2023 Pro4x 114000km

Multiple dash lights on. Diagnosed as rear diff lock sensor. Apparently it is internal in the diff. Never been off road yet, almost all highway. Quoted $1350CAD. Crazy! Also the transfer case input seal is leaking. Unreal how with no hard off-road that these new trucks have issues like this. I have an ‘04 f-150 with 300k+ that hasn’t had issues like this.
