Consumer Description
On August 20th, 2025 at 2:50pm, my eight-month-old infant was trapped inside my Tesla Model Y for approximately 30 minutes due to a critical systems failure. The vehicle experienced an error with the 12V battery that rendered the doors, windows, and trunk completely inoperable, preventing any means of access or escape. My infant was flushed, diaphoretic, and crying while stuck in his car seat with an indoor temperature exceeding 104 degrees fahrenheit. Despite all attempts to override the system, the car remained locked, and the battery dead, and emergency services had to be contacted. Officers from the Santa Barbara Sheriff’s Department, California Highway Patrol, and Montecito Fire Department arrived on scene and, in order to rescue my baby, were forced to smash a window to gain entry. The police officer was advised by a Tesla representative to do so, as he confirmed there would be no way to override the system to open the doors. My baby was found screaming in a pool full of sweat and was carried to an ambulance, where the paramedic warned me of concerning vital signs and advised me to go to the Santa Barbara Cottage Hospital to have his condition assessed and treated, if necessary. I have obtained a copy of the police report (Case No. XXX) and will provide it upon request. Tesla confirmed that this problem with the 12V battery is common, nonetheless we were made to pay for a new window and a battery replacement. There were no warning signs leading up to the shutdown and not notifying us of this system failure and the risk involved is complete negligence on behalf of Tesla.
