NHTSA Owner Complaint Log
This page lists owner-reported complaints filed with NHTSA for the 2021 Audi Q7. Complaints are unverified consumer reports submitted to NHTSA and do not by themselves prove a defect or defect rate.
I am submitting this complaint regarding a safety-related recall on my Audi Q7 involving the alternator. The wording of the recall is significantly underplayed, written off as an emissions issues. When in reality this is a life threatening flaw in the alternator. It is highly concerning that Audi isn’t being transparent with people who are driving these cars and risking their lives while doing so. This is not simply emissions, in reality, the car can totally malfunction while in operation. The entire electrical system fails and the car completely stops responding to the driver, fully stops and dies no matter where you are driving or at what speed. While driving on the highway, my vehicle experienced a catastrophic electrical failure caused by the recalled alternator, which caused the car to completely stop and it would not restart in any way. This created a life-threatening situation for my family and me. As a result of this electrical failure, the vehicle’s battery was damaged, and Audi has acknowledged coverage of 90% for the battery repair. However, the voltage converter, which is part of the same charging system, was also damaged during the same event. Audi is refusing coverage for the $1,600 repair of the voltage converter, despite the damage being caused directly by the alternator failure. I believe this represents a significant safety risk, as the vehicle’s sudden loss of power could lead to serious injury or death. Additionally, the recall itself caused secondary damage that is being denied coverage, which is unfair and unsafe. I am requesting that NHTSA review this matter as a safety defect/recall-related failure, and ensure the manufacturer addresses all consequences of this recall-related defect, including coverage of secondary damage like the voltage converter.
I was driving on the freeway and got off on an exit ramp at high speeds and began to slow down and break. As I was breaking the car became clunky and slowed down and suddenly shut off. The warning lights “transmission failure and “ESC failure” came on and I was unable to drive or put the car into gear. The car flashed “stop. Pull over” and “not safe to drive” and see “Audi dealer”. The car would not turn back on. We were stuck in the middle Of the freeway off-ramp with cars flying by us with no sidewalks or safe ways to exit the vehicle. I had my wife, dog and 2 and 4 year old kids with me. I then had to be towed to my local Audi dealer. At the Audi dealer, I told them what happened and asked for a full diagnostic. They then called me the next day and said they ran codes and nothing popped up. I said can they run a full diagnostic further and see what happened. They called me the next day and said they did a “deeper dive” and I needed to replace my transmission intake body valve and gave me a repaid quote of $8,000. My car had been serviced 2 months prior on 10/16/25 with the transmission being checked and said great.
The vehicle was parked on a sloped driveway. After the driver exited the car, the automatic parking brake/Auto-P fail-safe failed to engage. The vehicle rolled backward unexpectedly, causing the driver-side door to strike a fire hydrant and rebound into the driver's body. There is significant property damage ($6000) and personal injury. Complete home security video footage of the incident is available [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
The contact owns a 2021 Audi Q7. The contact stated that the rear-view mirrors on the driver's side failed to indicate when another vehicle, person, or object was nearby the vehicle. The passenger's side rear-view mirror's audible alarm occasionally erroneously alerted the driver that there was a vehicle, a person, or an object nearby the vehicle. The infotainment screen occasionally blacked out, and the following day, the screen activated but failed to finish uploading all the systems and functions. The back-over prevention camera alarm made abnormal sounds compared to the normal sound. The infotainment center intermittently failed to display the icon indicating that the key was in the ignition after the vehicle had been started. The vehicle was not taken to the dealer to be diagnosed or repaired. The contact was unaware that the vehicle was included in NHTSA Campaign Number: 25V900000 (Back Over Prevention). The manufacturer was not informed of the failure. The failure mileage was approximately 44,000.
