Tesla has issued a new recall this week. On Tuesday
it notified the National Highway Traffic Safety Administration that some new Models S and X, as well as potentially any Models 3 or Y, might not sound the required chimes if the vehicle starts and the driver is not buckled up. The problem affects 817,143 vehicles and will be fixed by a software update.
Federal motor vehicle safety standards require that our cars make an annoying noise if they are started by a driver who is not wearing a seat belt.
However, according to
the NHTSA Part 573 Safety Recall Report, if "the chime was interrupted in the preceding drive cycle and the seat belt was not buckled subsequent to that interruption (e.g., the driver exited the vehicle in the preceding drive cycle while the chime was active and later returned to the vehicle, creating a new drive cycle)," then the chime won't sound.
The safety recall report notes that this does not prevent the chime from chiming if the vehicle is traveling faster than 13.7 mph (22 km/h) with an unbuckled driver.
