ABS brake light warning came on. Brakes pretty much stopped working without any prior warning to the lights. Had to depress the pedal all the way to get brakes. Very unsafe. Now the brake IS stuck on and the car doesn't move. Have talked to and read about several people that had the same issue. Why hasn't there been a recall yet?

"Takata recall" when I was leaving a store yesterday I noticed that my ABS, brake light came on along with a description indicating my check brake system. I never noticed an issue with my breaks prior to these signals coming on and my fianc's car had been functioning well for the last four years. I normally drive the SUV so when I noticed it said that I made sure the breaks were working when I started to move. I did notice that the breaks required more of a firm push when I was needing to come to a spot. I didn't have any accidents or caused me to run any stop lights or stop signs. however, after doing my own research I did find out that this IS a problem for the 2008 mercury mariners and from some of the warnings I have read stated the breaks ended up failing after this all accrued and about got them into accidents. with the nhtsa already investigating the '2006-2012 fusion and lincoln MKZ and the 2006-2011 mercury milan' models with the same issues, it seems the issue IS bigger than just the mercury mariner.

We bought vehicle in jan, 2018 from a private party, as a work vehicle for my husband, who IS a usps rural route carrier. Two weeks after purchase, the anti-lock brake light went on, and the car would not stop when it was supposed to, which was very dangerous in winter. We believe the prior owner knew about this. The light would just go on & off with no pattern. About 1 1/2 months later, he was driving on a 2 lane hgwy (55 mph) delivering mail. He went to pull forward but the car made a brief noise and then everything just stopped working. The car wouldn't start, no electrical or lights, he could not even roll the vehicle by himself to a safe place w/out help. The electrical and propulsion simply stopped working; period. We ended up dragging it home. Dealership gave est. Amt of repairs around $18K. I found the recall in 2014 (14s19) for the same thing. The mec pump was replaced in 2014, with a "supplemental" fix in 2015 same issue. This IS the exact same issue as the previous recall, which neither mercury or any dealership wants to honor. I'm guessing there are more hybrid mariners w/ similar issues, but not enough to issue a follow-up recall. So here we are stuck in car repair purgatory. I do believe they should honor the recall now and fix the pump and replace the hybrid battery. Not sure about the brakes, but I have seen a lot of complaints about them as well - again, not enough for a recall, which again. Purgatory. My husband was very lucky. Had it been a diff time of day there would have been much more car & semi-truck traffic on the hwy (speed limit IS 55) and with him literally just stopped dead in his tracks, there surely would have an imminent risk of a serious rear-end collison, with potentially deadly injuries. I am looking for help, assistance, guidance and anything else from any source possible to resolve this issue. We are at our witts end!!

ABS light came on and brake system failed to stop the vehicle until pressed hard the brake pedal. The ABS light comes on and off. Gave the vehicle for diagnostics to mechanic - codes u0418 invalid data from brake control module, codes c1478, c1479, c1480, wheel brake pressure control plausibility, u2023 communication network fault, mechanic gave estimate of $5542.00 to replace ABS control assembly. I called ford customer service, they declined to assist at this time. No help provided to put my vehicle back on road. This IS a safety issue.

Very dangerous! Had recall work done on the mecs 3YRS ago but problem has continued. This happens while in motion on the 110 freeway in downtown los angleles, ca. could be the electric throttle body or rear actuator. Or any other component that works with the electric motor and battery.

Heading west on the interstate I took the off ramp and came to a stop. as I was stopping a tone rang out, the ABS light, and brake warning light came on. the brakes didn't feel as stiff as they should have but I did come to a stop as I wasn't traveling very fast while approaching the stop sign. I turned left and proceeded over the overpass towards a side road when a car that had come up the off ramp from the eastbound lane rolled the stop sign and stopped with the nose of their vehicle in my lane. I nearly put the brake pedal through the floor and had little to no brakes to stop me. I and made a split second decision to swerve around the car, driving in the oncoming lane as I was able verify there was no oncoming traffic. Once I pulled over on a side road I noticed the display in the dash read "regen brake disabled" I drove slowly to a small car sales lot with an auto shop and they researched for a few minutes and told me I would have to take it to a dealer to replace a hydraulic pump. they were able to fix the issue by disconnecting the battery for a bit but said more than likely the fix wouldn't last. next stop IS the ford dealer but from what I've read tonight, many other users have experienced the same issue and have been quoted over half the book value of the vehicle to fix the issue. I was glad not to slam into the passenger door of the lady who pulled out in front of me, I was glad I had a clear lane to avoid her without having a head-on collision but I can see where this issue could happen at the wrong time and place and cause harm or loss of life for those involved. because I had little to no brakes with the pedal pushed all the way to the floor