- Engine water pump failure and coolant intrusion into the vacuum system. Parts were replaced on 5 Nov 2025 and possible still at the dealer's location. - The defect poses the following safety risks: It resulted in contamination of vacuum lines; potential for sudden engine stalling or loss of power while driving; potential for catastrophic damage to engine-management systems dependent on vacuum integrity; potential for damage to emissions and combustion-control systems; potential for reduced braking system performance if vacuum supply is compromised, expensive and unexpected component failures, and possible recurrence since the cause appears related to design rather than normal wear. Any failure can create cascading hazards affecting safety-critical functions. - The problem was confirmed by an authorized Audi dealer. Dealer name and contact info can be provided upon request. - I do not know if the dealer delivered the involved parts to the manufacturer or insurance representative for inspection. Police or others did not inspect it. - There were no warning lights, messages, or other symptoms of the problem prior to the failure. It was identified by the Audi technician on 5 November 2025 while the vehicle was in the dealer for other services. The failure occurred at 47,855 miles which is far below the average lifespan of a water pump or vacuum system.
I am filing this complaint regarding a serious safety and mechanical issue involving my 2021 Audi Q7. The alternator on my vehicle was replaced by Audi in November 2024 as part of an official Audi recall. On October 22, 2025, less than one year later, the alternator failed while I was driving, causing the following safety hazards and damages: Sudden loss of battery power Complete battery drain Damage to the electrical stabilizer Vehicle shut down while driving Required towing Left me stranded on the road Another independent auto shop confirmed that the alternator failure directly caused the battery to fail. My vehicle is only four years old, and the battery should not fail under normal operation unless another component (such as the alternator) is defective. Audi of America refuses to cover the resulting damages, even though the alternator was replaced under their recall and failed prematurely. They have denied reimbursement for repairs, towing, and related expenses, despite clear evidence that the alternator caused the battery and electrical damage. This is a serious safety concern because the alternator failed without warning, and the vehicle lost electrical power while driving. I am requesting NHTSA to review this issue, as the failure of the recall-installed alternator may impact other Audi Q7 owners and may indicate a broader defect or improper recall repair. Thank you for your attention to this matter
An alert popped up on the dashboard. Stating driver system malfunction. This happened on the freeway and then the car shut down immediately. I've gotten this notification over 8 times and it has yet to be fixed. I'm extremely anxious and terrified when driving this vehicle, because my 3 children are in this vehicle while im driving. All services has been all done at audi oakland, they have all the records/documents. This car has been serviced over 120 days in total
During a routine service on my 2021 Audi Q7, the shop found the coolant level low and traced it to a leak. The Audi dealer later diagnosed failure of the water pump, thermostat, valves, and related parts, with a repair estimate of nearly $5,000. I discovered that prior model years (up to 2020) were included in a class action lawsuit for the same type of cooling system failures, though my VIN is not covered. This appears to be the same issue, happening just a few months outside of warranty, and raises concerns about premature failure and safety risk from overheating.
The contact owns a 2021 Audi Q7. The contact received notification of NHTSA Campaign Number: 25V201000 (Electrical System). The interface turned off, and the touchscreen was inoperable. The CP message was displayed on the instrument cluster. The vehicle was taken to the local dealer, who confirmed that the USB port was not working and was not covered under warranty. The vehicle was not repaired. The contact reached out to another local dealer, Audi Riverside (3210 Adams St, Riverside, CA 92504), but no additional assistance was provided. The manufacturer was contacted and offered a discount on the repair, but no additional assistance was provided. The failure mileage was approximately 98,000.
My water pump went out on my 2021Q7. The car had 57271 miles on it. I looked up the Vin and it is not covered in the class action lawsuit however, my model and my year comes up but not my Vin. I feel a water pump should last until 100,000 miles.
