Electrical System Problems of Audi A6 - part 1

While driving slowly through a shopping mall parking lot with my wife and [xxx] son onboard, the vehicle suddenly malfunctioned. The central locking system cycled repeatedly, and a warning briefly appeared mentioning a steering/light malfunction. Immediately afterward, the emergency release cables for all four doors deployed externally as if the car had been in a crash, even though no collision occurred. At the Audi dealership (Audi sugar land, TX), technicians confirmed by diagnostic scan that: the abs control module stored a fault for “invalid data. ” that invalid data was relayed to the airbag module, which falsely triggered a “crash response active” condition. All four door modules stored crash response faults and deployed the emergency release cables. The issue was confirmed, faults were cleared, but no parts were replaced. This false crash response put my family at risk because it activated emergency safety mechanisms without cause. My concern is that if invalid data can trigger a false crash event, it could also trigger other systems, such as airbags, leading to potential injury. The incident occurred with approximately 1,100 miles on the vehicle, one week after purchase, and immediately following the first 100% charge. The dealer documented the event and consulted Audi technical assistance, who authorized release of the vehicle after clearing the codes. This is a serious safety defect because critical systems activated without a real crash, creating unnecessary risk for occupants. The vehicle is available for inspection upon request.

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.

Vehicle had electrical system malfunction. Vehicle provided an electrical system malfunction and vehicle starting system malfunction warning message a few days prior to the incident. Vehicle has approximately 20. 5k miles on odometer. Before I was able to bring it to service, the electrical system malfunction message became more severe and turned from yellow to red. While driving, the vehicle progressively shut down abs, lane departure, and other systems and gave a transmission warning message. Eventually, the car lost power and I was left stranded at the side of the road.

The contact owns a 2016 Audi A6. The contact stated that while driving approximately 40 mph, the vehicle suddenly experienced a loss of motive power and stalled. During the failure the message electric power control "epc" was displayed. The vehicle was later towed the local dealer who diagnosed that the electric wiring harness located in the engine compartment had failed due to moisture intrusion and the harness along with an internal computer needed to be replaced. No further information was available. The vehicle was not yet repaired. The failure mileage was 49,000.

I took the vehicle into a repair shop because the check engine light is on. I was advised that the water pump is leaking and it needs to be replaced along with the thermostat. The turbo charger assembly also needs to be replaced. Both of these items appear to be deficient and were listed under recent recalls on similar Audi vehicles and this VIN was not included in either recall. However, it appears to be a similar concern and should be resolved by the manufacturer.

Electrical malfunction warning. Steering wheel got tight. Transmission failure warning. Then the the car began to stop. All types of various warnings were popping up on the heads up display. It is in the process of getting taken to the nearest dealer.

When backing up the car the cameras don't turn on and often times the collision sensors go off randomly. On the highway the emergency brakes go off randomly when a car passes by on the right-hand side of the vehicle.

Car flashed several warning signs, electrical system malfunction, steering malfunction, lane assist malfunction, and finally powertrain system malfunction where car was barely driveable at very slow speed, died and I luckily was able to pull over and coast into a parking spot.

Car slowed down and shut off in the middle of the road.

The car gave me electrical malfunction warning while driving on the highway, then all the screensturned black, and the car completely shut down while driving. The steering was still working, although heavier than usual, and the breaking also worked. The car slow down to a complete stop at the shoulder of the highway. This was very concerning, and thankfully happened close on exit with a shoulder at the side in which I was able to park the car.

Warning light came on for electrical malfunction and many other malfunction lights car then shut down.

The car couldn't start and stopped abruptly on the way through bunches of errors on the dashboard with check engine light and steering was firm and could not lock the car or open the door here are the warning list for 2019 Audi electrical system malfunction electrical system malfunction parking aid malfunction transmission malfunction rear spoiler malfunction drive system: malfunction traction control malfunction tire pressure monitoring system malfunction parking brake malfunction automatic start/stop system malfunction start/stop system malfunction.

The car has had multiple issues with warning lights and malfunctioning systems. Including : 1. Child locks 2. Every single component of the adas 3. Emergency services being activated at least a few times a month - this is an sos for emergency 911 service. The repeated, continuous and mostly false warning lights are a driving distraction that can easily cause an accident. I have photos of all warning lights coming on in the vehicle. The dealership has repeated stated that they couldn't reproduce the problem even though pictures were provided and the car is still under the original warranty period. The latest attempt to fix the vehicle was to replace the sensors on the front of the vehicle. This solution was only attempted after the 4th report of the problem to the dealership where the car was serviced under the original manufacturers warranty.

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.

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.

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.

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.

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.

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!".

Car shut down while driving due to the electrical system malfunction; had to get the car towed; ended up being a known issue by Audi with no recall related to the alternator; replaced with new alternator.

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.

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.

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.

Car reported an engine restarter issue (with battery symbol) and recommended to contact the dealer. Car next shut down automatic restart system, and air conditioning stopped working. Within a short period of time (same day), the car listed a red battery symbol and advised to stop the car. After doing so and contacting the Audi roadside, the car was listing a series of issues on multiple symptoms while also saying in the warning message "still okay to drive". These systems included steering, braking, and what seemed to be other sensors the car powers. Finally (and within 5 minutes of the previous message of being okay to drive), the warnings were continuous and started including the transmission. The car stopped accelerating (we were on the expressway) and we thankfully got to the side of the road. This was an enormously dangerous situation as the car became fully disabled and we were subject to limited options of relief from a major traffic area. Within 30 minutes of being disabled, no electrical charge was present in the car, including emergency flashers, making the situation more dangerous as it was nighttime, so we had to abandon the car and walk down the expressway to find a hotel. Could not even put the car in neutral for the tow. Service is initially reporting a failure of the restart generator. This appears to be an alarmingly common issue with Audis.

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.

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.

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.
