Service Brakes Problems of Audi Q5 - part 1

Mileage at time of incident: approximately 4,000 miles date of incident: xxx location: [xxx] incident description: my vehicle was in neutral while going through an automatic car wash, as instructed. When the exit signal indicated it was clear to proceed, with my foot on the brake, I shifted into drive. The vehicle accelerated on its own, without corresponding accelerator pedal input, and struck the building adjacent to the car wash. The vehicle did not exit the building on its own, so I shifted into reverse. The vehicle again accelerated on its own and struck a structural beam. I applied continuous pressure to the brake pedal throughout the incident. The vehicle did not respond immediately, but the brakes eventually engaged and brought the vehicle to a stop. The vehicle's rear obstacle-detection and automatic braking sensors, which normally engage under similar low-speed reversing conditions, did not activate at any point during this incident. The airbags also did not deploy after the vehicle struck the building. Video footage of the incident shows the vehicle moving at low speed with no visible braking response until the vehicle came to a stop. Police and fire department personnel responded to the scene. No injuries were reported. Property damage occurred to a vinyl fence, an adjacent building, and an interior wall of a business inside that building. I requested that the vehicle's event data recorder (edr) be reviewed by the dealership/manufacturer prior to any repairs, to determine throttle position, brake switch status, and sensor activity at the time of the incident. As of this report, Audi sent an engineer to inspect the vehicle on xxx and has since provided me with a rental car. I am still awaiting the results of that inspection. Components involved: engine/motor, electronic throttle control, service brakes, parking assist/sensors, forward collision/automatic braking system I am filing this report because I was genuinely afraid for my safety information redacted pursuant to the freedom of information act (.

I was pulling into (my usual) handicapped parking space, at a slow speed. As I approached the curb my brakes did not respond to stop my car. Not only did my brakes not respond, the car actually sped up - going up the curb and hitting the handicapped sign pole. The pole broke and stopped my vehicle! I was afraid my (out of control) vehicle would keep going through a store front - it did not. Folks gathered around- thinking I had put my foot on the gas . I did not put my foot anywhere except on my brakes …which went ‘mushy’ . Would not stop my vehicle. My research has found similar incidents reported by other drivers. I am not alone. Of course the dealership could not reproduce the incident. But they did suggest many other services for a car with 60,000 miles. The Audi dealership took no responsibility for the incident. There was a recall on the master cylinder that was supposedly handled before I took delivery of the vehicle in January 2019. Audi denied that anything was currently amiss with my master cylinder. There was a warning message when I tried to start my car about a week before. Because it made no sense - like your tires are low - I dismissed it as just a check engine light ??????? I honestly can’t remember what that ‘odd’ warning said??????? I’m not alone in reporting this - I’m almost afraid to drive my car??.

I wrote Audi to request escalation of an unresolved issue involving my 2018 Audi Q5, related to safety recall 90s9 (NHTSA campaign 21v947000) for the gateway control module. Summary of the issue: my vehicle recently experienced a complete gateway control module failure due to water intrusion. I lost steering and brake assist warnings while driving, and the vehicle would not restart after being pulled over safely. It was towed first to the nearest Audi mechanic who diagnosed the issue as recall 90s9. We then contacted Audi memphis for inspection by them since it was a recall issues and paid a 2nd towing charge. Audi memphis (owned by gossett motor cars) said they could not do anything until they looked at the car. I have since obtained a copy of the original repair order from when recall 90s9 was performed on my vehicle. The vehicle at the time of recall repair was owned by my mother. The recall requires two remedies: (1) installation of a protective cover over the gateway control module, and (2) sealing of an underbody seam on vehicles produced before September 2021. The repair order shows a technician comment reading "insf" next to the seam sealant line item, which indicates the sealant application was noted as insufficient at the time of the original recall service. Despite this documentation, and despite towing my vehicle in specifically for a 2nd inspection, Audi memphis has stated they have no findings and no liability for the current failure. Given that: • my vehicle is included in the affected range for recall 90s9, • the original repair order appears to document an incomplete or insufficient sealant application, and • Audi's own 90s9 technical bulletin states that damages resulting from improper repair or failure to follow the work instructions are the dealer's responsibility, I am requesting that this case be escalated for review. The current gateway control module repair be repaired at no cost to me. I currently have no working vehicle.

