ENGINE
August 2024, while driving on a 4 lane highway at 65 mph, a warning appeared on gauge cluster saying that Electronic Stability Control and Traction Control inoperable. This caused the car to reduce power, requiring me to quickly pull over. The car continued running but I was limited on mph and gear selection (aka Limp Mode). I turned the car off, allowing the systems to reset. After driving approximately 1 miles, the same warnings appeared. Fortunately, I was within a mile from home at the time so I was able to "Limp" the car home. The next day, I checked the car again by driving in my neighborhood with the result. I had the car transported on roll back to Express Oil and Tire in Barboursville, WV as my "local" MB dealer is an hour away. They checked the car and the Engine Control Module was defective and needed replacement. The cost of the service including new MB parts and programming would be $2,495. I tried for 2 months to secure funding to fix the car to no avail. I had the car towed on roll back again but back to my house. The car has sat since then.

ENGINE
THE VEHICLE HAS ONLY 50K MILES. I AM THE ONLY OWNER AND I PURCHASED THE VEHICLE IN 2010 (NEW) WITH ONLY 9 MILES. I HAVE COMPLETED ALL REQUIRED SERVICES TO DATE. IN MAY I HAD THE AB SERVICE COMPLETE AND THE CHECK ENGINE LIGHT WAS ON. I WAS TOLD IT WAS LIKELY DUE TO THE NEED OF HAVING THE SPARK PLUGS CHANGE BASED ON TIME NOT MILEAGE. NOW I AM BEING TOLD THE OUTCOME OF THE CHECK ENGINE LIGHT ON IS DUE TO A MISFIRE CODE FOR CYLINDER ONE, FAILED SDS COMPRESSION TEST. CYLINDER ONE FAILED CYLINDER LEAK DOWN TEST AT 80%. EXHAUST VALVE SEATS FAILING CAUSING EXHAUST VALVES NOT TO FULLY CLOSE. WE ARE UNABLE TO REPAIR THE VALVE SEAT ON CYLINDER HEAD AND IT IS NECESSARY TO REPLACE PASSENGER SIDE CYLINDER HEAD. ONLY CAMSHAFTS AND CAM ADJUSTERS CAN BE TRANSFERRED. NEW HEAD WILL COME WITH NEW VALVES. THERE ARE REPEATED REPORTS FROM OTHER OWNERS WITH THIS SAME ISSUE-RESULTING IN ENORMOUS REPAIR COST. THIS IS A DEFECT AND MERCEDES-BENZ NEED TO CONSUME THE COST, ESPECIALLY SINCE THE VEHICLE HAS LESS THAN $50K MILES.

ENGINE AND ENGINE COOLING:EXHAUST SYSTEM
THIS COMPLAINT IS FOR A 2010 BMW 535I XDRIVE. I WENT INTO THE GARAGE TO START MY CAR THIS MORNING WEDNESDAY, 10/28/09 AND THE CHECK ENGINE LIGHT CAME ON AND THE CAR STARTED SHAKING. I MOVED THE CAR OUT OF THE GARAGE AND SHUT OFF THE ENGINE TO SEE IF IT WOULD RESET, I STARTED THE CAR UP AGAIN AND THE CHECK ENGINE LIGHT WAS STILL ON AND THE CAR CONTINUED SHAKING, I DROVE THE CAR ABOUT 50FT TO SEE IF IT WOULD STOP SHAKING AND LIGHT WOULD GO OUT BUT IT DID NOT. I DROVE THE CAR BACK INTO THE GARAGE AND WAITED ABOUT A 1/2 HOUR TO TRY IT AGAIN IT WAS THE SAME PROBLEM. I CONTACTED THE SERVICE DEPARTMENT WHOM ADVISED ME TO CONTACT ROADSIDE ASSISTANCE TO HAVE THE CAR TOWED IN BECAUSE IT SHOULD NOT BE DRIVEN. I HAD THE CAR TOWED TO OPEN ROAD BMW WHERE I HAD PURCHASED THE CAR FROM TWO (2) MONTHS AGO. I SPOKE WITH THE SERVICE ADVISOR AND ASKED HAD ANYONE ELSE EXPERIENCED THIS PROBLEM HE SAID YES ON THE 2009 AND 2010 MODELS IT SEEMS TO BE THE FUEL PUMP. THERE SEEMS TO HAVE BEEN A PROBLEM WITH THEM, BUT ONCE THEY HAVE BEEN REPLACED THAT SEEMS TO HAVE FIXED THE PROBLEM. I AM WAITING TO HEAR BACK FROM THE SERVICE DEPARTMENT.
