Other Fuel System Problems of Mercedes Benz S550

I purchased this vehicle in July 2020. I did a through check for recalls, warranty problems and could not identify any with this vehicle. From the get go the check engine light would come on. I checked the codes and they indicated an "electrical fault on bank 1, oxygen sensor 1. I replaced the wiring harness on that sensor as well as the sensor. From then until now the car would code weekly about the same issue. Eventually I started using a catalytic converter cleaner (it cleans off sulfur deposits) in an attempt to solve the issue. It would work for a couple of tanks of gas and then continuing coding. I asked mb on numerous occasions about what the issue was. They all said they had no idea. It looks to me like they knew what the issue was, but kept it to themselves. Several weeks ago I received a letter in the mail(not dated by postmark) but the letter was dated August, 2023. The letter outlined an issue with the catalytic converter system identifying my vehicle by VIN. The same problem I have had all along. The letter came at a time when the car codes almost daily with the same issue as always, only now the vehicle stalls occasionally while waiting at stop lights. I said great. I called to get an appointment to fix the issue only to be told that the fix window had passed. I told them that I just got the letter. They told me that the fix expired in December 2023. I called mb hotline at 1-800-367-6372 to see what was up. They said they would get back to me in 3 days. It's been a week so I called again and they advised me they can't help. It's an issue for the 2011, 2012, 2013, and 2014 mb S550 w221. Why is this not a recall and why won't they fix it. It's an expensive repair. They sent me the letter and said it was expired 6 months before I received the letter. Can you help?.

I was sold a vehicle by a dealership with a busted gas tank. It appears to have been an attempt to repair it with patching material.

My safety is at risk because of leaking gas that could potentially ignite and inhaling strong gas fumes that could impact my lungs and health. The fuel tank damage has been confirmed by a mechanic and documented. It has not been inspected by any other entity while in my possession other than reported inspection by the dealership. I secured the vehicle on [xxx] from the dealership with these safety concerns.

Upon refuling my automobile full I could smell a strong odor of gas fumes. Earlier that day I had an impact of my tire over a curb. Gas fumes could be smelled not so much on the outside of the auto but inside without abatement. Upon inspection by Mercedes Benz of stockton CA it was determined a fuel leak was present with the cushion that sits on top of the fuel system was soiled/sturated under the rear passenger seat of the car. Pictures taken suggest it had been was ongoing possiblely for years. They suggested heat contributed to the unit-seal corrosion and its surroundings. It is not clear why my right rear impact with a curb brought this all to my attention. Highly combustible situation that was clearly not detected witch is not completely understood the same day I have an impact to the right rear tire jumping a curb then going back over it to unlodge the tire & rocker molding from the curb & refuel I smell gas fumes. Highly dangerous using plastic secure gas exchanges on something people sit on? has simularities in other drivers. Not sure why that day the seal (plastic) ruptured (at plastic lid).
