When owners complained

A spike years after the car went on sale usually means a part wearing out on schedule across the whole fleet — the kind of pattern no single owner can see from inside their own car.

ELECTRICAL SYSTEM

In multiple incidents, the tailgate has begun to close while I am loading or unloading items from the trunk, hitting me in the head. My natural reaction is to lift up, causing injury to my neck. The dealer unsuccessfully "fixed" the problem. Additionally, and unrelated to the closing problem, on multiple occasions, upon pushing the close button on the tailgate when it was in an open position, the tailgate reaches the floor of the trunk, then without locking, opens about one (1) foot. The dealer "could not duplicate" the problem. I have to manually close the tailgate. You ask when did this happen, the latest incident is the date reported below, but the two issues/problems have reoccurred time and time again since we bought the vehicle new.

SEATS

When I entered my vehicle after it was washed at the Mercedes-Benz service location, I pressed Memory 1 button and the seat returned to my normal position. Without any further input, I started the engine, and the driver's seat automatically moved backward by itself. When I readjusted the seat and shifted into Drive, it continued moving rearward. As the seat moved backward, my feet could no longer reach the brake pedal. At the same time, the car began to move forward, and I lost control of the vehicle, resulting in a collision that damaged the right side doors. This malfunction occurred suddenly and without any warning lights or messages. The seat moved by itself twice-once when the engine started and again when I shifted into Drive. The issue appears to be related to the seat's electrical control system or memory setting malfunction. The dealership has inspected the vehicle but was unable to determine the cause of the problem. I am deeply concerned that this may happen again and could cause a serious injury or major traffic accident. The vehicle has approximately 2200 miles and was purchased new in March 2025. I am requesting a formal investigation to determine the cause of this automatic seat movement and whether other vehicles of the same model are affected.

ELECTRICAL SYSTEM

My vehicle's infotainment system both center console and dashbboard went completely black 2 weeks after I purchased the car in August of 2025. The vehicle was in the shop for a week and a half, and they finally fixed the issue. The vehicle at the time was bought used with about 2,200 miles on it at time of purchase. Now in July of 2026, exactly one year from the day i bought the car, with only 9,500 miles on it, we are having the same issue again with both the dashboard and center console going completely dark, not allowing us to see any critical information such as MPH, gas fuel, tire pressure, etc. Other than that the car seems to drive just fine. I noticed there was a mass recall of 144,000 cars because of this same issue with Mercedes Benz. The GLC-class was in fact listed on this list of eligible recall vehicles. However my VIN # was not eligible for some reason, even though it is the exact issue that the recalls were happening on, and fits within the recall class type and year of manufacture (2024-2026). I am simply requesting to be put on this recall list because it seems like this issue will continue to persist and we do not want to be turning this in every year and also risk our lives driving a car that does not give us very critical information in order to drive safely.

The entire main console display AND the digital instrument cluster screen have completely frozen. Additionally, the gas gauge for how much fuel is in the vehicle is nowhere to be found. Temperature touch controls (no physical option), volume, car settings (which can adjust safety features, multimedia features, accessibility features), etc. are all completely unavailable and unable to use. For example, if the defrost option was on which defaults to full blast heat, I would’ve unable to turn it off. The only information that is properly updating is MPH, headlamp status, time, Emerfency brake, Gear, and outside temperature. RPMs cannot be seen.

ELECTRICAL SYSTEM

The contact owns a 2025 Mercedes-Benz GLC300. The contact stated that while driving approximately 30 MPH, there was an abnormal grinding sound coming from the vehicle. The contact stated that the brake assist suddenly activated and the vehicle came to an abrupt stop, causing the seat belt to immediately retract and lock. The contact was slightly jerked from the abrupt stop. The contact stated that a warning light with a red triangle with an image of a crash in the center was illuminated. The contact stated that after starting the vehicle, the infotainment center and the instrument panel were completely black. The vehicle was restarted several times before both systems started operating as needed. The failure occurred twice; however, the second time, the contact had to turn off and restart the vehicle for approximately an hour before the infotainment center and instrument panel became operational. The vehicle was taken to the dealer, who performed a software update for the infotainment center. After the software update was completed, the contact became aware there were other electrical systems that failed intermittently, including the voice activation system. The vehicle was returned to the dealer and the contact was informed that the front driver’s and passenger’s sides sensors were too low and there was no reason for the notification to become activated. The vehicle was not diagnosed or repaired. The manufacturer was informed of the failure, and a case was opened. The failure mileage was approximately 2,000.

