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.

My vehicle is listed in this Mercedes recall campaign bulletin, and it is also experiencing the safety issue that is discussed in this recall campaign bulletin: Campaign No.2021070010, August 2021 Revision A 09/03/2021 When I contact Mercedes to have the issue addressed, they stated my Vin is not a part of this recall campaign, and to contact you about it.
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.
visibility 3 complaints shown
Heard a loud bang while driving down the highway and didn't know what it was until returning home and looked up and saw the rigid crack from front to the back on the panoramic glass. There are no indications of debris hitting the glass as there are no chips.
Vehicle's front windshield spontaneously cracked overnight while vehicle as parked in a locked private garage. Crack originates at top of windshield frame where body torques the glass and continues through advanced driver assistance systems, ending up in driver's line-of-sight. No visible point of impact on damaged area of glass. Driver assistance and safety systems are affected by the stress crack, rendering them non-functional. Dealer investigated and determined that stress crack was due to a defect in manufacturing and installation of the glass, not due to any impact or road debris. However, manufacturer denied coverage under new vehicle warranty (4yr./50,000 mi), stating that glass defects are only covered for 1 yr/12,000 mi. *tr

wheels 2 complaints shown
I have now experienced cracks on three separate tire rims. The car has less than 41,000 miles.the tires are low profile, run flat tires and the rims appear to be aluminum and faulty.
I got this certified car from Mercedes Benz dealer. I have driven it sparingly for less than 10K miles without really any hitting any bumps or potholes . After a recent service [XXX] 2024 at a MB dealer, I was told that 2 wheels were cracked 1 front & 1 back . I took it to another MB dealer (MB Morristown, NJ) to change the wheels & they advised that all 4 wheels were cracked, & one wheel had 3 cracks. These are premium AMG staggered wheels & without a doubt there is genuine design issue or defect to wheels which at high-speed could crack & crumble causing major injury & destruction to property. I have all the service records regarding this issue INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2016 Mercedes cls550... I bought this car used and I've had it for about 6 months. I've already had a seizure in the car and was found slumped over by florida highway patrol at a dead stop with the car running and the air on and I woke up in the hospital. Something is wrong with the air conditioner causing carbon monoxide poisoning is the only thing that I can put together. The hospital obviously would not think that it was because of my air conditioner. They did a cat scan everything fine . They did a covid test everything and I was cleared and out the door in 5 hours. I have put this together and figured it out myself. I've had nothing but a foul sour disgusting odor coming through my air conditioner and I have almost passed out on three other occasions same exact feeling up until I had

My steering deactivates and totally locks out while driving. I do get warning messages and it comes on when the steering deactivates and then goes out its like intermittent sometimes I wont have steering at all for a few minutes and sometimes it just goes in and out. MBUSA has an active recall on this very issue but my car even though it was built in the time frame they say other cars have been built they are not willing to fix it. It has been inspected twice and the dealer has verified the steering rack needs replacement, they still wont fix this. The message that comes on is power steering Malfunction see owners manual. When this locks out i get other items that wont work either like lane departure assist and blind spot inop lights. This started happening slowly roughly a year ago but it

cruise control 2 complaints shown
Wheel speed sensor failure reoccurring constantly on vehicle, others seem to have same issue. Reoccurs due to part failure I would suggest. Causes dangerous conditions with ABS and traction control failure.
From 2014 through 2016 the intelligent drive and the driver assistance package does not work. I keep saying the s550 thinks 200 feet is 90 feet and 100 feet is 30 feet. What I mean to say is the systems think 90 feet distance is 200 feet away and 30 feet is 100 feet away. It does not measure the distance properly. It could be, and most likely, a programing issue. It is the same on all the 2014 through 2016 s550's I have tried. The other thing it does with the distronic cruise control is when it starts to brake, the distance set decreases and the car speeds up and again the distance set decreases and the car speeds up and so on. It changes the distance ( you can see it happen in the in the menu setting on the speed and tachometer screen) as soon as the car autonomously brakes. Set it at
tires 2 complaints shown
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
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

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 s
