What's wrong?
The electric powertrain control unit on the 2021-2022 220 and K270 trucks is the software-managed controller for the battery electric drive system. It also needs to accept stability control commands when the truck is slowing through regenerative braking, which uses the electric drive system to help slow the vehicle and recover energy.
On affected trucks, the control unit software was not programmed correctly to accept certain stability control commands during regenerative braking. The stability control supplier found that commands were sent but not carried out by the electric powertrain control unit. That means a stability-control intervention can be missed during that braking mode until the software is updated.
There is no warning sign before failure. The issue is in the control unit software, so the driver does not get a reliable advance cue that a stability control command was ignored.
Who's affected?
Covers two medium-duty truck models from the 2021 and 2022 model years, both tied to the same automatic-transmission control software.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
If the power train control unit fails to process stability control commands, the truck can lose intended stability-control assistance, which increases crash risk. There is no warning sign before failure, so schedule the software update soon. Repair is free at any franchised Peterbilt dealer.
What should I do?
- Check your VIN to confirm your 2021-2022 Peterbilt 220 or K270 is included in this recall.
- Contact a franchised Peterbilt dealer to schedule the free electric power train control unit software update that restores stability-control command processing during regenerative braking.
- Bring the recall notice if you received one, and reference recall number 22V630 when you call.
- Drive with extra space until the repair is confirmed complete, since the software issue affects stability-control command processing during regenerative braking.
What happens at the repair
At the dealer, a Peterbilt technician updates the electric power train control unit software so it processes stability control commands while the vehicle is in regenerative braking mode. The update is free under the recall, and the filing says all vehicles were remedied in October. Owners who paid for this repair before the recall notice arrived can seek reimbursement through the manufacturer's standard reimbursement plan. Bring documentation for the prior repair to the service desk or contact customer service.
