TLDR is that they are using a custom COM override, and then the colliders were being altered in any way their tests were breaking.
This was tracked down to the COM override being factored into the Mass and Inertia on the VehicleMovementComponent, but this changes when UpdateMassProperties is called on the body instance.
NA here since we have the underlying code below and the logic issue.
There's no existing public thread on this issue, so head over to Questions & Answers just mention UE-259561 in the post.
