Taycan Problems are overwhelming an otherwise great car

[charliemathilde]

Porsche is overall excellent as so is the Taycan - but they have always been a stubborn company, and never telegraph their plans to "fix" known issues - they quietly release the new product with 'fixes' and they never seem to call attention to the fact that it should have never been broken in the first place…

the key indicator for me will be the Macan roll out - any "lessons learned" should be present in that platform and will be a window into any future improvements in the Taycan - but for now we have a well established set of a short comings for the Taycan - I do not expect them to be "fixed" anytime soon - but some may be mitigated with a Taycan refresh - with any serious attempts to improve the Taycan being pushed to a full refresh post any facelifted Taycan - I would estimate 2028/2030 for a full generational improvement in Taycan…

but that's just my $0.02 - but it is frustrating to not see any demonstrated interested in the issues we know all know and take for granted.

well one of the things they claim they learned is that they were much too conservative over provisioning the battery with the reserve capacity, and the reserve would be much smaller in the Macan.

ironic for this thread.

in any event, if OP can’t get them to do anything, I’d suggest enjoying a lot of miles and high energy charge sessions until the battery drops 4% more than then make a warranty claim to have them replace it. Check out the details for the 8 year warranty

Vim,
Fellow Cincinnatian here - I had some issues early on with the car just blanking out and never really got accustomed to building long trips around the meager supercharging network here in the midwest so as prices plummeted on my 2020 Turbo, I swapped into a 718 Boxster GTS 4.0. I miss the pull of the Taycan for sure, but appreciate more the nimble handling of the 718. I have to get used to going to gas stations again, so there are plusses and minuses. I was not the right guy to pioneer this technology in the end.

Email Kjell Gruner, the President of Porsche North America, with your story and concerns. That's worked for me. His email address is:

[email protected]

EDIT:

In light of Dave’s news that Kjell has migrated to Rivian, reach out to Simon Kuhnimhof at Porsche NA Customer Relations. Knell would have most likely tossed the ball to him anyway.

[email protected]

Thank you very much for the contact. Here is the text of the email I have sent. Fingers crossed.

Dear Simon,

I'm writing to you because I've been working with my really excellent dealership on trying to figure out what happened to my Taycan battery, and they just don't have any answers.

I purchased the first Turbo S in Ohio in September of 2020, and it's the best car I've ever had. I'm quite familiar with Porsches, since I have been racing Porsches for 15 years. This is my first electric vehicle.

To summarize the issue, I brought the car into the dealership due to a faulty charge port cover, and they repaired and returned the car on August 13. I've been charging my car using the Porsche charger for three years and 30,000 miles, always at 85%, and I have never had a reading of less than 200+ miles at any time in over 500 charge cycles. My readings have gone down slightly in the very cold weather, but again, never less than 200 miles. Before I brought the car into the dealership, I took a picture of the dashboard showing the error message, as well as 236mi estimated range at 85% charge. When I got the car back from the dealer, I did what I have been doing for three years and plugged the car into my charger. The next morning, I got a reading of 170mi range at 85% charge.

I love this car, and as I've said, Porsche of the Village has really been an outstanding dealership for me over the last 10+ years. They have run a number of tests on the battery, and can't find any problems. Now, they are getting 167mi at 85% charge, and they are saying there is nothing further that they can do.

As I said, I absolutely love the car, and the dealership is outstanding, but it appears that we are at a dead-end. Can you help me figure this out?

Thank you very much,

Mike Hooven

Re: energy consumption, use the trip display in the instrument cluster as you drive. My Taycan 4S would typically use 36-40 kWh/100 mi. If your consumption is much higher, that may be the cause of your reduced estimated range.

For what it's worth, 20 years ago I picked up a custom order 911C4, managed to wear a tire all the way to blowout, with zero track use, in about 6 months. I had the alignment checked, not problem, turns out it was my driving style and Porsche appetite for tires. Both rears were pretty much down to wires, one of them blew on me at ~90mph on a highway - not as horrible of an experience as you'd think, got towed off the highway, put on the donut spare, got all 4 new tires (fronts were less word than backs, but still very much ready for a swap). Now I check Porsche tires more often than every 6 months, an interval I use for all other family cars.

