Haval Jolion Software Update Verified [upd] May 2026

The Haval Jolion has received several verified software updates across various global markets, primarily focused on improving its Advanced Driver Assistance Systems (ADAS) and infotainment connectivity. While many owners report that updates must be performed at a dealership rather than Over-the-Air (OTA), recent patches have addressed critical performance and usability issues.
