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 to take my child in this car now for fear of it happening again.   I had noticed a hesitation in the vehicle before but this is the first time this issue has happened where the car would not accelerate.   I am taking the car into the dealer to see if there are any diagnostic codes and it has not been inspected by anyone. Additionally there were no warning lights, no tones, no check engine lights or anything to warn of the situation before or while it was happening. From the inside of the vehicle the car appeared to be normal but it was not clearly given the lose of power and rapid deceleration.","products":[{"type":"Vehicle","productYear":"2020","productMake":"MERCEDES-BENZ","productModel":"AMG GLC43","manufacturer":"Mercedes-Benz USA, LLC"}]}]}
