WAU35CFN1TN0134612026 AUDI A6quattro Prestige

We are reporting serious safety-related faults involving my leased 2026 Audi A6, VIN [XXX] , and a same-model 2026 Audi A6 loaner provided by Audi Central Houston. Core safety issues: 1. My vehicle previously displayed a Park/rollaway warning indicating Park could not be engaged. 2. My vehicle has had repeated starting-system faults, including: “Engine start system: malfunction! Please contact Service.” 3. Our vehicle has been the subject of multiple repair visits at Audi Central Houston and is currently at the dealer, available for inspection. 4. After the third repair order, Audi Central Houston represented the vehicle was ready for pickup. Before we accepted return, the same starting-system malfunction reportedly recurred during Audi’s own test-drive/verification process. Audi added that April 30 recurrence to the still-open third repair order. 5. While our A6 remained at the dealer, Audi Central Houston provided a same-model 2026 Audi A6 loaner. That loaner displayed: “P not possible. Risk of rolling away! Please contact Service.” A photo is available. 6. Because the loaner warning stated Park was not possible and there was a risk of rolling away, we did not leave it parked unattended and returned it directly to Audi Central Houston. The apparent failed/malfunctioning systems involve Park engagement, electronic shift-by-wire, transmission control, parking interlock, starting-system control, electrical modules, software, gateway communication, or related safety-critical controls. Safety is at risk because a vehicle that cannot reliably engage Park may roll away and injure occupants, pedestrians, bystanders, or service personnel. Audi Central Houston has inspected/serviced vehicle. Audi of America/VW Group has been notified under Audi Case No. XXX. We request NHTSA investigate whether 2026 Audi A6 vehicles have a safety defect involving Park engagement, rollaway risk, starting-system malfunction, transmission/electronic controls, software, INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While driving yesterday, the MMI reset and included the dashboard. The dash completely froze for a couple minutes(including the speedometer), and then the whole system blacked out and restarted. There has been a check engine light on since I got the car in December. Havent been able to get a service appointment with a loaner. Also since new, adaptive cruise control works intermittently with a warning that a door is open(when all doors are completely closed).

I own a new 2026 Audi A6 Prestige that I just purchased and have 320 miles on so far. The vehicle is experiencing a driver assistance system malfunction. The instrument cluster repeatedly displays “Driver assistance: limited,” along with warnings that Lane Assist and High Beam Assist are unavailable. The warning messages and audible chimes occur repeatedly while driving, approximately every few seconds or minutes. The alerts and beeping repeatedly interrupt driving and create a distraction that takes the driver’s attention away from the road. This is a big safety issue. The vehicle has been taken to an authorized Audi dealership. The dealer confirmed the issue but advised that the fix is a software update that has not yet been released by the manufacturer. Because the update is not yet available, the vehicle continues to operate with driver assistance safety systems disabled and with repeated warning alerts occurring during normal driving. The concern is that the repeated alerts and chimes during driving create a driver distraction and affect safe operation of the vehicle. The manufacturer has indicated a software update may be released in the future, but there is currently no repair available. This is a safety concern as it constantly takes me away from driving and looking at the constant alerts and beeps. These includes items such as: - alerts repeat while driving - driver-assistance safety systems unavailable - warning tones and pop-ups repeatedly distract the driver I do not blame the dealership as they have done everything they can do, but how can Audi not make this a top priority to be fixed. I am told that this is impacting almost all new Audi cars including the A5 and A6s. Thanks for your help.
