Failure Date: 01/06/2025

Yellow battery indicator light came on while driving car in 35 degree weather after a week of sitting in garage (holidays). I pulled over, read the manual and it said this could cause battery light to illuminate. I called the dealership service to ask them, they said possible reason. I decided to drive across city to dealership, 25 minutes away. On hov lane, red warning lights flashing to pull over then 5 seconds later everything went black. No electrical, no engine, car died. Very dangerous!! read later that this has been happening on Audi A6 (& other models) for 2+ years. Towed to dealership and they have had 1. 5 weeks and still not fixed.

Audi is aware of the starter-alternator issue which is documented in Audi's emissions service action code: 27bq dated 4/30/24. Audi didn't communicate this to the effective users until October 2024. I personally experienced the defect in my starter-alternator on 10/21/24 and proceeded to have my car repaired.

10 Electrical System problem

Failure Date: 12/22/2023

A yellow warning light went on stating"electrical system malfunction" start/stop is not working. Within 5 miles a red warning light went on that stated pull over when safe then within 100 yds multiple warnings went off and I lost power steering, power brakes etc. I was able to get stopped but the car would not start nor was I able to even put it in neutral to have it towed. I researched the issue and it seems to be a well known issue with the alternator. There has been several state lawsuits in regards to the issue. But no recalls or information sent to owners.

11 Electrical System problem

Failure Date: 12/21/2023

The car gave me a written error message on the dashboard that there was an electrical system malfunction. I thought to myself, "gotta get that checked out. Let's see if it goes away. " I drove a short distance home and parked. The next day I began to drive to work. I got the electrical system malfunction message again. I decided to pull into a parking lot and make an appointment to get it fixed by the dealer. Then, I began to drive back home (didn't want to risk driving to work). The car then gave me a new message that the electrical system was not working and to pull over safely. I drove for 30 or so more seconds as all the systems began to shut down. The car completely stopped within a minute or 2 of the error message, stranding me in the middle of the road. It was impossible to shift it into neutral to safely move it. If I had been driving on the highway, it would have been really bad! there was almost no time to get the car to a safe spot and no chance to put it into neutral to move it. The car has since been diagnosed with a faulty generator that needs to be replaced.

12 Electrical System problem

Failure Date: 12/04/2023

Electrical fault dash warnings (steering, transmission, braking and many other things too numerous to mention came on while driving the car and it went into limp mode and forced the car to stop and would not restart. The car had to be towed to the dealership where they diagnosed the problem to be the "alternator" which is more accurately what is known as the "belt starter generator" bsg. The bsg runs the start stop feature of the car and charges the mild hybrid 48v battery system that runs many of the critical features of the vehicle. They do not have the part in stock and do not know how long it will take to get in. I understand that there is not an upgraded part available that will fix this issue, only the same part that they are continuing to put on all of the v6 engine models since 2019 to today. The A6,7 and a8 and q5,7 and q8 models in particular are being affected. This is an extremely dangerous problem that has not been remedied by Audi/vw to this point and the NHTSA should issue a recall.

13 Electrical System problem

Failure Date: 10/25/2023

Vehicle stopped and is not operational. Dealer stated that the generator went out. Part is not available due to this problem occuring on so many vehicles. Vehicle has been in the shop since late, October it is now November 28th and still no eta on part arrival or repair completion.

14 Electrical System problem

Failure Date: 10/25/2023

First sign of the vehicle is shaking and making noise while driving over 65mph. A few days later, the tire pressure warning was on. The next day, electric system malfunction light was on, advising me to contact service center. At the same day, steering function light was on and it was stiff to drive the vehicle. A few miles down the road, engine shuts off, and was unable to restart.

15 Electrical System problem

Failure Date: 10/21/2023

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!".

