CRANK PULLEY/HARMONIC BALANCER WAS REPLACED AND STILL HAVE VERY BAD DANGEROUS VIBRATION ALL THE TIME
20170421ELECTRICAL SYSTEM
ALL ELECTRICAL WENT OUT, IN MOTION ON CITY STREET, THEN PULLED OVER. HAD KEY IN MY POCKET. ENGINE STAYED RUNNING AND COULD NOT TURN OFF WITH BUTTON OR BY KEY. GOT OUT OF OF CAR, CLOSED DOOR AND COULD NOT GET BACK IN ANY DOOR EVEN THOUGH DRIVER DOOR WAS NOT LOCKED (BUTTON UP). ENGINE CONTINUED TO RUN UNTIL COOLANT EXPANSION TANK EXPLODED. IF CHILD WOULD HAVE BEEN IN BACK, WOULD HAVE HAD TO BRAKE WINDOW TO GET IN. THIS IS A BIG SAFETY ISSUE WHEN SO MANY OPTIONS DEPEND ON CAR'S ELECTRICAL WORKING. MERCEDES SAIL ELECTRICAL SYSTEM FAILED CAUSING OVER $15,000 IN DAMAGE CAUSE I WAS UNABLE TO CUT ENGINE OFF. I HAVE SOLD THE CAR, BUT BELIEVE IT'S IMPORTANT TO HAVE SUCH A SAFETY ISSUE INVESTIGATED.
