Is there a known solution to Maverick Hybrids Losing Drive Train/Engine Power?

[Joseaoe1]

Can anyone who has had this problem state what was determined to have caused the problem and what fixed it?
FORD, do you know?

I have read through two recent threads and not clear if there is a known defect and a known solution.

ALSO--if there is not already a known cause and solution--then, FORD corporate needs to be directly engaged with ANY service center where a vehicle is being brought in for service that has experienced these issues. That way each of us can contribute to determining the actual cause and solution. And we will know that corporate has been involved in certifying any diagnosis and repair.

Summary: The defect is that while under normal driving conditions Hybrid Maverick loses power. Random loss at any speed and any driving conditions. Various error lights flash when normal drive train power fails. Vehicle may accelerate to low speeds autonomously after restarting. The condition clears and allows normal operation after waiting an indeterminate amount of time or after a certain number of restarts.

In the meantime, I got one of these in the mail today. Shark attack in full effect!

I'm having Powertrain Malfunction and Reduced Power issues, but I have not found a solution. I'm not sure if there is a one fix solution, some threads show it was a battery connector issue, or just a bad battery, or a software fix, etc. I'm still trying to figure it out.

The dealership I bought it from wasn't really interested in helping me. The salesperson I bought from had to really push to get the service department to look at it. however the service manager who scanned it, blamed it on a low battery and said I just need to drive it more. I've taken to another dealership service center and the service manager was the same way, it's just a battery thing. However he also found the gear selector solenoid is throwing error codes, he thinks it bad and draining the battery when in its park when it should be in sleep mode. I'm scheduled to have it replaced this Monday.

However that does not explain the loss of power while driving or the other warnings I get. Its really difficult to record what's happening when troubles arise and you're just trying to remain calm and react safely without causing an accident.

Today I had another limp mode issue similar to the other people in this forum. It caught me off guard because the first one was no big deal, small loss of power but I was able to recover by restarting the vehicle. Not today, I had to restart a few times and each time was more nerve wracking. Second restart, it accelerated on its own, and I had to ride the brake to a stop. Third restart I let it sit awhile longer, and it stuck in slow mode, it wouldn't go above 20 mph? I shut it off and let it sit a little longer and restarted, I finally regained control. The engine light is still on.

Here's one pic from today I managed to take.

I have seen some reference here to people saying something was released in late March to fix the “loss of power” issue, but nothing concrete enough to pinpoint to a specific Ford-released memo/update/patch/recall of it’s own.

The symptoms are serious enough that this deserves it’s own recall notice sent out to owners. When a vehicle STOPS moving because you tried stepping ON the gas pedal, and the vehicle LAUNCHES when you take your food OFF the pedal—that’s pretty F’d up!

ford just issued a recall this week for the issue.

If the issue started after one of the recalls involving PCM reprogramming (Feb thru Mid-March), then re-updating the PCM software to latest configuration should be the solution.

If you haven't already done so, file a report with NHTSA. Have your VIN handy.

Sometimes the big CEO's need a jab in the ass to get their attention. When the lawyers start talking $million$ law suit, they tend to at least come out of their coma and look around.

I don't know that this loss of power thing is a thing with one cause. It seems to me it a lot of problems could cause the truck to go into a limp in mode kind of thing. It's the trucks way of trying to save itself and the driver.
Of course causing it to accelerate by itself isn't helping, I get that. lol
Mine went into a limp in mode when my battery was VERY low, right after I jumped it.
Just take it in for service and hopefully they can read codes, check it over, and fix it.

Hey Jose,

I am having the same problems. The recent recall that was released on power issues relates to no electrical at all. Our issue is loss of power with the myriad of warnings on dash. I have had to bring it in twice to dealer and they have no clue as they can't replicate it and no codes are left for them to diagnose. All I know is that I never had any issues besides the grabby brakes until the emission and taillight recall service.

Thank you. Exactly the same scenario with me. No issues in 14 months and 19K miles until about a month after the recent recalls. Perhaps my brakes were grabby or slight shudder sometime in the past but nothing concerning previously.

in the navy we say that with two points you can fare a bearing. More points lead to better accuracy. I think we have more than two points that direct us towards some element of the recent software recall that led to an increase in these problems.

If I take it for service to a random dealership I have no confidence that the root cause will be discovered and fixed. We need to see something from Ford corporate.

Would be interested in anyone who has a confirmed fix and what the dealer advised was the root cause.

Guys, there has been a big recall announcement about this for several days. You can google about it. Last software developed during the last week of March appears to address this issue. My VIN# and year built isn't in this recall. But please google this for all the info. There are like 4 threads in here about it but you will get a quicker answer googling it.

Thanks. I saw that and thought I read in other recent similar threads--threads regarding the problems that we are experiencing--that this recall notice was unrelated. That is why I began this thread.

Well I do not plan to take my vehicle to the dealer until this recall begins or unless the dealer tells me that they are able to apply the fix that the recall directs.

Those who don't think it is the same issue don't think it is. But from a safety standpoint, wouldn't it be prudent to take it in and have them do the recalls? Just looking out for you. It can't hurt, and it certainly is better than the risk not to. Just looking out for you.
