NHTSA complaint #11757818 — an unverified report by a vehicle owner.
Our '22 Audi Q5 experienced a spontaneous sunroof implosion while driving on the highway. Temperature would not have been a considering factor here, nor did anything hit the sunroof but it exploded and showered the occupants with glass - both pebble-sized pieces and small shards. The curtain was open at the time and glass went everywhere. Thankfully, the driver had the good sense to pull over immediately without an accident. This incident interrupted their trip, they had to find someone to tape a plastic cover over the gaping hole, then have the sunroof replaced, all at considerable expense and hassle. This was both a very dangerous AND frightening experience. Audi headquarters was contacted and denied any responsibility, saying that we need to handle this through our insurance company which I find outrageous as it has been recorded that quite a few Audis have experienced this same situation. It should be covered under their warranty!!

There is considerable rust to the point that the subframe has been structurally compromised. I also contacted Audi USA regarding this issue, but they advised that they could not provide any assistance and closed my case. I was instructed to have the vehicle inspected and see what the dealer could do. I have videos and photos documenting the compromised subframe which many Audi Q5 owners have been complaining about.... There are holes approximately the size of a tennis ball.
NHTSA complaint #11739161 — an unverified report by a vehicle owner.
2019 Audi q5 drive system malfunction/start stop malfunction. Error code will come on randomly in traffic and when you try to put your foot on the gas it hesitates and you need to push harder on the gas. Car will also lose acceleration power and take longer to reach desired speed. Drive system malfunction light will come on as well as an error stating start/stop system malfunction. Have had multiple sensors and battery replaced with only temporary results. Start stop malfunction will come on randomly at any time and then go away for a certain amount of time and come back again. This malfunction is constantly going on and off and is sometimes dangerous because you don’t know when it will happen, if it does happen you don’t know if you need to press harder on the gas, or if you do accelerate you don’t know if you’re damaging your engine. After multiple fixes at Audi dealership and other repair shops, them attempting to address this issue has done nothing for the car leaving me to believe this could be a fault. This issue has been going on for at least 10 months with multiple dealer visits attempting to address this issue.
NHTSA complaint #11737448 — an unverified report by a vehicle owner.
My seat belt warning has been going off intermittently. I received an extended warranty from Audi Subject: Seat Occupancy Detection System Limited Warranty Extension extending the warranty for my car. However, when I took it to the dealer they could not replicate the sound. I provided them a video of it happening. They said it was not showing as a fault on the computer and therefore refused to repair the seat under the warranty extension. This is a safety issue and it's recognized as one by Audi. This sensor is obviously malfunctioning for a lot of people or they would not have extended the warranty. Regardless of being able to "replicate" the issue, they should replace the sensor since it's a known issue and they extended the warranty on it.

My dashboard VIN plate was destroyed when the windshield was being replaced. I’ve been trying to get Audi to send me a new VIN since October 23, almost 6 months ago. They assigned an executive case manager 2 months ago but that’s accomplished nothing. The vehicle is out of compliance with federal law without a VIN plate and I cannot trade or sale the car. Please help me.
NHTSA complaint #11731416 — an unverified report by a vehicle owner.
Component/System: Engine. The vehicle was destroyed by fire but the remains are available for inspection depending on insurance/salvage status. Safety risk: Around [XXX] on [XXX], my 2023 Audi Q5 began smoking as I was exiting the vehicle with my [XXX] daughter and then caught fire and was completely destroyed. This created an immediate risk of serious injury or death to me and my child. I live across from a park and there were many children and families nearby who were at risk as well. Dealer/service confirmation: I just learned of recall 15ZK (loose cylinder head cover screws/oil leak fire risk) after the fire. I never received a recall notice despite owning an affected vehicle. Inspections: The incident was responded to by Silver Spring/MCFRS Fire Station 19 along with local police on April 12. The vehicle has not yet been inspected by my insurance company. They are expected to send an inspector on April 13. Prior warning symptoms: I recently noticed a fuel/burning smell originating from the front of the vehicle. The smell was detectable from outside the car after driving but was not present inside the cabin. No warning lights appeared on the dashboard. The smell persisted for several days prior to the fire without resolving, consistent with the oil leak described in recall 15ZK.

NHTSA complaint #11721962 — an unverified report by a vehicle owner.
I am submitting this complaint to report a safety defect involving a 2018 Audi Q5 (Premium Plus, Technology Package). The vehicle’s MMI infotainment/navigation system intermittently shuts down or reboots during operation. When this occurs while the vehicle is in in reverse, the rearview camera display immediately goes blank and remains unavailable until the system completes its reboot cycle. This failure has occurred during active reversing maneuvers, creating a significant safety concern. An incident already occurred that resulted in an impact to another object during backing and the camera display/MMI going blank loss just prior to stopping. The rearview camera is a required safety system under Federal Motor Vehicle Safety Standard No. 111. When the system powers off unexpectedly, the driver loses critical rear visibility information at precisely the moment it is most needed. The condition appears to be software-related, as the infotainment system restarts on its own. However, the temporary loss of the camera display increases the risk of collision with pedestrians, other vehicles, or stationary objects. I understand that recalls have been issued for similar rearview camera display failures in later model-year Audi Q5 vehicles. The symptoms I am experiencing are materially similar and may indicate a broader defect pattern affecting earlier production years. I have attempted to resolve the issue with Audi and their technicians and service management. The conclusion was they could not find any error messages or mechanical issues. They would not diagnose deeper or complete any further trouble shooting. The previous owner also attempted to resolve the safety defect under warranty and received similar attention with no solution. I respectfully request that NHTSA review this matter for potential investigation to determine whether the 2018 Audi Q5 should be included in any safety-related corrective action. Of note, the "CarPlay" use is not the cause.

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 .
NHTSA complaint #11718005 — an unverified report by a vehicle owner.
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.

Traffic stopped very quickly. The automatic breaking did not engage, resulting in a crash and a total loss of the vehicle. I bought the Audi due to quality safety features so this incident was very disappointing and costly for our family.

The rear subframe of my Audi Q5 has extensive rot and holes per an inspection done and deemed unsafe to drive. However I’ve only had the car about 3 years. To fix this will cost me around $5800.00.
NHTSA complaint #11685613 — an unverified report by a vehicle owner.
The front subframe has experienced catastrophic failure due to severe and premature rust-through corrosion. Multiple holes have perforated the component, compromising the vehicle's structural integrity. The part is available for inspection upon request. The safety of my family and others was put at significant risk, as the subframe is the primary component that mounts the engine, suspension, and steering rack to the vehicle. A failure of the subframe while driving could cause a complete loss of steering control and the collapse of the front suspension, leading to a serious or fatal crash. The problem was independently reproduced and confirmed by both an independent service center and an authorized Audi dealership. Both establishments have deemed the vehicle unsafe to drive due to this specific issue. The manufacturer (Audi of America) has been made aware of the issue through their dealership network. They have acknowledged the defect by offering a "goodwill" repair to replace the subframe, confirming their awareness of this failure mode. However, the manufacturer has made this safety-critical repair contingent on the owner first paying for several thousand dollars of unrelated maintenance items, creating a financial barrier that prevents the safety fix from being implemented. There were no warning lamps, messages, or other symptoms prior to the failure's discovery. This is a silent failure that provides no warning to the driver. It was only discovered during a routine service visit when the vehicle was on a lift.
