Graco Turn2Me car seat is loosening over time when installed with the vehicle seatbelt and the SnugLock Lock-Off. The vehicle seat belt was also switched to a locked mode after proper installation and did not make a difference over time. The car seat continues to loosen over time to the point where it is moving more than an inch side to side at the belt path. This can cause injury to a child during a crash. Car seat has been installed with the assistance of certified Child Passenger Safety Technicians and Instructors on multiple occasions.

Owner report 11733638 · 2026-04-24 (April 24, 2026)
Reporting because I see reports on other searches of this happening on other Mercedes Benz various years and models, the front stationary roof panel has shattered, cracked. I was lucky, my vehicle is only cracked (leaving my windshield components open to the weather , ie rain in Washington). Others report shattering while driving and having injuries from blowing glass. This appears to be an ongoing problem with Mercedes, they want over $2000 to fix a common problem with their vehicles.

Reported: 2026-07-24 (July 24, 2026)
Mercedes-Benz USA, LLC (MBUSA) is recalling certain 2020-2021 CLA, 2019-2022 A-Class, 2022-2023 C-Class, 2024 CLE, 2020-2026 GLA/GLB, and 2023-2024 GLC vehicles. Please refer to MBUSA's recall report for specific model information. The micro-switch in the driver's door lock may corrode and fail to detect an open door, preventing the electronic parking brake or "Auto-Park" feature from engaging automatically. This may result in a vehicle rollaway.
