Battery saver system

[Camr]

I’m having a n issue with a new 2019 3500 with 1400 miles. On a cold start, the truck will start and run just fine. but approx 10 minutes into the drive, the battery saver waring appears on the EVIC and the system sheds some circuits such as the radio, etc. This only happens once per day at the cold start, all other warm start drives are trouble free. To reset the system and get the radio to play, I pull over, shut the truck off, and immediately restart it.
The batteries test good, and the alternator (220 amp) has proper output. The only electrical items that would correlate to 10 minutes after a cold start would possibly be the grid heater cycle stopping, and possibly the supplement cam heater cycle stopping after the coolant warms up.
The truck has been at the dealer for a few days waiting to hear from the engineering department, who don’t appear to be in a rush to help.
Does anyone have an idea as to what could cause this issue?

Sucks when new doesn’t work right. I would be suspicious of the batteries even if they text good. On any of my newer computer riddled trucks I change batteries often. Had 05 ram diesel same batteries for maybe 7 or 8 years and my dads 92 Toyota sits for months on end and always fires up. Try to get your dealer to put in new and tell them if it doesn’t help they can have them back.

How cold (temperature) is your "cold start?" And how long is your daily drive? Any aftermarket accessories sucking juice from the system? The grid heaters do indeed tax the batteries and charging system but if the batteries and alternator check good, and your drive cycles are adequate, you should not be having this load shedding problem, even in places where it's hellishly cold.

Thanks for your reply. The outdoor temps are around 45F. There are no additional loads, accessories, etc on the system. I would assume that the dealer has checked the batteries, alternator output, etc. I put 140k on my 2014 3500, and cold started it down to -18F, so I can tell that something isn’t right with this new truck.
im going to try plugging it in overnight, so that the grid heater will not be called for, and see if that triggers the battery saver. If it runs correctly, then the amperage draw of the grid heater is causing the issue.

The grid heater is triggered via inlet temperture so even if you leave the block heater plugged in all night, the grid heater will still come on if the OAT is cold enough. I'm with GWN in that the batteries are suspect. And I wouldn't assume that the dealer actually load tested them. Otherwise, the warning system itself may have some gremlins.

Ya you mention to a dealer about changing batteries and you would think you were asking for a kidney!! On my Rebel if it sat for more than a few days in the winter then there was no guarantee it would start or even turn over. I just buy my own, it’s a lot easier to change a battery in October than fart around trying to boost in the dark with frozen fingers before coffee so the other half can get to work.

I've been getting this Battery Saver message this week as well. It's a frosty 55 degrees here in the DFW. I get a message on the display that power to some systems may be reduced, but I haven't noticed anything cutting out.

My dealer called today to advise that they have received a reply from engineering. They have been given a plan of attack with items and systems to be checked. I will get back to this thread with the results.
Since my opening post, the sound on the radio quit, and restarted by itself the following day. The loose transmission shift lever is also getting tightened when it goes into the shop tomorrow. The water leaks took two attempts to fix, one from the centre clearance light, and the other from the sun roof. This truck is, by far, the poorest quality vehicle that I have ever owned. And I’m old enough to have purchased domestic vehicles in the ‘70’s when quality was at an all time low and the Japanese imports were killing the American manufacturers by building quality vehicles. Im trying really hard to be an FCA fanboy, as this is my third RAM. I’m very disappointed.

I should add that I am very fortunate to be dealing with a dealer with great customer service.

That can make or break an owner's affair with any vehicle.

Weeks later, I am curious as to whether this was resolved?

The issue appears to have been solved. However, I do not have any info as to what the dealership has done to correct the issue. The last invoice indicated that they were receiving info from “engineering” and would follow up. The loose gear shift lever was corrected by replacing the entire lever. The sporadic radio shutdown was corrected with a new “module”, and one of the two water leaks remain unsolved. All these issues on a truck with an MSRP of over one hundred grand.
On a better note, the engine/transmission haven’t missed a beat, and the truck drives great! When it rains my leg gets wet, but as long as I’m not bright enough to realize what’s happening I’m still RAMs greatest fan boy.....with a wet leg!

Must be frustrating but I gues on the bright side it doesn’t leak on your crotch, that would be embarrassing at the grocery store.

This! Just doesn't seem to phase em...

No it doesn’t, and the more hi tech or computer controlled we go the more issues we’ll have and the more everyone will get brushed aside by the same manufacturers. I don’t own a Tesla but I belong to Tesla’s owners forum, I joined it to get the true scoop on what’s going on with electric vehicles because Elon and the owners are tight lipped about issues these cars have. They want everyone to believe they are perfect and flawless vehicles when in reality they have just as many, if not more, every day gremlins. And just like every other manufacturer, they don’t seem to move fast on any issue until either someone gets hurt, some government agency makes them or they start getting bashed all over social media. In the end of the day these things are nothing more than a computer and as we all know computers need to be constantly updated. Just wait until the days vehicles start getting hacked and they have to start doing security updates and such.

Jeez! Did your truck come with gold inlay or something? I didn't think these things could get anywhere near $100K MSRP. Perhaps I should step out from under the rock I'm apparently under from time-to-time.

Up north on the other side of the wall it’s quite easy to get close or even over six figures, that’s in Canuck dollars of course.

I’m from Canada. Add 35% to any USD transaction. The list was just over 100k. Fortunately for us, when we keel over from the shock of the sticker price, our healthcare system takes over!

I had the same problem yesterday in my 2019 Ram 3500 Aisin. Had an Appointment today at the dealer...the passenger side battery would NOT hold a charge it was a 2 hour process...they replaced it. It appears that FCA got a bad batch of OEM batteries. I ordered the truck new and have had the truck for 9 months it was built 10 months ago, 12,500 miles.
