I purchased a new Audi Q7 S-line in 2011. Multiple repairs and recalls during and after warranty period. Electrical is particularly problematic. Changed first sensor door handle in 2014, under warranty. Now, with just over 70,000, all four handles failed, had to replace new battery and all four handles, total cost over $2,500. Clearly a manufacturer defect and if you search you'll find multiple complaints about the problem, so I called Audi customer service. The car was always dealer-maintained and repaired, with all records, but they've been "researching my inquiry" for over a month now with no decision. Not what I would have expected of a "premium" car brand. Recommend they issue a tsb

This complaint pertains to Audi adblue(nox) system. We recieved a fault on a road trip. It stated car would not turn on within 600 miles. It started to count down. After 3 dealership visits they informed me that the first part to replace is a nox sensor to the cost of 1300 dollars. I refused as I didn't have that amount. So now I have a car that cant be driven because it wont turn on and comply with federal emissions. I feel that if there is a part having to do with federal emissions then Audi should have to be forced to replace it like they would a catalytic converter. Or not disable the vehicle in case I'm in the middle of nowhere!!!!!! Audi should remove that programming, given the fact that in a state of emergency I would appreciate the ability to continue driving for months or years(if need be) if the country is lacking infrastructure. Another scenario would be if I decide to drive all the way to the southern tip of South America. I would hate for my car to be stranded because of a not so critical issue.
