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.

Information screens; speed, gear etc. and middle screen, radio, gps, etc, go blank. Screens are black with no information. There’s also a popping sound happening in the background over the speakers. You can start the car and put it in gear and drive - but with no information in either computer screens. Safety issue for sure! After waiting approximately 3 hours, the 2 screens come on when car is started.

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.

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
