What's wrong?
The affected 2017 Peterbilt trucks use a Cummins ISX12 or ISX15 engine with an engine control module, or ECM. The ECM is the computer that manages key engine functions and keeps the engine running as conditions change. It reads signals from the truck and sends commands to engine systems.
In this recall, the ECM can develop an internal short circuit. A short circuit means electrical current moves through the module in the wrong path, which can shut down the engine controls. If that happens while the truck is being driven, the engine can stall and then fail to restart.
There is no warning sign before failure. The recall filing says the stall can happen without warning, so an owner does not get a dashboard symptom or drivability change that reliably points to the ECM before it quits.

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?
An engine stall without warning increases the risk of a crash because the truck loses power while moving. If the engine quits, steer to a safe location, stop the truck, and call the dealer before driving again. Repair will be free at any franchised Peterbilt dealer once available.
What should I do?
- Check your VIN to confirm your 2017 Peterbilt 367, 579, 567, T660, 320, 389, 587, 365, C500, T680, T800, T880, or W900 is included in this recall.
- Contact a franchised Peterbilt dealer and ask for the current repair status for recall number 16V426.
- Ask whether the free engine control module replacement is open for your truck; the repair fixes the short-circuit condition that can stall the engine without warning.
- Bring the recall notice if you have it, and give the dealer recall number 16V426 when you call or arrive.
- Drive cautiously until the repair is complete. Leave extra following distance and pull over safely if the engine begins to lose power.
What happens at the repair
Because the remedy is listed as under development, do not assume the final repair can be scheduled yet. Once it opens, a Peterbilt technician will replace the defective engine control module with a corrected unit. The final dealer repair will be free once available, with parts and labor covered by the recall. Cummins is administering owner notices and the repair program, so the dealer can confirm the correct handling path for your VIN.
