Delay in control and involuntary clamping of Wheels Collider

I was making a small scene for a project at the institute. I tried to implement the gears, but I couldn't. I rolled everything back as much as I could, but now the car is behaving strangely. If you press the gas, it will accelerate even if you've already released it. There's also a noticeable delay before braking or starting.

The most interesting thing is that the car drives automatically by holding down the gas button for about as long as I hold down the button.
