NHTSA Complaint #11607656 — 2019 RAM 1500

I am receiving a warning light that reads: Service Shifter, Park sense not available, warning with no display, and the vehicle shifts from drive to neutral with a display message to put the truck in Park then shift to Drive while in motion. My safety is put at risk because when driving I have no warning the vehicle is going to shift itself into neutral and vehicles are driving behind me. I have to make a complete stop because I cannot accelerate in neutral. It has happened twice on a busy street in my city. I took the truck to Sierra RAM and they had the vehicle for 4-days and advised they could not replicate the issue. I drove off and immediately the Service Shifter warning came on. This is my second opinion the first dealer Envision RAM advised it is a software issue causing the warning lights to come on. I called RAM the manufacturer and they said to take it to a different dealership, and I did. NO others have checked the vehicle. I tried for RAM to come to dealership, I had a rep assisting me and they declined. There were warning lights coming on first time in April 2024, and I immediately called Envision RAM and took the truck into service. I drove off and the warning lights continued although I took the vehicle twice to Envision RAM they took my money and said it is fixed and it was not.
