PACCAR / MX or Cummins ISX Engines

If you own, or owned, a PACCAR truck (e.g., Peterbilt, Kenworth) with an MX engine, or a truck with a Cummins ISX engine, then you may have a legal claim against PACCAR and/or Cummins. Quantum Legal has filed a putative class action lawsuit against each company related to defects in and misrepresentations about the emission systems on these engines. The problems with the emission systems are systematic and deprive owners/operators a fully functioning engine often resulting in numerous trips to the repair shop and engine shutdowns or significant decreases in performance.
