2010 audi a5 - the steering wheel shakes violently causing car to shift from lanes and drive to lose control. the vehicle is unstable to drive due to poorly manufactured control arms and the dealer/manufacture refuses to repair the problem. the issue has been raised since purchase of the vehicle on multiple occasions to two different dealers. neither audi nor the dealerships both aware of the problem refuse to fix it despite being under warranty and demand money for repairs which should be covered under warranty and are a significant threat to driver and passenger safety. if control arms break or shaking in the steering wheel cause the vehicle to crash or go off road death or other injuries may occur. *tr
