Brand-wide AION Problem Patterns
Screen-first cockpit software: important functions (mirrors, drive modes, regen, ADAS settings) sit behind long menus with patchy English translation, and the shortcut bar disappears under phone mirroring — the single most repeated UK criticism of both the V and UT.
Over-eager driver aids: driver-monitoring and speed-limit chimes that nag from the first mile, safety systems that re-enable at every restart, and a UT adaptive cruise that Carwow found braking for cars that are not there.
Chassis calibration rather than hardware: busy, shuddery low-speed ride over sharp bumps, grabby stoppers at parking speeds, and a front axle that spins up eagerly off the mark — no mass component failures reported yet, and no DVSA recalls as at October 2026.
Ownership logistics: a brand with only ~15 UK dealers when it launched, real-world range 10–20% below WLTP, and zero long-term reliability history; the eight-year servicing/warranty package is the main mitigation when checking a used example.
