Deep sleep recall on the Hybrid Maverick??

[skinnyboy]

Its taken so long to fix I have a feeling software alone wont do it. Just a feeling. Same for back-up camera issue. Although my camera has worked perfectly on my 23.

The fact the ford chat person had on her screen its a battery issue and nothing more seems telling. Maybe they just put something simple for chat people to use?

ANYONE tells me to drive more I will tell them to st ick it. No OTHER vehicle EVER owned needed this NOR should this hybrid. Friends have had Prius's for over a decade with no such issues.

We changed our '12 Prius battery after 8 years assuming it was due, but it was still working fine. Three friends with '23 and newer Toyota hybrids have all had dead batteries.

Cheers.

I find it interesting how varied our experiences are.

I park outside and I live in Wisconsin. Over the winter, I get the deep sleep notification regularly, but I only drive like six miles most days. Since I remote start from the keyfob in the morning, I don't really have any major issues. I wouldn't notice if the dome light wasn't on getting in.

As soon as the weather stops going below zero every day, everything goes back to normal. It'd be nice if it didn't do this, but it's only been a minor inconvenience (though I do keep a jump pack under the back seat to be safe).

How do you have remote start on keyfob

How do you have remote start on keyfob

I optioned remote start on my 2023 when I ordered it?

(I mean, technically I optioned the XLT Lux package on my 2022 order, but when I rolled over and they took it out of the 2023 Lux package I had them add it back in)

The app depends on cellular technology, and I want to keep this truck for ten years. There's a good chance the cell networks might stop supporting whatever protocol the truck's modem uses before then (or that Ford might stop supporting the app in 10 years) so I was making sure I'll have functional remote start in 2033.

So yeah, I paid for factory keyfob remote start. That's why I have it.

Seems this issue just doesn't get corrected so I will add my experience with my 2022 Maverick Hybrid concerning the battery issue. After close to a year after purchase, the first battery failed with the interior light syndrome. Everything else worked. I purchased a DIeHard battery ($225.00) which lasted around 9 months and then no interior lights started occurring again. Fortunately I took it back since it had a warranty and got a full refund. After reading so much here on this forum I purchased an AGM battery and installed it this past mid-December. So far so good but????? I also removed the Ford App from my phone and keep both remotes in a Faraday case when not in use and always do a double click which locks everything when the truck sits in the garage for an extended time. Oh yes I recharged the other batteries and checked the voltage many times. I always found as the battery starts to fail the sitting voltage is as low as 11.6 or 11.7 which is too low. I even purchased a device which plugs in the cigarette lighter socket which gives the voltage all the times and I quite accurate. When ever replacing the battery I also always reset the BMS. What is interesting is that when driving usually the voltage is around 15.1 and sometimes drops to 14.7 which is more normal for charging the battery than 15.1 So far when turning off the engine the battery reads 12.6-12.7 volts which is perfect. The BIG question is will this battery fail as the others did?? ...and yet I really like the Maverick, just sad so many recalls and also this battery issue.

After hearing about the charging issues I got a voltmeter for the cigarette lighter socket. Yeah, I know, not perfect but it gives me an idea if something is changing. For the last year it's been very steady and no issues.

Has more to do with a constant power draw. I have a simple solution. To hell with computers and software! When the battery gets low or needs a jump use this hand crank generator. You might even hook this up mount to the fender. Crank for 15 minutes every 3 hours while sitting.

So, has anyone had their hybrid not start due to the deep sleep issue?

From what I've seen on this forum, if I understand it correctly, the starter in the hybrid runs off of the hybrid battery (directly? / indirectly through the 12v battery?).

If that's the case, then would letting a hybrid Maverick sit for up to a month without driving it be a problem, at least as far as starting it up goes?

 

[Mark1]

There is no starter and the 12v battery is only used for accessories and computers. The drive battery turns the electric motor which starts it. The drive battery charges the 12v battery. If the 12v battery is dead though, it won't start and need a jump to talk to things.

No alternator as well.

Great explanation. That clarified a number of things. Thanks.

So, back to my other question, has anyone had their hybrid not start due to the deep sleep discharge issue in less than a month without driving it?

The 12v battery has to have enough voltage to run the computer as well as to close the relays to connect the HVB (drive battery) to the dcdc converter which then furnishes power to spin the starter/generator (smaller of the electric motors in transaxle).

Had mine not start after sitting for a day and a half. Battery was at 3v. Charged it and had parts shop do a quick load test, said it was Ok. Ran it for another 8 months or so before replacing it with a new aftermarket. I am guessing this type of failure is what the update is going to address. I believe that under certain conditions an unusual draw is placed on the battery after being shut off.

There is no such thing as a deep sleep discharge issue, just to understand more about it.

If not driven in 14 days, if the SOC% goes below 50, or the resting voltage is stupid low - the system sends one last message to Ford that your Fordpass will get if enabled - that it's going into deep sleep.

Which means disabling the modem. You had to be warned because now no remote functions.

Deep sleep doesn't discharge anything - it stops one known draw.
But, unless like many parasitic draws it's some other system that's actually causing a problem - malfunctioning radio, beserk security system, EGR or other fuel system gets stuck, ect.

Several people have posted detailing their overnight drain - so there was some specific issue and no start by morning.
Other people have detailed their poor battery with poor charging finally giving up and not having enough power the next morning.
Others have reported getting the battery checked and the stats were so bad they were probably on the verge of it being dead and they got new battery.

Most seem to benefit from exactly what deep sleep is trying to do - preserve your battery for another start to happen.

Actually - the 12V system and the battery charging circuit are 2 different things.
While the voltage coming from the DCDC Conv has always been the same between them in the log files I've seen, the amps is totally different.

You can easily have 30A going to the 12V system, and somewhere between 0 and 1A going to the battery.

Usually by the time the Volts has dropped below 15 the battery amps has dropped below 5-6A level.
Closer the V gets to 14.7 or such, the closer the amps is to 1 or below.
Not exactly, but gives an idea.

The power adapter reading is great for seeing that Acc mode voltage 1st thing in the morning - see what direction the battery is going at least.
