Heavy Steering at Low Speed
The steering feels heavy or stiff primarily at low speeds, which often indicates a power steering system issue. This could be due to low power steering fluid, a failing pump, or an electric power steering (EPS) fault. Since the 2020 RAV4 uses electric power steering, the problem may be related to the EPS motor, control module, or a binding steering column component.
