Hey can anyone help me with the unusual random bouncing/jumping of vehical whenerver I hit play?

[hksinfinity]

I have tried adjusting the physics asset with wheel piviot and as well as turning off/on the collision but it still jumps, I am using Third person template and imported vehical template and replace the mesh with different model with almost same dimensions, everything works perfect but the random jumping is not stopping.

Can you check if there’s an animation playing on the mesh?
Because with this lack of information it’s hard for us to know what could be going wrong.

Currently there are no animations on the vehical mesh, I was thinking to add door opening and closing but due to this error I skipped it,

please let me know what you need from my side to help me fix this,
