“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. …”
NHTSA complaint #11751934, filed 2026-07“The infotainment and instrument panel screens blacked out after the vehicle was started a few miles away from our home. I was unable to see the speedometer while driving back home. This was the first time that this has happened to us. After a Google search of Mercedes Benz 2025 GLC 300, this event appears to be fairly common.”
NHTSA complaint #11694886, filed 2025-10“I am writing to formally express my deep dissatisfaction and serious concerns regarding both my 2024 and 2025 Mercedes-Benz vehicles, purchased/leased through your dealership. I am now facing an unacceptable situation that not only violates my consumer rights but has repeatedly placed my personal safety in jeopardy. After significant issues with my original 2024 vehicle, I was provided a replacement, which I took delivery of on October 15, 2024. Unfortunately, within two weeks, the replacement vehicle was already back in the shop for repairs. …”
NHTSA complaint #11665555, filed 2025-06“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. …”
NHTSA complaint #11737239, filed 2026-05“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. …”
