AUDI Complaints

Engine shuts off occasionally whilst cornering at very low speed. No warning. Been happening for several years.

We are submitting this formal complaint regarding a recurring and unresolved issue with the HVAC (air conditioning) system in our 2024 Audi Q3 Quattro S Line. Since February 2024, we have consistently experienced failures in the climate control system, particularly after exposure to rainy conditions. Specifically: 1. The front air vents begin blowing warm air at random intervals, even when set to cool. 2. The rear vents completely shut off airflow during these instances. 3. This occurs most frequently during or after rain but now occurs in dry weather as well. We believe this issue compromises the safety and comfort of the vehicle's cabin environment. The manufacturer, Audi (Volkswagen Group of America), asserts this behavior is normal per FMVSS 103 regulations and the "cabin capacity requirements" of the Q3. Specifically stated in Audi Corp. email from March 6, 2025: “From the NHTSA homepage using the search bar>search FMVSS>Select NHTSA Statutes, Regulations, Authorities and FMVSS>Select FVMSS under Federal Motor Vehicle Safety Standards>Scroll down or utilize the table of contents to locate 571.103. Dimensions for the interior cargo space in your 2024 Audi Q3. - Headroom (Front/Rear): 39.6/37.6 in., Legroom (Front/Rear) 40/36.1 in., Cargo volume behind first row: 48 cu.-ft., Cargo volume behind second row: 23.7 cu.-ft” However, a review of FMVSS 103 (Windshield Defrosting and Defogging Systems) reveals no explicit requirement that mandates the rear vents be disabled during humidity control. Additionally, no documentation has been provided by Audi to substantiate this claim. This issue potentially violates FMVSS 103's intent, which is to ensure adequate visibility and cabin comfort. With passengers, especially children, experiencing unacceptable conditions in the rear seat, we urge the NHTSA to investigate whether: The behavior described is part of a broader defect pattern, 2. Audi's HVAC system logic conflicts with FMVSS standards or consumer safety expectations.

being quality Engineer, why is this thing failing , and why are there no recalls? Amazing how they design these things to fail right at 50k miles. From what I hear, the audi's are notorious for not making these replacements simple and specialized tools are needed. I wouldn't change anything engine related unless you have issues like engine shaking, or rattling sounds stemming from the engine mounts. And if you get major work done, it is probably best to go to the dealers and pay the extra to make sure it will be taken care of properly! numerous same issues engine mounts after 50k MIles

The monitor in my vehicle will randomly stop working. This could affect the backup camera or other vehicle systems. It also causes a problem with setting the user, and this controls my settings in the vehicle.

The MMI in the car constantly reboots. Started occasionally doing it once a drive, would restart and then go right back to what I was at. Then it would restart multiple times a trip, not going where I was at. If I had music on it would lower the volume it was rebooted to or go to a different song. The screen would also freeze for a few minutes after in being rebooted. Took it to Audi, they installed an “update” now it reboots every 3-5 minutes, causing serious safety concerns with no access to the MMI stystem.

First Incident [XXX], in Columbia SC driving in parking lot On Post, approx 10pm, blocking traffic. Car shut down and MMI disappeared. After approximately 20-30 minutes car started, still no screen. I was able to drive it. Next day, Rebooted per Google, took to dealership who said I should make sure I used premium gas. When I said I did I was told to be careful which gas station I bought it from. And since the screen was back up they couldn’t do anything. I called the Corporate office who had them run a full systems check. All with MMI was well until [XXX] at [XXX]pm. Driving in Columbia SC screen disappeared again but car did not stop this time. I called dealership who told me to press the volume button until it rebooted. It didn’t work. I was told to bring it in. The Audi App sent me a Headlight Assistant Malfunction Warning! message at 7:44pm also, same evening as the MMI incident. Copy of current screen and 10/24 service receipt. This is a dangerous situation as someone almost hit the back of my car during the first incident since the stop was so sudden ([XXX]) I was blocking the driveway and cars had to backup and detour in a small dark area. Losing MMI while driving is a distraction. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Multiple owners as well as mine MMI system just randomly rebooted multiple times when I was driving on the interstate. The speed goes up to 70MPH and I lost my maps and everything.

The MMI constantly reboots every 3-10 minutes every trip. Each time the system reboots, it requires me to interface with it to get it logged back in. The MMI is also the main interface with the navigation system, which restarts as part of the reboot, requiring me to restart the route while driving. Recently, it occurred while driving in downtown Boston, nearing my destination, which required several quick turns, ended up having to back track once the MMI came back on.

The contact owns a 2018 Audi Q5. The contact stated that while pulling into a business at an undisclosed speed, there was an unknown warning light illuminated, and the message "Left and Right Rear Signal and Center Rear Brake Light Malfunction" was displayed. Additionally, the contact stated that the key warning light and engine malfunction warning lights were illuminated. The vehicle was taken to a dealer where it was determined that there was water intrusion into the rear cargo area of the vehicle, due to a clogged drain. The contact was informed that the drain tube needed to be cleaned, the module needed to be replaced, and the vehicle needed to be rewired. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 83,000.

The MMI unit randomly reboots and disconnects anything connected for navigation. It does this very often, every single time I drive. In a 30 min drive, it could reboot at least 3 times and make you sign in as a user to access it.
