Casting sand or some other factory sludge in the cooling system. Killed my heater core and maybe more
Head gaskets had to be replaced at 25712 miles in july 2017. Currently still losing coolant. Fca tech advisor states there is nothing wrong. Photo attached is from january 5,2018. I have submitted documentation to fca in regards to the ongoing loss.
I was driving on the interstate and the engine just died. I pulled over to the side of the road and restarted the vehicle and when I put it in gear it acted as if it were in neutral. I then shut off the vehicle and restarted it and it drove fine.
Around 8:00 PM on 9 nov 2017 I was driving on a busy highway going approximately 60 - 65 MPH in the far left lane when the check engine light, ABS light, and traction control light came on. Then the vehicle engine shut off. It would not turn back on and I had to slowly coast to the far right lane.
Engine dies when driving. Windshield wipers come on tpm light comes on then engine dies. Sometimes when driving the wipers come on, tpm light, then car slowes but recovers or dies completly. When starting car turn key to start and the starter continues when you let go of key.
