Maverick Hybrid 12V Battery Dead, Left Stranded

[BlueBlazins]

Posting my experience with my 2023 Maverick Hybrid, have seen others posting here with the same issue.

TLDR: 12V battery was dead after sitting for 2 days, couldn't keep it running after jumpstart, towed to dealership and awaiting diagnosis.

For starters, my truck (2023 Hybrid, built in September 2023, just under 3000 miles on it) was last driven on Friday night for about 45 miles. It sat for about 2 days and when I went to start it on Sunday evening, all electronics were dead. Sure enough, turned the key and nothing. Started it with a jump pack and let run for a little while (engine came on for about 5 minutes), then the truck stalled out and died when the jump pack was disconnected. Right back to dead immediately, no electronics or anything. Measured across the terminals under the hood, only 5V

Monday morning, called Ford roadside service for a tow and the driver tried his jumpstart pack, same thing happened. Had to leave the pack connected and actively discharging while he pulled my Maverick onto the tow truck. It arrived at the dealer yesterday morning (12/4) and sat throughout the day, hasn't been looked at yet. I have access to Ford's internal dealer technician system and I can see that over 50 diagnostic codes flashed Sunday night when I first jumped it, many of them related to SSM 52024 - 12V Battery Voltage Low Or Discharged With DTC U3003:62 Stored In The DC/DC. I can also see warnings for Powertrain System Fault, and 3 alerts for Service Engine Soon (related to PT control module, ABS module, and PT electrical fault for the grill shutters). I have to imagine many of these are just related to the battery being dead and the system resetting. Unfortunatley the dealer hasn't had a chance to diagnose the issue yet, and they have a waiting list for loaner cars (go figure). In the meantime, stranded without a vehicle and wondering if anyone else has had this issue or dealt with these fault codes? I've read that many dealers will just replace the 12V battery.

I'm an engineer but not in the HEV or electronics areas... not sure why vehicle would die after disconnecting jump pack if the engine is running.

Some of the fault codes for the DC/DC converter which the hybrid has in lieu of an alternator will disable the DC/DC converter for that cycle. For instance if the output voltage at the converter is too much higher than the rest-of-system voltage. A somewhat common reason for this is if the fuse for the converter is damaged/blown (the SSM 51598/52024 you mention). It's also possible a deeply discharged battery and jump pack may have drawn down low enough under the load of powering up that the converter disabled and so disconnecting the jump pack removed power. Also possible jump starting (especially if connected improperly) can blow that particular 300A fuse.

if the battery is bad enough it will

excuse my ignorance is the battery a AGM?

 

[Techcar]

It sounds almost like the same problems the 2022s had which is a bad connector under the hood that comes from the 12 volt battery. I was hoping that Ford had fixed this problem but maybe one slip by.

AFAIK, none of the Hybrids has AGM 12v battery.

I would purchase a new high-quality DieHard battery etc. and install it myself in order to get Motorcraft out of your failure equation.. It's not uncommon for a new Motorcraft battery to go TU, it sure did on my 2022 Maverick (and my Raptor, a Platinum Expedition, and my wife's Platinum Explorer over the years). It appears they have an infant mortality issue where they either fail early or last a long time.

good luck

Hi, looks like the problem inthis video.

Hi, looks like the problem inthis video.

A 2023 shouldn't be affected by the bad battery cable terminal solder connection.

So you are 100% sure mexican guys can not leave an eyelet loose any more.

Had the exact same experience. Local dealer was very responsive, Maverick was towed, battery replaced, PCM module reprogrammed, everything ok, sat for weekend and started sending alerts about deep sleep. DEALER is researching a solution, I am manually charging 12 volt if it is not driven for 2 days. Their are Ford service bulletins on this issue on Escape Hybrids with same electrical system as Maverick.

I felt the same way about my 2022, but I tolerated it for as long as possible.

I had a 2.0 XL prior to this Mav, liked it a lot but traded up to this XLT Hybrid for fuel economy reasons. It's unfortunate that this issue makes the hybrid look bad, because in theory it's not related to the HEV system itself but rather an issue with the undersized 12V battery on hybrids.
