2021 Audi Q5 Owner Complaints

I was driving at highway speeds when a "Transmission Malfunction" warning appeared, and the vehicle lost the ability to accelerate. Once I was able to pull over and put the vehicle in Park, it completely lost the ability to engage Drive or Reverse, leaving me stranded. Important to note pulling over was difficult as I was on a highway driving ar 70mph speed and trying to locate safe space to stop avoid collusion. My car towed to the nearest dealership for repairs. Audi dealership confirmed the cause was broken internal transmission filter housing bolts. I was told this was premature occurrence as the vehicle only has 35,760 miles of driving and no prior work done on the transmission or visible notice of damage that could cause this issue.

If I have a sensor that will malfunction due to water then there should be a water indicator alert. My sunroof vent was blocked and water went into my trunk where the core module is. I had just come to a red light to turn on to a major highway and my car began to smell like fuel. I rolled down the windows and realized the smell was not as strong as inside. The light turned green and as I stepped on the gas the car went into limp mode as I was in the middle of my turn. The power steering then went out in the turn and the wheel yanked to the left and put me half way into the lane next to me. Thankfully no one was there. I had to yank it back to the right to get off of the highway on to the side of the road. I do not think that the power steering should be associated with that module or at least a water indicator sensor should be added. What happens if someone is on the interstate is driving 75 mph and their power steering goes out. It's in the shop and there is no damage other than now I am scared to drive it

I was driving down a regular road by my house, full sunshine, perfect road, nothing unusual. In fact, it was such a nice day, the sunroof was open and windows were down. My dog was in the back seat after just being picked up from grooming happily enjoying the day with his head out the window. I was on a road with the speed limit of 30. I was going 30 mph. Nothing unusual. Literally, out of nowhere, like my car was possessed, is the best way I put it, my car abruptly braked in an attempt to stop on a dime. My car screeched to a stop while simultaneously my windows rolled up, my sunroof closed and my seat belt tightened, locking me in place. My dog was thrown forward. It was terrifying! Luckily, no one was behind me or they would have certainly rear-ended me. Nothing was in the road. Absolutely nothing. It happened so quickly in a split second. I put my hazards on and finished the next 2 miles home. I called Audi for a service appointment. I took my car in, again going down back roads with my hazards on. Audi charged me $400 to run a diagnostic report and shows there is a fault code J428. This fault code I researched is for the front/right ACC radar sensor that powers Adaptative Cruise control and Pre-Sense braking system. The fault code erroneously detected an obstacle and did abrupt braking. Audi told me that they would charge me $4,000 to fix it. I contested that as a safety issue it should be fixed as there is also Audi TSB2063502 referencing problems. This is a major safety issue as if I was going 70 MPH, I could cause a massive accident where I could be killed, anyone in my car, as well as others behind me in a massive car pile up. I feel ethically, this must be a safety recall to replace this fault in all vehicles. I am also requesting payment to fix from Audi. As an attorney (#[XXX]), Audi is under notice that they have a major safety defect on their hands and should take steps to protect drivers safety. Thank you.

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)

The safety situation happened when my wife's car got stuck while driving at about 25-30 MPH in the middle of the road.Next day At the nearest Audi service center they found that water has gotten into the rear of the trunk and damaged the electronic module which caused the car to stall.The first repair was estimate at 4600 $ .After the repair the car was inoperable.The next repair was estimated at another 4 700 $.After the second repair the car was inoperable again and the service department told me that the car needed to replace the entire transmission .Which they estimated at another 20 000 $. So the total damage is around 30 000$ .I contacted Audi USA about the whole situation when I received a negative message regarding the solution . I would like to point out that up until the moment mentioned we had no problems with the car .After my personal investigation of the problem ,I found that there was a safety recall # 21V-947 for same problem .It was not issued for my car which meets all the criteria.It looks like it was hidden by the manufacturer. Audi distances itself from the whole problem and refuses to cover the costs of the damage.Thank good this happened on the city road where the speed is low .If this happened on the highway at 60 MPH it would have had tragic consequences .Where it would never have been figured out what caused the accident. From a safety perspective ,I m reporting this dangerous and unfair treatment of customers by AUDI USA regarding the hidden recall and denial of resposability that occurred and I request an investigation .

