Defective Battery, Recall 24S24 and other topics

[SnoopyBroncoSport]

As I understand it the recall procedure is just flashing BCM/PCM via the OBDII ("Driver Link Connector" port and shouldn't have anything to do with the fusebox.

Have you checked that the fuse isn't blown, or if you used a fuse tap, that it isn't loose?

You said "It does have the ODB Power Cable" - if the dashcam is using the OBDII port for power and to be aware of the state of the car (stopped, ignition on but engine not running, engine on) that would have been unplugged to update the BCM/PCM. All you should need to do is plug it back in.

Update: the ODB power cable was unplugged. I didn't plug it back in as I was in a hurry but will do so this weekend. Thanks for the help!!!

I use this one, cost about $13 when I bought it and now is about $16. Not the best display accuracy but I use it for the purpose you stated plus can take a video of the display while starting the vehicle.

This is cool. I keep one a jump starter charged up and ready to go. https://amzn.to/45JNUS9

 

[Dude]

That’s a decent jump starter with a good working temp range (Work Temperature: -20 ℃ ~+60 ℃ / -4℉ ~+140℉).

where I’m at, the vehicles inside temp can exceed 150°F so I’m looking for a product that is spec’d to ~160°F storage temp.

When discussing these lithium jump starters in the past, I've wondered if there are any potential storage spots that are cooler?

Glove box; trunk (N/A for BS of course); under a seat?

I've never measured interior heat at various locations, but I imagine that under a seat is at least a little cooler.

Here's some info (FWIW):
https://www.researchgate.net/publication/259577084_Temperature_variations_inside_a_parked_car_in_hot_and_dry_climates

I couldn't find anything that looks at temperature in various locations inside the vehicle -- other than the above study that mentions:

"Four thermometers are used to measure the temperature at front dash board, rear board, front seat, and rear seat."

Anyway, what I'm getting at is that maybe 140*F is adequate, if stored (say) under a seat.

Last time I checked into the vehicle inside temp, the variance was no more than a few degrees F.

Bummer.

I was hoping there would be some stratification.

Since y'all are talking about jump starters, I'll throw this one in, I keep it in my F350 Platinum 6.7 diesel:

https://www.amazon.com/GOOLOO-GT4000S-Fast-Charging-Portable-SuperSafe/dp/B09M9HQG73

It's rated to start a 10L diesel as well, 100 watt LiPo. Again it's -4 to 140°, but it can warm itself up in extreme cold. It has large clips on the wire. Charges insanely fast at 100w. I keep it in a case in my truck, learned the hard way when both of my truck batteries died in a fueling bay coming back from vacation towing my RV. I had to be pulled out of the bay into the parking lot and spent the night there (thanks to the RV generator) until I could get the truck towed for service. I haven't had to use it since but it's very highly rated.

I'm very interested in a plug in SoC device, thanks for this thread.

Also wouldn't take my BS/BL home from the dealer until they fixed the recall. Guess I learned to think ahead ?

There’s no mention that the Bronco Sport and Maverick battery of any type (AGM or EFB) is defective in this 24S24 Help article from Ford.

Ford Help Article for 24S24:
2021—2024 Bronco Sport SUVs and 2022—2023 Maverick Trucks — Loss of Power Recall
https://www.ford.com/support/how-tos/recall/recalls-and-faqs/24s24-bronco-sport-2021-2024-and-maverick-2022-2023-loss-of-power-recall/

It’s a good article, worth taking time to read it.

Key takeaways from the article include:

“The current software for the Body Control Module and Powertrain Control Module is unable to detect — and thus compensate for — the decreasing performance in the life of a 12-volt battery. This could result in the vehicle unable to restart while using the Auto Start-Stop Technology or stalling while coming to a stop at low speeds.”

“Current software for the Body Control Module and Powertrain Control is unable to detect the decreasing performance over the life of a 12-volt battery.”

“What will the software repair do to fix the issue?
It will improve detection of and compensate for decreasing performance of the 12-volt battery and help maintain vehicle power. It will also notify the driver the battery is near the end of its life cycle.”

It would have been nice of Ford to provide a description of the algorithm used to detect the battery is near the end of its life cycle but no details that I’ve seen have been provided by Ford.

