I was building a model based on my son's Lego car. It has a very basic suspension using wheels mounted to the bottom of L brackets and a shock mounted inboard the main body. As soon as I load the model the springs begin to push the arms down until they break and explode.

Edit 1: I've found that this bug only happens on some runways.

Avalanche:

Gold Prix Raceway:

Bandit:

Edit 2: If I add all the springs back it happens at all locations.
