TL* THE CONTACT OWNS A 2006 MERCEDES-BENZ SLK350. THE CONTACT STATED THAT THE VEHICLE EXPERIENCED A LACK OF ENGINE POWER AFTER ACCELERATING FROM A COMPLETE STOP. THE CONTACT STATED THAT THE VEHICLE HAD TO BE MANUALLY RESTARTED TO BE OPERATED NORMALLY. THE FAILURE OCCURRED WITHOUT WARNING. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE VALVE BODY WAS DEFECTIVE AND NEEDED TO BE REPLACED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 63,038.

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.

TL* THE CONTACT OWNS A 2006 MERCEDES BENZ SLK350. WHILE DRIVING AT 45 MPH, THE VEHICLE BEGAN TO DECELERATE INDEPENDENTLY. THE CONTACT STATED THAT THE VEHICLE WAS TURNED OFF AND RESTARTED WHEN SUDDENLY THE VEHICLE JUMPED INTO FIRST GEAR. THE CONTACT ALSO STATED THAT THE VEHICLE WOULD NOT SHIFT FROM THE FIRST GEAR. THE VEHICLE WAS RESTARTED AGAIN AND THE VEHICLE FUNCTIONED AS NORMAL. THE VEHICLE WAS TAKEN TO THE DEALER WHERE IT WAS DIAGNOSED THAT THE TRANSMISSION VEHICLE SPEED SENSOR FAILED AND THE TRANSMISSION CONTROL MODULE NEEDED TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 66,000.

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.

TL* THE CONTACT OWNS A 2006 MERCEDES BENZ SLK 280. THE CONTACT STATED THAT THE ENGINE RPM READING INCREASED AS THE ENGINE ROARED AND THE GEAR SHIFTER DISENGAGED INDEPENDENTLY. AS A RESULT, THE VEHICLE LOST ACCELERATION POWER. THE FAILURE WAS EXPERIENCED SEVERAL TIMES WHILE THE CONTACT DROVE AT VARIOUS SPEEDS. THE VEHICLE WAS TAKEN TO THE DEALER WHERE A DIAGNOSTIC WAS PERFORMED. THE FAILURE WAS LOCATED AT THE TRANSMISSION CONTROL PLATE. THE VEHICLE WAS REPAIRED AND THE TRANSMISSION CONTROL PLATE WAS REPLACED. THE VIN WAS NOT AVAILABLE. THE APPROXIMATE FAILURE MILEAGE WAS 59,000 AND THE CURRENT MILEAGE WAS 60,100.

THE CAR WENT INTO "LIMP HOME MODE" TWICE WHILE I WAS DRIVING DURING THE PAST FEW MONTHS. THE SECOND TIME IT HAPPENED ON THE HIGH WAY: GEARSHIFTS NO LONGER POSSIBLE AND THE CAR WAS GOING ABOUT 20 MILES PER HOUR. IT WAS PRODUCING VERY LOUD NOISE AND SCARY. A COLLISION COULD HAVE HAPPENED. AFTER SOME RESEARCH ONLINE AND TALKING TO MY MECHANIC, MERCEDES-BENZ'S 722.9 TRANSMISSION IS A KNOWN AND WIDESPREAD PROBLEM. MY MECHANIC HAD TO REPLACE THE TRANSMISSION VALVE BODY. ACCORDING TO MY RESEARCH ONLINE AND WHAT MY MECHANIC TOLD ME, MOST MERCEDES BETWEEN 2006 AND 2010 HAD THIS PROBLEM. THERE SHOULD HAVE BEEN A RECALL FOR THIS. *TR

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

THE TRANSMISSION LOCKS UP INTERMITTENTLY & WON'T UP SHIFT. THE TRANSMISSION WILL SUDDENLY GO INTO LOW GEAR WHILE DRIVING ON THE HIGHWAY. THIS IS A VERY DANGEROUS SITUATION AND MERCEDES-BENZ SAYS THEY DON'T HAVE A PROBLEM WITH THE TRANSMISSION. A INDEPENDENT MERCEDES-BENZ REPAIR SHOP SAID THIS IS A COMMON PROBLEM THAT ALL THE 7 SPEED TRANSMISSIONS ARE DOING. MERCEDES-BENZ WILL NOT PAY FOR THE REPAIR AND THEY SAY THEY WON'T SELL THE INTERNAL TRANSMISSION PARTS TO INDEPENDENT SERVICE PROVIDERS. THEY FORCE THE CUSTOMER TO GO TO THEIR AUTHORIZED DEALER AND PAY FOR THE REPAIR. THIS IS WRONG! *JS

WHILE PERFORMING U-TURN IN LIGHT TRAFFIC, TRANSMISSION WOULD NOT SHIFT INTO REVERSE, THEN WOULD ALSO NOT SHIFT INTO DRIVE, LEAVING VEHICLE IMMOBILIZED IN THE MIDDLE OF TRAFFIC. *TT

TL*THE CONTACT OWNS A 2006 MERCEDES BENZ SLK280. WHILE DRIVING 70 MPH, THE VEHICLE SHIFTED GEARS WITHOUT WARNING. THE DEALER STATED THAT THE VALVE BODY NEEDED TO BE REPLACED AT THE COST OF $2,562. THE MANUFACTURER WOULD NOT ASSIST AND THE VEHICLE HAS NOT BEEN REPAIRED. THE VIN WAS UNKNOWN. THE FAILURE AND CURRENT MILEAGES WERE 80,000.
