We had to bring in a Jeep Cherokee 3 times for repairs (an obvious Lemon) and every time they give us a date to pick up the vehicle, it's never ready for another 2+ weeks. they made us pay for a loaner (the first day). shouldn't this be complimentary since the car will be at their dealership for 2-3 weeks?
