: the contacted stated the vehicle makes noise and vibrates excessively when pressing the accelerator pedal or turning the steering wheel to the left and right. Vehicle speed does not affect the sound or vibration. The vehicle was taken to the local dealer several times for inspection. The local dealer never diagnosed the problem. So the contact took the vehicle to an independent repair shop for inspection. The mechanic found the following problems with the vehicle and noted them on a service invoice "rub marks on the left drive axle, the rear motor mount is not holding the engine solid and the engine is moving excessively on the cradle. " the independent mechanic suspects the caster or camber may be out causing outer tire wear on both the passenger and driver side tires. The independent repair shop only inspected the vehicle and they never made any repairs, as the vehicle was under warranty. The vehicle was returned to the service dealer who never diagnosed a specific problem. However, the dealer replaced the tires, struts, hubs and some undercarriage parts. The contact finally received a call from the manufacturer offering to provide the contact with a replacement vehicle. The manufacturer determined the vehicle could not be repaired because of damage to the under carriage, however the manufacturer never specified how they came to this conclusion.
