Last year I bought my Audi q7 2008 3.6 v6 and This car really smells like gas so bad on the inside. It’s becoming so strong my garage smells like it too and my children are complaining about headaches. I now also have an Audi q7 2013 3.0 v6 supercharge gas. And this one really has that same leaking strong gas smell. There’s even mentions of it on the invoice from the shops I’ve been to. Sometimes I can smell it then others it’s irresistible and I don’t know if me and my children or others on the road or safe.

The fuel pump flange repair was a joke on this car. It should've been replaced not just put a black tar like sealant on it. That was an error on Audi's part. The sealant didn't keep it from forming a leak in the stress cracks that were being reported. Mine says all recalls have been completed. I just experienced a very bad fuel leak from the fuel filter/pump flange. I investigated the issue myself and found a black tar like sealant on top of the filter. That didn't stop it from cracking and leaking as was being reported in the first place. I have photos and video of how bad of a leak. Audi should do the right thing and replace every filter that they (sealed). That was not a fix. it was a blind shot at a fix. Audi should have a lawsuit against them for the repairs and wasted fuel that Audi customers have endured!

My gas tank started to leak while I was driving putting the my safety and the safety of my entire family at risk. This is know major recall 20Z8 that Audi has never got to fix properly. The recall remedy demonstrably did not prevent the failure it was issued for. This is an active fuel leak with fire risk. I'm requesting Audi cover this repair.

My 2018 Audi Q7 3.0T Quattro is experiencing extreme oil consumption — dropping from full to minimum level in approximately 230 miles. This is approximately 14x beyond Audi's own threshold for excessive oil consumption of 0.5 quarts per 1,000 miles. Documented timeline: May 2026 (88,692 miles): Oil change required 2.2 extra quarts beyond standard 7.2qt fill. Low oil light triggered during highway travel. June 27, 2026 (90,200 miles): Authorized Audi dealer formally documented "oil consumption is very high" in their service system and scheduled an official oil consumption test. June 28, 2026 (90,351 miles): Audi MMI system showed oil near minimum after only 151 miles. June 30, 2026 (90,397 miles): Audi MMI showed oil at Stage 2 warning after 197 miles. June 30, 2026 (90,430 miles): Audi MMI showed oil at minimum line after 230 miles total. All readings documented with timestamped photographs from Audi's own MMI system. The authorized Audi dealer has documented repeated oil top-offs in their service system. Audi USA Customer Care was contacted on June 30, 2026 and denied goodwill repair citing no active recall and vehicle out of warranty. An open case has been filed with Audi USA. The engine lubrication system appears defective. Oil dropping to minimum in under 230 miles without adequate warning poses serious safety risk of catastrophic engine failure while driving at highway speeds. The authorized Audi dealer has scheduled an official oil consumption test and inspection for July 2, 2026. Results will be available upon request. Vehicle is available for inspection upon request.

Front right Marker light defect alert keeps pooping up and sounding an audible alarm while I am driving even through the marker light is working perfectly. Drive train alert comes on after I add oil and the vehicle starts hesitating while I accelerate.I just got a tune up which included new spark plus and a new coils. Problem came back even after the tune up within 3000 miles. Excessive oil loss. I constantly have to add a quart of oil even after I just got an oil change and tune up. Seeing oil in the cover shield that covers the entire engine. Seems like the oil is blowing out of the cap area where you add in oil. These problems are very costly for a vehicle that I ordinary love. Please advise what can be done because I can not pay for any more repairs out of pocket. There is only 80,100 mile on the vehicle.

My 2020 Audi Q7 with 49,500 miles had a complete engine shut down while driving. Towed to Audi. Fuel Pump was recalled and replaced on 1/2023. Audi stated it was the jet suction pump inside the saddle fuel tank. Research discovered that this saddle tank has been problem for this model and year. Audi only covered a portion of the cost. The entire fuel tank had to be replaced. 16 days to complete.

The vehicle is leaking fuel like it did before the recall in 2016. Fuel puddle under car after sitting for 3 minutes huge safety problem. The recall was done 9 years after the car was sold and it’s been 9 years since the recall was done and the problem came back, meaning it was never actually fixed, since it lasted the exact same time it took to break the first time.

The crankcase ventilation valve is malfunctioning resulting in excessive oil consumption and unsafe idling. The Extended Warranty dated 5/24/19 with Number AWA-19-03 should be extended to other model years.
NHTSA complaint #11705971 — an unverified report by a vehicle owner.
I am submitting this complaint regarding a serious safety issue I experienced with my vehicle. Shortly after starting to drive, about 2 miles from my home, while traveling at approximately 25 mph, the vehicle suddenly began to shake violently and came to a complete stop at the intersection of Crescent Street and Astoria Boulevard. At that moment, I lost all control over the steering wheel—it completely locked up. The dashboard displayed the message: “Drive System Malfunction – Contact Service.” These diagnostic trouble codes (DTCs) appeared: •P2179 •P025C •P0087 •P0306 This incident posed a major safety risk, as I was unable to steer or move the vehicle in a high-traffic area. I am very concerned that this could happen again or to other drivers under more dangerous conditions. Please investigate this matter as it may indicate a serious defect that could affect others.

