Maverick Battery Issue [Very Dangerous on Highway]!

[nicemaverick]

I hate hearing this happen to hybrid owners. So far I've been lucky that this hasn't happened to me with my hybrid. But I will be taking in my hybrid to get an oil change soon. My question is since I'm taking it in for an oil change, should I have them check the battery terminals?

Since you are one of the people who were put in direct danger by this, you just might have standing to be a lead plaintiff on a class action lawsuit over this. You should probably contact your area lawyer/bar legal referral service.

Note that I am not a lawyer, nor do I play one on TV. My advice is simply from an educated guess.

If you win, toss me some.

Understood that you cannot link to another thread showing the same thing that the OP of this thread indicates - that the vehicle lost all power - propulsion and 12V - which is not indicative of the known harness defects. For now, OP is the only report of such an issue. Thanks for confirming.

I've been on this site and posted since i originally ordered my hybrid last October and I clearly remember some posts regarding the engine and power dying on several hybrids while on the road. I'm just confirming that at one time there were several posts to that effect. May not have the exact experience as the one posted today...but nonetheless having an engine cut out and losing electronics will moving is seriously a problem and Ford should be held accountable...

Whatever floats your boat. I'm not obligated to do your research nor finding a tread that matches a posts original words like you want. My whole point is like I've already said, their is an issue in the hybrid mavericks that has caused dangerous situations due to the hybrid cable/wire harness/or whatever you may like to call it that many are blowing of the seriousness of it (IMO) and that Ford needs to take serious and get it corrected (IMO)

Thank You for confirming what I've been trying to related to JSUS, he's apparently taken issue to it all and wants to be defensive and that I'm a liar since I not doing the research to point him to one of the other threads wanting exact words to this post original wording

That's your opinion that your entitled to but it's not mine. And it's only one post of others of the endangerment situation because of the root cause of them all (cable/harness) that is just brushed off by many. Fell free to dig further, you will see if you put in the effort instead of wanting something handed to you on a silver platter without any effort on your part. And before you go on the band wagon that I'm anti hybrid, I'm not, to me it's the best of both worlds, but there's an issue with it in the Maverick that Fords needs to step up to and fix, simple as that, that is my whole point. It's be reported in older and newer builds, yes it has not happened in all, but it very well could.

I must have read his post differently than yours. I didn't read @Jatrax post as dismissing the severity of the problem.

All he was saying is that the OP's reported symptoms didn't match the other reported issues, not that the OP shouldn't be concerned. All the other Mav battery cable issues that I've seen (not that I've taken a comprehensive survey of all the reported issues) the symptom is the Mav has no power after it is turned off. But if you jump at the jumping posts in the engine bay the car will start and operate normally until it is turned off again. That issue is a faulty wiring harness between the 12V battery and the rest of the car. All the resolutions that I've seen appear to be the end of the cable from the 12V battery to the power distribution box in the engine compartment, but to my troubleshooting experience one faulty wiring harness end casts all suspicion on all the others. The OP's issue is much more alarming, but not the same as the others. This issue is unique enough that I doubt anyone knows yet what the OP's root problem is.

FWIW, I do agree that Ford needs to up their quality assurance game and catch (and remedy) these issues before their vehicles leave manufacturing. Waiting for someone to loose a life over these issues is unacceptable.

It is no one's obligation but your own to go down the rabbit hole/wild goose chase to back up what you believe you once saw, but that as far as I know doesn't exist. That's absurd. And now you're getting all hostile, defensive, and antagonistic. Yikes.

That's all I'm saying. OP's issue seems to be a new, unrelated one. One that, if it really happened, does not appear to be the fault of the known 12V wire harness defect. One that is much, much, much more serious than simply not being able to remotely lock/unlock, or to start the vehicle without jumping it.

I think you have me confused with a different poster. The situation as described by the OP is frankly terrifying. No matter how good a driver you are something that unexpected cannot be planned for and can easily cause panic and and accident. I agree it is a serious and potentially deadly situation.

It is not however, typical of other reported issues with the hybrid wiring harness which has been thoroughly explored and described. Lumping this completely different event into the same battery harness issue is doing a disservice to the OP. Again, I remember no other reports of a complete power failure while in motion. That is not to say it didn't happen but I don't remember any and a quick search doesn't find any posts where that occurred and was attributed to the hybrid wiring harness.

So lets treat this as a new, very serious issue until we have a report from the OP that explains what the actual cause was.

I owned a 2005 F150 5.4 (purchased it new) that would go into ”fail safe mode”. At speed the engine would shut off, no power steering, no power brakes. I would shift into neutral, turn off the key, then restart the engine. Did that 3 or 4 times before I brought it back to the dealer. They fixed it at their expense but I never got an explanation or saw a recall.

 

[OleFordGuy]

I’m all in for that, my only focus point is Ford has an issue that could cause harm and needs to correct it in the hybrid mav IMO its related to the cable/harness issue, that’s my theory and I’ll stick with it until the root cause is official

Possible blown main fuse?

Over the weekend my Maverick lost all power while I was driving 65 mph on the interstate!!! The engine cut off and the battery went dead. No power to lights, no brakes, no power steering, no power whatsoever! It was very scary!! I was eventually able to drift the car to the median, but was nearly in an awful accident because I had no brakes. I'm sure I drifted 1/4 to a 1/2 mile. Once over to the side of the road, the car remained without power. The vehicle wouldn't even respond to the key fob. The vehicle has only about 8k miles. I understand from reading other posts that there is an issue with the battery wiring harness. It's unfathomable that Ford would sell a vehicle that could lose all power while in operation. I have had the vehicle towed to a Ford Dealer and have reached out to Ford about the issue

Thank God this won't be an issue for new mavericks. Shame this problem ever existed in the first place, but at least we know what causes it and ford has addressed in on future models.

I'd put odds the electronic throttle body. As Ford was starting to transition to those they would be very buggy. If the position sensor detected a throttle position mismatch the PCM would command a shutdown or limp mode. Had to change a few on our Crown Vics and Escapes at the time.