Following a rear collision repair at an authorized dealer collision center, multiple ADAS safety systems were not properly calibrated despite insurance payment and shop representations that repairs were complete. WHAT FAILED: Lane Change Assist, Peripheral Camera System, Side Assist, 360-Degree Camera, Front Camera, and Adaptive Cruise Control were either not calibrated or calibrated in timeframes physically incompatible with manufacturer specifications. SAFETY RISK: Driver relies on blind spot monitoring and lane change alerts that may be non-functional or inaccurate. Without proper calibration, these systems may fail to detect adjacent vehicles, provide false alerts, or create blind spots in camera coverage, increasing collision risk during lane changes and merging. DEALER CONFIRMATION: Yes. Shop manager provided diagnostic logs as proof of calibration. Analysis shows 360-degree camera calibration executed in 18 seconds versus 40-60 minute industry standard, and zero calibration events logged for Lane Change Assist and Peripheral Camera systems explicitly claimed as completed. INSURANCE INSPECTION: Insurance company explicitly DENIED Lane Change Assist and Peripheral Camera calibrations on estimate. Shop admitted in writing these items were declined and blamed insurance for non-payment. No OEM calibration logs produced despite multiple written requests. WARNING SYMPTOMS: Systems may appear normal on diagnostic scan with no active fault codes, but this does not prove calibration was performed to OEM tolerances. Physical calibration requires target board positioning, laser alignment, and environmental verification that cannot be completed in documented timeframes. PATTERN CONCERN: This may represent a systemic issue where insurers deny ADAS calibrations, shops skip calibrations due to non-payment, vehicles are released as complete, and consumers unknowingly operate vehicles with compromised safety systems. Vehicle and documentation available for inspection.

Vehicle: 2021 Audi Q5 I am submitting this complaint regarding a serious safety defect involving unintended emergency braking. On September 10, 2025 and again on January 8, 2026, my vehicle suddenly applied emergency braking while I was driving and there were no vehicles, pedestrians, or obstacles in front of me. The dashboard displayed “Auto Pre Sense” during both incidents. These unexpected braking events created a high risk of a rear-end collision and placed me and other drivers in immediate danger. This is not a driver error, but a malfunction of the safety system. Because this has occurred more than once, I am concerned that the Audi Pre Sense system in my vehicle may operate unpredictably and cause a serious accident. I respectfully request that this issue be investigated as a potential safety defect.

While driving my 2021 Audi Q5, the vehicle experienced a sudden transmission disengagement without warning. The vehicle behaved as if it had shifted into neutral while in motion. When this occurred, pressing the accelerator produced no response — the engine would not rev and the vehicle would not accelerate. This created a serious safety risk as it occurred during normal driving conditions and could have resulted in a collision. After stopping the vehicle and shifting into Park and then back into Drive, the transmission temporarily re-engaged. The issue reoccurred multiple times. Prior to one of the failures, the vehicle hesitated and bucked when starting from a stop. A warning message later appeared stating: “Transmission malfunction. You may continue to drive but will be unable to reverse.” The vehicle was taken to an authorized Audi dealership. Audi of America approved replacement of the transmission control module (mechatronic unit); however, this repair did not resolve the problem. After repeated failed adaptations and diagnostics, the dealer confirmed that the entire transmission requires replacement, citing internal gear set failure. The dealer documented that: Basic transmission settings and adaptations were attempted at least five times The failure consistently occurs at the same gear position A similar Audi Q5 case required full transmission replacement Audi Technical Assistance Center instructed the dealer to replace the transmission Despite this, Audi of America has refused further assistance due to the vehicle being slightly outside the standard warranty period, even though the mileage is extremely low and the failure is safety-related. This appears to be a defect involving the Audi S-tronic transmission, as similar complaints have been reported by other owners. The sudden loss of propulsion while driving presents a clear safety hazard. Safety Impact Sudden loss of acceleration while driving No throttle response during failure Occurred wit

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.

On September 18, 2025, while driving at ~65–70 mph on the Saw Mill Parkway in Mount Kisco, NY, a Michelin Latitude Tour HP tire (235/55R19) suffered a sudden circumferential tread/belt separation. The tread detached completely from the casing while the sidewall remained intact. A small screw was present in the center tread, but there was no TPMS warning or gradual pressure loss prior to the failure. This behavior is inconsistent with ordinary puncture damage and indicates a potential workmanship/materials defect. The separated tread, tire carcass, and wheel are preserved and available for inspection. The tires were installed by the dealer (Audi New Rochelle) on June 12, 2024, as part of Certified Pre-Owned reconditioning before sale. This catastrophic failure posed an immediate risk of serious crash. Tire Size: 235/55R19

