Method WheelCollider.GetGroundHit and terrain changes causes unity crash
Sometimes method WheelCollider.GetGroundHit crashes unity if terrain height is changed, I'm still not sure for real cause.
1. Play scene "terrainbug".
2. Driver anywhere you like :D, after 15 second script "TerrainDeform" (attached on car) will begin spawn holes in terrain with 1 second interval.
3. Unity crash times can variate from 2 second to few minutes, but eventually it crashes.
Reproduced: 5.0.0b2, 5.0.0f4, 5.0.0b15
The fix available in 5.1.3p1 a patch release. Officially will be available in 5.1.4f1;

I have the same problem in 5.1.3f1 with error "m_InstanceID != 0".

"A fix will come later in 5.x."
The same for Unity v5.1.2f1 :(

We've just had this issue too on 5.1.1p2. GetGroundHit is being called from FixedUpdate.

Same problem with CubeCollider as described by DE-PANTHER.

Also happen with box collider or any other collider that destroyed while the wheelcollider touch it.
Simple example:
Use Edy's Vehicle Physics,
Take a car and put it above cube,
Run the game and destroy the cube while the car is on the cube.
Unity crash!

I can confirm that we have this crash as well on 5.0.1p1, and it doesn't always crash when a WheelCollider is even touching the terrain collision. Terrain modification is a pretty crucial part of our game's back-end. Is there any ETA on a fix for this? Also, would modifying terrain heights in FixedUpdate vs Update be an effective workaround for this issue?

Don't change terrain from within Update(). A better way to do that would be to have it within FixedUpdate(). A fix will come later in 5.x.

Yep, the same thing happens to me. The vehicle just drives through the raised terrain like it's not even there, without falling through it, then Unity crashes.
