NHTSA lists 2 safety recalls and 19 owner complaints for the 2016 Audi S6. Most complaints involve engine (13) and power train (3). The EPA rates it 21 mpg combined, and NHTSA gives it 5 stars overall.
Volkswagen Group of America, Inc. (Audi) is recalling certain 2013-2017 A8, S6 Sedan, S7, S8, and 2014-2017 RS7 vehicles. The turbocharger oil supply strainer can become blocked, causing wear to the bearings due to lack of lubrication.
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2013-2018 Audi S6 and S7, 2012-2018 A7 and A6 Sedan, and 2014-2018 RS7 vehicles equipped with basic seats (with or without heating). Stress or wear of the body-sensing mat within the front passenger seat may cause the Passenger Occupant Detection System (PODS) control module to malfunction.
Complaints are unverified owner reports to NHTSA and are not normalized for sales volume. One complaint can cite several components.
“Hi - The Crankcase Ventilation Valve Extended Warranty [XXX] covers only ten years or 120k miles. My car has close to 160k miles. According to NHTSA or Audi, “Audi has determined that, in some vehicles, it is possible for the crankcase ventilation valve to malfunction, causing a whistling noise in the engine compartment and the MIL to illuminate due to the presence of specific fault codes caused by this component. This condition may impact the vehicle tailpipe emissions, and the presence of a MIL-on condition may cause the vehicle to fail an IM (smog) test.” This is causing the engine to rev on its own, foul odor, consume more oil and gas, MIL-on, and potentially cause the IM (smog) test to fail regardless of years or miles and a safety issue. Please add this matter to recall rather than extended warranty and is likely related to NHTSA Campaign Number: 22V178000 which is causing oil separator and coolant pipe issues that need to be covered. [XXX]”
“We, a group of Audi S6 owners with vehicles from the 2013-2017 model years, are experiencing premature mechatronic issues. These problems manifest as jerking when coming to a stop, which can lead to accidents, and intermittent power loss that can be life-threatening. These issues began around 40,000 miles and have progressively worsened, despite our vehicles having only approximately 70,000 miles on them. Given the early onset and severity of these problems, we strongly urge a recall. The current mechatronic design appears to be flawed and fails prematurely, posing significant safety risks.”
“While driving with my wife and kids, on the highway, in the rain a warning message was displayed. The warning stated: steering malfunction, please stop the vehicle!. At which point the power steering locked-up & the engine powered down. As a result, I was unable to steer the vehicle. Thankfully, I was able to “muscle” the car off the highway and onto a secondary roadway. Vehicle was towed. With the power steering locking-up and not being able to effectively steer the vehicle this is a HUGE safety issue and needs to be addressed with Audi. This could have ended tragically if it were to happen to a driver who was unable to “muscle” the vehicle to safety.”
Towing, payload and dimensions aren’t in the EPA or NHTSA data, so we don’t list them.
