2006 MERCEDES-BENZ C230 Complaints

SUDDENLY DURING NORMAL DRIVING CONDITIONS, WHEN TRYING TO ACCELERATE THE CAR IS VERY SLUGGISH AND THE RPM ARE VERY HIGH. THIS HAPPENS WITHOUT WARNING INCREASING THE POTENTIAL FOR A CRASH. THE PROBLEM IS NORMALLY RECTIFIED TEMPORARILY BY RESTARTING THE VEHICLE. *TR

TOOK OUR DAUGHTER'S 2006, C230 MERCEDES BENZ TO OUR MERCEDES CERTIFIED MECHANIC TO REPAIR A SLUGGISH PROBLEM THAT CAUSED THE CHECK ENGINE LIGHT TO COME ON.. I WAS INFORMED THAT A PART IN THE ENGINE CALLED THE BALANCER WAS GOING BAD... THE COST IS AN APPROX $5000.00. AND THAT WE WOULD HAVE TO TAKE IT TO THE LOCAL MERCEDES DEALERSHIP TO DO THE REPAIR. THE PART INSTALLED IN THE 2006 AND 2007 MODELS WAS MADE OF A TOO SOFT A METAL, SO ITS A DEFECTIVE PART TO START WITH! THIS PART APPARENTLY CAUSES THE ENGINE TO LOSE POWER WHILE DRIVING... BENZ HAS NOT ISSUED A RECALL ON THIS PART. *TR

2006 MERCEDES C230, LOSS OF POWER AND ACCELERATION. FIRST TIME IT HAPPENED WHEN THE MILEAGE WAS 62K. I WAS DRIVING ON SHENNANDOAH VALLEY THEN SUDDENLY THE ACCELERATION AND ENGINE POWER KEEP DECREASING THOUGH MY FOOT WAS COMPLETELY PRESSING ON GAS PEDAL. I DECIDED TO FULL-OVER TO COOL DOWN THE ENGINE. AFTER RE-STARTING IT, THE PROBLEM WENT AWAY FOR AWHILE AND BACK TO NORMAL DRIVING CONDITION. THEN IT HAPPENED AGAIN WHEN MY CAR HAD 65K MILES, I EXPERIENCED THE SAME PROBLEM BUT THIS TIME FROM A COMPLETE STOP FROM TRAFFIC LIGHT, WHEN I TRIED TO ACCELERATES.. THE CAR WAS NO ACCELERATION AT ALL THOUGH THE PEDAL WAS COMPLETELY TO THE METAL. THIS WILL BE A VERY BAD SITUATION WHEN ALL OF A SUDDEN IT WILL NOT ACCELERATE TO NORMAL RUNNING CONDITION, WHEN I NEEDED TO ENTER THE HIGHWAY TO MERGE TO A FAST MOVING TRAFFIC. *TR

TOOK THE VEHICLE TO THE DEALER WHEN THE CHECK ENGINE LIGHT CAME ON. CAR WAS DIAGNOSED WITH A BAD BALANCE SHAFT THAT NEEDED TO BE REPLACED. APPARENTLY THIS HAS BEEN A PROBLEM WITH THIS ENGINE ON NUMEROUS MODELS OF MERCEDES AS CLASS ACTION LAWSUITS HAVE BEEN FILED IN NUMEROUS STATES. *JS

ON OR ABOUT MAY 17, 2011 MY 2006 C230 AT THE TIME WITH 83,312, YOU DRIVE NORMALLY, MAKE A STOP ON A TRAFFIC LIGHT FOR EXAMPLE, WHEN IT'S TIME TO GO, YOU RELEASE THE BRAKE, ACCELERATE, AND NOTHING HAPPENS EXCEPT FOR RPMS REVVING UP. THE GEAR SHIFTER IS IN "D" DRIVE, GAUGE BETWEEN THE ODOMETER/TACHOMETER SHOWS "D" DRIVE AS WELL, HOWEVER THE CAR ACTS AS IF IT WAS IN NEUTRAL!!! SHIFTING INTO NEUTRAL, REVERSE, OR PARK, OR BACK INTO DRIVE - DOESN'T HELP! IT'S LIKE A TRANSMISSION IS STUCK IN NEUTRAL!!! ALSO, SHIFTING INTO D+/- TO ENGAGE MANUAL SHIFTING DOESN'T WORK! AND AS FAR AS YOU KEEP MOVING THE SHIFTER INTO REVERSE, NEUTRAL, MANUAL SHIFT, DRIVE - THE CAR ELECTRONIC GEAR DISPLAY ON THE DASHBOARD STILL SHOWS THAT THE CAR IS IN "D" DRIVE REGARDLESS OF WHAT POSITION YOU MOVE THE SHIFTER; AND THE CAR BEHAVES AS IF IT WAS IN NEUTRAL ALL THIS TIME (YOU ACCELERATE, RPMS GOES UP, REMOVE THE FOOT FROM THE PEDAL - ENGINE IDLES). THE ONLY WAY TO MAKE THE TRANSMISSION WORK AGAIN IS TO SHIFT IT INTO PARK "P", AND THEN TURN OFF THE ENGINE, AND THEN TURN THE ENGINE BACK ON, AND THEN TRANSMISSION WORKS WELL AGAIN FOR TENS OR HUNDREDS OF MILES BEFORE IT GETS "NEUTRALIZED" PARALYZED AGAIN. THIS ALSO HAPPENED TO ME WHILE DRIVING DOWN THE I-5 IN CALIFORNIA AROUND 70 MPH'S AND I HAD TO PULL TO THE SIDE OF THE ROAD AND TURN THE CAR OFF AND BACK ON, IN ORDER FOR IT TO START WORKING NORMAL. THAT IS DANGEROUS, WHAT IF I WOULDN'T HAVE BEEN ABLE TO STOP ON THE SIDE OF THE ROAD IT WOULD HAVE CAUSED AN ACCIDENT. *JB

