NHTSA Complaint #11552316 — 2018 AUDI Q5

Hello, On September 29, 2023 while I was driving my 2018 Audi Q5 a light come out "Steering malfunction! Please stop vehicle". I called the Dealer Audi Arrowhead in Peoria, Arizona, and schedule an appointment for October3, 2023 to do a diagnose. I drove the car throughout these days and I have not notice anything wrong with the car, except that light. I went to the dealer they proceed the diagnosis, gave me the code C101C07, and the quote to do steering gear replacement. I asked them: if the car is drivable, is just that light on the dashboard, why you can not do a software update? Because they refused to do that, I called Audi USA, and after a few days of back and forth communication they refused to do the software update and agreed to participate with the repairs and cover 50% of the repair cost. I pick up the car from Audi Arrowhead (they did not provide a print out result for diagnosis, also no bill for diagnosis) and I called Audi Scottsdale and because they confirmed me that they can do a software update I decided to bring the car in their shop and have again a diagnosis done. The same code was founded and of course they refused to give me a print out result, and I got charged $210. Even they admit the car does not show sign of something broken, telling me that it is possible that it will never show signs of failure they refused to do the software update. Because it doesn't make sense to me that the car runs perfectly, as always, only the light is on in the dashboard, I ask you to help me and intervene by asking Audi to issue a bulletin to update the software on my 2018 Audi Q5. Thank you in advance!!!