I have a 14s05 hard steering, power steering control pump no longer works. This causes my brakes to seize up. The diagnostic also indicates codes c1480 r/f, c1478 l/f, c1313b r/f. Indicating. Brake failure. I am driving this car to commute 45 miles each way to work daily. I am very afraid because this car IS a hazard. My vin# does not show that this car IS among the group that have a problem but. I do have it. Ford IS aware, why should I have to pay for the cover up of their error? It IS very difficult to drive, an extreme effort IS needed to make any turn, the turn radius has increased I cannot safely turn a corner in the city or on an off ramp. The steering wheel and tires immediately snap back to the forward position

Hcu module failure at 60,000 miles. This failure IS mentioned intsb 05-8-5 & in nhtsa ID# 10017553 this seems to be a recurring problem in many ford escape/ mercury mariner hybrids going back to 2005. my dealer estimated the cost to be almost $6000. this IS very disturbing, especially since this vehicle has been well maintained since purchased in 2009. IS ford going investigate this problem? Can you do anything to help with the financial burden placed on an owner of one of your vehicles? We have purchased a number of ford products over the years & feel that customer loyalty should be considered. I have lost faith in ford since this has occurred. I have decided to notify you of this situation since this repair cost IS out of the question. Thank you for your consideration in this matter.

ABS warning light comes on and check brake system message comes on at anytime while driving on sitting still. Lose braking power, causing driver to push brake very hard to stop and brake pedal sometimes goes to the floor and you have to use emergency brake to stop. Dealer couldn't look at the car for three weeks said its okay to drive in "manual mode", however manual mode only uses rear brakes and will take vehicle a long distance to stop in rainy conditions.(i went through a busy intersection in the rain and almost had an accident so left it at the dealer). Dealer had vehicle for almost six weeks, replaced the ABS huc twice, finally called ford. Ford advised to replace all brake hoses "due to restrictions". Dealers are telling owners they have to replace ABS hcu and part alone cost $4700.00. However, ford knows of the problem and IS not putting out a bulletin or recall, until someone gets killed. Owners are trading the unsafe car because the dealer IS misdiagnosing the real problem which cost approximately $300.00

On May 27, 2014, amended June 2, 2014, Ford Motor Company (Ford) submitted a Defect Information Report (DIR) to NHTSA describing a safety defect that may result in a sudden loss of power steering assist while driving in approximately 746,067 model year (MY) 2008 through 2011 Ford Escape vehicles equipped with electric power assisted steering (NHTSA 14V-284, Ford 14S05). Ford's DIR described the defect condition as a poor signal to noise ratio [SNR] in the torque sensor within the Electric Power Assisted Steering (EPAS) system [which] does not allow the PSCM to determine the driver's steering input. When the system detects this fault condition, it transitions the EPAS system to the fail-safe/manual steering mode.Ford's DIR indicates that loss of power steering assist while driving would require higher steering effort at lower vehicle speeds, which may result in an increased risk of a crash.Ford's remedy instructs dealers to check the Power Steering Control Module (PSCM) for Diagnostic Trouble Codes (DTCs) to determine the proper repair procedure. If no DTCs are present, dealers are to update the PSCM and instrument cluster module software. The updated PSCM software changes the torque sensor fault strategy so that the SNR condition does not result in a loss of power steering assist while driving.In addition, audible and visual warnings are provided for torque sensor faults.If DTCs indicating faults in the torque sensor, PSCM or Power Steering Motor (motor) are present in the initial recall inspection, the dealer performs the following repairs: 1) replaces the torque sensor for torque sensor faults (DTC B2278); or 2) replaces the steering column for faults related to the PSCM (DTC B1342) or motor (DTC B2277).Continued in attachment pages