16 Electrical System problem

18 Electrical System problem

Failure Date: 09/21/2023

Received a message for "electrical system failure" and drove ok at first but began receiving failure messages for various systems including but not limited to start/stop system, transmission, power steering, and crash avoidance systems. Soon after the entertainment and comfort system screens went blank followed by the dash screen and the car eventually just turned off as I was trying to find a safe place to pull over. Safety was put a risk as I was stranded on a busy road with no shoulder and because the battery was impacted my hazard lights only lasted a short time which left me and my vehicle exposed on the side of the road. The car was towed to the dealer (Audi of albany) who inspected determined the failure was related to a faulty ignition generator. The car is currently at Audi of albany and will be for at least 2 weeks so I am assuming it would be available for inspection. Many different warning lights appeared in the short time leading to total shutdown of the car. I recall a start/stop failure message, batter charge low, transmission failure light, power steering failure warning, adaptive cruise control, frontal collision avoidance among others. As stated above all screens in the car eventually turned off and the car fully failed on a main road and required a tow to the dealer.

19 Electrical System problem

Failure Date: 09/08/2023

This is my second entry/complaint regarding the same extremely dangerous steering malfunction. While driving my 2019 A6 (this time alone) in heavy rain the same warning message was displayed. The warning stated: steering malfunction, please stop the vehicle!. At which point the power steering locked-up & the engine powered down. As a result, I was unable to steer the vehicle. One again I was able to exit the highway safely. Being close to home with only a few turns, I was able to “limp” the car home, parked in my driveway and contacted Audi. Currently it’s at nyack Audi awaiting service on Monday 9/11. This is a huge safety issue and needs to be addressed. Doing a bit of online research & reading countless Audi blogs, I found out this to be a common issue with other Audis while driving in the rain. Fist time this occurred was 6/16/22, driving a 2016 s6. Tracking # for that entry is 11543563.

20 Electrical System problem

Failure Date: 09/05/2023

On my way to work, my car alerted me to an electrical malfunction and told me to call for service. When I called my Audi dealership, they told me to bring it in for service the following week. After asking if the car was safe to drive, they told me they wouldn't know unless they looked at the car. After pleading with them, they agreed to an appointment that day. On my way to the dealership - about 10 minutes into the trip on a highway, driving at highway speed, all electrical systems in the car started shutting down, and quickly - air conditioning, all safety features like lane keep assist, collision avoidance, etc. The steering became very heavy, the brakes were underperforming. After slowing down safely, the car shut down and was completely immobile and inoperable.

21 Electrical System problem

Failure Date: 08/29/2023

Car started by saying auto start /stop function malfunction, than electrical malfunction. After reading an Audi forum on Audi world there is thousand of customers complaining of the same issue. Apparently its a known issue with their 48v mild hybrid system and their alternator. Multiple dealerships blaming a faulty alternator. This issue has left people stranded and myself the vehicle a/c system stopped working and now parked at home until I can take to dealership. This issue is not a small one or impacting a small amount of consumers and more investigating should be done by your agency to be a recall on this. Thx.

23 Electrical System problem

Failure Date: 05/30/2023

Was driving and car gave me an electrical system malfunction, shortly after all lights (abs, esc, power steering, brakes) came on and vehicle died right after. I was traveling at 25-30mph and was unable to control my vehicle. I had to have the vehicle towed to a shop because it would not start after. After some research, it seems to be a problem with the 48v mild hybrid system. Thousands of known cases this should be a recall! extremely unsafe.

24 Electrical System problem

Starter warning followed by electrical system malfunction, these were followed by multiple warning lights (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.

25 Electrical System problem

26 Electrical System problem

Failure Date: 04/24/2023

Massive safety liability here. My 2019 Audi A6 was on the highway traveling at 75mph on 4/25/2023 at noon when with no prior warning, all of the electrical systems started failing rapidly. In the course of 90 seconds, there was an electrical malfunction warning, quickly followed by malfunction warnings for steering, brakes, and cascading shutdowns of all systems like the transmission, abs, collision warning, lane departure, lights, hazard warning lights, instrument screens/clusters, hvac, windows- literally everything. A complete failure of every component and safety system while driving highspeed is extremely dangerous. Had this happened at night, I would have been bricked in the middle of the road without headlights, hazard lights, airbags, etc. The car had to be towed away to the dealership and is available for inspection. The dealer is aware of this issue and called it a 48 volt starter/ alternator issue which is apparently systemic/ widespread with 2019-21 Audi 48 volt architectures; parts are generally backordered for months. Please take note: there is an extremely high risk that someone will be killed and seriously injured as a result of this defect. The vehicle is awaiting inspection and repair at an Audi dealership. It is under extended manufacturers warranty at 50,700 miles. No other diagnostics/ inspections/ or reports have taken place yet.

