I spoke with my dealer today and they said they've had quite a few doors replaced, including one customer who required both doors replacing, and they said Lotus havent pushed back at all. There was one very early on whereby they asked for it to be transported down to Hethel for inspection but since then they've just authorised the replacements. I guess they've accepted that this is a problem and now just authorise it.
Resistor packs on the air con is also a common issue with a good few cars having to had them replaced.
They're collecting the car from my house and asked if I wanted a transporter (at my cost) or would be happy with someone driving it back ot the dealers.
