The valves, pistons, head gaskets are all affected and malfunctioned. They caused burning of the oil and loss of coolant. I took it to the sister dealership of where I purchased it to track the leak and they stated that it was fixed. Upon picking it up and driving it to my home and then right back to the dealership (apprx 12 miles) the truck was making big enought plumes to where it was making other operators pull over or cough. I was following behind the truck to video record and it was producing so much I could not see and had to close my vents to not cough. Our oil said 65 % but decided to check it and there was barely any oil present. Had it towed to the dealership and after picking it up it was only worse than before. This is a safety issue. An emissions issue also. Thank you.
