Well, I had a 2013 Q5 2.0t that I took to 98k. If it wasn't for the extended powertrain, I would have had to pay for 12,000 in repairs. The clip for my sunshade broke 3 times and my interior started peeling.Genuinely surprised to hear this about Audi. I've owned four of them in the last 20 years and unless you get one that has a specifically lemon-y component, I found them to be amazingly reliable. Just traded in my 2017 Q7 with 70k+ miles for a '21 Macan GTS (love it so far!) and only ever had to take it in for one unscheduled maintenance issue, and it had nothing to do with the drivetrain. (as an example)
Dad's 05 S4 had many problems that led to him selling it when he hit 78k.
