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.

By System
The 2022 Mercedes-Benz E 450 has 5 recalls, the most serious being a fire risk from a 48-volt ground cable in the engine compartment that can overheat if its connection was not properly tightened at the factory.
The fuel pump on certain vehicles can shut down without warning while driving, cutting power to the wheels mid-travel and raising the risk of a collision. This issue was filed across multiple model years and configurations, but the consequence is the same: the engine loses drive power and the vehicle may coast to a stop in traffic.
Two electrical recalls affect driver assistance and crash response features. On vehicles equipped with a heated leather steering wheel, a software condition can disable the hands-off detection function, which means the driver assistance system will not warn the driver to grip the wheel and the vehicle will not automatically call emergency services or bring itself to a safe stop if the driver becomes unresponsive. Separately, a backup battery issue can leave the vehicle unable to activate its automatic emergency call system, hazard lights, powered seats, or automatic door locks in a crash, all of which can affect occupant safety and rescue response when they are needed most.
