Red start/stop malfunction light, then Electical System yellow light malfunction, then Red light Electical System safely stop vehicle all with 2-3 min while driving in normal city conditions

- Beaverton, OR, USA

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.

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

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.

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

1 / 2 ? Purchased 2019 Audi A6 Prestige sedan in August 19, 2023 Issue #1: Transmission Issue ? Day after purchase, transmission error appeared on dashboard during highway driving ? Car acted up a little, so quickly got off highway and drove home. Emotionally scared ? Called tow company to haul to dealership the next day ? In the shop for few days and didn-??t have a replacement vehicle. ? Also got some message about air bags ? I have email communication about these issues with Audi Issue #2: Three safety recalls and periodic electrical warnings between 2019-2022 including... ? Inaccurate fuel level indicator o 6-7 months between recall notice and fix o Consistently thinking about range #3: Issue Alternator ? 6/22: Warning message appeared on dashboard indicating battery issue, take for service ? Friday, 6/23: Took to an widely recognized car shop (specializing in imported vehicles) close by to check it. Mechanic summarized that the alternator voltage output is low. Battery test good. ? Recommendation was to replace alternator. Car shop couldn-??t get replacement due to supply backlog. o 1:00 PM: On the drive back on highway, frequent warning messages appeared on dash and the car suddenly started accelerated/decelerating. Immediately pulled onto the breakdown lane. o 2:30 PM: After 1.5 hours, Tow truck came to pickup vehicle and take it home o 2:30 -?" 4: Struggled to get car started to pull off trailer.

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.

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.

While driving the vehicle states that there was an electrical fault and to contact a service center. This was associated with a loss of drive power that made handling more difficult. A dealer advised me this morning that this is a common issue.

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.

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.

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.

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.

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.

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.

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.

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
