The contact stated that while his daughter was sitting in the rear driver's side seat and attempting to exit the vehicle, the speaker on the rear driver's door scraped her right elbow. The contact stated that the screw holes for the speaker had jaggedly sharp edges, and the holes on the speakers looked like perforations on a grater. The contact stated that the other shiny metal door speakers on each door were also sharp and posed a potential injury risk. The vehicle was taken to a dealer.

On Thursday, August 20th at approxmately 5:30PM my 2026 Mercedes Benz suffered a catastrophic transfer case failure and driveshhaft failure at highways speeds, causing a complete loss of propulsion. Putting me in immediate danger of on coming traffic. After the got to the shoulder I waited about 3 plus hours in pouring rain waiting for Mercedes Benz roadside assistance. The safety of this vehicle put me, my wife and family in immediate danger if this happens again. I do have a video I cannot upload as is is too large, but have loaded an image of the car in service showing transfer case. Please let me know how i can share the video.

Reading this record

No unusual pattern of severe incidents in the complaint record.

Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.

Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
