What Problems Does the 2021 Audi A6 Have?

While the 2021 Audi A6 is generally considered reliable, some frequently reported problems and concerns have surfaced. Some owners have reported issues with the infotainment system, including freezing, slow response times, and connectivity problems with Apple CarPlay and Android Auto. These issues can sometimes be resolved with software updates, but they can be persistent for some users.
There have also been reports of minor electrical glitches, such as issues with the sensors and driver-assistance features. These issues can range from false warnings to systems not functioning correctly. It's essential to check the functionality of all electronic features during a pre-purchase inspection.
Regarding recalls, it's crucial to check the NHTSA (National Highway Traffic Safety Administration) website for any open recalls on the specific vehicle identification number (VIN). While the 2021 model year might not have a significant number of recalls, it's always a good practice to verify.
Long-term reliability concerns often revolve around the complexity of the vehicle's systems. As with many modern luxury cars, the advanced technology can be prone to issues as the car ages. Regular maintenance, including fluid changes and inspections, is essential to mitigate potential problems. Some owners have also noted that the cost of repairing the advanced systems can be higher compared to more basic vehicles. Therefore, considering an extended warranty, especially for higher-mileage examples, could be beneficial.

How long will the 2021 Audi A6 last?

With proper maintenance, a 2021 Audi A6 can reasonably be expected to provide 150,000 to 200,000 miles or 10-12 years of service. Key to longevity is adhering to the recommended service schedule, including regular oil changes, fluid flushes, and inspection of wear items.
Long-term durability hinges on addressing potential weaknesses. As the car ages, the complex electronics might become more prone to failures. Suspension components and turbochargers may also require attention over time. Addressing these proactively can extend the A6's lifespan. Neglecting maintenance will significantly reduce its lifespan and increase the risk of costly repairs.

What Technology & Safety Features are Included?

The 2021 Audi A6 is packed with advanced tech, entertainment, driver-assistance, and safety features. Standard tech includes the Audi MMI infotainment system with an 8.8-inch display, Apple CarPlay, and Android Auto. Higher trims boast a 10.1-inch display with navigation and the Audi virtual cockpit, a fully digital instrument cluster. For entertainment, a Bang & Olufsen sound system is available.
Driver-assistance features are abundant, including Audi pre sense basic and city, which provide automatic emergency braking and pedestrian detection. Optional features include adaptive cruise assist, lane keep assist, blind-spot monitoring, and rear cross-traffic alert. These systems enhance safety and convenience on the road.
Safety features include standard airbags, anti-lock brakes, and stability control. Optional features like night vision assist further enhance safety.
As for crash-test ratings, the 2021 Audi A6 generally performs well in safety tests conducted by the IIHS (Insurance Institute for Highway Safety) and NHTSA. Check these organizations' websites for specific ratings and reports, as they provide comprehensive evaluations of vehicle safety performance. These features combine to make the 2021 Audi A6 a technologically advanced and safe vehicle.

2021 Audi A6 Prices and Market Value

When new, the 2021 Audi A6 had a starting MSRP of around $55,000, with higher trims reaching upwards of $75,000 depending on options. As of late 2024, used market prices typically range from $30,000 to $50,000, varying based on condition, mileage, and trim level.
The A6 depreciates at a moderate rate, influenced by factors such as mileage, condition, maintenance history, and trim. Lower mileage, well-maintained examples, and higher trims (like the Prestige) command higher resale values. Popularity of the Audi brand and overall market conditions also play a role in resale value.

2021 Audi A6 Cost of Ownership

Owning a 2021 Audi A6 involves moderate to high long-term costs. Insurance premiums are generally higher due to its luxury status and repair costs. Fuel costs depend on driving habits, but premium fuel is recommended. Maintenance, while not excessive if performed regularly, can be more expensive than non-luxury brands.

2021 Audi A6 Insurance

Insurance for a 2021 Audi A6 is moderately priced, reflecting its status as a Sedan with strong safety ratings and
reasonable repair costs.

How Does the 2021 Audi A6 Compare to Other Sedan?

The 2021 Audi A6 competes with the BMW 5 Series, Mercedes-Benz E-Class, and Volvo S90. In terms of performance, the A6 offers a balanced blend, similar to the E-Class but perhaps not as sporty as the 5 Series. Feature-wise, the A6 is competitive, offering a modern infotainment system and a range of driver-assistance technologies.
Reliability is a key consideration. The BMW 5 Series and Mercedes-Benz E-Class have similar reliability records, with potential for costly repairs as they age. The Volvo S90 is often regarded as a slightly more reliable option.
In terms of price, the A6 typically falls in line with its German rivals. However, the Volvo S90 can sometimes offer more value for the money.

  • BMW 5 Series: For a sportier driving experience.
