Vehicle: 2023 Mercedes-Benz GLE 350 4MATIC Approximate mileage at failure: 75,000+ miles While driving my 2023 Mercedes-Benz GLE 350 4MATIC, the check-engine light illuminated and the engine subsequently began making a knocking noise. The vehicle remained operable and I drove it home. Because the event occurred on a Saturday, I drove the vehicle directly to an authorized Mercedes-Benz dealership the next business day. The dealership inspected the vehicle and documented metal flakes and pieces in the oil filter/filter housing, with suspected crankshaft/rod-bearing failure and possible additional internal engine damage. Mercedes-Benz recommended complete engine replacement. This vehicle had a prior documented check-engine-light event in April 2025. An authorized Mercedes-Benz dealership recorded diagnostic trouble code P03040085, indicating a cylinder 4 misfire. There were also previous check-engine-light concerns for which the underlying cause was not definitively identified. Mercedes-Benz subsequently issued an extended warranty applicable to certain M264-engine vehicles, including qualifying GLE 350 models, concerning cylinder-head/exhaust-valve wear associated with misfire fault-code families including P030x85. I am concerned that my vehicle may have experienced a developing M264 engine defect prior to the catastrophic internal engine failure and that sudden internal engine failure of this type could create a safety risk if it occurs while a vehicle is being driven at highw

Reading this record
No unusual pattern of severe incidents in the complaint record.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Most recent recall on file: none. Source: NHTSA Office of Defects Investigation.