Automatic emergency braking system engaged when the vehicle was parked on an incline. Unable to release automatic emergency brake when vehicle was started with key. Ignition light warning — red — symbol — brake failure. Required a tow to Audi dealership. Audi dealership in two states failed to use omb ii reader to scan codes at the time of emergency visit. Vehicle was released to owner without scanning codes at the time of the emergency therefore owner acquired more than 3-4 consecutive drive cycles before scheduled repair appointment 7 days after emergency incident described above because the Audi dealerships in two states (vehicle occupants were traveling long distance) failed to read and store computer codes immediately after emergency incident with the automatic braking system. This incident made the vehicle inoperable and placed the occupants of the vehicle in an unsafe situation. The failure at the Audi dealerships to retrieve codes at the time of the emergency incident prolonged a permanent repair and will make vehicle evaluation/assessment for safety less reliable given that no evaluation or assessment was done at the time of the emergency at the dealerships and before the vehicle codes were automatically cleared after 3-4 consecutive ‘drive cycles. ’ requested an incline field test with vehicle — place the vehicle in similar conditions— incline — and test automatic emergency braking system— during scheduled appointment 7 days after incident.

Went to mavis on weber rd in bolingbrook, IL for front brake replacement on June 6, 2026. It took 6. 5 hours when I was originally told when I called to schedule the appointment it would only take 1. 5 hours, so it was obvious that something was wrong. Within 100 yards of leaving their parking lot after the service appointment, an obvious clattering was present. I immediately called them to let them know the replacement had not been performed correctly. Booked appointment with Audi of naperville first thing Monday morning to have them fix whatever was wrong - the earliest appointment I could get was June 11. Drove the car until Wednesday evening when something went very wrong and constant clatter was replaced by loud scraping and brake lockup when I exited 355 on my way home from work. Called someone that night to have it towed to Audi for the next day's service appointment. Audi videoed their inspection and shared the video. Their inspection revealed one caliper entirely missing from the driver side brakes and the other caliper on that brake very loose. I paid Audi personally for that repair. I called mavis customer service to notify them of my findings. After pulling the shop video from my brake appointment that day, they got back to me and said they would refund me for that appointment, the tow to Audi, and the Audi repairs. I have since been in touch with them and they said they mailed me a check on July 2. Since it has been 17 days since that date and it doesn't take mail that long to get to most of north America, I tend not to believe them. I have since learned that this mavis brake replacement was negligent and could have resulted in an accident, with the potential of injury. I am contacting you because I don't want mavis to take their responsibilities for the safety of their customers so casually.

The dashboard displayed a solid red brake light with a flashing warning “stop vehicle safely” light. A professional diagnostic scan confirmed a permanent hard fault on the abs control module (j104) and hydraulic unit (n55). The vehicle has only 66,755 miles. Independent repair shops cannot service this unit because it requires highly restricted, specialized Audi factory programming and coding software, forcing consumers to face massive dealership replacement costs for a premature electronic failure ona critical safety system.

On may 21, 2026, at approximately 5:00 pm, my 2025 Audi Q5 (VIN: wa12aagu0s2040827) initiated an unprovoked forward collision warning and emergency braking intervention while I was traveling at approximately 57–58 mph on charlton road in charlton, NY. Road conditions were clear and dry. Weather was sunny. Adaptive cruise control was not activated. I was the sole occupant of the vehicle. A vehicle was making a lawful turn onto the roadway from a t-intersection. There was substantial distance between my vehicle and the turning vehicle. No collision risk existed and no evasive action was required. Despite this, the vehicle's forward collision system overrode my control and initiated emergency braking without cause. As a result of the sudden braking and the force of the seatbelt restraint during the event, I sustained abdominal pain and lower back pain that began immediately following the incident and persisted thereafter. This incident did not occur in isolation. Prior to this event, the vehicle had already exhibited a documented pattern of electronic and driver assistance system malfunctions, including intermittent check engine warnings, repeated false-positive driver assistance alerts, power liftgate malfunctions, sunroof malfunctions, and additional electronic irregularities. All of these concerns were reported to Audi albany prior to the emergency braking event. Following a service visit, I was told nothing further could be done. The vehicle is currently at Audi albany undergoing inspection at the request of Audi of America, including a review of the event data recorder. I am filing this complaint to ensure the incident is part of the federal safety record. A driver assistance system that initiates emergency braking at highway speed without a valid hazard present, on a vehicle with a prior history of false-positive alerts, represents a safety defect that I believe warrants federal documentation and review.

