Problems with new Leon 2021

[mn66]

Hi,

I have had my new Leon for just over a month now and I've noticed several problems, and the dealership I bought it from don't seem to be much help.

I am hoping that someone may confirm or debunk some of these problems are actually "normal" behaviour.

Here they are;

• There seems no difference between Normal and Sport modes. With my mk3 Leon I could definitely tell the difference
• If I disable the lane assist it always gets re-enabled when I switch the car off and on
• The heating sync button doesn't stay on. If I change the fan speed or temp, the sync button disables
• Sometimes I have to press the screen buttons numerous times before they work

I have tried to update the infotainment system software, but haven't had any luck doing so.

Thanks in Advance
Stay safe!

Mark

Lane assist behaviour is normal, but can be changed with OBD11. I haven't noticed the other issues in my car.

You're not wrong about the Sport mode either. Mine turns the power steering off and is very noticeable.

Thanks very much for the replies.

Pardon my ignorance, but what's OBD11?

So, the dealership are lying to me when they say there is no difference between Sport and Normal modes

 

[Seriously?]

Don't you just love it when dealerships either know nothing about the product they sell or just tell you any old bull to get rid of you?
Would SEAT really go to the trouble of adding a function button that does nothing?
From the SEAT website; maybe print it off and go and take it to them to read and learn!:

I know! this is what makes me mad! the way they're your best friend when you're buying the car, then want nothing to do with you afterwards!

Thanks very much 'seriously?' for the reply and the link

No worries; obviously some functions will vary model to model as the link is to the generic description. Pages 234 and 235 in the latest version of the Leon manual gives much more detail

If you alter the settings on the MK3 for the right hand side of the car it disables sync, I'm presuming it's the same on the MK4?

It is. To change both driver and passenger side at the same time, adjust the passenger side control

Pardon my ignorance, but what's OBD11?

OBD 11 is a bluetooth dongle that connects to the cars diagnostic port and allows you to read fault codes and alter software parameters. There are other similar tools like VCDS, VCP, OBDAPP and probably lots more. Unfortunately VAG has introduced an extra layer of security in the never cars, so a lot of control modules are locked out for most users, but the lane assist is one of the modules that are still open

I've had my Leon ST hybrid for six months now. Generally I'm very pleased. Most days I run only on electricity. Longer trips give about 54mpg on petrol.

I read the manual but I felt the style of writing told you how to do something but didn't explain what the effect would be or why you would want to do it.

I wanted to have a towbar fitted for my bike rack but this wasn't possible (recently I discovered that there are options but not through SEAT) and I spent a lot of time trying to find something that would work because there's nothing that will hang off the back either.

The car wasn't on the list of vehicles for which a £350 OLEV grant was available and I spent ages explaining to SEAT Support that they were looking at the wrong set of criteria on the Govt website. They said they were working on it but I gave up on them after a couple of months (they still haven't done anything) and paid full price for a charging point (EO) at the end of my garden that takes electricity from my solar panels. I don't get why SEAT have been so lazy about this. The Skoda hybrid is there, Golf and Passat are there, plus any number of Volvos.

The default of Lane Assist being switched on is at odds with the guidance in the handbook of only using it on motorways (I don't live by a motorway so I need to change it every trip) and I wish it wouldn't constantly default to ON.

Occasionally, the display that "reads" road signs and shows the speed limit switches to 90 kilometres per hour instead of showing a speed in miles per hour.

The infotainment touch screen is quite hard to use because to get the right "touch" and accuracy you need to rest your hand, and you then tend to rest your hand on the volume controls. Voice commands work but only if you know the format, and they don't react to "turn off Lane Assist!".

The GPS is good, but how do you delete a place you no longer wish to see on the screen?

When the car's wet, I always get wet trousers when loading the boot. Sometimes my phone will charge, sometimes it won't.

Having similar issues on my five week old PHEV. Sat nav has frozen twice and the sync function for heating keeps reverting back to individual when you adjust one side.

unfortunately the dealer is struggling to answer a couple of new owner issues. Is it normal for the rear light bar to illuminate when charging? The handbook seems to indicate that the electric mode will only operate at temperatures above 10c which means that for a couple of months each year it’s redundant.

Other than that great car.

 

[Deleted member 123864]

Which side are you using to adjust the heating expecting it to keep in sync? You should adjust the passenger side to adjust both.

 

[Keith Roberts]

Thanks, mever Noticed that info in the handbook. Just reverted to my method from the Mk3.5 cheers

The infotainment mobile WiFi in mine works great until it decides it doesn't want to work. I try to see if there is anything online that I can do to fix it, major pain in the hearse

I also have a problem with my Leon 2021 5D .
Problem with the screen that sometimes does not turn on is freezing especially when is cold weather

I don't know but new leon 5D has a lot issues and problems and poor quality previous Leon 5f was much better

I'd second the opinion to not buy this car. I have now had the car for just under a year and I've another 2 to go cant come quick enough, I even compare my first cars the Ford Cortina,Fiesta and Vauxhall Cavalier and I'd gladly take any of these over the Leon

Nope not a car I should advise anyone to buy. So many problems in one year and many isn’t possible to get fixed.

Yeah this is my 3rd Leon and you'd think the new one would surpass the outgoing model which it doesn't. A wee bit of advice if your looking at getting the Mk4 don't the Mk3 is a better car IMHO I'm sorry I couldn't extend my lease for my Mk3.

To provide some balance in opinions - if you exclude first year cars (i.e. up to to last summer approximately) there are a lot less issues with the new builds. Yes, software is still buggy, but that generally doesn't affect functionality of the car. Considering whoever orders now will probably get it in 2023 - those will have both software and hardware updates...
