general problems of the 2018 Audi Q5 - part 2

The contact owns a 2018 Audi Q5. The contact stated that while driving his vehicle, a start/stop malfunction warning message appeared on the display screen. Once the contact made it to his destination, the vehicle failed to turn off after repeatedly pushing the start/stop button. The next day, the failure persisted and the vehicle was taken to a dealer where a diagnostic was performed. The diagnostic showed that water had traveled from the sun roof drains into the rear left panel and into the vehicle's wiring module. The manufacturer was notified of the failure and informed him that there were no recalls on the vehicle. The vehicle had yet to be repaired. The failure mileage was approximately 72,000.

Warning lights on the dash began to light up about a minute after starting and driving the car. Pulled over, stopped the car and tried to restart but couldn't restart. Apparently water leaked in from the closed sunroof over night and flooded the spare tire well where a control module is located and shorted. Car was serviced by Audi as recommended during the entire time. Had to have the car towed to an Audi dealer and was charged $1,600 to correct after 10 days.

On 8/8/2023 my vehicle was outside in the driveway of our home in truro, MA. A large storm moved through the area with torrential rain and lightning. Once the rain let up I looked out the window to find all 4 windows down 4-6 inches, the rear hatch was opened with the rear wiper and high middle brake light on. When I ran outside to close the windows etc. I could not start the car the mmi did not come on and I could only get 3 of the windows up. I had to manually close the rear hatch. I put a tarp over the drivers side window that wouldn't close and had aaa come out. They assessed that it was not a battery issue bit an electrical module issue. I filed a claim with my insurance and after waiting for the adjuster to look at the car I had aaa tow it to an Audi dealership. They ran a diagnostic test on it and found water had caused the comfort module and associated wiring to fail. The estimate to fix the issues was is nearly $12,000. Because of the cost my insurance company is sending another adjuster out to inspect the issues at the dealership. There were no prior issues or symptoms before this issue took place.

The comfort control module catastrophically failed. There is video evidence of the condition the module is in. The whole car shut down. Nothing electronic worked. Doors unlocked, trunk opened, gas cap unlocked, couldn't start car or change gears, roll up/down windows, or lock the doors. The dealership has confirmed the sunroof drains leaked water into the rear left wheel well filling it up with water into the trunk where the spare wheel well is with picture evidence of the amount of water. It rained the night prior. There were no prior warning signs or any issues. Everything was working fine until it was not. The comfort control module needs to be completely rewired and the sunroof drains need to be completely replaces. If this happened while I was driving I would have lost complete control of the vehicle as all power to the car was off.

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.

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.

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.

This vehicle has electrical issues. This vehicle waterpump failed twice which I had to repair this vehicle gives warning sign’drive system malfuction’ codes directing to turbo charger but it is actually the wastegate thats the issue-which I had replaced after throwing a new turbo. This vehicle has issues with thermostat which I had replaced twice. I have payed all repairs out of pocket and until today there is no recall. Someone please take a look into this matter any information needed from me or my mechanic I can be contacted via email -: ulbin420@icloud. Com.

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 rain storm 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 rain water had leaked into the rear of the vehicle and the electrical components had submerged in water causing an electrical failure to occur. The vehicle was not yet repaired. The manufacturer was notified of the failure but no assistance was offered. The contact indicated that the vehicle was previously serviced under the NHTSA recall campaign number 21v947000(electrical system, structurer). 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!.

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.

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.

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.

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. .

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. . Read more...

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". . Read more...

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.

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.

Tl the contact owns a 2018 Audi Q5. The contact stated that the instrument panel went blank without warning and the indicators and gauges could not be viewed. The vehicle was taken to mckinney Audi (6650 texas state hwy 121, mckinney, TX 75070, (972) 390-2100) where it was diagnosed that the computer needed patching in the "s 5 chip". The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was 4,392. The VIN was unknown.

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.

Vehicle traveling straight on highway at 70mph with phone plugged in to entertainment system and connected to carplay. Center screen shut off, and Audio controls unresponsive on both the dash and steering wheel. The instrument panel, which was displaying google maps, then blacked out, with only the speedometer and tach displaying. Again, controls were unresponsive. The system then restarted, similarly to initially turning on the vehicle. The "initializing map" message appeared in the instrument panel, and shortly thereafter both the center screen and instrument cluster were functioning normally, and all controls were responsive. This was especially stressful as I was expecting something else to fail but couldn't pull over.

2018 Audi Q5 prestige. Consumer writes in regards to the heads up display function on vehicle. The consumer stated when the sun reached a certain angle, a white solid reflection box appears on the windshield. This created a visibility issue for the driver.
