Christ, dealing with Lotus CC has been painful.
After 4 weeks of almost daily phone calls with them I've got nowhere. No one I have dealt with has been able to tell me what the cause of water ingress to the harness terminal was or whether it would happen again. I "politely" pointed out to them that if this happens every 6 months because of a design/manufacturing issue it makes the car worthless. The repair is not trivial at 35 hours of labour and stripping the car down. They finally came back today with a valuation for my Emira as part exchange for a new one. Needless to say I wasn't happy with it, particularly as I was offering to buy a new car to resolve the situation. To be honest, given the financial hit to me of not having the car for what would be 6 weeks, I felt like they were taking the piss.
HOWEVER, I called B&C (who are brilliant) to discuss the technical ins and outs of the issue and discovered that there is now a recall for this which is linked to the water getting into the HVAC as discussed at length elsewhere. I have also had the HVAC resistor replaced because of water ingress last year. I strongly recommend that any of you who have had the HVAC failure and replacement to get the terminal assessed for corrosion.
It is so frustrating that Lotus CC could have told me that there was a fix and recall in place at the start of this. I've been chasing them almost every day which has been an enormous waste of time. At no point did anyone say that this is a known issue, it is not a one off, and that a fix is coming or already issued. I'm torn on whether this is due to incompetency or dishonesty.
So rather than being fair with me and selling a new (probably orphaned) car, they will now be spending thousands on the hire car they've given me.
