I purchased the car used in 2015 with 35K miles. Since then, its been over eleven times regarding water leaking issues, particular involving the sunroof drains especially the right rear drain over the passenger quarter panel window near the airbag area (C-pillar). The headliner had to be replaced at least once (it should have been replaced other times, but the dealership only cleaned the stains). The sunshade had to be replaced/repair twice because it was damaged during manipulation of the headliner, and the sunroof had to be replaced because it was damaged, and then subsequently adjusted due to squeaking. This sunroof continues to have drainage issues after a heavy rain, which results in water leakage onto and staining the headliner. Each time the dealership states that the drains were blocked and needed cleaning, but the car is mostly garaged kept and is not exposed to a lot of tree litter. I asked if there is a permanent fix, and I've contacted Audi usa regarding this issue asking for a permanent fix or repurchase/replacement of the vehicle to which they response was no they can't help me or resolve the problem. They suggested that I work with the dealership service manager, with whom I've already worked with and they've been helpful, but if it is a design flaw, then Audi usa should do something to correct the problem permanently or buyback the vehicles and make their consumers whole. I am concerned about rusting, compromise of the side airbag (C-pillar), and future deterioration of the headliner. But also the inconvenience and frustration of taking the car into the dealership after a heavy rain (52mi drive one-way) to deal with a leaky roof drain. Please help, initiate a recall so consumers can be made whole by way of repair/replacement or re-purchase of their vehicles this would show auto manufactures that they cannot take advantage of consumers.

Right side (passenger) door latch/lock mechanism failed. Because the lock failed, the alarm system does not see the door as closed and will not arm the system. Subsequently, the door cannot be locked unless you activate using the child proof overide near the latch mechanism. You must reach in through the drivers side to open the door using the handle. This is a safety and security issue that should not happen on any car with less than 55K miles on it. The Audi forums have numerous complaints about this issue with the B8 model car (A4/A5/S4/S5/RS5). Additionally, the dealership wants to charge over $650 for parts and labor. This may be a diy if you are very skilled (read: A mechanic) and if you have the right specialty tools. Additionally, the part alone costs $200 for a new replacement. Used parts are available but if the failure rate is close to the 50-55K mile mark, not many of these are available and those that are available are questionable with regards to reliability. I have asked Audi America (usa) for good faith assistance but they have remained silent.

Keyless door sensors started to malfunction and would not unlock vehicle when touched. Brought problem to attention of dealership, which stated that they could not duplicate problem and thereby refused to fix issue while the vehicle was still under warranty. Now that the vehicle is no longer under warranty, the problem was found and the cost has to come out of my pocket. There should be a class action lawsuit regarding these keyless door sensor failures.
