Emissions
Emission Recall: Mack Trucks has determined that certain vehicles equipped with a model year (“MY”) 2017-2018 MP8 VGT engines may not meet California and Federal Regulations (CARB). This Recall is for updated software that will reduce the amount of time necessary for the system to operate in a cold engine warm-up strategy and provide health monitoring of the Selective Catalyst Reduction (SCR).

Emissions
Emission Recall: Mack Trucks has identified that the Selective Catalyst Reduction (SCR) system in certain vehicles equipped with the MY 2017 or 2018 MP8 (13L VGT) engine are not meeting California and EPA emissions standards, or Mack cannot confirm its compliance. These vehicles have been flagged due to telematics data showing that the NOx conversion efficiency of the SCR system has dropped below 94% for eight weeks. Alternatively, these vehicles may have communication issues with telematics, such as not reporting or ceasing reporting for the same period.
