Despite their advantages, timing belts have a limited lifespan and are subject to wear and tear due to heat, friction, and engine vibrations. Most manufacturers recommend replacing the timing belt every 60,000 to 100,000 miles, depending on the vehicle's make and model. Ignoring this recommendation can lead to catastrophic engine failure, especially in interference engines, where the pistons and valves occupy the same space in the engine block. If the timing belt breaks, the pistons may strike the open valves, resulting in severe engine damage and costly repairs.
