2012 Audi Q7

The Office of Defects Investgation (ODI) opened EA11-003 on February 7, 2011, based on 160 complaints to ODI and Volkswagen involving high pressure fuel pump (HPFP) failures in model year (MY) 2009 through 2010 Volkswagen Jetta and Golf and Audi A3 TDI vehicles and questions regarding fuel sample results provided by Volkswagen as part of its response to PE10-034.During EA11-003, ODI analyzed design information, field experience and test data for MY 2009 through 2012 Volkswagen Jetta, Golf and Touareg and Audi A3 and Q7 vehicles equipped with TDI engines. Volkswagen has not identified any design or manufacturing defects in the subject TDI Clean Diesel pumps and has stated that the subject pumps were designed, tested and approved for use in the United States market, with substantial design margins for fuels that are out of specification.Volkswagen believes that misfueling with gasoline is the primary cause of HPFP drivetrain failures in the field.Only the Q7 vehicles were built with misfuel protection devices.In May 2013 Volkswagen initiated a service campaign to install misfuel protection devices in all MY 2009 through 2012 Jetta, Golf and A3 vehicles.Volkswagen implemented misfuel protection devices in all of the subject models beginning in MY 2013. ODI?s analysis of HPFP drivetrain failure incidents indicates that most failures do not result in engine stall while driving and, when pump drivetrain failure does result in stall while driving, it is usually preceded by numerous warning symptoms (e.g., glow plug warning lamp, chime, limp mode, and driveability symptoms).The failure data for the subject vehicles show relatively low stalling rates (less than one percent at three years in service) for each of the pump designs used in the subject vehicles.There have been no reports of crashes, injuries or fatalities related to the alleged defect. Based on these facts, this investigation is closed.The closing of this investigation does not constitute a finding by NHTSA that a safety-related defect does not exist.The agency will continue to monitor complaints and other information relating to the alleged defect in the subject vehicles and take further action in the future if warranted.For additional information, see the closing report in the document file for EA11-003.

On or December 5th, 2025 (4 days after taking possession of the vehicle, I experienced a sudden and severe steering system failure while driving. When turning the steering wheel (even slightly), the vehicle produced a loud buzzing/grinding noise and the steering effort increased significantly, creating an immediate safety hazard. Because the steering issue worsened quickly and made the vehicle difficult to control, I stopped driving and brought the vehicle to an authorized Audi dealership for inspection. The Audi dealership confirmed the steering failure was caused by a major power steering system defect, including active power steering fluid leakage from the steering rack area consistent with internal seal failure, and the power steering pump being faulty due to fluid loss. The dealership advised replacement of the power steering rack and pump and stated the vehicle was unsafe to test drive due to its condition. During the same inspection, the Audi dealership also identified additional serious safety-related defects, including a brake system condition where the brake pedal slowly sinks toward the floor when pressure is applied (indicating a braking system performance failure requiring brake fluid exchange and further diagnosis if unresolved). The inspection also documented multiple additional mechanical and safety concerns requiring extensive repairs, including suspension and drivetrain defects and other conditions indicating the vehicle was not roadworthy as sold. The vehicle remains available for inspection. This incident involved a sudden loss of steering assist and braking abnormalities that could lead to loss of control, crash risk, and injury to the driver, passengers, and other motorists.

There have been continuous indicators by way of the check engine light repeatedly appearing on my vehicle's dash for a number of years. A different determination was always discovered each time I took my vehicle to the only Audi Certified Dealership in my area. Most recently, I have been told that my vehicle now requires a Fuel System Replacement, High Pressure Fuel Pump, All Components in Fuel Tank, Fuel Rails, Injectors, All Rubber Fuel Lines for a cost of $16,830.50. Coincidentally, I received information by mail from the manufacturer (Audi), indicating there was a Safety Recall 20W9--Fuel Pump Flange for this exact same issue, and that my vehicle had been identified amongst the other reported 143,214 vehicles, as affected. This information was dated October 6, 2016. I immediately contacted my local Audi dealership to schedule an appointment to discuss next step options to resolve this recall issue, and was told then by my assigned Service Technician that the parts were not available at that time to render repairs, but I would be contacted when to bring my vehicle back in. Subsequently, I don't recall ever having that particular issue get resolved because a plethora of other issues related the countless times the check engine light regularly appeared became priority. Now I'm eing told that the exact recall issue I was notified about years ago is the latest identified problem and totally my "financial responsibility", because it's not being covered under warranty. This is as much of a safety issue now as it was then, but never got directly addressed or settled. Thankfully due to my awareness by being the regular, primary driver of my vehicle, I have been diligent in reporting check engine light ndicators, along with any other mechanical light issues each time they've appeared, and there have been no incidents or accidents posing a major threat to my safety. Of course, I wish to keep it this way when operating any vehicle on the roads I travel.

