Carrier/rack problems of the 2016 Chevrolet Corvette

While operating vehicle loses the ability to accelerate, which has resulted in 3 near miss collisions, (one head on incident and two side impact collisions. ) the side impact near miss collisions were after making an attempt at a left turn where there was plenty of time initially to complete the maneuver, the car completely loses the ability to accelerate and is dead in its tracks on the road. The head on near miss collision occurred during an attempt to pass another vehicle. As the car accelerated in the passing zone, and pulled next to the vehicle being passed, the ability to accelerate was lost and thankfully the other driver was able to avoid the collision prior to the ability to accelerate resuming. When the ability to accelerate voids, pushing the gas pedal has no impact on acceleration. These 3 occurrences were the most pronounced and potentially fatal, however, there have been a myriad of instances where the ability to accelerate has stopped momentarily. I am also concerned with the overwhelming chemical odor (plastic smell) emanating throughout the car. After a year of ownership, and leaving windows open while stored, it persists to the point that it remains overwhelming with the windows up and top on. Due to fears for my safety and wellbeing I have been unable to take pleasure in the vehicle I purchased exclusively for enjoyment.
