I’m strongly considering buying a 2019 Q7 55 Premium Plus for a smoking deal that I negotiated (under $20K). It’s got 84K miles, but clean carfax, one owner, dealer dealer maintained. From everything I could tell on the test drive it’s perfect. It’s being sold by a Mercedes dealer and they showed me their inspection report and things they did like an oil change and new tires.

We have other primary vehicles so this would only be driven 2-3 times a week on my wife’s short commute to work which sometimes involves hauling kids to and from school. Probably 6k miles a year and I’d probably only keep in for 2 years.

I’m curious how reliable these vehicles and the powertrains are? This has a 3.0 supercharged TFSI V6. I think earlier and later years were just turbocharged and possibly had oil consumption issues.

I’m debating buying it with no warranty or they can do a comprehensive third party warranty for $3,800 (that’s as low as I could get them with negotiating).

Do you think taking it from 84k miles to 96k miles or so in two years before getting rid of it, I’ll have $3,800+ in warranty repairs? Curious to hear from anyone familiar with servicing these or owning one.

Thanks!

Successor engine is the hot vee EA839 3.0TV6, developing a reputation for water pump failure (internal leak of the active impeller shroud rod seal).

The supercharged EA837 was produced in fairly low numbers. It has iron cylinder liners which is a good thing. Try reading Audiworld posts.

SSP 624 attached.

I had a 2019 before my 2022. It served us well with over 50k miles and no issues (apart from my kids kicking and breaking the rear hvac screen which was a $2k repair). Super comfortable and the Supercharged V6 has far more character vs the Turbo V6 on my current Q7 (more usable torque as well).

My wife still daily 's an 18 Q7 with the 3.0 supercharger. We've had it for about 70K miles and I have kept up with all the normal maintenance on it and no issues for us (knock on wood). The car is one of the nicest riding vehicles I have ever been in and family road trips are very comfortable.

Only real complaint I have with the car is its a 3-row and the storage space is worse then her previous Jeep GC.

Outside of that, the car was been problem free and still looks and drives as good as it did when we bought it.

Go for it!

Appreciate this and all the comments so far!

We've had a 2017 for quite a few years. The common things I'm aware of are motor mounts and water pump, with a class action settlement on the water pumps. I've heard that the supercharger clutch can be a problem. PCV is an expensive replacement when it goes as it's under the supercharger. The most annoying thing I've noticed is the brakes squealing in reverse which also seems very common with owners. The last thing I've been hearing about is oil burning in these due to stuck piston rings.

From Consumer Reports. It seems like the Lexus RX L is the top 3-row from 2019 when considering overall reliability and ownership satisfaction.

The brakes squealing in reverse is very annoying. It was there on my 2019 and again on my 2022.

^Squealing brakes^ is a VAG thing. Just like water pump failure is a VAG thing. Congenital defects.

My Touareg TDI brakes squealed in reverse and now my 9Y0 Cayenne S brakes sound like a trumpet (louder and lower pitched than a squeal) when creeping forward.

Maybe an SUV VAG thing? I've had plenty of VW/Audi cars and none of them squealed in reverse.

Buddy had one. That motor guzzles oil because of an issue with the piston rings. The concern was it would eventually drop a valve and nuke the motor. Supercharger itches are a weak point on them too, as well as expensive break, expensive suspension, leaks, and a few other issues he had.

I don't think I'd buy one unless it was a 3rd car.

Thread below gives examples of cyl 4 failure. As always with internet posts, not possible to discern how common, or uncommon, the failure is. With multiple reports for this issue, I would stay away. Seems like low tension rings get carboned up and cause loss of compression. Allegedly fixable with "Berryman's piston soak" if caught early enough.

The only VAG engines with proven reliability are the long-gone VR6 and current EA888 2.0 4-banger.

The 2019 and I believe 2018 “Q7 55 models” are supercharged 6 cyl vs turbo 4

Yes. EA837 supercharged is the topic of discussion. EA839 turbocharged is the successor engine which has different problems vs the EA837.

The only VAG engines with proven reliability are the out of production VR6 and EA888 4-banger in millions of VAGs produced annually.

The successor to this engine was the turbo V6 not a 4 cyl.

Yes, the hot vee EA839 3.0T 90-degree V6 with iron liners, balance shaft, 4-bolt mains, direct injection, variable int/exh cam timing and variable lift intake cam.

This one indeed

honestly any german high performance car with a lot of miles scares me. audi probably scares me the most, seems to me their failures are catastrophic and costly. they look great and drive well though. that said, my X5M needed a front differential replacement at 60K miles, that was a costly repair. a friend basically gave up an R Series Audi a few years ago for a blown motor, cost to repair simply wasnt worth it.

i do secretly covet an R6 Avant though.
