I AM IN AN MBFOURM AND I AM STARTING TO HEAR OF ENGINE FAILURE AT AN EARLY AGE. I HAVE NOT EXPERIENCED THIS, YET. BUT, FROM WHAT I AM READING IN THE FORUMS, A LOT OF PEOPLE WITH THE SAME MODEL ENGINE I HAVE IN MY 2017 MERCEDES E300 ARE HAVING ISSUES WHERE THE PISTON CRACKS AND THEY NEED A NEW ENGINE. MERCEDES ISN'T PAYING FOR ENGINE REPLACEMENTS AND IT IS ALL OUT OF POCKET COST. I AM WORRIED THAT ONCE MY WARRANTY IS OVER AND MY ENGINE BLOWS BECAUSE OF MERCEDES DESIGNS FLAW, I WILL END UP SPENDING 9-10K FOR A NEW ENGINE BECAUSE OF A DESIGN FLAW.

I STOPPED FOR A RED LIGHT, I SAW A POP UP ON THE DASHBOARD THAT READ 'BRAKE ASSIST DISENGAGED'. AT THAT POINT THE CAR SHUT ITSELF OFF. I TRIED TO RESTART WITH NO SUCCESS, IT WOULDN'T EVEN TRY TO TURN OVER. AFTER SITTING IN TRAFFIC FOR ABOUT THREE MINUTES UNABLE TO RESTART THE CAR, I JUST KEPT HITTING THE START / STOP BUTTON AND IT FINALLY TURNED OVER AND STARTED. I REPORTED THIS INCIDENT TO THE DEALERSHIP AND WAS TOLD THEY WOULD WORK ON THE CAR IF IT HAPPENED AGAIN! IF IT HAPPENS AGAIN IT COULD RESULT IN A MUCH WORSE OUTCOME. I WAS DEAD IN TOWN TRAFFIC, HEADING STRAIGHT THRU A RED LIGHT AFTER A COMPLETE STOP.

AFTER ABOUT 1-2 MIKES OF DRIVING MY 2017 MB E300 STARTED JERKING AND ENGINE LIGHT CAME ON WHEN I DROVE TOWARD THE FIRST LANE FOR A LEFT TURN ON A BUSY HIGHWAY INTERSECTION. I ALSO FOUND THE GEAR WAS CHANGED TO NEUTRAL. I TRIED TO CHANGE THE GEAR TO DRIVE WHILE WAITING FOR THE TRAFFIC LIGHT BUT I COULDN'T. I STOPPED THE ENGINE TO RESTART BUT COULDN'T RESTART AT ALL. I PRESSED THE MB ROADSIDE ASSISTANCE BUTTON. THEY SAID A TOW TRUCK WOULD BE THERE WITHIN 20 MINS. IN THE MEANTIME SOMEONE HELPED PUSH THE CAR TO MOVE IT TO THE SIDE BUT THE GEAR DIDN'T STAY ON NEUTRAL. IT KEPT GOING BACK TO PARK. THEN IT DIDN'T GO TO NEUTRAL ANYMORE. I GOT STUCK IN THE MIDDLE OF THE ROAD. THERE WAS NOTHING ELSE I COULD DO BUT PATIENTLY WAITED FOR TOWING WITH MY LITTLE KID INSIDE THE CAR WITH AN EMERGENCY LIGHT ON AND 4 WINDOWS OPEN. THE CAR WAS HEATED UP WITH THE OUTSIDE TEMP OF OVER 90F. MY KID WAS GETTING EXHAUSTED AND DROWSY DUE TO A HIGH TEMP OF 110F INSIDE THE CAR. I PRESSED THE ASSISTANCE BUTTON AGAIN AFTER WAITING ALMOST 40 MINS AND EXPLAINED ABOUT AN URGENT SITUATION. THEY SAID THEY WERE STILL SEARCHING FOR A PROVIDER AND WOULD TEXT ME ETA OF A TOW TRUCK ONCE THEY LOCATED IT. COULDN'T BELIEVE WHAT THEY SAID. MY KID WAS ALMOST PASSING OUT FROM THE HEATSTROKE. I STARED LOOKING FOR OTHER WAYS TO TOW MY CAR WHEN I FINALLY GOT A TEXT FROM THE ROADSIDE SERVICE SAYING A TRUCK WOULD BE THERE IN 50 MINS. OMG! THEN A LADY STOPPED HER CAR NEXT TO ME. SHE GAVE US WATER, LET ME MOVE MY KID INTO HER CAR WITH COOL AIR, CALLED HER AAA, AND LET ME USE THE SERVICE. AAA SHOWED UP IN 15 MINS AND TOWED MY CAR TO THE MB DEALERSHIP. I WAS MORE DISAPPOINTED WITH MB ROADSIDE SERVICE THAN THE CAR BREAKDOWN. WHAT'S THE PURPOSE OF THE BUTTON? WHY DID THEY INSTALL THE USELESS BUTTON IN THE CAR? IF IT WASN'T THERE I WOUNDN'T PRESS IT AND WASTE ALMOST 1 1/2 HRS ON THE STREET! MY KID COULD HAVE DIED IN THE CAR!
