2022 MERCEDES-BENZ Gle 350 4MATIC

On July 7, 2026, my 2022 Mercedes-Benz GLE 350 experienced a serious engine malfunction. After stopping at a traffic light, the engine began shaking violently and idling roughly. When the traffic light turned green, the vehicle accelerated extremely slowly and had very little power, making it difficult to clear the intersection. The engine continued running roughly, and I was concerned the vehicle could stall in active traffic. At the same time, the ECO start/stop system automatically disabled itself and displayed "OFF" in white on the instrument cluster. Because the vehicle appeared unsafe to drive, I had the vehicle towed to Mercedes-Benz of San Jose on July 8, 2026. The dealer confirmed the rough-running engine condition and advised that the cylinder head ("engine top") must be replaced. This incident occurred after three repair attempts for recurring engine-related check engine light faults within approximately six months: 1.January 23–28, 2026: Check engine light illuminated. Dealer diagnosed fault in motor electronics for code P240200 (Actuation of the pump in the diagnostic module of the evaporative emission control system has a short circuit to positive). Separated diagnostic module from charcoal canister. Replaced. Cleared codes. System OK. 2.May 13–26, 2026: Check engine light illuminated again. Dealer diagnosed fault code P260F00 (monitoring of the evaporative emission control system has a malfunction). Multiple diagnostic tests were performed. All OK. Evap system OK. No replacements of parts before the vehicle was released. 3.July 4, 2026: Check engine light illuminated for a third time. On July 7, the engine began running extremely rough while stopped at a traffic light, causing a significant loss of power and severely limited acceleration. The vehicle was subsequently towed to the dealership. I am submitting this report because the recurring engine malfunction has progressed to a sudden loss of power in traffic, creating a potential safety hazard.

Incident 1- on several occasions the screen went blank on my dashboard where I could not see the odometer and important information. This has happened on several occasions and sometimes happen to wait until the next day in order for it to come back on Incident 2- car is now in the dealer for engine issues and rattling sound once started. Needs to restart before sound stops
