Heater broken. My turn.

[W1NGE]

They're all made in Ireland as it happens.

My MY21 4S heater failed 2 years after ownership and on pick-up of my GTS ST (which had a stop sale due to a PDI detected heater failure (!!), since then it has had the heater replaced as part of other recall work but not due to a failure.

HV heaters are obviously prone to failure which in this day and age is hard to fathom.

I guess europe doesn't get that kind of treatment ?

Well I am on my 4th heater in my car. I had one replaced in 2023 to be the new improved one manufactured after a certain date in early 23. But that one was replaced again at the service in 2024 for an even newer one! So I hope we will see the end of this soon.

By the way the BMW i4 is equipped with two heaters, each one capable of 9 kW. Wonder if they have failure rates the same as Porsche. Do they install two for safters reasons so you never without some heat??

Not something I aspire to

In switzerland, they have it in invetory at most dealers that work with taycans. ? So clearly they expect these to fail often. I wonder if they redesgined it at any point, but seeing as how 2024 still fails, likely not.

Curiosuly enough, knock on wood, my 2020 never had a heater failure. But then again, I don't heat up my car to 29 degrees celsius, i stop at 23 or 24 max.

I never went above 22 degrees and first freezing in December fritzed my heater. Maybe your are just lucky. And afterall a large % of owners don’t see any problems. Maybe you will never have a problem. But a too high % of other unlucky knes does have the issues.

Other issue. But just heard someone with a 22 kw charger defect collected at home and repaired at Porsche Centre East Flanders within 24 hours. Good service !

Yipes, sorry to hear about that poor track record!
Especially the failure of the 2023 replacement.

As for the i4, the equivalent forum has its share of the equivalent Red Circle of Death failures that come seemingly out of nowhere.
And some heater coolant leak failures.

But nothing like the Taycan heater tales of woe.
(Our i4 has almost 40k miles and the only casualty so far has been a parking sensor that got taken out by an almost imperceptible rock chip.)

Looks like it's my turn, with a MY2024. Right after I picked it up from the dealer for other issues too, clearly something there triggered it.

Have to wait 2 weeks to schedule with dealer, better off calling 1800Porsche?

Is this a J 1.1 or a J 1.2 facelift ? Good luck on the repair. Can be quick depending on the stock.

Thanks! I hope it’s quick… J1.1, MY24

All the PTC 10kW heaters in the USA, up to 2024 at least, are marked "Made in Germany." Some say the failures were due to a faulty solder joint, but that doesn't sound right, given the longevity of the problem across different versions of the PTC. The PTC maker, Webasto, has been in business forever, but Taycan is the first EV with an 800V system. This might be their first PTC that operates well above 400V. That might have been the issue.

Apologies I was thinking 22kW AC onboard chargers which are made in Ireland for Porsche.

Webasto makes the HV heaters as.you correctly point outnand most likely in Germany.

Even if the reason is the 800V system I don’t think it’s an excuse. For Webasto and for Porsche. At this price range they should have tested it thoroughly. Maybe even Porsche more than Webasto. Hundreds of cars needing a repair and going in for sometimes weeks not being able to drive in cold weather is just not what to expect. Wonder who made the decision to use this HV heater. Probably doesn’t work at Porsche anymore.

Perhaps heater failure is not considered safety equipment failure where you live. In the US, government regulations often force recalls for potential safety failures, even in cars out of warranty.

I always feel the Taycan was rushed to market.
Far too many issues that should have come to light under testing.

I assume they produced it along their usual timescales, without thinking about the intricacies of it being the first of a kind, with a whole new spectrum of teething problems.

IMO, the traditional Porsche bit they got right (driving dynamics. Chassis etc).
It's mostly the new stuff that brought the problems. And not having technicians trained or ready to deal with it.

Yea, this new fangled, revolutionary brake lines concept was just too much for Porsche engineers. Evidently door handles are also just too modern (my Taycan on my 3rd door handles, still not working 100%, service will happily just keep on swapping them per Porsche instructions, but what are the chances I got 3 bad sets and it always fails on the same one? I just told them to stop replacing as it seems insane to just keep on doing it, I might try to debug it myself someday, until then I use the back door handle when the driver's door fails).

Not saying the EV stuff doesn't fail, but it seems they have failures and recalls across the board, not just "new" EV stuff.
