Navistar recalls trucks; engine rev may overcome parking brake

Lisle, IL – February 1, 2021 –Navistar International (NYSE:NAV) has recalled 17,213 medium- and extreme-duty trucks that may rev while parked and overcome the parking brake. The affected component is engine electronic control module (ECM) calibration software. ECM controls over 100 elements in the truck and is responsible for its smooth operation.

The  recall includes the following Navistar International models:

  • 2014-2020 International Durastar
  • 2020-2021 International HV
  • 2019-2021 International MV
  • 2015-2018 International Workstar

Recall summary  

The trucks in question are equipped with a Power Take Off (PTO) switch that transmits the power of the engine to truck’s accessories such as a dump truck’s bed, water pumps or a garbage truck compactor. PTO is in most cases directly connected to the ECM. 

Due to a programming error, the recalled Navistar International trucks’ may rev strongly enough to overpower the parking brake, while the truck is in drive or reverse. This may cause it to move unexpectedly.


The International truck, which can weigh up to 36.5 tons, could hit people or things in its path and poses a safety risk to the driver and people nearby.  This is especially dangerous if the truck in question has one of the accessories engaged. Imagine a dump truck moving away with its bed raised or a garbage compactor rolling with the compactor up!

In addition to physical damage to people and property, moving with the PTO switch engaged may harm the motor.

The repair

Navistar International will install an update on vehicles’ Cummins ECMs with a neutral interlock that will keep the vehicle in neutral as long as the PTO is switched on. Navistar plans to send recall notification letters to owners on February 19. More information about the recall and possible reimbursement for repairs will be included in the letter.
