I remember seeing your posts when you received your car. Not that long ago. Had mine year and four months. I just left it a few hours and same issue. I moved my key FAR away. Will check later.



Noticed on MYPORSCHE app, the car in the bottom left is colored red. So guessing the app got notified by the car.

Gonna do my best to not sound salty here. The response from Porsche so far has fallen horribly short of a reasonable standard. Here goes....

This is a really concerning aspect of the Taycan - same warning on the dash, inconsistencies in how its tracked in the ECU, and it has a spectrum of resolutions. They range from what is effectively a control/alt/delete from the driver to an uh-oh, your entire main battery is toast. These warnings about as helpful as idiot lights from 30 years ago. How can this be?

If I had this warning and was able to reset my concern would be what happens the next time? DId I mention that this same issue happened to me about 5 months ago and then it magically went away and Porsche couldn't see anything logged with a scan?

I was doing some research and I see that some others also had the fault disappear. I was hoping that would be my case.

I agree, though, how do you know it will not re-occur and at an inopportune time.

I did get the yellow electric fault one time right after getting the car and well before the big uPdate. Never happened again and it just needed a 5 min lock of the car and walk away.

You know what else is an issue, the 12V is being drained with me locking and leaving it to go to sleep and come back to try again.

Hi Archimedes, quoted range for performance battery by Porsche from the website is

My question is has anyone achieved this or even close to this as in the 2 weeks i had the car it never indicated anything more than 210 miles in range mode. Taking account of cold weather (say -20%) it should say 254 miles.... I have an electric yacht and the slower you go the further you go (massive difference). I was wondering if I have a defective battery and thats why the question. I'm looking forward to getting the car back from the garage and driving really slow zzz to see how far I can get. I realise its completely un Porsche like and it should be driven as though you have just stolen it

If you load this page:-

https://www.porsche.com/uk/models/taycan/taycan-models/

and scroll down to the range calculator, you can see the influence of things like which model, wheel size, type of road A/C setting and ambient temperature using menu selections and sliders.
It is interesting to see the actual influence of, say city v motorway driving, ambient temperature and the A/C settings

My CT 4S predicts 225 miles on the dash at the moment for a full charge, it was less when it was colder. This range calculator predicts 217 fwiw
I haven't owned it long enough to have a warm weather estimate but with my personal use range isn't going to be of any importance apart from about 5 times a year so it hasn't been a worry.

I must say my original thoughts on owning an EV was I wanted to get to my daughter's house without needing to stop, which is 225 miles and my pre-ordering research on the Taycan indicated thet would be only possible in summer.
Having done it in winter with planned charging/coffee stops it turned out my wife preferred that to non stop anyway...

Hi, I started this thread because I broke down in the first 2 weeks of ownership. I was worried that the failure of the HV charger had affected my battery life as I never got more than 210 miles from it and the Porsche website says over 320 miles ….. I tested it this weekend when it came back from repairs and got 220 miles in Range mode with no AC doing 60 miles per hour ( average speed cameras) for 150 miles plus returning 150 miles, so 300 miles test in one day. Outside temperature was 8 degrees C, quite warm for winter in Scotland. Car says it was 2.6kw/mile on the way and 2.4kw/mile on way back ( I was tired of being overtaken so much!!) so even if there is 20% reduction for cold weather (but 8 degrees is not that cold) the real figures are 2 thirds of what the website sells. Yes I know they use some ridiculous testing regime and no one really expects 320miles but it’s clearly mis-selling. BUT as your partner says, no-one can go 3 hours driving without a break anyway, so stop moaning and have a coffee for 30-60 minutes if you can find a supercharger half way….. I was lucky, out of 4 IONITY chargers I got the one that worked! So I’m home now, and the verdict is….. this is the most beautiful car ever, people stop and stare or noisily overtake out of jealousy (range mode) but the beauty is skin deep. It is as flawed as every other electric car out there, but wonderful to drive and look at!

I am just surprised you are surprised.

I investigated my real use cases extensively before ordering a Taycan and didn't expect more than 225 miles of usable range.
I had never seen the 320 miles you mention anywhere I looked.

Anyway I hardly ever do long journeys, or drive on motorways. I wanted an electric car for the quietness and instant throttle response it gives, not for long distance driving for which I had thought everyone knew a different approach was needed than an IC engined car, and I was pleasantly surprised how well that worked out on the 2 days I have done a long journey since I bought mine.

It is absolutely perfect for me except being a bit big.

If you are disappointed I can only suggest you didn't look into your purchase very thoroughly before placing your order, I'm afraid.

the 320 miles os on the Porsche website, you clearly missed that in your thorough investigation.

One mention of a possible absolute maximum in a vast pool of information is not an important data point for an engineer when there is a possibility of investigating the whole range of different driving conditions, and I for one have never seen it.

I just used the Porsche range calculator on their website to look into my likely use cases.

For my choice of Taycan CT 4S with 21" Cross Turismo wheels on the road profile going to my daughter's house it calculated 211 miles in 20C ambient, 199 miles at 0C ambient (which is what it was when I did the trip). Going to 20" winter wheels added about 12 miles.

I was not expecting more than that so stopped for a drink a couple of times at a fast charger on the way and had zero range anxiety or any surprises.

I can get the Porsche prediction to 300 miles only by zero town or motorway, A/C off and 30C ambient. Never to 320 on a CT 4S.

So as far as I am concerned the Porsche web site gave me an excellent tool to investigate the influence of driving conditions and settings for the car I chose before I placed an order.

It wasn't hard.

Or maybe you are just trilling?

The Porsche mileage estimator, at least on the .com version for NA doesn't allow you to zero out city driving - you can lower it to 5% (when I played with it).

FWIW the 'real' range is best looked at to be around 200 miles. And if you are going farther than that in a single day you are likely on a motorway/freeway so your mileage will stretch...I think 300 is pretty unrealistic though. Not many cars actually accomplishing that without the driver hypermiling etc. The Lucid the EQS appear to do it (but havent heard real world yet).

Really, these cars carry about the same distance capabilities as a v8 turbo sports car with a 20 US gallon tank. Plan your outings accordingly.

this happened again this morning!

this happened again this morning!

Mine happened Saturday. My 12v eventually died with me trying to do the two finger salute. Leaving it locked with the key far away. Pop the frunk and keep it open incase you have to jump the 12V to get the car in neutral.

Dealer cannot figure out the issue. They put a PRMS to Germany to try and get them to diagnose what is up.
