Does this count?

I think this is a legit denial based on catastrophic failure linked to engine over rev because of missed down shift.

Amen and if the motor breaks, you just have to fix the motor! Not the end of the world........

Probably...so we have 1. I never said it hasn't happened - there are probably others...but you don't see many reports. Did your search criteria turn up any others?

Didnt search. Just remembered within the last week the lad that stated he doesnt know how to downshift and had an engine failure of some sort. Read the post since it is quite funny. Almost difficult to believe the owner.

I almost just bought a car which was CPO'ed but had a pretty ridiculous DME scan.

Range 1: 48,779
Range 2: 11,729
Range 3: 2,931
Range 4: 504
Range 5: 5
Range 6: 0

The car itself was clean, with a perfect maintenance record. It did have 2-3 previous owners though. I'm frankly surprised that the dealership would CPO a car with a DME scan this bad.

If the dealers aren't concerned, then why should we??? They don't even screen for over revs taking cars in for CPO. So if they can warranty a car with apparent over revs then how can they deny a claim for over revs??

This exactly is what i have been trying to tell all this time...

To a layman, all cancers are terminal (life ending) and all head injuries are fatal but ask a physician and he might not be concerned about the cancer or the serious head injury.

The point is, there are just too many variables when it comes to over revs and just 'coz a car has few over rev doesn't mean the car has a salvage title.

There's a reason why Porsche CPO cars even with over revs but then again some of us here on the forums probably knows some thing about over revs that even Porsche themselves don't know

These overrev threads take on a life of their own. I know someone who had a money shift in stage 6 and had catastrophic damage. These things do count. Stage 5 is bad and can be a money shift if enough ignitions occur. 4's are not really a huge deal unless there are a ton of them. 1-3 are not a big deal at all. 1 is just bouncing off the rev limiter on an upshift, or get counted as you pass through on your way to a higher stage. You will know because they occur at the same time all the way through the range. If i see a car with a lot of ignitions in stage 5, forget buying it. 1-4 I am not worried. 6 and I wonder why the car is still running.
