Hybrid Dead

[23grayXLT84]

Longer than that. March 2022 is supposedly when the design was corrected.

Mechanically my July built 2023 so far is OK, but of course only 600 miles on it.
Reading issues others are having (CV joint, dead battery / deep sleep, heat exchanger ? etc) Has me honestly nervous. Anyone who will make the argument that is a $25k truck....needs a reality check and if they have money to burn, I'll gladly send them my Venmo info.

First year issues are somewhat to be expected (to a certain point).
Hope a lot of these issues will be no issues in my July built model.

I searched and found plenty of deep sleep posts, many no-start posts, but NO posts involving total power loss.
Look, I received that CSP 22B39 letter 3 weeks ago, brought the Mav to the dealer. They asked me if I ever had a no-start and I answered no. They then said that there was nothing they/Ford would/could do if the no-start problem had never occurred. And they sent me on my unmerry way. This only added to the mystery and my anger when the total power loss finally happened.

It happened to me twice. once at gas station when refueling. called for a jump. made it 150 miles and lost all power again going 70 mph on I-95. scared the shorts off me. towed to dealer. replaced wire harness and 12-volt battery under seat.

I had total power loss many times, cold and dark, but never while underway. That's a whole other level of hazard that should be addressed with a recall. Cheap bastards.

Pro tip to avoid towing

In case it hasn’t been said, if this happens to you, pop the hood (2 pulls) pit 12v on the jumper terminal (B+) and a chassis ground. Don’t waste your time on the battery under the back seat.

You’ll hear some clicking as you energize some modules. You can then turn the truck on inside the caband drive normally. Probably right to the dealer.

Is there a way to check which recalls have already been addressed/fixed by Ford prior to me receiving the mav?

That's scary as F***. Pleast report this to the NTSB. Maybe if they hear about enough incidents like this, they'll force Ford into a recall.

Nothing. Dead.

Hope the problem is solved for you by now. You did say to the reply from a member

Nothing. Dead.

You did say nothing on the maverick is working. all power has disappeared. Nil.
The members reply above mentioned to check the fuse. You responded though and said
'nothing is dead".

Member MakinDoForNow asked: "Nothing when just accessory turned on?" I answered. "Nothing. Dead." I did not say "Nothing is dead." You follow?
Anyway, it was towed to the dealer. They waited 3 days for the recall parts to arrive. Got it back on day 4. Been starting fine, with all power-needy things working. Fingers crossed.

The 'losing all 12V power while driving' scenario sounds more like the bad DC-DC converter 300A fuse. When the DC-DC converter detects its output voltage is sufficiently different from the 12V system it disables itself.

The DCDC monitors the 12-volt battery system voltage internally at the B+ terminal and at the low voltage connector in the DCDC and compares the voltage. If the voltage difference is greater than 4.3 volts, the DCDC sets DTC U3003:62. The DCDC goes to standby mode ( DCDC disabled) and the 12-volt battery can eventually be discharged.
Reduced or no functionality of 12-volt systems (such as the headlamps and HVAC blower motor) may also be noticed.

Or, looking at Mikecando's posts, it sounds like their culprit was the low voltage connector on the DC-DC converter had a poor connection after 12V batt/cable repair. It's possible that was the instigating fault all along and not introduced during the 12V battery cable replacement.

Anything after May 13th of 22 should not be effected by this issue.

Do you know where's the best place to check my truck's build date?

The service department at my Ford dealer told me the exact build date. I believe the sticker on your door has the build month and year.

My Window sticker had the build week 1-9-23. Ford email on 1-18 said it was built.

thanks for reply. did they ever give you understanding about the problem?

Yes. A faulty battery wiring harness. My work order read: "Complete campaign 22b39 Maverick no-start condition. Routed new wiring harness through the clutch port to the 12v battery per FSA 22b29."