The recall involves the virtual cockpit instrument cluster. Audi requires the use of the vehicle’s USB port to complete the update. However, my USB system is not functioning properly. •The Issue: Audi has refused to perform the recall because of the inoperable USB. They have stated that without the USB, they cannot install the update. They are not offering any alternative method or solution to ensure that this recall is completed. •Why This is a Concern: A recall is issued because of a safety-related defect. The manufacturer is obligated under federal law to remedy the defect at no cost to the owner. By refusing to provide a solution beyond requiring a functioning USB, Audi is failing its duty to correct a known safety defect. This leaves me driving a vehicle with an unresolved recall. •My Position: It is unreasonable and negligent for Audi to deny responsibility simply because the recall requires a USB port that is not functioning. The recall repair should be performed regardless, whether through replacement of the port, use of alternate diagnostic tools, or another approved method. By refusing to act, Audi is leaving my vehicle unrepaired, unsafe, and in violation of recall compliance obligations. Requested Action: I respectfully request that the NHTSA investigate Audi’s handling of this recall and require them to provide an effective remedy at no cost to me, in accordance with federal safety recall requirements.
El carro fue comprado en febrero 2024 en greenway ford inclui un paquete de cambio de aceite,rotacion de llantas y cambio de los limpiabrisas.esto ha sido un dolor de cabeza. cada vez que se le realiza el servicio sale con la luz del ingenier prendido, en la computadora de auto zone aparece TURBOCHARGER INTERCOOLER(P0299).

On [XXX], I experienced multiple failures of core safety systems in my 2021 Audi Q7 that put my 17-month-old child at serious risk and exposed critical flaws in how the vehicle’s systems operate and record events. On [XXX], the pre sense automatic braking system suddenly engaged while I was driving approximately 35 mph on a clear, empty suburban road. There were no visible obstructions, no warning lights, and nothing recorded in the vehicle’s logs. This occurred less than 48 hours after the vehicle had received recall-related software updates and routine service at an Audi dealership. Prior to that service, the vehicle had no history of mechanical or safety issues. The following day, the keyless entry and anti-lockout system failed. I placed my toddler in his rear-facing car seat behind the front passenger seat and set our baby bag—with the key fob inside—on the rear seat. After closing the door and walking to the driver’s side, the car unexpectedly locked. The fob and my child were both inside. The outdoor temperature was over 90°F. I attempted to open the vehicle and then to break the window with tools, without success. After approximately seven minutes, I broke the driver’s side window with a sledgehammer and removed my child from the car. The car alarm eventually activated, but no lock-in event, key fob error, or warning was recorded. The vehicle was inspected by the dealership twice and Audi Corporate engineers once. Audi confirmed faults in the emergency call module, comfort system, rear lid sensor, and parking sensors. However, they could not reproduce or explain the braking event or lock-in failure. Audi confirmed that the vehicle should not be able to lock with the key inside, and they do not know why it did and are unable to guarantee the safety feature will work in the future. The vehicle has not been driven since. The failure of both safety function and system visibility placed my child in danger. I am requesting a safety investigation. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
I am reporting a severe defect in my 2020 Audi Q7 involving “coolant migration” due to a faulty water pump, a known issue in Audi models (Q7, S4, A6, 2013–2022). This poses critical safety risks due to sudden failure with minimal warning. My out-of-warranty Q7 showed minor coolant fouling near a solenoid, with normal coolant levels and no fluid added. The dealer quoted ~$6,000 to replace the water pump and vacuum system. This defect is highly dangerous due to: Sudden Power Loss: Coolant in the vacuum system impairs solenoids and lines, disrupting engine/turbo function. This can cause abrupt power loss, risking loss of control in traffic or at high speeds, potentially leading to collisions. Catastrophic Overheating: A failing water pump may halt coolant circulation, causing rapid engine overheating without warning, risking sudden engine shutdown and stranding drivers in hazardous conditions like highways. Brake Assist Failure: The vacuum system powers the brake booster. Contamination can reduce braking effectiveness, increasing pedal effort and stopping distances, heightening collision risks in emergencies. Emissions Control Issues: Coolant fouling affects PCV and EVAP systems, causing misfires, stalling, or increased emissions, potentially triggering check engine lights and compromising engine stability. Undetectable Progression: The defect often shows no clear symptoms or warnings until severe damage occurs. My vehicle had only minor fouling that could only be detected by visual inspection, yet extensive repairs were needed, indicating the issue’s stealthy nature, which prevents timely driver intervention. Systemic Issue: Forums and a class-action lawsuit confirm this defect across Audi models, yet owners face high repair costs post-warranty. This defect endangers drivers and others by risking vehicle failure, impaired braking, and unstable performance. I urge NHTSA to investigate and mandate a recall or extended warranty.
