At 75,000 miles I wouldn't expect to have this many issues out of such a nice expensive truck. . . The check engine lights comes on and off and it pleases. When the check engine light is on the remote start doesn't work. The tail lights work when they want to and to fix a tail light just 1 is $800. 00. While driving all types of warnings and lights start coming on in a rapid warning annoyance. I've never hooked a trailer to this truck and it keeps giving me some type of trailer braking system warning. The cruise control works when it wants to. Big issue!!!!! the transmission is slipping!!!!!!!!!!!! when driving it will give a hard jerk as if it's having trouble shifting. Doing this at any speeds, anytime during accelerating. So many issues out of this truck it's to the point we are throwing away a ton of money onthis thing!!!!!.
