Engine complaints dominate what 2013 Audi S6 owners report, with oil leaks from the lower crankcase area being the most commonly described symptom. Multiple owners describe oil seeping where the crankcase meets the engine block, often requiring significant repair work. A secondary cluster of complaints involves the transmission and drivetrain: owners report the vehicle refusing to engage reverse, getting stuck in first gear, skipping gears, and overheating warnings appearing on the dash. Several reports describe the car abruptly dropping speed on the highway, from freeway speeds down to roughly 20 mph, accompanied by multiple warning lights appearing simultaneously, including engine, suspension, and electronic power control indicators. Power steering loss during these episodes also comes up across multiple reports. The pattern of sudden power loss paired with a cascade of dashboard warnings is the most consistent thread running through the complaint set.

By System
The 2013 Audi S6 has 4 recalls, the most serious being a fuel line that can leak and, near an ignition source, cause a fire.
The fuel line concern covers the 4.0L engine and can develop either from manufacturing tolerances or gradual damage over time; both point to the same real-world risk of a fuel-fed fire. On the engine side, the turbocharger's oil supply strainer can become blocked, starving the bearings of lubrication. As the bearings wear, the turbine wheel can contact the turbocharger housing or the shaft can break, either of which can stall the engine while driving. There is also a safety equipment concern: the passenger seat's body-sensing mat can wear or stress over time, causing the occupant detection system to malfunction and potentially preventing the front passenger airbag from deploying properly in a crash.
