The contact owns a 2025 Ram 1500. The contact stated that upon accelerating from a complete stop, the engine revved up, but the vehicle failed to exceed 5 MPH. There was no warning light illuminated. The contact stated that the failure had occurred while in traffic on four occasions.
This vehicle has less than 3,000 miles on it and has been in the shop at least three times for a recurring issue with the transmission "lunging" and "clunking hard upon down shift and upshift (automatic). The electrical system and computer are confused and cause the vehicle to literally stop and not engage in gear while driving!
Transmission has a delay when acceleration. This happens when i start to take off from being at a complete stop or.when i pull into traffic. Took it to dealer and they said they are aware of this issue. They did a relearn to the system but problem is still happening. This happens every day
Truck randomly will go into neutral after being placed in gear and moving. I will place the vehicle in drive to exit my driveway. It has happened twice at the exact same spot/conditions. As I turn out of my driveway and begin to accelerate the truck will tell me to put shifter in park and select gear. The truck places itself in neutral.
I purchased this new vehicle on the morning of Saturday, June 14, 2025. At the time of purchase the vehicle had just 25 miles on it. The drive home from the dealership was about 87 miles. A few miles from home, the truck began to shake violently when the gas pedal was pressed. The engine or transmission light was on.

Common questions
Source: NHTSA complaint database, recalls and manufacturer communicationsAre transmission and drivetrain problems common on the 2025 Ram 1500?
They are documented: NHTSA holds 50 owner complaints naming the transmission and drivetrain on this model year (13% of everything owners filed about it), and 53 manufacturer bulletins are filed under the same heading. Whether it is a problem on one particular car is a diagnosis, not a count, and a count says nothing about how many were sold.
Is there a recall for the transmission and drivetrain on the 2025 Ram 1500?
No recall campaign is filed under this heading for this model year (there are 8 filed under other headings). A bulletin is not a recall: it carries no federal duty to repair for free.
When do transmission and drivetrain problems show up on the 2025 Ram 1500?
Too few of the complaints carry an odometer reading to say. The model year's page shows the mileage curve across every system where it can.
What does NHTSA's "Power Train" heading cover?
The transmission, transfer case, driveshafts, axles and differentials — NHTSA files them under one heading. Owners choose the heading when they file, so it says which area of the vehicle the complaint is about, not which part failed.
