Overview

2021 Audi RS 6 Avant

The 2021 Audi RS 6 Avant is a high-performance station wagon that blends supercar-like acceleration with everyday practicality. Its twin-turbocharged V8 engine delivers formidable power, channeled through Audi's renowned Quattro all-wheel-drive system. However, prospective buyers should be aware of its 'Average' reliability verdict. A high number of recalls, particularly concerning safety-critical systems like airbags and seat belts, alongside a substantial count of Technical Service Bulletins (TSBs), suggest potential ownership complexities and the possibility of significant repair costs if issues arise. The absence of consumer complaints is noted, but this does not negate the need for diligent pre-purchase inspection.

Critical Failure Risk

A critical recall involves a potential cracked cylinder bore in the 4.0L V8 engine. This manufacturing defect can lead to significant engine damage and failure, necessitating a full engine replacement.

Early detection can help you avoid a repair of about $10,000.
