# Detroit DD13: Repair Costs, Recalls & CARB Status | Big Rig Risk

> Detroit DD13 specs, one-box aftertreatment repair costs, DD13-named NHTSA fuel-pump recalls, and why this 2010+ engine is the California-legal choice.

**Verdict:** inspect

A 2010+ engine that "complies with EPA, CARB emissions, GHG, and OBD requirements" — the clean California-legal contrast to a pre-2010 Cat C15 or Series 60. Watch the shared Detroit one-box aftertreatment (ACM $1,800–$2,400, one-box $4,000–$6,000 on the DD15 sibling) and confirmed DD13-named Bosch fuel-pump / fuel-line recalls.

**Documented failure risks:**
- One-box aftertreatment (ACM / DPF-SCR): Sibling-platform (DD15) evidence: ACM failures $1,800–$2,400 and one-box aftertreatment system issues $4,000–$6,000. The DD13 shares this one-box architecture — inspect aftertreatment fault history and regen behavior. Labeled sibling-platform, not DD13-confirmed.
- Turbocharger: Sibling-platform (DD15): turbocharger problems $2,200–$3,200. Check for boost faults and shaft play.
- Bosch high-pressure fuel pump / fuel line (2006–2012 builds): DD13-specific per NHTSA: the Bosch high-pressure fuel pump element may crack (hydrogen-induced stress corrosion) and the pump-to-rail high-pressure fuel line may crack — both causing a fuel leak. Verify the VIN against the recall campaigns and confirm the remedy was performed.

**Recall:** NHTSA 11V287000 / 10V339000 (FUEL PUMP): DD13/DD15 Bosch high-pressure fuel pump crack — fuel leak
