You're misinterpreting. Ford does endurance testing to 150K miles on all their engines. That doesn't mean it won't go 300K miles.
It's not going to fail at 151K.
Long term (10-15) years reliability of the turbos is unknown. It would be a bit less risky to stick with the 3.5L NA but I don't think we've seen anything so far that indicates long term problems are expected. These turbos are designed with the engine and use much better materials than the older ones.
Warning: Long drifting post here (LOL).
I don't think I said I expected it to die, but you have to admit if the average life of something is 10 years and you plan to keep it 12-15 years, that puts you in pretty good spot to have it die before you're done with it. Although without the actual underlying data, would be hard to tell what the curve is after the "average".
Which part of this am I misinterpreting?
"In service, the turbo spins at up to 195,000 rpm and is designed for a life cycle of 150,000 miles or 10 years."
You state factually that it won't fail at 151k, are you going to insure financially that doesn't happen? I'm sure you rather meant that it *probably* won't fail at 151k. And if it's a true median (vs. mean), then 50% will fail prior to 150k or 10 years and 50% after that.
I'm assuming (perhaps incorrectly) that it's lifespan is more sensitive to miles driven vs. time. ie: You drive 5,000 miles/year (hypothetically speaking), with routine maintenance, the lifespan would theoretically be more than 10 years. However, the quote from Ford was puzzling to say 150k OR 10 years.
Is that like saying, change your oil every 3 months OR 3,000 miles (whichever comes first)? Although I just saw the Kia manual that doesn't say "whichever comes first", so who decides the "or"? You or the dealer/warranty supplier? (Kia oil change manual on the Sorento with Turbo says first oil change at 3,000 miles or 6 months, and subsequent at 5,000 miles or 6 months).
Although I did notice the article is from 2010 and I thought I came across a 2011 article that Ford was discontinuing/replacing the 2.0 Ecoboost with something else (maybe the 2.7?), so not sure if that makes things better or not.
Anyone know the cost to repair/replace said Turbo? I mean if the "average" is 10 years, and it's like $2000 for the turbo replacement (assuming it doesn't trash the rest of the engine) upwards of 5k (if it does trash the rest of it), I'd think a 10-year warranty (longer, actually) is probably in order.
Unfortunately this is the only manufacturer I can find (at least via google) that publicly stated the lifespan of their Turbo's. Can't find anything on Kia, Hyundai, Chevy, or Toyota (publicly stating the lifespan, there's all sorts of conjecture on various forums).
I mean if it's all turbo's in general get 150k/10 years (how is the 10 year figure derived? Do we assume national average of 12k miles/year, and if so, why then 10 years as that would be 120k miles if the 150k miles figure is accurate?), then that's one thing. If it's specific to Ford (but then again, I can't find any other manufacturer that publicly states what the average span is, so I don't know if any other vehicle is better/worse), then I'd think that would also be something to consider.
However, even on Hyundai/Kia with the 10-year warranty, I don't know if that would cover the turbo (haven't read that far yet), but I think it's usually Powertrain, whatever that means.
Although someone mentioned this in regards to turbo repair (and it's greek to me, I don't know):
"Did the turbo compressor or turbine wheel loose and fins? even a few tiny pieces will travel and possibly end up in the intake manifold or worse: destroy the piston & cylinder.
Did the turbo line spring a leak (like many Hyundai Santa Fe) are having and the engine run out of oil? that will end up in a new engine quickly.
did the turbo destroy the catalytic converter after the bearings allowed to much play and the wheel lost a piece?"
