Filled tank with diesel and truck wouldn’t turn back on. We were next to a jiffy lube and they were able to run a scan and it said there was a broken fuel module. There’s only around 60,000 miles on it, it’s 4 years old, and left my son and I stranded.
After taking my truck in for recall fixes. I received a message on my screen saying that I had 94 miles until I was limited to 65 mph. It said check def system. After taking it in the dealership charged me to fix the computer. Known defect yet they charge for it.
