Engine And Engine Cooling problem #1

Bought this certified Cls550 from keyes european mercedes in van nuys,CA on 11/23/2009 with 42000 miles as soon as I got the car home I noticed the fan was overly loud and my temperature gauge was reading 110. Called dealership they said fan motor on these cars are all extremely loud and temp. Sounded okay. Two weeks later I was driving when I was alerted to turn off engine immediately due to car seriously overheating. Dealer said it was the thermostat bad on car. Also been having trouble with the transmission since I bought car. Keep in mind I have only had it for about 47 days now. The same time thermostat was replaced they said a component in the transmission was bad and replaced it. Have had my car back for 4 days now and the transmission no longer slips, but is jerking hard into beginning gears. Will be taking car back to be checked again!.

Engine problem #2

Catastrophic failure with sudden loss of power and inability to proceed at more than 20 mph. It has now recurred twice and vehicle flatbedded to agency. Has been in shop for six days with no repair. Service manager denies that this is the second failure because his diagnostics were unable to determine the problem the first time.

Engine Clicking And Tapping Noises problem #3

Every time I fill up my tank with gasoline, once I park in the garage, the garage is filled with strong gas fumes from my car. I checked for leaks under the car and found nothing. I have to raise the garage door to let the fumes out, due to getting lightheaded from the fumes. The fumes remain with the car for 7-10 days. This has been going on for the past four years. This problem is a danger to my family's health!!!! surely, there is a recall on this problem! 2nd issue: I turned my car off and the fan kept running. I noticed that the fan was so loud that it sounded like it was about to blow up. Black smoke came from under the hood. I went on into the building to my meeting for an hour. When I came back outside, the fan was still going and still loud. This had never happened in the five years that I had the car. The car would not start. I had to call someone to boost it off to start. I then went to the shop to check to see if I had battery or starter problems. No problems found in either. This has happened twice since then. I am afraid that the car will catch fire with me in it or my family or friends. 3rd issue I was driving along and the dashboard read out in red to stop the car . . Vehicle is too low. . . When stopped, I noticed that the passenger side of the car was low and the driver side is raised high. I have to sit there for a few minutes until the red lights went out. This happens often. 4th tire pressure light stays on. I took it to check on pressure, it was ok. I did not need new tires either. The yellow light stays on and this week the red light popped on and will not go off. 5th the check engine light stays on and mechanic can not find the problem. 6th steering system loud popping noise when I back up or turn steering wheel. It used to be random but now it is every time I drive the car.
