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.

2017 Audi Q7 with approximately 112K miles consuming oil at a rate of approximately 1qt per 500-700 miles. Misfire occurred on highway and then cleared overnight. Took to dealer and had them swap all coil packs and spark plugs. Approximately 500 miles later, multiple misfires in cylinders 3,5, and 6 and loss of compression while driving on highway at 70 mph. Vehicle taken to dealership where they completed diagnostics. 0 psi compression in cylinder 6, damaged cylinder walls, and broken valve. Cost of repair estimated at $25K.

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.

The contact owns a 2017 Audi Q7. The contact stated while driving at an undisclosed speed, the low oil level warning light illuminated with a message that the engine was 1-quart low on engine oil. The contact added 1-quart of engine oil. However, after driving 1,000 miles, a message indicated that the engine was 1-quart low on engine oil. The contact became aware that the vehicle was consuming an excessive amount of engine oil. The low oil warning light was illuminated. The vehicle was not taken to the dealer or an independent mechanic to be diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 111,000.

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 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.

Oil consumption increased over time to 1qt per 400 miles causing engine misfire in cyclinder 5 then 2,3. Engine now requires exhaust valve replacement and or complete replacement or overhaul at 140k mileage. Problem started at 90k miles.

Engine oil consumption, suv requires a quart of oil in between oil changes. Also head light gives warning sign of the side marker being faulty.

I bought my 2017 Audi Q7 on November 16, 2023 (Used) and a couple of days after putting the headlights on Auto I get a message pop up "Front left side marker light defective See owner's manual". Also kept getting a low oil message. This model have no oil stick so I put about a 1/2 qt of oil in it to see if the message goes away. It goes away for a few hours. The vehicle basically stopped running leaving myself and kids on the side of the road in the winter while we wait for a tow truck. After getting it towed to Mentor Audi dealership, they gave me the bad news that the engine needed to be replaced. My engine has been replaced and documents can be sent upon request. After doing some research, I found out that these are common issues with the 2017 Audi Q7. NHTSA campaign ID 16V642000

PCV valve and PCV solenoid failure. Covered under an Audi extended warranty for 2013-2016, but not 2017. Exactly same failure.

- Victoria, MN, USA

I got the checking engine malfunction. took it to the dealer for dianogtic found code P052E001 PCV ( crankcase breather valve fault and it need to be replace because it also caused the emission issue). I found it was under extentison warranty to 10 year or 120000 miles, I contacted Audi and they said my VIN is not eligible to the warranty. I believed they should provide the extension warranty for all of their vehicles.

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.

Cylinder 2 began to misfire at highway speeds. Diagnosed with a burnt exhaust valve in the engine. Possibly also due to the high oil consumption of greater than 1 quart of oil every 1000 miles.

Engine mounts are leaking at 118,000

We purchased a 2017 Q7 with low milage. At around 75k miles the engine started consuming oil every 1,200 miles, when previously it never required an oil change before the regularly scheduled service. The dealer always said "that is 'in spec'". This went on for over a year. Then, when we were driving cross-country for thanksgiving in 2022, the engine made a major concussive noise and we lost power while driving on the freeway at around 70mph. This almost caused a high speed collision. It was winter and we had the entire family in the car. we took it to the dealership, and the service tech recommended a compression test and borescope. No carbon build-up was found. Pressure was 'ok' in all cylinders. There were codes showing a fuel injector misfire, so the dealer recommended replacing all of them. The repair was done, but we've continued to have excessive oil consumption, the engine continues to run rough, and we occasionally get 'drive system malfunction' errors. When driving cross country in sub-freezing winter weather, last week, the engine lost power again. I stopped at the nearest Audi service center two hours later, and the tech found that the spark plugs had significant carbon fouling. Spark plugs were replaced. Engine continues to consume too much oil. Based on my research, it appears that this is a known issue, with several class action lawsuits. The Q7 does not appear to be part of these suits (yet), but there are posts and forums all over the internet with owners reporting this problem.

Engine mounts are failing on Audi Q7's at high rates just out of warranty. This is resulting in costly repairs to owners at extremely low mileage. On mine the engine mounts were shot at 54k miles and results in clunking from the engine moving around and shifting issues in the transmission. Audi is aware of the issues and is choosing to ignore it.

- Getzville, NY, USA

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.

Car issued an alert for Low Coolant, I checked next morning only to find that the coolant tank was empty. This warning could have alerted long back when the level fell below "Min" marker. Owners cannot notice this leak because the coolant doesn't drip on the floor. Took it to an independent service center who alerted me about this issue. I researched and noticed that there's been a lot of complaints on forums for 2017 Audi Q7 3.0 for coolant leak cause by the water pump, which always needs replacement. The replacement costs by AUDI are upwards of US $1300. This issue seems like a regular pattern and can cause an engine failure. AUDI should take responsibility and fix these cars.
