My Dyson corrale has recently developed an intermittent fault whereby as soon you start to use it  after it's been fully charged and the device has heated up whilst being docked, it immediately flashes that the battery is low and then switches off.

If you turn it on again and allow it come to temperature it will show the battery's full and will work, although even when it does work it struggles to last longer than 10mins and using 'hybrid' mode isn't much better.

As its still under warranty for another 2 months, I contacted Dyson via the live chat and they offered to exchange the unit which sounded great.....until they advised there would be a cost of £99 to exchange my faulty unit with a refurbished one?

When I questioned why I would have to pay for the exchange even thought I am still within the warranty period, I was just advised that it's the best they can do and back office advised it's due to 'matured warranty', whatever that is?

I can only guess its because I've only have 2 months left since the warranty is due expire so they feel I should be penalised for this.

Has any else had a similar experience with a 'matured warranty'?

Is there any email address for customer service that I can escalate to?
