5/5 Overall
NHTSA 5-Star Safety Rating
For the 2016 Audi A6, the heaviest complaint volume centers on engine and fuel system issues. Owners most frequently describe unexpected stalling, sometimes at highway speeds, along with EPC warning lights and fuel rail-related fault codes. Coolant system failures come up repeatedly, with several owners reporting premature water pump failures, in some cases multiple times on the same vehicle. On the fuel side, owners describe a sudden and dramatic drop in indicated range after a full fill-up, without any accompanying warning lights or obvious leaks. Airbag complaints make up the second-largest named category, though the specifics across those reports vary. An isolated report describes an under-hood fire with the ignition off. The stalling pattern is the most consistent thread, with owners describing the engine cutting out without warning during normal driving.

By System
The 2016 Audi A6 has 3 recalls, the most serious being two separate fire risks: an auxiliary heater electrical connector that can overheat and ignite, and fuel rails on both sides of the engine that can leak fuel near potential ignition sources.
The third recall involves the front passenger seat's occupant detection system. A sensing mat built into the seat cushion can wear or develop stress damage over time, causing the detection module to misread or stop working. When that happens, the front passenger airbag may not deploy correctly in a crash, leaving the occupant without full restraint protection.
