Auto Express's reliability ratings are based on our Driver Power survey of over 30,000 car owners. Ratings are the average for all owners of this car who responded. Individual owners’ ratings and comments appear below.

A debutant in the 2014 Driver Power survey, despite being a 2008 model, Audi’s mid-size SUV shows conflicting qualities. It dropped 48 places in 2015 - from 44th to 92nd - largely because of very poor ride quality ratings from owners, who were also perplexed by the Q5’s high running costs. However, that’s all offset by fantastic build quality, strong performance and excellent practicality ratings – the first of those almost making the top ten.
