NHTSA Complaint #11496814 — 2016 AUDI A6

The electronic steering control module failed while the vehicle was stopped. A light came on the dash which stated something like ~"Do Not Drive Major Steering Malfunction" and the steering became almost impossible to turn. The vehicle was towed to an Audi Dealer and repaired at my significant cost. I am suspicious that there is a known defect which has not been acknowledged by Audi. I also own a 2014 Audi Q5 which I received a letter to extend the warranty for this specific issue (see uploaded information). The cover letter states this applies to Certain 2011-2016 Model Year Audi B8 (Q5) and C7 (A6) & D4 Vehicles. I contacted Audi Customer Care and they were unwilling to tell me any distinguishing attributes for why some 2016 A6 vehicles are included and my 2016 A6 is not. Audi told me that the VINs, PNs, Date of Manufacturer for covered vehicles is proprietary. My A6 has been babied and has never been in an accident or experienced any pothole or similar trauma, yet I had a major steering failure at ~48000 miles 6 months beyond my warranty period. And there is apparently a known defect in other similar Audi vehicles. Audi was very reluctant to discuss this issue with me and told me there is nothing I can do about it. As a minimum, I deserve an explanation on why my A6 with a known steering system defect in similar vehicles is not addressed in their safety and warranty campaign.
