2005 Mercedes-Benz SLK-Class Engine Problems

improper heat treatment of the balance shaft spocket causing the balance shaft to worn out resulting in advance timing of the CAM. Mercedes acknowledges it's an known issue but don't cover cost of fixing it. Once ecu detected timing is off, it will stop the transmission from accelerating without any warning. Happened to me on a highway, good thing the car still have some momentum and was able to pull to the shoulder while others cars are coming from behind.

TOOK MY CAR IN, IT WOULD NOT GO INTO REVERSE, THEN THE ENGINE WAS WINDING OUT REALLY HI ON THE TACHOMETER, MERCEDES SAID IT WAS THE VALVE BODY MODULE IN TRANSMISSION, OK- THEN THEY TOLD ME MY ENGINE BALANCE SHAFT WAS NOT WORKING AND THE LABOR WAS 5628.00 THEY HAVE NOT YET QUOTED ME A PRICE ON THE PARTS FOR EITHER ISSUE. SAID THE ENGINE WILL JUST SEIZE UP WHEN DRIVING, I LOOKED THIS UP ON INTERNET AND THERE SEEMS TO BE A CLASS ACTION SUIT GOING ON WITH THIS BALANCE SHAFT ISSUE.IS THIS A SAFETY ISSUE THEY OVERLOOKED POSSIBLY ? MILES AS LOW AS 62K HAVING SAME ISSUE. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6). *TR

ON FEBRUARY 18/2011 AND WHILE DRIVING MY 2005 SLK 350 START SHAKING AND THE LIGHT "CHECK ENGINE" TURNED ON. I TOOK THE CAR TO THE DEALER AND IT WAS RETURNED A COUPLE OF DAYS AFTER AND I WAS TOLD THAT THE CAR IS OK. THERE IS/ WAS NO PROBLEM WITH THE ENGINE AND THE LIGHT WAS RESET TO NORMAL. AFTER A COUPLE OF DAYS THE CAR START SHAKING AGAIN AND THE LIGHT "CHECK ENGINE" WAS ON AGAIN. THE CAR WAS TAKING TO MERCEDES DEALER AND SAME ANSWER THE CAR IS OK OR WE HAVE NOT FOUND ANY PROBLEM WITH THE ENGINE AND THE LIGHT WAS RESET BACK TO NORMAL...WELL, IT HAD HAPPENED TWO MORE TIMES SINCE THEN. TODAY IS MARCH, 31ST AND THE LIGHT IS ON AGAIN AND I AM DRIVING A CAR THAT KEEPS SHAKING AND I FEEL VERY MUCH UNSAFE. I AM DRIVING A VERY EXPENSIVE CAR AND I CAN'T ACCEPT AND I WILL NOT ACCEPT THE IDEA THAT I SHOULD BE DRIVING A CAR THAT DOES NOT MAKE ME FEEL SAFE. THE SERVICE AT THE MERCEDES DEALERSHIP HAS BEEN GOOD. THEY HAVE TAKING MY CAR FROM MY OFFICE AND BROUGHT ME A LOANER CAR AND THEY ARE KIND TO ME AND I DO APPRECIATE THAT A LOT; BUT, AT THE SAME TIME, I FEEL THAT IF THE TECHNICIAN CAN'T NOT FIND THE PROBLEM, SOMETHING IS VERY WRONG AND WHY MY SAFETY SHOULD BE EXPOSE. WHY AM I DRIVING AN EXPENSIVE CAR THAT IT IS NOT RELIABLE AND IT IS GIVING ME ADDITIONAL STRESS THAT I DON'T NEED. MY QUESTION IS: IS MERCEDES INDEED A RELIABLE CAR? WHY AM I NOT HAVING A PEACE OF MIND WHILE DRIVING? WHAT KIND OF DANGER AM I EXPOSE TO WHILE DRIVING A CAR THAT HAS A "CHECK ENGINE" LIGHT ON? WHY AM I DRIVING A CAR THAT IS SHAKING? HOW MUCH PATIENCE SHOULD I HAVE? WHY DO I NEED TO PAY ANYTHING EXTRA FOR A CAR THAT THEIR OWN MANUFACTURER DOESN'T KNOW WHAT THE PROBLEM IS? WHAT IS MERCEDES DOING FOR THE SAFETY OF THEIR CLIENTS? MERCEDES HAD CALLED ME TODAY AND THEY WILL PICK UP MY CAR TOMORROW AND "SPENT" MORE TIME TRYING TO FIGURE OUT WHAT THE PROBLEM IS.I THOUGHT THAT'S WHAT THEY WERE DOING THIS LAST 4 TIMES THE CAR WHERE TAKING TO THE SHOP. WHAT ARE MY RIGHTS. *TR

DT: THE CONTACT STATED THE CAR WAS BURNING AN EXCESSIVE AMOUNT OF OIL. THE VEHICLE USED TWO QUARTS OF OIL AT ONLY 5, 500 MILES. THE DEALERSHIP TEST DROVE THE VEHICLE AND FOUND THAT THE VALVES WERE NOT SEATED. ALSO, AT TIMES WHILE PRESSING THE ACCELERATOR PEDAL THE VEHICLE WILL NOT MOVE IT WILL ONLY REV THE ENGINE. THE DEALERSHIP WAS CONTACTED, THEY TOLD HER THE NEXT TIME THIS OCCURRED TO SHUT THE ENGINE BY PUTTING THE CAR IN PARK AND TURNING THE KEY TO THE OFF POSITION. THERE HAVE BEEN NO REPAIRS MADE TO THE TRANSMISSION BECAUSE THE DEALERSHIP DID NOT HAVE ENOUGH INFORMATION TO MAKE ANY CORRECTIONS. *AK UPDATED 2/24/2006 - THE VEHICLE WAS TOWED TOT HE DEALER ON 1/26/2006 AND TOLD THAT THERE WAS A PROBLEM WITH THE TRANSMISSION.
