and cars behind me do not know I am braking and have almost rear ended me. Chevy dealer says that is the way it is designed and is functioning perfectly. Why has this been approved to design a braking system without any warning lights" what can be done about this"

I was approaching a sudden red light and applied my brakes hard but not too hard (I did not suddenly slam the brakes). The brakes applied as expected at first but the brakes let up some and my vehicle failed to decelerate for about half a second before the brakes applied again and decelerated to a stop. I was not able to depress the pedal further when it was clear that the brakes were not decelerating.
