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.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
