Brought my vehicle to my mechanic because of noise that recently appeared in my car. To my surprise the mechanic stated that my engine is completely failing and would require an entire new engine. I purchased this car less than two years ago with an estimated 79,000 miles. Vehicle currently has an estimated 112,000 miles. Never missed a service interval for the vehicle. Now several components of the engine are completely failing.

THE RIMS ON THE CAR CRACKING. I REPLACED THE RIMS IN THE TWO FRONT WHEELS AND NOW THE RIGHT REAR RIM IS CRACKED, I HAVE REPORTED THIS PREVIOUSLY TO YOUR COMMISSION INCLUDING SENDING PICTURES. THE DEALER DOES NOT WANT TO ACCEPT RESPONSIBILITY. IN THE FUTURE PROBABLY THE 4TH WHEEL RIM WILL HAVE THE SAME FATE.

Roof panel between windshield and panoramic sunroof has developed fine hairline fractures on the polycarbonate panel. Why wasn't my vehicle included in recall 21V-197? Thanks for your time.

MY WIFE WAS DRIVING MY 2015 MERCEDES BENZ S-550 ON THE 14TH OF AUGUST, 2019. SHE HAD STOPPED AT A RED LIGHT AND WHEN IT TURNED GREEN CROSSED A 6 LANE INTERSECTION. SHE WAS MOVING THROUGH THE INTERSECTION WHEN SHE WAS HIT BY A VW PASSET WHO RAN THE RED LIGHT AT AN ESTIMATED 40 TO 50 MPH. THE PASSET HIT DEAD CENTER ON THE B PILLAR BETWEEN THE DOORS ON THE PASSENGER SIDE OF THE MERCEDES. ALL AIR CURTAINS AND A REAR SEAT AIR BAG DEPLOYED ON THE UNOCCUPIED PASSENGER SIDE OF THE CAR, NONE DEPLOYED TO PROTECT DRIVER'S HEAD ABEAM THE B PILLAR.. MY WIFE'S HEAD WHIPPED VIOLENTLY TO THE RIGHT TOWARDS THE CRASH, THEN WHIPPED BACK VIOLENTLY TO THE LEFT HITTING THE LARGE SEAT BELT RETRACTOR PROTRUSION BUILT INTO THE B-PILLAR. SHE WAS BRIEFLY UNCONSCIOUS AND SUFFERED A SEVERE CONCUSSION AND MAYBE MORE AS MEDICAL TESTS ARE STILL ON GOING. IN ADDITION, SHE SUFFERED 4 HERNIATED DISCS IN HER NECK, 2 SEVERE. SHE ALSO SUFFERED AN ACUTE HERNIATED DISC IN HER LOWER BACK AS WELL AS NOW HAS SOME TMJ ISSUES WITH HER JAW AND HAS TO WEAR A MOUTHPIECE TO SLEEP. NO AIR BAGS OR SIDE AIR CURTAINS DEPLOYED ON THE DRIVERS SIDE OF THE CAR, THAT WOULD HAVE HELPED PROTECT HER HEAD AND LIKELY LESSENED THE SIDE TO SIDE WHIPLASH CAUSING THE HERNIATED DISC ISSUES. WHEN I CALLED MERCEDES BENZ TO INQUIRE WHY NO DRIVERS SIDE AIR CURTAINS OR AIR BAGS DEPLOYED, I RECEIVED A LETTER BACK SAYING THEY WERE NOT DESIGNED TO DEPLOY IN THIS CASE THE CAR, WAS A TOTAL LOSS WITH A $65,000 SETTLEMENT CHECK. MB IS SAYING ONLY THE SIDE CURTAINS ON THE SIDE THE CRASH OCCURRED DEPLOY IN THIS CASE PROTECTING NO ONE. AT THIS HIGH RATE OF SPEED, WITH MB STATING IN A LETTER THAT THE CAR'S AIR BAG PREFORMED AS PROGRAMMED, I THINK THERE IS A MAJOR SAFETY FLAW THAT LIKELY HAS CAUSED OTHER SERIOUS INJURIES OR DEATH.

I bought my S-class car at a Manhattan dealership with 4900 miles on it, I treated it like my baby I’m the only driver and all services and maintenance had been done at the dealership, and I started getting bad readings on the fuel, check engine is ON, fuel gauge reads Full then goes down to Empty The mechanics at the Manhattan dealership said it was short on the fuel tank and I need to have the whole new tank replaced, my understanding is this model, the S Class has been having this issue on many models and there was a soft recall on that matter and it can be fixed at the dealership, we do have a case number with the Dealership. case number 03656172
