2022 TESLA MODEL 3 — ELECTRICAL SYSTEM

Submitted Under 49 CFR §552.3 Request for Defect Investigation & Safety Recall Tesla Model 3 / Model Y: Interior High-Voltage Heater Fire Hazard, Missing Firewall, and Entrapment Due to Electronic Door Failures. My 2022 Tesla Model 3 experienced an interior flash fire caused by a design defect. Tesla placed the high-voltage PTC cabin heater and HV wiring inside the dashboard with no firewall. After a crash, I saw a straight “strip flame” shoot out of the HVAC dash vent, exactly like a gas heater. The fire began INSIDE the dash/HVAC ducting within seconds of impact, not from the battery. This shows an arc-flash failure of the HV heater or wiring inside the cabin. The flame entered the cabin instantly because there is no firewall separating HV components from occupants. During the fire, all electronic door releases failed. Tesla hides the manual front releases and provides NO rear mechanical releases. I was trapped inside a burning cabin and suffered major injuries trying to escape by kicking the rear passenger window before bystander helped me brake out the rear passenger window to get me out. Most people cannot escape this design. This is a dangerous combination of defects: (1) HV heater and wiring located inside the cabin with no firewall; (2) HVAC ducting becomes a flame pathway; (3) Electronic door releases fail during fire/crash; (4) No labeled manual rear-door exits; (5) No backup 12-V actuator power to open doors. Tesla must: relocate the HV heater outsid
