Tesla has started rolling out its 2022.4.5 software update as noticed by @Teslascope, which is expected to fix a seatbelt chimes issue as part of a National Highway Traffic Safety Administration (NHTSA) safety recall.

This 2022.4.5 update is confirmed to be rolling out in Canada and the USA, notes @Teslascope and @TeslaFi.

Last week, Tesla and the NHTSA announced the safety “recall” would address the seatbelt chimes issue, where the latter would not sound at times when drivers were restarting vehicles.

“If the audible seat belt reminder chime does not activate at the start of a new drive cycle and the driver does not notice the accompanying visual seat belt telltale, the driver may not be reminded to buckle their seat belt and may begin operating the vehicle in an unbuckled state, which could increase the risk of injury. Tesla is not aware of any injuries or fatalities related to this condition,” explained the safety risk description from the NHTSA report.

Tesla stated the seatbelt issue would be fixed with an over-the-air software update, promising 2021.43.101.1 and 2022.4.5 we see today.

The automaker said production vehicles already have the fix in place, which applies to 2021-2022 Model S and X units, in addition to 2017-2022 Model 3 units and 2022 Model Y units.

As for 2022.4.5 release notes, according to @greentheonly, “the release notes are same as 2022.2.1,” including all the specific features released in the latter for China, which include a new car colourizer feature.

South Korea’s Automobile Testing and Research Institute discovered the seatbelt issue on January 6; Tesla then investigated the issue and concluded a safety recall was necessary on January 25, to be fixed with an OTA update.
