Wondering if anyone else has experienced total engine failure with the 2018 1500 AT4? Mine happened at 58,000 miles so my warranty covered a full engine replacement. No explanation. I was testing the top speed and when I hit 98mph everything shut down as if the engine had shut off. I was on the highway and had to pull over & wait for a tow truck. I really like this truck 6.2L and the power is obviously on the low end with a top speed of 98… but curious if anyone else has had this issue.