TL* THE CONTACT OWNS A 2006 MERCEDES BENZ C230. WHILE DRIVING 25 MPH, THE CONTACT ATTEMPTED TO ACCELERATE AND NOTICED THAT THE VEHICLE HAD SHIFTED INTO NEUTRAL EVEN THOUGH THE GEAR INDICATOR DISPLAYED THAT THE VEHICLE WAS IN DRIVE. THE VEHICLE WAS TAKEN TO THE DEALER, WHERE THE CONTACT WAS INFORMED THAT A SENSOR WHICH CONTROLLED THE TRANSMISSION SHIFT SEQUENCES NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 61,000. UPDATED 05/02/12 *BF THE CONSUMER STATED THE VEHICLE WAS REPAIRED AT A COST OF $1200.00. UPDATED 05/04/12

MY 2006 MERCEDES C230 HAS A DEFECTIVE BALANCE SHAFT. I DID SOME RESEARCH AND MULTIPLE PEOPLE ARE HAVING THE SAME PROBLEM. THERE IS A CLASS ACTION SUIT IN THE WORKS. I BELIEVE THIS IS A DEFECTIVE PART THAT NEEDS TO BE RECALLED. *TR

HAVING PROBLEM WITH THE GEAR SHIFTING, BELIEVE THIS IS CAUSED BY THE SHAFT BALANCER, ETC. THE CAR GRABS AND JERKS FROM TIME TO TIME MAKING ME UNSURE OF THE SAFETY OF MY CAR. MY CAR ONLY HAS 84,000 MILES ON IT. THE CAR IS LIKE NEW, BUT AS I READ THE CLASS ACT AGAINST MERCEDES I NOTICED THAT MY CAR HAS SEVERAL OF THE SAME ISSUES AS OTHERS LISTED IN THE COMPLAINT. THE INTERIOR AND EXTERIOR OF MY CAR IS IN EXCELLENT CONDITION, AND I CAN'T BELIEVE THAT THE MERCEDES COMPANY WOULD ALLOW AN ERROR LIKE THIS TO CONTINUE. I WOULD LIKE FOR THIS TO BE CORRECTED BY MERCEDES OR TO BE PLACED ON THE CLASS ACT SUIT AS WELL. *TR

CHECK ENGINE LIGHT KEEPS COMING ON SAYING SOMETHING IN ENGINE IS BAD WITH A PRICE TAG OF OVER 6000.00 TO FIX. *TT

PERIODICALLY THE CAR WOULD LOSE ACCELERATION AND RPMS WOULD BE HIGH AND THE VEHICLE WOULD JERK WHEN I TRIED CHANGING GEARS. AS I CHANGE GEARS FROM PARK, REVERSE OR DRIVE, THE GEAR SHIFT JERKS AND I AM UNABLE TO ACCELERATE PAST 20 MPH NO MATTER HOW MUCH PRESSURE I PLACE ON THE GAS. : EXTREME LOSS OF ACCELERATION UP HILL AND THE STEPTRONIC (+/- SHIFTING) DID NOT WORK... (I COULD ONLY GO 35MPH WHEN EVERY ONE ELSE WAS GOING 70MPH UP HILL) WHEN I TRAVELED ON A FLAT SURFACE WITH NO INCLINATION MY CAR WORKED FINE, I THEN DECIDED TO PUT IT ON NEUTRAL WHILE TRAVELING AT 65MPH...WHEN I PUT IT BACK IN DRIVE IT DID NOT PICK UP THE GEARS IT JUST CONTINUED AS IF IT WAS IN NEAUTRAL. I HAD TO PULL OVER AND SHIFT IT INTO PARK...AS I SHIFTED FORM "D" TO NEUTRAL IT SHIFTED FINE, BUT THEN FROM NEUTRAL TO "R" THE CAR JERKED...FROM REVERSE TO "P" IT JERKED AGAIN AND SHIFTED HARD. I THEN SHIFTED AGAIN TO REVERSE, NEUTRAL, AND DRIVE THUS THE CAR JERKED AND DID A HARD SHIFT WITH KNOCKING NOISE AND WOULD NOT DRIVE. I SHIFTED TO NEUTRAL AGAIN AND SHUT THE CAR OFF. WHEN I TURNED IT BACK ON IT SHIFTED SMOOTH AND I DROVE OFF WITHOUT ANY PROBLEM. TOOK IT TO A REPAIR SHOP AND RECEIVED P0717/P0718 FAULT CODES AND SOMETHING ABOUT THE VALVE BODY. I WAS ALSO TOLD THAT IT WAS AN TRANSMISSION INTERNAL SPEED SENSOR ISSUE. THERE IS SOMETHING FAULTY WITH THE DESIGN AND OPERATION OF THIS MODEL YEAR TRANSMISSION AND LOSING POWER AND BEING ABLE TO ONLY GO 35 MPH NO MATTER HOW MUCH YOU PRESS THE GAS ON THE INTERSTATE OR HEAVY FAST MOVING TRAFFIC IS EXTREMELY DANGEROUS. MERCEDES BENZ IS AWARE OF THIS PROBLEM AS MANY OWNERS HAVE COMPLAINED BUT THEY WILL NOT INSTITUTE A RECALL. *TT
