On my 2019 RAM 3500, I reported a problem with th eNHSTA back in 2023, and NO response yet. This is about the integrated brake controller, that provides NO electrical signal to stop the towed trailer at speeds what apear to be below 35MPH. This is a very dangerous failure on these trucks.
I had a parasitic draw on my battery that became progressively worse to the point that a jump no longer worked to start the vehicle. I bought a brand new battery and it was completely dead within 24 hours even though I had only driven the vehicle about 5 miles and had the vehicle off for over 23 of these hours. I replaced the battery again and left the vehicle running while loading for a trip and 30 minutes later the battery started to release smoke from overheating. Wires and plastics around the battery were starting to melt so I completely disconnected the battery. This 2nd new battery was also dead within 24 hours of purchase. I took the vehicle to a Ram Dealership and after a lot of testing over multiple days they identified the problem as a parasitic draw from the ABS module. Please note the parasitic draw occurred whether or not the vehicle was turned on. …
Poor throttle respond when doing lane change, really really poor throttle respond, especially when doing lane change the throttle supper slow respond can causing a rear end from the safe on incoming lane changed distance to unsafe distance after the lane changed, this seriously can causing the crash by the rear end from the vehicle on the back. It also happened when merge into freeway when throttle is very important for driver to adjust the speed to make vehicle merge into the traffic smoothly. Reported to dealer service manager everytime drop vehicle for servicing but CAN NOT fix the issue. This happened when the dealer upgraded new calibration for power train by other recall. But before power train upgraded my vehicle dont have this poor throttle respond issue at all.
