Disadvantages of the Haldex Traction system include: the vehicle has inherent front-wheel drive handling characteristics (as when engine braking, load is only applied on the front wheels, and due to the reactive nature of the Haldex system and slight lag time in the redistribution of engine power), and the Haldex LSC unit also requires additional maintenance, in the form of an oil and filter change every 60000 kilometers (whereas the Torsen is generally considered to be maintenance-free).
