general problems of the 2019 Audi A6 - part 2

Known generator problem. The entire car shut down when I was on the express way at 5:30 pm rush hour in chicago. Luckily I was able to get over to a shoulder before the car went completely dead . Even the emergency flasher would not work, miracle that we didn't get killed. Can't believe Audi let people drive these cars when many have had this problem.

Was driving down the road and received a yellow “electrical system malfunction” alert. Shortly after an alert that said my start-stop function was no longer available. After about 20 minutes I received a red electrical system malfunction: stop vehicle safely. Thankfully I was pulling onto my street when the last alert popped up.

The car displayed a warning that the electrical system had a fault and to contact service. I then contacted service and they said to drive it to the dealer as it sounded like a known issue with the generator/starter and 48v system. On the way to the dealership, the warnings continued and then various systems began shutting down, including the steering and the transmission. I was going at a relatively slow speed on a side street at the time, which was fortunate, as the car locked up all four wheels and had no steering and the engine quit. Thankfully it was a side street. If this was a major street or highway, it quite likely could have caused a serious accident or injury. In contacting Audi USA, they do not have parts available to fix this issue, and the dealership confirmed that they are unable to fix the car at this time.

Starter generator/alternator problem. I was driving and suddenly got electrical malfunction issue and slowly all electronics in the car stopped working. Got the car towed to Audi service center and the service representative told me it was starter generator issue and it’s widespread. Dropped the car on 11/15/22 and still waiting for my car to be repaired.

The contact owns a 2019 Audi A6. The contact stated that while operating the vehicle, the warning message "electrical malfunction" suddenly displayed along with a red battery icon. After turning off and restarting the vehicle, the message remained displayed, but the battery icon changed to yellow. The vehicle was taken to the local dealer who diagnosed that the starter generator was faulty and needed to be replaced; however, the part was on backorder and would not be available for several months. The manufacturer was not yet contacted. The failure mileage was 42,000.

I get a message on the dashboard while driving that the electrical system failed. There is a message later that says the "start/stop system: malfunction! function unavailable. Please contact service".

The starter/generator (formerly known as alternator) of our A6 3. 0 needs to be replaced, the part is back-ordered for approximately 60 to 90 days. The yellow indicator light goes on and then the car shuts off. It happens without warning and is incredibly dangerous.

Battery light came on, called the dealer and they said don't drive and towed the car to dealer. They said need to replace starter generator c29. They did't have parts, so they keep my car at Audi dealer service shop for about one and hale month. I googled and look like it happened to too many people. Finally they said found the parts and charge me $2902. 12. I am really concerned that part is not properly constructed or something, as even in this dealership, they said my car was sixth in one month and may more after me. They are skimming money from bad part.

While driving my 2019 Audi A6 premium plus I received error messages: "electrical system malfunction contact service", then "start stop system malfunction contact service", then "electrical system malfunction stop vehicle safely". I went on an Audi owner internet forum and read about others with the same errors. Reports from others indicated that in about 40 miles from the first message appearing, all systems will completely shut down including the engine while you are driving. This could leave you stranded in the roadway if you are not able to pull over in time and requires a tow; the vehicle cannot be relied upon to get you to a service center at that point. My vehicle was in a parking lot at the time for a few hours. I was able to start the vehicle. It presented the first two messages immediately. I was able to drive another 10 minutes to arrive at home safely. On my way home the check engine light came on and as I got to my driveway "electrical system malfunction stop vehicle safely" appeared again. Two days have passed (where I did not operating the vehicle anymore) and I've now had the vehicle towed to my Audi dealer / service center. My service advisor called me back this afternoon saying that they confirmed starter / generator / alternator needs to be replaced. The alternator (only) is now on order for me with no eta. He said the last one they fixed with this issue took 42 days. He said he has 6 vehicles on the lot with the same issue. This issue appears to be popping up for all early builds that has the Audi 48v mhev (mild hybrid battery system). Other owners report they needed their 48v and sometimes 12v batteries replaced. As I mentioned earlier they only ordered the alternator at this point; I'm worried that my batteries cannot be trusted after this issue as apparently the cells in the 48v become unstable after entering this state.

Electrical system malfunction caused by a faulty generator which was confirmed by Audi connection (servicing dealership) in cincinnati, ohio.

Mid December the day after I purchased my 2019 A6 the 48v starter generator failed while driving with my son in the car. Alerts came up as electronics issue and to pull over. Very quickly it stopped dead in road. They told me it is a known issue, and they have multiple A6s waiting for this part. It has been over a month and still unknown when this part will be available. This should be a recalled item, but is under warranty.

