NHTSA Complaint #11450480 — 2021 TESLA MODEL Y

The defroster system is not able to keep the windshield clear of ice buildup when driving even in light snow. This is because this is an electric vehicle, so there is no engine heat from underneath the hood to radiate towards the wipers. Between wiper cycles, the wipers rest below the area of the windshield that is heated by the defroster. During snowfall ice builds up on the wipers from their resting position between cycles and that ice then propagates to the rest of the windshield as the wipers move. This is an extremely dangerous situation. I heard Tesla is installing a heater beneath the resting area of the wipers on the 2022 model year of this vehicle. However, NHTSA should issue a recall and require this heating plate be retrofit onto earlier model years. The country of Canada is aware of this issue as well and currently investigating it.
