While operating the vehicle under normal driving conditions, the vehicle suffered an immediate, un-commanded loss of engine power and throttle response. The vehicle displayed a critical dashboard restriction stating: "Maximum engine speed 2500 RPM", forcing an emergency limp-home mode that instantly created a roadway collision hazard. Simultaneously, the vehicle's primary safety and convenience systems dropped completely offline, displaying synchronized, consecutive malfunction alerts for the Central Locking...

System, Audi Pre Sense (Distance Monitoring), Cross Traffic Assist, and Lane Change/Blind Spot Warning systems. A subsequent professional diagnostic scan confirmed that the vehicle's Engine Control Unit (ECU) has hard-logged active manufacturer fault codes P310A (Low Fuel Pressure Regulation - Fuel Pressure Fluctuates) and P310B (Low Pressure Fuel Regulation - Fuel Pressure Outside Specification). These synchronized electrical and drivetrain failures occur intermittently, yet have specifically occurred multiple times following exposure to moisture, including rainfall, winter slush, and standard car washes. The identical electrical system dropouts were officially reported to two authorized Audi dealership service centers during its active warranty window, but the underlying system failures remain uncorrected, leaving a recurring safety hazard unaddressed.

Also, the door handles would not work me and my daughter had to climb out of the car windows to get out. So like, you know what? And then we had to try to access the battery compartment to do a hard reset. The vehicle is scheduled to go back to the manufacturer dealer to look at it again next week. However, I will be contacting audi u s a again. Since I told him I had all these issues, they refused to help me out in any way. This is a very big safety issue.

2019 Audi A6Electrical system

The central locking / electronic door lock system on my 2019 Audi A6 intermittently malfunctions, sometimes with a long beep sound and an error message appearing on the screen in front of my steering wheel. The affected system is available for inspection upon request. The issue does not happen all the time, but the door sometimes fails to unlock or appears to re-lock while I am trying to open it.

lot, an unstable individual was approaching the area near my car. I attempted to enter the vehicle quickly for safety, but the central locking system malfunctioned. As I tried to unlock and open the door, the vehicle appeared to lock again and the door would not open. I was temporarily locked out of the vehicle during a potentially unsafe situation. The door eventually opened only after I pushed the door inward with force, locked and unlocked the vehicle again, and tried the handle again. This created a very concerning safety risk because I could not immediately access my vehicle when I needed to get inside quickly as the individual approached me. The problem has not yet been fully reproduced or confirmed by a dealer to my knowledge. I previously mentioned the central locking issue during service and asked whether there was a recall. I was told there was no recall and that a lock replacement would cost approximately $850. The issue I have been experiencing appears consistent with Audi Technical Service Bulletin [redacted]/5, which applies to 2019 to 2024 Audi A6 models and describes central locking / door lock concerns and related fault codes. Because the defect is intermittent, it may be difficult to reproduce, but it creates a safety concern because the driver may be unable to access the vehicle when needed. I tolerated this issue for a while now, but now I realize what a big safety concern it really is and I'm surprised that a recall has not been issued.

2019 Audi A6Electrical system

Shortly after purchasing in 2025 I began having occasional issues with the door locks. Eventually the issue would self resolve but now I have experienced at least 2 times in last month being locked inside the vehicle and unable to exit without climbing into the passenger seat. I have not taken it in for repairs yet due to cost concerns but I am worried about this dangerous situation.

2020 Audi A6Electrical system

Audi A6s have had massive issues with the door actuators. There are times when you go open the passenger side doors (both front and rear) and the doors will not open as there is either an electrical, software, or device specific issue. It requires 2-3 pulls of the door latch to open the front and rear passenger doors. The issues keep appearing a month or two after the dealership supposedly fixes the issue. I have had this fixed/reviewed 4+ times between Freehold, NJ and Cherry Hill, NJ Audi dealerships. This has...

been going on since I purchased the car in early 2021. I have asked them to push this up to Audi corporate and have received no response. Audi will also not offer a lemon buyout for these door issues. I believe this needs to be heavily reviewed as if you search the Audi forum websites online, this is a constant problem for the 2018-2023 A6s.

The Audi software/MMI system has issues showing the 360 cameras in addition to the rear facing camera.

The issue will not stop until the car is parked/off. for at least an hour. This issue has been happing since I purchased the car back in early 2021 and Audi did not "lemon-out" the car. I believe this is just as dangerous as the recent backup camera recall. I have asked...

Freehold, NJ Audi and Cherry Hill, NJ Audi to review, but they said if it doesn't happen when there, they can't action. I believe this is the same software issue the backup camera has and requires a similar recall as drivers rely on the side cameras for parking and there is a risk we c an hit another object or person.

Missoula, MT. Service tech couldn't figure where the water was coming from. Finally did research to find an Audi TSB 2059792/5 with the cause and remedy. *Recently Purchased this car and later found the seat not working. The VW dealership/service found the electrical corrosion and mold. Mold was not visible until the seat was moved. Mold was extensive throughout the passenger side under the seat - spread and growing under the carpet, insulation and in the electrical well in the floor board. Pictures attached - tech write up also available upon request. No warning lights were present. ** Audi put out a TSB (Tech Service Bulletin) in 2023 and repaired the cars under warranty - assume this was a wide spread issue for a TSB to be issued and for Audi to manufacture parts to fix the problem. Mold can have serious long term consequences to anyone exposed. I believe Audi should have done a recall for safety reasons. I just bought the car on 1/10/26 used with under 40,000 miles. Carfax or other research did not turn up a recall. I have sent a letter to Audi of America detailing the problem, referencing the TSB and asking them to cover the cost of repair as they had covered the cost on vehicles under warranty. This car is just out of the 5 year warranty but has only 40,000 miles on it. No recall was issued that I can find. Any help you render would be appreciated. Mold exposure is serious if not immediate.

This is a recurring safety defect: Repeat Failure: This is the second time this specific VIN has suffered a mid-traffic alternator failure. An Audi-certified replacement was installed by an authorized dealer (Audi Arlington) in 2022 following an identical incident. That replacement part has now failed. Failure of "Service Action" (27BQ): Despite an active Service Action for this component, the vehicle was not repaired during multiple prior service visits at authorized dealerships. The manufacturer failed to proactively address the defect, leading to this second roadside emergency. Cascading Electrical Instability: This VIN has a documented history of systemic electrical and safety system failures, including a gasket failure that compromised safety electronics and a total fuel system replacement due to sensor failure. The manufacturer (Audi) has classified this sudden loss of power in traffic as "non-critical," despite the clear risk of high-speed collision and physical injury. I am requesting a formal investigation into the recurring failure of the 27BQ component and the adequacy of the manufacturer's current service remedy.
