Tesla Motors, Inc. is recalling certain model year 2013 Model S vehicles equipped for, and delivered with, certain NEMA 14-50 (240 volt) Universal Mobile Connector (UMC) adapters, according to the National Highway Traffic Safety Administration. During charging, the adapter, cord, or wall outlet could overheat.
An overheated adapter, cord, or wall receptacle, increases the risk of burn injury and/or 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 percent. 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. The manufacturer has not yet provided a notification schedule. Owners may contact Tesla Service Center at 1-877-79-TESLA (1-877-798-3752).
Owners may also contact the National Highway Traffic Safety Administration Vehicle Safety Hotline at 1-888-327-4236 (TTY 1-800-424-9153), or go to www.safercar.gov.
