Just lost the heater (heat pump - M3) in my car for the 3rd time - I'm at a loss.

canadian_boi | 2025-12-23 03:06 | 114 views

2021 M3LR and they've replaced the heat pump/ac system in my car twice in just 80k kms now....last time was a $17k CAD bill (warrantied) but now they're *apparently* now extending warrant on their repeated faulty parts.... Super bummed as it's -20 C here in Canada and I don't have a functional vehicle. It's been every year I've had to get this POS worked on. Hate to rant, but please don't buy one of these if you're shopping for one...

Ooooh you’re not gonna wanna hear what folks here will say…

Turbulent-Pea-8826 2025-12-23 03:20

Don’t buy a car from a tech company, buy from a car company. At least if you want reliability.

canadian_boi 2025-12-23 03:36

Yeah it's a bummer for sure. Curious if anyone's had any positive recourse with the company following such events....

canadian_boi 2025-12-23 03:37

Give it to me straight doc!

c3p-bro 2025-12-23 03:40

You bought a car from the “least reliable” car company.

eclwires 2025-12-23 04:49

Tesla is a carbon credit trading company that happens to make EVs in order to obtain those credits. If you actually want a car; try buying one from a car company.

eclwires 2025-12-23 04:50

🤣 don’t say anything bad about Elmo. It voids the warranty.

Frequent-Sir-4253 2025-12-23 05:33

What did they say was causing so many to fail in a row?

m9u13gDhNrq1 2025-12-23 07:59

Toyota/Subaru EVs have a recall on their compressors as well. My car has been in the shop for a over a month so far waiting for parts. The dealer did hook me up with a loaner car they are billing to Subaru as part of the warranty work though. Apparently some people in Canada have waited for months with loaners since Canada doesn't have lemon laws.

Slytherin23 2025-12-23 09:19

Is that your experience too? What issues have you had?

rbetterkids 2025-12-23 09:23

My brother just lemoned his Model X plaid after constant repairs and mainly the rear motor creating vibration noises that the techs said wasn't under warranty. After he got a lemon lawyer involved, that was it. Tesla ended paying my brother back in full plus the lawyer's fees. My brother bought the model X plaid thinking if he paid premium, he'd get premium.

No-Astronaut-4194 2025-12-23 11:14

Not the person you asked but I’ll share… 2019 model X, random blackout of both screens - while driving at highway speeds, door handles (those little slide on thingies) that fell out, range that was wildly incorrect, oh and my favourite - front passenger side control arm failure that made car so dangerous to drive that Tesla had to load it up from my driveway on a flatbed. Just little things ya know.

grungegoth 2025-12-23 12:24

I didn't realize they put heat pumps in cars? Oh shit, electric cars don't have hot water/radiators.

BringBackUsenet 2025-12-23 14:30

Tesla isn't a tech company. It's a science fiction company.

BringBackUsenet 2025-12-23 14:31

$17k! I hope they are at least throwing in a jar of Vaseline.

BringBackUsenet 2025-12-23 14:32

So the battery drains faster too.

th3bigfatj 2025-12-23 14:41

This can't be true. I've never heard of a car's heater failing in my entire life. Even tesla can't fuck up a heater so badly it would fail multiple times in a few years despite the fact that they care about nothing but their stock price and Elon's comp packages.

th3bigfatj 2025-12-23 14:43

that's really an excellent point. Look back at some of the solar tile articles on electrek when elon was promising "cheaper and better" than a traditional roof. And installation rates of 1,000 roofs per week by the end of 2019. Now they've essentially stopped installations. It's just like their million mile battery, autonomy, robots, tunnels, etc. Elon never delivers. Tesla is so far behind on batteries and electric cars already. But, you know, they have a giant ipad in the middle of their incelmobiles. so it looks fancy.

[deleted] 2025-12-23 15:02

Before I spend even THREE digits on a car, let alone 4 or 5, I look at charts like this: [https://www.consumerreports.org/cars/which-brands-make-the-best-used-cars-a2811658468/](https://www.consumerreports.org/cars/which-brands-make-the-best-used-cars-a2811658468/) Do me a favor. Find Tesla. And that is not the first time they rank at the bottom- its year, after year, after year, for 10 years straigth. "I live in a cold, inhospitable place! I NEED A RELIABLE CAR... let's buy the first one I see!" ... Happy Christmas.

2_Scoop_Rice 2025-12-23 15:04

The dildo of consequences rarely arrives lubed.

BringBackUsenet 2025-12-23 15:57

The giant ipad is becoming more common even beyond Tessla. It's just more enshittification to save money. Sorry but in my car I want a traditional instrument cluster, and I don't want to fumble through a menu system when my attention needs to be on the road, so I want physical buttons and knobs to do basic things like adjust the heat, or flip to the next song.

