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.

When truck is in cruise control on with driver assist on, if I run off side of road and go over the ridges on the side that alert driver my ABS light comes on saying my driver assist and my cruise control can no longer be used and my ABS breaking system requires a mechanic. If I reset my system all goes back to normal till I go over rough road or ridges. I have less than 10,000 miles on truck. From what I hear from other Dodge owners this is a common occurrence. This has happened on three different occasions.

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. After the dealership changed the ABS module and both batteries the vehicle has been operating ok although I still receive low battery power notices which restricts certain vehicle functions every few days. I have to turn the engine off and on to reset the error.
