FYI: Main Battery Replacement Needed!!!

[whitex]

Just had the same problem with my 2020 Turbo (29k miles). Luckily my dealer had a Taycan 4S loaner. Car has been with them for 5 weeks and they just got back to me and said that they will be repairing the cells in the battery. I'm not sure how many cells need to be replaced out of the 396 in there. I wonder if this will be a stopgap on the way to a full battery replacement.

Dealer will repair the cells, or send your battery out somewhere to get fixed?

4 cells need to be replaced. They will bring in their regional battery repair engineer to do the fix

Interesting. It must be cheaper to fly technicians around than ship batteries to a regional repair center.

Got the car back on 12.12 after 2.5 months at the dealer. Three days later got the dreaded 'Electrical System Error' message again. It took 3 tries to get the car started. I'll have to take it back to the dealer again. Does anyone have any recommendations on what I should ask for? I'm thinking I should insist on a full battery replacement.

Yes you should request a new battery. Mine has been in the shop for the past four months and they decided to just replace some bad cells. Very nervous this will happen to me now. Was really hoping for a new battery the first time. Vehicle has already been in the shop for three times longer then it’s been in my garage

More time in the shop than in your garage, that must be very frustrating. I wonder if these problems are just with the early versions of the car. I bought mine used but it was one of the earliest 2020 models.

It’s not seen plenty of 21 and 22’s going through the same thing. One thing that does concern me on the 20’s is the mixing of the different battery cells together.

Man just when I’d fully convinced myself to go all in on a Taycan, I stumble onto this thread

I’m going through a HV battery failure on my Model S right now….but this is after 10yrs. And even though it’s not surprising, it still sucks. So this talk of it happening so soon (and often?) on the Taycan is concerning. Yes there’s warranty and loaners etc…but that’s not what you want when you spend that much $$$, you want the actual vehicle.

Theres no way to get an idea of how prevalent this issue is, is there?

I really don’t want to go back to Tesla

I haven't figured out a way to get a sense of the prevalence of this. There are a few threads on the forums here and several people on each forum, but that doesn't really tell you prevalence. I've done a few web searches to try to get something more quantitative but haven't been successful

Reviewing problems vehicle owners have experienced before buying is a very good idea.
Individual owner opinions vary, of course.
Recurring polls and discussions on this forum give me the impression that most Taycan owners who post here regularly do not regret owning their Taycans, even after experiencing problems.

To share my experience/status, for what it is worth: my 2020 4S, which I acquired new in November 2020 and have put about 17K miles on has been at the dealer since mid-October after a yellow "Electrical system error, service necessary" message popped up. Most of the time since then the updates I got were limited to "we're working with Germany, doing the diagnostics they request and waiting for answers." That was followed a couple weeks ago by being told Germany is trying to decide whether I need a new battery or cell replacement, and that the decision apparently would be based on what cells were faulty as there are different types. Finally, I was told last week it would be cell replacement and the holdup was going to be getting the regional battery technician in. I was told he is currently in Atlanta and it was unclear when he would make it to the Boston area, suggesting that there is only one guy and his territory is at least the entire east coast of the US.

I've come to terms after 3 years of ownership that I just have to roll with the issues (e.g., no heat last winter, resulting in about a month out of service) and not get frustrated. I enjoy the car very much when it is not in the shop, have had no issue getting loaners, and understood when deciding to go first generation electric that it probably wasn't going to be all smooth sailing. There is an 8 year battery warranty and if replacing cells rather than the entire battery proves to be penny wise/pound foolish, I'll take it back when there is another issue. I have no interest in doing a deep dive on battery technology to figure out if they are being entirely straight with me.

Other 3 year ownership notes: my ownership anniversary (which passed with the car in the shop) meant the end of free EA charging and Porsche Connect services. The free charging was a nice bonus, though not used all that often. I mostly used it on Boston-Philly drives, but as the EA locations have become increasingly crowded and unreliable over the last three years, we now prefer to avoid that and take our plug-in hybrid for longer trips. I think hybrids are going to be the sweet spot until big improvements are made in the public charging network, especially if the battery range can get to about 50 miles, which for most will allow home electric charging for pretty much all daily driving and gas for the occasional longer trips. That Porshe feels the need to squeeze over $300/year for a Connect contract on a $150K vehicle does piss me off and I refuse out of principle. The connection didn't work at all for the better part of the first year of ownership before some software updates and the only feature I will miss is the winter pre-heating.

I would agree. It really is a dream car that I love to drive. If they offered me a refund on this car, I would take it. But, I think I would probably rol the dice on another (newer) Taycan. It's such an amazing car to drive.

Most of the people on this forum have not had this type of issue. You can go read the forums of every car in existence and get scared off from buying one. Nobody can guarantee that a battery failure won't happen to you but overall most people on this forum are thrilled with their Taycan and would purchase another one. There is a poll about owner satisfaction on here and the overwhelming majority love their Taycan. Good luck with your decision.

 

[LongLive959]

Decision is basically made. Just need to wait until the new year for tax/finance reasons…which is just around the corner. Eying the cpo listings every day

and yes, I know that forums are where ppl will share these types of stories, so it is a skewed view.

anyone here experience multiple battery failures?

My 2 Yr Old Taycan Turbo S died in the driveway (after simply backing it out of the garage) with the dreaded "Electrical System Error" (Red).

The car would not move (although the Console, Nav, etc appeared fully functional). Seems other folks have had the car towed, but I don't look kindly to some guy dragging my car up on a flatbed. I did find a report that sometimes the issue will "go away" so I waited, and waited, and finally got the car back into the garage. Porsche wanted me to simply have the car towed to them, but I said I would rather risk it and drive it (if possible) - as it could always get towed if that didn't work out. I successfully drove the car to them where they have now had it for a little over a week.

They pulled the diagnostic codes, and in conference with technicians in Germany, It has just been determined that it needs a whole new main battery pack (which must be shipped in from Germany). Based on folks who have reported similar issues, I'm expecting the car to be in the shop for 30 days or more. :-( The dealership gave me a Cayenne Loaner so they are covering the outage to the best of their ability...

I'm on my 5th EV and never had ***ANY*** battery issues with my Tesla (MX), BMW's (i8, IXM60), or Chevy (Volt). We all know about the issues with the 12V battery (that required replacement), but it also appears the main battery (and/or onboard charger) may have its own problems: https://www.teslarati.com/porsche-whistleblower-taycan-battery-charger-fires-coverup/

How many miles did you have on it?
