Six problems related to engine and engine cooling have been reported for the 2007 Mercedes Benz S550. The most recently reported issues are listed below.
I brought a car from a car dealer in tampa florida and when I got the car I noticed that the car would not pickup speed after pressing the gas pedal and it was asking me to turn off the engine or it will fail . Also when I tried to put in coolant. I seen a milky substance that was coming out of the hoses and in the overflow tank of the coolant reservoir which indicates issues with the heads or head gasket . Also the title I got says salvaged which I asked if there was anything wrong with the car and the car dealer told me no . Never disclosing that the car has been salvaged . There are other issues with the car that I forget because of so many issues with the car that I cant keep up with and I want to return the car to the car dealer and get my money back and have tried but they refuse to make good on the sale.

I was driving my S550 and came to a red light. I stopped at the light and when it turned green, I took my foot off the brakes and pressed the accelerator, but there was to response to pressing the accelerator. The car rpms were increasing but the vehicle was crawling at less than 5mph. This led to me pulling over and parking the vehicle and turning it off. I waited 5 minutes and then restarted it and it began to work normally. The second time this happened was while making a left turn, I pressed the gas pedal and there was no response and the car was reving but traveling less than 5 mph with oncoming traffic having to stop short to prevent crashing into me while I was making the left turn. This was again resolved with me parking the vehicle, turning it off and then restarting it. After the second time this occurred out of no where I decided its a very dangerous safety issue.