BringBackUsenet 2025-12-23 15:59

No, it's a ponzi scheme that occasionally pumps out some widgets and trades credits for some extra pocket change to make the whole thing appear legitimate. They may as well rename the company Bre-X.

[deleted] 2025-12-23 16:32

Way to talk out of your ass

StinkPickle4000 2025-12-23 17:17

It’s like heat pumps were never designed to heat in really cold climes…

Dude008 2025-12-23 18:12

VERY common to have the heat pump not work when it got real cold in Canada when these cars first came out. Something would freeze up like a sensor or something and then game over. Is there a way to search from just 2021 heat pump?

ObviousCommonSense 2025-12-23 18:12

Teslas are notorious for having the worst build quality of pretty much any car you can buy in the US. Misaligned dashboards, panel gaps, paint issues, loosely fitted interior components... They're just very shoddily assembled and Tesla cuts every corner they can.

Material-Tax944 2025-12-23 19:27

It is interesting to see the many hate comments about the EVs. In my immediate surroundings. we are owning 5 Tesla over the past 6 years, all located in the frigid Canadian winter. Zero issues with the heating system… .

vovap_vovap 2025-12-23 20:18

Well, that is a thing - that electrical car. In a sense there is no source of natural heat there.

WishExtreme8104 2025-12-23 20:46

Laptop on wheels

Lopsided-Sell7595 2025-12-23 20:50

When you realize that the "product" is the stock, it all makes much more sense.

ionizing_chicanery 2025-12-23 21:34

ICE vehicles don't have heaters, they just circulate exhaust heat from the engine. So there's nothing to fail except the fans. That isn't the case for EVs because the motors don't produce enough waste heat, so they need actual heaters. Originally they mostly used resistive heating like a home space heater but they (including Tesla) switched to heat pumps which are more efficient. But even though heat pumps were already used for air conditioning using them for heating was apparently a complexity challenge at least for Tesla. Their early gen heat pumps are known to have reliability issues.

Icy-person666 2025-12-23 21:37

So just hop on your local hyper loop.

jcpham 2025-12-23 22:57

We have a M3 but I would only buy a cheap salvage title one from FB marketplace. It’s been reliable for a 2018 but I wouldn’t let a Tesla service center touch it. Either I fix it or no more Teslas in our household. We have a L2 charger at home, it’s never seen a Tesla dealer or been inspected- apparently it was a Covid total loss car from front end damage. But this is what I think of Tesla- worth buying as cheap as possible as a salvage title because the cars are completely shit anyway. No way I’m making payments and subscribing to Elon’s business model

Ordinary-Map-7306 2025-12-23 23:32

2021 was just a bad model year. They just replace it with the same bad parts from the parts warehouse.

earthman34 2025-12-24 01:15

Those credits are canceled, so now what?

eclwires 2025-12-24 01:15

Now what, indeed…

canadian_boi 2025-12-24 02:56

yeet

Xiaopeng8877788 2025-12-24 03:58

Vaporware company…

Sea_Share1841 2025-12-24 05:52

It's a stock selling company.

daveo18 2025-12-24 06:00

Hope you don’t mind me asking, and you may have had a legitimate need for multiple vehicles. But if not, how is owning five vehicles in six years meant to be saving the environment?

dtyamada 2025-12-24 15:11

Back in 2021 I remember seeing a bunch of stories about that, particularly in Alberta where it gets real cold. That was when I first became aware of Teslas poor quality.

dtyamada 2025-12-24 15:15

A quick google search would tell you this is a legitimate problem. But I guess when you drink the Kool-Aid you don't care about facts.

nlaak 2025-12-24 20:08

> Is that your experience too? It's the predominant experience, owners rarely listen, though.

nlaak 2025-12-24 20:10

Or call a RoboTaxi! There are millions of them now, right? I mean, didn't Elmo say there would be by years end? I mean, I get that OP is in Canada, but surely RoboTaxi has started to expand there, right? Right?

nlaak 2025-12-24 20:12

> I've never heard of a car's heater failing in my entire life. Tesla's are barely cars, and much of the design that goes into them is being pushed by someone wholly ignorant about manufacturing and uncaring about warranty or other problems. >Even tesla can't fuck up...so badly Oh ye of little faith.

Material-Tax944 2025-12-24 20:16

Immediate surroundings include friends and relatives.

Slytherin23 2025-12-24 20:29

I rarely hear about any issues.

uosiek 2025-12-24 21:17

Actually, HeatPump-equipped teslas have 3.5/7kW backup heat source. Vehicle can use motor coils as heaters and heat the coolant

Tesla ninnies need to stop call model 3s "M3". Keep that name out yo motha fuckin mouth.

canadian_boi 2025-12-27 15:19

Lol nah, I'm not typing that out every time dawg. Don't forget to use your blinker. BMW M3 is the legit m3 though.

randommmL 2026-01-21 17:54

Would you mind sharing the bill for 17k? I thought it would've been 5k (which is already bad) but 17k is terrible!
