2019 Ram 2500 Vehicle speed control Problems

“Both cruise control and adaptive cruise control fail to maintain a constant speed over flat/level roadways. When cruise control or adaptive cruise control are engaged the vehicle constantly decelerates and accelerates to maintain speed. Vehicle HVAC system is inadequate, blows cool, not cold, blows cooler from passenger side vent impacting operator comfort and increasing fatigue. Additionally, it blows cool air through the defrost panel when it is not needed causing the windshield to fog up.”

“Service ESC flashing on the dash intermittently. If I am in cruise control when it happens vehicle abruptly disables cruise control. Codes when ready are U0002 and U0212. Same problem happened about a year ago, dealer reflashed ABS and sent me on my way. I informed them of other similar trucks experiencing the same issue and that it wasn't a reflash issue.

“While towing a roughly 13k pound camper with my family from Texas to New York and back , I lost trailer brakes, traction control , cruise control and my trailer brakes. The trip included ice, rain, snow. We had a death in the family and the trip did not include the time to take to have this problem troubleshot. Literally one of the scariest trips ever through different elevations and traction levels. These would’ve all been just fine had the systems worked correctly.