I am submitting this complaint regarding a serious brake-related safety issue involving my Audi vehicle after recent brake service performed by an authorized Audi meadowland dealership in [xxx] . In December 2025, I brought my vehicle to an authorized Audi dealership for replacement of the brake pads. The repair was completed by the dealership, and I trusted that the vehicle was safe to drive afterward. However, only approximately six months later, and after driving only around 1,000 miles since the repair, the vehicle experienced a dangerous brake-related failure involving the brake pad assembly becoming loose/detached while the vehicle was in operation. This incident occurred while my entire family was inside the vehicle, creating a serious safety hazard and placing all occupants at risk. A brake system component should not fail after such a short period of time and limited mileage following dealership service. In addition to the safety concern itself, I am also extremely dissatisfied with the dealership’s handling of the matter. The dealership did not proactively contact me regarding the repair status, and multiple attempts to contact them by phone went unanswered. I believe this issue may involve improper installation, defective parts, insufficient inspection procedures, or other serious safety-related service failures. I respectfully request that NHTSA review and investigate this matter to determine whether similar incidents may affect other vehicles serviced under similar conditions. Thank you in advance for your review on this matter. [xxx] information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Am writing to report a very concerning safety issue with my 2019 Audi Q5 and to request guidance on whether this may be covered under warranty or if my vehicle is experiencing a malfunction. On Saturday, while driving to an appointment, there was a bicyclist in the bike lane. Suddenly, the “Audi presence” warning flashed red on my dashboard and the vehicle braked very hard on its own. I was not close to hitting the bicyclist and there was no imminent collision risk. The sudden braking was extremely frightening and could have caused an accident if a car had been behind me. It took quite a while for me to calm down and get my breathing back to normal after the incident. Then this morning, I received a dashboard warning that said: “drive system: malfunction! please contact service. ” I am very concerned that this may be a malfunction of the automatic emergency braking or driver assistance system, especially after the unexpected hard braking incident. This feels like a serious safety issue. I am very concerned and very unhappy, as this situation felt dangerous and could have resulted in an accident.

Check engine light is on almost constantly on my car. It might turn off and stay that way for a couple of days, but always comes on again. Dealership had made two attempts to "fix" it by just clearing the faults. However, according to the service department the reason why check engine light came on was "faults for loss of communication to powertrain electronics and brake electronics" which I think is a real safety concern. After my last trip to the dealership the check engine light came on after just two days of normal driving. There was also a situation when I was unable to shift to park with the risk of rolling along with some other error messages on the dash. I was unable to lock the vehicle because of that and of course there was a risk of it rolling.

Problem with brake booster servo issue comes on the dash then goes away. Brakes are spongy and brake pedal makes a swooshing sound when pressed.

On December 22nd I got into the vehicle and a few errors popped up which consisted of “loose wheel warning malfunction” “brakes: limited functionality drive with causation” “active front assist and emergency assist unavailable”. I called the nearest dealer and was told it’s ok to drive it’s just a software glitch and if I don’t feel comfortable driving I should take it to the dealer and come back tomorrow for a loaner since service was closed already. So I proceeded to drive home, about 10 minutes into the drive a warning for the coolant came up so I pulled off into a parking lot and as I went to park another warning came up saying coolant too high turn off vehicle and as I was approaching the parking spot the car started to overheat and smoke. This is a brand new car with barely 1000 miles on it.

21 Dec 2025 11,743 miles Audi pre-sense slammed on the brakes while waiting to make a left. Pointing downhill slightly. No cars in the way. Turned it off completely. Was on the the late setting. Will not stay off.

I moved into a parking spot and pushed the brakes to stop but the car accelerated and hit a tree. However when the police drove the car out of the parking spot the brakes were working properly.

