In early July, 2023 various warning and fault lights began to show on the dashboard: engine start system, brake lights, start/stop system, and others - indicating malfunctions with systems important to safety. Also, the car alarm system sounded without cause and key pods would not lock/unlock the doors electronically. These warning lights proliferated over several days. We took our car into our local Audi dealership. They diagnosed the problem as follows: "Performed GFF and found code for 3393 comfort system control module replacement. Control module faulty due to control unit being submerged in water and fried the control unit. Water leak due to rear drains clogged causing the water to overflow. Performed/fixed the water leak, cleaned out the pools of water that have accumulated, replaced the control unit 3393 comfort system control module, performed control unit replacement test plan and program keys." The Audi Q5 is well known to have design/parts problems in the sunroof drainage system. As has occurred in thousands of other Q5s, those issues caused the rear cargo area to flood, frying an important electronic component and activating warning/fault lights for a range of other systems. Malfunctions in several of those systems could have caused critical safety issues. We are fortunate because we decided to take our Audi directly to the dealership service center. Repairs cost several thousand dollars.

Regarding my 2018 Audi Q5 34000 miles. Driving on a busy highway a few ounces of water spilled in the backseat. Car lights up like a xmas tree and car came to a screeching stop. Two lanes of high speed traffic on both sides. Fiance just had both hips replaced, Ends up popping one of them out of socket during ordeal. Recall was issued for installation of 'protective cover' over gateway control module. Car received recall work. Part still failed. Audi won't cover the part. I'm out of warranty. Total bill $1800. Dealer has had car 3 weeks. I've been out of pocket for rental car

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 car is totalled. My car tripped 9+ malfunction warnings, after starting and driving. These included rear brake lights, directionals, start/stop system, and more. It appears that the sunroof leaks, and the roof drains were clogged (even though they were specifically checked and cleaned by the dealer 2 months earlier). This led to water accumulating in the areas under the back seat (a prior recall which allegedly had been addressed...NHTSA campaign number: 21V947000. Audi-??s number for this recall is 90S9.), and in the rear wheel well area, where electronics control modules live. The car eventually had to be towed to the dealer. It was initially estimated to cost $9,500 to repair. But, after several weeks, more water was found and it was declared not worth repairing.

The contact owns a 2018 Audi Q5. The contact stated that while starting the vehicle in a severe rainstorm, the vehicle experienced electrical failures, which included the head lights flashing and the horn activating before the vehicle suddenly became inoperable. The vehicle was towed to the local dealer who discovered that rainwater had leaked into the rear of the vehicle and the electrical components were submerged in water causing an electrical failure. The vehicle was not yet repaired. The manufacturer was notified of the failure, but no assistance was offered. The contact stated that the vehicle was previously serviced under the NHTSA Campaign Number: 21V947000 (Electrical System, Structure). The failure mileage was 53,000.

My 2018 Audi Q5 has a water intrusion issue with control module damage. The vehicle reduce speed to 15 mph on the highway, when parked the lights would not shut off. The vehicle would then not turn on. Thirty minutes later the vehicle started. I received a front passenger seatbelt malfunction and several controls went out. The passenger seatbelt would not recognize there was a passenger buckled in the seat. The lights stayed on. The windshield wipers started on their own. The car wouldn-??t recognize the key fob. Later the turn signal malfunctioned, along with the front lights staying on but the rear light and license plate light would not come on. At the dealership they found water in the comfort module housing, left rear quarter panel/wheelbase and said it was probably caused by the pressure vent seal allowing water to enter damaging the comfort module and 56 wires. They stated the vehicle was unsafe and inoperable. They also were not able to roll the windows back up or lock and secure my vehicle. The issues with the vehicle speed occurred 5 weeks ago. The dealership changed the thermostat but the speed reduction happened again afterwards once but when it was turned off and turned back on the speed went back to normal. Then today the vehicle just went crazy with things turning on and other controls not working, like the taillights. Multiple times I have told the dealership of the seatbelt malfunction. They said it was probably the seat detecting something on the seat, like a bag but couldn-??t account for the malfunction when the seat was occupied. The vehicle is now at the dealership with plastic taped around the opened windows and unsecured since the locking controls will not work. They suggested I file a claim with my insurance for the repair. This screams defect to me!

