Car Accelerates On Its Own problems of the 2020 Jeep Grand Cherokee

With my foot completely off the accelerator, the vehicle spontaneously accelerates under certain conditions. While in standard or sport mode, in second gear going about 20mph, there is a reproducible rpm surge that causes the vehicle to lunge forward. This somewhat feels like being rear ended.

When using the rear park assist, with my foot completely off the accelerator, the vehicle has spontaneously accelerated while going in reverse, requiring me to hard break to avoid collision. This has happened multiple times.

I was slowly backing into a driveway when the Jeep Grand Cherokee suddenly accelerated on its own. I repeatedly hit the brake pedal but the Jeep wouldn't stop; instead it kept going faster. It smashed into the garage door and the brick wall of the garage, demolishing them. The Jeep was brand new with only 500 miles driven, and it was equipped with a complete safety package that should have automatically stopped it before an impending impact but it did not do so. This was an extremely terrifying experience and it felt like a nightmare.
