What owners say about the power train

Verbatim from NHTSA complaints, newest first
“Transmission issues are a known problem in the 2021 Ram 1500 and have been for a while, with no recalls. Slipping of gear. Delay or jerking into reverse. Putting it in reverse and it telling me to put it into park or it auto-correcting itself into park. While driving twice and going from complete stop after the auto correcting went to pull off & the vehicle did not go into gear the RPM was raised and the truck moved forward but would not go into gear. The smell of transmission fluid and possible coolant seem to be in truck through vent. The Malfunction Indicator light came on. Had a Shop check code said it showed Valve Body. All these are known issues with the transmission and should be recalled as this is very dangerous for driving as it could stop in road, loose power going up hill on interstate and if there are leaks it could cause a fire. There should have been recalls and investigations. Manufacture knows these issues are and have been happening but does not want to spend the money to fix problems. Ignores and hopes warranty will be gone before it happens so it will be on the owner. That is what they did with me.”

“MGU unit failed / car seized in the middle of the road - sent in to be repaired Unsafe to be stuck in the middle of the road, could not even put the car in neutral to push out of the road Known problem that RAM and Stellantis know about and are not placing warnings. We were told by the dealership we were 5,000 in line for a new part and that it would take a year. No warnings, truck ran perfectly before”

“Me and my 2 children and my husband were traveling to Springfield Mo . We had stopped for some snacks at Dollar general . When we all go back in the vehicle . My husband tried to start our truck he was turning the key over and over and it just wasn’t starting . Here it is 95 degrees outside with 2 small children and our truck is our only transportation . So my husband explained to AI what issue we were having and it said an issue with our Powertrain Control Module . The Powertrain Control Module (PCM) is your vehicle's central computer, effectively serving as its brain. It combines the functions of the Engine Control Module (ECM) and Transmission Control Module (TCM) to manage how your car moves, continually monitoring data like fuel-to-air ratios, ignition timing, and gear shifts. Ai explained to us to disconnect our negative terminal to our battery and wait a few minutes and everything would reset . After waiting we were finally able to start our truck . After we got home I called a dodge dealership near me and asked them to look up any recalls on our vehicle and they said none active . This is a safety issue because the last thing I need is to have our only…”

“I am experiencing a severe, life-threatening stalling issue with my 2021 Ram 1500 equipped with the 5.7L HEMI eTorque system. While driving at low speeds through a neighborhood (between 5 and 15 mph), the engine suddenly and cleanly shuts down without any prior warning, sputtering, or illumination of dashboard error lights.As soon as the engine stalls while the vehicle is in motion, the truck's transmission safety system triggers 'AutoPark' and instantly activates the electronic parking brake. This causes the truck to violently slam to a complete stop in the middle of the roadway, locking the rear wheels. After coming to a complete stop, the vehicle can be immediately restarted and will drive normally without storing any diagnostic trouble codes (DTCs).This exact failure mode matches the dangerous behavior outlined in NHTSA Recall 23V-265 (FCA Recall 37A). However, the manufacturer's database lists this recall as 'completed' on my specific VIN. The software update either failed to permanently resolve the issue, or a hardware defect within the eTorque electrical/grounding system is mimicking the safety defect. The sudden, uncommanded braking in active traffic…”

“On 6/9/2010 I was accelerating up a ramp to merge with traffic on Rt146 north . I had reached the top of the ramp and as I viewed the oncoming traffic behind in the mirror I began to shift into the right lane. Suddenly the engine light started flashing, my truck immediately lost power and slowed to 40mph. The truck that had been well behind me was suddenly swerving to avoid my truck . I nearly got rear ended by a truck which would have probably killed my daughter and I.We both were in shock , I pulled over as soon as I could .Does someone need to be killed before action is taken. Safety should prevent incidents like this . Hindsight is no good. I think my kids are precious but Dodge must think their lives are cheap . That was something the engine manufacturer should be held accountable for. The rocker arms and lifters suddenly stopped working in two cylinders because of a fault in those engines known to Dodge. The dealership diagnosed the issue and gave me a quote of $4500-$6000 to repair the extensive damage from that incident. The lady in the service department said I was a victim of the well known Pentastar Tick .I can’t afford it. To add insult they offered…”
