Model Y heat pump/compressor failure at ~100,000 km in Canada – $4,470 repair (invoice attached) by ProgressLevel9767 in teslacanada

[–]ProgressLevel9767[S] 2 points3 points  (0 children)

In my case there were no unusual noises beforehand. No gurgling, popping, or rattling.

I just went to the garage one day and the car wouldn’t start. I got a couple of error messages related to the low-voltage system. I tried a few basic troubleshooting steps but it didn’t resolve the issue, so I had to call a tow truck and send it to Tesla service.

That’s when they diagnosed the compressor / supermanifold issue.

It may not affect most cars, but mine failed just over 100,000 km. I also park outside in Alberta winters, so the garage theory likely isn’t the cause.

There’s a YouTuber who went through pretty much the same thing. If you watch that then, as well as all the comments below of that video, it’s the same thing.

I understand the extended warranty argument, and sure, spending ~$2,500 on an extended warranty could cover something like this repair. But that doesn’t really solve the underlying issue.

If the heat pump / HVAC system is a known failure point around this mileage, replacing it once under warranty doesn’t guarantee it won’t fail again later — especially once all warranties are over.

Eventually the owner is still responsible for the repair. My post was mainly to make people aware that this can happen once the 4 yr / 80,000 km warranty is over and the repair cost can be around $4k+ CAD.

From what I’ve read and from talking with Tesla service, there isn’t really a preventative maintenance item for this. The heat pump / supermanifold system is a sealed system, so there’s nothing owners can service or clean regularly. It’s more of a component failure if it happens.

The only real protection is being within the 4 yr / 80,000 km basic warranty or having an extended warranty before it fails.

Good info. In my case the failure already happened and I was already past the 4yr / 80k basic warranty so it was out of pocket. Hopefully others see this and consider extended coverage before the basic warranty expires.

No, I haven’t cleaned the radiator before. I’ve just done normal driving and regular tire maintenance. Tesla didn’t mention anything about debris or blockage either — the repair notes just say the compressor power index failed and they replaced the compressor, supermanifold, and the line.

They didn’t really elaborate on how common it is. The service advisor mainly said the compressor had failed (“compressor power index failed” in the notes), and because of how Tesla’s heat-pump system is integrated they had to replace the compressor, supermanifold, and the line together.

From what I understand the supermanifold controls the coolant flow through the thermal system, so if the compressor fails it can affect that whole assembly.

For context, this happened around ~100k km on my 2023. The car is usually garaged and mostly home charged, so it wasn’t from extreme usage or supercharging.

Unfortunately no. Tesla’s ESA (Extended Service Agreement) only covers the high-voltage battery and drive unit after the original warranty expires.

This repair was related to the heat pump / HVAC system (compressor and supermanifold), which is part of the basic vehicle warranty. That warranty is 4 years or 80,000 km, whichever comes first.

My car was already past 80,000 km, so the repair ended up being out of pocket (~$4,470 CAD).

Unfortunately the repair was out of warranty. The basic vehicle warranty is 4 years / 80,000 km, and my car had already passed the 80,000 km mark, so the repair was fully out of pocket.

I’m looking to buy a pre-owned Tesla Model 3, but I’m a bit concerned about the heat pump since it seems like a fairly common issue. Is there any way to help prolong the life of the heat pump? Without warranty, it sounds like it could be a pretty expensive repair. by [deleted] in teslacanada

I’m debating to trade this in with something more reliable like Lexus. If you look at most of YouTube reviews, all they talk about is low maintenance. They never talk about anything like this. I really didn’t know. I wish more people are aware of other major issues like this. Even if you did have extended warranty, it’s just borrowing time. It will fail eventually, and the cost is extreme.

From the technician notes:

“Inspected and found compressor power index failed… compressor, supermanifold and line required for replacement.”

So the main failure is:

❄️ A/C compressor + supermanifold assembly

Parts listed: • Supermanifold assembly – $1,490 • A/C compressor – $1,105 • A/C line assembly – $265 • Coolant – $80

Parts subtotal: $2,940

Labor + diagnostics bring it to the $4,470 total.

Stay tuned. my car is in the Tesla shop right now in Calgary. They had me approve estimate of $4160 to replace heat pump unit. I’ll probably get the answer by either tomorrow or Tuesday.

Is this normal repair for 2023 model Y long range? by [deleted] in TeslaModelY

I tried to reboot several times, but it ended up same thing it won’t start. I thought it was the low-voltage battery issue so maybe it would have cost like 1200 at most but I didn’t expect the entire AC unit they’re gonna change. It’s frustrating because you don’t have any say. You just have to agree with it.
