My 2023 Audi SQ5 Sportback's key fob stopped working, and when I took it into the Audi dealership they said that it is a known issue that if you don't unclog the drain (not sure where that is - was never told I needed to do so) then there can be leaks that affect the wiring and the Comfort Control Module, rendering the vehicle unusable. They are now trying to charge me approximately $16,000 to fix the vehicle when it is obvious that this is a manufacturing defect not present on other vehicles. I know there has been a recall for other Audi Q5 models, and it seems that the new generation of Audi Q5 has the same issue. I have also seen online that this occurs quite often to other Audi SQ5 and Q5 owners.
