NHTSA Complaint #11604788 — 2018 AUDI Q7

Audi Quattro (differential) noise is being heard while turning the car. The problem was identified to be due to different speeds between the front and rear differential, the locking effect of the center differential can differ significantly in tight bends. – unless there is a design flaw, there should be no noise coming from the differential . this is totally unheard of from any car I have owned. Problem was reported to Audi dealership and no definite solution was offered other than changing the oil for the center differential oil and checking to see if the problem goes away. if it does not, they would do further investigation. This is an Audi Quattro differential design fault that can be very dangerous if it fails on highways or under adverse weather or at high trafficked areas. I started an incident case (Reference #06217801) with Audi USA and Regional Case Manager (MR) told me that "our responsibility is to service the vehicles within the parameters of the New Vehicle Limited Warranty. This covers manufacturer’s shortcomings on parts and labor for 4 years or 50,000 miles (whichever occurs first) from the vehicle’s in-service date. Once these parameters have been exceeded, repairs do become the responsibility of the owner of the vehicle. Any diagnostic cost would be customer pay." This is why Audi has more class action law suits against them than any other auto brand. Keep in mind Audi has had more class action lawsuit (and lost) against them than any other Auto company. I have received 5 notices of Class Action lawsuit that Audi decided to settle in the last 6 years - just on one model. Needless to say, Audi (VW) puts faulty dangerous products on the road, hoping NHTSA has no appetite to go after them.
