Are there any known factory defects in the Changan Alsvin’s EVAP system o r purge valve reported by Pakistani users?

Some drivers believe the purge control valve failure is a design flaw. Is there a pattern of early failures across different Alsvin models?

While no official recall exists, there is consistent anecdotal evidence from owners and mechanics about:

Early purge valve failure in models from 2021–2022

Solenoid valves jamming o r sticking intermittently

Loose o r brittle EVAP hoses, especially near the intake manifold

These issues suggest a component quality issue o r poor compatibility with Pakistan’s harsh driving and climate conditions.
