2017 Audi A6

There is an issue with the power steering control module that causes a lot of error codes to populate. Many of the codes are generic and hard to diagnose, even with Audi certified diagnostic equipment/tools. When this code initially presented, ~9 months ago, there was a red steering wheel light on the dash. I found a company that repairs these modules with these specific codes (I’d imagine good business since this is a common issue); while I got power steering to work, there are codes that still recommend full replacement of the power steering module (Audi certified diagnostic equipment). This error in the module causes complete loss of power steering, with serious risk to safety of all passengers and other drivers, on and off the road. Because this module may communicate with other modules and systems, it may render other codes and faults with the abs and start/stop systems for example. I’ve taken this issue to an Audi dealer and they say I have to pay out of pocket for a whole replacement of the module and rack&pinion. I understand how to maintain a vehicle but this is a known issue for many other models/trims and years. I’ve read some reports that Audi had de-escalated this issue in other models (2012-2016) to avoid a larger number of vehicles being affected. While my vehicle is 2017, it’s out of the “covered recall” but I’m experiencing similar issues to the very same issue. PS. My car has been sitting for 9 months due to this issue.

The steering rack for my 2017 Audi A6 2.0T Premium Plus Quattro has failed at roughly 54000 miles. This is the same exact OEM part (OEM Part # 4G1423055EA) that is used in the 2016 A6, which has an extended warranty from Audi due to a lawsuit of 10 years and 125000 miles. My VIN is not included in this extended warranty even though the 2017 Audi A6 and 2016 Audi A6 are the same engines, use the same OEM steering rack parts, and are the same vehicle outside of minor exterior updates in the facelift model (2017). This part has failed and now I'm being charged $6323.77 by the Audi dealership to fix this issue. I am sure this is simply the same issue as it is the same exact part in the same engine. This extended warranty must include all future Audi vehicles that use the same steering rack that is problematic and was given an extended warranty to cover the replacement.

While driving my family on a major Interstate, a myriad of warning ⚠️ lights appeared on my dash panel and my vehicle’s steering literally locked! I have had no previous warning lights or issues with this vehicle since it was purchased. This near fatal incident happened as a 18-wheeler was seeking to merge onto the Interstate and I couldn’t change lanes to allow the oncoming traffic to merge. This malfunction/failure caused me and my family to narrowly miss being fatally crushed by the merging 18-wheeler. After bringing the vehicle to a stop in a safe area off of the Interstate and locating the vehicle owner’s manual, I learned that the Electromechanical Steering Unit failed on my 2017 AUDI A6 (Mfg 6/16). Because all of the local AUDI dealerships were closed, I had to call and have the vehicle towed to my home. Upon further researching the issue in various AUDI forums, I realized this system failure was widely experienced by AUDI owners and that it may have even played a part in prompting AUDI to issue “Electromechanical Steering Unit Extended Warranty” letters to certain AUDI 2011-2016 vehicle owners (A6 owners included). I believe NHTSA should do its due diligence in seeking to reduce highway safety fatalities on our nations highways caused by vehicle safety defects/malfunctions by auto manufacturers and execute a mandate for AUDI to (1) issue a SAFETY RECALL for this issue, OR (2) extend the Electromechanical Steering Unit Warranty to include later model year vehicles. It appears that AUDI has not corrected the known issue on their own; thereby warranting NHTSAs regulatory intervention. I would like NHTSA to launch a defects/safety investigation to determine how many more AUDI owners are at risk of experiencing this life-threatening, correctable, and known issue. Please keep me informed on the results of my report.

My 2017 Audi A6 has approximately 50,000 miles on it. I am diligent about obtaining regular maintenance on my vehicle and visited the Audi dealership in Memphis, TN for a 50,000 mile inspection and service in June of 2021. Last week, just 3 months after my 50,000 mile services/inspection, my vehicle stopped operating correctly when making a turn from stopped at a stop sign and lost all power steering. I was informed by the Audi dealership in North Miami, FL (where I am now located), that the steering rack on the vehicle is faulty. The vehicle and this component are still located at the Audi dealership in North Miami while they wait for the part to come in. I can coordinate to make it available for inspection if you would like. I am concerned that this part failed after only 50,000 miles and am particularly concerned that this poses a major safety issue. I was lucky that I was at a near stop and able to make it to safety when this component failed. Had the power steering gone out at any other time, for example, while I was in the middle of an intersection or while driving on a busy roadway, it could have resulted in a major incident. I did not have any warning signs that the power steering was about to shut down, and as mentioned, I had the vehicle inspected just 3 months earlier without any issues. It is also worth noting that Audi had a known issue with the steering rack in the 2012-2016 model years for my vehicle and offered to reimburse owners of those vehicles and warranty the steering rack to 125,000 miles. Audi has indicated to me that the steering rack in my vehicle is the same part as that used in 2016.
