What's wrong?
The neutral start interlock on a 2011-2014 Kenworth T440 with an Allison transmission is part of the starting circuit. Its job is to let the engine crank only when the transmission is in neutral, so the truck does not start while a drive range is selected. It works through wiring between the engine harness, transmission controls, and vehicle software.
On affected T440 trucks, the engine harness was installed incorrectly on vehicles equipped with Cummins Westport ISL-G engines and NAMUX2 software. That wiring error leaves the neutral start interlock inoperable. When the interlock is not working, the starter circuit no longer has the intended check that confirms the transmission is in neutral before the engine starts.
There is no warning sign before failure. The defect is in the wiring and start-interlock logic, so an owner is not told by a sound, smell, or pedal change that the protection is missing.
Who's affected?
Covers the T440 across the 2011, 2012, 2013, and 2014 model years, all tied to the automatic transmission park/neutral start interlock switch.

Not every 2011-2014 Kenworth T440 truck is on the list. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
An incorrectly connected engine harness can let the T440 start while the transmission is in gear. That can make the truck move unexpectedly at startup and increase the risk of a crash. Confirm your VIN, use extra care when starting the truck, and schedule dealer inspection. Repair will be free at any franchised Kenworth dealer once available.
What should I do?
- Check your VIN to confirm your 2011-2014 Kenworth T440 is included in this recall.
- Contact a franchised Kenworth dealer to ask about the free engine-harness inspection and connection correction.
- Schedule the harness repair that restores the neutral-start interlock so the truck cannot start while the transmission is in gear.
- Bring the recall notice if Kenworth mailed one. If not, reference recall number 14V008 and Kenworth recall 14KWA when you call.
- Confirm the truck is in neutral before starting it until the harness connection is inspected and corrected.
What happens at the repair
The remedy record does not list the final repair as available yet. Once the dealer repair is available, a Kenworth technician will inspect the engine harness connection tied to the neutral start interlock. If the connection was installed incorrectly, the technician will correct the harness connection so the interlock works as intended. The dealer repair will be free under the recall, with parts and labor covered. Ask the Kenworth service desk to confirm the repair status before arranging service.
