Kerbal Space Program

All landing gears and small fixed aircraft wheels currently cause bouncing on spawning; severe enough to flip an aircraft upside down on the runway even if it was stationary and had no input yet.

If the aircraft does manage to spawn correctly and not begin bouncing uncontrollably, it usually will begin bouncing midway down the runway during takeoff. - this results in loss of control and the aircraft being destroyed.

This problem occurs with and without mods installed.
