FUEL/PROPULSION SYSTEM
There is a recall out for “2016 Audi A6 vehicles” the recalls are “fuel system rail” as well as “coolant pump”. Both recalls are vin specific and what I find to be devastating is that both recall risk pertains to possible fire! I have the exact issues with my vehicle I even have the epc light coming on and the code is “fuel rail system” I also have an ongoing issue with my coolant system. I have documentation that I’ve paid out of pocket to take care of these issues, however being that there is no current open recalls under my vin number I do not believe mechanics know exactly what to do to fix the issues. The vehicle is misfiring, shutting off and the EPC code is stating “fuel system rail” along with the coolant leaking. I have a [XXX] daughter and to be such an expensive vehicle, I thought I would feel safe and valued. I’ve worked as a service BDC manager for years and at other dealerships when a situation like this would occur, we still wanted them to bring the vehicle into the dealership and if it was in fact relatable to the recall we would take care of it, regardless to it being “vin specific”. There is a such thing as “silent recall”. I really hope that you all can take this as an emergency case and help with such terrible situation. Thank you so much.

FUEL/PROPULSION SYSTEM

NHTSA complaint #11723814 — an unverified report by a vehicle owner.
FUEL/PROPULSION SYSTEM
I own a 2016 Audi A6 3.0T. After filling the fuel tank completely, the vehicle only traveled approximately 190–200 miles before the fuel gauge indicated empty. This represents a sudden and significant loss of fuel range compared to normal operation. There are no warning lights, check engine lights, fuel smells, visible leaks, rough idle, or abnormal noises. The vehicle operates normally otherwise. The issue appears to involve excessive fuel consumption or incorrect fuel management without any driver warning. This condition poses a potential safety risk because the vehicle may unexpectedly run out of fuel while driving, which could result in loss of power in traffic or on highways, increasing the risk of an accident. The issue has been observed repeatedly after refueling. At the time of this report, the vehicle has not yet been inspected by a dealer or independent repair facility, but diagnostic evaluation is planned. Based on owner research and symptoms, the issue may be related to a fuel system, engine management, or emissions-related component malfunction that does not trigger a warning indicator. No prior warning messages or lamps were displayed before or during the occurrence.

FUEL/PROPULSION SYSTEM
I purchased a 2014 Audi A6 2.0T Quattro premium plus on November 15, 2024 with 99,141 miles. I got the 14 day dealership extended warranty, which covered powertrain systems. After 3 days of driving exactly 103 miles the oil light came on my dashboard telling me that the oil was low. I immediately brought it back to the dealership and their mechanic look at it, he said there was nothing wrong and changed the oil so it should be good now. I drove it another 3 days 136 miles this time, and the oil light came on once again. Brought it back a 2nd time to the dealership’s mechanic. After about a week, we heard back and they told us he still couldn’t find anything wrong, but agreed that for some reason, the engine is consuming oil more than it should be. At this point we go to an actual Audi dealership where they tell us that the pistons and turbo were the problem so they would have to rip apart the engine and seal everything back up. At the time we purchased the vehicle on top of the 14 day dealership warranty we also purchased an extended warranty by a company called integrity warranty LLC. Our warranty company decided that they were not going to cover the cost of the parts and labor in order to fix my Audi, because they said it was a pre-existing issue prior to us purchasing the vehicle which we had not heard of before, or even seen on the Carfax report. On February 25 I was driving at night 25 mph and I came to a red light stopped my car and began smelling a very strange smell. Saw a lot of smoke coming from the exhaust in the back, the dashboard lights began flickering, the steering wheel start to shake, and then the car just shut down. Now I am without a vehicle, the dealership will not help us, the warranty company will not help us, and I now have to purchase a new car while still making payments on the Audi that doesn’t work.

FUEL/PROPULSION SYSTEM
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.

FUEL/PROPULSION SYSTEM
P2067 engine check code which shows faulty fuel sensor. Audi has recalled other year Audi a6 sedan vehicles with the same issue and this seems to be a safety issue as it can show incorrect fuel gauge and in the event of car out of fuel, engine can stall and can cause accident.

