Anyone heard of a 458 crank bearing failure yet?

No clue. What were the symptoms on your car?

 

What year? Miles?

 

what year is your car? It's great that you are getting a brand new engine, it's like having half a new car, but bad that you have to break it in again

 

more reason to put miles on these cars so that most of the issues would appear within the warranty period.

 

Did you have an extended warranty? Thinking about getting one foe my mid year 11.

 

Remember when they replaced those "100" crankshafts because of a miss calibration on the machining?

I always wondered...

 

This came to my head also.

 

The powertrain in a 458 is, what, roughly $100k to replace?

Very, very, very, very few of these cars get to even 20,000 miles before the end of the 3-year warranty (heck, I'd venture the majority don't get to 10,000), so we really have virtually zero information on the longevity of these powertrains (except for a few negative events with the DCT and the engine "recall" matter).

So...purchasing an additional 7 years of warranty (power cube, then power "normal", then powertrain) over the years 4-10 is perhaps good insurance...I am guessing/estimating the 7 years of warranty costs around $35k in total. So, its not trivial, but the early years (years 4, 5, 6, 7) power cube and power normal cover much more than the powertrain.

 

So, you think spending $35K to insure against a $100K possibility is a good bet.

Do you really think there is a greater than 30% chance of a catastrophic engine failure over that time-frame ?

Anyone have any idea of rate of comparable failures on current 10 year old F cars ?

 

Haven't given it any real money in the table thought...that's why I said "perhaps". Importantly, it isnt actually a $35k vs $100k decision. It's actually $4-7k for 12 months of "insurance" against breakage. Tough call for sure. I can say I tried to buy PowerTrain for my CS, so I was willing to spend $3k to protect the PowerTrain for one year...

 

Good to know. Are you under warranty?

 

Don't know if I want to get a full two year warranty that covers everything for 9900, or just add year of power train for 4400.

 

This is very scary. Wonder if it was part of the crank machining issue? The problem, of course, is that most of our cars don't get driven enough miles in the warranty period to find out things like this. Please keep us posted if you get further information regarding root cause.

 

I am sure there is some real data out there, but as a hypothesis or two...

If we can agree that 1 mile on a race track is equal to 10 equivalent miles on a road car, then we might refer to the several hundred 458 Challenge cars out there

They too had some of the initial DCT teething pains (same issue). I raced a 13,000 km car at Mugello last year, it had been serviced and not yet rebuilt. So let's make a wild guess that it was run the equivalent of 100,000 road miles. The thing still pulled like a train; perhaps not as much as a newer car, but it ran. I have yet to hear of a rash of crank bearing failures, but again, would love to confirm that with data.

Curious as to when the OP's engine was built relative to the prior recall. Glad they are handling this well and taking care of you.

Good news (?) is that the DCT's are now becoming more field serviceable, so in the event of a problem, repair is an alternative to a swap.

 

Really great point. I imagine that the bottom end of the 458 challenge car is identical to the street version (?).

I would agree that a racetrack mile is at least 10 street miles, maybe more.

 

Yes, the very early engines had this serious recall.
It is great that they are stepping up and doing the right things to resolve this quickly
