Ok I am testing this now. This sound like it could be a serious bug that affecting some joints, like the car and the player controller.
first I will see if normal generation when convex cast works with compound is consistent.
The engine does not really care what direction the normal point but for the end user this is important and we cannot have that kind of inconvenient, can we.

Ok problem one covered, normals are now consistent when casting on compound and scene collisions.

I will try the secund test now.

Ok I just replace the old demo with the second one and this is the result I am getting now


    contact 0 at -49.000000 -9.001953 0.000000, normal 0.000000 1.000000 0.000000
    contact 0 at -50.002197 -9.002148 0.000000, normal -0.082260 0.996611 -0.000000

As you can see the normals are consistent on the edge and in the flat part of the compound.
You can get 2.20 now

Is the fix included in version 2.20? I haven't tried it yet, but the version 2.20 on the download page seems to be dated a week before your reply here. And I will again be needing the Linux SDK too..
