If you're having trouble steering your car, it's likely due to a problem with your power steering system. Power steering uses hydraulic fluid to assist in turning the wheels, and if there's a leak in the system, it can cause the fluid level to drop, making it harder to turn the wheel. Another possibility is that the power steering pump is failing and not providing enough hydraulic pressure. This can be caused by a belt that has come loose or worn out, or a pump that is leaking fluid. If you suspect your power steering system is malfunctioning, have it checked by a mechanic as soon as possible.
