Faulty Mercedes Benz radiators

I own two Mercedes, an '02 Kompressor and an '03 CLK 500. IN THE SAME WEEK the radiators on both had the SAME PROBLEM: coolant glycol leaked into transmission cooler causing the radiators to be replaced, transmission systems flushed twice and convertors to be torqued. MB states there is no recall on the radiators and this is not a common problem. Have other MB owners had this problem?

CR has no problem areas in engine cooling or transmission for those years. You might just be unlucky…
