Problem overview

Some Mercedes-Benz ML320 owners report experiencing trunk latch malfunctions due to rust, which can prevent the trunk from opening with either the remote or manually. This issue is often caused by rust near the handle or latch area, which can impede the latch's proper functioning despite being in a location typically protected from rain. While this malfunction may be concerning, it is considered a low priority compared to more critical issues such as ABS lights, indicating it may not pose an immediate safety risk. To address this problem, owners are advised to inspect the latch area for rust buildup, repair or replace damaged components as needed, and perform regular maintenance checks on trunk components to ensure proper functionality.
