2016 Mercedes-Benz GLE 350 Problems

While driving my 2016 Mercedes-Benz GLE 350, the vehicle suddenly shut off and lost propulsion without warning. There was no check-engine light or other warning before the failure. The engine would crank afterward but would not restart, leaving the vehicle disabled. The vehicle has an open NHTSA safety recall (22V-955) involving the fuel pump control unit and potential loss of propulsion. The vehicle is currently at Benzel-Busch Mercedes-Benz for recall inspection and diagnosis. I am reporting this because the sudden loss of propulsion while driving created a serious safety risk.

The contact owns a 2016 Mercedes-Benz GLE350. The contact stated that while opening the door, a cracked fuel injector was spraying gasoline. When the door handle was pulled, an aftermarket module ignited the fuel, causing an explosion and heavy smoke from the engine compartment. The contact stated that the vehicle had been taken to the dealer previously for the same issue, but the dealer dismissed the information and returned the vehicle. Shortly afterwards, the failure reoccurred and was recorded. The vehicle had been at the dealer for two months, and the dealer blamed the failure on an aftermarket part, even though the dealer had installed the parts. The vehicle was driven to the dealer, where it was diagnosed with fuel injector failure and was associated with the aftermarket parts that were installed by the dealer. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 133,000.

The contact owns a 2016 Mercedes-Benz GLE350. The contact stated while driving at an undisclosed speed, the vehicle shuddered and hesitated while accelerating and depressing the accelerator pedal. The check engine warning light was illuminated. The vehicle was taken to a local dealer where it was scanned, and the dealer retrieved DTC code: P04200. The contact was informed that the passenger side catalytic converter had failed, causing the Oxygen sensor to run lean. The contact stated that upon further investigation, the failure was linked to Emission Service Campaign: 2022080005; however, the VIN was not included. The manufacturer was notified of the failure and referred the contact to the NHTSA Hotline for assistance. The failure mileage was approximately 90,000.

On 8/28/2026, my Mercedes-Benz GLE 350 (W166, M276 engine) experienced a sudden, catastrophic engine stall while driving in active traffic. There was no Check Engine Light (CEL), dashboard warning, or mechanical hesitation prior to the failure. The vehicle instantly lost all propulsion, power steering, and power braking assist, creating an extreme crash hazard and requiring immense physical effort to maneuver the dead vehicle off the roadway. Independent diagnostic teardown by a module specialist confirmed the root cause: an unrepairable internal short circuit between the internal PCB layers of the Engine Control Unit (ECU). Because Mercedes-Benz chose to mount this sensitive electronic module directly to the top of the hot engine block, it is subjected to extreme thermal cycling and vibration. This predictable thermal degradation causes the internal board layers to delaminate and short out. When this internal short occurs, the ECU instantly dies and shuts down the entire vehicle without warning. This is a severe, life-threatening engineering defect. A safety investigation is urgently needed to address the mounting location and thermal failure rate of M276 ECUs before a sudden high-speed stall results in a fatal collision.

The door hinges are an issue with these cars many many people are expressing the same issues which is the door hinges fail and start popping and cracking. Mercedes isn’t issuing a recall or remedy for this. Also there’s an issue with the passenger airbag weight sensors going bad which is throwing the airbag light off (which this is also happening in my car) the service center I talked to knew about this is agreed it a issue they see time and time again with these cars. Mercedes needs to make this right.
