Sunroof leaking affecting radios, amplifier, draining battery.

- Port Washington, NY, USA

As many people have already registered complaints about, even with cleaning our sunroof drains regularly, the glue failed causing us to not only endure the expense of a well-documented issue with the vehicle, but now we have been without a stereo since we feel we are entitled to at least that much, however, Audi of America disagrees. Considering how many issues there have been with sunroof leaks in the past and the fact that this is an ongoing problem for Q7 owners, I feel, as many others do I'm sure, that this problem needs to be looked into further by the NHTSA.

Draining system in the roof of vehicle seems to be a design/engineering flaw. In under 4 years, water leaked into the interior front and rear of car causing issues with the amplifier and who knows what else. Dealer says it was not covered under warranty and estimates $1600 to fix the drain issues and $2200 for the blown amplifier.

Following an exterior car wash (brushless) the audio system and mmi began having problems. The rear audio speakers began crackling and then stopped working altogether. Certain mmi controls, particularly with the heated seats and fan blower also stopped working. After some time, the speakers returned to working but the mmi system remained spotty. No battery draw was found and no apparent (obvious) water intrusion was found.

My 2007 Audi Q7 SUV has electrical issues from a spilled drink from the cup holders. If liquid travels directly below from cup holders, the mmi circuit board that controls the headlights, wipers, ect, stops working from sometime or not at all. It starts with the radio and then the windows, ect, and then moves to the headlights and the wipers. Audi says it is the owners' problem and is not covered under warranty.

My car was purchased new on August 31, 2007 and has 20068 miles on the odometer. 1. during a thunderstorm, I entered my car and placed my umbrella on to the passenger seat and got into the drivers seat. Some of the rain water dripped off the umbrella and onto the face plate of the mmi control unit located on the center console. Within two weeks the mmi control unit shorted out and failed. This failure stopped many of the electronic functions the mmi unit operated, ie., the gps nav. System, the radio, the blue tooth telephone, the operating controls of the auto, cd, vehicle settings, the windshield wipers (front& back) and all the rest of the controls the mmi system operates. 2. the failure seemed to be permanent. I was unable to operate all of the functions from this controller. 3. I contacted the Audi dealer in buffalo, NY and made an appointment for service. I was told that this was a warranty component under the auto warranty. I arrived at the Audi dealer service desk and explained what happened. Where in they advised me that if there was any moisture from water, soft drinks, coffee or tea spilled onto this control unit, it would short out electrically and cease to operate. The service person stated that the Audi limited warranty (4 years or 50,000 miles) page #4 of warranty manual: Items that are subject to adjustment, such as wheel alignment, tire balancing, headlights, door, shift linkage, and sunroof adjustments, not caused by outside influence or normal wear are covered one time within the first 6 months or 6000 miles whichever occurred first, etc... I explained that this mmi did not need an adjustment...it failed and had to be replaced. They would not cover this $800 plus dollars to replace this unit. In order to drive the car safely, I had no choice, I paid the amount. The old part is available. I told them that the car manufacturer made a design and engineering error in not waterproofing this control unit.

The contact owns a 2007 Audi Q7. The contact stated that there is a computer system that controls all of the electrical devices in the vehicle. The system is located directly underneath the cup holder on the arm rest. The wood trim is inadequate and does not seal the computer module, which allows liquid to enter into the computer module. As a result, the electrical devices will malfunction. The contact took the vehicle to the dealer and a technician stated that it would cost $900 to repair the computer module. The vehicle was repaired, but the failure recurred several months later. The manufacturer did not provide any assistance. The failure mileage was 7,000 and current mileage was 17,500.

In August of 2006 I signed a three year lease for the new Audi Q7, 4.2. right from the start, I encountered a potentially very dangerous problem. When coming to a stop and then trying to accelerate the vehicle failed to move. Only by removing my foot from the accelerator and then applying full pressure will I start moving again. This was not a lag nor a hesitation, since without removing my foot from the pedal the car simply will not move. Depending on the brake to accelerator or accelerator to brake sequence, the car will either come a fully unresponsive stop or fail to shift from second to third gear. The dealership initially denied the existence of the problem. Now, after having had the car test driven several times and after having been in constant contact with representatives of Audi and I am being told that this was not the car for you. Should have not bought this car if you drive with both feet. I have not found this warning in any publication. Audi of America's explanation was that the drive by wire system will shut down the fuel supply when the brake and the gas pedal sense just the slightest pressure at the same time, causing the car to stall in the middle of traffic. Audi has not issued a software correction to the problem. I test drove the same model Q7 recently and it behaved the same way. By driving this car, I am exposing myself and my passengers to very dangerous situations on an hourly basis.coming to a stand still in front of oncoming traffic was a death sentence. Even though Audi admittedto the problem and offered their scientific explanation to the sudden fuel supply shut down, the representatives told me that the vehicle performed to manufacturer's specifications.