On 12/13/25 around 8:00am in the morning. I was driving between 20-25 mph and started to brake for the corner stop sign. I applied the break as I normally would however, the car continued to roll and did not respond to my applying pressure to the brake pedal. No matter how much pressure I apply to the brake the car continued to coast without stopping. I continued to press hard on the break and even pumped the break. After 2 to 3 yards of coasting, the car stopped. I continued to drive the car for another 0. 5 miles and the same break problem occurred again. There are no lights indicating problems on my dashboard. The weather was clear and sunny in the morning. There was no rain. There was no snow. All the roads were dry. I took the car to my dealership and they could not find anything wrong. The brake pads were well within the normal safety range at 8 mm. There was no computer system malfunction. They could not give me an explanation. The Audi dealership’s head mechanic said that because my front brake pads and rotor, and my back brake pads were replaced at pep boys two years ago that this could be a reason for the brake failure. Although he was not 100% sure of this. He suggested that I pay $3500 for Audi to replace the current rotors and brake pads despite the original determination that there were nothing wrong with them. The auto mechanic test drove the car with me after the diagnostic evaluation. He could not detect any problems with the brakes no screeching sounds no noises. The anti brake system was working well. To this day, I still do not feel safe driving this car for fear that the incident with the brake failure will happen again.

This vehicle misrecognizes intersections on two lane highways and causes the vehicle to unexpectedly slam on its brakes without warning in anticipation of an intersection that either does not exist or where my vehicle has the entire right way. This behavior has persisted since the date of purchase and has not been corrected at all. Audi has confirmed that the vehicle is operating as designed however, I have personally almost had two major traffic accidents when this system engaged in the process of overtaking a vehicle, slamming the brakes and almost causing a accident where he and I was rear ended. This is not a vehicle. I would let a child learn how to drive in.

Two weeks after purchase, experienced multiple, random driver assistance failures. After attempting to repair issue once unsuccessfully, the dealership was unable to provide a second service appointment for two and a half months. Was explained all 2025 Audis were having issues, so couldn’t get car in any sooner. Before that second scheduled service appointment and while driving in traffic, the brakes failed.

Audi pre-sense keeps braking prematurely when there is no car present or in its field of view. The SUV brakes without warning and when trying to make a left turn (happened twice already) or while driving on the highway. When the vehicle brakes without warning there is a chance that another vehicle will drive into the rear of my vehicle or I will lose control due to the unexpected and unwarranted braking action. The problem has been reported and documented my my local Audi dealership repair facility Audi silver spring, maryland. The vehicle has been inspected all three times, they have performed a complete 4 wheel alignment and sensor alignment. They have witnessed and documented the code that the SUV reported, Audi pre-sense detected. The dashboard did display Audi pre-sense detected all 3 times when the incident occurred. Audi and I both have the documented repair tickets and they are available upon request. Last incident occurred 1400 on 27 September 2025.

The gateway control module failed in September 2025 on my 2021 Audi Q5. Vehicle error messages included the following failures: cruise control, parking brake, transmission, brakes, and steering, windows rolled down, seats moved, dash and mmi black followed by a sudden loss of power, narrowly avoiding an accident (kids in car). Would not restart. Diagnosis by Audi dealer was that the gateway control module got wet and needed to be replaced. This is recall 90s9 from 2021 that was “repaired” in March 2022 by covering the module with a plastic bag. This proved an insufficient repair backed up by a class action lawsuit filed in January 2022 titled gioffe, et al. V. Volkswagen group of America, inc. , et al. (case no. 1:22-cv-00193). I reached out to Audi USA to request a goodwill repair which was my only available recourse given that the recall had been completed and closed. After 5 days the regional manager denied my request even after I emphasized the safety risk associated with this catastrophic failure as well as the recall in 2021 and class action suit filed in 2022. I paid $1485. 33 to re-repair the recall. Driving home from repair my vehicle alerted me to the following messages: vehicle starting system: malfunction! please contact service, and Audi pre-sense: currently limited. See owner’s manual. An obd scan alerted 7 more codes: 1. Steering assistance id 44 (terminal 30 open circuit), 2. Central electrics id 09 (garage door opener transmitter no communication), 3. Gateway id 19 control module for emergency call module and communication unit no communication, 4. Ethernet notrufmodul keine kommunikation, 5. Ethernet databus branch 1 no communication, 6. Multimedia id sf function restriction due to communication interruption, 7. Driver assistance id a5 dynamic calibration function limitation due to limit value exceedance. I reached out to the dealership that performed the service and was told that those are “ghost codes” and nothing to do with the work performed.

