I currently own a 2007 Audi Q7 3.6 and believe there is a safety issue with all 2007 3.6 vehicles. The vehicle is advertised to have the towing ability to tow up to 6600lbs. On three separate occasions while towing a 435lb aluminum trailer the check engine light came on along with the epc (electronic power control) light and the car goes into a safe mode which will not allow you to go over 3000rpms. This problem only occurs while towing for over an hour but when the safe mode is installed the car has no power and with a trailer still hooked up the car has trouble going over 45mph. This is a very dangerous situation especially on the highway when trucks are passing you doing 70mph. My Q7 was in the dealership three times for this problem and I'm still not satisfied that the problem has been corrected. They downloaded new software to my engine control module which changes the performance of my car but I believe anyone who owns this same vehicle and attempts to tow will find themselves in the same dangerous situation. Most people don't use this type of car to tow with even though they advertise this as a selling point. All 2007 Q7 3.6 vehicles should be tested and have the updated software installed in there car before someone gets hurt
