an unusual number of complaints, unusually dangerous
ones, or failures that arrived unusually early.
The dashed ring is 50 — the national norm. Further out is worse.
Complaint volume — 43
Against the median year of the Audi S6. 50 means typical for this
model; 100 means roughly double.
Severity — 34
6.7% of these complaints
involved a crash, fire, injury or death, against a national rate of
9.7%.

A spike years after the car went on sale usually means a part wearing

NHTSA investigations into the 2016 Audi S6
An investigation is the step before a recall: the agency has seen enough
complaints to look into a pattern itself. An open one means it thinks
something may be wrong and nothing has been fixed yet.

Recalls on the 2016 Audi S6
A complaint is one owner's allegation. A recall is the point at which
the manufacturer or a regulator agreed the defect is real and dangerous
enough to fix for free — however old the car is.
Canada — Transport Canada
Canada runs its own recall programme, and its campaigns do not
always mirror the American ones.
Recall 20221332,548 units in Canada
Engine
Issue: On certain vehicles, the oil strainer for the turbocharger oil supply could get blocked. If this happens, a turbocharger could fail. This could cause loss of engine power and/or cause the engine to stall. Note: This problem could cause different warning messages to display or the engine oil warning light to turn on. Safety Risk: A sudden loss of engine power could increase the risk of a crash. Corrective Actions: Audi will notify owners by mail and instruct you to take your vehicle to a dealership to replace the oil strainer for the turbocharger oil supply. The dealer will also inspect and document the performance of the boost pressure system and change the engine oil.
Recall 20183652,672 units in Canada
Airbag
On certain vehicles, a problem with the passenger occupant detection system can cause illumination of the airbag warning light and the airbag system may not properly classify the front passenger. In the event of a crash, the airbag system may not function properly, increasing the risk of injury to a front passenger. Correction: Dealers will install a passenger occupant detection system repair kit.

SERVICE BRAKES
The front passenger-side 6-piston Brembo caliper's (Part No. 20.A989.63) external steel crossover tube failed due to corrosion, specifically where the tubing was covered by a protective rubber sleeve, which trapped moisture and road salt. This led to a catastrophic loss of brake fluid and braking capability. This appears to be a systemic corrosion defect.

SUSPENSION
Subject: Formal Complaint Regarding Defective Arnott Front Air Strut To Whom It May Concern, I am writing to formally report a significant safety concern regarding a defective Arnott FL front air strut purchased via RockAuto for my 2016 Audi S6 (VIN: [XXX] ). The air strut failed within five days of professional installation. This failure compromised the safety and functionality of my vehicle's suspension system, potentially risking further damage and endangering passengers. I was forced to drive the vehicle briefly in this compromised state to arrange for reinstallation, creating an additional safety hazard. Details of the issue: Product: Arnott FL Front Air Strut (purchased via RockAuto). Professional Installation Dates: October 25, 2024, and reinstallation due to failure on November 27, 2024. Failure Description: The air strut lost functionality within five days of installation, causing a significant drop in vehicle height and inability to maintain proper suspension. This defect demonstrates a failure of Arnott’s quality control and has left me concerned about the safety of their products, particularly when they play a critical role in vehicle performance and passenger safety. I am requesting that NHTSA investigate this matter to ensure no systemic issues with Arnott's products compromise the safety of other drivers. I have attached supporting documentation, including invoices for installation, reinstallation, and further details on the defective part. Thank you for your attention to this urgent safety matter. I look forward to your acknowledgment and any updates regarding this investigation. Sincerely, [XXX] [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

POWER TRAIN
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.

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.

STEERING
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.

The contact received notification of NHTSA Campaign Number: 22V178000 (Engine and Engine Cooling) however, the repair had been previously completed by an independent mechanic, a year prior to receiving the recall letter. The contact filed paperwork to be reimbursed after receiving the recall letter. The contact had taken the vehicle to a dealer, and the dealer stated that the vehicle was no longer under warranty. The dealer had not performed the recall repair, stating that the vehicle had been modified. The manufacturer was made aware of the issue. Parts distribution disconnect.

