Simply put, the A6 is a joy for both driver and passengers alike. Its potent supercharged V6 engine and slick eight-speed transmission deliver invigorating and effortless power. Available permanent Quattro all-wheel-drive assures traction and contributes to wintertime security. And yet at 22 mpg, fuel economy is quite commendable. But that's just the beginning.

Reliability indicates how models have performed in the past, providing the basis for predicting how the vehicles will hold up in the year ahead. These charts provide the most comprehensive reliability information available to consumers. Based on information received from our latest subscriber survey for over 300,000 vehicles, our reliability history charts give you a rundown on how 2000 through 2021 vehicles are holding up in 17 potential trouble spots, ranging from the engine, transmission, and brakes to power equipment and the electrical system. NA indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.
