The redesigned Audi A6 is among the best midsized luxury sedans we've tested. It has class-leading fuel economy, lively and sporty handling, an easy-to-use infotainment system, and an elegant, if understated, interior. However, the Audi's low-speed manners and its ride, which is on the firm side, prevent it from taking top honors in the class.

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.

Owner Reported Trouble Spots

The Reliability score is based on our latest subscriber survey of 2019 Audi A6 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

Apple CarPlay

"difficult to understand the instructions and inconsistent"

Anonymous, MA (2019 Audi A6 3.0T 3.0-L V6 turbo)

"CarPlay functionality has been intermittent. For 6 month trial period of Audi connect carplay worked nearly all the time. After 6 month trial expired and I renewed Audi Connect Premium, CarPlay is only functional about half the time. I consider it a safety hazard, because it will sometimes just stop working after I’ve started a drive using Apple maps or Waze for directions. Then I am scrambling to try to get nav to work. It also will stop allowing me to make hands free calls."

Anonymous, GA (2019 Audi A6 3.0T 3.0-L V6 turbo)

"My 'link' to my iPhone becomes 'broken' and I have to do a reset. I can easily get CarPlay back by physically plugging my phone in, but prefer not to have to do this. The dealer 'fixed' the problem, but it has reoccurred."

Anonymous, ME (2019 Audi A6 3.0-L V6 turbo)
Backup or other camera/sensors

"The backup camera failed to start on two occasions. It has not been reported to Audi."

Anonymous, NY (2019 Audi A6 3.0-L V6 turbo)

"Occasionally, the back-up camera remains 'blank' (no image). Sometimes, it will reset itself if I restart the car."

Anonymous, ME (2019 Audi A6 3.0-L V6 turbo)
Display screen goes blank

"On a few occasions the multi media MMI screen had resolution issues that interfered with the ability to use it. These ranged in severity from slight to complete. Audi was unable to find a cause; however the problem has happened less than four times."

Anonymous, NY (2019 Audi A6 3.0-L V6 turbo)

"The entire interface locks up periodically. I have to pull the car over, turn the car off, then restart to reboot the system. Sometimes this fixes it. I have brought it into the Audi dealership several times and they have not been able to figure out the problem."

Anonymous, FL (2019 Audi A6 2.0-L 4 Cyl turbo)
Phone pairing (e.g., Bluetooth)

"Phone pairing has become an intermittent problem."

Anonymous, GA (2019 Audi A6 3.0T 3.0-L V6 turbo)
Software update fixes

"MMI is awful, terribly distracting, takes minutes to boot up, dealer says nothing is wrong"

Anonymous, MA (2019 Audi A6 3.0T 3.0-L V6 turbo)

Drive System

Driveshaft or axle, CV joint, differential, transfer case, 4WD/AWD components, driveline vibration, traction control, electronic stability control (ESC), electrical failure.

What Owners Say

Electrical failure

"The DC to DC converter that changes the 48 volt system to the 12 volt system failed resulting in a complete failure of the car. It could not be started. Absolutely nothing worked except for the headlights that were stuck ON. The car doors were unlocked when the car failed. The front wheels were locked due to the electrical failure (car locked in PARK) and the car had to be dragged to get it on to a flat bed tow truck. The car was in the shop for over a week to be fixed. It had about 300 miles on it when it totally failed. A call to Audi Roadside Assistance was useless as they did not know what to do and never came back to tow the car. I finally called AAA who showed up within 12 minutes."

Michael F., MA (2019 Audi A6 3.0T 3.0-L V6 turbo)

"A voltage converter for the 48 volt to 12 volt system failed making the car undrivable. It had to be towed to the dealer. Took two weeks to be fixed. Failure of the system that controls rear lighting, i.e. brake lights, tail lights, backup light, etc. The car was drivable but dangerous since it had no brake light indication."

Anonymous, (2019 Audi A6 3.0-L V6 turbo)

Body Integrity

Squeaks, rattles, wind noises, loose or cracked seals and/or weather-stripping, air and water leaks.

What Owners Say

Squeaks or rattles

"Slight rattle in drivers door when going over certain types of bumps in the road."

Raymond V., IL (2019 Audi A6 3.0T 3.0-L V6 turbo)

"Sunroof rattle. Fixed once by the dealer. Problem returns sporadically. Have brought it back to the dealer, but during test drive rattle could not be heard. Car would be perfect otherwise."

Anonymous, NY (2019 Audi A6 3.0-L V6 turbo)

Electric System

Alternator, starter, hybrid battery and related systems, regular battery, battery cables, engine harness, coil, ignition switch, electronic ignition, distributor or rotor failure, spark plugs and wires failure.

What Owners Say

Remote engine starter

"There is a problem with the ignition system that has now led to a recall as several veshicles have caught fire during wet weather. They don't have a fix yet but said we would hear from them in "a few weeks.""

Cruise control, clock, warning lights, body control module, keyless entry, wiper motor or washer, tire pressure monitor, interior or exterior lights, horn, gauges, 12V power plug, remote engine start, alarm or security system

What Owners Say

"When the electrical system failed, the headlights seemed to be stuck on draining the battery. I have requested a replacement as it is not good for the car battery to be fully drained."

Michael F., MA (2019 Audi A6 3.0T 3.0-L V6 turbo)

Fuel System

Check engine light, sensors (includes O2 or oxygen sensor), emission control devices (includes EGR), engine computer, engine computer, fuel cap, fuel gauge/sender, fuel injection system, fuel pump, fuel leaks, stalling or hesitation.

What Owners Say

Fuel injection system

"The car had slightly more than 1000 miles when it suddenly began bucking and the engine warning light came on. After I parked and turned off the engine, I was unable to start the car again. Audi picked up the car and gave us a loaner. It took slightly more than 1 week to get our car repaired and returned."