The instrument cluster failed as was reported in a previous recall. This failure was caused by a hardware problem which was fixed via a software update. Unfortunately, the hardware (instrument cluster) has already been compromised and warning lights are all lit up and some warnings aren't working and the instrument panel still goes blank when driving.
The contact owns a 2021 Audi Q7. The contact stated the vehicle was repaired under NHTSA Campaign Number: 25V201000 (Electrical System); however, the repair failed to prevent a failure from occurring. The contact stated that two days after the recall repair, several unknown warning lights illuminated. In addition, the contact stated that after refueling the vehicle, the fuel gauge failed to provide an accurate reading for the fuel. The contact stated that the check coolant and temperature warning lights were intermittently illuminated. The local dealer was contacted, but the vehicle was not diagnosed or repaired due to the cost. The manufacturer was made aware of the failure. The failure mileage was approximately 105,000.
The contact owns a 2021 Audi Q7. The contact stated that while operating the vehicle, the instrument cluster display was inoperable and could not be viewed by the driver. During the failure, the driver was unable to view the speedometer and turn signals. The vehicle was taken to the local dealer, who diagnosed that the instrument cluster was faulty and needed to be replaced. The vehicle was not repaired. The manufacturer was not notified of the failure. The contact was informed that the VIN was included in NHTSA Campaign Number: 25V201000 (ELECTRICAL SYSTEM). The contact stated that the vehicle had experienced the failure listed in the recall. The failure mileage was 52,000.
Both of the screens went blank while I was driving and the top one showed this: ENGINEERING +Update + Activation keys +Version information +Reboot to normal mode
In correspondence with recall number 25V201, the Virtual Cockpit display would go blank while driving, hiding all driver assistance indicators/instruments. Unable to verify engine speed unless looking at the heads up display, but adaptive cruise control/forward collision warnings won’t display. Upon parking and restarting vehicle, the display would work, but will intermittently go blank after some time while resuming driving. Called local dealership and they are aware of issue but since a repair is unavailable, out of pocket costs would be incurred. There have not been any inspections but I’ve scanned the vehicle for error code B200049, documented in previous Audi TSBs related to the virtual cockpit display issue.There were no warnings or indications, prior to the event which occurred less than a week after recall number 25V201 had started.
There is a recall for my issue from Audi 90VC. The “remedy” is a software update that a previous dealer and Audi field techs say willl not fix my issue. It’s a hardware issue. The remedy provided for the recall is a facade and doesn’t fix the root cause of the issue. I’m one that actually have the symptoms of the cockpit failed (completely blank screen) but yet Audi is telling me I have to pay to have this safety recall/issue fixed.
So models which have digital cockpits that were produced before July 2021 are faulty and the screen goes black. I was on the I95 when the display was gone and I didn’t have a speedometer. The manufacturer is already aware and accepts there’s a issue but doesn’t have a recall.
Driving on highway at 70 mph and high engine temp light came on. Said to pull over and continue to run car until temp decreased. I got over as quickly as I could ( no more than 1/4 of a mile) and sat on side of PA turnpike as engine cooled. I was at bottom of an exit ramp. I slowly proceeded up the ramp and warning came on again and red temp light reached again. I pulled right into the gas station at top of TP exit ramp. It still said to continue to run the car. I sat with my son in the car and ran the car in the shade. The temp was decreasing and then all my electrical lights came on, yellow battery warning light on and then suddenly the red battery light and all systems failed. Car turned off. Called AAA to take to my mechanic as Audi was a 3 hour wait for a tow and 3 weeks for service appointment with no loaners available. My certified mechanic said water pump completely dislodged. He replaced water pump, thermostat (which was already replaced bc it failed in year 2 of ownership). After repair, 48 volt battery would not take a charge. Assumed faulty alternator and/or battery. Alternator was already replaced once at year 1 as car died while driving as well. We had car towed to audi and they are reporting known issues with water pump but not issuing recalls. Also known issues with alternator repair parts that were used in year 1 but no warning to consumers. They are diagnosing problem now and if alternator and subsequent battery issue, it will be covered but not if battery issue comes back as electrical in nature.
