What 25 owners told NHTSA about the 2024 Mercedes-benz E-class Cabrio

On a recent drive, my 2024 Mercedes-Benz E350 VIN: [XXX] suffered a catastrophic safety hazard involving a complete loss of drive power and sudden engine shutdown while operating at highway speeds. I had to navigate across active highway lanes with no engine propulsion to reach safety. ​Simultaneously, the vehicle experienced a widespread failure of its master interior electrical grid. The driver's power seat became permanently frozen in a fully reclined position while driving, creating an immediate driver-ergonomic safety hazard. Multiple interior USB charging ports and the passenger-side power seat also lost power entirely. ​This combination of engine stalling and localized interior electronic failure strongly aligns with NHTSA Recall 24V-115, which involves faulty 80-Amp fuses in the main fuse box causing a loss of propulsion. The vehicle also currently displays an open, unresolved safety recall for its airbag systems. The manufacturer's dealership is attempting to charge multiple diagnostic fees to investigate these interconnected issues rather than processing them under an active safety campaign. I am filing this report to document a severe, active propulsion failure in the field that represents an immediate threat to life and highway safety.

My vehicle is not included in the current high voltage battery recall under NHTSA recall 26V073, as it has a manufacture date of 08/2024 per door jamb sticker, however, page 5 of the NHTSA report explicitly states “A change in the production procedure of our supplier ensures that this issue can no longer occur on vehicles produced from July 31, 2024 onwards.” This leaves car production between May and July 31 (and likely beyond!) unaccounted for in the recall. My car was built in August 2024, likely with a battery manufactured prior to July 31, 2024 with the defect. I believe my car should be included in the recall/affected vehicles given its production date and the date of production remedy.
