Today my wife is driving the Suburban when she notices that the E-brake light is on. She checks and it is not engaged. Then she sees that the seat belt light is on (everyone buckled in) and shows that it is in Park while she is driving. Later she is driving (forward) while it shows reverse.
Anyone know what's going on? We are going on a few hundred mile trip later this week and she is freeking out about the Suburban acting up.
