cupra leon 2021 hybrid electric drive not working properly
- Thread starter azzedine2005

Good luck
My car had this and on initial inspection it seems to be the battery coolant leaking all over the batteries. Tomorrow my car will have been with the dealer for 4 weeks and is still awaiting a more thorough examination by the master technicians.
Will this be covered under warranty is the question that has still yet to be determined. At the very least it's probably going to need the batteries replaced, but others with similar have had to have the batteries, electric motor and engine fully replaced.
Just to diagnose the problem (if not covered under warranty) is going to be £470. The fix is potentially looking at almost £10,000 if all those components need replaced, the question is still unanswered, who is picking up the bill, me or Seat.
It's worrying times.

i was considering a mk4 mild hybrid as they are starting to reduce in price , but reading stories like this is worrying the phev is one to avoid though agreed doomed to fail eventually at least with the mild its a small unit under the seat probably loads on ebay already from scrap cars
If only you had not bought the Hybrid, you would have been fine. I too went from my Mk3 with a lot of apprehension, but once I got the infotainment set up mastered, the Mk4 is a great car (with ICE). Still would not have any EV of any sort though.
The mild hybrid is a good compromise, in comparison to the PHEV, replacing the starter motor with a bigger alternator and only a tiny battery - it makes a big difference to the fuel economy without being really noticeable otherwise.
It's only six months old so no proof on reliability, other than my last Leon already had three warranty repairs by now.
But it did do 53mpg from delivery - my last Leon with the exact same engine, but no mild hybrid, did low forties until it had 10k on the clock.

3 warranty repairs in 6 months ? 53mpg in mixed driving ? what`s the mpg round town ?
Well one was a safety recall but yes, the 2021 model was a lemon and still had several faults (mostly software) when I thankfully got rid.
No idea about the town mpg, I live in the middle of nowhere, but what ever you get from an ICE should be at least 10% better if you use the mild hybrid correctly i.e. let it regen as you slow down, lift and coast etc.

My last Leon had no faults in the 8 years I had it from new, and my current 2 year plus Leon has only had the engine cover debacle and the heat shield needed checking (done at service and was ok) so you must have been unlucky.
Possibly but all the MK4 cars in the first year or so of production had issues with SOS, infotainment bugs and other faults (like this post on electric drive for plug in hybrids), some required hardware replacement and others with software updates.
After my MK3, which I really liked, it was a shock to have to live with such a car for three years until the lease expired, if I was buying one myself I'd avoid anything made before 2022.

Mine was delivered in May 2022, so all the bugs must have been sorted by then. I remember someone told me years ago never to buy a brand new model, but allow a couple of years till all the faults had been rectified.
I always thought it a good idea not to be an 'early adopter' and anything tech-based; get the gremlins sorted first.
Is there an average build date when all the problems were ironed out on the mild hybrid cars ? as i am looking at a few 2023 to 2024 cars but part of me is saying these cars are long term unreliable. my 1.8 mk3 has been utterly reliable other than the thermostat housing and a cheap rain sensor and fuel flap motor diy replaced
