general problems of the 2003 Mercedes Benz E320

Car is used only for work and mostly highway driving for appointments. At 70,000 miles the transmission went out on the E320. An investigation reveled that a valve had failed in the radiator causing coolant from the engine to mix in with the transmission fluid which in turn burnt out parts in the transmission. Also there is hesitation when stepping on the gas pedal the car sometimes sputters to shut off when stopping.

My 2003 mercedes E320 had less than 40,000 miles when the the transmission and struts started to present problems. The dealer was able to make repairs under warranty. Now at 78,000 miles, I'm being told that I need to replace the parking prawns due a leak in the back of the transmission. The bushing on the left side also needs to be replaced. I just had a bushing replaced about 6 months ago, which was a bit pricey. When they replaced one of the bushings under warranty a few years ago, they should have replaced all of them. I have encountered numerous with this car. I purchased it with only 37 miles on it in September 2003, but replacement of a number of parts while under warranty now leads me to believe that this car was a lemon from the beginning. Is it normal to have the air pump replaced at 73,000 miles? again, that was a pricey repair -- $1100. 00.
