2017 AUDI Q7 Fuel/propulsion System Problems

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.

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.

The gasket seals and the seals on the cylinder are not sealed causing fuel to peak from fuel injectors

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)

Every week the vehicle is saying add 1 quart of oil to continue driving

I was driving on the freeway at 60 MPH when pushing on the gas pedal, the Audi Q7 2017 started to de-accelerate from 60 - 30 and then went lower. The gas pedal then locked while still on a lane on the freeway and luckily I was able to quickly move to the shoulder of the freeway. From there my car proceeded to not start and kept flashing low battery, telling me to put it into drive. I could not put it into drive to start the car. There were NO WARNINGS as the car lost speed on the freeway and a mechanic has determined it is the fuel pump. This was a very scary incident as my two young children and dog were in the car and if I hadn't been able to move to the side quickly, we would have been stopped in the middle of a busy city freeway. Additionally, it took a tow truck two hours to reach us. I keep my car well maintained with service.

Start/Stop system malfunction. The vehicle gave me this warning and the vehicle almost stopped completely in the interstate while doing 65mph. The warning disappeared after couple of times of turning the car back on, but it appeared once again. It looks that their are many complaints and a class act lawsuit on Audi about this problem but no recalls. It's dangerous and really mind blowing that nothing has been done on this issue.

On my way to drop my child off at school, I stopped to refuel my Audi Q7. Upon inserting the nozzle to refuel the car, gasoline immediately began jetting out of the fuel door before the auto-shutoff kicked in, covering myself as well as my vehicle. Thankfully, the hot exhaust did not ignite the liquid or fuel vapor potentially causing a deadly fire. Despite having no fuel remaining, I was able to take the vehicle to our local mechanic where they discovered a TSB denoting this specific issue. The TSB was initially released 04/28/2016 for Model Year 2017 Audi Q7s. It was subsequently updated to include Model Year 2018 Q7s as well. This is a documented factory safety defect that denotes if this issue is to occur, to replace the whole fuel tank. Further research shows that a valve inside the non-wear, non-serviceable fuel filler neck can become dislodged and nearly completely block the filler neck from accepting fuel. This can cause a potential safety issue as the result of this blockage, the vehicle as well as driver can become doused in gasoline before a pump's auto-shutoff can kick in due to the shallow depth of the fault. The problem is known and documented as being an issue nearly immediately after the Model Year 2017 Q7 line was released. There was no prior warning or indication that this could occur at any time filling the vehicle.

The fuel tank has a broken flap in the filler neck. Per the NHTSA ID # below, this issue is a known issue. My vehicle is experiencing this issue and will not allow me to put fuel into my car. I am unclear why the NHTSA feels that this is just a technical bulletin rather than a recall. Why should the consumer be subject to replacing a faulting known design by the manufacturer, Audi, in this case. I am now going to have to pay an extract few thousand to have this issue resolved. This is completely unfair to the consumer. NHTSA ID Number: 10150656 Manufacturer Communication Number: A201804 2044039-

OUR Q7 IS LESS THAN A YEAR OLD. I SMELL GAS WHEN I PARK THE CAR EVEN AFTER A SHORT DRIVE OF ABOUT 3 MILES. THE IDI SERVICE HAD SAID THAT THIS WAS RELATED TO VACUUM PUMP AND FIXED IT LAST WEEK. I STILL SMELL GAS AND I AM CONCERNED WITH SAFETY. I SAW PREVIOUS MODELS HAVE BEEN RECALLED DUE TO POTENTIAL FIRE DUE TO GAS LEAK AND I AM WORRIED THAT THIS MIGHT BE THE CASE WITH 2018 MODELS AS WELL.

Mileage: 5,000

SMELL OF GASOLINE WHEN IN THE GARAGE AND IT TURNED OUT TO BE A LEAKING FUEL RAIL.