My car always did a weird shuddering thing when taking turns a certain way. I just thought it was part of how the new vehicle worked. I thought it was strange when I took my car in to repair a front tire, and was told / showed that the back two tire treads were worn down. The new car only had 20,249 miles. But I read somewhere that some new car dealers use lower tread tires to save money, so I did not pursue anything. Then, when someone pointed out that the 'weird shuddering' was not normal, I took it into Audi to have them look at it. Audi did a repair, and said I had to drive it 600 miles to know if it would be resolved. After the 600 miles, the problem continued. I took back, and they said they know what it is but they have to go through certain steps first. They told me this time that the good news was that they would replace with a new center differential, but the bad news was they were not sure how long it would take to get one in. I waited patiently, and then received a call saying it was fixed, (but they did not replace the part). What I did not know at the time was that a message was left 10 minutes earlier saying the part came in and they would be replacing it. After further questioning, the Audi guy said the new 'fix' heats up the fluid better and allows it to work its way through better. He said he was informed moments after he left the VM (where he said they were going to replace it), that the technician told him, and he took it for a drive, and it was 'fixed.' He then told me what he drives, saying his does it too. He said the technical bulletin says i must drive 250 miles (again) and later when I picked it up he said 500 miles. I pointed out my concerns regarding the safety of driving a malfunctioning differential (loss of traction, poor handling, and the potential for complete failure while driving), as well as uneven tire wear. He emphasized that it's fixed and completely safe, even though they did not replace like I was told they would.

While driving on the highway (70mph) at night, my instrument panel went completely dark. I was not able to see the speed I was driving and my warning sounds/lights were not working. The dealer could not get me an appointment for 4 weeks so I took it to a mechanic who specializes in European cars. The diagnostics indicated a loss of power to the instrument cluster/panel. I was told there was an active recall for this issue, but my VIN was not included. As this is a safety issue that sounds very familiar to the current recall for other Audi models, I contacted Audi and after inspection they diagnosed it as a failing instrument cluster. Since it's not in the current recall, I'm having to replace it. I've had computer issues in the past which the current Audi dealership has checked and told me there was nothing wrong, but after speaking to the Audi service tech many of the recalled issues were solved by a software update. The loss of the instrument panel is a major safety issue and Audi refuses to resolve the issue.

The small buttons that are part of climate control on the dashboard pop out and fall off. The pieces aren’t supposed to do that. They are actually designed to work as buttons that stay in place but whatever mechanism that is designed to keep them is place comes off. I have tried just putting the buttons back in but they will eventually pop off again. My car is relatively new and should not have buttons popping off. No car of any age should have buttons just falling off. These are small buttons that pop off at any moment if there is a defect and I think could be a potential choking hazard for children and pets. If one falls off and I don’t notice and is just rolling around on the ground, it could be an issue with pets especially. My buttons fell off in the middle of the night and I had to search the vehicle for it. This is also the control system for the fan in the car. In extreme climate, if this falls off, there are no means for controlling the climate of the vehicle. Yes, the problem has been reviewed and confirmed by an Audi Dealership. The only solution seems to be to order a brand new dashboard and climate control system but it’s the same system and can’t guarantee that the buttons won’t pop off on the new ones. There are no warning lamps, messages, or other symptoms prior to failure. The buttons will randomly pop off sometimes with no one in the vehicle or in the middle of just driving somewhere. They will just pop out. Several people are having this issue but Audi refuses to address the problem and instead forces everyone to by a brand new climate control system with the same faulty button system.

Virtual dashboard where speedometer and safety warning are displayed has stopped working. Display has completely shut down. I cannot see any critical information to drive vehicle. I contacted the dealership to address a serious safety concern that mirrors an issue already under active recall for other models by the manufacturer. Despite this, the dealership has refused to perform any inspection or repairs, stating that my specific model is not currently included in the recall—even though the symptoms and risks are identical. This refusal raises significant concerns, as it leaves a known safety issue unaddressed solely due to recall limitations that may not yet reflect the full scope of the problem. In order to receive any resolution, the dealership is asking to cover diagnostic and service costs for the safety issue.

The instrument panel cluster assembly (screen behind steering wheel) needed to be replaced because it would intermittently stop working and I had no idea of how fast I was going, what gear I was in, how much fuel I had or whether the lane assist and other safety features were working. Without knowing speed, I may have followed cars too closely to safely stop or I could have run out of gas and left stranded somewhere. I thought it might have been software updates occurring but after a few days, I went to the dealer for service. Audi Naples was able to detect fault, replicate problem and replaced the assembly on 4/10/2025 for $3,391.96. The dealer kept the part and told me to keep my receipt in case there is a recall. My car currently has 31,489 miles and had a total inspection and was last serviced on 1/22/2025 with 31,487 miles. I find it outrageous that a part like that would fail in such a short period of time. I was lucky I wasn't on a long trip away from home when it occurred.