My miles/KWH on the three days prior to the dealer

You make an excellent point. My consumption in terms of mi/KWH has not changed. It was 3.2, 3.2 before taking it into the dealer the first time. I then saw the dramatic decrease in range, and on the 23 mile drive to the dealer my mi/KWH was 3.4. This would indicate to me that the battery capacity has decreased significantly. If you calculate what they are currently showing at 100% capacity of 197 miles, this would indicate a battery capacity of only 58KWH at a consumption of 3.4mi/KWH. And yes, my range indicator went from 167 to 145miles after the 23 mile drive to the the dealer, so the indicator is good. If the range indicator was as bad as some people say, people would be getting stranded on the road because they thought they had enough range to get to the next station. I think it has to be reasonably accurate for this reason.

On the tire wear, my guess is that your tires showed a higher wear on the inner tread. This is what makes this problem so confounding. There was NO increased wear on the inner tread, all 4 tread markers showed 4-5mm of useable tread across the width of the tire.

Here is an update to the post I sent this morning:

Dear Simon,

In addition, the car's battery capacity has gone from 96% at 10 am on Friday to 83% at 7:00 am on Monday with no work done and the car parked at the dealer the entire time.

Realize you ay have a genuine battery condition issue but thought I'd share with you some of the data I've plotted for my car since picked up in late Dec 2021 for comparative purposes - consumptive (mi/KWh) data as provided by the PCM/MyPorsche app/Web site (itself being averaged for each trip) and a plot where i have recorded every charge the car's had in 1.75 yrs of ownership to date.

Suffice to say that as the majority of my trips are very short in and around Houston, the efficiencies or resultant mi/KWh and both calculated and 'predicted' ranges vary enormously.

That said I can however 'routinely' with only a slight variation in my driving style and/or trip length and/or charging cycles get back to decent 'guessometer' range predictions which as we know are totally dependent on recent driving history etc. - but perhaps the key difference to your situation. Just a ref case you might wish to compare to albeit from a 4S and not a Turbo S etc.

Aside: Note that for this year I have yet to attain the max. PCM predicted ranges I saw in the Summer-Fall of 2022 but still time before I can say anything definitive about that (suspect declingin Soh part of the answer) - however I definitely drove less long range trips this year which would impact that and the brutal summer (esp 3 months if insane evening temps) we've had has not exactly helped my overall HV battery Soh (very hot climates being possibly the single biggest detrimental impact on Soh preservation).

Plots 1/2:
Consumptive data reported by the car - of course again thee mi/KWh are averaged for each trip i.e. we do not get to see the min-max for each average:

Quite a large range in the data as one might expect - very crude data 'dump' i.e. simply plotted in order of occurrence and same for the 'calculated' range estimates based off these mi/KWh reported:

Plot 3:

AC and DC charge history with clear impact of seasonal prediction of max. range (for at home charging calculated from an 85% charge in Range and Normal mode with AC off).

EDIT - bit of overkill but forgot I had this older post too (I might edit this a bit if I had more time but good enough !


____________________________________________________________

Old post:

This chart uses reported kWh/100mi or energy used (Eu) in blue to calculate a predicted 100% battery charge (actual 83.7 kWh) range (Rp) in green i.e. of course this assumes constant level of efficient/inefficient energy draw from the battery:

So Rp = (83.7/Eu) x 100

e.g. 37.7kWh (my latest Eu number) would give a calculated range of 222 mile range. This is 23.6 kWh per 100 km.

a 60 kWh draw would give a range of 139 miles or in metric 37.5 kWh per 100 km.


This method of calcualting the range is of course biased towards extremely inefficient short trip data (based both on driving style and on my trip length-duration data). The predicted range data (green) calculated from the recorded per trip kWh’s used (blue) go from as low as 70 to a high of 250 miles with the bulk of the data between 160-220 miles. The longer range predictions here (230-250 miles) are clearly tied to the 10 or so longer (over 75 miles), more efficient trips and the chart just re-emphasizes that trip length and driving style have a fundamental control on any ‘predicted’ ranges whether based on the PCM post-charging calculation or as in this case derived from kWh per trip data and remaining capacity of the available 83.7 kWh battery.

The bulk of the ‘predicted’ ranges here are very low but these data must again be regarded as a more pessimistic use scenario i.e. they are based on scenarios which assume I would continue to drive very short distance/duration trips at low average speeds in Normal Mode with full AC for a full 83.7 kWh usage. The key point here being that you should not consider short trip derived range predictions as any useful indicator of your car’s ability to do far better during long range driving.

