Which S6 years have the most problems?
Complaint volume by model year. Raw NHTSA totals, not adjusted for sales volume or time on the road, so older and higher-selling years accumulate more. Every year links to its full breakdown.
Sentiment is mixed and heavily dependent on the specific generation and powertrain. For the C7 generation (approximately 2013-2018) with the twin-turbo 4.0L V8 (4.0T), the vehicle is widely praised for its potent performance, refined luxury, and high-speed cru
Catastrophic turbocharger failure (C7 4.0T V8): Caused by restrictive oil screens leading to oil starvation, turbo failure, and potential engine destruction. Repair costs are extremely high ($9,000-$12,000 USD at a dealer). A manufacturer recall addressed the screen design. Frequency: very frequent.
Software and electronic issues (S6 e-tron): Numerous software glitches requiring multiple service visits, though not necessarily impacting drivability. Frequency: recurrent.
Carbon buildup (C6 V10 models): Leads to rough running and performance issues, particularly noted on 2007-2008 models. Frequency: recurrent.
Electric power steering rack failures: High failure rates reported on newer Audi models, leading to expensive repairs. Frequency: recurrent (mentioned in context of newer Audis, not S6-specific).