On November 2, 2015, the Environmental Protection Agency and California Air Resources Board informed Volkswagen Group companies that my Model Year 2012 3.0L Turbo Diesel Injection (TDI) vehicle did not comply with Federal and California emissions standards. In the approved emissions modification, Audi Lynbrook claims to have removed the software that reduced the effectiveness of my TDI's emission control system and to have installed new emission control software designed to function effectively in all normal driving conditions. NOTE: this "fix" that was devised to meet emission standards was never actually tested for "vehicle reliability, durability, performance, drivability or other driving characteristics", and by their own account would consume 40% more DEF [XXX], meaning it's stressing the emissions system 40% more than designed. Since the TDI Modification my 2012 Audi Q7 TDI is having constant emissions system faults with 200 mile shutdown ransomware programming, and repeated replacement of the same components. It has rendered the vehicle as unreliable and now unusable unless I keep paying for Audi's "fix". My vehicle had no such issues prior to the TDI modification and received all regularly scheduled maintenance at Audi Lynbrook. I have compiled all my service records including the TDI Modification (7/26/18) then 9 emissions system failures (XXX). Currently, Audi Lynbrook states that again emissions component replacement is needed, a part (rear nox sensor G687) that was replaced 4/10/2023 just 20 months for the second time since 11/12/2020. This failure to deliver a reliably working vehicle has already cost me considerably, so Audi has disabled my car with shutdown programming, taken it hostage needing proprietary Audi service, and are now demanding ransom to make it temporarily usable.

VEHICLE HAS NOT EVEN REACH 92K MILES AND THE WATERPUMP IS A ALREADY FAILING. AUDI THIS IS A KNOW ISSUE BUT THE REMEDY HAS NOT BEEN FIXED. THEY ONLY WAY TO FIX THIS IS TO REPLACE WITH NEW UNIT. I UNDERSTAND AUDI SPECIFICALLY MADE A "WEEP" HOLE TO WARN THE OWNER BEFORE THE WHOLE UNIT FAILS. THIS CAUSES COOLANT TO LEAK WHICH EVENTUALLY GIVES YOU THE LOW COOLANT LEVEL WARNING ON THE DASH. THIS IS TO PREVENT THE BEARING INSIDE THE WATERPUMP TO COMPLETELY FAIL CAUSING METAL TO METAL CONTACT THUS CAUSING SPECS OF METAL INSIDE YOUR COOLANT SYSTEMS. IT'S UNFORTUNATE THAT THIS FAILING EARLIER THAN ANTICIPATED CONSIDERING VEHICLE HAS NOT EVEN REACH THE 100K MILES.

2012 AUDI Q7 3.0T S LINE PRESTIGE, 91K MILES! STARTED AS SMALL GASOLINE SMELL BECOMING STRONGER THROUGHOUT THE NEXT COUPLE DAYS. SMELLED REALLY STRONG AROUND REAR LEFT DOOR AREA AND INSIDE CABIN. INVESTIGATED FUEL LEAK AND NOTICE UNDERNEATH THE SUV, FUEL DRIPPING DOWN THE SIDE OF ONE OF THE TWO FUEL TANKS. DISCONNECT BATTERY, REMOVE REAR SEAT TO ACCESS FUEL PUMP PANEL ON THE FLOOR, DISCOVERED LOTS OF FUEL LEAK NEAR PUMP AND ELECTRICAL CONNECTORS. NOTICED THAT THE FUEL FILTER HOUSING ALREADY HAD "AUDI'S QUICK FIX" (PROTECTIVE FILM) COVERING THE AREA BUT IT WAS STILL LEAKING. NOT TO MENTION THE PUMP'S ELECTRICAL CONNECTORS WAS SOAKED IN THE FUEL THAT HAD THE FUEL PUDDLE! THIS ISSUE SHOULD HAVE BEEN FOUND WHEN I HAD A RECENT SAFETY RECALL CODE 20W9 DONE AT AN AUDI DEALERSHIP JUST A COUPLE WEEKS PRIOR. IN ORDER TO FIX THE LEAKING ISSUE, I HAD TO BUY A NEW FUEL FILTER W/ FLANGE, "PROTECTIVE FILM", AND A SOME SEAL RING.
