2025 RAM 1500 Parasitic Battery Drain

[Gillytickle]

How many reporting this issue leave they key fob in the truck? Curious as I heard this may be causing some of the issues?

My fob is 60' away, I get on my wife for leaving fobs in her cars.

they go by the book or whatever the computer tells them to do, zero critical thinking or actual troubleshooting the cause of the problem

They go by how Stellantis has trained them. Their training is horrible and until they fix that it will only get worse.

I don't think that is it. I believe there is a "time out" period where it stops communicating with the truck. If you leave the fob in there or close to it, the red light will blink for a bit, then stop and not blink anymore.

I have left my key fob on the dash in my truck since the day I bought it (October) and haven't had a problem yet. Knock on wood....

Where do you live? Do you park ourside?
Mind if I stop by and check the drivers door for proper operation?

Got my Ram back from the dealer yesterday, replaced the body control module, everything seems to be back to normal for now.

Here's my experience so far with my 2025 Rebel X: Bought new November 30th, pulled in my driveway after leaving the dealership and get a rear park sensor unavailable, service required. Took it back to the dealership on Monday December 2, told sensor #8 was bad needed to order a new one and it's on backorder, sensor comes in and I return to the dealer on December 23rd, new sensor did not fix it, now need to order a new park sense module, on back order, return in January for the module to be installed, module will not calibrate - took 2 days, got it to calibrate and did not fix the issue, determined to be interior harness, no fix kit available, order new harness, take truck home and park it, next day it is completely dead, no power - towed to dealership, troubleshooting determines both batteries are dead - that took a week. Get truck back, sensors still not working and waiting on the harness - harness comes in - 2 days later dealership tells me they have to remove my entire interior to replace the harness - I am furious at this point, service manager talks with me and informs me 2 pins on the old harness are loose in the connector, I ask why just those 2 can't be replaced, Stellantis agrees and they replace the bad pins and the connector with parts from the new harness - get the truck back - seems to be working - passenger tail light not working - just got a call from the dealership and there is no communication to the tail light - and here we go again. I have an open ticket with FCA who offered zero help, don't care about the inconvenience to me, the safety concerns I have with my truck and for my family driving it. All they have done is offered to get me an appointment at the dealership.

Who are you all contacting at Stellantis? I am willing to go the buyback route or even be compensated in some manner. This is not my first Ram or FCA vehicle, I have owned multiple Jeeps and Rams and have never had one in the shop this much.

Oh boy, my rear sensors say they need service. Took it in for ceramic coating and after the sensors are “need service” Guess I need to bring it in for service.

I'm going through this now, i bought a brand new 2025 Ram Rebel, has about 450 miles and noticed sensors stop working such as the auto door sensor, tps sensor (one tire at a time), key not recognized then finally the lights started flickering inside the cabin. Car wont turn on, some attempts there's clicking from the starter tried to jump myself but no luck, all the jump did was able to get the lights inside the cabin on. Car had a mind of its own wouldn't completely turn off, wouldn't turn on. Been at dealer since March 31, dealer replaced batteries and still failed battery test, the rep said he believes it may be a fuse but I hardly doubt that. Clearly there's an electrical issue with these trucks.

Ive own the truck about 3 weeks with 460 miles and this happens, already getting ready to do a lemon claim. First time buying a new car of the year and great experience (sarcastic). I don't blame the dealer I bought it from, since I think they did a great job and good deal just bad car off the assembly line.

I bought my 2025 RAM 1500 end of August 2024. Several electrical issues.
1. The battery has a parasitic drain (11.4 volts with engine off; 13.8 volts engine running). Haven't started diagnosing yet.
2. At ~1700 miles, three things happened within a few days (1) Notification flashed a few times saying "AEBS (automatic emergency brake system) is deactivated", (2) on Uconnect screen this notification appeared "Uconnect Box Requires Service. Please visit authorized dealer." and (3) front sensors spuriously activated with no objects in its path.

Dealer didn't seem to want to diagnose parasitic drain - said battery is fine. They are replacing front sensors. No answer for the AEBS and Uconnect Box Requires Service notifications.

Anyone else have these issues? Any insights on the issues would be greatly appreciated!

Yes my truck won't start near cell phone towers says key fob won't read also dealer said it might be a low voltage issue

Your 2025 RAM 1500's electrical issues is a potential CAN bus communication problem.. The dealer's replacement of the front sensors may only address one symptom, not the underlying cause...

Everyone who bought a 2025 RAM is a beta tester for Stellantis.
Seems that’s the way it is nowadays. Even mighty Toyota f’ed up their new v6 motor, and that was 2 years ago, still dealing with the after-effects.
