2021 Seat Leon - front and side sensors suddenly stopped working, complete with dash message advising to try cleaning them (I have) and also that emergency braking system is not available and also blind spot notifications not working.
Dealer has advised the sensors need replacing and that they are not covered under warranty - could this be true? No known damage to any part of the car…

New car warranty, or extended/approved used?

New car warranty (inside 3 years)

I would ask the dealer to explain in writing why they assert it is not covered by warranty and direct you to the relevant terms(s) within the contract.

You could also take it to a different dealer for another opinion. They might just sort it under warranty.

Can’t comment about the braking system and blind spot notifications not working but if you are referring to the parking sensors then assuming they were fitted to the car when new they would be covered for 3 years under warranty.
If they were added afterwards to the car but still Seat supplied and fitted then I believe the warranty is only given for 2 years on them.

Yeah I think they are saying because it’s damaged the warranty doesn’t cover it
Reading around the front ones can be prone to stone/chip damage
Next closest dealer to me can only look at on 17th October!
Just to add it is a lease, which is due to go back at the end of October so not sure whether to just leave it

Blind spot radar on my old CLS was covered by the dealer third party warranty with no questions asked.

It’s part of the driver information systems, which are generally covered.

It’s reasonable to expect any electrical component should last three years on a new car, shoddy behaviour on Seat’s behalf.

Can you see any external physical damage? Seems unlikely if it is side as well.

Don't think you will get away with leaving it, the leasing company will discover it on the return day or shortly after. Pursue for warranty definitely, it's what you are paying them for. Put it all in writing obviously.

I suspect its one of the blind-spot radars rather than the parking sensors (which are used for short proximity parking rather than blind spot/forward alert). Have the dealers read the fault code properly?

Yeah I have it in writing etc now
There is damage (scratch/stonechip) to a single front sensor
The dealer has said that takes the entire system down - something about if one sensor is out then the system can’t trust it so it all turns off
Their fix is to replace the single sensor

get someone to stick a diag tool on it.

Sadly seems fair enough.

Any damage to the part (in this case sounds like a stone hit it) would mean a fault isn't "manufacturer defect"

Much like a windscreen crack from a stone isnt really down to the manufacturer
Yeah agreed

Now to find out whether the lease return charge is less than the dealer repair…

This is correct

Deffective part = warranty
Damaged part = customer payment

It wont take long to replace 1 sensor.
The problem will come from the Garage not being able to buy 1 sensor as it will only come as part of a complete wiring harness.
That where the cost will come from.
You will be paying somewhere around £300-500 for it when if they could get just the sensor it would be £50.

Jesus wept.

How do you think they've decided which sensor is giving the false readings? Then looked a that sensor specifically, and found it has external damage?

By examining tea bags? laugh
I've seen a few iffy sensors on vag cars - never seen it take out blind spot and brake assist. I've just seen it give a warning for the segment covered by that sensor.

This is good advice. When we returned a car to BMW finance the charge for bodywork damage was about half of what it would cost us to have had it repaired.

While you'll get warnings about all the systems not working, they will still work in functions where that particular sensor is not required.

AEB relised on parking sensors in some parking-speed related situations, and sometimes for pedestrian/cyclist intervention (depends on car/system). This would not mean that your AEB vs vehicle would not activate. If that function of AEB relies on the forward facing camera rather than the parking sensors, it'll still work.

In the same way that you might get an ABS light for a whole bunch of reasons, but ABS would still work as best as it can even with a fault in the system. Generally these systems don't just "turn everything off", even though the warning suggests they might. They will work with what they can. Obviously all this depends on the particular car and system, it's not alwasy consistent...


How much is the replacement sensor from the dealer? They should be able to swap it fairly easily - it may not even need coding, just clear the codes (i had a sensor go in my Tiguan - hit a tree branch - and a £10 ebay job clipped in and worked fine after clearing the errors).
