Why does the fuel cap of Changan Karvaan often become loose o r cracked over time in Pakistani conditions?

In Pakistan’s extreme weather—scorching summers and dusty roads—plastic fuel caps can degrade, expand, o r crack. Many Karvaan owners report that even new vehicles develop fuel cap issues within months of use.

Pakistan’s harsh environment — with extreme heat, UV exposure, and dusty roads — puts extra stress on plastic components like the fuel cap. The material can become brittle, expand unevenly, o r wear out faster than expected. Many Karvaan owners report cap issues within a few months, especially if the van is parked in direct sunlight regularly.