Drive System malfunction code appeared while driving. Engine then shut off immediately. Had it towed to Audi dealership. Fuel Pump and Fuel Pump Module Codes reported in diagnostics check: codes P3044, P1158, and P0148. There is a NHTSA campaign number 22V516 (Audi recall number 20DR) that has been reported on this same issue with the fuel pump, however, my model 2019 is one year shy of the 2020 Q7 to 2021 affected vehicle range. Asking NHTSA to look into other repeated fuel pump issues for the same model vehicle, but for 2019 models. I have read of other 2019 model fuel pump complaints that match the 2020-2021 recall. The 2019 models need to be included in the investigation and recall.
NHTSA complaint #11691309 — an unverified report by a vehicle owner.
My 2017 Audi Q7 Prestige 3.0T 6Cyl GAS CREC Supercharged has experienced repeated, serious failures involving the engine, powertrain, and fuel system. - At 72,000 miles, the vehicle developed coolant leaks under the supercharger, a failed water pump, and soaked drive belts. Repairs included multiple hoses, gaskets, and thermostat replacement. -Shortly after, repeated PCV/Oil system failures caused oil leaks, warning lights, and engine shaking. Repairs included PCV system, oil separator, valve cover gasket, breather pipes, and new spark plugs. - at 111,000 miles, the low-pressure fuel pump and relay failed, causing the vehicle to stall and lose all power while driving- a major safety risk. -Most recently, the engine developed a severe misfire in cylinder #4. Compression testing confirmed abnormally low compression (15 psi) due to a suspected cracked valve seat. The vehicle cannot be repaired without a complete engine replacement, quoted at ~$20,000. Safety Impact: - Vehicle has stalled suddenly in traffic due to fuel and engine failures, risking crash or injury. - Coolant and oil leaks present a potential fire hazard. - Loss of power and shaking while driving put my family and others at risk. Inspection/Confirmation: -All problems have been repeatedly confirmed and repaired by an independent Audi specialty service center (S&S Auto Repair). - Numerous invoices document coolant, oil, fuel, and engine failures. Warning Signs: - Multiple dashboard warning lights appeared either right before or during failure, including engine malfunction, coolant loss, and auto start/stop malfunction. These repeated failures at relatively low mileage suggest a design/manufacturing defect with the Audi 3.0T engine platform that compromises both safety and reliability. The issue seems to be widespread amongst other Audi owners with the same 3.0T engine- Per AudiWorld Forums.

Warranty will be over in 60 days; the Catalyst Coverter is going back, the Audi dealer and Audi Corporate are delaying the fixture do to some mis communication between dealer and corporate. The problem has to do with DEF gases not being cleanup. The error code is P20EE00 and the engine light is on. The part is under warranty and Audi Corporate is delaying the fixt because the do not wish to pay for the cost. They have had my vehicle for a full week and no decision when to replace the part. I strongly believe they want the warranty to expire so the customer has to pay for cost of the catalyst. The dealer has verified that part is under warranty but corporate does NOT response to the dealer.0
NHTSA complaint #11682233 — an unverified report by a vehicle owner.
The contact owns a 2014 Audi Q7. The contact stated that while the vehicle was parked, there was an abnormally strong fuel odor coming from the vehicle. There was no warning light illuminated.

NHTSA complaint #11666829 — an unverified report by a vehicle owner.
I am reporting a serious issue with the 2017 Audi Q7 involving excessive oil consumption. The vehicle burns 1 quart of oil every 1,000 miles or less, requiring me to constantly add oil between regular oil changes to avoid engine damage. This is not normal and poses a serious safety risk if the engine runs dry during operation. Audi denied my buyback request without inspecting the vehicle or reviewing service records. Instead, their solution has been to provide free oil top-offs, which proves they are aware of the problem but are avoiding a permanent fix or recall. Other Audi Q7 owners, even with newer models and low mileage, report the same defect. This is a manufacturing defect that makes the vehicle unreliable and unsafe for normal driving. This can cause the vehicle to stall or stop suddenly while driving, especially at high speeds or in traffic. That’s a major safety risk. If the oil burns too quickly, the warning may come too late. The need to constantly monitor and add oil makes the car unreliable for everyday use. Regular oil changes are meant to keep the car safe and working smoothly. But if oil is burning quickly between changes, the car can’t be safely operated on a normal maintenance schedule, which defeats the purpose of service intervals and puts extra responsibility and risk on the driver. Audi’s refusal to issue a recall or perform proper repairs is deceptive and dangerous. I request NHTSA to investigate this issue and determine whether a recall is necessary for this known defect. It also breaches Implied Warranty of Merchantability (UCC § 2-314)
