MERCEDES-BENZ C 300 2023 VISIBILITY/WIPER
medium
When going into Reverse the passenger side mirror angles down to see curbs. When putting back into Drive it should be going back up to normal angle, but 20% of the time it does not go back up. If you're driving in the dark you may not know it's reverted back up and get into a car accident. Dealership said there are no issues and a technician stated it goes back up at +9 mph. I've gone over 30 mph driving on public street only to realize it late. I am hoping this gets publicity before an accident occurs due to a defective safety-comfort feature.

MERCEDES-BENZ SPRINTER 2500 2023 UNKNOWN OR OTHER
medium
2023 Sprinter van jack was pulled out for the first time to be used last week and found to be unsafe. The jack base is crowned in center, the edges flare upwards and large gouge/groove in metal base, causing the jack to noticeably wobble and rock in manner that it is unsafe to use, fear of jack tilting and dropping van onto user of jack. Jack base has obvious defects and unsafe to use. Have contacted dealer and referred to MBUSA who provided a case # and no resolution to provide a safe jack to replace the defective jack.

MERCEDES-BENZ SPRINTER 2500 2023 UNKNOWN OR OTHER

In August 2025, I had taken the van for a drive to charge things up, got home, put it in park and parked it in my driveway, which has a mild slope. ~ 30 seconds - 1 minute after me leaving the vehicle, it rolled backward out of the driveway, across a busy street and 1/4 into my neighbors yard. I was mortified, there is usually a lot of people walking their dogs, kids etc...and cars going by. The vehicle was stopped by the curb vs the 2nd back tire (Thie first one cleared the curb and was in my neighbors lawn. It ALMOST hit a BIG tree. I pulled it back into the driveway & checked it again, worried I may have somehow not put it in park, but it did it over and over again. Shortly after I put it in park and turned it off it "released" and started rolling spontaneously. I could have run over my neighbors; people, babies...pets, me... I piled logs and big rocks behind all 4 tires (put it park with the parking brake on of course,) & called the Mercedes dealer & made an appointment. I did not drive it again until it was "repaired," except for the fact that nothing showed up on the scanned as wrong. They kept if for 3 weeks but "it never did it again," & they "never found anything." They charged up the battery and said maybe it was because the battery got too low and that the chassis battery charges the transmission battery and maybe the transmission battery was low. They mentioned that they had had one other person come with the same problem. The local Winnebago dealership mentioned that they had had someone come in with the same complaint. With the vehicle unchanged after this potentially catastrophic event, how can I trust it? What happens if I am in it and it is parked on a slope and it does it again? What could happen if the transmission fails on the road? It was VERY SCARY. For a couple months I had a mini panic attack every time a young family walked by...what could have happened if they happened to be walking by when that happened. I will have to collect the info

My panoramic sunroof spontaneously exploded while driving down the highway, no external impact was made. The glass exploded from the inside out. It made a loud boom, it startled me on the highway resulted me to swerving on the road, which would have put me and other drivers at risk. There's plenty other MB drivers reported similar issues that stated. MB has also settled a class action lawsuit regarding such manner. UNKNOWN There were no warning signs prior to the event. The event spontaneous and sudden.
