Selected complaints filed with NHTSA by 2007 Audi Q7 owners, lightly cleaned up (personal details are redacted by NHTSA).
Water leakage into the driver's side floor panel. Water leakage seeped into battery compartment below driver's seat which is a result of a sunroof drain problem. New Battery was installed for only 3 months before the low battery charge warning light came on. Car will not start at times. Water leakage into electrical components that lead to the MMI not turning on or working at all. The MMI shut off first, then the battery became faulty. The car has been jumped at least 10 times due to the water damage, which proposes a risk to the driver. The electrical components are being flooded, which is a safety issue and proposes a safety hazard to the driver and all passengers. The electrical is at risk for further damage. This problem has been reported by others many times. …
This started happening in the last 2 mos. My MMI started acting up, it first displayed radio not installed, then it would stall and not show anything on screen, then it came back on to regular showing but then went out again and displaying radio not installed. Then at one point I was able to play my CDs but not my radio. Then finally the complete system went out, now the screen only shows the MMI logo and will not turn on and cant not be reset. So as this has happen, my fuel tank area started to drips tiny drops of gas only happens when I drove it, so now it is leaking even more fuel so I have it sitting in drive way until I get it into the shop. While its been sitting in the drive way for the last 2 weeks, I would occasionally start it but this last time I started it my battery went dead and it started leaking even more gas after I got it jumped. …
This is a known typical problem with these suvs. Rear sunroof drain leaks directly onto amplifier causing electrical issues throughout the entire vehicle. My vehicle actually filled up with smoke when it dried the amplifier. All mmi functions are lost. Why has this not been fixed by Audi on their dime. Dealer wants almost $4000 to fix the problem. What does it take to get a recall for this. An electrical fire or loss of life? This is the second time I've had this issue
Electrical issue due to the faulty sunroof water drain hoses(connection for hoses). Like all (all) Audi Q7 owners I have encouraged problems with my complete electrical system in the car. Water leaked from sunroof down to most electrical components in the car which are hidden behind upholstery. Audi is full of electronics including safety systems in the car. My mmi system died due to amplifier getting wet. After mmi, battery drained out after just 7 hours that car has been sitting in the parking lot. All dealerships know about this and Audi is still ripping off all the Q7 owners on this issue. Too bad is that in long run they will lose a lot of customers.full repair of sunroof hoses and replacement of Audi amplifier which is first part that gets affected from water costed me almost $4000. Not to mention that I still stains from water on my roof liner. …
The rear sunroof leaks around the seal and leaks down into the electronics of the car. The drain tubes are ran through the electronics compartment causing it to short out the system and causing the check engine light and tire sensor lights to come on and not be able to be reset. The sunroof not only leaks from the drain tubes but also around the seal, also causing the water to drain into the electrical compartment which causes the same issue even after the drain tubes are repaired. You can find this issue listed all over the internet help sites as well as you tube. This is a very common issue with this model vehicle, and is a design flaw that Audi is refusing to fix and passing on the cost to the consumer. To repair the amp and water leak is upwards of $6000. The consumer should not be responsible for assuming the expense of a manufacturer design flaw. …

There seems to be leaking from the sunroof that lets water into the amp. The leak goes into the amp and causes the battery to drain when sitting. This issue has been known by Audi for a while and have not done anything to recall these vehicles and fix the issue. The average cost to make the amp and roof repair is $4,500. Please look into this. Thank you.
