What Problems Does the 2018 Audi A6 Have?
Frequently reported problems for the 2018 Audi A6 can include issues with the MMI infotainment system, such as glitches, freezing, or connectivity problems. Some owners have reported oil leaks, particularly in higher-mileage vehicles. Issues with the cooling system, like water pump failures, have also been noted. The adaptive cruise control system can occasionally malfunction, according to some reports.
Recalls for the 2018 A6 were issued related to potential fuel leaks due to faulty fuel rail sensors, which could increase the risk of fire. Other recalls may have addressed issues with airbags or other safety-related components. It's crucial to check the NHTSA website for the most up-to-date recall information.
Long-term reliability concerns generally revolve around the complexity of the vehicle's systems. Electronic components, turbochargers (especially in the 2.0T), and the multi-speed automatic transmission may require attention as the car ages. Regular maintenance, including timely oil changes and fluid flushes, is essential for mitigating potential problems. The supercharged V6 (3.0T) is generally considered more robust than the 2.0T, but both require vigilant care.

How Does the 2018 Audi A6 Compare to Other Sedan?
The 2018 Audi A6 competes with the BMW 5 Series, Mercedes-Benz E-Class, Lexus GS, and Volvo S90. In terms of performance, the A6 offers a balance, but the BMW 5 Series often edges it out in sporty handling. The Mercedes-Benz E-Class provides a more luxurious ride. Regarding features, the A6 is well-equipped, but the E-Class and 5 Series may offer more advanced technology options.
Reliability is a mixed bag. Lexus GS is known for its superior reliability.
