If your steering wheel locks up while the car is in motion, perhaps the most likely culprit is a lack of power steering fluid, or dirty power steering fluid. Especially at lower speeds like parking lot maneuvers, the power steering system allows you to turn the wheels with ease.
What happens if your steering wheel locks up?
Sometimes your steering wheel locks up as a safety mechanism. Automakers design steering wheels to lock up to prevent unsafe maneuvers, such as sharp turns. Even if this doesn’t cause your wheel to lock up, you could jam the power steering pump or gradually damage your transmission.
