Control modules located next to the gateway module that was recently recalled are getting wet and shorting out. Tail lights, brake lights, turning signals, license plate lights, and reverse lights all stop working. Once the area is dry, the lighting works only sometimes. I am not ever sure if the lights work or not while I'm driving and am concerned about getting rear-ended because of the lights being out and me not knowing.

Having taking the car in for routine service at the Audi dealership, it was discovered that the Right rear spring and lower perch were not in correct position. I had the car inspected by an auto body shop and was told that the perch is hanging down and the spring has tipped sideways. I am having the car flat bedded to the dealer in Hyannis and the next available date on the schedule for the car to be repaired is 9/26/23. I was advised not to drive the car by the dealership until the repairs are made.

My 2018 Q5 has experienced water intrusion due to the defective design of the sunroof/drainage system, causing water to leak into the trunk and rear left cavity where the ECM and battery are located. After several hours of rain, approx. 2 inches was collected in the location of the battery and was extremely dangerous.

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.

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.

Panoramic sunroof leaked water into the car's electrical system during a rainstorm (despite being closed tight), resulting in a total failure of the car's electrical system, potentially a catastrophic occurrence. Fortunately the electrical failure happened when the car was stationary.

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.

As I was preparing to park at my local grocery store in an assigned space I experienced a sudden unintended acceleration. The front end slammed into a concrete retaining wall, causing major damage to both my vehicle and the retaining wall. The car was practically at a complete stop when this occurred. Additionally when I reversed the car it accelerated back at a rapid speed. It was very scary and thankfully nobody was injured or worse. This could have been a serious or fatal situation and I feel that there was some kind of electronic failure. Considering the safety record on this car I felt very unsafe and not in control.

On three occasions beginning in the spring of 2018, the tailgate has randomly opened with no command from the owners. Each time the car has been in our garage and we have been elsewhere. Each time the tailgate collided with the garage door when we opened the garage door was opened causing body damage. A quick google search shows that this is a recurring problem for the Audi Q5 and other models and that this problem has occurred outside on streets and roads as well as inside. The dealer said that Audi has a provided the dealer with a technical bulletin to make software changes remedy this problem. However, even after the software changes, this problem has recurred. Audi has refused to pay for the body work. On the first occasion, I paid for the body work. On the second occasion, the dealer paid for the body work after Audi refused to pay. The car is now going into the dealer for an extended period so that the dealer can work with Audi engineers to hopefully solve this problem once and for all. If the tailgate opens on a highway and luggage falls out, someone could be hurt or killed.

I purchased my vehicle on 4/21/2017, I was sold by the dealership on the advertised safety feature called the Audi pre sense. Audi pre sense detects collision hazards all around the car and initiates specific preventive measures. On 1/20/2018 at 9am I was involved in an accident where I was driving on a city street going about 10-15 mph, I was stopped at a red light and was driving off from the intersection due to the glare in my eyes I was not able to see a cement pillar in front of me. The car collided and there the entire front was smashed in, the engine belt was clipped.I contacted Audi head quarters and described to them the incident, provided pictures, and police report. Audi customer care told me that the safety feature does not work in sunlight and that in this cased the Audi pre sense would not of detected anything. This is far different from what the dealership told as well as what is published on their website. The Audi pre sense should be 360 view and my car should have alerted me that I was in an accident.
