Just curious, as I’ve bought a 2018 G3 V6 Cayenne, how are these working out for you? Are there anything to look out for with the V6’s or for that matter V8’s or Hybrids?

With respect, you probably should have asked before you bought the vehicle? I'm getting my V8 in a couple months so I can comment on that then. Good luck
Hi Odin. This forum is for the 3rd Generation "9Y0" Cayennes. Your car is from the 2nd Generation of Cayennes, the 958, that's a separate forum here on Rennlist. iI you try your question in that forum I'm sure you'll you'll get more/better info https://rennlist.com/forums/cayenne-958-2011-2018-242/

No my Cayenne en route is 3rd gen Cayenne. A V6 340PS 3.0 single turbo engine. Should be here any day now.

Probably wouldn’t made a difference anyway as I got a very good deal on it as everyone wants an EV these days, including 3yrs PAW running from December when the 5yr new car warranty expires.
But I’ve heard about weaknesses in oil seepage between engine/gearbox on the 2nd gen diesels, rumors of bore scoring on V8’s and generally very complex trouble shooting on the hybrids, so asked the question to learn more about my new car model. I’ve had several Porsches and they’ve all had their issues. Are there anything to look out for with the 3rd gen Cayennes, and maybe in particular with the V6’s? Always eager to learn.
While I haven’t read about balance shaft (balancer assembly) problems on this site, the 3.0 and 2.9 have a 90 degree vee cylinder block which requires a balancer. 60 degree vee and inline blocks are more balanced for 6 cylinders, so the balancer is used to address the imbalance from the design shortcoming of the 90 degree V6.
Balance shafts have been problematic across years, manufactures and models. The MB M272 had balancer problems. No guarantee that the two Porsche engines will have a problem, but it is one design feature I don’t care for.

They first used them on the 944 S2’s and then the 968’s to great success. Mitsubishi got them from Porsche on their 2.0 DOCH blocks and they ran great too. Don’t think the balancing shafts will provide an issue really.
The Gen 2’s Aisin transmission has been replaced by the ZF 8HP. No issues (so far) with the transfer case problems that plagued the Aisin. Some folks report a rough 3-2 downshift with the ZF.
In fact, the Gen 3 is a major redesign — from new engines and transmissions to the chassis, which was completely redesigned from scratch. Read all about the changes in this press release titled “The Technology of the New Porsche Cayenne”

Hi Odin, the EA839 3.0T V6 is widely used in many applications across the VAG group. It’s been stout, with untouched bottom-end B9 S4 pushing over 500whp with bolt-on and running low 11s in the ¼ mile (granted its much lighter platform) With an upgraded factory location turbo and fueling it can be pushed even more without any major problems. The transmission is also very stout, but we don’t have any TCU tunes out for 9Y0 to my knowledge. I went 3.0 base over the 2.9 S because of the wide customer base of the 3.0 being used and abused and people finding very high limits, I hope this helps!
I've been loving the V6 in the current gen Cayenne. Recently got 26mpg in a 1,000 mile road trip at 75mph. This was on pretty much flat roads at sea level though.

That has been my experience with my 2019 Cayenne S, 2.9L.
I have gotten up to 26 mpg, over an entire tank on some trips. City/Highway is normally 20 to 22 mpg average per-tank.
I found, too, that the oil/filter service, and engine air filter, on the 2.9L. is very straight forward and relatively easy, using a top oil vacuum extractor through the oil dipstick tube.
Having the oil filter at the top makes it a very clean process. The engine air filter comes out easily during the service process so it works great.

This is exactly why I went with a 3.0 car. My SQ5 with minor mods was just under 450whp and then a new turbo took me into the 500s and the transmission and motor were fine through 20k miles. Which is also why I'm now looking into throwing a new turbo on the Cayenne. Like jsun said, these motors are very, very robust and can take a whole lot of abuse.

Any weaknesses on the V6?
