I am submitting this complaint regarding serious and repeated electronic failures in my 2023 Mercedes-Benz E 450 that pose a significant safety risk to myself and other drivers on the road. The vehicle has experienced complete dashboard failures on multiple occasions, including the loss of speedometer, fuel gauge, and gear shift indicators. Most critically, the vehicle recently shut down while in motion, displaying a aœmalfunctiona warning and disabling the electronic steering system. I was unable to maneuver the vehicle off the road, creating an extremely dangerous situation. This vehicle has been brought to the dealership three or more times for the same issue, with no permanent resolution. I believe this constitutes a serious safety defect. I respectfully request that the NHTSA investigate this matter as a potential recall issue.
