NHTSA Complaint #11674059 — 2022 RAM 1500

The first issue appeared when I came to a stop at a light. The auto start/stop feature malfunctioned and left my truck dead in the middle of a busy intersection and wouldn’t turn back on right away. Eventually it turned on and I was able to make it home safely. I thought this was a one time thing as the truck then appeared to be working fine after. But then it happened again after that where it wouldn’t restart after the auto start/stop function didn’t restart the engine. When I brought it in to the dealership they diagnosed the problem as a faulty etorque motor and replaced the unit in July, 2023, about a year and a half after I bought the truck brand new. Now 2 years later, the issue is happening again. This time the check engine light came on, then a few minutes later the battery low voltage light came on, all while I was driving at speed on the expressway. The truck never shut off and I was able to make it to my destination safely but I feared the same issue from 2 years ago was happening again. I immediately had the 12v battery replaced under the hood the same day and got an oil change to make sure it wasn’t either of those things triggering the check engine light. The check engine light remained on and so I was able to bring it to the dealership with the battery voltage gauge reading 11.2 at the lowest while on the way. They hooked up the code reader for the check engine light which showed error code: P0A78 - Drive Motor A Inverter Performance, leaving me unable to drive the truck home as it is unsafe to drive at this point for fear the truck would lose power while under way. As it stands, truck is at the dealership awaiting further diagnostics for the same issue that’s been happening since I bought the truck new in December, 2021.
