That makes these hybrid unusually unique in the context of total braking loss if some "link" in the control regen/braking control system fails. |

Note the sentence in the attached technical description from
Ford that starts, "In the event that the ABS module detects a fault....." Also note that the predicted relative wear of front verses rear pads.......did not really pan out once 40,000 FEHs hit the streets. (I think people just apply the brakes is too many different ways.....than the drivers on the test track do.) |

Please provide documentation, photos, drawings, to support this, or kindly delete your posts. I've not seen any evidence to support this, and my driving experience over the last 5 years and 117,000 miles, in a FEH, ( Note Willard does not own one ) does not support this. I've read most technical articles for this car, and have found no mention of such. |

Is that correct? Willard doesn't own one? Shouldn't that be Willard doesn't own a FEH? This seems to be a trend here, if you don't own a FEH, stay out of here!
You know what John means. You drive a FE with many components that are similar to the FEH and appear to have Ford's service manuals. OTOH, Willard drives a Prius and has no experience with the FE or FEH so he can only speculate or comment on his experience with a completely different animal. The problem comes from Willard's opinions that go contrary to the personal experience of FEH owners and he also makes controversial comments that don't make him popular. The consensus in a lot of forums I frequent (not just this one), is: if you're not a fan, you're not welcome. |

Right, I drive a '09 FE and from what I read here and in FE forums, the FEH has far less problems. The only troubling issue is the intermittent loss of power steering posted by three owners, I believe. |
Re: Brake Failure
My wife has a MM and it's been in the shop for about a month total since she bought it, for transmission leaks. (That's about 6 times.) Looks like they finally might have fixed it tho. We were considering mentioning the "lemon law".

I filed a report with NHTSA on mine. Almost got T-boned making a left-hand turn when it hesitated. I was able to duplicated the Death Lag for the dealer the other day, so now I'm inbetween the dealer and Ford Customer Service. At least I now know what to avoid. Have you ever asked yourself, "Is my foot on the accelerator?" because it's not responding after accelerating, braking but not to a dead stop and trying to accelerate again which also causes it to downshift? That's the Death Lag which is name given to the problem with a different manufacturer. |
