2015 Audi A6 / S6 Reliability And Durability: Neutral
YearComment
2016 I wavered on whether to include reliability among the reasons not to buy an Audi A6, and ultimately did not because the issues here are largely potential ones. As it ages, the 2016 A6 could prove troublesome. The 2012s, after a good first few years, have been requiring more than the average number of repairs lately. But over the past year the 2013, 2014, 2015, and 2016 all have been good. Will this change as they near the end of the 4/50 factory warranty? Perhaps, but this remains to be seen. Or not. In general, recent German cars tend to be good for the first four to six years--the latter the point at which CPO (certified pre-owed) warranties end. I often suggest that there are two smart ways to own a German car: under warranty, or if you're willing and able to perform most repairs yourself. And the Cadillac CTS? We have a limited amount of data on the current car. What we do have suggests that it is more troublesome than the Audi. full 2016 Audi A6 / S6 review
