Dear Sir or Madam: I am submitting a safety complaint regarding my 2022 Audi Q3 involving water intrusion from the sunroof. At approximately 41,000 miles, approximately a month ago, water began leaking through the front edge of the sunroof despite the sunroof never being opened prior to the issue. The leak was not caused by clogged drains or lack of maintenance. Water entered through the overhead console, resulting in failure of the interior lighting system causing lights to flicker on/off and water dripping directly onto me, the driver, while operating the vehicle. These issues created a significant distraction and potential safety hazard, especially during night driving. The dealership diagnosed the issue and confirmed that the repair required modification of the sunroof assembly and track to correct a water intrusion problem. This was not a routine maintenance issue. …

Vehicle was serviced in 2025 for an electrical issue impacting multiple electrical components of car. Approximately one year later the car is back in the shop for both an electrical issue causing lane departure and now lane keep assist to trigger an error. I was told by the local dealership that it is likely related to an electrical module underneath the bumper of the rear of the car. The dealer is franchise and does not share records with other Audi dealerships and therefore unable to evaluate the problem with the prior Audi dealer who identified and repaired the first issue impacting multiple sensors. I was told this current issue seems to be related to a component underneath the harness of the rear bumper, but may be impacting other electrical systems.

By the dome light, it leaks water when it is pouring rain very heavily. It also drips water by the passenger side shade visor. The dome lights will dim and get brighter consistently as it is dripping. the driver side headlight also gets foggy when it rains, which causes the one side of the vehicle not being able to see out from. The rain in the inside goes near the electrical outlets and sometimes gets into it, if i dont wipe the water away. At night time it is dangerous, with the lights dimming & getting brighter , while also leaking from the top as I have to dry it, try to turn the lights off and drive at the same time. No specific date this has occured, it has happened for approximately 3 months now.

Please investigate the 2020 Audi Q3 and issue a recall - this is a major driver safety issue. I purchased this vehicle new from the Audi Crown Clearwater, FL dealership in late 2019. I am taking it for repair a THIRD time because after it rains, the interior gets flooded with water which pours into the car from the rear-view mirror area which affects driver visibility, lights, electrical components, and more. The water damage is visible and there is so much built-up saturation from the leak that it causes the interior touch lights to stay on. …
