HPFP failure causes the car to stall while moving?

Ive read all about most of the hpfp stuff. I have no symptoms or anything but I just read two stories where the hpfp failed while driving and the car just stops on the highway? 60+ mph and the car could just stall with not even enough power to get to the side of the road?

How has this not caused serious accidents with all the failures? Having so many failures is bad enough, but I wasnt concerned until I saw that the car can fail while on a highway. Ill be going on a trip later and now im worried. If the hpfp failed while driving and that caused the car behind to hit into the back, who would be at fault?

mine happend during stop and go situation so, "luckily"..if u can call it that, i just pulled it off the road, even though i had to restart the car, and still barely made it off... horrifying experience cuz i can't imagine what if it just happens on the highway :/ now i dont even feel confortable taking it on the highway not knowing if it will happen again..

lol, I could pull over fine. Its the other drivers going 70-80 that might not notice me losing all power instantly. It would be like slamming on the brakes out of nowhere. Most moron drivers arent ready for that.

Luckily, I haven't heard of any hpfp related highway accidents and hopefully I never will. If bmw knows about this problem which they do, and they know that it could cause the car to stall on the highway and someone is hurt because of it, I wonder how much trouble they are going to be in.

Unfortunately that is what it's going to take. Someone is going to die or be seriously hurt as a result of a HPFP failure before BMW wakes up. This is a really pathetic situation really.

Mine die on the highway, and the dealer did not do anything beside from checking the car out for three days. Also call BMW USA and they said that they will look into it, and assure me that the if the dealer release the car to me b/c they have check everything they could. The dealer didn't do anything b/c they can't dup;icate the problem. I'm just waitting for the time bomb to blown and get rear ended, if it happens BMW USA will hear from my lawyer soon.

I understand that random problems can happen to any car. But a problem as widespread as faulty hpfps, that bmw is well aware of, which could cause a serious accident should be fixed. BMW should not be permitted to allow a known problem to persist if a serious life threatening injury could happen.

A faulty pump is annoying and I wasnt really worried about it, but a faulty pump that shuts down the car on the highway is a needless death waiting to happen.

mine stalled on a major highway, I thought I had a flat tire and put the clutch in to down shift and move over to the shoulder and the car stalled power steering locked up, etc. good thing it was at 3am when there was no one on the road.

I don't know what the freeways are like where you're from, but if you've ever been on the Dan Ryan or the others out here, you'd know that it's more difficult than it would seem, with all the traffic, a million lanes wide, merges in from the left and right, and the fact that no one around here would give a shit that you needed to get over.... And, yeah.... I can see how someone would end up assed out in the middle of the freeway, which is a recipe for absolute disaster.

Right before my second pump went out I was chasing down a 550i and I got cut power on the highway then figured I should pull off and turn the car off for a few seconds. Right when I put my blinker on I couldn't keep the RPMs up and it stalled, luckily I was close to the exit so I was able to coast down the offrAmp to safety.

symptoms possible long crank, reduced performance, reduced gas mileage.

nothing like merging onto a heavily congested highway expecting a certain level of performance to fit inbetween two cars only to loose everything at the last second.
recipe for disaster. I too am surprised we havent heard about any accidents,deaths regarding this faulty pump or pump related problem.

It's been at least 2007 that i was aware of this faulty design (pump or electronics around the pump) and it's yet to be resolved. somebody explain to me... er justify to me why a massive company such as bmw, with the pump on many different models now & with 3 years under their belt cant resolve it.

/me notes penny pinchers probably say its easier to pay a lawsuit then replace all the pumps/design.

ppp

After a pump failure, is the car drivable? I know that it goes into limp mode. But will the car drive say back to my house or to safety?

Or does the pump failure disable the car completely?

Some people go into limp mode and can get home, some people's just die altogether.

Its a crapshoot really

You can, but the car runs very poorly and your power is limited.

As long as I can get to safety and am not stranded on some random road then im happy. Makes me feel better at least knowing that I could get home on limp.

BMW would have to really care about something more than the cost of a recall, we can all hope that no one is seriously hurt because of the hpfp FAIL issue

Have you not ever pushed in the clutch and put your car in neutral? Your car coasts and decelerates very slowly. Stop over thinking things. You might as well start worrying about getting hit by lightening too.

I drove to Orlando from NJ last year when my car only had 6k miles on it. I now have 10k miles on it and going to Orlando again. Now i wonder if i should just use my other car. Always worried about the rft - getting stuck in the middle of nowhere and no bmw dealership and now this hpfp prblem....
Is it only on the 2007's ? Has the problm been fixed with the new models ?
