Service Brakes Problems of Audi Q5 - part 1

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.

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.

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.

The contact owns a 2023 Audi q3. The contact stated that while driving approximately 5 mph over a speed pump the driver pressed the brake pedal while approaching a stop sign when suddenly the vehicle accelerated forward at a high rate of speed and crashed into a fence and brick wall. During the crash the driver sustained a fractured nose, head and face lacerations, neck and lumbar pains and a right arm laceration which required stitches. The front passenger sustained neck, lumbar and chest injuries. Both occupants required immediate medical treatment. A police report was taken at the scene and the vehicle was towed away and later listed as destroyed by the insurance company. The cause of the failure was not determined. The manufacturer and local dealer was notified of the failure. The failure mileage was 1030.

Complete hydraulic brake failure while on an interstate going 75mph. No warning, just sudden loss of regular and emergency brakes. I was able to cross 4 lanes of traffic to get to the shoulder where I waited absolutely terrified of being rear-ended for the two hours it took for a tow truck to arrive. My repair place was shocked at the problem, considering the car was 8 years old with low mileage. They found the only after-market part in the entire country and repaired it for under $2000 when they initially thought it would be $6000.

The contact owns a 2022 Audi Q5. The contact stated while driving 65 mph, the brake failure warning light illuminated. Additionally, the doors locked independently, and the windows independently rolled down. The contact attempted to depress the brake pedal; however, the brake pedal was extremely firm. The contact was able to stop the vehicle on the side of the road and turned off the vehicle. The contact waited for the vehicle to cool down before restarting the vehicle. The vehicle was taken to the dealer to be diagnosed; however, the dealer found no failure with the vehicle. The manufacturer was contacted and referred the contact to the NHTSA hotline for assistance. The failure mileage was 5,000.

In short my front right brake caliper failed. To be clear, brake fluid seeped out of the main 2 halves of the caliper. After some investigation there appears to be a recall on this issue on 2017 models and newer but not on my 2016. Per my mechanic this failure is rare and unusual and could have been catastrophic. The brake light warning did come on, but the amount of fluid that seeped was significant in that even 1 day after my light came on and driving a short distance to the shop, almost all of my brake fluid had seeped out.

Accident occurred in the parking lot as I was trying to park, sudden unintended acceleration occurred that caused the car to hit the building. Neither front nor back airbags deployed, as well as the automatic emergency break of the collision safety system did not work or activated to stop the car. Both my wife and I were hospitalized. The auto emergency system of the Audi Q5 is not reliable, and the need for recall.

I was trying to park my car in my office parking space, after right turn to parking space, I applied brake to stop, but the car suddenly accelerated and within few seconds it crashed into the office building. I was still applying brake when it accelerated and I could not do anything else. The fact that vehicle climbed two levels of curbs to hit the building shows that the acceleration was out of my control. And even vehicle's collision system did not kick in when car was climbed over the curb. Polic report #: 22-350-0239c agency: sccso.

Two issues: 1. We have needed to repeatedly replace brake booster. 2. Passenger side rear spring has broken and dealer is indicating the driver side should also be replaced.

A 2022 Audi Q5 phev abruptly stopped and displayed three warning lights on the dashboard (electrical system malfunction, drive system malfunction, and check engine light). Car was unable to move. Had the car abruptly stopped on a highway, a serious accident may have occurred. There were no prior warnings. After restarting the car several times, the malfunction messages disappeared and the check engine light stayed on. The driver drove it less than 5 miles to the dealership after contacting the dealership to provide advance notice of the car’s arrival. On the same day, the dealership said that the check engine light cleared itself and they did not find any codes to diagnose an issue. Without a diagnosis, the dealership cannot state that a similar incident would not occur in the future. After four more days with the car, the dealership maintained that there were no codes to use for a diagnosis (reported only sporadic codes and not hard codes were found) and the car was ready for pickup. The driver will request an inspection by another Audi dealership service center. The driver has also experienced an intermittent hard brake pedal issue with this model. Issue noted at dealership in August, but not replicated and the issue still occurs infrequently.

While driving at a relatively low speed, approximately 30 mph, I approached a red light and proceeded to slow down. The brakes did not engage, so I continue to pump them but had to swerve into the right lane to avoid hitting the car in front of me. Fortunately, there wasn’t a car in the right lane. It was raining but not heavily, although earlier we did go through heavy rain on the freeway. After this incident we still had to drive about 5 more miles to get to our destination. The brakes worked the rest of the way. I took the car to Audi to have them check it and they said they didn’t find anything; however, this was certainly some sort of brake malfunction.

Incident happened on 4/24/2022 ~ 10:00 am. Stopped at a red traffic light. An error message 'brake malfunction' showed up on the dashboard screen. After traffic light turned green, vehicle was unresponsive when gas peddle was pressed. After the engine was restarted twice, vehicle started to move but engine light was on.

