My 2024 RAM 2500 Hemi randomly won't start

[Scubaz66]

So in fairness, after the second appearance of this problem, I took the truck to the dealer and they noted there were about “30 battery related codes.” They fully charged the battery and sent me on my way. I have not had one issue since.

ANYONE ELSE HAVING MAJOR BATTERY ISSUES WITH THESE NEWER RAM TRUCKS???

If the dealer had to fully charge your battery, that tells me your alternator isn't functioning properly. Isn't that what the alternator is for? To keep your battery charged? I'm on my third battery in my 2022 with 33K miles (should still be on my first battery). In Sept 23 truck wouldn't start without a jump start. I took it to the dealer and they replaced the battery with a new 3 year battery. I asked what caused the battery to die and they stated they had no way of identifying the cause. A couple days ago myself, my young daughter and my pup were stranded back in the woods on a trail. I called RAM Customer Service for assistance, too make a long story short (1.5 hours on the phone being transferred from one country to another and finally reaching an English speaking individual in Tucson AZ) I was told there is NOTHING RAM could do to assist me. Luckily I have Roadside Assistance with my Insurance Company.

The following day Dec 2025 I contacted the same dealership asking if the battery was under warranty or prorated. They stated it was under warranty and would be replace free of charge if it was found to be faulty. They would replace it with a 2 year or 3 year maintenance free battery. I ask about a 4-5 year maintenance free battery and was told that wasn't possible. What got me, was the fact the maintenance manager stated the battery would be put on a special test system that took 3-4 hours to complete. (2-3 hours???) I would also have to pay a diagnosis fee should the battery test OK.

$75-$125 diagnosis fee plus 80 mile RT to the dealer getting 10 miles to the gallon plus my 3-5 hours lost wages ($32 per hour) time made it simple to me to just have a local shop replace the battery. It cost me less than $180 to have a 4 year Maintenance Free AGM Platinum Battery installed.

My though process is one of three things are causing battery problems in the newer RAM trucks. Either RAM has purchased millions of potentially bad batteries that don't last more than a couple years OR these newer trucks have numerous electrical issues that cause the batteries to go bad OR the alternators installed are not keeping the battery fully charged. My guess is ELECTRICAL ISSUES!!!

I have a 2024 RAM 2500 purchased November 2024. Currently 34,000 miles. Started having starting issues last couple weeks. Go to start truck on a Saturday morning, wont turn over but dash lights, gauges, radio, etc. all work. Jump it and it starts. Drove fine and charging normally for 50-mile drive. That evening we are 50-miles from home and after an event at 130am truck again wont start. Took multiple tries at jumping and it finally starts. Nothing for 3-weeks. This past Saturday morning wont start again, all gauges etc. work. Change battery and install new battery. Nothing. Sunday morning same thing, nothing. Had it towed to dealership.

Did you seat the fuses in the fuse box when you took possession of the truck? Fuse #F07 is the fuse that allows power to the Starter Solenoid. Open the Fuse Box cover in front of the battery, it's on the left side of the box. It seemed to help with my starting problems. Regardless, It can't hurt to try. I attached a picture of where the fuse is located on my 2022 RAM 2500 Big Horn 4.6L. Your 2024 may be different, so check your panel information. In My Humble Opinion, I'd seat every fuse in the fuse box. This may account for all the temporary electrical issues everyone is having throughout their truck. Remember! Metal shrinks when it gets cold so you may be losing contact where the fuse seat.

I'd Be very curious as to what the dealer finds. Please keep us forum readers informed. Thanks

So dealer just called and truck repair is complete. Starter was bad and needed replacing as well as the starter was shorting out and also caused a fuse/relay to burn up and needed replacing.

Thanks for the update! Much appreciated! I've not had additional starting problems since I seated the Starter Relay Fuse. It's been in the teens overnight and in the low 30's during the day. Battery capacity was down about 78% with 12.7 Volts after sitting about 60 hours, but it started right up this morning and the battery was fully charge after driving about 20 miles. Shut it down for about 30 minutes and it started again with zero issues.

I've been complaining about problems with my truck since day one when I took delivery. So far RAM CARES refuses to help!! My Truck just turned 34K miles but, RAM won't warranty anything because I'm over the 36 month period. Hey! I'm retired and no longer must drive 100 miles daily to work so I'm being penalized. This is my first Chrysler, RAM, Jeep product and It will be my LAST. I've always owned Fords or Chevrolet trucks and other than normal maintenance were never in the shop for repairs. My last vehicle was a 2004 Avalanche I purchased new in 2004. 18 years later I sold it to purchase this RAM 2500. It had 147K on it and had never seen a Service Department. RAM builds a great looking truck and It looks great in my driveway, but I'm going to have to purchase me a Ford or Chevy if I need dependable transportation.

