A vehicle that fails to make sufficient sound may result in pedestrians being unaware of an approaching vehicle, increasing the risk of injury.

The pedestrian alert sound system may not produce sound at a sufficient volume. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard (FMVSS) number 141, "Minimum Sound Requirements for Hybrid and Electric Vehicles."
