2015 Mercedes-Benz S-Class owner complaints

The windshield cracks and spreads rapidly without any evidential cause for a crack and yes it would be available for inspection upon request. This is the 5th replacement in 5 years - 2 in one year alone: 1st - At the time of purchase with only 16555 miles (MPI) RBM replaced the windshield. 2nd - 1/21/20 - 40410 miles (Just got home from a drive through car wash and noticed the crack). 3rd - 7/24/20 - 42150 miles. 4th - 8/26/22 - 62274 miles. 5th - 6/18/23 - 77172 miles. Safety was at risk due to nervousness as to what could ultimately happen affecting driving ability. The problem has reproduced itself 5 times. RBM has refused to take responsibility and consistently escalates replacement cost. No warnings or causes leading to cracks/breakage

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

I am writing to report an incident that occurred on Oct 17 2023 involving my 2015 Mercedes Benz S550, where the front portion of the two-part sunroof spontaneously exploded while I was driving down the highway. On the aforementioned date, at approximately 5 pm, I was traveling down Beltway 8 In Houston in my Mercedes Benz S550 along with a pack of cars. Suddenly, without any warning signs or external impact, my vehicle experienced a violent shaking accompanied by an extremely loud popping sound, reminiscent of a gunshot. The intensity of the event startled me, and I quickly maneuvered my car to safety while other drivers also reacted to the sudden disturbance on the road. Once I pulled over and inspected the damage, I was horrified to discover that the front portion of the two-part sunro

The rear passenger door on the passenger side indicate that it is locked, and despite this, it can be opened from the outside without a key or remote.

The gear selector on the steering wheel of the Mercedes Benz has a park button on it when you change the car from gear to park you press that button. That part button has stopped working. It is a safety risk as the car cannot be parked at the end of the driving and it stays in the drive mode. I have to open the door to activate the parking which is built in to the car

And I believe that it exists on all 2014 s550 please address as I almost have had 3 accidents being distracted by this at night driving. Thank you *tr

Windshield was broken october 2016. Replacement windshield made by ppg is defective and has a color reflective strip that in my line of sight. This car cannot be driven at night. They have put 4 ppg windshields in the car and all are bad. Mercedes benz have determined that the glass made by ppg for replacement in the united states is not the same as what is coming out of the factory in germany. I still waiting to try to get correct glass from germany. Mercedes will not ship one out.

Driver rear seatbelt is fully extended and won’t retract. A quick google search shows that this is a common problem with this model.

Both rear seat belts do not retract. This is the second time in 10 months that the seat belts will be replaced by mb in this car. Mb dealers states that it is a problem that is known and mb is working on a fix. In the meantime they are replacing the seat belts with a new part, but they said it may go bad again and mb is working on a permenant fix and we will be notified when a new seat belt is developed.

On july 15, 2020, I was involved in a one car accident. The car left the roadway on a curve when I lost consciousness due to a medical issue, and slid down an embankment into a tree. The tree prevented a total rollover and the car was at a 45 degree angle. I was thrown against the driver's side door and sustained injuries. The side airbags did not deploy, neither did the front airbags. The car was totaled. The side airbags are supposed to deploy in a side impact or rollover situation, both of which occurred. Because they did not deploy, I suffered a head injury, broken ribs from the impact, and lacerations from the broken window and tree. I have enclosed the police report and pictures. The report erroneously stated the airbags had deployed, but the pictures clearly show they did not.

Stopped in traffic on a slight downgrade for a long period of time. Brake pedal was applied firmly, when the truck in front of me would release the pedal slightly to allow the car to drift forward. After several times there were no breaks and the car drifted into the truck in front of us. Had car back to dealer 2 times they claim they can't find anything wrong with it.
