The car randomly misfires and goes into limp mode with a flashing check engine light. This has occurred on roadways and the vehicle loses all engine power. My engine code, 272920 30 183997272.920, falls into a known range of balance shaft gear problems with this motor. There was previously a settlement by the manufacturer to repair the motor but I was unaware of this settlement before purchasing this vehicle as there was no official recall. I am being told the repair requires pulling the motor out which is quite a high cost. The problem has been confirmed by an independent mechanic inspecting the camshaft timing. There were no other indicators of this failure before the check engine light came on and flashed.

Just like other reports here - electrical malfunction. 50k miles. Took to mb dealer for rough idle at cold start up and low speeds; louder than normal idle at start and in reverse. No check engine light, no error or problem indicated in dash at all. Same diagnosis - dealer reported cam solenoids leaking engine oil into the wiring harness shorting harness components (o2 sensors etc.), high $$$ $3600-$4000 repair. Issue should be resolved and paid for by mb since this is known defect that severely reduces the drive-ability and value of the vehicle.
