Hi guys - I'm looking at a used 2018 Panamera Turbo with 78k miles on it. Read some posts on turbos failing around 80k. How many miles to these cars have in them? Not just the turbo, also all other components of the car. Thanks!

Water pump on the 4.0TTV8 might be problematic at high miles. A member in the Cayenne section has a high-mileage-for-age vehicle, close to 100k miles. He is on his 3rd or 4th water pump. His view is high mileage per year is hard on the pump. Not many other members in the Cayenne section have 100k miles yet, so not many data points.

There might have been a fuel pump replacement or two, but not widespread. I haven't seen failed turbos on the 4.0TTV8 reported yet, neither bore scoring nor valvetrain problems.

These cars are not driven high mileages per year, in general. There is always the exception, but those are in the minority. So hard to make a clear statement on 4.0TTV8 longevity.

Porsche suspensions seem average or better life and reliability. Air springs will fail over time, as will ball joints and bushings. It's the nature of the beast.

Thank you for taking the time to respond in detail. I really like the car just concerned that this will end up being a money pit. I also intend to drive a lot (probably 12-15k every year, so maybe this is not the best option to look at for me :-/

Here in Europe you see a few Turbo/Turbo S with over 100k miles... There doesn't seem to be massive issues with them as long as they're looked after.
In stock trim the engine isn't really overstressed... and being shared with the Contis and RS6 (and cayenne...), I think they're pretty bullet proof.
May be in the cayenne case more people use them with a trailed hitched ?

Fundamentally, Porsche (unlike, say, Ferrari) makes quality cars with the engines and trannys good for 200K, on average. I would not sweat it if you are confident that it has been well maintained. Usually owners of performance cars like the Turbo take good care of their cars. I would be more worried if it were a lesser model. Also, understand that you are going to put money into it for repairs, which (as you doubtless know) are expensive for a Porsche. Factor repairs into what you pay up front.

`19 Cayenne Turbo.
About a year ago, with sufficient planning and preparation, I lived 'roofless' for a few months. I pulled about 3500 lbs of trailer from Utah to Houston and back, sort of, I stopped in Tucson. I put about 30,000 miles on the Cayenne last year. It did fine. But, the water pump was changed in November. And now a check-valve in the windshield washer system has failed. While I was staying in a VRBO, the car threw a plethora of codes and wouldn't idle. The local dealership gave me a loaner, and spent four weeks learning that there is a valve in the crankcase vent that causes this. That may be as bad as it gets.

Thanks for the post. How many miles on the Turbo now?

I usually idle the engine for a minute before shutting it down to cool the turbo bearings.

I have 56K on mine and have no issues. Also with idling there is a cool down function that keeps the fan on to blow air into the valley over the turbos for about 30-40sec after you shut off the engine.
