What's wrong?
The electronic stability control system on these 2022-2023 T680 and 579 battery electric trucks is software that helps the truck stay stable during certain braking and handling events. It reads vehicle information, including estimated mass, then commands the stability-control system to react when the truck starts to lose stability. Heavy electric trucks depend on that calculation because weight affects how the truck responds.
On affected trucks, the supplier software reports the wrong parameter value. That error causes the program to underestimate the mass of the vehicle. With the truck weight calculated too low, the stability-control software is not calibrated to the actual load it is managing, so the truck does not meet the required heavy-truck stability-control standard.
There is no warning sign before failure. The issue is in the software logic, so the driver is not given a specific light, sound, or change in pedal feel before the incorrect stability-control calculation occurs.

The software update is free under the recall, with parts and labor covered. If you've already paid out of pocket for a related software repair before the recall notice, the manufacturer's general reimbursement plan covers documented expenses.
