**Verdict:** insufficient-data

Documented failure points and real market prices for the International HX Series, sourced and dated.

**Observed used price:** $69,500–$99,900

**Documented failure risks:**
- EGR cooler (International A26 engine): EGR cooler cracking on the International A26 engine used in HX-series trucks lets coolant mix with exhaust gases.
- variable geometry turbo actuator: The A26's VGT actuator sticks or fails, cutting power and fuel economy on HX-series trucks running this engine.
- diesel particulate filter: DPF regeneration failures on the A26 occur when the truck doesn't reach operating temperature long enough for a full regen cycle, common in vocational duty cycles.
- fuel injectors: Water contamination in fuel causes costly injector failures on the A26 engine.
