2017 Audi Q7 Engine Problems

My 2017 Audi Q7 with the 3.0T engine has experienced repeated engine/ignition system failures. The vehicle displays a "System Malfunction" warning light accompanied by shaking and stalling. This same malfunction has occurred at least 3 separate times over the past few years. Each time, a repair shop diagnosed and replaced faulty ignition coils, and the vehicle ran normally for a period of time before the identical malfunction returned. The vehicle is currently inoperable due to the most recent occurrence. This creates a safety risk because the stalling and shaking can occur while driving, with no clear warning beyond the malfunction light appearing at the same time as the symptoms begin. A stall or loss of power while in motion, especially in traffic or on a highway, could lead to a collision. The problem has been confirmed and repaired multiple times by an independent European auto repair specialist, who stated this is a known, recurring issue with this engine/model. The vehicle has not yet been inspected by the manufacturer directly. Separately, the vehicle has also developed excessive oil consumption, requiring approximately 2 gallons of oil added roughly every 6 weeks, with the frequency increasing over the last 2 months. I am uncertain whether the oil consumption and the recurring coil/ignition failures share a common root cause, but both issues are ongoing and unresolved. The vehicle and its components are 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.

Car has a burnt cylinder from excessive oil consumption due to poor piston ring design. These engines are prone to failure to do carbon buildup on the cylinders which leads to poor PCV performance to exacerbate the problem. Audi dealership has confirmed my cylinder 3 has a burnt valve and requires a new engine.

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.

My engine just failed after over a year of having to put oil in. The car has 77K miles and has been regularly maintained. Audi used this as a "demo car" and after purchase we immediately had to put oil in and were told verbally this is not an issue. The excessive engine oil consumption caused this catastrophic engine failure our an independent and trusted mechanic reports the engine has failed and cylinder number five only has 30 pounds of pressure. Please advise on what I can do with Audi for repair. We also have a 2019 and are fearful this will happen to that car as well. Thank you.

2017 Audi Q7 started consuming oil at 40,000 miles. At 70,000 miles consumption increased to quart every 3,000 miles. At 100,000 miles a quart every 1,000 miles. At 110,000 miles a quart every 40p to 600 miles. This is due to a very well known and documented piston ring issue. Audi offers to do nothing and while I was in warranty they claimed a quart of oil every 1,000 miles was within expected tolerance. This is ridiculous and terrible for the environment. Audi needs to stand behind their vehicles. So may complaints in Audi forum on exact issue.

My 2017 Audi Q7 3.0T with 99k miles and it consumes oil excessively. I am having to add a quart of oil about every 500-600 miles. My local german auto repair shop has told me, in my case that it is extreme & I should be worried. I’ve seen many other people with the same engine with oil consumption & I know it can cause the engine to fail. This needs to be addressed by someone due to how common this problem is with these engines.

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)

Drive system malfunction warning while driving on the highway at 75 mph and the car began sputtering, lugging, jerking and had to be manually shifted to get it safely off the highway. If we had been in traffic we would have been rear ended as the car drastically lost speed on the highway. Dealership initial diagnosis was a misfire in cylinder 4. Upon further inspection we were told that a piece of the exhaust manifold had broken off resulting in catastrophic engine failure and we needed to replace the long block at a quote of $32,000. Car had been serviced only at the Audi dealer and all Audi care maintenance had been completed. We had informed the dealer that the car was burning oil on two previous service visits and we were adding a quart every 1000 miles or so and we were told that was normal for a 2017 Q7 with over 80,000 miles on it. Last service inspection and Audi care package in September 2024 we were told the car was in great shape. Catastrophic engine failure in December 2024.

Oil consumption issue began June 2021 with my 2017 Audi Q7 with the 3.0 engine, we were at 78,841 miles. Our vehicle was always serviced at the dealer on the recommended schedule. The dealer stated high oil consumption of 1 quart per 1,000-2,000 miles was normal. The high oil consumption issues continued. At 99,559 miles the car began shaking on the way home from a routine oil change. They found cylinder 3 spark plug covered in oil and replaced all spark plugs to clear misfires. At 104,002 miles the N428 oil pressure regulation valve was replaced, which seemed to improve oil consumption temporarily, but gradually got worse with frequent top offs. On 1 December 2024 at 123,616 miles the car started to shake while traveling at 70mph on the interstate, with the engine lights on. The dealer found crusted spark plugs and identified that cylinder 1 had a burnt/broken exhaust valve due to excessive oil consumption and residue buildup. The required long block replacement would exceed the value of the car. Clearly a defect in the 3.0 Audi engine.

Driving with the family on interstate 81South when suddenly the car went from riding smoothly to a rough rumbling sensation. Then all sorts of alarms sounded and the engine light, oil light and system malfunction indicator light came on simultaneously. We pulled over immediately and turned the car off. We looked in the manual to check the severity of the indication lights. We wanted to determine if we could drive to the nearest exit. We started it back up to see if it was some sort of glitch. It remained so thankfully we were right near an exit and exited and called for roadside service. It was towed from Christiansburg, VA back to Roanoke Audi at 2006 Peterscreek Rd Roanoke, VA 24017 on Nov 9th. The dealership concluded that cylinder 1 was burned out with a possible damaged long block assy. I have had all services and taken great care of the car. However, in between services the car would always require an additional 1qt of oil.

Oil consumption issue began June 2021 with my 2017 Audi Q7 with the 3.0 engine. Dealer advised this was normal for high performance engines, and it could continue where every 1,000-1,500 miles would need a quart of oil. Vehicle was serviced at the dealer on their regular recommended schedule. With continued oil consumption issues this past year they did part 1 of their oil consumption test September of 2024. A few weeks later the car started to shake when started and the start/stop system malfunction light came on. In cylinder 3 they found oil on the spark plug and changed out the spark plug and ignition coil. A week later the car began shaking again and they performed part 2 of their oil consumption test. It showed oil consumption a 3.61 quarts per 1,000 miles. They then performed a flush of the engine, and said that cylinder 3 was burned up and the engine had to be replaced. The Service manager after seeing how the car was serviced over the 6 years that there has to be a defect in the 3.0 Audi engine.

I have a 2017 Audi Q& Prestige. It started using more oil after 103,000 miles to the tune of 1 qt per 10000 miles. I checked on line and there was many complaints about this on this and different models. People have said it costs around 11,000.00 dollars to fix whatever the problem is. After a period of time, as reported by various on line complaints, the engine starts to stutter and miss. Plugs begin to foul and seat rings for plugs become unreliable and start leaking. It seems to me there should be a recall as these vehicles are very expensive and boost reliability.
