2016 Audi S6 Safety Report

The 2016 Audi S6 presents a mixed safety picture. While it boasts excellent crash test performance with a perfect 5-star overall rating from NHTSA, including 5 stars in Frontal, Side, and Rollover tests, its complaint data reveals significant powertrain reliability concerns. With only 19 total complaints, a relatively low number, a disproportionate 9 complaints (47%) are related to the ENGINE, often specifically citing turbocharger failures and associated engine stalls. This is directly addressed by NHTSA Recall 22V178000 concerning the turbocharger oil supply strainer, which can lead to engine stall and increased crash risk. Another recall, 18V310000, addresses a potential airbag sensor malfunction that could prevent proper front passenger airbag deployment, increasing injury risk. The most common complaint pattern revolves around catastrophic engine and turbocharger failures, frequently leading to sudden loss of power or engine stalls while driving. Several complaints describe the vehicle stalling on highways or in intersections, creating dangerous situations. These issues often occur at mileages ranging from 30,000 to 60,000 miles, well within the expected lifespan of a premium vehicle. Beyond the engine, there are isolated but severe complaints regarding brake system corrosion leading to fluid loss and braking failure, and transmission malfunctions causing jerking or intermittent power loss. The presence of a fire incident, though not detailed, adds another layer of concern. In summary, while the 2016 Audi S6 offers robust passive safety in a crash, its active safety and reliability are significantly undermined by critical engine and turbocharger issues, as evidenced by numerous complaints and a specific recall. Potential buyers should be aware of these known mechanical vulnerabilities, which can lead to dangerous driving conditions despite the vehicle's high crash test scores. The low overall complaint count might mask the severity of the recurring engine problems.

Our recommendation: Despite excellent crash test ratings, potential buyers of a 2016 Audi S6 should be highly cautious due to significant and recurring engine/turbocharger failures, which can lead to dangerous stalls; ensure all recalls are addressed and consider a pre-purchase inspection focusing on the engine and transmission.
