Taycan ST RWD Battery Failure

[Andy@Longforgan]

This is my first post! Now into week 6 without my 8,500 mile July 2022 Taycan. Went to drive car at the end of January to find it completely dead (70% battery) and had to use the emergency key to open it. Porsche Assistance called out (The AA with no specialist knowledge except to use Google) but could not remedy and car recovered to local OPC. Battery has been removed from the car and a control unit replaced but fault persists and latest word is that a battery module needs to be replaced. The car needs to be taken to another OPC to have this work done and no timescale can be given for the work to be completed. Is it unusual for a repair to take this long and if not would it be reasonable to expect some compensation from Porsche by way of a discount on service or extended warranty?

Your 12V battery would have been the issue and not your HV battery (which was at 70%).

Not clear on what the underlying issue is from your post but if complete removal of the HV battery packs that is a huge job and will take several weeks. If the 12v and a battery module control unit then that's quite different.

They should give you a courtesy car but don't expect anything else - they're not a charity and are arrogant enough to not be that bothered.

Your warranty however (if original Porsche) is gold plated.

Thanks for your reply. I thought originally that the problem was low charge on the 12v battery but that does not appear to be the only issue. Porsche Perth have dropped the battery and replaced a control unit? as per advice they received from Germany but that did not resolve the problem. They now propose to move the car to Porsche Aberdeen to have some battery cells replaced but according to the app it is still sitting in Perth.
Have really enjoyed the car since buying it new in July 2022 but have lost faith since this episode and had values held up would probably have moved it on as I would not be able to stomach the repair cost outwith warranty. I plan to extend the warranty as soon as I can for peace of mind over the next few years.

Note your comments on Porsches' charitable credentials, I do have a Macan on loan but hopefully have the Taycan back fixed soon.

If it is one of the HV battery modules needing to be replaced the repair time will depend on the availability of a Porsche technician that has been trained for the work. Probably why they are moving the car to another dealer. That has been the hold up in the U.S., as only a few Porsche dealers have had one of the trained technicians. In some cases, they've had to fly a Porsche technician to the dealer.

HV battery fixes seem to be hit and miss, my HV battery was completely replaced with a new one in 12 days, where others have not had their cars for months.

Good idea to get an extended warranty, which will cover everything except the HV battery and its wiring. The HV battery is covered by a U.S. warranty of 8 years 100,000 miles but depends on the country of purchase. I purchased an Porsche extended warranty to align with the battery.

It's a terrific car, and once the bugs get worked out, you'll love it.

If the battery (12v) is disconnected then you app won't be communicating with the car and therefore the server between you and the car won't be getting updates.

Plenty of "new stock MY24" in Aberdeen - push for a swap / replacement and see how that goes.

I do love the car, just a bit disappointed at the time taken for the repair. Will definitely extend the warranty!
