From the research record

  • FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): EGR cooler: "Internal EGR cooler crack or tube erosion (very common on MP7/MP8 around 400K-700K miles)" https://carcodefinder.com/diesel/codes/volvo-mack-mp8-egr-cooler-coolant-leak/
  • FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): injector cups: "Copper injector cups seal the injectors to the head. Many start leaking between 300,000 and 600,000 miles, pushing fuel into coolant and air into the fuel rail." https://www.cherishyourcar.com/mack-mp8-engine-problems/
  • FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): camshaft: "Pressed cam lobes can spin on the hollow shaft on higher-mileage units, usually past 400,000 miles." https://www.cherishyourcar.com/mack-mp8-engine-problems/
  • FAILURE (2026-09-05, agent-fetched, Claude spot-verified sample): aftertreatment / 5 MPH derate: "See an SCR efficiency code like SPN 4364 FMI 18. If readings stay out of range, it limits power. Finally a 5 MPH derate under SPN 5246 FMI 0." https://www.cherishyourcar.com/mack-mp8-engine-problems/
  • MARKET (7 listings observed 2026-09-05): low $95,000 / median $95,000 / high $144,900. Agent-sourced: 6 of 7 real listings are $95,000 from one dealer (Vanguard Truck Center-Tolleson, 2018-2019, 209k-225k mi -- a fleet lot, not diverse market sampling), plus one differentiated 2021/138k-mi unit at $144,900. Real, current asking prices; low diversity flagged for transparency.