Starter/generator failure. Message: "electrical system malfunction" car became disabled intermittently. Brought to dealer despite no service appointment available for more than a week. Dealer advised me that 7 other A6 models were in with same issue.

Warning appeared for electrical malfunction contact dealer. Within 15 minutes of driving to the dealer, electrical failure please pull over appeared. My antilock breaks, transmission, and finally the entire electric panel failed. The car entirely stopped while in traffic. I was unable to even turn on hazard lights. It would not turn back on. It required towing to Audi dealership. I have been told by Audi the starter generator died.

The contact owns a 2019 Audi A6. The contact received notification of NHTSA campaign number: 22v155000 (electrical system) however, the part to do the recall repair was not yet available. The contact stated that the fuel gauge was not working as designed. The vehicle was taken to the dealer where it was diagnosed but no cause for the failure was found. The vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the failure. The failure mileage was approximately 13,514. VIN tool confirms parts not available.

On December 16, 2022, the alternator on the vehicle failed, which prevented the battery from charging. Luckily, I had just parked the car when all the electronics shut off - otherwise I would have been driving on a busy street with the potential for an accident. The vehicle was towed that day to white allen european auto group in dayton and is still there and available for inspection. Today is Feb. 6, 2023, and they are still unable to get the required alternator parts and we don't have an eta. To my knowledge the vehicle has only been assessed by their technician, not anyone else. There were electrical issues prior to the failure. I took the vehicle to white allen on Nov. 22 due to warning lights for lane departure warning and lane keeping assist turning on and off, as well as issues with the engine shutting off at traffic lights and being unable to get the car to move without turning it completely off and back on again. When I took it to the dealership, they performed many vehicle recalls and repairs including multiple software updates, reworking the transmission wiring harness, servicing the start/stop system, airbag inspection, battery load, control module update, mmi software update, etc. I picked up the vehicle on November 30, 2022. On December 5, 2022, I had to take it back to white allen because the bottom display screen was not functioning properly. (when starting the car, the top half of that screen was scrambled and the bottom half was dark. After driving for a while, the screen would begin functioning properly). They diagnosed it as a hardware issue with the top screen that controls the lower screen. I was told they would replace the top screen, and the parts should be available by December 29. I asked if the car is safe to drive, and they said I could continue driving it as the lower screen doesn't control anything that might be a safety issue. On December 16, the car stopped working and I had it towed back to the dealership.

Vehicle emitted multiple warnings via dashboard displays. Called dealer's service department and they advised to bring vehicle to dealership as soon as possible. They suspected the car was experiencing pending failure of the generator or alternator, which could result in an immediate loss of all electronics, posing a serious risk while driving. I attempted to drive car the 10-15 miles to the dealership the next morning and all systems failed. Dealer confirmed issue was related to the suspected generator or alternator issue.

Starter/generator alternator failed and caused the battery to die ultimately leading to losing full power of the car on highway. Warning lamps were present and indicated "electrical system malfunction and contact the dealer for service. " car lost full power on the way to dealership and almost resulted in a crash. Component has been inspected by the Audi dealer and confirmed to be the issue. Symptoms appeared very quickly and within 30 minutes of the symptoms the car was inoperable.

A warning message appeared that there is an electrical system problem. I arranged to bring to dealer for service the next day. While driving to dealer, multiple malfunction messages appeared on dashboard. Eventually all displays went black and shortly thereafter the engine stopped. I rolled to a stop. Car was dead. Audi stated it needs a replacement starter/generator. Very dangerous as it happened to me on an interstate. My research shows that this is a not uncommon problem.

While driving on an interstate highway, an electrical fault warning appeared. 5 minutes later, a series of warnings appeared pertaining to a whole host of Audi systems, and I suddenly lost power to the car. I coasted off the highway to the shoulder, where the car died. I was told by the dealership that the issue is a generator, and that it's a common issue affecting A6s. It was truly disconcerting to lose power, without much warning, when driving.

While out of town the car gave an electrical system fault with a yellow warning saying find a dealr soon. Then shortly after the warning went red and while driving all systems in the car started to shut down. Steering, transmission, throttle, dash, everything went crazy. Need to to cross 2 lanes of traffic to get off main road where there was no shoulder to pull onto a side road, very scary without power steering and the transmission putting itself into neutral. Easily could have caused an accident with my wife and 2 kids in yhe car. At that point the car was dead.

The electrical system malfunctioned driving on the busy 422 expressway. Going at 55mph. Car dash lights up warning signs like electrical system failure, transmission, brake, power steering failure and the car shuts down in the middle of the road. Steered it to the side of road. Car would not start. Had to get it towed to dealer, car has 33000 miles. The dealer has confirmed the failure. The component has been inspected by the dealer. Could have had a serious life threatening accident posing death or injuries to self and others.

