2016 S550 front roof panel issues. Adhesive issues.

Started car in parking lot and warming light read zero air in right front tire. No prior warning. Checking tire for any road hazard - nails or other potential punctures but none were present but the tire had a hole just below the wheel that had blown out. The tire is a Pirelli P Zero 245/40R20 Run Flat. Was able to drive it to Tire Discount the next day to replace the tire. Manager checked tire and could not find any other issue with the tire. They were supposed to hold the tire but it was removed by the recycling company. I have pictures and the managers examination. Our safety any others if the split in the tire would have blown at speed in traffic. Called and emailed Pirelli and they could care less about a safety issue. Just told me it was out of warranty because it was over 1 year old. The tire has approximately 5,000 miles on it.

Rear left seat belt is stuck and won’t retract. Seat has not been used much. Vehicle is a 2016 with 65,000 miles.

The car's front passenger passenger seat buckle fails to properly secure the seat belt. After inserting the seat belt it fails to latch into the buckle. The Mercedes dealer has examined the seat buckle and determined that it failed. They are recommending a replacement.

Staggered tires on this car Goodyear Eagle F1 Asymetric 2 Run flats. Front size - 245/40 R 20/99y, Rear -275/35 R 20/102 These tires cannot take the load of the car . I purchased the vehicle & the same tire (front driver side) has blown & ripped open over a moderate pothole, Aug 2020 & in Sep, 2022. In my opinion these tires are massive liability and a huge safety hazard. These are Summer runflat tires & also there no Allseason ROF's

On cold days below 40 degrees, my 2016 Mercedes S550 W222, trunk lid when closed using the close button on the trunk lid closes and immediately reopens. It will only stay closed if I tie it down with a rope or elastic cord. I found a work around if I am home and apply heat to the latch with a hair drier and spray the latch with silicone lubricant spray. This problem is identical to Mercedes Campaign No. 2019030005, April 2019, which applies to S-Clsss 222 platforms Model Year 2018-2019. I request that this campaign be extended to Model Year 2016 and my car. I have attached copy of Mercedes Campaign No. 2019030005, April 2019.

While driving or even sitting this piece gets extremely hot and has actually burned me twice. As soon as the car is turned on the temperature rises on this piece that’s on by the arm rest

Catalytic converters are factory defective My vehicle has less than 80K miles and used as pleasure vehicle. The problem has been inspected and confirmed by a reputable independent service provider.

Failure of LED instrument cluster. 2016 S550. No display. In October 2020 I had total system failure in my garage. Battery discharged down to +/- 5V. The car was still under warranty. Tech arrived and tried to recharge battery. He did not have the proper equipment, (his statement). I had to use two of my chargers in parallel plus his to get car back to life. He disconnected the battery from car to get there. Battery came back to life. Everything seemed to work. Started to drive car and experienced random IC failure. There were times when cluster worked fine and suddenly it went blank (black). Contacted dealer and was told that I should keep on driving it would fix itself. Dealer had the car for a week and could find no fault. And it fixed itself. Great!!! Note, at this time the car was still under Warranty. Forward to June 2022. I replaced Batteries. As in 2020 display died (black) randomly. This time it was more often black than alive, it does not want to recover. Note, every time the display dies I loose all indications, no speed indicator plus anything else. No steering wheel controls. No sound of directional indicator (blinker). Dangerous to drive. It can happen at any time. It can work when I drive off and stop!!! Note, this I find very interesting, there is no failure code anywhere, not in the diagnostic Xentry either. That for my opinion is a design problem. Dealer uploaded some code into cluster. Told me it is working. Came to pick up car, SA brought me the car and to

On Feb 26, 2022 between the hours of 4:00 am and 5:15 am the Sunroof on my 2016 S550 Mercedes Benz shatter for no cause or reasons while driving on the main highway. When the loud bang accrued while driving I immediately pulled the car over to exam the issue and I noticed the Sunroof glass had shattered. I was able to drive the S550 Mercedes Benz to my residence. However, this Sunroof Shattering could have a cause major issue if the lower cover to my sunroof was open. I would strong recommend Mercedes Benz reach out to the glass manufacture concerning this safety issue with defective glass (Shattering Glass Sunroof for no cause or reasons)

I WOKE UP ONE MORNING AND WAS ASTOUNDED TO FIND A LONG DIAGONAL CRACK ACROSS THE PANORAMIC SUNROOF OF MY 2016 MERCEDES-BENZ S550. I CONTACTED MERCEDES AND WAS TOLD TO BRING THE CAR TO A DEALERSHIP FOR EVALUATION TO DETERMINE WHETHER THIS WAS DUE TO OUTSIDE INFLUENCE OR A MANUFACTURER'S DEFECT. THEY DETERMINED THAT IT WAS A "STRESS CRACK" AND STUCK ME WITH A BILL FOR $13,000. THIS IS A 2016 MODEL CAR WITH 50K MILES ON IT WITH A SUNROOF THAT SPONTANEOUSLY CRACKED. WHAT IF MY WIFE AND YOUNG CHILDREN WERE IN THE CAR WHEN IT STARTED TO CRACK? THE RESPONSE FROM MERCEDES IS UNACCEPTABLE. THIS IS A VERY DANGEROUS MANUFACTURER'S DEFECT WHICH MUST BE ADDRESSED BEFORE SOMEONE GETS SERIOUSLY HURT.

TAKATA RECALL. I WAS DRIVING ON THE HIGHWAY ON MY WAY TO PHOENIX AZ TO DROP OFF MY MOM AND GRANDMA WHEN SUDDENLY THE SUNROOF EXPLODED. IT SOUNDED LIKE A GUN SHOT. THERE WASN'T ANY TYPE OF OBJECT NEAR ME TO CAUSE IT. IT WAS VERY RANDOM. THIS DISTURBED MY FAMILY MENTALLY SCARING THEM AND I SWERVED OFF THE HIGHWAY ALMOST CRASHING.

I AM REPLACING THE WINDSHIELD FOR THE 3RD TIME, SMALL STONES CREATING HUGE CRACKS, SEEMS VERY UNUSUAL FOR IT TO HAPPEN SO OFTEN.
