Excessive wheel hop occurs frequently under mild to heavy acceleration. In wet conditions, it happens much more frequently and can cause serious traction and handling problems. This also puts heavy stress on the drivetrain and has caused many failures in half-shafts and differentials amongst other owners vehicles, which could lead to further catastophic loss of control. This is a major issue that is being ignored by the manufacturer at this point in time.
