Tesla Motors is recalling more than 29,000 Model S vehicle NEMA 14-50 (240 volt) Universal Mobile Connector (UMC) charging adapters that could overheat and cause a fire.
Tesla will notify owners and provide an “over-the-air” software update. Some owners have already received this update.
This update allows the Model S on board charging system to detect any unexpected fluctuations in the input power or higher resistance connections to the vehicle. If detected, the onboard charging system will automatically reduce the charging current by 25%.
Tesla owners can verify that they have received the updated software (version 5.8.4 or later) by viewing the vehicle’s center information screen. Additionally, Tesla will mail owners a replacement NEMA 14-50 adapter that is equipped with an internal thermal fuse.
Owners may contact Tesla Service Center at 1-877-79-TESLA (1-877-798-3752).
