The moonroof was very poorly designed/built. It clogs very easily and forces rain into the battery area. Other than that, it goes into the footwells and the comfort control module is beneath the drivers footwell. Soaking in water destroyed it. Now the windows don't go up or down. The moonroof refuses to open or shut. The car will not lock or unlock with the key. The car has sat now for too long and will no longer even turn on. The insurance company looked it all over and denied my claim. The vehicle has pretty much been totalled. Even after paying professionals to clear out the clog, there's still massive problems with it.

They have a design defect which allows water to get into the cabin via the moon roof. They also have an electrical motherboard under the drivers feet (comfort control module) that shorts out when it gets wet (which is easy when the rain comes in from the faulty moon roof). Now I cannot un/lock my doors, operate my windows open/closed, etc. And I believe it has negatively effected my ability for brake lights to function properly. This is a widespread issue, not just on mine. They were even class action sued for the same issue with a different year model (and settled out of court, but I was not an owner of the other car year). Please help. Thank you.

So I opened up the sunroof, took a long wire and started poking. I also removed the wheel arch and cleaned out the outlet. I poured a bucket of water thru and it came out of the bottom nicely. All well I thought. Today it rained for the first time since then, and I was very unpleasantly surprised to feel waterdrops dripping from the hood opening grip next to my feet. Since my car is always outside and not covered against the rain, I had to deal with it right away. I stripped the a pillar cover and saw it had serious water marks. Obviously the water had been dripping slowly for many months already. It just never got worse enough as you can see in the picture the green hose is the drain, and it has a brown stripe down the bottom from long time dripping. The leak seemed to come from all the way up to where it is connected to the sunroof drain pipe. I pulled it loose and the hose is fitted to the pipe with soft plastic connector. The connector slides over the pipe, but the hose is glued to it. Now the glue is exactly what caused the problem! the glue had gotten brittle and had cracked, it seems like Audi used the wrong glue for this hose. I cleaned it, glued it back together and poured another bucket of water thru, but now while the lining was still open and the hose fully exposed. No drip at all! I must say, this problem was a very nasty one, it really bugged me very much to get water in the car, especially because it can do so much damage. Attached is a picture where you see the roof airbag which was totally wet also. A picture where you see the green hose with the drip marks, and a picture which shows the left side of the dashboard with the fuse box exposed, if you look closely, you see the steel is rusted, since the sunroof water draining is a very wide spread Q7 problem I would advise all owners to check the fuse box.

When driving my car has what is and should be a recall with the given number of complaints regarding this issue of "right or left dipped headlight." Audi of America is quite aware but this is not just any recall this is a safety concern and like windshield and airbags should be looked into quite seriously.

Traveling on the freeway at 60mph. The esp(stability control) and epc lights came on. 5 seconds later the engine shuts off and I keep rolling at 60mph but decreasing speed. Luckily I was on a straight away and there was no need to turn but once the engine turned off the steering wheel was hard to turn and I could not pull over. There was an exit and I was able to stop on the off ramp. After putting the vehicle in park. I took the key out then, put it back on the ignition and tried to turn the vehicle on. The vehicle would not turn back on. When it finally turned on the vehicle stalled back off and the "check engine" light came on. After sitting in the vehicle for 5min in off. I then turned the vehicle on and it started off. I went to the dealership and told them what had happen they told me that it had never happened before with other Audi's but that it sounded like it was the crank shaft sensor. After looking online and doing research many other Audi owners had the same problem they stated that the "engine speed sensor" aka crankshaft sensor would go out and their engine would stall while driving. This is a safety issue! airbags go off when the engine shuts off and the steering wheel is hard to be turned. Please do something about it!

On 6/10/2014, I drove my 2007 Audi A4 a few miles to a local business and parked. On attempting to restart the car I found that the ignition key spun in the ignition cylinder assembly. It took approximately two minutes of spinning and light pushing for key the mechanism to reengaged, and the car to restart. During the time the key was spinning it was fully engaged with the lock, but spun in-place with the engine not starting. Took car to certified Audi dealer on 6/16 for diagnosis and the recommendation to replace the ignition cylinder assembly. Contacted Audi of America on 6/30 regarding safety incident.

I purchased the car in 2013 the key was very difficult to turn in the ignition, after 3 months, it locked up one time in the garage so I just left it as it was and tried the next day. After yanking on the steering wheel and almost breaking the key in the ignition it finally started. A week later I was out shopping and it did the same thing - tow truck driver had no way of even towing the car because the wheels were cocked to the right, key would not come out of the ignition - the steering wheel was totally frozen. A mechanic came and got the wheel to move in turn allowed the car to start I had to leave the car in neutral with the key in it for weeks while we researched this issue. I called the dealer who sold me the car, they told me it was probably the ignition switch needed to be replaced - I asked them why this was not checked before they sold me the car they insisted it did not show up in the diagnostics for a certified preowned Audi I took the car to mechanic. After 7 days tearing the whole steering column out they found the wheel locking mechanism and the key/ignition switch was broken also the airbag light would not go off. After more research the mechanic found reports on the faulty, ignition switch, airbag light and the worst the wheel locking mechanisms which some people had this happen while driving causing accidents. I could not find any recall info and this cost me a lot of money, time and anguish. Audi would not even perform the diagnostic on the car without an up front cost, also the airbag light would not go off after it was taken out and put back in it must be reset with a special Audi tool and they charge for that as well. Seriously I am afraid to drive the car now because if this happens on the highway I could be dead from their lack of concern for safety my Audi is a convertible all wheel drive - should I take out a life insurance policy?

While driving my 2007 Audi A4 three times over the course of the last month my car has died while driving. Once on the highway, once on a local road, and a third time in a parking lot. All three times Audi claims that "no error code was recorded" yet the check engine light and electronics error light turns on. Because they can't replicate it or see an error they are refusing to do anything to help me other than test drive the car. What evidence do they want" would me in a body bag after my car quits on the interstate again be what it takes to convince them something isn't working"
