2025 Ram 1500: won't start

Filed Apr 29, 2026 · Electrical · VA

My vehicle has experience repeated electrical system failures resulting in no-start condition and a loss of reliability. The first incident was in Nov 2025. The vehicle would not start after being parked at work from 0630-1530. The batteries had been drained due to what the dealer identified as a radio frequency module issue. The technician explained it to having gotten "stuck" in update mode. The vehicle was under warranty at the time and required a replacement of the module and two new batteries. I asked what I should look for in case this happens again in hopes of getting it to the dealer before it drains the batteries and I was told there are no real indicators. Early in April, the auto started not working consistently and the FOB would not open the doors. I replaced the battery in the FOB but the issue continued. Since that time I have monitored the voltage gauge. The vehicle was taken to the dealer again mid-April. The tech said he could not get the auto start issue to duplicate, stated there were two software updates that they updated and that it should be good to go. Monday, April 27, 2026 I parked the truck after work with the voltage reading 14.3. Tuesday, April 28, when I attempted to get in the truck to go to work at 0615, the failed to start or respond to the key FOB in any way. Once again, the truck was towed to the dealer where it is currently. The tech has stated they are having to replace the batteries again. This pattern indicates an electrical system failure due to battery drain and repeated no-start conditions. The failures occur without warning and have resulted in the vehicle being inoperable on more than one occasion. This repeated issue presents a safety concern if the vehicle can become stranded unexpectedly due to this failure. The issue does not appear to be resolved. The tech informed me that the company is still trying to figure it out.

Gear shift cluster lights up and flashes dash states service gear shift will not start or go in gear. No codes found. Happened multiple times but never while at dealership. Now the dash cluster keeps randomly going black but never longer than 2 mins so I can't take it to the dealership while it happens. And now the backup camera is randomly flashing blue sometimes instead of showing an image. I have videos of different instances

Check engine light is on and off for the past month. The day before I took it to the dealer the light went off. I went into my vehicle appointment, and the check engine light was off and there were old codes for the fuel temperature. He reset the codes, and the engine light went off. I drove off and obtained fuel the next day and when I filled the tank, the check engine light went back on again. On December 21st, 2025 I drove it to an AutoZone for the free engine code diagnostic tool/test. The code that presents itself is "Fuel Temperature Sensor B Circuit Intermittent". This is the second issue with the vehicles electrical system. The first was two weeks after I bought the vehicle in March 2025 the vehicle would not start. Come to find out, the electronic shifter was wired wrong from the factory and a whole new was ordered and installed. I will have to take it back again to the dealer.

The first major problem was when the truck just didn't start 11/25/2025. The truck was towed to the dealership. The dealership said it was a bad electrical fuse and I picked up the truck. There were no warning lights on before the brake failure. Last week, 12/18/2025 my brakes failed while I was driving my son home from school; thankfully we were in our development and going very slow so we weren't harmed. I was driving like I normally do, and went to brake, and the brakes weren't working, the pedal was to the floor. There was just no resistance with the brakes at that time. All the warning lights in the truck were flashing. After we rolled to a stop in the grass, I turned the truck off. I tried to turn it back on but it wouldn't go on. I waited a few mintues and tried again and it turned on. I was a few houses away from my home so I attempted to drive it again very slowly, and the brakes worked again. The truck got towed to the dealership, and the dealership is saying they can not find anything wrong with the truck now. There must be some kind of major electrical issue going on, but the dealership says they can't find anything wrong.

Date: November 12, 2025 Vehicle: 2025 Ram 1500 Big Horn 3.0 Dealer: Frank Boucher Chrysler Dodge Jeep Ram of Janesville – 4001 Milton Ave, Janesville, WI 53546 I have been experiencing ongoing electrical and instrument cluster failures with my 2025 Ram 1500 Big Horn 3.0 since purchase. The most serious issue is a recurring message: “Warning Light Illumination Cannot Be Shown – Service Required.” This means the cluster cannot guarantee display of safety alerts such as the check engine, airbag, brake, or oil pressure lights. This is a major safety hazard because I may not be warned of a system failure while driving. The truck also shows false “Trailer Light Out” warnings when no trailer is connected, indicating a fault in the Body Control Module (BCM) or CAN bus communication. This may cause incorrect trailer or brake-light behavior, putting other drivers at risk if brake or turn-signal lighting fails to operate properly. It also displays a false “Too Much Oil” warning despite normal levels, and the 3.0 engine has no dipstick, preventing manual verification. The truck has also failed to start multiple times with both the remote fob and manual ignition. On November 12, 2025, it would not start at all; after several attempts, it started with the check engine light briefly on, then it turned off on its own. I have brought the vehicle to the dealer twice. Technicians confirmed Dodge/Stellantis is aware of the defect but said no repair or software update currently exists. The issue has been reproduced and documented. Based on symptoms and dealer feedback, this is likely a BCM or instrument cluster communication fault within the vehicle’s CAN network, affecting ignition, lighting, and safety indicator functions. It directly violates FMVSS 101 (controls and displays) and poses a serious road-safety risk. I request a full the federal safety agency investigation and recall for this defect, as it affects multiple Ram 1500 models and leaves drivers unaware of critical system failures.

Purchased a 2025 Ram 1500 Rebel X ($82k MSRP, fully loaded) in May 2025 for family use and towing horse trailers in remote areas (solo female driver). At ~8,000 miles, it has had repeated electrical failures under warranty, creating safety hazards (shift lock, stranding risks, public safety impact). No Stellantis fix; Q4 2025 software promised. Video of Oct 10 incident available. Timeline: • May 2025: Took delivery. Used for errands, remote towing. • Sept 10, 2025 (~7,500 miles): Truck non-responsive in driveway (no fob/locks/dash/start). Blocked spouse’s SWAT vehicle, delaying emergency response (public safety hazard). Towed to dealer via Stellantis Customer Care. • Sept 11-12, 2025 (Visit #1, 2 days out): ‘Dead battery’ diagnosed; replaced. Issues continued to occur. • Sept 12 - Oct 10, 2025: Electrical issues impaired use: slow Uconnect screens (distraction); stuck radio volume; ‘Illumination Alert Unavailable’ (headlight issues); settings not saving (HUD/seats); locks cycling unprompted; proximity key unreliable (stranding risk). Lost trust for towing. • Oct 10, 2025 (~7,900 miles): In remote pasture after dark, cluster went black (no gauges); engine started but transmission locked in Park (‘D’ flashing). Stranded solo female driver (no cell service; tow inaccessible—severe safety risk). Restarts failed; sat 10 min, self-resolved. Video available. Drove home cautiously. • Oct 11, 2025 - Present Oct 14, 2025 (Visit #2, 10+ days): At dealer for cluster/shift/BCM issues. Prior issues noted. No ETA; no contact since Oct 14. Base-trim loaner inadequate. Electrical faults cause no-start, shift lock, stranding—risking emergencies. SWAT vehicle blockage was a major public safety hazard. No crashes/injuries, but repeated risks for female driver. Request the federal safety agency investigation/recall for 2025 Ram electrical systems.

My 2025 ram 1500 Tradesman pick up with only 600 miles would not start. I called roadside and had the vehicle towed to Wallace Chrysler Jeep Dodge ram dealership in Stuart Florida. Two days later, they called and said the issue was with possibly the starter or the E torque mechanism. Collin from Wallace service calls later to say the truck was ready. I didn’t drive very far for the truck to turn off and put itself in Park. The truck goes back to Wallace. Collin calls the next day to say the truck had a low hybrid battery voltage. At this point I don’t trust the safety of this vehicle.
