Isuzu Trucks Problems
  • Older models need retrofits and engine upgrades.
  • NPRs have some emission and regen problems. Trucks can break down after long hauls.
  • NPRs 2009 used for sweeping have issues with the DPF. The chassis dies while being used, with no warning. It seems that sweepers don't move with enough speed to keep the DPF system functional. Problems persist even after manul regenerations and periodic cleaning.
  • In an NQR crew cab model with less than 5000 miles on it, the cruise control shut off and the display showed a red exhaust system light. The truck was regularly regenerating without any problems and had plenty of DEF fluid.
