What's wrong?
The ABS module on the 2020-2021 Ram Promaster City is the electronic and hydraulic control unit for the anti-lock brake system. It helps manage brake pressure so the wheels do not lock during hard braking. It also supports autonomous braking functions when the vehicle commands braking without pedal input.
On affected vans, the ABS module was built with a damaged damper membrane. That membrane sits inside the module and helps control pressure pulses in the brake fluid circuit. When the membrane is damaged, the module does not control brake pressure as designed. The result is reduced braking performance or loss of autonomous braking functions.
There is no warning sign before failure. An owner should not count on a light, sound, or pedal change before the ABS module stops doing its braking job.

What's the safety risk?
Loss of braking performance or autonomous braking functions can make the vehicle harder to stop and increase the risk of a crash without prior warning. Schedule the recall repair soon, and avoid relying on autonomous braking as a substitute for normal pedal braking. Repair is free at any franchised Ram dealer.
