High Mileage Boxster

[deliriousga]

I'm with Lucky. We have a 2000 2.7L w/ 107K miles and no problems. Just got an oil report after the 106K oil change that says the engine is in excellent shape with no unusual wear at all.

Could go tomorrow or not. You just can't tell.

Drive and enjoy and keep the oil clean.

Keep in mind, this site has a paying sponsor who sells expensive preventive
mods to your engine. "He who pays the piper calls the the tune."


I will try to address this without becoming too testy!

LONG before we took on the sponsor that you reference, the issue of the Boxe's engine foibles has been a hot topic. This is because folks wrote in to tell us about their engines imploding. This is clearly not the only site where this issue comes up; you can do a Google and fine this all over the internet.

If you were around long enough, you would know that my neighbors brand new box lost an engine at 12K miles, sitting at a traffic light.

That Box engines implode or explode is not at issue. The real issue is that no one has any real data on the subject except MAYBE Porsche and they simply deny the problem is extraordinary. Yet, I have seen the problem first hand and talked to the local SM at length about it. It was real (maybe be fixed now) and it was/is expensive.

Personally, as I have said, I don't know if the problem is statistically signfiicant. What we ALL know is that the repair is very expensive and makes many leary of an out of warranty Boxster.

In the future, if you want to state that we here at the forum are "on the take" then I suggest that you check out your facts. Believe me, to buy my integrity would cost a lot more than any sponsor pays on this site, or any other for that matter.

In fact, I am not sure how much it would cost as no one has ever tried to do it!

Did not state that you on the forum "are on the take." You reported your first hand observations and I take your word for it. But those are anecdotal.

"Facts" are what we need. I supplied some objective facts.

Your integrity for sale? Sorry, Brucelee. No bidders here.

IMO, there likely no way any "objective" facts will every be gathered regarding this particular issue. As you know, CR data is gathered from folks who voluntarialy answer a survey. This methdod will always create a bias, as any researcher knows. One bias is simply the folks who tend to read CR may or may not be typical of the average Boxster owner. We don't know.

Having said all that, I would love to see real data, which as far as I can tell, could only really be gathered by Porsche. Even that would be limited, but better than any other data base I can think of.

Alas, I don't see this happening. As I said earlier and many times, if the prospect of a grenaded engine is upsetting to folks, I don't see many options: Don't buy the car, buy a warranty, self-insure, bite your nails????

Such is life; you play the game and you take your chances!

okay, I have to pipe in.

My car has 82k, and needs a 3rd engine.

If you want to delude yourself into thinking that bruce is overstating the problem, free country, delude away!

The reality of it is, these engines fail at a higher rate than a ford escort, and your are taking a very expensive gamble.

For those with high mileage engines...I envy you, and will keep you and your engine in my prayers. I wish you many miles of trouble free driving.

I think it's kind of ridiculous to say that the forum is on the take. Do you think Brucelee just makes these posts up? HAHAHA.

I read dozens of horror stories on these posts and concluded that there is a definite failure problem compared to other cars. I also agree that the failure percentage cannot be quantified for a number of reasons. It is scary, but we can draw a pretty good guess that the percentage isn't really high enough to worry about:

NHTSA: 11 reports of Boxster engine failures
BBB: 7 complaints to PCNA about Boxsters, NONE specifically mentioning engine failures
Consumer Reports lists most years of Boxsters as "Much Better than Average" for "Major Engine Problems".

Some people have obviously had more than their share of problems, but with over 200,000 Boxsters produced, if there was a failure rate of even 1% on that amount of production, there should be over 2000 blown engines. People here will cite a bunch of anecdotal evidence to the contrary and even claim a failure rate much higher than that, but their estimates are biased by their own experience. In point of fact, nowhere will you find anywhere near 2000 complaints of blown Boxster engines. In fact, you'll be lucky to identify 200 separate cases (many of the reports out there are duplicates). These well-meaning folks would extrapolate from their own bad experience that there MUST be a huge failure rate, and that is faulty logic.

If there is a major engine failure problem above, say, 1%, then we must logically conclude that 99% of these failures go completely unreported and UN-complained about. However, such a conclusion runs contrary to human nature, especially in the day and age of the internet. There is no logical reason why the 2000 people who supposedly suffered engine failures would remain silent about it. Certainly those who had engine failures in this forum are vocal enough. SO, if these people complain, why not the rest? Why aren't there a whole lot more complaints than there are???

I suspect the actual failure rate is probably 0.5% or less overall. That may very well be 3 times the failure rate for other engines, and therefore I do not excuse Porsche for it. However, if the failure rate is 1% or 0.5%, this means there is about a 99% chance you will NOT have an engine failure. And that's why I think the problem is greatly overstated.

So if I read this correct, there are no posted "facts" of how many Boxster engines fail. Many guesses.. 1%, 2%, 3%... but no hard numbers.

So lets look at other factors. What else fails? Transmissions, wheel bearings, alternators, power steering pumps. Are there other components of the car that fail prematurely? This info may be available from the aftermarket suppliers and re-manufacturers... which would show a trend of the overall realiability of the vehicles.
