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 - 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. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S.

The Audi pre-sense is activated by weather. I was driving during a thunderstorm and Audi presence activated causing the car to come to a hard stop due to precipitation. It happened again backing out of my driveway the Audi pre-sense was activated and the car came to a hard stop. I thought I had back into another vehicle. This is very dangerous.

The car has had multiple issues with warning lights and malfunctioning systems. Including : 1. Child locks 2. Every single component of the adas 3. Emergency services being activated at least a few times a month - this is an sos for emergency 911 service. The repeated, continuous and mostly false warning lights are a driving distraction that can easily cause an accident. I have photos of all warning lights coming on in the vehicle. The dealership has repeated stated that they couldn't reproduce the problem even though pictures were provided and the car is still under the original warranty period. The latest attempt to fix the vehicle was to replace the sensors on the front of the vehicle. This solution was only attempted after the 4th report of the problem to the dealership where the car was serviced under the original manufacturers warranty.
Received a message for "electrical system failure" and drove ok at first but began receiving failure messages for various systems including but not limited to start/stop system, transmission, power steering, and crash avoidance systems. Soon after the entertainment and comfort system screens went blank followed by the dash screen and the car eventually just turned off as I was trying to find a safe place to pull over. Safety was put a risk as I was stranded on a busy road with no shoulder and because the battery was impacted my hazard lights only lasted a short time which left me and my vehicle exposed on the side of the road. The car was towed to the dealer (Audi of albany) who inspected determined the failure was related to a faulty ignition generator. The car is currently at Audi of albany and will be for at least 2 weeks so I am assuming it would be available for inspection. Many different warning lights appeared in the short time leading to total shutdown of the car. I recall a start/stop failure message, batter charge low, transmission failure light, power steering failure warning, adaptive cruise control, frontal collision avoidance among others. As stated above all screens in the car eventually turned off and the car fully failed on a main road and required a tow to the dealer.

While driving my family on a major interstate, a myriad of warning ?? lights appeared on my dash panel and my vehicle’s steering literally locked! I have had no previous warning lights or issues with this vehicle since it was purchased. This near fatal incident happened as a 18-wheeler was seeking to merge onto the interstate and I couldn’t change lanes to allow the oncoming traffic to merge. This malfunction/failure caused me and my family to narrowly miss being fatally crushed by the merging 18-wheeler. After bringing the vehicle to a stop in a safe area off of the interstate and locating the vehicle owner’s manual, I learned that the electromechanical steering unit failed on my 2017 Audi A6 (mfg 6/16). Because all of the local Audi dealerships were closed, I had to call and have the vehicle towed to my home. Upon further researching the issue in various Audi forums, I realized this system failure was widely experienced by Audi owners and that it may have even played a part in prompting Audi to issue “electromechanical steering unit extended warranty” letters to certain Audi 2011-2016 vehicle owners (a6 owners included). I believe NHTSA should do its due diligence in seeking to reduce highway safety fatalities on our nations highways caused by vehicle safety defects/malfunctions by auto manufacturers and execute a mandate for Audi to (1) issue a safety recall for this issue, or (2) extend the electromechanical steering unit warranty to include later model year vehicles. It appears that Audi has not corrected the known issue on their own; thereby warranting nhtsas regulatory intervention. I would like NHTSA to launch a defects/safety investigation to determine how many more Audi owners are at risk of experiencing this life-threatening, correctable, and known issue. Please keep me informed on the results of my report.

I was driving on the interstate when the vehicle gave a warning saying "electrical system malfunction, contact dealership". I went to the dealership as I was within a couple of miles and they said it could be many things and they would need to evaluate it the following week. I left with the car and attempted to drive it back the following week on the scheduled appointment. The vehicle did not make it back to the dealership. While driving on the interstate back to the dealership, a message saying, "electrical system failure, safely exit roadway" came on. I was able to exit off the interstate immediately into a parking lot. While I was trying to exit, multiple warning lights came on saying the crash sensors were inoperable, transmission was inoperable, camera system was inoperable, and the car started shaking as if the engine was loose under the hood and it shut off and would not restart. This took less than about 90 seconds as I was at an exit and already in the right lane on the interstate. Audi care came and towed the vehicle and the dealer says the alternator has gone bad and it is on backorder. This is exceptionally dangerous because if I were not at an exit and in heavy traffic, this could have happened while I was in the middle of the interstate and the vehicle lost all power. I've since read Audi forum and found this exact scenario has happened to many drivers who were not as lucky to be near an exit or under warranty. Audi should recall the vehicle because it puts the driver in a very dangerous situation. I was stuck in an empty parking lot for several hours waiting for a tow but I consider myself lucky after reading the experience of other drivers. My car has been in the shop for three weeks now and I'm not sure when they will have it fixed. My warranty expires in the next few months so I may end up having to pay for repairs later because my warranty expired while the car sits at the dealer and I won't be able to test if it has been resolved.
Multiple warnings indicating to contact dealer (lane departure, adaptive cruise control, collision avoidance, etc) then 1 minute later transmission failure and engine failure imminent. . . . Pull over immediately and contact dealer. I turned into a road off main highway within a minute of the last two warnings and as I turned, my center mmi went blank then my electronic dash went blank, transmission went into neutral and the engine died all within a few seconds. Fortunately I was able to coast to a stop in the parking lot.
The Audi presense system works intermittently. While under warranty I told the dealer the system wasn't working and they claimed that I must have hit something and would have to pay approximately $4,000 to realign the system. I refused to pay to realign/adjust the system since it was under warranty. I contacted the Audi customer advocate department who said they rely on the dealer to identify the issue and fix it, and since they said it may be related to an impact they could not do anything. I continued to drive the car and in the midst of a summer downpour sometime in 2022 the system corrected itself. I once again told the dealer what happened however they said there was nothing for them to diagnose. The system worked as should until October 2022 when it started to show a message saying system malfunction. I followed the car manual recommendation and washed all of the sensors however that did not solve the issue. I once again spoke with the dealer who said often times there's a moisture buildup in the location of the windshield mounted sensors. There's no way to get to the sensor and I asked them to clean it under warranty. The dealership once again refused to address the issue. I once again called the customer advocate department at Audi USA however they refused because I have just exceeded the 50,000 mile warranty. I noted that the issue has been ongoing and Audi never solved the issue. I purchased the auto because of the safety features it came equipped with. I'm asking them to resolve the original issue as identified while under warranty.

August 25, 2020 traveling wb on I-90 [mass turnpike] passing and 18 wheel tractor trailer with an unmarked white box trailer. Truck 'weaved' to the left into my driving lane as I was overtaking it. I swerved to the left to avoid contact of my 2019 Audi A6 premium plus at about the a pillar and the rear wheel area of the box trailer. In my evasive action the car's lane keeping assistant activated as I was about to cross the lines on my left side to avoid the truck, the car took control of the steering and aggressively steering the car back at the tractor trailer. I braked the car as hard I could to avoid collision with the box trailer. None of the collision warning system activated and the car's sensors and cameras did not recognize that I was trying to avoid a high speed collision with the tractor trailer. I brought the car to the dealership [Audi albany, latham NY] after return from my trip to have safety systems checked. No fault codes were detected.
