Tuesday night 940pm . My wife jumps in the vehicle , drives down a dark road when the lights interior and headlights blacked out...
She slowed down but not quick enough. She road the shoulder and then rolled the car down a 50' embankment.
She's banged up , could've killed her ..we would've lost a mother , wife , daughter , sister and a friend. Wth?!

I'm quite sure this is a software problem but; has anyone experienced not being able to turn ON the cruise control? I'm not asking about engaging or setting it. Sometime I cannot get the cruise control to turn ON until the vehicle is over 40 mph. Other times it can be turned ON or OFF in Park. I plan to return to the dealer but I would like to know if this has been a problem to others.

lifters appear to be bleading down.Had same thing with dodge Dakota Revised lifters fixed the problem.