I've reported multiple times to my dealer about the oil comsumption back in 2022 and work was performed on the vehicle in the prior year to fix leak and brake noise issue since approx 2021 on my 2015 Q5 that currently only has 65,000 miles. No warning indicator presents regarding the brakes. However oil indicator and engine light icons display. I'm constantly checking the oil indicator level to see how much is still in the and then add add once it shows thats its extremly low. I have to do this everytime I am about to use the car. This can be dangerous at times since there's no indication that its very low and its not seen unless you go into the "car" section that shows the level, it has no alert display for the level. All required diagnostic and maintenance services have been performed with the dealer. When inspecting the brake issue they always come back with no findings say that no issue could be found, howeve when I'm driving it, it sqeeks and makes a grinding sound all the time. This has been going on for quite a few years. As for the oil consumption issue, this isssue has been in recent years and both times this has been looked into by the dealer I was informed that its not covered under any manufacturers warranty and would cost me approx. $10,000. 00 for them to repair it or I could trade it in. This is a very expensive luxury car and at this low milage shouldn't have these types of issue. I've seen on various car sites that both the oil comsumption and piston issue is a known issue with this model Audi and that issue occurs aournd 60,000 miles but was rectified for the models that came after 2015. I wish I had know this before making this purchase. Now the driver seat adjusting panel is broken, this came out of no where about four weeks ago with no warning. I haven't received any recall notifications since my Audi care coverage expired, not sure why this would stop because I didn't continue this service.

After driving on deep wet icy slush, the vehicle was on a straight section of road and suddenly vehicle inexplicably veered hard to the left causing it to run off the road and into a tree. Electrical component failure lights were illuminated on dash afterwards. What component or system failed or malfunctioned, and is it available for inspection upon request? I believe that the stability control systems and or drive train suddenly changed. I believe this might be due to water ingress and failure of gateway module. This is available upon request. Car is in shop how was your safety or the safety of others put at risk? sudden loss of steering control in icy conditions has the problem been reproduced or confirmed by a dealer or independent service center? not yet. Current recall has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? body shop is looking at vehicle were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? I was unaware of warning lamps until after loss of control.

I received a safety recall from Audi of America for my 2019 Audi Q5, I am pleased that the recall is being done. However, the description of what could happen, in the safety recall letter, should water enter the gateway module does not describe what happen to me when the gateway control module got wet from liquid spilled in the backseat of my car. The 2nd paragraph under “ what is the issue “ states in part, “ the vehicle remains steerable and the brake system is fully operable. The engine goes into emergency mode and remains in operation with reduced power. “ I was driving my 2019 Audi Q5 on December 12, 2021 on a heavy traveled avenue with many traffic lights. As I went thru the second light before entering 1- 20 west the car just shut down and I mean totally stopped. No warning, nothing. The vehicle was not steerable, the brake system did not work the engine did not start, did not go into an emergency mode and did not remain in operation with reduced power. The car was totally un-operable we called 911 for the police and a tow truck. We sat in horrible traffic for more than 2 hours even with the police. And the car could not be towed with a regular truck because the wheels were locked. Thus another tow truck had to be called so the car could be put on a flatbed truck to be taken to the Audi dealer. I believe the safety notice from Audi needs to be corrected to give notice that the gateway control module when exposed to water can and has shut the entire system down and the car can become entirely inoperable as I described above. This is a very dangerous situation which may not only cause serious accidents but permanent injuries and death. I shiver now when I think of what else could have happened to us, but for the grace of god, because we were seconds from getting on I- 20 west when the car just stopped. I appreciate this opportunity to share this information with you. I hope it will make a positive difference for the safety of others.

1. When parked on a slight incline, vehicle rolls forward (downhill) after shifting from park to reverse. Dealership says this is normal, says car will roll forward up to 10 feel even when transmission is in reverse. Appears to be due to a design defect in the electronic transmission. 2. Windows will not open when outside temps are below 20 degrees. Dealership says they have no solution. This car has a bunch of other problems that Audi won’t address, but the above are clear safety issues. Thank you.

I was driving down a slight hill in 1/2 inch of snow at 5mph and when I tired to gently brake as I descended the hill, the brake pedal had no resistance and went flat to the floor. I had no brakes. I then tried to steer towards the side of the road and the steering wheel completely locked up and I was not able to steer. I slid 150 feet down the hill and into a ditch. No brakes and no steering. There must have been a failure of some kind. Terrifying.

Gateway control modular failure. At dealer currently. We took pictures. Multiple reports of the exact same thing on Audi forums online. Audi confirmed same issue. While driving car it suddenly stopped and the emergency brake was automatically applied. No warning, no way to live the car to safety, all the warning lights began to flash, windows started to rolling up and down. Then the car just turned off. Unable to start it, turn it on, move it, nothing. Needed a special tow truck to have it towed to dealer. A serious safety issue. I am 8 m pregnant, had my brother and 4 year old nephew in car. I am concerned for my safety but equally concerned for every Q5 has this gateway module in this location. Every person driving a Q5 and other drivers can be affected by the design flaw of the location/ lack of protection of this gateway module. We were lucky we were not on the highway. What if this happened on a highway at high speeds or in a curve.

