Wait a minute......., I’m sure the OP tells us that Morgan has paid for the repairs, all he’s not pleased about is that they haven’t explained the cause.
If this is the case, I think the OP is being less than fair towards Morgan, I would expect to pay for the repairs myself on an eight year old car.
Since he’s not going to buy another Morgan, I wish him good luck with all the other brands, Id recommend KIA next time, seven year warranty might just be enough.
