Is the 2019 Audi A6 reliable?

Owners rate it 4.89/5, a strong signal of long-term satisfaction.

The user feedback points to a dependable ownership experience, with owners describing the car as highly impressive overall and highlighting its luxury, performance, and advanced technology without notable complaints. The expert evaluation also emphasizes the A6’s refined drivetrain and the way its mild-hybrid system supports smoother, more efficient operation in everyday driving.

Audi’s light-electrified setup is designed to reduce engine load, shut the engine off earlier as you coast to a stop, and keep the car off longer in traffic, which supports a more relaxed ownership experience. For used buyers, the main long-term risk is less about the core concept and more about making sure the electronics, driver-assistance systems, and luxury features have been maintained properly.

What should I look for when buying a used 2019 Audi A6?

At 69.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.

You should start with a vehicle history report and then prioritize a thorough pre-purchase inspection, especially if the car has advanced driver-assistance equipment or larger wheels and performance tires. Focus on signs of prior bodywork, uneven panel gaps, tire wear, brake feel, and whether the cabin electronics and touchscreens operate cleanly and consistently.

Key things to evaluate:

• Trim level: Premium Plus is the best-value choice because it adds the features you’re most likely to want, including Audi Virtual Cockpit, a Bang & Olufsen audio system, a larger 10.1-inch navigation display, and a surround-view camera with Virtual 360 technology. Premium is the entry point, while Prestige brings the most upscale equipment and the most advanced available lighting and safety content.
• Powertrain: The A6 uses a turbocharged 3.0-liter V6 with 335 horsepower and 369 pound-feet of torque, paired with a 7-speed S tronic automated manual transmission and Quattro Ultra all-wheel drive. It also uses a 48-volt mild-hybrid system that helps with fuel-saving coasting and stop-start operation.
• Safety package: The Driver Assistance Package adds adaptive cruise control with traffic-jam assist and turn assist, active lane assist with emergency assist, intersection assistant, and traffic-sign recognition. Some of the more unusual and sophisticated systems are reserved for Premium Plus and Prestige trim levels.
• Infotainment: The cabin uses two touchscreen displays, Audi’s latest MMI system, a 10.1-inch navigation display, wireless-style smartphone-like interaction with haptic feedback, Google Earth imagery, handwriting recognition, and a surround-view camera with 360 Virtual View technology.
• Fuel efficiency: The expert test loop returned 22.9 mpg, while the EPA expectation cited was 25 mpg.

Which 2019 Audi A6 trim should I buy?

The 2019 Audi A6 is offered in 3 trim levels: Premium, Premium Plus, Prestige.

Here's the short version:

• Premium: This is the entry point, but the A6’s strongest appeal comes from its core luxury and technology package, so this trim makes sense if you want the redesigned sedan at the lowest starting price and are comfortable skipping some of the richer convenience and tech upgrades.
• Premium Plus: This is the best-value trim. It adds the features you’re most likely to appreciate every day, including Audi Virtual Cockpit, the larger navigation display, Bang & Olufsen audio, and the surround-view camera system.
• Prestige: Choose this if you want the most fully equipped version, especially if you value the most advanced lighting and the highest-end available safety and convenience content.

Audi notes that the more unusual and sophisticated driver-assistance systems are reserved for Premium Plus and Prestige trim levels.

What is the 2019 Audi A6's resale value?

That price movement suggests the market has already adjusted downward, which can help you buy with less risk of immediate overpaying.

Well-kept examples with desirable features should hold up better than neglected ones, especially in a luxury segment where buyers pay close attention to presentation and technology.

Vehicles with strong owner satisfaction ratings, like this model year's 4.89/5, tend to retain buyer demand, which supports resale value over time.

Should I buy a 2019 Audi A6 or consider a different year?

If you're weighing the 2019 against nearby model years, here's how to think about it:

Choose the 2019 if:

• 34.3% of listings are priced as good or great deals.
• At 69.2% accident-free, a meaningful share of listings has prior incidents — history verification is especially important.
• Price trend: Prices have softened 11.07% compared with last year.
• Owners rate it 4.89/5 — a strong satisfaction signal.
• The redesigned 2019 A6 brings a completely new MMI setup, a light-electrified hybrid powertrain, and more sophisticated driver-assistance technologies.

The bottom line: The 2019 A6 is the right pick if you want the redesigned model-year experience, strong tech, and a market that has already softened enough to create some negotiating room. If your priority is simply the lowest possible entry price, a nearby year may be worth comparing, but the 2019 stands out for its updated cabin, strong owner satisfaction, and broad feature content.
