Electrical System Problems of Audi Q7 - part 1

The vehicle has a recurring electrical failure involving the camshaft position sensor circuit (dtc p0365). The sensor itself is functional, but the wiring harness leading to the sensor develops internal copper fatigue due to a design flaw in the factory routing. The harness is bent tightly behind the passenger-side cylinder head, causing vibration-induced internal wire breakage that is invisible externally. This failure is well known to Audi dealers and has been reproduced and confirmed by multiple service centers. The problem is not caused by the sensor, plug, or engine components. It is caused by the wiring harness design, which repeatedly fails in the same 6–10 inch section. The defect causes intermittent loss of camshaft signal, illumination of the check engine light, and inability to pass emissions. Repair requires cutting open the harness and splicing in new wire, costing approximately $700–$1,200 each time. This is a repeated electrical defect caused by poor harness routing and inadequate wire durability. This issue affects safety indirectly because the vehicle cannot reliably report camshaft position to the ecm, and the failure is unpredictable. The defect is widespread among vehicles using the same engine and harness design.

The contact owns a 2021 Audi Q7. The contact stated that the instrument cluster display had become blank and failed to operate as intended. The failure prevented the contact from viewing critical vehicle information, including the speedometer, fuel gauge, and turn signal indicators. The vehicle was taken to a dealer, where it was diagnosed that the instrument cluster failed and needed to be replaced. The contact associated the failure with NHTSA campaign number: 25v201000 (electrical system); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 90,000.

My 2017 Audi Q7 with the 3. 0t engine has experienced repeated engine/ignition system failures. The vehicle displays a "system malfunction" warning light accompanied by shaking and stalling. This same malfunction has occurred at least 3 separate times over the past few years. Each time, a repair shop diagnosed and replaced faulty ignition coils, and the vehicle ran normally for a period of time before the identical malfunction returned. The vehicle is currently inoperable due to the most recent occurrence. This creates a safety risk because the stalling and shaking can occur while driving, with no clear warning beyond the malfunction light appearing at the same time as the symptoms begin. A stall or loss of power while in motion, especially in traffic or on a highway, could lead to a collision. The problem has been confirmed and repaired multiple times by an independent european auto repair specialist, who stated this is a known, recurring issue with this engine/model. The vehicle has not yet been inspected by the manufacturer directly. Separately, the vehicle has also developed excessive oil consumption, requiring approximately 2 gallons of oil added roughly every 6 weeks, with the frequency increasing over the last 2 months. I am uncertain whether the oil consumption and the recurring coil/ignition failures share a common root cause, but both issues are ongoing and unresolved. The vehicle and its components are available for inspection upon request.

On startup, the instrument cluster (Audi virtual cockpit) takes an abnormally long time to illuminate. When it does come on, the check engine light and multiple other warning indicators are illuminated. First noticed about a month ago when the panel with the speed indicator wouldn't light up or took a long time to illuminate. I took the car to three dealerships before Audi mentioned that this is a manufacturing issue. The vehicle was taken to jim ellis Audi, marietta, GA (repair order 106862u) in August 2026. The technician's diagnostic notes recorded a fault described as "control module for instrument cluster — optical data bus — no communication. " the dealer referenced an internal technical service bulletin describing an intermittent hardware defect in the Audi virtual cockpit logic module, attributed to a manufacturing/semiconductor issue at the supplier level. Per the TSB, if the instrument cluster's production date is before February 1, 2025, the cluster must be replaced. The dealer quoted $3,093. 81 to replace the instrument cluster assembly. I am aware that NHTSA recall 25v201 (Audi internal number 90vc) covers 2021 Q7 vehicles for a related virtual cockpit shutdown defect, remedied with a free software update.

My independent repair shop has just diagnosed a coolant leak weeping from the vacuum line connection at the water pump; they referred to this problem as “coolant migration”. As documented extensively by Audi in technical service bulletin 19-23-45 (2070349/2), this indicates an internal seal failure of the water pump, causing pressurized engine coolant to migrate directly into the vehicle’s vacuum system. While I understand that my vehicle is technically past its 4-year factory warranty timeline, a mechanical failure of this nature at just 43,000 miles is highly premature and points to a known manufacturer design defect rather than standard wear and tear. More importantly, this defect poses an immediate, severe safety risk. Because the vacuum system directly services the power brake booster, the migration of coolant into these lines risks catastrophic contamination of the braking system. This results in a stiff brake pedal and compromised vehicle stopping ability. I am deeply concerned about operating this vehicle with an active, manufacturer-acknowledged safety hazard affecting my brakes. At this time, I have not had this problem confirmed by the dealer, but plan to in the next week. The vehicle it available for inspection upon request.

