Audi RS6 Buyers Guide

When the Fourth Generation Audi RS6 (C8, 2019–present) was introduced, it marked a bold return to the U.S. market, reigniting excitement among enthusiasts after a prolonged absence since the first-generation RS6. 

At its heart lies a twin-turbocharged 4.0-liter V8 engine paired with a 48-volt mild-hybrid system. This powerhouse delivers an impressive 591 hp and 590 lb-ft of torque, enabling the RS6 to rocket from 0 to 60 mph in just 3.5 seconds. Audi’s legendary Quattro all-wheel-drive system ensures this power is harnessed effectively, providing exceptional grip and control in all conditions.

The exterior design of the RS6 Avant has a wide, muscular stance accentuated by flared wheel arches that house massive 21-inch wheels (or optional 22-inch wheels). The front fascia features a bold single frame grille, matrix LED headlights with laser light technology and large air intakes. At the rear, it comes with a sculpted diffuser and dual oval exhaust outlets.

Inside, the RS6 Avant offers premium materials such as Valcona leather, carbon-fiber trim, and brushed aluminum. The fully digital MMI Touch Response system integrates two high-resolution touchscreens for intuitive control of the car’s infotainment and climate systems.

Audi’s Virtual Cockpit Plus provides a customizable digital gauge cluster, and optional RS-specific displays enhance the high-performance driving experience. The spacious interior also includes practical elements like generous cargo space and split-folding rear seats, making the RS6 uniquely versatile.

In its segment, the RS6 Avant competes with rivals such as the Mercedes-AMG E63 S, Porsche Panamera Turbo S Sport Turismo, and BMW M5. Despite the competition, the RS6 distinguishes itself with its iconic Avant body style, a perfect blend of family-friendly utility and uncompromising performance.

Audi RS6 Common Problems

While the fourth-generation Audi RS6 (C8, 2019–present) is celebrated for its outstanding performance, features, and practicality, like any high-performance vehicle, it is not without its challenges. Owners have reported a handful of recurring issues that, while not universal, are worth considering for prospective buyers. These concerns primarily revolve around electrical systems, mechanical components, and advanced features, which can sometimes lead to costly repairs if not addressed promptly. Below is a breakdown of the most common problems associated with the RS6.

Keep in mind, that it is essential that all cars, even supercars, can have issues and it is crucial to perform a Pre-Purchase Inspection (PPI) from an authorized dealer or experienced independent mechanic to reveal all issues.

Electrical System Malfunctions: Some owners have experienced warnings related to electrical system failures and sport differential malfunctions. These issues can cause multiple warning lights to illuminate on the dashboard, though the vehicle often continues to operate normally. In certain cases, the engine may shut down unexpectedly, requiring a restart to resume normal function.

Alternator Failures: There have been reports of alternator issues leading to battery charging problems and potential vehicle shutdowns. This problem has caused hesitation among potential buyers, as it can result in unexpected breakdowns.

Driver Assistance System Errors: Some RS6 owners have reported the loss of driver assistance functionalities, particularly during adverse weather conditions like heavy rain. These malfunctions can lead to the temporary unavailability of features such as adaptive cruise control and lane-keeping assist.

Turbocharger Concerns: The RS6’s twin-turbocharged engine is designed for high performance, but issues with the turbochargers have been noted. Problems can include reduced power output and unusual noises, potentially leading to costly repairs if not addressed promptly.

Suspension and Air Ride Problems: Owners have reported issues with the RS6’s suspension system, including premature wear of components and air suspension failures. These problems can result in a less comfortable ride and may require significant repair work.

Recalls

2021 Audi RS6 vehicles

Service brakes, hydraulic: Fluid (Recall no. 23V601000)

An incorrectly labeled brake fluid cap may have been installed, which can result in the use of the wrong type of brake fluid. Incorrect brake fluid can reduce braking ability and increase the risk of a crash.

2021 to 2022 Audi RS6 vehicles

Electrical system (Recall no. 22V861000)

Liquid spilled in the rear seat may penetrate and cause the gateway control module to shut down. A gateway control module shutdown will suddenly reduce engine power, increasing the risk of a crash.

2022 Audi RS6 vehicles

Back over prevention: Display function (Recall no. 22V806000)

The infotainment main unit may become damaged internally when the vehicle is shut off, resulting in an inoperative rearview camera display the next time the vehicle is started. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, “Rear Visibility.” An inoperative rearview camera display reduces the driver’s rear visibility, increasing the risk of a crash.

2021 Audi RS6 vehicles

Back over prevention: Display function (Recall no. 22V742000)

Due to a software issue, a blank or black screen may be displayed instead of the rearview camera image when the vehicle is placed in reverse gear. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, “Rear Visibility.” A blank rearview camera display can reduce the driver’s rear visibility, increasing the risk of a crash.

2021 to 2022 Audi RS6 vehicles

Electrical system: Instrument panel: Fuel gauge: Fuel level float/sensor/sending unit (Recall no. 22V155000)

The fuel level sender may stick, causing an inaccurate fuel level reading to be displayed on the instrument cluster. An inaccurate fuel reading may cause an engine stall due to lack of fuel, increasing the risk of a crash.

2021 Audi RS6 vehicles

Suspension: Rear: Axle: Non-powered axle assembly (Recall no. 22V034000)

The rear axle alignment may not have been inspected after the repairs for Recall 21V-295 (42L1) were performed. Rear axle misalignment may cause premature or uneven tire wear, increasing the risk of a crash.

2022 Audi RS6 vehicles

Back over prevention: sensing system: camera (Recall no. 21V825000)

A software error may prevent the rear-view image from initially displaying when the vehicle begins to reverse. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 111, “Rear Visibility.” A rear-view camera that does not display an image reduces the driver’s rear view, increasing the risk of a crash.

2021 Audi RS6 vehicles

Seat belts (Recall no. 21V606000)

The rear seat belt automatic locking retractors may deactivate early, which can prevent the child restraint system from securing properly. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 208, “Occupant Crash Protection.” An unsecured child restraint system can increase the risk of injury during a crash.

2021 Audi RS6 vehicles

Engine (Recall no. 21V339000)

Cracks may develop on the surface of the engine cylinder bore. Cracks may cause engine damage and a stall or an oil leak, increasing the risk of a crash or fire.

2021 Audi RS6 vehicles

Suspension: Rear: Axle: Non-powered axle assembly (Recall no. 21V295000)

The lock nut on the trailing arm of the rear axle may break due to stress corrosion. A broken lock nut may misalign the rear axle, causing a loss of control and increasing the risk of a crash.

2021 Audi RS6 vehicles

Air bags (Recall no. 21V159000)

The score line on the passenger air bag may not have been manufactured correctly. An incorrectly manufactured air bag may not deploy properly, and could also eject plastic debris into the passenger compartment, increasing the risk of injury during a crash.

2021 Audi RS6 vehicles

Electrical system (Recall no. 20V749000)

The electrical connector can detach from the door crash sensor in either of the front doors. A detached connector can delay the activation of the restraint systems, including the side air bag, curtain air bag and/or seat-belt pretensioners during a side impact crash, increasing the risk of injury.
