NHTSA Complaint #11625537 — 2018 TESLA MODEL 3

ISSUE: PTC Heater failed at 63,617 miles after 6 years of use WARNING MESSAGE: "Vehicle may not restart" CONTACT: [XXX] [XXX] main contact for owner [XXX] . VIN: [XXX] MAKE: MODEL 3 YEAR: 2018 REPAIR QUOTED: $1,104.18 LINE ITEMS: PTC HEATER DUALZONE(1088218-00-I) HVAC, PTC SERVICEASSY(1107677-00-A) LABOR & DIAGNOSTICS SUMMARY: TESLA Model 3 Electric Vehicle shut down into "Asleep mode" and will not respond (turn back on). Locked out. Will not wake up. Will not respond to software nor car keys. All systems turned off. Will not charge. Will not release charger from charge port. Issue suddenly happened after [XXX] software load (deemed to not be the cause of issue). Dealership diagnostic shows PTC Heater failure which cuts off the battery. Dealership quoted estimated repair (see below). This could have happened while driving causing the vehicle to be uncontrollable, and a major safety issue. Fortunately, my incident happened after I parked the car in the garage. Overnight there was a software install (supposedly not causing the problem). In the morning the vehicle would not turn on. PRECEDENT: There were several small claims filings in Canada for same issue. This was deemed a design flaw, and safety issue. (See [XXX] ) DIAGNOSTICS: On-line debugging is pointing to resistance issue with 1 of the 5 heating elements in the PTC Heater. PTC Heater cuts off supply to PCS which charges the 12V battery when there is an issue with the heater. This allows the 12v battery to drain, and the EV becomes unresponsive.
