Vehicle wouldn't start, had to jump start it under the hood. 12V battery under rear seat showed sufficient voltage. Took vehicle to dealer and they reproduced and confirmed the conditions. Vehicle is still at the dealership awaiting repair. Suspect faulty soldered terminal in the battery wiring harness. Safety issue if similar faulty soldered joints exist throughout the wiring harness or electrical system causing more catastrophic conditions, i.e. loss of power while driving.

Vehicle can not power on after shutting down. You must jumpstart the vehicle everytime. Dealer stated wiring harness is the issue

- Katy, TX, USA

When turning off the vehicle, all electrical is powered off, and will not turn back on. This includes all door locks and shifting abilities. The vehicle cannot be switched to neutral to be moved without battery power and a manual override.

- Renton, WA, USA

The vehicle lost all electrical power with no response from any of the vehicle systems (i.e., door locks, lights, ignition, etc.).

Drove vehicle, stopped and turned off the vehicle. No lights, no power nothing at all. Jumped vehicle and drove the vehicle home with no issues. I tried to restart the vehicle and nothing at all again. 12 volt battery was tested and found to be in good condition so it was not the battery. I had the vehicle towed to the dealer.

My car goes into deep sleep mode for no reason. The battery is fine, the harness is having issues.

Faulty wire harness, (part # C1617E-1) causing the vehicle to die without warning!

- Merrionette Park, IL, USA

Yesterday I pulled into a gas station and the moment I turned the key off everything went dark. Usually the radio and instrument cluster stay on for a bit until I open the door but not this time. 5 minutes later it finally came back on, after me trying to investigate what's happening. Thought it was a fluke and drove about 45 minutes away to an appointment and got stuck for an hour or two until I could get someone to jump me. Then drove home, turned the key off same thing happened again. The only way to get the vehicle on is to jump it. 12v battery reads 13.6v on my voltmeter, but under the hood near the fusebox it's only reading 3.36v. They are supposed to be the same which means there's an electrical wire harness issue or a loose connection somewhere. Been driving this since Jan with no issues at all. I drive around 2 kids aged 4 and 16 months. Getting stranded over 45 minutes away from my house with 2 kids isn't safe, it could have been worse on a 86 degree day. I've read online forum multiple people having these same issues with this hybrid truck. Picture below with purple circle is where people are stating the issue is from.

Only had my Ford Maverick for 3 weeks and went to start the truck and it was completely dead. Couldn't even use the key fob. It went into Deep Sleep Mode. Had to have it towed to the dealer. Still waiting on it.

Compete electrical failure while driving on highway. Car engine cut off and -??stop safely-?? message came up. Jiggled loose connection on wiring harness positive termination under the hood and everything came back to life and car operated normally. Engine/electrical system failure at highway speed very unsafe- faulty wiring harness needs recall replacement issues.

The entire electrical system failed and couldn-??t be jump started by the Roadside Assistant.

Went into a Walgreens, came out 10min later truck had no power what so ever, had truck jumped, drove to dealership truck was @ the dealership for 1month due to wiring harness on back order.

- Venice, FL, USA

Electrical power harness failed, shutting down all electrical systems. The emergency brake, engine, and instruments immediately ceased to function. The dealer diagnosed a faulty wiring harness and replaced the component, Ford Part# LX6Z-14290-PA. No warning lamps, messages, or other symptoms of the problem were observed before the shut-down.

There is a wiring harness that connects the 12v battery in the hybrid Maverick versions with the components in the engine bay -- dozens of users in one the Maverick Truck Club forum have posted about this wiring harness failing due to a poor solder connection. This has now happened to me as well. In my case, there was no warning, the truck completely went dead after I came back to work from lunch. The entire electrical system, which runs off the 12v battery when you turn off the truck, was 100% dead. The battery was fine, at 12.5v, but the rest of the system couldn't access the battery power, and you couldn't turn the truck on to access the high voltage battery power since that relies on the 12v battery to engage the contactors. I had my truck towed to the dealership and it took them more than a week to get the part replaced. I told them what I knew about the issue and they determined that this wiring harness was indeed the problem. They said there is STILL no official bulletin by Ford and no recall at this time. This part needs to be recalled and fixed so people are not left stranded when it could be easily prevented due to a faulty part. I've attached my dealer's service notes.

Upon turning off the vehicle the electrical power throughout the entire vehicle will fail, leaving vehicle stuck in park, with no ability to move. After this occurs, vehicle will no longer start. If you are able to get vehicle to turn back on (either through jumping or putting pressure on the wire terminal near the underhood battery) the vehicle will die again once turned off. Issue began occuring at 8,000 miles, it has been reproduced at the dealership, and no warning lights alert the issue. Safety at risk due to high probability of being stranded when vehicle does not revive, and a possibility of the issue occuring while driving.

Returning home from vacation. Stopped for lunch. Went back to vehicle and Vehicle was dead. After repeatedly hitting unlock button was able to unlock vehicle. Since I was aware of this potential issue I had a battery booster jump pack in the vehicle...but if you can't unlock the vehicle you are out of luck. Luckily after repeatedly hitting unlock...it eventually unlocked. When I got in I tried to start it but instead got a message saying "No Key Detected". I got my battery pack out and hooked it up...hit boost. Went to start the Mav and instantly it started. When I got ready to go, I could not move the dial from Park to Drive and still was getting the "No Key Detected" message. It took about 2 or 3 minutes for the key to be detected. Drove vehicle to dealership and and am awaiting repairs. Suspect this is a wiring harness issue that have been reported by numerous Maverick owners. Seems like a TSP/Recall is in order! Only have 1,155 miles on this new vehicle.

Purchased new 7-22-2022. On 8-10-2022 drove 14 mi, parked for 2 hours, tried to start truck, message on dash said -??stop safely now -??, with red triangle, check engine, battery warning lights. Tried repeatedly to start truck waiting 15 minutes each time, wouldn-??t start. Used ford pass on phone to call for tow. When tow arrived 30 minutes later the truck started like normal. Drove around parking lot while tow truck waited seemed normal so I drove home. Had dealer check 12v battery on 8-12 and it was fine. Made appointment for diagnostic testing for 8-22. Other owners have received -??stop safely now-?? message while driving on highway, engine lost power and coasted to stop on side of road - obviously a serious safety concern.

Had vehicle towed into shop because it was dead and jumping it couldn't sustain a charge. Dealer took a week to determine it was a DC converter problem and ordered part to replace. After replacement, it was determined it was a battery cable and has been backordered for 2 months. Parking brake error message was present randomly, otherwise no other warnings occurred.

I was driving on the highway at about 70 MPH when the truck gave me a "Powertrain Malfunction/Reduced Power" notification & the red battery light came on. The truck then had a "Pull Over Immediately" (Not 100% sure on the wording) notification on the dashboard and stopped accelerating. Once the notification popped up and the truck stopped accelerating, the air conditioning & power steering also stopped working. I was able to coast long enough to get over to the shoulder where I was able to call a tow truck. While waiting for the tow truck, the truck would not start, the hood latch would not open, and it was unable to shift gears so it could not be put in neutral to be towed.

Loose connection for positive cable on wiring harness under the hood causes intermittent complete failure of electrical system. Car is unable to start when the connection is loose without a jump.