My rear backup sensors have fallen out of my vehicle and the dealership wants to charge me $200. 00 to diagnose the problem. All they need to do is reattach the sensors which were originally put on the vehicle with double sided adhesive tape which is a poor design. I cannot afford this $200. 00. This is a big safety concern because I rely on those sensors when backing up. Can you help me?.

While parked in my residential garage with the engine shut off and car door closed, the vehicle suffered an un-commanded rollaway incident due to a suspected defect in the electronic parking brake or automatic-park transmission software. The vehicle was completely stopped, the driver exited the vehicle and the driver's door was closed. Moments later, the vehicle shifted out of its parked state or failed to hold, rolling backward down the driveway and colliding with a basketball pole in the driveway, causing vehicle damage. No warning chimes or dashboard alerts were observed prior to exiting. The vehicle's electronic failsafe to automatically engage 'park' upon the door opening failed to secure the vehicle.

We were in my vehicle. An Audi Q7 2021 driving in the highway ([xxx]) headed to ohio from florida and during a traffic jam all the sudden my car stopped and will not react and was “stucked in park” and transmission malfunction, parking brake malfunction, start/stop system malfunction codes popped up all at once. So scary and cars started to move and we couldn’t. Luckily we were able to get to safety and check battery but this shouldn’t happen to anyone as could cause irreversible damage to human life.

I drove home after shopping, opened my garage door by remote, and pulled into the garage. I placed the vehicle in park, and shut off the engine via push button. I retrieved my purse from the passenger seat and exited the vehicle. I exited the vehicle with the intent of retrieving my shopping bags from the rear hatch. As I walked towards the rear of the vehicle I noticed my next-door neighbor had stopped at the end of my driveway with the driver’s window down. I did not make it to the hatch door and instead walked to the end of my driveway. [xxx] was the only occupant of the car. He was the driver. We started talking for several minutes with my back to the garage the entire time until neighbor hollered “[xxx] is going on?” the last thing I remember is my Audi Q7 slamming my body into one or both vehicles. I was thrown to the driveway with my right foot wedged under the Audi Q7’s driver’s side rear tire. I worked my foot free from my shoe and got myself up to a standing position with clear pain in my back and foot. Vehicle rolled on its own with transmission in park. Note: ~vehicle transmission was in park on a flat surface when I exited vehicle with car keys ~ I was stuck by vehicle, vehicle in question also struck another vehicle ~not to my knowledge ~none of the agencies or companies have inspected vehicle ~no warning lights information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

4/30/26 I came home, parked in my driveway, got out of the car and opened the left back door to get my handicapped son out of the car. He wanted his talker from his backpack(he is nonverbal), so I sat next to him on the back seat and gave him the talker. Then I got out of the car and helped him to get out, closed the left rear door and turned towards my house holding his hand. At that point my mother who got out of the house because she saw us coming started yelling that the car is moving. I jumped, opened the driver door put my right leg inside trying to stop it but by then the car had already hit my fence right where we have a gate. The gate unlatched and opened and the car got then stuck in the opening pinning my left leg which was still on the ground against the door and the car as the car itself was pinned inside the fence opening. Eventually the gate completely gave in and the car continued to slowly move forward into my backyard, I got my right leg out while I saw the car rolling and taking down a shed and stopping in my tree. My leg was hurting very badly so I called 911. I still have some minor discomfort but had a large hematoma and significant pain for 2 weeks. Then the car had a failure to start several times on two different days on one day needing 15 attempts to start. I took the car to the dealer after the first incident and they said no codes and car is fine. I took it again after the car didn’t start and they mocked me. There was 15000 in body damage. I am a doctor and discussed with 5 different patients that are mechanics and they all said this car has clearly a defect and I should not be driving it.

