This page covers 5 recalls and 11 owner complaints for the 2022 Mercedes-Benz E 450.
Complaints for the 2022 Mercedes-Benz E 450 are spread across a handful of systems with no single dominant pattern, given the small complaint set. Brakes, the electrical system, and the fuel/gasoline system each draw two reports. On the electrical side, owners describe a 48-volt battery malfunction warning appearing on the dashboard, followed by a red warning light and a rapid loss of power that forces them to pull over within roughly 30 seconds. An underbody splash shield detaching at highway speed and dragging on the road surfaces in multiple reports, creating significant noise and prompting concern about a tire failure. A separate recurring complaint involves low-profile OEM tires developing sidewall bubbling when the steering is turned to full lock at low speeds, such as while exiting a parking space.
