Hello.

Thank you for the report. Could you please provide more information? Were you using any mods? Was this in Editor or Multiplayer?

I'm was playing in editor. I do have mods installed but it could be from the mod "Real Engine" from workshop. However, in the past, I used without any mods but vehicle hit an object, it will spiral out of control or bounce off.

So this is not confirmed to be happening in unmoded Arma 3, right? Try to reproduce this without mods and let us know.
