2012 Audi Q7 problems

STEERING

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.

The contact owns a 2012 Audi Q7. The contact stated that upon starting the vehicle, there was an abnormal odor inside the vehicle with the check engine warning light illuminated. The vehicle was taken to a local dealer to be diagnosed. The contact was informed that the high-pressure fuel pump and the fuel system were faulty and needed to be replaced.

ENGINE

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.

FUEL/PROPULSION SYSTEM

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.

FUEL/PROPULSION SYSTEM

RECALL 20W9 WAS COMPLETED ABOUT MAY 2018. NO LEAKING OR CRACKS WERE FOUND. BUTYL TAPE WAS PLACED OVER FLANGE TO "PREVENT" FUTURE LEAKS. AUGUST 2020, FUEL FLANGE IS NOW LEAKING. STRONG GASOLINE SMELL FROM OUTSIDE OF VEHICLE. DEALERSHIP SERVICE DEPARTMENT CONFIRMS IT IS LEAKING. REFUSE TO COVER COST OF REPLACEMENT. THE ORIGINAL "RECALLED" PART IS STILL IN VEHICLE. WHY WILL IT NOT BE COVERED NOW BECAUSE THE PART LASTED A FEW YEARS LONGER THAT OTHERS. IT STILL HAS FAILED AND THEIR BAND AID HAS FAILED.
