2006 Mercedes-Benz SLK350 Owner Complaints

I was traveling on I20 going about 60mph. Car suddenly started fish tailing and thought I had a flat tire. Pulled over, no flats but back driver's side wheel was crooked. Had car towed to service center. Back frame is extremely rusted. My whole wheel could have come off which would have been extremely serious. My car only has 46000 miles and garage kept. No warning signs. I don't drive in wintry conditions. My car has only been inspected by the service mechanic and myself.

WHILE DRIVING VEHICLE POWER CAN BE LOST & VEHICLE CAN BE STUCK IN 1ST GEAR OR NO GEAR AT ALL CAUSING BLOCKAGE TO TRAFFIC AND POSSIBLY CAUSING AN ACCIDENT. ONCE YOU TURN CAR OFF IT APPEARS THE CAR RESETS ITSELF AS IF NOTHING EVER HAPPEN. WHEN REPORTED TO DEALERSHIP IT WAS STATED NO CODES POP UP SO I MUST BE HITTING THE SHIFT. NOT KNOWING ANY BETTER & NOT BEING A MECHANIC, WHO AM I TO CONTINUE TO QUESTION THE MERCEDES DEALERSHIP? NO CODE NO ACTION. (1ST REPORTED WITH 8446 MILEAGE NEVER SHOWED A CODE). AT 63,000 MILES THE ENGINE LIGHT FINALLY COMES ON INDICATING A PROBLEM. 63038 FOUND CODE IN SYSTEM FOR SPEED SENSOR NOT READING CORRECTLY. TEST DROVE CAR & STUCK IN LIMP HOME. THE ODD THING IS THE CODE KICKED IN AT 61400 MILES & THE LIGHT CAME ON 2000 MILES LATER. THE EXTENDED WARRANTY COMPANY REFUSED TO FIX MY CAR UNDER THE WARRANTY I PURCHASED DUE THE "DATA FREEZE' SHOWING PROBLEM EXISTED PRIOR TO ME PURCHASING THAT WARRANTY BUT I WAS UNAWARE OF THAT SINCE THE ENGINE LIGHT DIDN'T COME ON AT 61400. AT ANY RATE IT APPEARS TO BE A LOT OF COMPLAINTS WITH THESE VALUE BODIES WITH LOW MILEAGE. PEOPLE BUY MERCEDES THINKING IT WILL BE A WHILE BEFORE THE START HAVING THESE PROBLEMS YET COMPLAINTS ON THIS VALUE BODY IS ALL OVER THE INTERNET. ... FOUND BELOW ON INTERNT. I PAID $1800 FOR THIS REPAIR. OCT 29, 2012 - PLAINTIFFS BROUGHT A CLASS ACTION LAWSUIT AGAINST MERCEDES BENZ ON BEHALF ... AN ENTIRE VALVE BODY REPLACED THAT ONLY THE MERCEDES DEALER CAN REPAIR. .... 61,000 MILES, OUT OF WARRANTY, AND JUST NOW THEY SAID, THEY WILL NOT COVER AND NOW THE MB 722.9 VALVE BODY - COBRA TRANSMISSION ...

3 ISSUES--CAMSHAFT SELENOID; DEFECTIVE GEAR IN THE BALANCE SHAFTS OF THE ENGINE; TRANSMISSION VALVE BODY DEFECT. ALL THREE OF THESE ISSUES HAVE BEEN DOCUMENTED BY MERCEDES INTERNAL DOCUMENTS AND THERE IS A CLASS ACTION SUIT ON GOING FOR THE DEFECTIVE GEAR IN THE BALANCE SHAFTS OF THE ENGINE RIGHT NOW. THESE ARE CRITICAL ISSUES AS THE CAR CAN LOSE POWER. WITH REGARD TO THE BALANCE SHAFT ISSUES, METAL FROM THE SHAFT DETERIORATES AND THAT INFILTRATES THE OTHER ENGINE PARTS CAUSING THE ENGINE TO PREMATURELY FAIL. ALMOST ALL OF THE REPORTS ON THIS ISSUE ARE FOR SLK350'S WITH LESS THAN 80,000 MILES.

SEVERE JERK AS VEHICLE DECELERATED AROUND 10-12 MPH. TOOK VEHICLE TO DEALERSHIP AND TEST DROVE WITH TECHNICIAN WHO VERIFIED THE PROBLEM. THERE WERE NO WARNING LIGHTS OR CODES FOUND. I WAS NOTIFIED BY THE DEALERSHIP THAT THERE WAS A SNAP RING FAILURE WITHIN THE GEAR BOX. INVOICE INDICATES "RETAINING CLIP FAILURE INSIDE TRANSMISSION, VERIFIED SEVERE 3-2 DOWN SHIFT, SHORT TEST NO CODES.CHECK OF ADAPTATION DATA FOUND 3-2 DOWN SHIFT AT NEGATIVE LIMIT. REMOVED TRANSMISSION AND INSPECTED, FOUND B1 RETAINING CLIP FAILURE. REPLACE B1 AND B3 TENSIONING SPRINGS AND RETAINING CLIPS". MB CORPORATE WAS NOTIFIED WITH NO ASSISTANCE. I WAS APPALLED AT THE STATEMENTS MADE BY CUSTOMER COMPLAINT MANAGER WHO STATED "THE CAR HASN'T BEEN IN FOR SERVICE SINCE 2009", I RESPONDED BY SAYING THE VEHICLE WASN'T DUE FOR SERVICE UNTIL 26K MILES, MAINTENANCE IS DETERMINED BY MILEAGE, NOT YEARS, IF I'M CORRECT. SHE ALSO INDICATED THAT "RECALLS WERE ALWAYS VIN SPECIFIC" AND MY CAR WASN'T ONE OF THEM. I BELIEVE THERE'S A PROBLEM WITH THE TRANSMISSION THAT'S BEING CONCEALED BECAUSE MOST OF THE FAILURES ARE OCCURRING AT LOW MILES WHILE THE VEHICLES ARE STILL UNDER WARRANTY. MY VEHICLE WAS OUT OF WARRANTY DUE TO AGE BUT HADN'T TURNED 26K MILES YET. THE DIAGNOSIS WAS CLASSIFIED AS A FAILURE WHICH SHOULD HAVE BEEN TAKEN CARE OF BY THE MANUFACTURER. THERE NEEDS TO BE AN INVESTIGATION INTO HOW MANY REPAIRS HAVE BEEN MADE ON THE 7G TRANSMISSION. THERE IS A PROBLEM. *TR