I was driving my car and it stalled out in the middle of an intersection which was totally unsafe and it would barely start. I was able to limp it to safety but it would not run or idle correctly. I had it towed to the local Audi dealership and they diagnosed the issue as being the turbos. The turbos failed and need to be replaced. The obvious known issue with the oil screen starving the turbos and causing collateral damage is well documented hence Audi issued an extended warranty on turbos and the recall on the oil screen however the dealer is refusing to do any repair and has had the vehicle for over a week.

The Passenger Side Turbo failed. Yes it’s available for inspection. I was driving and I felt a pop, like a backfire from under the hood. The car lost power instantly and was any under power anymore on the road. It could have been a lot worse if I was on a busy highway but luckily was on a street with do one behind me. It was confirmed it was the turbo failure and the turbo has been inspected. No warning lamps or any prior symptoms before hand. Once it happened it started throwing warning lights for pretty much everything. Limited slip diff, air bags, EPC, TPMS, check engine light and traction control warning lights all went off one after the other.

THE CAR HAD TO BE TOWED TO A REPAIR SHOP. IT WAS LATER DETERMINED THE TURBOS HAD FAILED DUE TO A LOSS OF OIL SUPPLY. THE OIL SUPPLY IS CUT OFF DUE TO THE SINGULAR TURBO OIL SCREEN BEING CLOGGED. REGULAR OIL CHANGES ARE DOCUMENTED AT CORRECT INTERVALS. AUDI AFTER THE MIDDLE OF MY2016 INSTALLED A REVISED TURBO OIL SCREEN TO HELP PREVENT THIS FROM HAPPENING. IT IS A KNOWN FAULT AT AUDI AND SHOULD ABSOLUTELY BE A RECALL TO REPLACE THE OIL SCREENS WITH THE REVISED VERSIONS. IT IS A MAJOR SAFETY ISSUE WHEN THE ENGINE CAN SUDDENLY STOP RUNNING AT ANY SPEED.

BOTH MY TURBOS FAILED ON MY CAR ON CHRISTMAS DAY IN 2019. I WAS COMING HOME FROM DROPPING OFF MY DAUGHTER 90 MINUTES AWAY. AFTER LEAVING THE HIGHWAY AND STARTING TO MOVE ONCE THE LIGHT TURNED GREEN, MY CAR DECIDED TO COMPLETELY STALL. I WAS ABLE TO PULL OVER THE TO SHOULDER AS I WAS COMING TO A STOP AS I WAS ON A ONE LANE ROAD. MY CAR WAS TOWED AND IT WAS DETERMINED THAT MY CAR HAD BOTH TURBOS FAIL. I RECEIVED MY CAR BACK A MONTH LATER AND SINCE THEN HAVE HAD A COOLANT LOSS ISSUE AS WELL AS A SURGE ISSUE. THE COOLANT LOSS ISSUE REQUIRES ME TO PUT 4 OUNCE OF COOLANT INTO MY CAR EVERY MORNING. I REPORTED THIS ISSUE TO MY AUDI DEALERSHIP WHEN I GOT MY CAR BACK BUT IT HASN'T BEEN FIXED. I'M UNSURE IF THE COOLANT ISSUE IS WHAT CAUSED THE TURBOS TO FAIL, OR PARTS OF MY TURBOS PROPELLERS WENT INTO MY ENGINE OR SOMEPLACE ELSE WHICH IS CAUSING ISSUES WITH THE CAR. FURTHERMORE, THE CAR NOW SURGES WHEN COMING TO A STOP. THE CAR WILL SURGE A FOOT OR TWO AFTER IT'S COME TO A COMPLETE STOP WHICH IS DANGEROUS.
