NHTSA Complaint #11554333 — 2019 RAM 3500

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.
