My straighteners are now 8 months outwith warranty, Dyson have advised me that they are non-repairable. They won't hold a charge for more than 5 minutes. Dyson have offered me a 25% discount on a new set or £99 for a refurbished set. I'm so disappointed that they aren't standing behind their product and that they feel less than 3 years is an acceptable lifetime for such an expensive item. This appears to be a well reported and common issue with the straightners. I will not spend another penny on any Dyson products.
