NHTSA Complaint #11574024 — 2018 TESLA MODEL 3

PTC Heater failed. This is a critical component that helps to maintain the battery's temperature within safe operating range. The only alternative is to replace this PTC Heater. Till the replacement is done, EVs battery may not maintain safe operating temperature range and could cause the car - not drive able. I consider this a significant safety risk. Cabin temperature cannot be maintained as well. Cause for PTC Heater failure is known - "change in temperature" could cause this item to fail per Tesla. i.e. when cold air blows over the heating element. Not sure if enough has been done to fix this from occurring for such a critical component with some hardware or hardware recall for several vehicles on the road. Else these cars must be considered for sales only for few states in the USA which have a stable operating temperature ranges for their PTC heaters to not run into the risk of failure due to big change in temperature.
