2020: “Four weeks ago I turned on my car and saw a warning light that said leftside curtain airbag malfunction . I immediately called the mercedes 800 number and they transferred me to my local service center. I took it in and the guy was super nice, they provided me with a loaner and he said he would call me when the work was complete. He called me that evening and told me that my car was ready. I picked it up the next morning and the warning light was gone. Yes! Flashforward three weeks and the warning light came on again. …”

2021: “Family and I were driving on the interstate and heard a loud bang (like a shotgun) followed by immediate glass everywhere. The panoramic sunroof exploded. We had to drive 4 hours like this - lucky we didn’t jerk the wheel on the interstate with the noise. Absolutely sickening that this is so prevalent and Mercedes won’t do anything about it.”

2023: “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. …”
