My factory heater is still working!

Is your original heater still working?

I had been reluctant to place a vote yet but I have had the car 2 months now and so far so good.

Just back from the dealer in Germany (for a small silicone rubber issue on the mirrors), as well as driver side charging port doesnt unlock the cable.
I also complained about foggy inside, as the car seems to have trouble clearing fog (especially on the panoramic glass roof even when a/c is on.....perhaps the prelude to an issue to happen?? (I drive a 2023 CT4s).
Back on topic...i asked them about the Taycan heater issue...and apparently there are 5,500 cars stopped from delivery to customers as heater not installed (or a part of the heater not sure). In Germany alone 320 cars delayed. Delays up to 13 weeks apparently.
Perhaps someone experienced this delay? Or can verify otherwise?
Cheers from The Netherlands.

Oops, my 2020 Taycan just had the heater fail for the first time. I updated my vote.
Last night my Taycan MY20 also had a heater fail and it was scary to see the battery temperature dropping to -11 and probably today will drop to -17 . Even with the steering heater working my hands were frozen.
In Manitoba (Canada) it is dangerous to have this type of issues in the middle of winter and Porsche should recall the Taycans sold in Canada and other countries with harsh winters

Got my 2022 with 5500 miles on it back from the dealer today after three weeks in the shop with no heater.
Once the heater came in I had the car back the next day. My only concern is the service manager said Germany send the US a large batch of replacement heaters last week but he was not aware of any changes or upgrades! Thats concerning......will they fail again?

Had a weird 24hrs late December where the heaters weren’t blowing hot air then it seemed to fix its self. No issues since.
I've experienced this a couple of times, and I realized my A/C was in 'Eco' mode. The drop in temperature of the blown air is instant and significant, and I guess it makes sense since the heater is electric.

Ah yes that makes sense! I think mine may have been in Eco too.

I wonder what is the minimum temperature under which the HV battery starts failing. The battery has the heater keeping it from freezing temps for a reason.

Yes to daily timer with set departure, but not Preheat.

I do that adhoc as needed.
I've been messing with the charging settings. I've noticed that when it's on a timer, there is some amount of "pre heat" for the battery. It was 28*f outside and my battery was at 55*f. Departure setting set to 50%,7am, recurring daily. The battery shouldn't have been charged as it was already at 50%. The battery is cold if I leave a general profile on. ?? Hv heater kicking on to warm the battery?

If you "wake" the car up, or if it's doing anything overnight (updates, balancing, brake blending etc.), the battery will drop and the timer kicks back in. I've also noticed that even with charging on hold (but plugged in), the battery is warmer than otherwise.

I am concerned that it's causing hv to be kicked on and excessive usage will translate into higher failures. Though, if it can't handle this type of usage pattern, that's also a red flag.

My theory re HV failures (based on what I read here) are rapid heating-freezing cycles in high humidity environments - either direct, or perhaps as a stress/fatigue failure from those cycles. I don't recall of a failure reported in a garage/enclosed space (presumably that eases the temp gradient that the unit is experiencing).

The scenario I'm dreading is a variation - hard drive to some cold spot (like, say, to the mountains), then park for hours in low temps. I'm genuinely relieved every time that happens and the heater appears to still be working.

HV system will energise if the 12v battery requests charge when the car is otherwise powered off. From what I’ve read if the car is otherwise well and systems are dormant that should be approx once a week to maintain the required SoC in the 12v batt. I don’t think otherwise the HV system is energised at rest.

Just took my Taycan to our local Porsche dealer to diagnose my broken heater. Sure enough, it needs replacing. They ordered the part and it will hopefully be here in a couple of weeks. My service advisor did indicate that he's seen more than a few in the last couple of months. Perhaps California’s somewhat mild winter and temperate weather disguised the problem for longer than I knew.

If the heater does fail while you're on a trip, have a plan for how to get home without being able to fast charge. Yesterday at a 150 kW EA site, in 30 F weather, the battery only reached 42 F after 30 minutes, with peak charging power of 11 kW. Prior to my heater failure, I would typically exceed 100 kW in cold weather at this site.

Doesn't the battery heat up while DC charging (via the charging inefficiencies rather than the heater)?
