Ruh Roh! No dome lights this morning...

Truck parked in driveway for 5 days. Ticking time-bomb?

Low battery. Truck cuts “non-essentials” to conserve power.

Yep, gonna need to monitor the situation.

Best thing is to trickle charge it up to full, but if you drive it often with longer drive times it may get back above the threshold on its own. I don't think sitting unused uses as much battery as short trips which seems to use more 12v than what gets charged back into the battery. And I am not sure the type of driving matters as much as the drive time since it is DC-to-DC charging from the Hybrid battery.

I have had 'deep sleep' issues all along, with the many short trips I take now that I'm retired. Yesterday I got a message on my phone that my truck went into 'deep sleep' mode, which hasn't happened much since we took a 2400 mile trip in August. Anyway, knock on wood here, even though my truck was in deep sleep mode, this morning when I got in at 6:15am, the dome lights came on. And, what seems to be the case, ever since I put in one of those Kia self dimming mirrors, the dome lights work all the time. Will be monitoring this going forward.

If you don't use Fordpass, turn it off in the infotainement menu along with wifi and auto-updates. Fixed it for me, but it's a trade-off if you're a Fordpass fan.

I have left mine in driveway in "Ready to drive" for about 1.5 hours instead of driving it around. With radio, AC, lights, etc turned off the ice will cycle on about 3 times to charge the HVB in that time. So doesn't use much gas at all.

I got 65 deep sleep mode notices on my 2023 xl....much of what Ford tells us isn't accurate...Wednesday I drove 35 miles of Highway and 35 miles rural... got home, checked battery voltage, 12.6 volts....6 hrs later 11.9 volts....20 hours later 11.10 volts.... have to put 2 amp tender on the battery if I have to use it....I am on the 3 rd battery.... Ford has to acknowledge the problem and fix it....good luck...

As has been written about many times previously, pull the 5a fuse in position 11 of the fuse box found under the glove compartment. That is the Telematics fuse that Ford uses to constantly spy on you, all while draining your battery. Have not had a problem ever since I pulled it weeks ago - all lights come on fine inside and out, etc.

I'm curious...is that a hybrid thing only?

From looking at the Ford specific diagrams of the Maverick, apparently that fuse location is on both the hybrid and the Ecoboost models. But I would think it is more concerning for us hybrid owners due to the ongoing drain on our battery not only from that area, but others as well that the Ecoboost folks might not have to worry about.

Some have posted that a 4 amp multi stage maintainer should be used to be able to trickle charge while the random draws are occuring as well as to handle sulfation and stratification of electrolyte. I use a Noco g5 about every three months for 5-7 days, not necessarily continuously. I am on original 12v in my hybrid at 31 months. The original battery is a 36 month battery, I believe. My wife drove 320 mile trip on Monday and returned on Thursday, with 3 to 4 less than 1 mile trips each day on Tuesday and Wednesday. 12v is showing 12.4v in accessory mode at dash PowerPoint with all possible turned off in morning after sitting all night. 12.4v is about 0.1v less than actual allowing for dash and whatever cannot be turned off. (?).

The car is always connected to the internet. That uses power. The keyfob sensor is always running. That uses power.

This is not the frightening thing you think it is. Especially if you park in an area with bad cell service.

Thanks. The whole spying thing is concerning to me.

Can Ford really not solve this problem? I may have to rethink my order. I am not going to leave a charger on a new vehicle, or even an old one. I don't have a garage and it rains 40-50 inches every year here in Mississippi.

I had this problem on my 2021 RAV4 Hybrid twice the first month I had it and Toyota did a software update and solved it. Of course it took them 2 years to solve it and the dealers did not want to do the update until pushed into it. Those 2 times required me to put a charger on and the system fired up as soon as I turned it on. I started it and went for an hour drive in the country. I have not had the problem after the update. Seems like Ford needs a consult! I also keep a Schumacher jump starter and portable power station in the back for emergencies and keeping my tires aired up. I will definitely be getting another one!
