Tesla to release over-the-air software update to fix seatbelt chime malfunction on 817k cars

Tesla is rolling out an over-the-air software update to address a seatbelt chime issue that may prevent drivers from knowing they’re unbuckled. The recall covers a total of 817,143 vehicles, including the 2021-2022 Tesla Model S, 2021-2022 Tesla Model X, 2017-2022 Tesla Model 3 and 2020-2022 Tesla Model Y.

A note filed Thursday by the National Highway Traffic Safety Administration (NHTSA) outlined the nature of the seatbelt chime issue. According to the NHSTA safety recall report, a software error may prevent a warning chime from activating even if drivers have not fastened their seat belts. As of January 31, 2022, Tesla is not aware of any warranty claims, field reports, accidents, injuries or deaths related to the condition.

The following describes the nature of the seat belt malfunction problem, as reported in NHTSA Safety recall report.

“FMVSS 208, S7.3(a)-(1), requires the seat belt reminder chime to activate when the vehicle is started (i.e. the driver depresses the brake pedal after entering the vehicle) if the driver’s seat belt is not detected as fastened On certain MY 2021-2022 Model S and Model X vehicles and on all MY Model 3 and Model Y vehicles, a software error may prevent the chime from activating when the vehicle is started under certain circumstances.

“This condition is limited to circumstances where the chime was interrupted during the previous drive cycle and the seat belt was not fastened after this interruption (for example, the driver exited the vehicle during the previous drive cycle while the chime was active and then returned to vehicle, creating a new drive cycle.) This condition does not prevent the seat belt reminder chime from activating when the vehicle exceeds 22 km/h and the driver’s seatbelt is not detected as fastened, nor does the condition affect the reliability and accuracy of the visual seatbelt reminder that accompanies it at all times.

The seatbelt chime issue was originally brought to Tesla’s attention by the South Korean Automotive Testing and Research Institute (KATRI) on January 6, 2022. From January 10 to January 22, 2022, teams from Tesla’s vehicle certification and software have investigated the condition, as well as the extent of the problem. A recall decision was voluntarily made by Tesla on January 25, 2022, although the fix is ​​being rolled out via a free software update, similar to other fixes the company regularly rolls out to its fleet.

It should be noted that a fix for the seatbelt chime issue began rolling out in software update 2021.43.101.1, which was originally introduced to Model 3 and Model Y on January 27, 2022. Tesla Vehicles Model S and Model X affected by the issue began receiving the software update with the seat belt chime fix the following day, January 28, 2022. Similar to the recalls the company recently issued for its vehicles, owners affected by the problem are not required to take any specific actions for their vehicles, except to ensure that their cars are connected to the Internet.

Tesla’s remedy to the seatbelt chime problem can be viewed below.

“A firmware release will correct the software error, so the seat belt reminder chime will reset if interrupted during the chime. Firmware version 2021.43.101.1, which includes this remedy, has been introduced into production of Models 3 and Y on January 27, 2022, and into production of Models S and X on January 28, 2022. Additionally, firmware version 2022.4.5, which includes this remedy, will be rolling out over the air (“OTA ”) on vehicles delivered at the beginning of February 2022.

“No further action is required from owners with vehicles running firmware version 2021.43.101.1 or 2022.4.5 or later. New vehicles will not be delivered to customers without 2021.43.101.1 or 2022.4.5 or later Tesla does not plan to include a statement in the Part 577 Owner Notice regarding prepayment to owners as there is no chargeable repair related to the underlying condition and owners will receive the remedy for free with an OTA firmware release.
