POWER TRAIN
Was told that the rear differential was defective and needed to be replaced. After this rear differential was replaced, it still is not fixed. The problem was confirmed by the dealer. The vehicle has been inspected by the dealership and the manufacturer. No messages or warning lamps were activated. Symptoms of problems included reverberation of vehicle below the driver's seat, unable to keep the car in a straight line while driving. This only occurred when going a very low speeds.

VISIBILITY/WIPER, FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL, FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING
Component/System: Windshield washer fluid monitoring system (level sensor and warning). Observed Behavior: The system provides no advance or “low level” warning. The only alert occurs when the reservoir is completely empty, with no intermediate notification of low fluid. Failure Mode / Functional Impact: Washer function is lost suddenly without prior warning. The driver is not given an opportunity to refill fluid before the system becomes non-functional. Safety Risk: Loss of washer fluid prevents clearing road spray, salt, or debris from the windshield, causing immediate degradation of forward visibility. This is most critical during highway driving, winter conditions, and repeated washer use. The absence of advance warning creates a foreseeable risk of reduced visibility while operating the vehicle. ADAS Impact: The vehicle uses a forward-facing camera behind the windshield for driver assistance features. When the windshield becomes contaminated and cannot be cleaned due to depleted washer fluid, camera visibility may be impaired. This may reduce performance or temporarily disable features such as lane keeping, lane departure warning, and traffic sign recognition, resulting in simultaneous degradation of driver visibility and certain assistance systems. Reproduction / Confirmation: An authorized Audi dealer confirmed this behavior as normal and consistent with design. Audi customer care supported this position. Inspection History: The vehicle has been inspected by an authorized Audi dealer. No inspection by police or insurance representatives. Warnings Prior to Failure: No warnings, messages, or symptoms appear prior to complete depletion. The only alert occurs when the system is empty. Requested Evaluation: Evaluation is requested as to whether this design adequately supports driver visibility and safe operation, and whether any modification exists or is planned to provide earlier warning.

ELECTRICAL SYSTEM
My vehicle was excluded from Recall 25V20100/90VC; however, in early March 2025, it experienced the exact defect described in that recall: a complete failure of the instrument panel module. I paid $3,737.07 for the repair just weeks before the official recall began in late March 2025. I submitted a reimbursement claim to Audi of America under 49 CFR §573 and §577, including the paid invoice and all relevant documentation. Audi has since denied my claim. I am requesting your help to determine why my VIN was excluded from the known safety defect population. If my vehicle was not included, it suggests the recall may have been under-inclusive.

FORWARD COLLISION AVOIDANCE: ADAPTIVE CRUISE CONTROL
The car has traffic sign recognition and uses it for "predictive control" where the vehicle will read traffic signs and adjust the adaptive cruise control setting to based on road signs. It had previously been working well but a software update was recently performed under TSB 2074688/3 on November 6th, 2025 and problems have shown up. Specifically, the system is incorrectly reading signs and sometimes appearing to make signs up out of nowhere. This has resulted in the car slowing down quickly on highways and nearly causing a couple of rear-end collisions due to the unexpected and erratic braking at highway speeds. The car will be going back to the dealer to be looked at, however this is unsafe because other drivers aren't prepared for a car randomly slowing down in front of them while on the highway for no reason. The car is also available to be inspected if needed. The issues first appeared within a week of having the TSB performed and has happened a number of times since. The following incidents have occurred: * Once on Highway 10 heading North/West between Big Lake and Elk River MN; the car was set to 60mph and hallucinated a 15mph speed limit sign. There was no speed limit sign on the road at all when this happened. This resulted in a near rear-end collision with the car behind. * Two times while on Highway 35E Southbound in the Minneapolis/St. Paul metro: 60mph to 40mph on clear roads. Once resulted in a near rear-end collision with the car behind. * Two times while on Highway 35E Northbound in the Minneapolis/St. Paul metro: 60mph to 40mph on clear roads * Once on Highway 35W Northbound in the Minneapolis/St. Paul metro: 60mph to 40mph on clear roads This software update is dangerous and should be updated or recalled, especially since the car did not have any issues of the sort prior to the update being performed.

TIRES:SIDEWALL
Entered a roundabout at perhaps 15mph. RR tire hits small area on rounded curbing where a small piece of concrete curbing (perhaps 3” wide by 8” high) had come out. Tire made contact with this area. Sidewall blew out. Had to have car towed and new tire installed. Over $400. I contacted Continental USA and opened a case. They said there was nothing they could do. Suggested I have the tire dealer call them. Discount Tire, who took pictures of the sidewall issue, call Continental referencing my case. Continental told Discount Tire that they were unwilling to help. I have seen others reporting similar sidewall blowout issues on this tire. I am thankful I wasn’t traveling any faster. At the time of this incident, the 2026 Audi A6 Allroad had only sixty (60) miles on it!

ELECTRICAL SYSTEM
The Virtual Cockpit of the car (electronic screen right in front of the driver that displays speed, etc.) randomly turns off during driving, reboots, and displays an error message "Instrument Cluster Malfunction". A loud tone then chimes. This malfunction, while brief, is a safety issue due to the lack of speed information while driving.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, BACK OVER PREVENTION: WARNINGS
The car does a hard braking when reversing into fairly tight parking space . Due to the over sensitivity of Audi Pre Sense feature the car brakes hard even though there is no close by object at risk of being hit . I have taken the car for the dealer and they acknowledge that the hard braking initiated by Audi Pre Sense is a feature and not a bug . One can see many threads in Reddit reporting this problem .