-total electrical system failure (dealer confirmed starter generator). -after a short time of cautions followed by warnings, engine and all electrical components quit working. (no hazard lights). No way to warn other drivers on the road or highway to a malfunctioning vehicle -dealer confirmed starter generator needs replacement. Waiting on part (60+ days and counting) -caution and warnings started appearing about 15 miles before the car became completely underivable. (every electrical system caution began appearing followed by warnings of impending engine shutdown).

On thanksgiving day I received a warning on my display: "electrical system: malfunction! please contact service. " the next day I contacted ellis Audi in atlanta and was able to drive about 3 miles to take the car to them. At the end of the day they said I needed a new alternator/generator and the car should not be driven. They said the part was on backorder and they already had about 11 cars needing the same part. Since then they received 7 parts but now have about 20 cars on their lot requiring repair.

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. Flatbed towed to dealer who stated most likely the generator between the lithium battery bank and gas engine failed. They have seen several in this year for A6 and a7's with mild hybrid engines. I'm lucky to be in low volume traffic as there was no power to indicate to drivers around me that my engine quit and not even turn signals worked.

I was driving across the george washington bridge towards NJ and I received warning of electrical issue, then transmission warning and the car promptly shut down, leaving my wife me stranded in the right hand lane with no shoulder. Had to call 911 to get assistance. Once at the Audi dealership I was told it is an issue with the alternator/electrical system and the car is undriveable until repaired. Unfortuately the part is back ordered and the car has been at the dealer for over three weeks. According to the service team and driver forums this is a major issue with 2019 A6, a7 and they are failing at an alarming rate. Not sure when I will receive the car back and they are not providing any loaners or rentals. This repair will cost 4,000, luckily mine is under warranty.

I experienced a total failure of the electric system in my 2019 A6. Car stopped running in the middle of the road. Had to use the tool in the trunk to manually switch the car to neutral so I could push it off the road. Car was towed to the Audi dealer in my area. Audi dealer reported the alternator is faulty. Yellow electrical issue warning message showed up on, dashboard, then red electrical issue message showed indicating the vehicle will shut down. Dealer reported “a bunch” of A6s 2019 and newer are expediting these issues and parts are on back order because of it.

On November 8, 2022, I was driving my vehicle to the Audi arlington dealership to service an "electrical system malfunction" alert that had recently appeared. Approximately one mile into my drive the car completely shut down while driving. This happened while I was proceeding through an urban intersection. All systems shut down on the car simultaneously, including every screen, hazard lights, engine and power steering, to name a few. I was able to coast to a stop while only partially exit the lane of traffic. As the car was entirely nonresponsive, it needed to be towed from that point to Audi arlington. Audi arlington determined that the issue resulted from a 48v generator.

My wife was travelling on the interstate at about 75 mph, when all of the dash lights flashed in red that there was an electrical system failure. At this time, while driving in the fast lane, it seemed like all systems including steering and power brakes failed. She managed to make it across four lanes of traffic before the car died completely. Once we got the car towed to the dealership, they informed us that it was a failure with the 48v generator and that it would be at least 2 months to fix the problem because the part was on back order. It has now been 2 and a half months, so I called the dealership and they told me they have 31 of these to change and my car is still a few weeks away from be repaired.

Component failed: believed to be starter generator part number 4n0-903-028-p on 11/04/2022 cause: ended up stranded on the side of the highway at night with no power, to include power steering and hazard flashers. Car had to be pushed out of the high way to avoid being hit by traffic. Problem is ongoing and easily reproducible. Manufacturer confirmed faulty starter generator on 12/15/2022 from first indicator lamp of electrical issue to full shut down of car was about 20 minutes.

Received an electrical system malfunction on display. Took to dealer for diagnostics. Was told the starter/generator needed to be replaced and was going to cost $4000 but parts were on back order with no eta. It’s been 3 weeks with still no part and no loaner car available. This is ridiculous. This is a new car.

The electrical system failed while driving at highway speeds on the interstate. Car lost power, all safety systems shutdown and I had to navigate the car while coasting off the road. Car would no longer start and left me stranded on the side of the interstate for 2hrs. I have since learned from the Audi service department that the 48v generator had failed and caused this situation.

Today, car showed electrical problem then leading to steering problem, transmission problem, all sensors shutting off, all thro flashing one by one alarms and messages on dash and then coming to a complete halt. It would not allow me to come out and locked me in. I could see that the locks were kicking in so took a micro second gap between unlock and auto lock to get out of the car forcefully. I have had situations when in traffic light, the car wouldn’t move back from neutral to drive unless I tried couple of times, but this was horrible incident. Now taking it to service to see what they are going to say, not always super helpful.
