Coolant Leaking problems of the 2003 Mercedes Benz E500

Recently purchased this 2003 mb E500 while driving along the vehicle began to stutter and shake @ around 1500 rpm, this occurred continually. Made it home and googled this problem and found out that this is a common problem for this vehicle due to a leak in the coolant system that somehow gets into the transmission,causing it to become contaminated which produces this fierce/potential dangerous stutter/jerking. To my surprise, Mercedes Benz is fully aware of this hazard and has not had a recall/bulletin to fix this common problem, leaving this expensive repair cost on the consumer. The vehicle cost is expensive enough and to have to make this costly repair is unfair.
