2025 RAM 1500 Fuelpropulsion System Problems

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...

Bought 2025 Dodge Ram on 9/9/24. Since then I have had it into the shop 10+ times. There is a check engine light that comes on. Engine runs VERY rough and erratic. Had issues driving away from a stop light, chugging, lack of power. Making a left hand turn is taking my life in my hands! Each time at the dealership, they run the codes. P0300 is the primary. They just say its a known issue. Manufacture is working on it. IT HAS BEEN OVER A YEAR NOW!! They have never actually done anything to the vehicle other than run diagnostics and turn off the light. In fact the last time I picked up the vehicle 9/12/25, they didn't even turn off the light. Tech said, "whats the point?" I have elevated this with the manufacture Case94136984. There reply was that its not dangerous and a fix is coming. Have...

I am leasing a 2025 Ram 1500 Bighorn from Stellantis. In the less than a year I have owned this it has been to 2 dealerships over 5 times. I hired Handy Law Offices to file a lemon claim . Stellantis was supposed to respond by May 26 and here it is June 9 and they still refuse to acknowledge the problems. And to top it off, I found a positive wire with a split open covering and Summit Automotive in Fond du Lac Wisconsin refuses to fix it, even though they sold me the truck. In talking to other dealerships, this is a shorting hazard and possible fire, but they said Summit has to fix it. I want to know what legal avenues I have to get rid of this truck. I have learned that more and more of this year truck is also experiencing bad problems that Stellantis...

Engine shutdown at highway speed. Everything ceased to work.

Vehicle was being driven at highway speed at about 0555. There were no warning lights including no battery or low voltage warnings. Suddenly every warning light came on and all systems failed. Engine had stopped and computer had shifted vehicle into neutral. Power steering and power brakes had failed as well. At least one driver side rear tail light went out (I think forward headlights as well but not sure). The vehicle was still coasting at highway speed!!! Engine would not restart. I was extremely lucky to not be in an accident as the vehicle was suddenly essentially undrivable while traveling at a high rate of speed. I was lucky to be able to get it to side of road safely but in different traffic conditions this likely would have caused an accident as it was impossible to increase speed, and extremely difficult to steer or brake. The car is...

The electronic shifter knob was flashing lights and the vehicle did not start. Occurred two days in a row. Display stated “Service Shifter”

At only 1600 miles on the odometer, I took the car in for oil service and ABS recall. Dealer inspected, said I was OK. They then Flashed the EBS module with new firmware. 4 day's later (less then 6 miles since dealer visit and arriving home after a brief 45mph, 6mile trip, the check engine light came on. As I was 2 blocks from my house, proceeded home. Engine was in limp mode. Suddenly the warning chime sounded, all warning lights came on. Stopped, tried to change gear selector to "R", car would not change gear. Could not select any gear, forward, reverse, neutral or park. Warning messages would not stop. Chime occurred about every 2 seconds, messages from "no forward breaking", No ABS, call dealer, no side blind spot, do not shift transmission. Car was on a hill, and would not go into park. Unsure about break's, so had...

Engine light comes on every time I put gas in the capless gas tank. It’s a brand new truck, only put gas in 3 times since owning it and engine light has come on each time, light goes off when gas level reaches around 1/2 a tank. Paid short of $60,000 for the truck should not be happening.
