Mercury Mariner Hybrid brake failure problems

In stop and go city traffic going about 1 mile an hour I braked but my mariner didn't and I slowly rear ended another vehicle. My ABS sensor went on then off eventually an ABS regen light came on and I had no brakes so I drove ,very carefully, 83 miles to my ford dealer ( with no brakes) to find out that I needed a complete replacement of my ABS hybrid braking module. $3900! My mechanic and I called two different junk yards where we received replacements and they were installed but when brought back to the ford dealer the units wouldn't take the computer code and the (used) systems failed. $3900 is a lot of money for a vehicle, with 158,000 miles on it, that I bought used for under $5000. That said is there anyway that this ABS hybrid brake module should have been on a recall list. Are others having similar issues? Is this why they quit making hybrids at this time? I don't know but I'm thinking this is a recall issue at that price.

Tl* the contact called on behalf of his daughter who owns a 2008 mercury mariner hybrid. While driving 45 MPH, the re-gen brake disabled warning indicator illuminated and the brakes failed to operate as intended. When the contact turned off and restarted the vehicle, it operated as intended. The vehicle was taken to an independent mechanic where it was diagnosed that the hydraulic control unit needed to be replaced. The vehicle was not repaired. The contact stated that the failure was intermittent. The dealer was not contacted. The manufacturer was made aware of the failure. The approximate failure mileage was 150,000.

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

The ABS system turn off, took to shop they could not fine trouble it had reset. Today same thing ABS turn off. Will take it in if it does not reset. Both times that it turn off car was parked and I was just starting it to leave..*I would see a warning that says 'regen brake failure.' *the ABS just went out one day while coming home from the store, and would reset when the car sat for a while. And syre was not fun to drive, but unless it stayed off there was not much they could do at ford to fine out what was going on. It went off and stayed off and then ford fixed it, replaced the ABS module it has been o.k. Since then. I did not like the price of the repair at $1933.03. I do not think a women would be able to stop her car if this happen to her while driving you need too much push on the brake to stop even when going slow, and if going the speed posted two feet maybe*smch

Regenerative braking system light appeared on dash, 2013. Took vehicle in to get checked. Was told that it was the master cylinder. Cost approx 1500.00. Went on line and found that other people had same experience and after paying for the replacement of the master cylinder they then had to replace the an ABS module to the tune of 4500.00. Took my vehicle to another dealership feb of 2014 and was told the ABS module needed replaced for 4,724.00 and then the master cylinder for 1360.00. The mechanic did not advise driving due to the potential brake failure. I only have 18,600 miles on this vehicle which makes it difficult to justify putting that much more money into it. It seems to a problem ford needs to deal with. It does involve a safety issue and I'm not sure if they are going to wait until some one dies before they decide to do a recall.

I have a mercury mariner hybrid 2006. Coming up to red light and vehicle suddenly had no brakes, the pedal would not push in either. No lights had ever come on and no warning signs were ever received. The car was in great condition and was regularly taken care of and had preventable maintenance. Upon failure to brake I had to maneuver the vehicle in dangerous conditions just to avoid an accident. Lucky for me this time did not result in an accident or injury. After replacing the master brake cylinder (as per ford recommendations) I again had the same problem. This time, narrowly avoiding crashing into my other vehicle which was in my driveway. This was again, without any notice or warnings. Now, by researching online I find that this problem is existing and mercury / ford will do nothing about it because no serious injury has occurred yet? I can't afford to replace the hcu, so I will be trading in for another type of vehicle...sad to say. I would have stayed a loyal customer, if not for the sour taste in my mouth.

This vehicle has lost brakes 3 times. My now 17 year old daughter is the driver! The first time the brake pedal went to the floor and pumping it would not help. Putting the car in neutral and using the emergency brake was the only way to stop the car. A non-ford car technician told us it was a possible brake booster issue and the best thing to do would be for it to happen again and bring it to ford for the codes to be read. I drove the car for over a week and it would not repeat the problem. The second time was also around 40 MPH and pushing the brakes as hard as possible would only slightly stop the car and it would keep jumping forward. My daughter had to stop with the e-brake. I took it to ford for diagnosis and repair. Ford replaced the vacuum pump/hose assembly. Then 2 days later, she lost brakes again. Had to use e-brake to stop in busy traffic. The southeast region ford technician came to diagnosis this car. After 9 days at the shop the brake booster assembly was replaced. We have been told again that this should take care of the problem. Fyi ( each time the car lost brakes, by turning off the car and back on again it would regain them). I am now driving this car to determine if the issue is in fact taken care of. This has been a very scary situation - especially since my daughter is the driver of this vehicle. When reading automobile blogs it appears brakes are an issue not only with the mariner hybrid, but the escape hybrid as well. I would like this investigated.