I can fairly confidently state that in my usage case that the combination of trip length and driving style are the principle variables controlling my range predictions vs impact of weather, terrain, load etc., as I have driven the car near 100% of the time with other parameters essentially fixed - they being:

AC on full,
21” wheels with summer performance tires
Texas low relief terrain (minimal elevation gains)
40:60 time between 1 vs 2 person load
Full seasonal cycle data
etc.

Overall my driving stlye can be described as ‘inefficient’ as I drive very ‘purposefully’ (not slow!), 90% in Normal/10% in Sport mode never using Range mode, always quick from a standstill, always with AC on, trip history dominated by short trips etc.

Interesting. My first 22to 23 was plagued with problems ( all of them it seems) second one arrived end March 23 has been faultless apart from dealer fitted Dashcam!

I have enjoyed driving my Taycan Turbo S for almost three years, and 30,000 miles. At this point, my car is in the dealership with an unexplained 30% drop in range. What really bothers me is that Porsche just doesn't seem to know and/or be willing to diagnose and determine the cause of a number of problems that I have had over the life of the car, and at this point I am incredibly frustrated.

The first problem I had was the dreaded 'red screen, stop the car in a safe place', and my car was completely down. Luckily I was at a stoplight, and I restarted the car and it was good enough to get to the dealer for an extensive 'software upgrade'. Then I started getting error messages from my Porsche charger, and it was shutting down during the summer months. (I have all the upgraded outlet receptacle, wiring etc.). I resolved that I will simply cut the charging current from 40A to 36A, and this seems to have solved the problem. How can Porsche sell a very expensive charger that doesn't meet its labeled specifications?? There is a class action that was started in March on this one. Then I've had the typical rattle, charging port stuck, and a few other minor issues - no big deal here.

What has become a big deal, is I've now had two very significant problems, and Porsche simply doesn't have an answer for me. Both of my rear tires wore down to the cords on the very inside shoulder with uniform treadwear (4-5mm on all treadwear markers across the tire, including the innermost marker.). The driver's side rear was worn so badly it deflated completely. My dealer tried to tell me this is an 'alignment issue'. The alignment on the tire that failed (complete separation of the tread/sidewall in the inside rear tire) was perfect. Again, for those of us who have seen a lot of tire wear, if you have a serious alignment issue that causes the tires to wear down to the cords, you will always see uneven treadwear when you look across the tire tread. Not the case here, and there are multiple examples of this reported, WITH DIFFERENT TIRES, so it is not a tire defect. No answer from Porsche other than 'we'll monitor the tires carefully'. Something is very wrong here. Again, alignment issue would present uneven treadwear across the tire - not the case for ANY of my tires, or the other tires that have experienced the same failure.

The second big problem is my battery seems to have lost about 30% of its range overnight after getting the car back from the dealer. I showed them a photo of my estimated range at 85% of 236 miles before I took the car in. After I got the car back, I got 170 miles at 85% under the same conditions - in my garage with the same charger, same weather. I also tried to fast charge the car (very rarely do this, but they left me a car with only 80 miles, and I needed more range. Plugging into a 150KW station, the car never requested more than 90KW. First time that's ever happened. The first input I got from my dealer was that it appeared to be a 'high voltage battery issue'. They only have 3 techs qualified to work on the HV battery, so after a few days, the tech got back to me and said all the battery cells are in perfect condition. He measured all 33 cell modules and all 198 cells and said they came out to 3.9Volts and 73% charge, so the cells are all balanced and have correct voltages. I'm not sure why they were only 73% charge.

The dealer is trying to tell me that everything is fine, and that they charged the car to 100% and got 222 miles in Range Mode, which is evidently within the acceptable specs. I just checked via Porsche Connect, and my car is showing 190 mile range at 96% which equates to 198 mile range at 100% charge. I have never had less than 200+ mile range at 85% charge in my three years and 30K miles. There is clearly something wrong, and I am getting quite frustrated that Porsche does not seem to be capable of diagnosing either my tire or battery issues. I will say that the dealer is doing their best, and I have a very good relationship with them. This series of problems has really soured me on the car though - it's a shame.