FUEL/PROPULSION SYSTEM
Good morning, For the past couple of weeks, I've been getting the run around on whether the issue I'm having with my vehicle is an active recall. I recently took my vehicle to Eurocode Tuning (Torrance, CA), and the mechanic instructed me to take my vehicle to the dealer because the issue I am currently experiencing (fuel leak in the injection system) is listed as a recall. I contacted the Audi dealership in Long Beach CA via phone at (562)610-4000, the service representative stated that he found no active recall on my vehicle. Once again contacted Eurocode Tuning and they stated to have them run a diagnostic on the vehicle and they will see its the fuel leak in the injection system. And they are required by law to fix the recall. The following morning I took my vehicle into McKenna Audi ( Norwalk, CA) and one of the service representatives reiterates that my vehicle has no active recall. I stated that I was well aware of that, however, the issue I was having was listed as a recall on the web and I was informed by the repair shop as well. I proceeded to show him the information I got offline and my failed smog that was done on my vehicle. He proceeded to show me the breakdown on his computer that it was no active recall and the only thing that they were looking into was issues regarding the turbo. He stated what I was talking about was an extended warranty and my vehicle is well past that warrant. He then proceeded to say if a diagnostic is done on my vehicle I will be responsible to pay it and any repair done on my vehicle. So I walked out and decided to contact you. I am just trying to determine whether my vehicle could be repaired under the recall. I'm extremely frustrated and concerned for my safety because the recall did state the risk of a fire. Sincerely a confused, frustrated Audi owner [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

FUEL/PROPULSION SYSTEM
The Alternator had failed along with the battery and shut off the car, rendering it useless on the road. The vehicle is still under the New Car Warranty. It was a hazard as it could not be put into neutral and was stuck in park. The dealer had confirmed it was a manufacturer-wide problem with waits of up to 3-6 months for the part. The tow truck had difficulty towing it up as the car was not able to roll. Before the car shut off immediately it had given the warning "Electrical System: Malfunction! Please Contact Service, as well as Auto Start Stop System: Malfunction!".

FUEL/PROPULSION SYSTEM
The EPC light came on in my vehicle and I noticed I started to lose gas faster than normal. Took it to a shop to get diagnosed, they stated that my vehicle was under a recall (Recall #24DP). I called Audi and they said I do not fall under the warranty even though the website said 2016-2018 Audi A6 were under recall. They would not provide any help for me. My vehicle is showing all the signs of the recall. Sometimes the car will accelerate too fast and it is a risk for not only other drivers but me as well. It is just ironic that the same same problem for that recall is happening to my vehicle.

FUEL SYSTEM, GASOLINE
The contact owns a 2012 Audi A6. The contact stated while pulling out of the driveway, he smelled an abnormal fuel odor. The contact stated that the fuel odor became stronger while driving 65 MPH. There was no warning light illuminated. The contact stated that he pulled into a parking lot and opened the hood. The contact stated that he noticed that the fuel odor was coming from the engine. The vehicle was towed to an independent mechanic, where the check engine warning light illuminated. The mechanic determined that the check engine warning light had illuminated due to low pressure on the fuel rail, and the contact was informed that the supercharger needed to be removed for a more thorough inspection of the vehicle. The dealer was notified of the failure and informed the contact that the VIN was not included in a recall. The vehicle was not diagnosed nor repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in NHTSA Campaign Number: 15V019000 (Fuel System, Gasoline). The manufacturer referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 102,000.

FUEL/PROPULSION SYSTEM
My Audi A6 is experiencing symptoms of a documented and open recall at Audi, and Audi USA and the dealer are refusing to even evaluate the vehicle for recall status. The recall is a rollover valve nipple, with age and stress cracking can develop on the plastic fuel tank, causing a leak to occur. My car is experiencing just such a symptom, and has been confirmed by two independent mechanics.

FUEL SYSTEM, GASOLINE
The contact owns a 2016 Audi A6. The contact stated that while refueling, the gas nozzle would frequently stop, causing gasoline to leak from the vehicle. The vehicle was taken to a dealer where it was discovered that the fuel tank sensor needed to be moved to another location on the vehicle. The contact was provided an estimate for the repair; however, the contact declined to seek a second opinion. The contact was assured by the dealer that the vehicle was safe to be driven. A few days after leaving the dealer, the vehicle stalled while driving at a slow speed, with the check engine warning light illuminated. Due to the failure, the vehicle was towed back to the dealer who discovered that fuel had filled up in the evaporation canister sensor which caused the fuel tank and the fuel pump to become defective. The manufacturer was notified of the failure but informed him that his vehicle was not under recall or warranty. The vehicle had yet to be repaired and remained in the possession of the dealer. The failure mileage was approximately 48,000.
