Our car is not alone at the dealer with recent radiator failure, they have several other CX cars awaiting radiators. Our car has had one radiator fail before the swirlpot was fitted at 2K miles and one radiator fail after the swirlpot at 3.5K miles. I am hopeful the final fix is the ECU flash, as it appears its the ECU on the CX generation that control how the thermostats open/close.
