2020 AUDI A6

Water intrusion in passenger floor board which causes problem with control module and reduces acceleration

Audi issued a recall for our vehicle’s fuel level sender which reports the amount of fuel in the tank to our fuel gauge display in late 2022 or early 2023. The reason for the recall stems from a safety issue in which the car incorrectly can display that there is more fuel in the tank than what is actually there. Our local dealership’s service center, Princeton Audi initially completed this recall repair in Late February or Early March of 2023 while the car had roughly 25-26,000 miles on it. Less than a fews days later, the recall repair failed and our car shutdown on us leaving my wife stranded while I was having surgery unable to help her. I escalated and reported this issue to Audi of America immediately to create awareness as this was dangerous. The Princeton Audi Service Center attempted to repair the recall a second time and assured us the repair was successful. The same issue has unfortunately resurfaced less than a year later, in February of 2024 while the vehicle has only 33,398 miles on it. After a third attempt to repair this recall, the Princeton Audi Service advisor confirmed the fuel level sensor was again faulty. Regretfully we are still seeing inaccurate reporting of the fuel levels in our car creating a perpetually dangerous situation for myself, my family, and others on the road. Our car can shutdown on a major highway if it runs out of gas because the fuel gauge display keeps showing we might have half a tank or more due to the inaccurate reporting from the fuel level sender. After contacting Audi of America again about this failed recall, they seem to be dodging responsibility for the failed remedy and providing no recourse to ensure the safety of myself, my family, or those we out at risk if we keep driving this vehicle. The Princeton Audi Service center keeps stating they have made the repair, but the recall remedy keeps failing for us. Please help us as they refuse to replace the vehicle or buy it back after the failed recall.

Experienced alternator / generator failure while driving. Various vehicle systems starting shutting down and warning symbols were displayed. Vehicle stopped running on the highway and needed to be towed to the local Audi dealership. The sequence / progression of failure occurred over several miles with complete vehicle shutdown and stop in the middle of a busy highway intersection. Dealer confirmed it was an alternator / generator failure and it needed to be replaced. Seems to be a common occurrence with the A6 model. Dealer informed me it could be a couple of weeks to a couple of months for a repair as this item is on back order with Audi. Audi should issue an immediate recall or warning of this failure.

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.

The rear view camera on the vehicle stops working intermittently. I have provided photographs of this to the Dealer. Their scanning of fault codes noted that the "right environmental camera faulty B127D04: Rear environmental camera faulty." The ticket also notes they found multiple sporadic faults for B127F04. Although they have admitted to finding faults with the camera, they refuse to fix this because they could not duplicate the exact behavior at the time it was in their shop. By definition, this is an intermittent issue. Audi had other model years recalled for this same issue. I believe this is a serious safety threat as one can't see things behind you and a person or vehicle could be hit. Audi is aware of this issue and is refusing to repair it under warranty.

The car literally stopped working while driving. All electrical components shut down. Unable to put the car into neutral to push it to safety. Had a hard time getting the vehicle towed because the parking break engaged somehow and we were unable to disengage it. Hazard lights did not work at all! Extremely unsafe situation to be in, especially if on a highway or expressway with vehicles traveling nearby at high speeds.

Electrical system malfunction. Car will not run

Receiving multiple electrical warnings including low battery charge, vehicle starting system, parking brake malfunction, stabilization control (ESC/ABS), parking aid malfunction, and all-wheel drive malfunction. Issue appears to be due to a common failing 48v battery alternator.

I purchased the car new around June 2020 and it currently has just under 26,000 miles on it. Earlier this week while driving the car, an electrical malfunction warning appeared on the dashboard display. The first dealership I contacted did not deem it serious and set me up for an appointment over a month away. The second dealership I called had me tow the car in right away as the thought was my alternator had failed. A call back later that afternoon confirmed the alternator did in fact fail. That dealer also indicated that the wait time for a replacement was several months away. This seems to indicate much larger problems with this part as alternators are fairly common and very necessary components.
