Example complaints

Engine: “My 2023 Mercedes-Benz GLB 250 is experiencing engine misfires and fault codes consistent with a known cylinder head defect that is the subject of a recall affecting 2022 and earlier models. A certified mechanic has confirmed the issue aligns with the recall defect. Despite identical symptoms and engine configuration, my VIN is excluded. The condition results in loss of power and creates a potential safety hazard while driving. …”

NHTSA complaint #11733918, filed 2026-04

Other or unknown: “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.”