While driving home from the dealership on route 65 at approximately 45 mph, the vehicle suddenly and forcefully applied the brakes without warning. My husband and I are experiencing symptoms of whiplash including back and neck pain. There were no vehicles, pedestrians, or obstacles nearby that would have triggered this response. This was a scary experience, and I am concerned it could happen again in traffic or at higher speeds. This incident presents a serious safety hazard to me, my passengers, and others on the road. The auto was purchased one week ago. Had it in for service. According to the service summary, the driver assist system had a coding error, and a hard reset of the module was performed. Unfortunately, after the braking incident, upon arriving home and restarting the vehicle, the same error message “initializing active front assist” immediately reappeared. I drove the vehicle for an additional five minutes, and the message remained. This suggests the issue was not resolved and may indicate a deeper fault in the system.

My vehicle spontaneously began displaying emergency signals including engine malfunction, turn signal malfunction, parking brake malfunction, brake light malfunction. I would also turn the car completely off and brake lights would remain on asymetrically. Also, the related alert bells would go off intermittently. I have kept my car in good repair and on a regular maintanence schedule. I took the car first to my mechanic who evaluated and said I should take to the Audi dealership. After two days of diagnosis, they came back that the sunroof drains were clogged with debris which definitively caused water to enter and soak the "comfort module" after irrigating them, they did not find any damage and said they do not need replacement. However, the water soaked and heavily corroded the comfort module and say the entire module needs to be replaced along with a rebuild of the harness. They are quoting me $12,300. My safety was at risk in the malfunction of the engine system, and especially signalling capabilities and possible brake impact. The problem has been confirmed by two mechanics - mine and Audi I searched online and have discovered a number of other 2018 Audi Q5 owner accounts of the same and similar defect and result.

I am writing regarding a serious issue with my 2024 Audi Q5, which I purchased brand new and have owned for only 12 months. The vehicle has developed premature rotor wear, which is entirely unexpected given its age, my normal driving habits, and Audi’s reputation for quality. Brake rotors should not require replacement this early unless there is a manufacturing or material defect. This vehicle is still under warranty, and I am requesting that Audi inspect the braking system immediately and cover the cost of any necessary repairs under warranty. Please document the inspection findings and let me know if there is a known issue or technical service bulletin related to this. I am not willing to pay for a component failure that is clearly not due to driver misuse or wear and tear. I expect a prompt resolution and would appreciate a written response confirming next steps. Possible causes (not your fault) defective rotors or materials – if the metal quality was subpar or warped at the factory, they could wear prematurely. Improper factory installation or torque – incorrect installation can cause uneven wear or damage. Caliper or pad malfunction – sticking calipers or bad pads can ruin rotors prematurely. Electronic brake malfunction – Audi’s advanced braking systems (abs, brake hold, etc. ) can malfunction and overuse the brakes.

The vehicle experiences sudden, uncommanded braking on clear roads due to a malfunction in the Audi pre sense system. The system falsely detects obstacles and applies the brakes abruptly, creating a safety hazard for occupants and surrounding traffic. The issue was reported to Audi beverly hills multiple times beginning July 2023, including through the dealer's online service request system. However, the dealer repeatedly failed to document braking concern on repair orders until insistent during latest visit. In one visit (August 7, 2023), the dealer reduced the pre sense sensitivity without creating a repair order or performing diagnostics. At other times, service advisors stated the vehicle was 'operating normally' or refused to record the concern unless it could be duplicated during a short test drive. On August 25, 2025, the dealer finally documented my complaint as 'car would brake randomly' and performed an svm reconfiguration, but the issue persists. The vehicle is currently used rarely for safety.

Reverse car went full throttle, brakes did not work, car stopped in reverse when it hit a tree. Seat belt did not tighten,.

