While driving my vehicle on the highway, the steering wheel locked up and it put itself into neutral. The abs system notification and another light was active and my jeep stated my vehicle was going too fast for the gear it was in. The abs breaking system bypassed the nss safety feature in my jeep causing me to go off the road as a I lost all control of the steering in my vehicle. Upon a check by the mechanic, I had faulty wiring in the wiring harness which they cannot replace because the part is no longer made. My jeep is only a 2015. I went off the road because there was poor weather - it was snowing out and my vehicle would not respond to any gear resulting in my turning the vehicle off. My jeep was towed to the dealership for diagnosis. I have not picked up my jeep yet due to the dealership schedule but have attached the communication with them concerning the problems.
While driving shifting gears on its own without my control. Slowed me down on freeway from going 50 mph to 35 mph without me slowing it down as I am driving. I was still pushing gas pedal buy while shift was in normal drive from went from 8 to a 3 without my control so I had to pull over because I could not go any faster at all and was in danger zone on freeway that had up to 70mph driving. Once I parked I turned call completely off and then restarted after a min or so it still did the same thing as I drove causing me to pull over more than 2 times. Very dangerous and was not prepared for something like that on busy and fast place as we all know the freeway/highway is. That could of been a total loss for me and other drivers.
Despite having the EGR replaced under recall the unit still exploded while driving on wed 4 Mar 2026. Fluids were leaking and had indicated issues with the electric shifter. The local dealerships states the egr cooler needs replaced, coolant tank, DPF and oil change (despite just being done the Saturday before). Refusing to acknowledge any connection to previous recall or associated damages. Contacted FCA customer support and ignored my concerns and said just pay the dealer the $6000+.
My car keeps slipping into neutral, not able to go over forty three miles per hour. Will not go into park or drive at times. Electrical issues. This has happened several times two times on the freeway, with one of them and entering the freeway, almost causing an accident.
