Caterpillar Trucks Problems
  • Customers complained that the Caterpillar exhaust emission control system used in C13 and C15 heavy-duty on-highway diesel engines is defective. The defect caused vehicles to shut down. A lawsuit started and was settled for $60M.
  • The system’s diesel particulate filter on Caterpillar trucks doesn’t always regenerate like it’s supposed to, leading to a complete shutdown of the engine.
