One Edmonton owner got by on seat heaters at about -33 °C [1]. Tesla Motors Club owners have documented every stage of this problem, from the first cold-weather failures in 2020–2021 builds to compressor and supermanifold replacements. Here is what fixed their cars. ## What owners learned - Early winter failures were often fixed by replacing the pressure-temperature sensors, partly under a voluntary recall, plus software [1] · [2]. - A January 2022 firmware update ended deep-cold heat loss for some owners, but not all [2]. - Even a brand-new car can lose heat from a low refrigerant charge; one was recharged the same day [3]. - When the compressor fails, Tesla usually replaces the supermanifold (Octovalve assembly) with it: £2,864 + VAT itemised in the UK, $3,600 paid out of warranty in the US [4] · [5]. - Call Tesla support rather than only booking in the app; one owner got a no-heat visit moved up by about a week [3]. ## The first wave: cold air in Nordic winters The long-running “Model Y heat pump issues” thread started with reports of new cars in Finland, Sweden and Norway blowing only cold air [1]. A September 2020-build owner had both high- and low-side pressure-temperature sensors replaced, lost heat again a month later, got a software push that worked for a day, and finally had Tesla order a new heat pump and supermanifold, with a rental car in the meantime [1]. Another 2021 car had its heat pump replaced after it sprayed fluid while warming up, with no repeat afterwards [1]. After Tesla’s January 2022 software update, one Model Y that had lost heat for three hours of a 12-hour drive at -14 °C had no repeat, and a Texas owner was booked for pressure sensor replacement under a voluntary recall [2]. Members were not convinced software alone could solve every case [2]. ## No heat on a new car: check the refrigerant A brand-new 2023 Model Y Long Range blew cold air within days of delivery, with an alert that cabin climate controls needed service and heating or cooling was limited [3]. Service found the refrigerant low, leak-tested the system without finding a leak, suspected a factory underfill and returned the car the same day with working heat [3]. Another member said a technician reinstalled the firmware, which restored heat for a few days [3]. A reset or firmware reinstall is a reasonable first ask, but not always a lasting fix.

Service said the compressor had failed, which meant replacing the supermanifold too, and the owner paid $3,600. The A/C was worse afterwards and quit on the drive home, with no resolution posted [4]. A UK Model Y at 45,000 miles with an A/C fault code got the same pair under warranty at Tesla Solihull: supermanifold £1,043.75, compressor £658.71 and 7.04 hours of labour (£1,161.60), a total of £2,864.06 plus VAT [5]. A member questioned whether replacing both parts on a mostly working system was guesswork [5]. Report any climate warning while the car is still under warranty.

Independent Tesla specialists do work on the supermanifold, as the video below from a repair and used-parts shop shows, but refrigerant work needs proper recovery equipment and is not a driveway job.
