What owners report

“I purchased a used Mercedes-Benz from Freehold Mitsubishi in early 2024. Within hours, serious safety issues appeared, including a check engine light, cylinder misfire, EVAP leak, traction control failure, and blind spot assist malfunction.”

An owner's complaint to NHTSA about the engine, Jun 2025

“ML350 engine stalled while driving on an expressway and would not turn back on. ML350 needed to be towed where it was determined that water accumulated in the spare tire wheel well, leading to the fuel pump short circuiting. This is directly related to NHTSA campaign 22V955000. That recall repair was completed prior to this incident.”