Car was being driven normally within a parking lot of a shopping center. Proceeded to park the vehicle in a parking space. Upon pressing break and holding break pedal pressed, went to push the parking button on gear shifter and car erratically jolted and drove forward and stopped upon impact with barriers/debris/crash. Multiple alerts and warnings illuminated right prior to the incident. Reviews of other drivers of this vehicle reveals similar incidents of unintended acceleration while breaks are actively being applied. No parking button options were stopping vehicle, impact/crash stopped car. Property of shopping plaza/target was damaged, my vehicle, Audi, was damaged and another vehicle parked next to claims their vehicle was involved/hit as well. Safety was critically in danger as breaks did not work and car accelerated on its own without accelerator being pressed rather break was actively engaged and pressing of parking break to shift car from drive to park. Audi pre sense, parking break, tpms and caution symbol alerts displayed. Problems confirmed and reviewed by Audi dealer service. Paperwork is attached along with pictures. Alerts from car has been present for sometime and car has been taken to Audi numerous times with no action by dealer, car is new and is a lease. Audi is aware of these issues had took no action to Audit/fix cars systems. Shortly after those visits to dealers this incident occurred. Believe these control modules having a correlation with cars sporadic behavior. Audi service documents: story: 5354 TSB 2070571/2 duplicated customer concern during the initial test drive. Ran gff with diag id 186214649 found dtc p060c00: internal control module main processor performance. Found TSB 2070571/2. As per TSB "1 clear the dtc p060c00 and return the vehicle to the customer. 2. Explain to the customer that a solution is expected to be available by the end of the 1st quarter of 2024 (subject to change) and that no repairs are necessary at this point.

The Audi "pre sense" automatic braking system engaged without warning and without reason bringing the vehicle to a sudden and complete stop in the middle of an intersection and slamming my body backwards and causing my head to go forward nearly hitting the steering wheel. A school bus was directly behind me and was able to stop in time before it ran into the back of my vehicle, but it could have caused serious injury or death to multiple people. It caused a considerable amount of pain in my neck the day after and soreness in my ribs. The vehicle gave no prior warning. It did display a message simultaneously when it applied the brakes and locked the seatbelts that the "pre sense" had been engaged. It has happened three times prior to this incident. The vehicle dealer has told me that they see record of the system engaging but it does not appear to be faulty by the manufacturers standards despite numerous complaints and frequent occurrences.

We were driving today at around 11:30am and all of a sudden the “Audi presense” light came on at the same time the car brakes abruptly slowed down the car for about 5 seconds or so and then released. Today is a beautiful sunny day and there were no vehicles anywhere or anything in roadway on the road we were traveling on. The jerking /abrupt slowdown really surprised us. We will go to Audi dealer ASAP but now we don’t trust when it will happen again. A car could have hit us from behind.

I was pulling into a parking space at approximately 5 mph and the car unintentionally accelerated causing me to jump the curb, go over a grass median and land perpendicularly onto a one-way active road. There were trees and other items on the median I could've hit had I'd been pulling into a different parking space. I also could've hit cars on the road. I quickly got off the road and parked the car.

Comfort control module (j393) is malfunctioning due to water getting into the wiring components and surrounding areas. The rear lighting stops working all together; no taillights, no brake lights, no turn signals, no license plate lights, and no lights when backing up. The problem has been reproduced by an authorized dealer. The component was removed by the dealer and noted of water inside the module and corrosion on the pins/ internals because of the water. The warning lamps occurred at the same time the lights stopped working. There was never any "prior to" warning. The warnings disappear randomly, no set time until they cleared. I am assuming once the module dries out over time is when the warnings start to clear but that is just speculation. Unknown cause of the incident, but water is getting into the inside of the car somehow.

Recently on a number of occassions the car stopped because the pre-sense sensor went off prematurely. There were no cars within 500 feet of my car on all occassions. Now the pre-sense has completely turned off and will not turn back on.

My wife and I were in the 2023 Audi Q5 with 1000 miles. I had complained to the dealer and manufacturer that this car was unsafe to drive. On June 9, 2023 I was driving slowly in my community. I tried to stop at a stop sign. No brakes then at the same time the car had unintended sudden acceleration. We had no control, no brakes and hit a fence and shrubbery and cement fence. All airbags deployed.

The sunroof draining is designed in such a way that if the holes get clogged, the water can back up and flood the comfort control module in the rear of the car rendering it useless. That module controls critical parts of the driving of the car like turn signals, the on/off starter motor, which if they fail while on the road make it incredibly dangerous to drive. Audi has already recalled the car to "enclose" the gateway control module but refuses to take responsibility for damage to the comfort control module caused by badly designed sunroof drainage. This incident caused a $9,000 repair that they refused to pay for.
