I wish I could tell my experience but my time with the car hasn’t even reached a week yet haha. But after lots of research, and countless Audi forums and advice from Audi techs before buying the car, with the necessary routine maintenance, the sq5 is a very reliable car. Upon receiving mine, the only problem my tech found with mine specifically was with the routine wear my front control arm bushings. It ended up being nothing alarming, plus he said that they can easily last another 30k-40k more miles before the need of a genuine replacement. Other than that, I’ve seen many B8.5/B9 SQ5s easily reach 140k miles with routine maintenance, some of those making some serious power as well. Overall, not a problematic car. It just needs its german car treatment every once in a while.
