May of 2021 will mark two years since I began having issues with my 2008 lincoln mkz ABS system. Lincoln officially issued a recall about my specific vehicle in january 2020. It is unacceptable for a fix to not yet have been established for this. I cannot sell my car as no one will buy it with the issue and I cannot trade my car for another one because the dealerships cannot sell the trade to a customer due to the recall. I am being held hostage by a car I cannot drive in inclement weather due to the ABS system not functioning properly.

Abs engaged on snowy road. Now, brake pedal is extremely soft/spongy...does not engage until pedal is fully depressed. County road. Straight-line stop. Replaced brake master cylinder and performed factory pressure/service bleed. Cause is certain to be the historically faulty ABS hcu/control module.

Went to stop in winter conditions and the brake pedal went to the floor. Almost rear ended the car at the stop sign, had to go to the shoulder to avoid hitting them. Now the ABS, traction control, and brake system light come on as soon as I reach 15 MPH. I have had all the rotors, calipers, and break pads replaced. Still having the same issue.

Brakes spontaneously went soft, during travel (30 MPH?). Changed master cylinder which seemed to resolve issue. Couple of weeks later, happened again uwhile in motion. Master cylinder changed 2nd time under warranty. Happened third time within weeks traveling about 50 MPH. The third time, it happened upon application of brakes (not aggressive) which caused ABS activation. Pulse was felt in brake pedal and immediately brakes pedal went soft (almost to floor). Pumping brake pedal firmed the brakes. Couple of days later, tested ABS on gravel road by aggressive braking, ABS activation and brakes went soft immediately during the action. Pumping up brakes resulted in firming, at top of brake pedal travel without slowing vehicle then into soft travel through 3/4 travel until firmed again at bottom of travel. Concern is that in the event of emergency braking which activates ABS, typical braking changes to 'soft pedal' (belief of failed brakes) and potential for panic and resulting collision. Dealer tested system today (10/03/2018) and could not diagnose any problem. No dash light was ever activated in any of the events described. No brake fluid leak detected, no loss of brake fluid.

After ABS function operates I have a lower than usual pedal travel. The brake pedal goes 3/4 of the way to the floor. After several hours of not using the vehicle the pedal will be back to normal. This condition has happened to me 3 times preceding ABS activation.
