...or in another 10 years.

Well mine went at 113k miles so that's a little better. Also I had been running the fuel low several times before the failure. I guess the pumps use fuel for cooling and so when you run the tanks low it causes the pumps to fail sooner. So just keep above 1/4 full and you should not have to do this again for many years.

By several times - how often was it?

Prior to failure, I was doing mostly really short runs in the morning when the engine was bone cold ... and no longer trips after.

Maybe half a dozen times and I also had been doing a lot of cold runs and short trips. But when it finally failed it was after I had just driven 400 miles.

Oh ok. Since September this year, I had been driving my kid to school twice a week and early in the morning (prior to normal school hours for tutorials). Each of those trips lasted less than say 8-9 minutes round trip. Then the car does not move until may be the infrequent longer trips. It is mid-November when the pump fail so I'd say it is way less than 400 miles.

One time, about a week prior to failure, it will not start in the middle of town (another short and unrelated trip). I yanked out the fuse for the ignition, put it right back in - and it started without an issue.

I would say I do run the gasoline tank to the fuel low warning light before I go fill up but I have been doing that for a number of years now?

So does that sound like a disaster in the making or what?

I guess I am trying to prevent it - if preventable - and you'd think Porsche would have known about this issue while testing the Cayenne in extreme heat, etc.?
