NHTSA Complaint #11676193 — 2015 RAM 2500

While driving down highway 65 mph, abs system activated causing right rear brakes to activate causing vehicle to activate steering control making truck head towards on coming traffic before able to control vehicle to shoulder of roadway. Would like to know if, when, and who and where any previous recall work has been performed to this vehicle, bought at a dealership in Oklahoma with check engine light on, told it was gas cap. Turns out it was not a gas cap, there was programming involved to remove the MIL function of brake system. ECM was sent to a 3rd party vendor and unlocked, afterwards the previous program was unlocked showing disabling of MIL functions for several functions. Vehicle is having issues with electrical radiator fan causing excessive heat in compartment, what was the fix for this by MFG? Was it to just program out the electric fan from coming on at high speed ? Now engine within 20 minutes of idling overheats truck( road construction/wrecks)
