5/5 Overall
NHTSA 5-Star Safety Rating
The dominant complaint pattern for the 2017 Audi A6 centers on airbags and engine-related issues, with steering rounding out the most-reported systems. On the engine side, owners frequently describe hydraulic motor mounts failing and leaking fluid, sometimes repeatedly, leaving the engine sitting in a metal-on-metal condition. Complaints also mention timing chain cover leaks, manifold leaks, and water pump failure, often on vehicles under 75,000 miles. Airbag system complaints make up the largest single category, though the narratives don't point to one uniform symptom across those reports. Steering complaints describe two distinct issues: a power steering control module generating difficult-to-diagnose error codes accompanied by a warning light, and steering rack failure at relatively low mileage. A smaller number of reports mention the blind-spot monitoring system intermittently failing to detect vehicles, including large trucks, without storing diagnostic codes.

Total Complaints
By System
The 2017 Audi A6 has 3 recalls, the most serious being leaking fuel rails that can allow fuel to escape near an ignition source and start a fire.
Two recalls involve airbag and restraint systems. On vehicles equipped with basic front passenger seats, the seat's body-sensing mat can wear or degrade over time, causing the passenger occupant detection system to malfunction and the front passenger airbag to fail to deploy in a crash. A separate recall covers a broader restraint system concern where the driver frontal airbag, passenger frontal airbag, or head airbags may not deploy correctly, and the seatbelt pretensioners may not tighten as intended, both of which raise the risk of injury in a collision.