I would like to know why people are having power failures after they have had the recall done. Didn't the reprogramming allow for closer control of the battery state of charge. What is the common denominator for failures after the recall.

Might be just a few people, no way to know how many. Most likely the battery was on its way out anyway

After reading this whole thread I need to get my paper work from the recall to see if battery was tested and compare to paperwork from regular service a month before.
My dealership has a pretty high turnover of technicians IMO.
Hate waiting until Tuesday to find out if just original battery needs replacing, or the starter is fried.

Just happened to my daughter two hours ago, exactly as described by others here. She was stopped at an intersection and then proceeded to go and before she could get through the turn the entire thing stopped. No power at all. Had it towed to the Ford dealership, and has already been told by them "it can't be the recall, as that's 'just a software update'" and they "have no idea what could be happening." So, yea, lots of confidence with them at the moment.

We both have '21 BS's and I had my recall done last week, but she only got notice of the recall yesterday and then it happens today? What are the odds??

I'd be curious to ask a Ford Tech if the 24S24 resets the battery management system forcing it to retrain on the battery. I had extremely weird alternator behavior (voltages below 12V while driving to accessories in the cabin) shortly after the recall, but after driving a little under 100 miles it had gone to normal.

If it is re-training on the battery, if the battery is already diminished from improper charging behavior in the past, maybe the auto start/stop still kicks on when it shouldn't during that phase. The whole point of the recall was to avoid a loss of power, but perhaps if the issues described that motivated the recall in the first place diminished battery lifespan/capacity, it can still happen...

My battery gets to fairly low states of charge in a few days, but battery healthwise, it's fine, typically putting out over 800CCA when it's rated for 700. I am confident a large part of this is that I have an auto start/stop eliminator, so I put far less stress on the battery because my engine doesn't stop at lights/intersections/etc.

Good afternoon, TK. Would you please send over a private message with your daughter's VIN and dealer info so I can look into this battery concern on my end?

The odds are very good and if the dealership installs a new battery (many owners love their AGM battery), performs the battery charging system reset and performs Recall 24S24 then if the issues your daughter experienced does disappear you know it was just a failed battery … and as others mentioned, when the new battery ages, recall 24S24 likely will help the lifespan of the new battery but we already know that eventually when the new battery also begins to fail and isn’t replaced soon enough, recall 24S24 is unlikely to 100% keep the vehicle from dying as your daughter experienced

even the wording in 24s24 does not state the problem is fixed, it states it is better

From the recall 24S24 FAQs:

Frequently Asked Questions:
https://www.ford.com/support/how-tos/recall/recalls-and-faqs/24s24-bronco-sport-2021-2024-and-maverick-2022-2023-loss-of-power-recall/

What is the issue tied to this recall?
A software issue may cause a loss of vehicle power that can result in the vehicle not restarting after an auto start/stop or stalling while coming to a stop at low speeds. A loss of 12-volt accessories like lights, radio, and air conditioning etc. may also occur.

*** Stalling at low speeds indicates that not only is the battery fried, the alternator is not producing enough current at low rpm. Older vehicles could continue to run with the battery removed.

What is the cause of the issue?
Current software for the Body Control Module and Powertrain Control is unable to detect the decreasing performance over the life of a 12-volt battery.

*** So apparently the BCM & PCM are just looking at voltage. A battery can be badly sulfated and still have a 'surface charge' -- making voltage measurements useless.

What is the repair?
Dealers will update the Body Control Module (BCM) and Powertrain Control Module (PCM) calibrations at no charge.

What will the software repair do to fix the issue?
It will improve detection of and compensate for decreasing performance of the 12-volt battery and help maintain vehicle power. It will also notify the driver the battery is near the end of its life cycle.

*** Apparently not so much. It does not seem to be working as described. It is not compensating enough for decreasing performance; it is not maintaining vehicle power -- if what that refers to is boosting the alternator output to compensate for a bad battery; and from what I've read here on the forum, drivers are not being notified that "the battery is near the end of its life cycle."

Seems like a FAIL.

Is there a warning or alert for customers?
No.

*** Yep, that's true.

To be fair, not all BS owners are having problems, but for those who are being left stranded at intersections on busy highways, this is a serious issue.