While trying to park 2025 Q7 the vehicle accelerated without warning and adaptive cruise flashed quickly then disappeared. I was the driver and had a passanger along. This incedent repeated itself within 30 mins. I am not comfortable driving the car. .

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 am having issues with my vehicle ( Audi 2017 Q7)that matches Audi recall 97cb NHTSA campaign number 16v642000 regarding the side marker light software malfunction. While my VIN is not currently showing as open on a recall my vehicle is experiencing the marker lights failure. My vehicles mfd date is 05/16 which is in the dates of the recall 97cb but is for some reason excluded from the recall. I have had the vehicle at the Audi dealer to check on the problem. They have had the vehicle two different times totaling 15 hours and are unable to find a problem. They refuse to provide the recall remedy because my VIN is not currently flagged. My VIN is [xxx] . I am requesting my VIN be added to the 97cb NHTSA# 16v64200 my case # with Audi is xxx rep is susan . Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Getting error message that the "front left side marker light defective". The light appears to be operational. Service shop looked to read the errors with odb2 and both light modules (left and right) are not communicating any info. In same time the warning in dashboard is continuous and can impede gauges visibility during night. Audible warning noise can also activate at random times. Searched for this issue and Audi recalled some models for electrical software issue but many users outside the current recall report this same issue. Please expand the VIN numbers for the recall action for safety.

The starter in my Audi Q7 2019 failed and the car would not start. I was parked in my garage and manually had to put the car in neutral using the tool provided in the trunk and push the car out of the garage until a flatbed tow truck was able to take my car to the shop. If this happened elsewhere, I could have been stranded without the ability to start my car. My car was towed to a certified shop where they confirmed the failure and made the repair by installing a new starter.

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.

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.

Left front side marker light faulty. Is the warning on the dashboard - I have noticed there is a recall I believe 2017 2018 for the same part and this is on a 2019 so it's obviously the part it actually says if there's a software fix.

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.

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.

While driving, the vehicle’s infotainment system suddenly froze and then rebooted on its own. During the reboot, the display was unavailable for several minutes, causing loss of access to navigation, vehicle status information, and warning messages while the vehicle was in motion. This occurred without warning and distracted the driver while driving, creating a potential safety risk.

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.

I own a 2025 Audi Q7 and have experienced repeated malfunctions related to the vehicle’s driver assistance and safety systems. The vehicle frequently displays warnings such as “driving assist not available” and other safety system errors. These issues started while the vehicle was still relatively new and have continued intermittently. The warnings appear while driving and indicate that important driver assistance systems are not functioning properly. I have taken the vehicle to the dealership multiple times for inspection. However, the dealership often reported that they could not duplicate the problem or that no fault codes were found. Despite this, the warnings continue to appear and the problem remains unresolved. Because these systems are related to safety features such as emergency braking and driver assistance, I am concerned that the malfunction could create a dangerous driving situation. The vehicle has multiple documented service visits and I also have video evidence showing the warnings when they occur. I am reporting this issue because the malfunction involves critical safety systems and has not been properly resolved by the dealership.

First incident [xxx], in columbia SC driving in parking lot on post, approx 10pm, blocking traffic. Car shut down and mmi disappeared. After approximately 20-30 minutes car started, still no screen. I was able to drive it. Next day, rebooted per google, took to dealership who said I should make sure I used premium gas. When I said I did I was told to be careful which gas station I bought it from. And since the screen was back up they couldn’t do anything. I called the corporate office who had them run a full systems check. All with mmi was well until [xxx] at [xxx]pm. Driving in columbia SC screen disappeared again but car did not stop this time. I called dealership who told me to press the volume button until it rebooted. It didn’t work. I was told to bring it in. The Audi app sent me a headlight assistant malfunction warning! message at 7:44pm also, same evening as the mmi incident. Copy of current screen and 10/24 service receipt. This is a dangerous situation as someone almost hit the back of my car during the first incident since the stop was so sudden ([xxx]) I was blocking the driveway and cars had to backup and detour in a small dark area. Losing mmi while driving is a distraction. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Yesterday I bought a 2019 Audi Q7 and today I get a warning light stating my right parking lamp is defective. Upon checking the light I found that it was on and working. Upon researching the issue I found that there are numerous complaints on 2017 and 2018 models of the same vehicle, for the same issue. Dealership stating it is an entire right headlight replacement to the tune of over $ 2500.

