2011 BMW 550I Xdrive power train problems

“Vehicle displays Transmission Malfunction & DSC and xDrive malfunction, this vehicle is available upon request for inspection. Currently been to two dealerships and all I got from the first dealership is to replace transmission at 59k mile. I purchased a used transmission same problem exist in the replacement transmission. As I was driving on highway, the transmission began displaying message above and caused the vehicle suddenly slow down without warning lights causing me to avoid an accident by pulling over to avoid being rear ended. The problem has been reproduced by dealer: tech and service advisors manager( authorized to drive) and he charge me for a tow even after I mention to him I have AAA if he needs it. Service manager stated that it may need the mechatronics unit which $4k for part but they’re unsure because they didn’t take it apart but it’s a known issue. They mention that it’s a known problem for the TCM (mechatronic valve throttle body control module to go bad). Manufacturer has not inspected vehicle. So currently it’s at BMW of Owings Mills get a second opinion.”

“I started my car to drive to an appointment and noticed that the car was jerking/bucking as I pulled out of my driveway onto the main road. I was unable to accelerate appropriately for oncoming traffic behind me because the car was jerking violently and it was a bit scary since this had not happened before. This continued for several days, primarily when I would attempt to drive the car in the morning. On one occasion the drive train malfunction light illuminated as I was making my way to an appointment at the Veterans Administration and I had to gingerly turn the car around and head back home. Someone could have ran into me because the car didn't have much power. What followed next was the inability to get my car to move when it was placed in reverse. I took the car to the dealership and was told that the car's transmission needs to be replaced ($11,000) because the car is trying to drive in reverse and first gear at the same time. What?!! In over 20 years of servicing BMW's, they have never seen a situation like this. I don't believe I should bear the cost for this when I bought a pretty expensive car in good faith, which has only 80,000 miles.”

“DRIVETRAIN MALFUNCTION COMES ON DASH, DUE TO TIMING CHAIN BEING OUT OF "TIME" MEANING THAT THE CRANSHAFT AND CHAIN HAS MOVE OUT OF PLACE, THIS REPAIR IS ESTIMATED TO COST ABOUT 10K, OTHER VEHICLES OF THE THIS TYPE ARE ALSO INCLUDED, THE RECALL FROM BMW IS CALL THE "N63 CUSTOMER SERVICE PACKET", N63 IS THE KIND OF ENGINE THAT THIS CAR AND OTHER IN SIMILAR SERIES AND YEARS ARE KNOWN AND INNEVIDATABLE TO PREVENT SINCE ITS A MANUFACTURER MISTAKE. I PERSONALLY LOST OUT ON A LOT OF MONEY DUE TO THE PROBLEM THAT LANDED IN MY HANDS.”
