Some Mercedes-Benz ML320 owners report experiencing issues with an inoperative trunk that fails to open, often due to trunk latch problems that prevent proper latching. These owners may notice visible issues with the trunk lid and latch, such as debris or misalignment, which can be identified through regular maintenance. Additionally, some have found that lubricating the latch mechanism with silicone spray can improve functionality if it is sticking. In cases where the trunk latch is unresponsive, utilizing the manual release option may be necessary, which involves locating a lever on the passenger side. If these troubleshooting steps do not resolve the issue, some owners consider replacing the tailgate latch as a more permanent solution to persistent problems with the trunk mechanism.
