Hello, I have a 2005 Citroen C3. The steering sometimes gets stiff while driving. Sometimes it gets stiff when I first start it. Yesterday I hit a pothole a little too fast. Then the car stopped accelerating and started working, but it seemed like it had stalled. Then the steering got stiff again. After the stiffness, turning the ignition off and on again 2-3 times fixes it. I took it to a steering shop, but it turned out it wasn't related to the steering. Could you help me? Thank you very much.
