At the time of service, I felt good about it. Now, less than one week later, not so good. I once again have the same issue: stuck in 4-WD. (The 1st time:reset and test system - I wasn't surprised to have a repeat failure) (The 2nd time: I expected a solid repair). At less than 50,000 miles, on a 6yr old truck, I'm having a real hard time accepting this.
