Hello fellow Rennlists,

I want to purchase a Cayenne S, but I want to ask whether I should go for the e-hybrid version. I want to keep the vehicle as long as possible, but I am afraid that the e-hybrid will be a nightmare to maintain down the road. I have looked at the reliability, but not much information is available. I always hear stories of people keeping vehicles with e-hybrids and having to replace the battery for a lot of money.

I wanted to listen to the community's opinion before purchasing. Lastly, I would like to know if I should wait for the Cayenne GTS facelift as, based on the forum, it is a few months away. Thank you guys

For a long term hold, I'd avoid the hybrid.

It will lose battery capacity every year just like your iPhone when you check in battery health. I wonder why Porsche doesn't have the same app data as Apple?

Pure ICE for the win

Porsche gives an 8-year warranty on the high-voltage battery. There is no reason to be afraid of a hybrid.

I think you should just choose with whatever makes you feel most comfortable.

I wanted an S, but went an e-hybrid. Where I am located, further and further restrictions are being imposed on petrol guzzling cars (both in terms of taxation and petrol prices). The cost and restrictions of owning a petrol car in 5, 7 etc years will be worse than it is today. Will such costs and restrictions adversely affect resale value? Will that outweigh any costs of maintaining an e-hybrid? My guess is 'yes', but I could be wrong. I am taking a gamble.

Reasonable minds may differ on this. So just go with your gut I say!

Porsche has been producing hybrid vehicles for many years. Does anyone have access to actual empirical data?

the forums don't seem to be filled with hybrid horror stories, but maybe I'm missing something - longevity of the hybrid components seems to be on-par or even better than mechanical elements for similar age and usage…

but I welcome links to forum posts or otherwise

Call the dealer service department and ask about the parts + labor cost for hybrid battery replacement and report back.

FUD - pure FUD - the battery warranty is 8 years/100,000 miles - so that's going to happen when - and why?

and batteries do not tend to "fail" outright for the big hybrid battery - you lose capacity over time - but it's still operational

after the 8 year/100,000 mile warranty on the battery replacement/repair cost of _ANY_ Porsche drive train ICE component or otherwise is probably eye-watering in terms of expense.

you should know the costs no-doubt but this again is only an issue once you reach 2032 and do you keep your Porsche's that long - you're much ,more likley to have to pay to fix an AWD transfer case issue 5-6 years into ownership vs. a battery issue post 8 year warranty - I'll wager anyone they will have more problems that are more likely for the shared mechanical aspects of the Cayenne and it's complex suspension, transmission, high performance ICE motor vs. an EV motor and battery issues…

there is sooooooo much more to go wrong between the 4-8 year period that is NOT covered by warranty that also is much much more likley to have wear issues and need repair or replacement - 1000's of mechanical and moving and wearable parts outside of 4 year warranty period that will need to be serviced.

I have asked my dealer as to battery costs and frequency - to date all hybrid battery issues my dealer has dealt with have been warranty issues…

Hendrick Porsche in Charlotte, NC says “Hybrid battery replacement costs can range anywhere from $2,000 to $8,000.”. See below.

i understand that they have an 8 yr warranty. Assume that the battery fails at 8 yrs and 1 day. Using the high end 8k, above, that’s less than $85/mo. I might save that much in gas.

how many other Porsche drive train components cost $2000-$8000 to fix/repair/replace after 8 years? I'd wager _A LOT_.

Comparing Gas vs E-hybrid longevity is senseless.
All the e-hybrid is on top of the gas engine .
So you have a complex engine with a lot of parts , on top of which you put also a complex e-hybrid module.
Based on this , e-hybrid can be equal or less in terms of longevity , than a normal gas version.

This is why I opted for a 2024 Cayenne S . No mild hybrid , no batteries , did not spec the PDCC which adds the 48v system. Keeping things simple is always a good option .

This! less tech, less frills = longevity

comparing a cooled, controlled pack with buffers and much lower c rate during charging to an unconditioned disposable phone battery? Please stop giving advice on hybrids.

Also, ask them how often this is needed. Vs replacing transfer cases, cardan shafts, $3,000 lithium 12v batteries, blown turbos, oil leaks that require the entire front subframe and engine to be dropped, etc. See what that frequency distribution looks like.

I’ll wait.

Needsdecaf

Hmm, try considering another way of thinking. In 11,000 miles of driving, my ICE engine has run less than 4,000 of those. And those 5-6 mile round trips to the grocery store? The ones that never allow the oil get up to temperature and let all kinds of crud build up in the oil? Those are done in pure EV. Engine never turns on and short cycles.

still think I can’t have better longevity?

southernpaladin

Exactly this. And what is the market going to be like in 5, 7 or 10 years time for a v8 in a family car?
