True or False: A drawback to the single belt system in most modern vehicles is that if the belt breaks, multiple critical functions are lost.

The assertion that a drawback to the single belt system in most modern vehicles is that if the belt breaks, multiple critical functions are lost is indeed true. In vehicles equipped with a single serpentine belt, this belt drives several vital components such as the alternator, power steering pump, water pump, and sometimes the air conditioning compressor. If the belt were to break, it could lead to multiple systems failing simultaneously.

For example, without power steering, steering becomes difficult, and without the alternator functioning, the electrical system would not receive power, which could eventually lead to the vehicle stalling. Furthermore, a failure in the water pump might result in the engine overheating. Such a scenario highlights the risk associated with a single belt system, emphasizing the importance of regular maintenance and monitoring of belt condition to prevent total system failure.
