BTW: What happens if you fully press both the acceleration and brake pedals? I would hope for the brakes to be more powerful and stop the car, is that the case?
The brakes do not have to be stronger, it’s handled in software.
If the accelerator is pinned down, letting up on the brake will cause the car to start accelerating again. So you have to keep on the brake and then put the car in park. Pressing the accelerator while in park does nothing.
Much to the frustration of those of us who occasionally engage in some left-foot braking. (Though TBH in my experience it's usually more effective in FWD cars.)
There is a video floating around of this issue, and based on that I'd call it an issue in all shipped trucks. While only a couple had it loose from the factory, the fact the two plates are only press fitted and when it slides up there is a perfect nook for it to get stuck in is a huge problem.
If I was a Cybertruck owner I'd inspect it at least every week and schedule the recall work ASAP.
You get a “both pedals pressed” alert and the accelerator is ignored, so the brakes don’t even need to overcome the engines. The behaviour is logical at least since tesla added blended braking (though I’d assume it also did that before then).
However as soon as you release the brakes the car starts accelerating as whatever the throttle is at again.
