HEATER FAILURE A REAL CONCERN

[Tooney]

Until there is a solution to the fault causing the failure it is just a question of replacing failed parts with the same type until the redesign is in production and proven. Then the reliable ones will obviously go into new builds first then eventually be available for a recall IMO.

Interesting management decision:
Proven, reliable heaters eventually become available, but are in short supply. Supply those improved heaters to existing owners whose Taycans have no heat, use them to recall existing inferior heaters that should be replaced to prevent future failures, or use them for new builds?

If the 12V battery shortage is anything to go by the first ones will go to production so the number of people pissed off by delivery delays are minimised.
The next logical step would be to start using the new design to replace failures. This assuming once the new design is available they won’t order any more old ones and the delay for existing customers with a car at the dealer awaiting fixing will be longer until the updated units are available for repairs.

The 12V battery issue showed that having a smaller number of very pissed off customers was better for Porsche than annoying more customers a bit less.

All very well if you aren’t one of the ones very annoyed, as I was waiting from April production start to December delivery for my car.

Maybe it will be a software fix to existing unit similar to the eventual fix for 22kw charger issue.

We have 3 company owned taycans,all just under 2 years old,all 3 now have heater failure,all in the last month,earliest date porsche reading have given us for a repair is the 20th april,and was told to wait for a frosty morning,ring provided breakdown cover,and they will tow away and provide a car to use,really,not what i expect from porsche,damned dangerous to have to drive a car in frosty conditions unable to clear the windscreen,somebody is going to end up being seriously hurt,and porsche will be hit with one allmighty lawsuit.There needs to be a recall ,and a dont drive for safety reasons if you have the heater failure letter sent to all owners.How did they let this slip through the development stages,and as for the door rattles 'They nearlly all do that sir' All 3 have them as well!!!

Seems like something that is survey worthy on this forum. How many owners with at least 2 years or 15-20k miles have experienced heater failure.

Our Taycan 4S, 2yr old, 19,000 miles, heater failed Feb. 1, 2023. Dealer fixed it on March 1, 2023. Glad the seat heater and steering wheel heater both worked.... it was a cold month. Dealer reported 3 other Taycan's had heater failures. Seems like a serious design or quality control issue for Porsche.... this should not be happening.

Mid Dec, 2022 - Heater failed (4,000 miles)
Jan 16, 2022 - First appointment with a loaner
Jan 20, 2022 - Yes, your heater is broken. Part is backordered.
Feb 27, 2023 - First appointment with loaner and part in stock.
March 2, 2023 - New part is either broken or there are more problems. Ordering multiple parts from Germany. Of course everything is backordered. "Keep the loaner".

Not what I expect from Porsche. And...still no recall for an obvious major flaw.

today my 2nd heater failed.
let's see if they can fix it in one week.

It is not a safety issue for a reason. Thing is that cold air is used to defog the windshield, not hot air. At least in mine it worked with the heater dead. Waiting for mine to be replaced.

Defog uses A/C to dry the air and heater to heat it back up. Without a heater, you will freeze the front windshield with AC only. I've experiences this on another EV where the software screwed up and would not turn the heater on when defrosting.

Well I will see for myself next week. I'm done with the loaner Macan and told my dealer to prep the Taycan. I'll drive it with the dead heater and when it comes I'll hand it back in.

What model year is your Taycan?
When did the first heater fail?

MY21, built in 12/20, first heater failed in 1/2022.
Hardware revision seems to be purely coincidently, as the first H11 died last fall.
Will try to find some DTC with VCDS later. they are well hidden afaik

Interesting (apologies for going off topic), didn’t realise that VCDS works on a Taycan?

I don't see any logic in doing the recall until they have enough resource, both parts and manpower, to do it.
It is already a long delay for a lot of customers to get a failed one replaced, imagine how much longer it would be if they were proceeding to replace all the non-failed ones at the same time.

Annoying but obviously what they have to do IMHO.

Agreed. I think at this point we have to assume all cars from MY20 through MY23 will likely have a heater failure. My neighbour's MY22 4S CT failed last week.

Production must surely stop for now.

You would of thought that they would stop production as not to add to the increase with failures, BUT as with most companies, the accountants/investors call the shots nowadays so would not be surprised if they keep producing as they will want revenue to keep coming in from new sales.

They were - my new GTS ST which I picked up last week is testiment to that as it was produced in Jan'23 and delivered in Feb with half a heater fault.

Now I think they've stopped the line.
