What's wrong?
The low air pressure warning software on affected 2020-2024 Autocar Legend vehicles watches the air brake system for pressure that has dropped too low. Air brakes depend on stored air pressure to apply braking force, and the warning is supposed to alert the driver before that pressure falls past the required point.
On these vehicles, the software was set to activate the low air pressure warning at 59.1 psi instead of the required 60 psi. That is a software setting problem, not a broken brake chamber or damaged air line. The result is that the warning comes on later than required, so the vehicle does not meet the air brake warning standard.
There is no warning sign before failure. Owners should not expect a separate sound, light, or pedal change that tells them this software setting is wrong before the low air pressure warning misses the required activation point.

What's the safety risk?
If the low air pressure warning software fails, the driver can keep driving without functioning brakes, which increases crash risk. There is no warning sign listed before failure, so treat any brake or air-pressure concern as a reason to stop and call the dealer. Repair is free at any franchised Autocar dealer.
