2021 Audi Rs6 problems
The Audi RS 6 is a high-performance variant of the Audi A6 range, produced by the high-performance subsidiary company Audi Sport GmbH, for its parent company Audi AG, a subsidiary of the Volkswagen Group, from 2002 onwards.
The first and second versions of the RS 6 were offered in both Avant and saloon forms. The third and fourth generations are only offered as an Avant.
Overview
The "RS" initials are taken from the German: RennSport – literally translated as "racing sport", and is Audi's ultimate 'top-tier' high-performance trim level, positioned a noticeable step above the "S" model specification level of Audi's regular model range line-up. Like all Audi "RS" models, the RS 6 pioneers some of Audi's newest and most advanced engineering and technology, and so could be described as a halo vehicle, with the latest RS 6 Performance having the equal most powerful internal combustion engine out of all Audi models, with the same horsepower and torque as the physically larger Audi S8 Plus. Unlike the A6 and S6, however, the RS 6's engines in the C5 and C6 iterations have not been shared with any other vehicle in Audi's lineup. However, for the C7 generation, the Audi RS 6 has the same 4.0L bi-turbo V8 engine as the Audi RS 7, with both being positioned at the top of the Audi S and RS range, and detuned variants of the same engines are found in the Audi S8, Audi A8, and Audi S6.
Based on the A6 platform, the RS 6's engines are front-mounted and longitudinally oriented, while the transmission is mounted immediately at the rear of the engine in a longitudinal orientation, in the form of a transaxle. Like all S and RS models, the RS 6 is only available with Audi's 'trademark' Torsen-based quattro permanent four-wheel drive system.
The C5 RS 6 was the fourth model to come out of Audi's private subsidiary company, "quattro GmbH". The first was the Audi RS 2 Avant, from a joint venture between Porsche and Quattro GmbH for the Audi marque. The second was the Audi C4 S6 Plus, produced from April 1996 to July 1997. The third was the 2000 Audi B5 RS 4; the fifth was the 2005 Audi B7 A4 DTM Edition saloon, and the sixth was the 2006 Audi B7 RS 4. The seventh and current (as of January 2010) Quattro GmbH model is the latest Audi C6 RS 6.
Production of the original Audi C5 RS 6 began in June 2002 and ended in September 2004. The second Audi C6 RS 6 was introduced at the 2007 Frankfurt Motor Show. The original RS 6 (C5) was the first Audi RS variant exported to North America, while the C6 and C7 RS 6 were only sold in Europe, with the C8 RS 6 again being offering in North America.
Main rivals for the Audi RS 6 are the BMW M5 and Mercedes-Benz E 55/E 63 AMG.

Common 2021 Audi Rs6 problems
The 2021 Audi RS6 has been reported to have several common problems based on complaints from its owners. These issues range from recalls to specific problems with the car's features and components.
One of the most common problems is related to the electrical system, specifically the fuel gauge. Volkswagen Group of America, Inc. (Audi) has issued a recall for certain 2021 Audi RS6 Avant, RS7, 2020-2021 A6 Allroad, S6 Sedan, S7, 2019-2021 A6 Sedan, and A7 vehicles due to a potential issue with the fuel level sender. The fuel level sender may stick, causing an inaccurate fuel level reading to be displayed on the instrument cluster. This issue can lead to problems with fuel management and potentially leave drivers stranded with an empty tank.
Another common problem is related to the suspension system. Audi has issued a recall for certain 2019-2021 Audi A5 Sportback, RS5 Coupe, RS5 Sportback, S5 Sportback, 2020-2021 A4 Allroad, A4 Sedan, A5 Cabriolet, A5 Coupe, A6 Allroad, A6 Sedan, A7, A8, Q5, S4 Sedan, S5 Coupe, S5 Cabriolet, S6 Sedan, S7, S8, SQ5, 2021 Q5 Sportback, Q7, Q8, RS6 Avant, RS7, RS Q8, SQ5 Sportback, SQ7, and SQ8 vehicles due to a potential issue with the rear axle alignment. The rear axle alignment may not have been inspected after the repairs for Recall 21V-295 (42L1) were performed, which can lead to premature or uneven tire wear.
Additionally, there have been reports of the lock nut on the trailing arm of the rear axle breaking due to stress corrosion. This issue can lead to a loss of control and potential accidents. Audi has issued a recall for certain 2021 Q7, Q8, Q5 Sportback, SQ5 Sportback, RS6 Avant, RS7, RS Q8, 2020-2021 Audi S6 sedan, Q5, A8, S8, A7, A6 Allroad, A5 Cabriolet, A4 sedan, A4 Allroad, SQ5, S7, A6 sedan, S5 coupe, S4 sedan, S5 Cabriolet, A5 coupe, 2019-2021 RS5 coupe, A5 Sportback, S5 Sportback, RS5 Sportback vehicles to address this issue.

The score line on the passenger air bag may not have been manufactured correctly, which can lead to the air bag not deploying properly in the event of a crash.
Another common problem reported by owners of the 2021 Audi RS6 is related to the HVAC controls. The touchscreen controls for the HVAC system have been criticized for being both daft and dangerous, as they require drivers to take their eyes off the road to adjust the cabin temperature
There have also been reports of suspension issues, with the front of the car dropping 24 hours after sitting to zero fender/tire gap, indicating a suspension issue. Additionally, there have been reports of alternator failure after two years/25,000 miles, which can lead to the car dying and draining both the 12 and 48-volt batteries.
In summary, the 2021 Audi RS6 has several common problems that have been reported by its owners. These issues range from recalls related to the electrical system, suspension, and airbags, to specific problems with the HVAC controls and alternator. It is important for owners of this vehicle to be aware of these issues and to address them promptly to ensure the safe and reliable operation of their vehicle.
How reliable is Audi RS6?
Still, the RS6 Avant is based on Audi's regular A6 model, which we've heard no horror stories about, and because it uses a lot of proven tech from across the range, the RS6 shouldn't be unreliable.