I'm assuming you actually reached out "NOT TO HELP" but to try to "SELL" me an extended maintenance plan?

Well Hannah at RAM CARES, it's now been a week since I took the time to send you the "Direct Message" you requested regarding my issues. As of today I have heard nothing from RAM CARES! Of course at the moment I'm iced in and cannot get my truck off the hill where I live. However, since I haven't been able to drive the truck for a week my battery is now completely dead. Unfortunately this 70 year old man cannot depend on this RAM 2500 he spent over 60K to acquire. Care to Update Me????

They replied to me pretty quickly. You sure they didn’t reach out and the message is somehow deleted or missed?

Well, I guess anything is possible.... I have ask if they are going to reply to my Direct Message, but still have heard anything back. Given my luck with RAM CARES, it's the reason I originally stated I wasn't interested in going that route, BUT as you can read, Hannah from RAM CARES returned a comment, stating it was my choice and they couldn't help me if I wasn't going to provide them the needed information. Against my better judgement, I chose to provide Hannah at RAM CARES with the information she requested. I'll go back to my original Post and see if I can once again get their attention......

Sent you a Direct Message over a week ago, but have heard nothing further from RAM CARES. This is the reason I was reluctant to involve RAM CARES in the first place. However, in good faith on my part, (The Customer) I've included my "Direct Message" to you here as well. See Below a copy of the Direct Message I sent:

See Below, Letter I mailed RAM CARES back in March 2025. Currently I must drive my truck daily to keep the battery charged and carry a Jump Box so I don't get stranded again in icy weather. I quit using my local RAM dealer because they could never find the solution to the TPMS and the Maintenance Team isn't user friendly. Mark Porter RAM in Pomeroy, OH is the dealership that replaced the battery without diagnosing the reason the battery was being drained. This go around Mark Porter states they can test the battery using RAMS battery tester which could take as long as 4-5 hours or even days, but couldn't do it under warranty. Given the cost of a Shop Diagnose and a 60 mile RT to the dealer it was much quicker and cheaper to have a 4 year AGM battery replaced locally.

RE: VIN Number 3C6UR5DJ9NG178278 (RAM 2500 Big Horn)

Ram Customer Care,

I compose this letter as verified evidence I’ve contacted your corporation concerning the below enduring dilemma concomitant with the above stated VIN. A copy of this letter will be mailed to my local attorney assuming I need to hire one as a resolution to the dispute.

Since January 2022, when I took ownership of my new ordered Ram 2500 Big Horn I’ve had issues with the TPMS as well as copious malfunctions regarding the UConnect System.

First 11 months the TPMS functioned faultlessly. In November the TMPS alerted me to a low PSI in a rear tire. I stopped at a nearby rest area to check my tires. My gauges acknowledged the tire had the proper PSI. Since I didn’t really have an issue I continued my trip until I returned home.

The dealer over-inflated all four tires to reset the TPMS then lowered the PSI to manufactures recommendation. The system malfunctioned again within a week. I revisited and queried if maybe the tire sensors or UConnect System was malfunctioning. Dealer affirmed it wasn’t the Tire Sensors.

Dealer contacted their RAM Support Team and was informed wait for an Over-The-Air update. After months waiting for updates and the TPMS constantly malfunctioning I entreated the dealer to contact their RAM Support Team and request a new (UConnect Module) as a fix for the dilemma. Per the dealer RAM Support Team stated they Will Not” afford a new UConnect Module.

The UConnect System is faulty because along with the TPMS, the system occasionally changes radio stations, or other settings exclusive of user contact. I believe there is a short in the system. My truck sat for three days and the battery failed. I took the truck to a dealer to be diagnosed. Dealer replaced the battery under warranty. I ask why the battery died and they stated they didn’t know. Instead of actually diagnosing the dilemma I believe they took the easy route and just replaced battery.

I’m formally demanding RAM resolve the issue immediately. You monitor my truck without permission, know when an Oil Change is due, Mileage, and the TPMS malfunctions. You know what dealer I use for service. Please contact this dealer and have them revamp the issue. I’m tired of entreating repairs and getting nowhere. Cell Number 210-740-7335 or email at [email protected].

I’d say they need to step it up and follow thru.

Well Hannah, It's now been two weeks since I sent you a DM as you requested. Still, I hear nothing from RAM CARES! I know you monitor the forum so there is no reason for you to not reply, when you yourself ask me to provide you the information. WHY!!!
