Yes, many users have found that the locking mechanism of the Alsvin’s fuel cap is sensitive and prone to misalignment. The cap often requires precise alignment and pressure to lock correctly, and the lack of a firm click sometimes misleads owners into thinking it is secure when it is not. The threads may also wear prematurely, especially if over-tightened. This suggests a design flaw, although some of the issues may also stem from users being unaware of the correct technique for securing the cap. The design does not tolerate even minor deviations in positioning.