I continue to smell a foul, moldy odor almost every time I turn on the air conditioner or heater. It has been a problem since I purchased the vehicle in August of 2024. I took the car back to the dealer from which I purchased it FOUR times. They finally “fixed” the issue by clearing out some tube. However, the issue has presented itself again. I had the cabin filter replaced last week to no avail. It still smells awful. I definitely cannot use the heater. This potentially presents a health issue and needs to be fixed.
During commute dash lit-up with "central indicator light", "Vehicle starting system; malfunction! Please contact Service" warning notice, "Audi pre sense" yellow-lit dash warning light, yellow-lit battery warning light that alternated to red-lit battery warning light. AC automatically shut off, radio shut off, was able to limp vehicle home. Restarting the vehicle gave a "Battery low voltage" reading then a vehicle failure "immediately turn vehicle off when safe" message followed by the "Vehicle starting system; malfunction! Please contact Service" warning notice. Towed Audi to local Audi shop in Charlottesville, VA, where it was diagnosed with starter generator failure, part was reportedly ordered on 27 July 2024; no indication as to whether the part has arrive at Audi shop. No details on the battery as of 01 August 2024.
Water pump started leaking at 55K miles resulting in low coolant level. Vehicle was inspected by the dealer and confirmed that replacement is required.
Safety recall for backup camera has tried to be repaired 3 times now and not fixed.
Twice in the last 2weeks the vehicle has an electrical system failure while on expressway. This is dangerous as the message tells you to immediately stop driving. On a highway this is a serious hazard.

My car first had a warning “Electrical system: malfunction! Please contact Service.” I made a appointment at my Audi dealership 2 days later, but the next day i got more warnings. “Automatic start/stop system: malfunction!” then my power steering was not working. I decided to drive straight to the service department that afternoon, but never made it. In rush hour traffic on a busy street, my Q7 started beeping every warning - “Electrical system: malfunction! Safely stop vehicle”, “Drive system: malfunction! Stop vehicle safely” and the vehicle decreased speed then abruptly turned off. I was so scared that I would get hit by the traffic zooming around me. It wouldn't go into neutral and my parking brake was engaged blinking. I put on my hazard lights and called 911 for traffic assistance while sitting in my car. I was able to safely exit and after calling Audi, I could get my car into neutral and move it off the busy street with the help of some good Samaritans. I had the car towed to Audi. The service department said they have seen this a handful of times and that it's a problem with the accelerator/generator.
Car displayed electrical Issue when driving daughter to school. Let husband know but was only a yellow warning and had a full day planned. I unfortunately assumed it was just a battery issue and continued with my day, but made an appointment at Audi for repair. I drove to my next appointment and the yellow warning moved to a red warning but I was 20 minutes from home. I called my husband and warned him I’d probably not make it all the way home, I made it another 10 miles and then it completely turned off on the freeway, I was prepared and had stayed in the right lane thinking this could be coming. Towed the car to Audi, they are ordering parts and warned it could be 4 weeks before I got my car back. The “generator” needs to be replaced.
Per carfax, my preowned 2021 Q7 with 9k miles has had several visits to audi dealerships. The car was eventually used for a buy back. That said, Audi USA "fixed" the vehicle and sold it. The car is NOT fixed and as the new owner I've waited 2 weeks after buying this car to drive and possess it only to have the battery warning light back on the dashboard after taking possession today. The car was previously at an audi dealership before it was cleared to be shipped to me. It seems Audi is unable to fix this car. I will need to tow it now to another audi dealership as I'm afraid the car will lose all power during any attempt to drive it back to a dealership.
