2018 Audi Q5

Rear Sunroof drain leak into major electronic components. 2018 Q5 with 61k miles after heavy rain started receiving all kind all errors including lights and ignition. Upon inspection Audi service has stated that HVAC control module has shorten (the area with the module in the left rear portion of the trunk filled with water), quoting repair of the module and insisting to replace sunroof drain hoses for total of $5k. Insurance has agreed to cover module replacement due to the flood of approx. $2,5k, however drain hoses and deducible with another $2,5k would not be covered and is on me. Mechanic in the Audi service several times noted that that this is common issue with Q5 and Q7s., I am so frustrated and do not understand how come the Audi car the owner shall be responsible for any cost of such if it is unclear: 1. How and why the water gets there through the closed sunroof in such amount to flood electrical equipment. Are all Audi sunroof seals so bad that they fail in 6 years? 2. I had serviced the car in the Audi for up to 60k, and no one ever cleaned the drains there or advised me of such (all is needed a small note for me)? Why did I pay extra to service car in the official dealerships? 3. How Audi could sell a vehicle with such design flaw, placing weak drainage hose through the electrical equipment compartment, considering they just had a class action lawsuit over sunroof leaking but on different models and model years.

Hello, On September 29, 2023 while I was driving my 2018 Audi Q5 a light come out "Steering malfunction! Please stop vehicle". I called the Dealer Audi Arrowhead in Peoria, Arizona, and schedule an appointment for October3, 2023 to do a diagnose. I drove the car throughout these days and I have not notice anything wrong with the car, except that light. I went to the dealer they proceed the diagnosis, gave me the code C101C07, and the quote to do steering gear replacement. I asked them: if the car is drivable, is just that light on the dashboard, why you can not do a software update? Because they refused to do that, I called Audi USA, and after a few days of back and forth communication they refused to do the software update and agreed to participate with the repairs and cover 50% of the repair cost. I pick up the car from Audi Arrowhead (they did not provide a print out result for diagnosis, also no bill for diagnosis) and I called Audi Scottsdale and because they confirmed me that they can do a software update I decided to bring the car in their shop and have again a diagnosis done. The same code was founded and of course they refused to give me a print out result, and I got charged $210. Even they admit the car does not show sign of something broken, telling me that it is possible that it will never show signs of failure they refused to do the software update. Because it doesn't make sense to me that the car runs perfectly, as always, only the light is on in the dashboard, I ask you to help me and intervene by asking Audi to issue a bulletin to update the software on my 2018 Audi Q5. Thank you in advance!!!

The contact owns a 2018 Audi Q5. The contact stated that vehicle failed to start. The contact stated that while replacing the battery, he observed condensation near the wiring. The vehicle was taken to an independent mechanic where the vehicle was hoisted up and there was condensation draining from the driver’s side of the vehicle. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 48,000.

Suddenly car entry stopped working. Warning messages on display about start/stop, engine starting malfunction, every single light. I found the driver rear side full of water where the fuse panel and control modules are located. There was water soaked into the insulation at the bottom of the space as well as the insulation over the wheel well. Water drops were viewed on the controllers in that space.

My vehicle's drive side (front) door has an ongoing malfunction of the handle. The protective covering continues to fall off and I am concerned that it will fly off and injure someone. I've taken the vehicle to a certified Audi dealer (Ciocca Audi, State College, PA) on at least three occasions and they are unable to fix this problem. In fact, they state that it's a "known circumstance" with all Audi Q5s and perhaps other models and forwarded videos to me documenting the same issue on 2023/2024 models. They are unwilling to find a solution; thus I continue to drive an unsafe car. I am requesting an investigation and a safe solution.

Sunroof drain canals had a defect that caused water to leak in the back of the vehicle (from the C Pillars) and caused water to accumulate in the trunk - about 2 inches. Water damaged several electronic components, modules, and the battery causing the car to send multiple alerts to stop driving immediately. This seems to be a common issue but there are no official recalls or extended warranty from Audi.

Comfort Control Module (J393) is malfunctioning due to water getting into the wiring components and surrounding areas. The rear lighting stops working all together; No taillights, no brake lights, no turn signals, no license plate lights, and no lights when backing up. The problem has been reproduced by an authorized dealer. The component was removed by the dealer and noted of water inside the module and corrosion on the pins/ internals because of the water. The warning lamps occurred at the same time the lights stopped working. There was never any "prior to" warning. The warnings disappear randomly, no set time until they cleared. I am assuming once the module dries out over time is when the warnings start to clear but that is just speculation. UNKNOWN cause of the incident, but water is getting into the inside of the car somehow.

Start/ Stop system malfunction shown on dash board. Took vehicle to Lynbrook Audi New York on 9/20/23. Water penetration causing multiple damage to electrical systems. Audi states water possibly entering through faulty skylight drain hose ? Quote service charge of 12,028.00 not including tax , declined service for a second opinion. Invoice # 207805. Paid 271.57 for diagnostic inspection. Vehicle was service at this location on 3/9/22 RO # 188998 Tag w107 Complete Complimentary Inspection on 3/9/22. Vehicle Certified ( pre-owned ) at this location on 12/20/2020 ( paid over 1,000.00)

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.