Have been receiving an intermittent warning: Safety malfunction for the passenger airbag. The light comes on intermittently. Comes on most often when no one is sitting in the front passenger seat. If I place a small bag (handbag, purse etc.) on the seat sometimes the light goes off sometimes it does not. If someone is sitting in the seat the malfunction light is not present. The dealer confirmed the malfunction stating: They found the safety malfunction light is being triggered by a faulty passenger front seat pod and needs to be replaced for $2,233. Doing a quick Audi forum search have found numerous individuals with similar complaints and many have even reached out to Audi. This appears to be a significant safety issue as it calls into question the reliability of airbag operation in the case of an accident.

On 02/14/2022. Car just died while waiting for cars to pass to turn at light. Dashboard started flasing "engine start system: malfunction! - Please contact service" then "Parking Break Malfunction!" then, "Steering: Malfunction! - You an can continue driving" Panicked because was holding up traffic. After a couple minutes trying Car then just started drove home and put on battery charger overnight. Hoping that's all it was. Next morning 02/15/2022 started right up early morning no issues to be concerned with was on highway doing approx 69 mph, drove approximately 42 miles then then while only driving 35 mph 4 lane highway. Again, No warnings, but while DRIVING Engine and steering, just shut down. Almost causing me to be reared and then hit on passanger side. I don't even want to think what could have happened had this happened on interstate or if my children were in the vehicle. It was a very dangerous and scary situation even happening while only doing 35 mph. This should be considered a MAJOR recall. Vehicle was towed on 02/16/22 to Clearwater Audi. We did not receive vehicle back until after over 9 weeks, 04/22/22. Yesterday, 06/07/2022 Sensors glitching again and being called back into dealership. I want this life threatening recall documented. There is absolutely no reason why a well cared for vehicle with less than 18,000 miles should be having these issues. We We keep losing out on time from work and driving back and forth to dealership. We need to be able to rely on the safety and integrity of this vehicle not only for the driver/passangers but for the safety of others on the road. Thank you for your time to hear our concerns

It says driver system malfunction. Day before that it says Auto Start and Stop malfunction failure. When you are the traffic light and slow down and take a turn then the car gives kinds of couple of pushes as if the It gearbox is not able to adjust the speed automatically. You need to accelerate to keep the balance of the Car. Every passenger of the car feel the same. After 2 days I started getting Driver system malfunction warning. The car is not safe to drive on highways or local road as gearbox has some issues. There is a class action lawsuit for the similar problem which Audi did not address yet. https://margarianlaw.com/audi-class-action-lawsuit/

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. The part that was damaged is DIRECTLY below the cupholders and has no effective liquid protections - what did they think would happen!

There is a module under the back seat called the J533 that I am told got wet. This completely shut down the entire car as my wife and child were driving down the highway. We were very disheartened to find out that this is an out of pocket expense for a common thing to happen in the back of an SUV. After searching online, I came across this link, which is an identical account: https://www.audiworld.com/forums/q5-sq5-mkii-discussion-218/control-module-ruined-moisture-corrosion-3001605/ I'll highlight one area in this link thread, as it most strongly relates to your questions above: "Audi (VOA) faces considerable legal exposure for any injury caused by a liquid finding its way into a component that poses such a high risk of harm if the module fails.. which evidently it does via corrosion following moisture intrusion of some sort. This is particularly the case given the absence of any mention or warning in the manual about avoiding spillage, and more pertinent to liability, Audi-??s failure to anticipate the considerable risk of harm stemming from a readily foreseeable occurrence, ie, spillage. To frame it in more stark terms, no one reasonably expects to face a death ride when they spill their soda."

I was about to get on the freeway when my car's electrical system failed and I got several warning lights. The braking/stop start system, lights and a few other lit up. I pulled off the road and had it towed. The dealership said water (rain) got in through my sunroof and shorted my system (warranty won't cover). There are several class action suits re. This issue already and Audi knows about it, but there's no recall and cars have stopped suddenly on the freeway. It's very dangerous.