Battery light on dash red and yellow abs light on.. multi Electric faults. On my massage board and car died on the road.
Forward Sunroof implosion into passenger compartment. No visible outside debris or projectiles. Vehicle underway, speed approximately 55mph , weather clear, moderate winds, traffic heavy. No accident, minor abrasion injury.
Starter Generator Failed on 10/12/2023 while the car was being driven. Warning received was "Electrical system: Malfunction! Safely stop vehicle" There are multiple reports online of people experiencing similar problems and have had recalls. We never had a recall and this could have caused a fatality. We feel Audi has been negligent.
While driving, vehicle flashed red error codes for an electrical system malfunction and indicated that the vehicle should be stopped as soon as possible. As part of this failure, the auto start/stop for the vehicle became disabled. Vehicle was towed to Audi dealer, and after sitting on the lot for a week, the dealer confirmed that the starter generator for the 48V mild hybrid system failed.
on Sep 17 2023 my wife was driving her Audi Q7. which has 25,780 miles. She drove to a parking lot for a hiking trip, pressed on the brake and the car instead of stopping accelerated. She kept trying to press the brake, however the car did not stop until it hit a tree. The car has been towed to our house and it is not driveable. The car has not been inspected yet. I plan on calling the Audi dealer on Monday, Sep 18th. No lights appeared before the incident.
While driving with my 4 year-old daughter a notification appeared on the driver display that there is an “Electrical Malfunction” and to call the service department. A few minutes later, while actively driving on the same busy road in my town, the vehicle completely turned off, including the power steering and ABS breaks. I was stuck in the middle of a busy intersection with no hazard lights and no ability to even shift the vehicle into neutral to move it. I was genuinely concerned for my safety and the safety of my daughter, as we were stranded in the middle of a busy intersection during rush hour. It was a harrowing experience to say the least. Eventually we had the vehicle towed. When I called Audi, they informed me that they suspected it was the “starter generator” and that they were aware of the issue, but this was the first I had heard of it. They subsequently confirmed that it was the starter generator and are less than accommodating.
The contact owns a 2021 Audi Q7. The contact stated that while driving at unknown speeds and making a left turn, the vehicle jerked and stalled. The contact was able to pull over into a parking lot. There was an unknown red message displayed regarding the pressure sensor. The driver sustained injuries to the head, arm, neck, and back, but medical attention was not provided. The contact called the local dealer, but the vehicle was not diagnosed or repaired. The manufacturer was not contacted. The failure mileage was approximately 26,789. The VIN was not available.
The seat belt has now come unlocked from the locked position multiple times without unbuckling the seat. This is an issue because it's the seat belt used to install an infant car seat, so the car seat is not locked into place, which could be a major issue in the event of a crash. The seat belt retractor has randomly unlocked multiple times after being locked into place. The car dealership was unable to replicate the problem, but it has since occurred multiple times at home.
The right rear seat belt locking retractor, which was locked when I put my son in his car seat, became unlocked in motion during our trip while his car seat was in use. I check the lock each time I place him in his car seat, and it was locked at the beginning of our journey. Having an unlocked safety belt puts a child at risk since their car seat can't be properly secured with an unlocked safety belt. The retractor had worked prior to this instance since I started using it with our car seat 3 months ago. I have reached out to the Audi dealership and have not heard back.
Electric malfunction signal all sudden appears while driving and engine start malfunction.
