Hyundai Getz Gearbox & Transmission Problems
Hyundai Getz 2011: Trouble getting into reverse gear?
I doubt there is anything wrong. When it happens just engage one of the other gears and try reverse again. If it persists and gets worse have your dealer make sure the clutch is fully disengaging.
Hyundai Getz 2003: Gutless reverse gear?
IF IT'S a manual it might be a case of getting the right balance of engine revs and clutch slip. If it's auto it might just be a case of applying the right amount of revs to keep the engine firing. As for the doors, lower the window slightly and the doors will close more easily. The Getz has a small cabin and closing the door compresses the air inside. Lowering the window allows the air to escape as you close the door.
