Yesterday, Transport Canada launched a "Problem Assessment Survey" for Tesla Model 3 and Model Y after receiving complaints from 16 Canadian owners about Tesla's heating, ventilation and air conditioning (HVAC) systems, which claimed that their Tesla Model 3 and Model Y HVAC systems, including heat pumps, were not functioning properly in extremely cold weather, while Transport Canada responded that they were concerned about potential problems with the vehicle's defogging and defrosting of the windshield , which can affect the visibility of the driver and lead to accidents. According to the agency, this time the investigation is not a recall.
Today, it was reported that the National Highway Traffic Safety Administration (NHTSA) also launched an investigation into these issues after Transportation Canada launched a "problem assessment survey".
The National Highway Traffic Safety Administration (NHTSA) said in a statement:
"NHTSA is aware of this issue and is continuing to gather information and will discuss this issue with Tesla and assess potential security issues."
Tesla may have been aware of the problem and has been working to fix the vulnerability by rolling out a wireless software update for affected vehicles, which it was supposed to launch earlier this week, but many owners said they didn't receive any additional improvements after the update, which could indicate a potential hardware issue with the glitch.
Tesla said in a statement to the Tesla Owners Club in Saskatchewan, Canada: "We take this cold weather climate issue very seriously — they are very worried about the safety of drivers and will definitely prioritize this issue."
