I HAVE A 2004 MERCEDES C320 THAT INCORRECTLY THOUGHT THAT IT NEEDED TO CUT POWER TO THE VEHICLE WHEN I WAS TURNING TO THE LEFT.

I HAVE A 2004 MERCEDES C320 THAT INCORRECTLY THOUGHT THAT IT NEEDED TO CUT POWER TO THE VEHICLE WHEN I WAS TURNING TO THE LEFT. IT DID THIS SEVERAL TIMES, I WOULD GUESS ABOUT 6 OR 7, FROM THE TIME I LEFT MY HOUSE UNTIL I TURNED AROUND AND PARKED IT IN THE GARAGE LESS THAN 1/2 MILE DRIVING DISTANCE. THESE WERE NOT ALL COMPLETE LEFT TURNS, MOST WERE CURVES TO THE LEFT. MY WIFE TOOK IT TO THE DEALER LATER THAT DAY, AND DECIDED NOT TO HAVE IT LOOKED INTO BECAUSE IT DID NOT DO IT TO HER AND "THE CAR WAS PERFORMING AS DESIGNED" ALSO SHE DECIDED SHE DID NOT WANT TO PAY FOR A DIAGNOSTIC THAT WOULD NOT PRODUCE ANY FAULTS. IT HAS NOT DONE IT SINCE, ABOUT 2 WEEKS NOW, BUT I CONTINUE TO BE CONCERNED THAT IT WILL RECUR IN A MORE SERIOUS SITUATION. THE DEALER KEEPS SAYING THAT THE CAR IS WORKING PROPERLY BECAUSE THE WARNING LIGHT CAME ON AND THE VEHICLE CUT POWER AS IT SHOULD WHEN IT DETECTS ONE OF SEVERAL CONDITIONS THAT WOULD CAUSE LOSS OF CONTROL. THE ONLY PROBLEM WITH THIS IS THAT THERE WAS NO CONDITION TO CAUSE LOSS OF CONTROL. THE TIRES WERE NOT ABOUT TO SPIN AND THE YAW OR WHATEVER IT IS WAS NORMAL. THE DEALER ALSO KEEPS SUGGESTING THAT I DISENGAGE THE ESC IF I DO NOT WANT IT. I THINK THIS IS IRRESPONSIBLE ADVISE, THE ESC IS A VERY IMPORTANT SAFETY DEVICE THAT I DO NOT REALLY WANT TO DISENGAGE, BUT I ALSO DO NOT WANT IT TO ENGAGE INCORRECTLY IN A CRITICAL SITUATION. *TR

I OWN A 2004 MB C320 AND I HAVE NOTICED THAT WHEN IT REACHED 40,000 MILES THE CAR ITSELF STARTED MALFUNCTIONING FROM THE REAR WINDOW SHADE WOULDN'T GO DOWN FOR WHICH I ONLY USE OCCASIONALLY; THE AIR CONDITIONING WOULD TURN ON AND OFF; THE TEMP GAUGE IS INACCURATE; THE PASSENGER VISOR CAME OFF; THE CENTER CONSOLE WOULDN'T SHUT CLOSE AND THE. I WENT TO MB FOR THE YEARLY SERVICE- APRIL 2009 AND THEY WANTED $1300.00 FOR THE WINDOW SHADE; I THINK $500 FOR THE CENTER CONSOLE AND $125 FOR THE VISOR. AND THEY ALSO WANTED $800 FOR THE DIAGNOSTIC CHECK FOR THE BLOWER AND I HAVE TO PAY WHATEVER PARTS THAT NEEDS REPLACING. NOW THE CAR IS ALMOST 60,000 MILES AND THE CHECK ENGINE LIGHT CAME LAST WEEK. I NOTICE THE LIGHT COMES ON WHEN I START THE ENGINE AND IT FAILS TO TURNOVER. THE CHECK ENGINE LIGHT WOULD EVENTUALLY GO OUT. THE SAME THING HAPPENED AGAIN YESTERDAY WHEN IT DIDN'T START THE FIRST TIME, THE CEL CAME ON. I CHECKED THE GAS CAP AND IT LOOKS TIGHT TO ME. I HAVE ALSO NOTICED THAT THE RADIATOR WOULD MAKE A VERY LOUD AND UNUSUAL NOISE WHEN THE CAR IS STOPPED. I THOUGHT I MADE A RIGHT DECISION OF BUYING A MERCEDES BENZ DUE TO THE FACT THE CAR HAVE A GREAT REPUTATION. WITH THE ECONOMY NOWADAYS AND THE AMOUNT OF MONEY THE MB SERVICE ARE CHARGING I THINK IT'S RIDICULOUS FOR A FAIRLY NEW CAR. *TR
