Recall 20V810 affects 17,213 2014-2021 International Mv, Durastar, Workstar, and Hv trucks for faulty PTO software. Free ECM update at any franchised International dealer.
International is recalling 17,213 2014-2021 Mv, Durastar, Workstar, and Hv vehicles under recall 20V810 because the engine can rev when the parking brake is set, the transmission remains in drive or reverse, and the stationary PTO switch is engaged. Unexpected movement can increase the risk of a crash or injury, and International dealers will complete the free repair.

What's wrong?
The ECM, the engine computer on affected 2014-2021 International Mv, Durastar, Workstar and Hv vehicles, controls engine speed and stores calibration settings for the power take-off system. The power take-off control lets a stationary truck run equipment from engine power while parked, and its neutral interlock is supposed to keep engine-speed control from raising rpm unless the transmission is in neutral.
On these vehicles, the calibration for feature code 12VXT or 12VXU did not have the PTO neutral interlock enabled. If the parking brake is applied while the automatic transmission remains in drive or reverse, engaging the stationary PTO switch lets the engine rev. That extra engine force is enough to overcome the parking brake and move the vehicle.
There is no warning sign before failure. The condition appears when the parking brake is set, the transmission is still in gear, and the operator engages the stationary PTO switch.
Who's affected?
Spans Mv, Durastar, Workstar, and Hv trucks from 2014 through 2021, all tied to the same ECM calibration software.

The year and model narrow the scope, but the VIN decides. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
Unexpected vehicle movement can increase the risk of a crash or injury. There is no warning sign before the problem happens, so confirm your VIN and schedule the dealer update soon. Repair is free at any franchised International dealer.
What should I do?
- Check your VIN to confirm your 2014-2021 International Mv, Durastar, Workstar, or Hv is included in this recall.
- Contact a franchised International dealer to schedule the free Cummins ECM software update that enables the PTO neutral interlock.
- Bring the recall notice if International has mailed one. If not, reference recall number 20V810 when you call.
- Avoid stationary PTO operation with the transmission in drive or reverse and the parking brake set until the software update is complete.
What happens at the repair
At the dealer, an International technician updates the parameters in the Cummins ECM for feature codes 12VXT or 12VXU. The update enables the PTO neutral interlock so the stationary PTO cannot override the parking brake condition described in recall 20V810. The software update, parts, and labor are free under the recall. If you already paid out of pocket for a related PTO neutral interlock or ECM parameter repair before the owner notice, International's standard reimbursement plan applies. Follow the reimbursement instructions in the owner notification and bring repair paperwork to the service desk.

Frequently asked questions
What is recall 20V810?
Recall 20V810 covers 17,213 2014-2021 International Mv, Durastar, Workstar, and Hv vehicles with Cummins ECM software settings tied to stationary PTO operation. Under the recalled condition, the engine can overcome the parking brake, creating unexpected movement and crash or injury risk.
What should I do if my 2014-2021 International Mv, Durastar, Workstar, or Hv is on this recall?
Check your VIN to confirm your specific vehicle is included in recall 20V810. If it is, contact a franchised International dealer to schedule the Cummins ECM parameter update. Reference recall 20V810 or International recall number 20510 when you call.
Is the recall repair free?
Yes. Federal recall law requires manufacturers to repair safety defects at no cost, and International dealers will update the Cummins ECM parameters free of charge. The dealer repair enables the PTO neutral interlock for the affected feature codes.
What is the safety risk?
The safety risk is unexpected vehicle movement. When the parking brake is applied, the transmission is still in drive or reverse, and the stationary PTO switch is engaged, the engine can rev enough to overcome the parking brake. That increases crash or injury risk.
What if I bought this International truck used?
The free recall repair still applies. Federal recall law follows the vehicle, not the first owner. Check your VIN, then call a franchised International dealer with recall 20V810 or International recall number 20510 so the service desk can confirm coverage.
