“I have an 03 mercedes E500. At about 65000 ml I had glycol in my transmission due to radiator failure. I took it to mercedes sarasota and they said it will cost $5000 and they have to change the radiator and the transmission. I was reading the mercedes world forum and I see that lot of people had the same problem. At the and cost me $3000 at aamco. I hope mercedes will issue a recall for this problem.”

“In june of 2010 I purchased a 2003 mercedes benz E500. The car at times would shift heavy and at times would shift down suddenly or accelerate suddenly and dramatically when the accelerator was press lightly from a stop. The problem continued to the present time and has gotten worse now in the winter months. I know the car is a potential danger but have no other alternative but to drive it. Please help!”

“I purchased a 2003 mercedes benz E500 which was out of warranty. Shortly after purchasing the car my transmission started losing power on the expressway and making a loud roar from the back of the car. The car then started stuttering while at 60mph which posed a danger to myself , my family, and cars around me. This problem almost caused cars behind me to hit me because of the sudden loss of power. I immediately took my car to the shop and it turned out that glycol leaked into my transmission due to a faulty valeo radiator in my 2003 mercedes E500. …”

“The original radiator for the 2003 mercedes benz E500 leaks coolant into the transmission and torque converter, causing the car to jerk and jump. The coolant in the transmission acts as an containment and ruins the transmission and torque converter, which later will need to be replaced, along with the radiator. These three major part including gaskets, hoses, and labor are extremely expensive. Nothing has been done to correct this problem. The dealership is stating that the only thing that can be done to fix this problem is to replace all three components at owner's expense.”
