2012 Lincoln MKZ Hybrid: ABS light or ABS activating

Filed Jun 4, 2026 · Brakes · VA

I have a Lincoln MKZ Hybrid 2012 with 88k miles on it. While I was slowing to a stop as I approached a stoplight at a busy intersection, the 'Check Brake' warning on the dashboard lit up without warning and no prior issues, and my ability to brake became near impossible as the pedal softened. I needed to push it all the way to the floor to get the vehicle to stop. I shifted into park and turned off the vehicle - following turning it back on, the dashboard warning disappeared, I was able to brake again, and the warning has not come back since. My vehicle just passed inspection earlier in the month, and nothing with the brakes came up. This is a critical safety issue! It could have been potentially fatal to myself, my passenger, or other drivers if I could not stop before the intersection, or if this had happened while I was on a main road or highway. I took it into the Ford Lincoln dealership. They cited a faulty HCU/ABS module and recommended replacement, but all parts are after-market at this point and would not come with a warranty. OEM replacements are also extremely difficult to come by. The repairs would take around $3.8k to complete, which is close to the current value of the vehicle. Ford issued Safety Recall 19S54 in December 2019, covering 600,166 model year 2006–2010 Ford Fusion, Mercury Milan, Lincoln Zephyr, and Lincoln MKZ vehicles for the exact same defect. No recall exists for anything in 2012 despite at least 17 the federal safety agency complaints have been filed for the 2012 Lincoln MKZ alone for this specific brake failure. The 2012 MKZ and Fusion use the same braking system architecture as the recalled vehicles. The failure mechanism is identical. The safety risk is identical.

Started vehicle in parking lot. Brake light, ABS, traction control lights all on. Backed out of parking spot. Thought I could get it home. Pulled out onto city street. Total brake failure; pedal went all the way down. Did not remember to use emergency brake to stop, but put into park to get vehicle to stop. Managed to pull into another parking lot, continuing to put into park to stop. Called aaa and had towed. Dealer invoice states, "verified cust concern. Experienced no power brake assist on vehicle. R&I the ABS control module for internal fault...."

Traveling south on ct15 in stop and go traffic. Traffic was moving at about 40 MPH and stopped suddenly. I applied presuure to brake pedal to stop. Pedal went to floor. It appeared that minimual regenerative braking was engaged but no additional friction braking. Car had plenty of distance in which to stop [ more than 140 feet]. Car slowed for a time but when speed was reduced to about 10 MPH, the regenerative braking disengaged and car surged forward and rear ended truck causing substantial body damage. No warning lights were lite on dash. Dealers had inspected brake both before and after crash and reported no problems. Simulated brake assist did not provide any resistance to pressure on pedal. Brake pedal position sensor did not generate brake request or ABS and ECM did not recongnize request for extra braking. Extreme pressure on brake pedal did not activate fail/safe manual friction braking. Car should stop in 140 feet from 60 MPH. Questions - what was the cause of the sba not activating? Why did the ABS and ECM ignore or not properly respond to the braking request? Why the fail/safe friction braking mode fail to activate? What pedal pressure is required to activate mode? There are numerous prior reports of similar symptoms causing accidents in 2011/2012 lincoln/ford hybrids. What is the stopping distance from 60 MPH in fail/safe mode. Ford literature on the hybrid braking system does not speak to this issue or give any warning to customers. How is the fail/safe friction braking system tested to insure proper operation in an emergency? Why does the brake pedal go to the floor when driver is attempting a panic stop?
