Car Accelerates On Its Own problems of the 2015 Dodge Charger

I was driving using my paddle shifters mounted to the steering wheel and I pressed the + shifter to upshift, but instead of going up to third gear the vehicle downshifted to first. Upon searching the internet for a fix for this issue, I have discovered that it is very common among other Chrysler vehicles, dating back to at least 2015 and still present in current 2019 vehicles, yet Chrysler has not issued a solution. This is obviously a very significant issue as this could cause damage to the cars engine, and could even cause accidents or speeding tickets as the car could accelerate suddenly when the driver is expecting to upshift. I have noticed this issue several times, it was certainly not a one-off and it is definitely not limited to my vehicle, as it is circulating around the internet as a common Chrysler problem. I have also experienced it in Chargers and challengers I have driven (I am a valet driver) there are several videos up on the internet documenting the issue.

Occurs when vehicle is in motion or stationary. Although problem is primarily observed while in motion. Accelerator/brake assembly moves towards the seat while vehicle is in motion. This causes increased pressure on the pedal unknowingly. If driving - the car will suddenly and unexpectedly accelerate, if braking - increased pressure causes unpredictable decrease in speed. The problem has been addressed by dealer twice on the same vehicle. The first time the switch was replaced which did not fix the issue. The second time the entire accelerator/brake assembly was replaced which did fix the issue. After less than one year the problem has occurred again. The problem is that even a small increase in pressure on the gas has a dramatic effect on speed and acceleration. It is almost imperceptible that the pedal is moving towards the driver while driving. The pedal will continue moving until at full forward (closest to the driver) or switch is used. The switch located on the seat will stop the movement and still operates to move the pedals back to their desired position.
