THERE IS A MAJOR ISSUE WITH THE 2015 M274 MERCEDES ENGINE REGARDING THE WRIST PINS. MERCEDES HAS ISSUED NUMEROUS INTERNAL SERVICE BULLETINS ABOUT THE ISSUE. THE ENGINES WERE MANUFACTURED WITH WRIST PINS WITH TOO MUCH TOLERANCE THAT SLAP AGAINST THE PISTON WHEN OPERATING THAT COULD LEAD TO PREMATURE ENGINE FAILURES. THERE ARE HUNDREDS OF COMPLAINTS ON ONLINE FORUMS OF PREMATURE ENGINE FAILURES (PRE 100K MILES). I CONTACTED MERCEDES AND THEY REFUSE TO DO ANYTHING TO FIX THIS PROBLEM THE REPAIR IS WELL OVER $8,000 AND THE AVERAGE PERSON JUST CAN NOT AFFORD IT. YOU DIAGNOSE THE PROBLEM BASED ON CHATTER DURING DECELERATION. PLEASE MAKE MERCEDES MAKE THIS RIGHT AND FIX THE AFFECTED CARS THE RIGHT WAY. I JUST BOUGHT THIS CAR AND I AM NOW IN THE HOLE OVER $20,000

EVERY TIME I START MY CAR IT SMELLS LIKE GAS AND IT'S SO STRONG TO THE POINT WHERE IT GIVES ME HEADACHES. ALSO I WAS ON THE FREEWAY AND THE ROADS WERE WET FROM PREVIOUS RAIN AND I ALMOST DIED AND HYDROPLANED ON THE FREEWAY. EVEN IF IT'S A SMALL BIT OF RAIN MY CAR STARTS SHAKING AS IF I DON'T HAVE CONTROL. I DO NOT FEEL SAFE IN THIS CAR AND I JUST GOT THE CAR A MONTH AGO.

WHILE THE VEHICLE IN MOTION, HEARING A LOUD SOUNDS COMING FROM THE ENGINE. AT FIRST IT'S SOUNDED LIKE A ROCK IN A TIN CAN, LATER IT WAS A SLAPPING SOUND. ABOUT 10 MINUTES LATER FINALLY GOT OFF THE HIGHWAY AND TURNED IN TO MY NEIGHBOR HOOD. AT THE LAST RIGHT TURN, THE CAR SEIZED UP. TRIED TO RESTART NOTHING HAPPENED. GOOD THING IT WAS AROUND 11PM THERE WAS NO TRAFFIC OR AS MANY CARS ON THE ROAD. IF IT WERE IT COULD PROBABLY JUST STOP ON THE MIDDLE OF THE HIGHWAY. THE CAR IS AT THE DEALERSHIP AND SAYING IT NEEDS A NEW ENGINE, COSTING ABOUT 13K. WHICH IS ABSOLUTELY RIDICULOUS, THERE WAS NO SIGNS OF ENGINE PROBLEM, ENGINE LIGHT WASN'T ON. OUT OF NO WHERE, ENGINE LOCKED UP AND I HAD TO PUSH IT HOME.

DONT KNOW WHICH CATEGORY IT FALLS. I BOUGHT THIS CAR IN AUGUST 2015. IN ONE WEEK IT WOULD NOT START EVEN. TOWED TO DEALERSHIP AND THEY SAID, THE GROUNDING SCREW WAS LOOSE. I AM SO SURPRISED THAT A CAR COMES OUT FROM FACTORY WITH A LOOSE GROUNDING ISSUE. IN THE LAST 2 WEEKS, THE CAR JUST STALLED AT THE SIGNAL. ALL LIGHTS CAME UP. I HAD THE ECO START/STOP MODE ON. THIS HAPPENED 3 TIMES AND FINALLY I SHUT THE ECO START/STOP MODE DOWN. IT IS SO DANGEROUS THAT IN HEAVY TRAFFIC, WHEN PEOPLE ARE READY TO DRIVE ON CHANGE OF SIGNAL, THE CAR WONT MOVE, PEOPLE ARE HONKING AND FRUSTRATED AND I AM TOO. LOOKED ONLINE AND SO MANY PEOPLE ARE COMPLAINING THE SAME. THE WHOLE OF DASHBOARD LIGHTS UP LIKE WHEN A CAR STALLS. THIS IS VERY DANGEROUS. ANYBODY WAITING BEHIND YOU CAN TAKE THE PEDAL FROM THE BRAKE AND SMASH INTO YOU. SIMILARLY, FOR LAST 2 MONTHS, I HAVE NOTICED THAT THERE IS A JUMPING NATURE WHEN YOU TAKE LEG OF THE BRAKE AT THE SIGNAL. THAT SCARES ME AS WELL. FROM THE FEEL OF IT, I FEEL THIS IS PRIMARILY A SOFTWARE ISSUE WHERE THE COMPUTER THINKS IT IS IN SOME MODE WHEN IT IS NOT OR SOMETHING AND SHUTS EVERYTHING DOWN AS A PRECAUTIONARY MEASURE OR SOMETHING

ENGINE RANDOMLY STALLS AFTER SITTING AT RED LIGHT/OR WHILE IN TRAFFIC. ALL WARNING/DASHBOARD LIGHTS COME ON AND YOU CAN ONLY START THE CAR BY PUTTING IT IN PARK, THEN PUSHING START. THE CAR HAS LESS THAN 10K MILES. DEALERSHIP CAN'T FIND CODE OR REPLICATE THE ISSUE. INTERNET SEARCHES INDICATE IT IS AN ISSUE AND OTHER MAKES AND MODELS HAVE BEEN RECALLED, BUT WITHOUT A CODE THE DEALERSHIP DOESN'T KNOW WHAT TO DO. I WAS NEARLY REAR-ENDED BECAUSE IT DOESN'T HAPPEN UNTIL YOU TAKE YOUR FOOT OFF THE BRAKE AND PRESS THE GAS TO MOVE FORWARD, AND THAT'S WHEN THE ENGINE SHUTS OFF COMPLETELY. THIS HAPPENS RANDOMLY AND HAS HAPPENED SEVERAL TIMES.