Fort Lauderdale, FL

SEATS

The driver’s seat automatically adjusted while the vehicle was in drive, causing me to lose the ability to reach the pedals and almost resulting in a collision. While driving my 2025 Mercedes-Benz GLC 300 4MATIC with my children in the car, I stopped at a stop sign when the driver’s seat suddenly began adjusting itself backward. My husband also drives this vehicle, and because I had not logged into my driver profile, the car began moving the seat and controls to his saved position, while the car was in drive. The seat moved so far back that I could not reach the pedals. I lost control of the vehicle while another car was turning into my lane. The only way I avoided an accident was by quickly putting the car into park before the seat adjustment completed. This was a terrifying and dangerous situation. Automatic seat adjustments should never be allowed while the vehicle is in motion or in drive. This design flaw puts drivers, passengers, and surrounding traffic at risk of serious injury or death

ELECTRICAL SYSTEM

In July 2023, I entered into a lease agreement for a 2023 Mercedes-Benz GLC 300 4MATIC SUV (VIN: [XXX]). From the outset, the vehicle suffered from recurring mechanical failures. It required service visits on August 10, 2023; March 25, 2024; July 26, 2024; September 20, 2024; and October 7, 2024. The final incident on [XXX], involved a fuel pump failure that caused the vehicle to stall in traffic, placing me in a terrifying situation where another driver, enraged and armed, threatened me while I waited for a tow truck. Mercedes-Benz acknowledged the vehicle was inoperable and issued a replacement lease on October 15, 2024 VIN [XXX]. However, this second vehicle also proved defective. Within two weeks, it was back in the shop for service. Since then, it has required repairs on December 24, December 31, 2024, and again on May 28, 2025, including another engine stall that posed a serious road safety threat. Despite my good faith efforts to resolve the matter, Mercedes-Benz, via their claims processor Sedgwick, is attempting to charge me $12,873.52 in negative equity, in addition to fees for Prepaid Maintenance and 4N1 Assurance Protection, as part of their settlement offer. These charges are both inappropriate and unlawful under the principles of lemon law and consumer protection. Request for Relief: •Immediate release from the lease agreement without penalty. •Refund of all payments made toward both defective vehicles. •Full waiver of any negative equity or ancillary product charges. •Any civil penalties deemed appropriate by your office against Mercedes-Benz USA and/or Sedgwick. I have already filed a complaint with the NHTSA (ID Number: 11665555) As I feel as though my safety is in imminent danger driving this vehicle.

Mercedes-Benz acknowledged the vehicle was inoperable and issued a replacement lease on October 15, 2024 VIN [XXX]. However, this second vehicle also proved defective. Within two weeks, it was back in the shop for service. Since then, it has required repairs on December 24, December 31, 2024, and again on May 28, 2025, including another engine stall that posed a serious road safety threat. Despite my good faith efforts to resolve the matter, Mercedes-Benz, via their claims processor Sedgwick, is attempting to charge me $12,873.52 in negative equity, in addition to fees for Prepaid Maintenance and 4N1 Assurance Protection, as part of their settlement offer. These charges are both inappropriate and unlawful under the principles of lemon law and consumer protection. Request for Relief: •Immediate release from the lease agreement without penalty. •Refund of all payments made toward both defective vehicles. •Full waiver of any negative equity or ancillary product charges. •Any civil penalties deemed appropriate by your office against Mercedes-Benz USA and/or Sedgwick. I have already filed a complaint with the NHTSA (ID Number: 11665555) As I feel as though my safety is in imminent danger driving this vehicle.
