The Audi A4 remained highly competitive. In fact, this A4 was nearly everything a compact sports sedan should be. It has a solid, high-quality feel and the interior is exquisite. Agile handling makes it fun to drive and the ride, though quite firm, is supple and controlled. The cabin is quiet unless you ask the turbocharged four-cylinder engine to work hard.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2015 Audi A4 owners. The owner comments describe problems respondents experienced with this vehicle.

In-car Electronics

CD or DVD players, radio, speakers, GPS, communication system (e.g., OnStar), display screen freezes or goes blank, phone pairing (e.g. Bluetooth), voice control commands, steering wheel controls, portable music device interface (e.g., iPod/MP3 player), backup or other camera/sensors.

What Owners Say

External music device interface (e.g., smart phone, MP3 player)

"The car was sold to me with bluetooth which apparently does not mean bluetooth connection to music player (e.g., on ones phone) only blue tooth phone connection. This was only explained to me before I drove off. Clearly an attempt to upsell their obsolete navigation package, but the only thing they sold me on was buying another luxury brand next time. #NeverAgainAudi"

Aran A., MA (2015 Audi A4 2.0T 2.0-L 4 Cyl turbo)
In-dash navigation system (GPS)

"Not up to date"

Anonymous, AL (2015 Audi A4 2.0T 2.0-L 4 Cyl turbo)

"At times the Navigation system does not provide correct current location (shows me in a different part of the state), or is confused when providing directions. I have 're-booted' the system several times when the problem has occurred but it does not resolve the issue. After a day or so of driving, the Navigation system self corrects. In the meantime I used goggle maps from my phone, if I need directions."

Anonymous, NY (2015 Audi A4 2.0T 2.0-L 4 Cyl turbo)

"The system worked manually; however, it wasn’t able to process verbal commands accurately. Fixed by dealer under original warranty. Dealer was quite helpful in ameliorating the problem. gh"
