I took my vehicle to the dealership back in October, October 10th to be exact because the all-wheel drive would not shift out of low. My vehicle sat at the dealership until November 18th for them just to charge me a diagnostic fee and tell me there's nothing wrong with my vehicle. When I'm headed home the same all-wheel drive service light comes on briefly. Now I notice a hard shift going into drive from park, drive to reverse, well as a clicking sound when changing between gears for about 3 to 5 seconds. Sometimes reverse doesn't engage from drive so I have to put it in park then in reverse. What could possibly be the issue that these "professionals" aren't finding.
