had the commander in for 4 days for trans. service and serv. 4 wd system light coming on. they talked to chrysler and got a module, they said it was a computer problem and that it was wanting to go into 4wd. Wellll, got the car back yesterday, guess what? - same problem - serv. light came on and it still won't go into R sporatically. I think the next step, since it has been in 4 times for the same issue, is returning the vehicle as a lemon. Anyone been in this position and have any helpful hints. I love the car, and I still want to stay with it, maybe an 07 has the bugs out. ????