285/40R21 At the end of a Vermont ski trip, left to return home on the morning of 3/15/23 at approximately 8am. Outside temperature was approximately 30 deg F and it was snowing. Due to partially snow-covered roadways, speeds were limited to 35-40 mph. After driving for approximately 20 minutes, the tire pressure warning indicated, followed approximately 30 seconds later by catastrophic sidewall failure and complete tire deflation. The rapid loss of tire pressure combined with the slippery road service was extremely dangerous and we were very fortunate in steering the car to a safe parking area without losing control or colliding with other nearby vehicles. Audi roadside assistance was contacted and the car was towed to a local dealer. Upon inspection, the failed tire (original OEM supplied) showed no evidence of puncture, only catastrophic failure of the sidewall. The failed tire is being held at the dealer in Rutland, VT. Because of a similar failure on 11/12/22 with another of the (4), original OEM tires, all (4) tires were replaced with Pirelli tires as it was no longer safe to continue driving on any of the original Continentals.
The contact owns a 2021 Audi 7. The contact stated that while operating the vehicle electrical warning messages would suddenly display. One while the wife was driving approximately 20 MPH the vehicle suddenly shut off in the middle of the road. The vehicle was later towed to the local dealer who diagnosed that the alternator was faulty and needed to be replaced. The vehicle was not yet repaired. The contact was informed by the service advisor that the failed alternator was a known issue and the manufacturer had extended the warranty for the alternator and the replacement alternator was on a ten-week delay due to the high demand for the part. The manufacturer was notified of the failure. The failure mileage was 27,000.
Electrical system malfunction causing the car to fail Steering Parking brake Vehicle lights Vehicle starting system Stabilization control
Multiple warnings indicating to contact dealer (Lane departure, adaptive cruise control, collision avoidance, electric system malfunction, steering malfunction) then a few minutes later transmission failure and engine failure imminent.... attempted to move out of traffic. Luckily, I made it to the right lane before the steering shut down, then the transmission failed (stepping on the gas caused the engine to rev, but no power was delivered to the wheels), and last the car completely died. Had to have it towed to dealership. Dealership confirmed that the starter/generator failed.
My 2021 is having an issue with the starter generator. Apparently this is a issue with many Audi's
At approximately 3:15pm CST on Friday, January 13, 2023, several electrical system warnings appeared, and the vehicle stopped in the middle of the street. We were able to restart the vehicle twice, but only able to drive it about 10 feet to move it out of the middle of the street. We then had the vehicle towed to the dealership for repairs. The dealer has told us that the electrical generator failed and needs to be replaced. It should be available for inspection, if needed. No other party, such as police or insurance, has inspected the vehicle. My safety and the safety of others was put at risk, because the vehicle died in the middle of the street with little warning and could only be moved a short distance from there. Pictures of some of the warnings are attached.
While driving the vehicle, error messages began appearing on the in-panel dashboard display. At first, a yellow/orange battery icon appeared with the message "Electrical system: malfunction! Please contact Service". Within an hour, the car experienced another electrical system malfunction (red battery icon appeared with the message "Electrical system: malfunction! Safely stop vehicle") along with a host of other error messages (Brakes: malfunction, Steering: malfunction, Parking brake: malfunction, Vehicle lights: malfunction, Stabilization control (ESC/ABS): malfunction, Drive system: malfunction, Transmission: malfunction). The car was undrive-able at this point, coasted to a stop and could not be restarted while on an active roadway. The car had to be towed to the dealership, where it still remains today. * Components or systems malfunctioned: Electrical system, brakes, steering, parking brake, vehicle lights, stabilization control (ESC/ABS), drive system, transmission. It is available at the Audi dealership service location for inspection * My safety was put in significant danger due to the car shutting down on an active roadway with no control over the vehicle. * The problem has been confirmed by the dealer. * The vehicle has been inspected by the dealership service center but not by police or insurance representatives. * Many warning lamps and messages appeared within an hour of the car becoming inoperable.
Driving about 25 mph power of steering wheel was lost, steering became very hard. I stopped, no accident. Not reported yet. Messages appeared: 1. Steering: malfunction! please stop vehicle 2. Audi pre sense 3. Lane departure warning 4. Emergency assist
Electrical failure indicator lit up. I was on my way to the dealership service center. Within 10 minutes of driving, the car completely shutdown right at a busy intersection and before an active railroad crossing. Tow truck was called by the police as the car was not starting and therefore undriveable.
