ENGINE AND ENGINE COOLING
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.

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!

ENGINE AND ENGINE COOLING
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

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
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.
