Interesting, so far all the hybrid battery issues I've seen have been with the connection I circled in purple, mine included.

I've had no issues since putting a clamp there as described in the Hybrid Battery Clamp thread.

Can you please post a picture of yours with the clamp on? Thanks!

I wrapped electrical tape around it and don't want to mess with it again, but basically identical to skinnyboy's pic from his thread.

My XL Hybrid died today as well. I had to move it out the way of another car and when I parked back in my driveway and turned it off I couldn't lock the doors or start it again. I am waiting for the Ford service department to return my car.

Good luck with that! I have been without my hybrid since July 1 waiting on the wiring from the supplier.

You were right Gullzway. Dealership repaired the cable that everyone is mentioning in these threads. I must have been bumping it when messing with that plug next to it.
Also got the fire recall done while it was there. I'm happy with the dealer that I got it back in about a week.

Found this on FB. Recently repaired dead hybrid. If this is yours, I hope you don’t mind it being shared.

Thanks so much. I sent this to my Ford Service Dept and they said this helped them a lot in diagnosing and repairing the cable.

You’re welcome. Sorry you needed it but glad it helped to get it fixed.

In dealership shop on 7-01, received word from Ford that wiring harness was shipped on 7-22, but dealer has not yet received. The supplier received 75 of the harnesses, Ford part number LX6Z 14290PA in the shipment, so if you are awaiting a harness they are no longer on back order- they are "OBO" Off Back Order. Dang I miss my Maverick!!

FYI, Ford Motor Co Customer Experience Service number is 800-392-3673. Be sure your dealer has ordered the part under "COVIS" so that it is priority to the dealer.

Hi Cactus-Maverick, glad it was a relatively quick experience. Any chance you could post a picture of the repaired cable?

Cheers.

For mine it’s definitely the cable directly behind the one @Gullzway clamped. I suspect that’s the case everywhere. That one was crimped on and rock solid. The one with issues is significantly harder to access. Many people are probably jiggling the one in front and moving the actual problem one enough to make a connection again. Maybe different harnesses have different issues…let’s hope not

I would but they wrapped it up tight with electrical tape. I'd have to disconnect it and unwrap it to see what they did; at this point I'm happy it's working and don't want to mess with it.
They said it originally used conductive glue, so they soldered it and put a bolt through it to make a solid connection.

Day 31 - Replacement Harness arrived at Dealer and Installed. Problem apparently solved. Service Report attached.

Day 8 - Dealer Diagnosis Today (5/30/2022): Faulty Electrical Harness. The cable between the 12V battery and relay was defective. The replacement harness is on backorder, possibly 3-4 weeks. Thank goodness that they found the short and I do not have to live with chargers, jumpers, and uncertainty. I hope that this helps others who have, or may, experienced the problem. I had no warning signs, deep sleep messages, etc. (see below). Hybrid, built 12/22/2021.

Day 4 - Ford Service Update, Gullo Ford, Conroe, TX. Service Advisor, Dean Wachner, called today to let me know that they are perplexed and continuing to research the problem, They have opened a ticket with Ford for assistance. Battery, Alternator, and everything checks ok, but 12V battery is immediately drained when car is turned off. They are also still "working" on a loaner car.

History: Hybrid Lariat - 5 months and 4500 miles of flawless performance. No "Deep Sleep" messages or any type of warnings. May 22, I drove 10 miles, parked for 15 minutes, got back in it and it was as dead as a door nail. Never a problem of any kind before. From reading this Forum, I told myself, "Aw s!*t, Dead Maverick!". Knowing what lay ahead, and being totally pissed and extremely disappointed, I called Ford Roadside Assistance to begin the process. He jump started it with a booster, but after I turned it off, it was again completely dead. He jumped it again, and I headed straight to the Ford Dealer and parked it in the Service Lane. After driving 20 miles, it was completely dead again. May 23, I called the Ford Service Advisor, who said that the battery looked ok, and they were checking everything else for Hybrid problem possibilities.

Good stuff. I have always been knowledgeable about my vehicles and appreciate real world info on them.

My Maverick has been at the deal since June 1st with the cable problem. Reported the complaint to the NHTSA. Communication has been wanting, and they had no idea there was a recall for the Maverick for an oil leak. Part is said to be on back order still per the dealership. I have not been happy with the dealer I have been going through to get this resolved.

Two months without my truck - they loaned me an F150 Sport, but gets less than half the MPG than my Maverick Hybrid. Love the truck, hate that it is a giant paperweight.