I am filing a complaint concerning serious safety risks associated with my 2020 Audi Q7 (VIN: [xxx] ) purchased as a certified pre-owned vehicle from Audi dominion san antonio. It is currently under service at Audi central houston, where multiple concerning events occurred. Timeline and issues: - initial diagnosis identified a fire-damaged electrical harness, estimated at $1,400 for replacement. - after repair attempts, the vehicle began smoking, and the diagnosis expanded to include additional compromised electrical lines. The revised quote skyrocketed to $4,700 (later reduced to $3,100). - after nearly two months in service, I was informed that the ac compressor is now deemed "bad" due to debris from the harness, an issue not mentioned in previous inspections. Safety concerns: 1. Inconsistent diagnosis: there was no mention of compressor damage during initial assessments. This late-stage discovery indicates negligence or potential additional damage during servicing. 2. Risky ac activation: a technician attempted to clean the compromised ac compressor and activated the system, a procedure that is dangerous given the debris. This could lead to refrigerant leaks and electrical shorts. 3. Conflicting statements: Audi central houston claims the compressor was previously damaged but also attempted to restore it. Such contradictions raise serious concerns about service integrity. 4. Certified pre-owned credibility: the emergence of these costly issues questions the reliability guarantees of vehicles sold under Audi's certified pre-owned program. Given that the vehicle began smoking shortly after being parked and had not undergone prior electrical work, I underscore the severe safety risks posed by potential electrical fires and undisclosed damage. These issues could endanger lives and property if not properly addressed. I strongly urge Audi USA and the NHTSA to investigate this matter for potential technical service bulletins or recalls, especially fo information redacted pursuant to the freedom of information a.

The contact owns a 2017 Audi Q7. The contact stated that while driving at an undisclosed speed, the driver's side marker warning light illuminated. The vehicle was taken to an independent mechanic with a failing driver's side marker. The contact was informed that the driver's side marker needed to be replaced. The vehicle was not repaired. In addition, the contact stated that while driving at night, the failure was a safety issue. In addition, the contact stated that the dinging from the sensor was a distraction. The manufacturer was made aware of the failure, and a case was filed. The contact referenced NHTSA campaign number: 16v642000 (electrical system, exterior lighting); however, the VIN was not included in the recall. The contact was advised to contact the NHTSA hotline to report the failure. The failure mileage was approximately 96,000.

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 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 2017 Audi Q7. The contact stated that while driving at an undisclosed speed, the message "side marker light fault detected" was displayed. The contact stated that after a visual inspection, the contact became aware that both side marker lights were illuminated. The vehicle was taken to the dealer, who diagnosed a failure with the side marker light assembly. The vehicle was not repaired. After investigating the failure, the contact related the failure to NHTSA campaign number: 16v642000 (electrical system, exterior lighting); but the VIN was not included. The manufacturer was notified of the failure, a case was opened, and the contact was referred to the NHTSA hotline for assistance. The failure mileage was unknown.

To whom it may concern, I am writing to formally report a serious and recurring safety issue involving my 2018 Audi Q7. The vehicle has experienced repeated drive system malfunctions that result in sudden loss of power, reduced acceleration, and warning messages on the dashboard such as “drive system: malfunction” and “electrical system failure. ” these incidents have occurred while the vehicle was in motion, creating a hazardous situation for both the occupants and surrounding drivers. In my case, the vehicle unexpectedly lost power while driving at highway speeds, forcing me to maneuver to the shoulder with diminished control. This sudden malfunction is unpredictable and could easily result in a collision or serious injury, especially in high-speed or high-traffic conditions. Upon researching this issue, I found that numerous other 2018 Audi Q7 owners have reported similar problems. These complaints consistently cite the same symptoms, including sudden deceleration, electrical system errors, and power steering failure. It appears to be a widespread defect that may warrant a recall or further investigation by the NHTSA. I urge your office to investigate this matter promptly to prevent potential injuries or fatalities. I am willing to provide service records, diagnostic codes, photos, or any other documentation that may support this complaint. Thank you for your attention to this serious safety concern. I hope the NHTSA will take appropriate action to ensure the safety of all drivers affected by this defect.
