ELECTRICAL SYSTEM

Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

Windermere, FL

POWER TRAIN

Vehicle: 2022 Mercedes-Benz S580 The vehicle is experiencing a severe and violent drivetrain "jolt" or "push" during gear transitions, specifically when shifting from 5th to 6th gear at cruising speeds. On multiple occasions, the jolt was so forceful that passengers believed the vehicle had been rear-ended by another car. This behavior is unpredictable and creates a significant safety hazard, as it causes a sudden change in vehicle momentum while driving in traffic. The issue has been reported to the authorized dealer (Fields Mercedes Lakeland) multiple times. The dealer kept the vehicle for over 40 cumulative days and performed motor/transmission mount replacements and "software calibrations," yet the violent shifting persists. Additionally, the engine produces an excessive vibration and loud noise during extended operation in high temperatures, which ceases only when the ECO/Auto-stop mode engages. I am concerned that the transmission or torque converter may fail abruptly while at highway speeds, potentially leading to a loss of propulsion or a rear-end collision due to the unexpected deceleration/jolt behavior. The vehicle is suffering from chronic oil consumption issues. The 'Check Engine Oil Level (Add 1 Quart)' message has appeared twice: once on 10/31/2025 and again on 04/17/2026. This is despite the vehicle being exclusively serviced by Mercedes-Benz Lakeland. This recurring engine issue, combined with the violent drivetrain jolts and shifting failures, significantly compromises the vehicle's safety and reliability."

SERVICE BRAKES

On multiple occasions, after the vehicle had been parked and not driven for approximately five days or more, the automatic parking brake locked in place and would not release. I attempted standard methods to disengage the brake, including manual release procedures and lightly rocking the vehicle, without success. The only way to release the brake was to apply significant pressure to the accelerator while in reverse, which caused the brake to suddenly unlock. The first incident occurred while the vehicle was parked in my home garage. At the time, my grandson was playing nearby. The sudden release of the brake after applying the accelerator created a dangerous situation and was extremely alarming. A second incident occurred several days later while I was on vacation. In this instance, I made sure no one was near the vehicle before attempting to release the brake. Anticipating the issue, I had my left foot ready to push on the breaks when I accelerated using my right foot which releases the parking. I brought the vehicle to a Mercedes-Benz dealership on January 5, 2026, where the car remained for nearly ten days. The dealership was able to replicate the issue exactly as described. The service advisor also had to apply significant accelerator pressure to release the locked parking brake. A certified Mercedes-Benz technician inspected the vehicle thoroughly, including scanning for fault codes and checking for rust or mechanical issues, but ultimately advised that this behavior was considered “normal operation.” I find this explanation concerning. Having to apply forceful acceleration to release a locked parking brake presents a clear safety risk, particularly in confined spaces such as garages or parking structures, and could easily result in property damage or personal injury

WHEELS

Mercedes-Benz S580 equipped with 21-inch wheels has experienced numerous tire blowouts over the course of ownership — too many to count. The blowouts occurred during normal driving on typical roads. Several blowouts caused rim damage and created a dangerous situation, including moments where I nearly lost control of the vehicle. This appears to be a design defect involving the 21-inch wheel and low-profile tire configuration, which seems structurally inadequate for normal road conditions. The failures are recurring and not due to isolated hazards. Other S580 owners have reported identical issues with repeated blowouts on 21-inch wheels. This presents a serious safety hazard, and a permanent remedy is needed.

UNKNOWN OR OTHER

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.

STRUCTURE:BODY

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.

WHEELS

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.

ELECTRICAL SYSTEM

Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

Check engine light came on few occasions. Took to the dealer and told it’s just a false alarm no problems. On the night of sept 12th 2024, I’m my way home I lost the ac cooling all of a sudden. I was only 5 mts from home. Once inside my garage I saw to my horror some smoke coming from under yhe hood. Upon opening saw some charred wires and some wire smoldering and smoke was coming out of it. Scared for my family I parked my car outside overnite and called the dealer. They had the car towed away the next day. Got my car back on 6 th of November 2024, with a laundry list of problems and issues, that they had supposedly fixed. Three or four various engine wiring harnesses were replaced, due to charring or melting, probably due to the heat. The engine and transmission were lifted off to fix all the wires and what not. I have all the invoices. And video and pictures of some wires and smoke. They don’t have an explanation for this. The recent recall about ecu maybe suggests the overheating of engine and causing the wires to burn out and some wires started burning almost causing fire if not caught in time. Called Mbusa and they didn’t show any concern. But one week after this incident they issued that ecu engine heating warning. Off course there is no repair for that. This is a fire hazard waiting to happen.

SERVICE BRAKES

Brakes seize when wet. That is, after a car wash or following exposure to rain, the accelerator must be pressed with abnormally greater pressure to get car moving from parked position. Loud, screeching sound emanates when brake releases. This malady continues severally. Resting lightly on brake pedal to dry out turning brake rotors, does not help. Eventually, problem disappears until the next wet episode. -Per Mercedes Authorized Dealer, there is no fix; problem is common to Mercedes 223 series. -Risk of collision exists in both modes, Drive as well as Reverse. This, due to sudden jump forward or rearward under brake-seize conditions. -Issue is ongoing, not a single incident. Remains unresolved. [At age [XXX] , I have over [XXX] driving experience. The above is an abnormal-with-risk, issue.] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