Car suddenly tied while driving in city; engine/all systems shut off. It took several hours for roadside assistance to arrive, and the 1st 2 towing companies could not disengage the braking system to load onto truck! once vehicle towed to Audi dealer, their diagnosis was "gateway control module J533, water in control module, corrosion in connector, causing fuse for gateway control unit to blow" we were told by dealer that "liquid must have spilled into area behind rear seats". we have no young children, and nobody was recently sitting in rear seat. Vehicle is parked in garage and is in excellent condition; 2 years old / 24,000 miles. This was a $3,200 repair not covered under warranty. This sounds like a design defect. After several communications I had with Audi usa and local dealer, those (2) parties told me this repair would be covered as a "goodwill adjustment" not a "warranty item". I found similar reports online: Here is a discussion I started on an online forum: Https://www.audiworld.com/forums/Q5-SQ5-mkii-discussion-218/control-module-ruined-moisture-corrosion-3001605/page3/ another one I found: Https://www.audiworld.com/forums/Q5-SQ5-mkii-discussion-218/complete-engine-control-module-failure-2952745/ attached is invoice. System will not allow me to upload photos they sent me due to file sizes. Repair took almost a month to complete. We ended up renting a car for a week-long road trip as the dealer loaner is only for local use.

Navigation locks up, driver cockpit and dash screen shuts down when carplay is activated. At time the car doesn't recognize carplay. Additionally the volume control will only increase and not decrease volume. Sometimes it says speech recognition not recognized when adjusting volume. Has not resolved for the 10 months I have owned the car.

I've had several issues with my vehicle when backing up and the presence going off without a reason. When backing up on several occasions, the sensors will beep and bring the vehicle to grinding stop. When I check the area, there are no vehicles, person, or objects in the path of the vehicle. Recently, when driving on the highway, the pre sense went off when no vehicles were around and slowed the vehicle down at a rapid rate. Twice when driving, the pre sense will activate and bring the vehicle to a complete stop when there are no vehicles in front, behind, or beside me.

I was driving 65 miles an hour on I-95 in the left lane approaching the exit for I-695 North on Saturday, January 4th at 5:00pm. It was raining. No one was in front of me or behind me when my car dash lit up with an Audi pre sense red sign on a black background. The brakes stopped the car suddenly on their own and my seat belt slammed me tightly into my seat. Fortunately no one was behind me or this could have caused a multi car accident. There was nothing visible on the road to set this system off. Monday morning I went to the dealer to see if they could disconnect this system since I was now afraid this would happen again and I would not be so lucky with the traffic situation the next time. They lowered the sensitivity but they could not disconnect the system. I also called Audi to inform them about this hazard. They noted it on their record but said it is part of the car and it could not be disconnected. When I looked on line there were many complaints about this problem; however none of the other drivers were on the open highway full speed ahead. Can this problem be looked into before someone's car causes a major pileup with serious injuries. Thank you!

5)establishing a bluetooth connection is intermittent with a samsung galaxy S9. Often the mmi will indicate that it can't connect. If the car is in reverse with the parking assist displaying the rear view camera, the bluetooth connection screen can suddenly appear replacing the rear view image while the car is actively backing up. The rear view camera image is no longer available while the vehicle is in rearward motion. This has happened on multiple occasions.

On multiple occasions when driving the Audi Q5 the pre-sense engages inappropriately (no trigger) resulting in an immediate and harsh braking of the car to a complete stop. In traffic, this poses a significant risk of a crash resulting in damage and potential bodily injury. The Audi pre-sense is designed to stop a car from an imminent crash, however an apparent flaw in the technology engages the pre-sense without totally unnecessarily (no cross traffic, at least 10 feet from a bush or other object). Not only does the unexpected and unnecessary hard auto-braking add wear and tear to the brakes and suspension, it poses a real risk of an accident as other drivers do not expect the sudden and unnecessary braking. This happens intermittently without a pattern in dry and wet weather on a flat surface or an incline. Always occurs when in reverse.
