Subject: Report of Spontaneous Sunroof Explosion - Mercedes S580 2022 Model Dear National Highway Traffic Safety Administration, I am writing to report a concerning incident that occurred on [XXX] at approximately [XXX] while I was driving my 2022 Mercedes S580 to work on [XXX] N. During my drive, I experienced a sudden, loud explosion within the vehicle. Initially, I believed it was either a gunshot or that I had been rear-ended. In a state of confusion, I quickly pulled over to the shoulder to assess the situation. Upon closer inspection, I discovered that my sunroof had shattered spontaneously. I am certain that this was not caused by an external object, such as a falling stone. There were no overpasses, bridges, or surrounding traffic that could have contributed to the damage. This was an extremely frightening experience, and I believe it is important to bring this matter to your attention for safety considerations. I have also reported this incident to my local Mercedes-Benz dealership. Thank you for your attention to this serious safety concern. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Over ~3 years of ownership, the vehicle has experienced recurrent electrical and engine-management issues, resulting in 15+ service visits and ~100 cumulative days out of service at an authorized dealer. Patterns include: (1) electrical—keyless entry intermittently unresponsive, instrument cluster flickering/rebooting, multiple warning messages including a battery/electrical icon, HVAC/A/C becoming inoperative without cooling; and (2) powertrain/engine—check-engine light (MIL) illuminated, hesitation/limited power on initial acceleration, and rough operation after start. Safety risk: intermittent failure to unlock/start can leave occupants stranded; loss of power/hesitation creates risk when merging or crossing intersections; multiple warning messages/flicker are distracting; and loss of A/C in hot conditions has required operation with windows down to avoid heat stress. Reproduction/confirmation: The concerns have been observed by the dealer on multiple visits with fault codes recorded (codes UNKNOWN to me). Repairs/updates have been attempted, but symptoms recur after service. The vehicle has been inspected repeatedly by the authorized dealer and remains available for inspection upon request. Warnings/symptoms prior to failure: intermittent MIL, battery/electrical warning, cluster glitches/flicker, and A/C blowing warm air; some events followed periods where the vehicle would not unlock or start on the first attempt. Root cause: UNKNOWN.

mechanical and safety-related failures observed in a Mercedes-Benz vehicle, specifically involving the suspension system, wheels, and braking components. Despite extensive repair efforts—including replacement of all four wheels and tires, complete AWD four-wheel alignment, and diagnostics performed at authorized Mercedes-Benz dealerships—the underlying issues persist. To date, the total cost incurred in attempting to remedy these defects exceeds $15,848. The vehicle and its components have been inspected by two independent Mercedes-Benz dealer service centers and a certified third-party auto inspection firm. All parties have confirmed, through drive testing and diagnostics, that the problems are reproducible and continue to impair vehicle safety and performance. The suspension and associated hardware have been identified as the root cause of instability and braking inconsistencies. These findings align with broader patterns observed in similar vehicles, suggesting a recurring defect that warrants intervention by the manufacturer. Despite clear evidence from multiple independent sources, the manufacturer has failed to initiate a recall or implement corrective measures. This failure poses an ongoing safety risk to operators and the general public. The vehicle remains available for further inspection upon request. Immediate attention to this matter is expected to prevent further liabilities and protect consumer welfare.

The following pictures will again show the issues that I'm having while driving my 2022 S Class Mercedes, while using the cruise control on the Belt Parkway. It shows me stuck in traffic and, although I can only go 11 miles an hour while I’m stuck in traffic, the cruise control wants to push it to 80 mph, which is indeed VERY VERY DANGEROUS!! as you can well imagine. Also, as you can see in the second picture, I have the cruise control set to 39 MPH. I have been writing for the past two months with no resolve as yet. The repair records speak for themselves and still Mercedes Benz offers no remedy. It would appear that it's going to take a severe accident or fatality to bring some type of action on your part to replace this vehicle, which is definitely a LEMON!!

Here we go again, while driving on a side road with a 20 mph school speed limit, the cruise control wants to SPEED UP to 60 mph!! WHAT IS IT GOING TO TAKE TO REMEDY THIS BEFORE I’M INVOLVED IN A SERIOUS ACCIDENT!!

I leased my 2022 S 500, Mercedes Benz. on September 28, 2022 and after about a year, I have had issues with the large screen/radio and cruise control in the vehicle. All events are documented at the Rockville Centre, Long Island service center. I have made numerous complaints beginning in January of this year through emails and was assigned a case number with Mercedes Benz corporate which is 12240831. On numerous occasions, while using the cruise control set to 50 MPH, the vehicle will accelerate to  80 MPH  on a highway with a  50 MPH speed limit. Then on other occasions,  while using the cruise control, the vehicle will accelerate to  80 MPH  on a highway with a  25 MPH speed limit. Then,  at other times, while using the cruise control set to 50 MPH, on a highway which has a 50 MPH speed limit, the car will reduce to 10 MPH .  All of these scenarios are  VERY  DANGEROUS  as you can well imagine. On many other occasions, the screen map will become blurry & distorted causing confusion as to my whereabouts. **The time has come for a replacement/repurchase of this vehicle and,  I believe, at this time, this vehicle should be considered for the  "LEMON LAW"  under all applicable State and Federal laws.   I can send a separate email with all of the pictures of the screen and cruise control issues. 

as a loyal Mercedes Benz customer for the past 15 years, here I am writing to you for the fourth time since January 28th. of this year. My case number is [XXX]. I leased my 2022 S 500, VIN # [XXX] on [XXX] and after about a year, I have had issues with the large screen/radio in the vehicle. All events are documented with your Rockville Centre, Long Island service facility where the staff has been very helpful. On numerous occasions, while using the cruise control set to 50 MPH, the vehicle will accelerate to 80 MPH on a highway with a 50 MPH speed limit. Then on other occasions, while using the cruise control, the vehicle will accelerate to 80 MPH on a highway with a 25 MPH speed limit. Then, at other times, while using the cruise control set to 50 MPH, on a highway which has a 50 MPH speed limit, the car will reduce to 10 MPH . All of these scenarios are VERY DANGEROUS as you can well imagine. On many other occasions, the screen map will become blurry & distorted causing confusion as to my whereabouts. On a side note, we had an usually warm day [XXX]. here in New York City of about 55° and while riding around NY City, the air conditioner was not cooling properly and was brought in for service shortly afterwards for that issue as well as all of the screen issues. The same problem with the air conditioning occurred last week as the temperatures in New York City were about 55° and, frustrated again, I brought the vehicle in for the air conditioner and screen issues and they kept the vehicle for ten (10) days!!. **The time has come for a replacement/repurchase of this vehicle and, I believe, at this time, this vehicle should be considered for the "LEMON LAW" under all applicable State and Federal laws. I will be sending a separate email with a few pictures of the screen issues. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
