2020 AMG GLC 43 coupe here in Harrison, NJ. My driving style with this vehicle isn't different in any relevant way versus with past vehicles. There is an acceleration dead spot which is the default occurrence when I am coasting at a low speed and then go to accelerate. Common scenarios are driving toward an intersection and rolling forward as you determine if you are clear to go and then accelerating, or slowing down to let a car in the lane next to you go by so you can then switch lanes and accelerate. I swear, I've almost gotten killed a few times when I had time to go but only if I hustled; depress the accelerator, and nothing happens for a full second. Then I go from having enough time to almost getting hit.

Sometimes after I hit the brake (hard or soft) but need to step on the gas again, the car pauses and does nothing for over a second, making it dangerous if you need to make a turn. Sometimes the car is confused whether to go fast or slow down so it does nothing and does not re-act to the driver pushing the pedal down. This situation can leave the driver in dangerous situations regarding on coming traffic
At around 11pm on Monday, Sept 20, 2021 I was driving approximately 65 mph on the highway when the vehicle began to abruptly decelerate for no apparent reason, even when I was pushing on the accelerator pedal. When I would push on the accelerator I could hear the engine revving, I confirmed the car was in the Drive gear but the vehicle began to lose speed rapidly and no matter what action I took the car was only slowing down and had to quickly find an emergency area to pull over. My vehicle is available for inspection. This incident was a very scary situation that put my life and others at risk. I was on a two lane highway in a construction zone and there was no shoulder available to pull off safely. There were tractor trailers that had to swerve to avoid rear ending me in the roadway and I was afraid I was going to be involved in a major accident. In the end I was able to pull into a break in the Jersey barrier to get out of the lane of travel. I have a young baby and do not want
