THIS CAR IS A MONEY PIT! I BOUGHT 2004 C230 KOMPRESSOR USED IN 2007. TO DATE I HAVE SPENT WELL OVER $8500 IN REPAIRS AND THE CAR IS SITTING IN MY DRIVEWAY WITH ITS LATEST AFFLICTION..A COMPLETELY BLOWN ENGINE. IT IS A USELESS PIECE OF JUNK AND I AM OUT THE $25,000 I ORIGINALLY PAID FOR IT, PLUS THE ADDITIONAL $8500 I HAVE PUT INTO IT. THIS IS HOW MERCEDES BENZ TAKES CARE OF BUSINESS? SOMETHING HAS DRASTICALLY CHANGED. MY DAD HAS HAD 2 MERCEDES OVER THE LAST 30 YEARS...THEY RAN PERFECTLY UNTIL HE SOLD THEM. HE JUST BOUGHT A BRAND NEW S-SERIES (2012) AND IT HAS ALREADY BEEN IN THE SHOP NUMEROUS TIMES. THE CARS ARE MADE CHEAP AND EVERYTHING IN THE INTERIOR IS PLASTIC, NOT WOOD AS IT SHOULD BE. MERCEDES, YOU SHOULD BE ASHAMED OF HOW FAR YOU HAVE LET YOUR STANDARDS FALL, IT IS A DISGRACE. *TR

MERCEDES C230 KOMPRESSOR. THE BOLT THAT HOLDS THE ALTERNATOR BELT HAS BROKE 3 TIMES! WHEN THE BELT SLIPPED IT AFFECTED THE POWER STEERING AND I WAS UNABLE TO STEER! VERY SCARY, LUCKILY I WAS DRIVING UNDER 25 MPH AT THE TIME. THERE MUST BE A DEFAULT IN THE DESIGN FOR THIS TO KEEP HAPPENING! *TR

RE: C 240 MERCEDES 2004. THE CAR WILL SUDDENLY CUT OFF WHILE DRIVING. THIS HAS HAPPENED ON LONG DRIVES ON THE INTERSTATE, SHORT DRIVES ON THE INTERSTATE, AND STREET DRIVING. THE MECHANIC CANNOT FIND ANY CODES ASSOCIATED WITH THIS DEFECT. WE HAD THE CRANK SENSOR CHANGED BECAUSE THE MECHANIC THOUGHT THAT A WORN CRANK SENSOR MIGHT BE THE CAUSE. IT WAS NOT. TWO DAYS LATER THE CAR 'S ENGINE SHUT DOWN AGAIN. *TR

THIS IS A 2004 MERCEDES C230. CHECK ENGINE LIGHT WENT ON. I WENT TO DEALER WITHIN 15 MILES OF WARNING LIGHT COMING ON. I WAS TOLD THAT THERE WAS AN OIL LEAK AND THAT IT HAD DRIPPED OVER THE WIRING HARNESS. IT WOULD COST $3,500 TO REPAIR. I HAVE NEVER MISSED A MAINTENANCE ON THIS CAR. THEY SAID THE THIS HAPPENS BECAUSE OF WHERE THE O2 SENSOR IS LOCATED. THIS IS A DEFECT AND DESIGN FLOW CREATED BY MB. THEY SHOULD DO A RECALL TO PROTECT THE WIRING HARNESS

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

THIS IS A 2004 MERCEDES C230. CHECK ENGINE LIGHT WENT ON. I WENT TO DEALER WITHIN 5 MILES OF WARNING LIGHT COMING ON. I WAS TOLD THAT THERE WAS AN OIL LEAK AND THAT IT HAD DRIPPED OVER SEVERAL COMPONENTS AND THE WIRING HARNESS. I WOULD COST $3,500 TO REPAIR BUT THEY ABSORBED THE LABOR COST AND IT SHOULD COST ABOUT $2,000. I HAVE NEVER MISSED A MAINTENANCE ON THIS CAR. THEY SAID THE THIS HAPPENS BECAUSE OF WHERE THE O2 SENSOR THAT LEAKED IS. IT SEEMS ODD TO HAVE MINOR ISSUE CAUSE SUCH ENORMOUS DAMAGE. *TR