ENGINE, POWER TRAIN
The alternator and starter of this car fails under heavy load due to the combined start stop engine function with heavy stop and go traffic. This is a known service problem affecting many Audis. my experience happened when I was driving home from work in heavy stop and go traffic after about 30 minutes of start and stop of the engine under these conditions the engine shut down completely and indicated a warning in the dash with an electrical system malfunction. I turned the car off and turned it back on and tried to put it into drive and shifted between park and drive and the engine still would not start. I ended up having to wait for about five minutes with the engine shut off at that point. I turned the engine back on and was able to put the car into drive. This was a dangerous situation because of heavy traffic surrounding my car and not being able to move the vehicle as it was stopped in the middle of the road. Audi has begun a service campaign for this known failure, but it should be upgraded to a recall as this is a serious safety hazard.

ELECTRICAL SYSTEM
Notice of electronic failure on dash, then car notified me to pull over safely due to the failure after 20 min of driving. Car stopped shifting gears and electronic power steering failed while the vehicle was moving. Difficult to maneuver the car to safety once the Safely Pull Over light came on. 28,680 miles on the vehicle. Dealer stated the problem is the starter generator.

POWER TRAIN, ENGINE
At a highway speed of 50 MPH the transmission completely disengaged. I was driving on a busy highway with no shoulder. The vehicle continued to coast until I was forced to stop in an unsafe location. I placed the car in park, then in drive, and it was still disengaged. I needed to turn the car off, turn it on and it drove normally. Before I was able to bring it into Audi it occurred a second time on a bridge. I needed to perform the same steps (park, turn off, turn on) to begin driving again. Audi 'repaired' the vehicle. One month later it happened again. A service report cited this as a known issue. It created a significant risk to safety considering all events occurred at highway speed with no warning.

ELECTRICAL SYSTEM, FUEL/PROPULSION SYSTEM
The car's fuel guage has been inaccurate since the initial purchase. It would always hang at around 50% and then drop to 5% within 10 miles. Thankfully, we are aware and just check the miles driven so we do not get stranded. Requested fix by dealership, they said there was nothing wrong. The recall for my car appeared and I asked for a fix, they said it's not available yet. It's been 6 months and there's still no fix for this. It would also have random computer issues such as screen shutdowns, and "take to dealership warnings" after the 1st 10k checkup. Had to bring back to the dealership, they replaced the entire computer. Seems to be fine, except a couple restarts. Back left seat is also damaged and would not lock into the upright position. Have not gone to dealership to fix yet as it will take time to buy parts and this is my only car.

FORWARD COLLISION AVOIDANCE: AUTOMATIC EMERGENCY BRAKING, FORWARD COLLISION AVOIDANCE: WARNINGS
Today, I was in a protected left turn lane prior to making the turn. When oncoming traffic (4 lanes) cleared, I gently pressed the gas pedal to start the turn, but a red “pre-sense” error triggered and slammed on the brakes. I moved my foot to the brake and then back to the gas, and the error cleared, allowing me to continue the turn. This was dangerous as I could have stopped in front of oncoming traffic or been rear-ended by the car behind me. This is the first time I’ve had pre-sense braking engage, though I’ve gotten error messages while traveling at ~50mph in heavy traffic that’s it’s about to kick in. Several weeks ago, I made an appointment at my dealership to have the error messages looked at, but the first available appointment was about a month out, so I haven’t been able to take it in yet. In today’s incident, there was no warning before the braking engaged. I’m supportive of safety measures, but I am now scared of driving my car - I would rather have none of the fancy safety features than have false positives that put me in danger. This is like the Boeing 737 Max issue - why are cars with these issues allowed to be on the road??? Please make Audi fix this urgently, as message boards suggest it’s been an issue for at least five years!

STRUCTURE:BODY
DOORS MUST BE FORCEFULLY CLOSED IN ORDER TO FULLY LOCK. FREQUENTLY THE DOORS (ANY OF THE 4 ON THE CAR) DO NOT CLOSE UPON VEHICLE ENTRY. NO WARNING THAT THE DOOR IS NOT CLOSED IS PROVIDED BY THE VEHICLE. I HAVE DRIVEN MANY MILES WITH THIS UNSAFE CONDITION, ONLY TO DISCOVER THAT THE DOOR WAS NOT FULLY LATCHED UPON MY ARRIVAL AT MY DESTINATION. THE REAR HATCH ON THIS CAR ALSO SPONTANEOUSLY CLOSED DOWN ON ME WHEN I WAS LOADING PACKAGES INTO THE CARGO AREA. THE CAR IS EQUIPPED WITH HANDS-FREE HATCH OPENING WHICH ERRONEOUSLY INTERPRETED MY MOVEMENT WHILE LOADING THE PACKAGES AS A COMMAND TO CLOSE THE HATCH. THE SENSOR IS UNDER THE REAR BUMPER, CENTERED RIGHT WHERE ONE WOULD STAND WHILE LOADING THE CAR.
