“The car was stopped in the light, the radiator fan came on, it made a sound and then there was a burning smell. The car overheated and I stopped it to cool down. The radiator fan stopped and the car overheated. I took it to the dealership for review and was told to change the fan and fuses. Checking the recalls I found the NHTSA 19v-818, which matches the specifications of my car and the problem with the engine cooling fan. I await your prompt response to be able to solve my problem with the car.”

“I took the vehicle into a Ram dealer service center because the 'fill def' light and message remained in the evic even though the def was full. The dealer determined that the issue was the EGR cooler, tube and gaskets need replaced. The repair was quoted at $2918.27 (see attachment). Upon researching mopar safety recalls, I came across recall vb1, which pertains to EGR coolers of Ram 1500s with ecodiesel engines needing replaced. I called mopar, and they said vb1 does not apply to my VIN, even though it is the same engine. …”

“2015 Ram Promaster city currently has 715 miles on the odometer. We have owned this vehicle for 3 months, and purchased it new. The problem I'm about to describe has occurred on four (4) separate occasions in the last 3 months. While vehicle is in motion, (has occurred between 25 MPH and 75 MPH) the transmission clunks loudly, and is met with a sudden loss of engine power. Each occurrence forced us to pull vehicle to side of road, (3 occurrences on city streets, 1 occurrence on freeway) turn the engine/ignition off, and start engine again. …”

“My 2015 Promaster 2500 got a p0481 code for a faulty radiator fan. This is consistent with known defects in other makes and models in FCA (fiat chrystler automotive). Most notable is jeep renegade fans (p/n: 623740)”
