NHTSA Complaint #11603818 — 2021 RAM 1500

In my 2021 RAM Ecodiesel, several times while on vacation pulling our trailer up steep grades with semi trucks all around a warning message came on saying “Warning Service Electronic stability Control.” Then, the engine immediately went into what seemed to be a “limp” mode with power severely cut. This posed a safety concern because I had to immediately look for a place to get off the highway because the vehicle was slowing down quickly. I found that when I turned the engine off, it took it out of the “limp” mode. I took it to the RAM dealer in Cortez, Colorado and they said they couldn’t duplicate the problem so just cleared the warning codes. When I got home, I took it to Cole Chrysler in San Luis Obispo and they said they installed software that solved the problem. I did not expect a charge for this, because I thought it should have been like a recall item, but they charged me. I assume the problem is fixed, but won’t find out until my next vacation pulling the trailer in September. Should I have been charged for what appeared to be a factory defect? Thanks,
