In my case, the vehicle began showing the following symptoms: Rough engine idle and noticeable vibration during startup Loss of power, especially when accelerating Check engine light with fault codes related to misfire or combustion issues Oil and/or coolant loss, with no external leaks Engine knocking or ticking noises near the top end of the engine After a professional inspection and diagnostic testing, I was informed that the issue is likely due to a defect or failure in the cylinder head, possibly involving warping, cracking, or failure of the valve seats or head gasket area. Upon further research, I discovered that this issue is not isolated. Multiple owners of vehicles with the M264 engine\u2014including various GLE, C-Class, and E-Class models\u2014have reported similar problems, often occurring well before 70,000 miles and despite regular maintenance. The pattern suggests a possible design flaw or quality issue with the engine\u2019s cylinder head. As of now, it appears no formal recall or technical bulletin has been issued by Mercedes-Benz regarding this specific problem. However, the number of similar reports suggests the issue is widespread enough to merit formal investigation or at least acknowledgment by the manufacturer.","products":[{"type":"Vehicle","productYear":"2021","productMake":"MERCEDES-BENZ","productModel":"GLE 350","manufacturer":"Mercedes-Benz USA, LLC"}]}]}
