Monday morning I got the same "Service Brake Assist" warning message. Brake pedal felt strange. A lot more pedal travel, and the pedal was pulsing like the anti lock brake system was activating. Drove to work, and the entire time the problem persisted. Drove home, same situation. Called dealership and made a service appointment. Next day, no issues at all, no warning message, and brakes felt normal. Today, same thing. Truck performed normally.
Dealership is claiming they have already performed the service associated to the recall for this issue. Must have happened while the truck was in for an oil change, because this is the first time I've seen the "Service Brake Assist" message.
Has anyone had this issue, and had the dealership correct it? I'm interested in specifically what the dealership did to correct the problem. Is this a software refresh type of thing, or is there a part requiring replacement?