Good evening

tire failure. :https://www.auto123.com/fr/actualites/amp/rappel-audi-porsche-32000-alignement-suspension/68936/

Recall of Audi And Porsche cars because of a suspension default and then a mistake at the recall forgetting to ask to control also alignment and camber

just look at the forum Catastrophic tire failure

Range can be modified when at Porsche Center keeping Taycan in operational mode without making any mile modifying the result of range calculated by its computer. That can be also reduced if you keep on automatic Clim

so you should wait a few time with your own way of using your Taycan to see if the range will increase

in my Porsche appli you can also control the power consumed day per day so you can see the KWH/100 miles used when your Taycan was at your dealer if they made a test of a few Miles.

if it’s far upper to your average it will reduce your range remaining just after.
I’ve had the same issue at the delivery of my taycan and after 500 kms the range wins 30 kms
Take also care to control without Clim wich may reduce more than 10% your range.

sorry for my poor English
Hope it can help you
Gilles

Many thanks for the multiple replies with data and information - incredibly helpful (thank you ciaranob, Torv, and daveo4EV). I have ordered the OBD tool. I have to give a special thanks for giving me the advice and contact information for Simon, the head of Porsche NA Customer Relations. After my dealer saying they have no way of determining the actual KWH of the battery, and that they will return the car to me, and I need to drive the car to 20%, let sit overnight, then recharge to 100%, they have taken a different approach. This happened after I emailed Simon, head of NA Porsche relations. The fact that my battery depleted 13% in 3 days of inactivity, with 5% depletion overnight has possibly caused them to decide a number of additional tests are necessary. I have to believe that all of this is coming from Simon. They are also taking into account my 10 years of multiple Porsche purchases, my somewhat OCD charging and driving habits. Also my 15 years of racing Porsches was mentioned. Possibly because I race, I am incredibly easy on my street car and its components. I rarely accelerate hard, and try to anticipate things so my braking is minimal, and I can coast for the maximum time (my Panamera GTS went almost 100K miles on the original pads and rotors). They have decided that they will discharge the battery to 20% themselves, and run a number of additional tests. I'll keep everyone posted.

 

[daveo4EV]

the loss of percentage for _NO_ reason while the car is idle is the _MOST_ compelling data/problem in the list - the fact that the guess-o-meter is all over the place never convinces me personally of anything with an EV - it's too easily mis lead/reset/wrong - for the same reasons range on my GT3 says I can't go more than 80 miles on a full tank after a day at laguna seca…but then after some normal driving gas range for my GT3 is well over 360 miles (also wrong)…

the dealer can determine the "health" of the battery by getting the SOH dala - State of Health - that will show/demonstrate what the car "thinks" the useable battery capacity currently is - and that is the one of the pieces of data Porsche itself uses for diagnostics…

I hope we get to the bottom of your issues - the Taycan's too good a car/EV to have technical issue cloud it's reputation.

Ive had mine for 15 months now. 2021. had All your problems including tyres. as you advise dealership always come back with everything is good. as you say they just don't know ,, I've not had range issue as mine has only ever seen 245 miles range although air con together with heating packed up in December. this was a known issue with parts on back order briefly. totally amazing car. its a keeper.. Dealership not used to increased throughput it seems, reception in service border on rude. did have its 2 year service. following day they rung me to advise wiper blades may now need replacing as car had alerted them on sweep count ,,,,,,,,,,not all bad then.........................

 

[Vim Schrotnock]

Well - just got the word back that I have a bad cell in the battery. They had to drive the car down to 10% to get the error message, and now it won't clear. They have contacted Porsche in Germany to see if this is a 'repair or replace' situation, and I'll know in 48 hrs.

Your issues seem to be exactly the same as my car has. It is now with Porsche service and they should have the diagnostics tomorrow. The have already contacted the factory to get advice. My car would not restart even after a few hours rest or a 12 volt reset.

At present my car is showing 87% SOC but only 173 km range???

Took a long time for them to diagnose your car though?

Hopefully your still just under that 3 yr window for a full warranty fix?


Excessive Loss of Capacity

If a capacity measurement performed at a Porsche authorized dealer shows, at the times specified below, that net battery capacity is less than the percentages specified below (the “Warranted Value”), any percentage that falls below the relevant Warranted Value constitutes “excessive loss of capacity”:

• 100% of net battery capacity on the date the car is first delivered to the first retail purchaser or the date it is first used as a demonstrator, lease, or company car, whichever comes first.

• 80% of net battery capacity within the first 3 years/37,500 miles, whichever occurs first.

• 70% of net battery capacity within the first 8 years/80,000 miles, whichever occurs first.