Message for "electrical system malfunction", then "start stop system malfunction", then "electrical system malfunction stop vehicle safely". Car was immobilized. Was driving on highway.

28 Electrical System problem

Failure Date: 02/22/2023

Two miles from home all sorts of electrical malfunction warning ?? lights appear. Too many to list here. Then car completely stops and all electricals shut down. This happened in the middle of a very busy three lane 45mph main artery. Stuck in gear, unable to push off side of road. After ten minutes or so of cars zooming around us, it started enough to get off road to safe place. Waited 4 hours in freezing cold for tow truck. Very scary incident for my wife and me, as we are in our 70s. Towed to my local Audi dealer. The problem seems to be with the “starter alternator” and is a national problem with 1000s of affected owners. Was told 29 vehicles are ahead of mine for replacement and that it could be weeks before parts are available. One car family and no loaners available and there talking weeks / months to repair.

29 Electrical System problem

Failure Date: 02/11/2023

I had a failure with the vehicle electrical system malfunction. I had multiple warnings from abs, power steering, adaptive cruise control. I was on the highway doing about 70 when this happened. After about 5 mins of driving, everything powered down in the vehicle. From the dashboard to the center instrument panel. Then after that, the car cut off. Lucky I was in the right lane to pull over to the shoulder. Car never started back up. Nervous about what the dealership is going to tell me.

30 Electrical System problem

Failure Date: 02/05/2023

Electrical system malfunction w/yellow battery icon. . . Stop/start system unavailable. Vehicle deemed unsafe to drive. Towed to dealership, part on worldwide b/o. . . Estimate several month wait for starter/alternator.

31 Electrical System problem

Failure Date: 02/05/2023

I suffered a complete failure of the vehicle's electrical system. First, I received a warning that the electrical system malfunctioned. This warning went away after two power cycles. Two days later the warning came back and a warning that the battery level was low. I was driving the vehicle approximately 1 mile on the highway when the warning became progressively dire. First the adaptive cruise control systems became failing one by one, adaptive lane keep, lane departure etc. Then I got yellow warnings about failures in the transmission and the engine. Finally those errors became dire that I must stop the vehicle. I next lost all electrical screens within 2-3 minutes of the cascading dire warnings just as I was pulling off the highway onto side streets. Within 30 seconds I lost power steering and most braking force. I was able to pull over into a bus stop, but with difficulty. I lost all hazard lights, all vehicle lights. I lost the ability to unlock the doors temporarily but this recovered. I could not turn the car back on, I could just hear the started struggling to turn over. None of the screens in the vehicle worked. No lights or horn worked. Thankfully this happened in the late afternoon while the sun was still out. The extreme danger posed by not having emergency lights, power steering and minimal braking capability made this an extremely scary situation. I was advised by Audi queens that this was confirmed alternator/generator failure.

32 Electrical System problem

Failure Date: 02/03/2023

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 unavailable. The local dealer was contacted, and it was confirmed that the part was not yet available. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced the failure. VIN tool confirms parts not available.

33 Electrical System problem

Failure Date: 01/30/2023

It appears that the 48v hybrid alternator failed. The vehicle completely shut down/lost all power while driving 50 mph on busy road. Almost rear ended while trying to coast to a stop. Low battery light came on the day before. The day it failed I was driving it to the dealership.

34 Electrical System problem

Failure Date: 01/28/2023

Vehicle's on board system reads "electrical malfunction: start/stop system malfunction. Call service". Then this triggers a complete shutdown of the vehicle: transmission, steering, distance, and braking sensors, etc all got affected.

35 Electrical System problem

Failure Date: 01/26/2023

While I was driving, the vehicle gave an electrical system malfunction warning. When I stopped and restarted the vehicle, the car reluctantly started with delays and a check engine light. I had to tow the car to the dealership. Upon inspection, they determined it is a generator issue, much like many other owners of 2019+ model year of Audi's. They do not have an eta on the replacement part, and thus the car will be out of commission for weeks to months. I am lucky, as many other people who have experienced this problem have had their car completely die on them in the middle of driving. This is a potentially dangerous safety hazard, and an enormous inconvenience, as any Audi owner with this generator issue will not have their car for weeks to months.