The 2nd generation Audi Q5 (roughly 2017-2021+) has a major susceptibility to immediate, catastrophic failure as evidenced from my own experience and dozens of episodes reported online. This failure typically causes a $2000-$3000 repair bill that Audi will not cover and will claim is the fault of the owner. My wife was driving the vehicle with our 5-year-old daughter in the car in the middle of the rear seat. The daughter spilled part of a 500 ml water bottle onto the seat next to her. Within 20 seconds of this happening, the car began alerting about steering malfunctions, braking malfunctions, and the windows began seizing up and down repeatedly. The car was completely inoperable. We are lucky this was on a slow city street and not on the interstate or tollway! once stopped, we no buttons generated any actions from the vehicle. We couldn't power it on, put it into neutral to be towed away, raise the windows, or perform any other function at all. The car was a useless brick. We were charged $125 for the towing service and another $2200 from Audi plano in texas. After countless conversations, even debates, with david (director Audi plano) and even Audi USA customer experience team, they refused to admit any fault in a poor design and help cover any of the costs whatsoever, and we are even still in warranty. .

When pressing the brake pedal at times you hear a metal clang sound like something hitting a tin can. This happens often but is not consistent. I have video evidence of this as well as have seen this item discussed in detail of Audi forums. Audi claims regardless of my evidence nothing can be done. My concern is it has to do something with the brake and to me is a saftey concern.

2017 and newer Audi vehicles with rear cross traffic alert and possibly those with just Audi pre-sense are extremely frequently generating false positives when reversing. The system is incorrectly sensing an object and activating the parking brake to avoid a collision. This results in a sudden vehicle jerk, brakes scraping, and immediate confusion for the driver. I have personally experienced this on numerous occasions when reversing and have attached dozens of complaints showing this is a widespread fault in the design of the system. It is falsely activating because it is not accurately tuned to detect an incoming object. . Read more...

I approach a city intersection at the fort lauderdale airport and had no brakes, steering, or accelerator control. The vehicle was completely unresponsive. I flew through the inspection hitting the curb and launching my vehicle approximately 50� of distance over a drainage ditch slamming to a complete stop on the other side. The speed was at least 40-50mph at that moment, maybe faster since the vehicle just accelerated but would not brake or steer. I had my seatbelt fastened and airbags were deployed. The vehicle was totaled and the frame literally shattered on impact. I sustained serious trauma to my face and back and ankles.

Audi pre-sense braking fault; recall needed! 1- while moving forward on an empty, flat, 2-lane, suburban road at approximately 35mph, the brakes suddenly activated, bring my vehicle to a near stop, with a loud, grinding sound. Terrifying. There were no objects or vehicles on the road, no glaring sunlight or other problems that could have caused this. April 15, 2020. 2- twice or more, in the few weeks or so prior to this event, while backing up into my garage, the vehicle suddenly stopped with a loud grinding sound. There were no objects, vehicles, glaring lights, or anything that would have caused the vehicle to brake this time vs. The hundreds of other times the same process had been completed. Between January 1, 2020, to present. Vehicle was approximately 1. 5 years old and approximately 10,000 miles when these braking events happened. I believe the problem is caused by an error in the Audi pre-sense system, which causes the vehicle to brake to prevent a collision.

Overall problem: Audi Q5 2020 appears to have a computer malfunction that instantly disables all systems. Vehicle �shut itself off� at a brief stop and became very difficult to control, rolling into intersection. Details: I stopped car at residential neighborhood stop sign (brief and complete stop, no wait), immediately ready to proceed forward. Audi's �auto stop/start� feature shut off the engine, then immediately all electronics shut down. The car basically �turned itself off. � vehicle then began drifting/coasting into intersection. Controls were unresponsive. I realized the power brakes and power steering were disabled. I braked very hard, which stopped the car. Had to keep brakes pressed very hard to keep car from moving. Ignition button was unresponsive. I then noticed a small message on the dashboard controls which read something like �start/stop ignition system disabled � put car in p. � (this was the only working electrical feature I noticed, the event was frightening and disorienting, but I'm fairly sure nothing else was functioning). I then shifted gearshift to park, and was able to start the car and drive away. I reported problem to dealer. Dealer claimed to inspect vehicle, and said they were unable to find anything wrong. Dealer said vehicle's computer had no record/memory of the incident. Dealer also seemed resistant to properly documenting the incident on their paperwork. I reported the problem to Audi corporate in auburn hills mi, explaining I no longer felt safe driving this car, and would not drive it again. Audi claimed to perform their own investigation, and their brief reply said that they were not obligated to do anything under applicable lemon laws. Car was in 3rd month of lease, ~150 miles. Previously I drove an Audi a4 2017 for 3 years so I was/am very familiar with the way Audis operate.
