2016 MERCEDES-BENZ C300 Complaints

THE PANORAMIC SUNROOF SLIDING CLIPS ARE PLASTIC AND BREAK. WHILE GOING DOWN THE ROAD THE ROOF LIFTED WHEN I ATTEMPTED TO CLOSE IT. THE PLASTIC CLIPS BROKE THAT SECURE THE SLIDE RAIL AND GLASS TOGETHER.

ON OCTOBER 15, 2019 AND ON JULY 1, 2020 THE GLASS PANEL WHICH IS LOCATED IN FRONT OF THE PANORAMIC SUNROOF BLEW OFF THE CAR WHILE DRIVING ON THE HIGHWAY. THIS PIECE OF GLASS DOES NOT MOVE AND BECAME A DANGEROUS PROJECTILE ENDANGERING OTHER VEHICLES. I WOULD GUESS THE GLUE IS NOT BONDING PROPERLY

I WASN'T SPEEDING BUT I DID HIT MY BRAKES BECAUSE I WAS ABOUT TO MISS MY EXIT AND MY AIR BAG JUST EXPLODED.

HEARD SOMETHING CRACK AND THE FOUND LATER PLASTIC PIECES OF THE SHOE ON THE RIGHT SIDE ON THE SUNROOF IN THE RAIL OF THE SUNROOF. IT WAS THE RAIL GUIDE SHOE. THE MECHANIC ADVISED ME THE ENTIRE ROOF WOULD NEED TO COME UP, INCLUDING HEADLINER. HE ALSO SAID YOU'D NEED TO REPLACE RAILS, WHICH SOUNDS A BIT MUCH FOR A PLASTIC SHOE. I AGREED, IT'S RIDICULOUS THAT THESE ARE MADE OF PLASTIC. 4 THOUSAND DOLLARS TO FIX IT. I BEEN SEEING A LOT PEOPLE COMPLAINING ABOUT THE SAME PROBLEM.

I WAS DRIVING THEN THE STARTED BEEN HARD NOW IT'S SAYING POWER STEERING MALFUNCTION

THERE IS A VERY STRONG GAS SMELL WHEN THE HEAT AND/OR DEFROSTER IS TURNED ON. THE HIGHER THE HEAT IS TURNED UP'THE HIGHER THE GAS SMELLS. THE SMELL LINGERS WHEN THE CAR IS NOT RUNNING/CUT-OFF. I HAVE NOTICED THAT THE STRONG SMELL OF GAS DOES NOT OCCUR WHEN THE AIR IS TURNED ON'IT ONLY SMELLS WHEN THE HEAT IS TURNED ON. IT IS SO STRONG'IT WOULD LITERALLY KNOCK YOU OUT.
