ENGINE

ML320 BLUETEC, RANDOMLY LOSES POWER. THE POWER WILL BE RESTORED ONCE THE CAR IS TURNED OFF AND ON AGAIN. CAR HAS BEEN TO THE DEALER 7 TIMES FOR REPAIR OF THIS ONE ISSUE, INCLUDING TWICE IN A STATE WITH LIMITED POWER. DEALER HAS DONE MULTIPLE SOFTWARE UPDATES, TURBO REPLACEMENT, EXHAUST VALVES REPLACEMENT AND THE ISSUE IS STILL PRESENT. ON ONE OF THE LAST OCCASIONS THIS HAPPENED, THE CAR LOST POWER WHEN TRYING TO MERGE ON TO THE HWY. THIS ALMOST RESULTED IN ME BEING REAR ENDED BY A BIG RIG. LUCKILY I WAS ABLE TO PULL TO THE SHOULDER BEFORE I WAS REAR ENDED. THIS IS SERIOUS SAFETY CONCERN THAT NEEDS TO BE ADDRESSED AND RECTIFIED. AS OF 02/17/2014 THIS ISSUE HAS NOT BEEN CORRECTED.

ENGINE

THIS CAR SHOULD QUALIFY AS A LEMON. WE SPENT OVER $65K ON IT NEW IN JANUARY OF 2009 AND IT HAS EASILY COSTS US $65K TO KEEP IT RUNNING SINCE. SOMETHING SIGNIFICANT BREAKS ON IT EVERY 60 DAYS SINCE OWNING IT. THE TURBO WENT OUT MOST RECENTLY AFTER A BAD OIL SEAL LET OIL INTO IT. $6500! THE CAR MAY HAVE SADLY BEEN CURSED SINCE DAY ONE. OUR SALES PERSON AT MERCEDES BENZ OF SF DIED RIGHT AFTER WE BOUGHT IT. THINGS STARTED TO BREAK IMMEDIATELY AFTER. PEOPLE RAN INTO IT, ETC. IT HAS BEEN THE WORST CAR OWNER EXPERIENCE IN MY LIFE.
