Canada’s auto safety regulator has opened an investigation into the heating system of Tesla Model 3 and Model Y vehicles.
The probe follows 16 consumer complaints about the vehicles’ performance during cold weather.
Transport Canada is concerned that a malfunctioning heating and air-conditioning system “may affect windshield defogging/defrosting and therefore driver visibility.”
The regulator said it has informed Tesla of the investigation.
A Tesla news provider, Drive Tesla Canada, reports that a number of Tesla owners complained that the heat pumps are failing in extreme cold temperatures.
The report said the heating problems happened even after Tesla early last year replaced faulty sensors in heat pumps in some 2020-2021 Model 3 and Model Y vehicles to address the issue.
