Service Brakes Problems of Mercury Mariner Hybrid

When slowing for a stop sign on a suburban street, the vehicle lost all braking power. (it had shown no prior problems. ) we had the vehicle checked - both front hydraulic lines had broken.

I put my 2006 Mercury Mariner Hybrid into reverse to back out of my drive way. I applied a little gas and began rolling down the incline towards the street. As I approached the street I put on my brakes, but nothing happened and I failed to slow down. A code displayed on my dash reading, "regen brakes" the last word was either failure or disabled. I can't remember because I was in a panic about my brakes not working with my family in the car. I applied the brakes again. The brake pedal was hard to push and though I tried with all my strength, it did not stop the car. My husband then pulled the parking brake from the passenger seat. I turned the car off to collect myself, hoping the failure was some weird fluke, and turned the car back on. It immediately did the same failure. At this point, I put the car in park and my husband offered to drive it around the block and back into the garage. It never showed another code afterwards. We left the car for a few hours and then cautiously drove it to the gas station. No more codes or issues. However, we no longer feel we can safely drive the car as we have no idea when the brakes could go out again. Next time we may not be so fortunate as to be on a residential street with no other traffic.

I have abs, brake warning and regen brakes disabled messages on dash. Ford mechanic estimated cost over 5k.

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.

The contact owns a 2007 Mercury Mariner Hybrid. While driving approximately 60 mph, the brake pedal traveled to the floorboard before the vehicle stopped. The anti-lock brake system and the brake indicators illuminated. The contact stated that the failure occurred five other times intermittently. Once the vehicle was turned off and restarted, the failure would stop. The vehicle was taken to the dealer (ed whittmeier Ford in chico, California) for diagnostic testing, but the failure could not be duplicated. The manufacturer was notified of the failure. The vehicle was not repaired. The approximate failure mileage was 84,000.

Tl the contact owns a 2008 Mercury Mariner Hybrid. While driving approximately 30 mph, the abs and brake warning indicators illuminated. The brake pedal was depressed to the floorboard to stop the vehicle. The vehicle was taken to roesch Ford (333 w grand Ave, bensenville, IL 60106, (630) 279-6000) where it was diagnosed that the hydraulic control unit failed and needed to be replaced; however, the failure recurred. The vehicle was taken to an independent mechanic where it was diagnosed that the hydraulic control unit failed. The vehicle was repaired, but the failure recurred a third time. The vehicle was not repaired again. The manufacturer was notified of the failures and referred the contact to NHTSA. The approximate failure mileage was 94,000. The VIN was not available.

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. .

The brake system's hydraulic control unit ("hcu"). On several occasions while driving, the brake pedal will travel to the floor while trying to brake resulting in no braking action (ie. , vehicle not slowing). This might happen for one or two pedal depressions before there is any slowing of the vehicle. This problem has placed me in situations where I have to take evasive action to not hit a vehicle in front of me, or traveling into a controlled (with stop signs) intersection. Below there is a space to specify 'when did this happen. ' I am inputting the most recent date of this problem, but it has happened at least ten times before this.

While driving on the freeway, I hit the brakes and they stopped working. On the dashboard it said that brakes needed to be serviced. Luckily I was able to stop by putting most of my weight on the brake pedal. I pulled to the side and inspected the car, nothing was wrong. I proceeded to restart the car and the brakes appeared to be working fine. I took the car to the Ford dealership and they verified that an issue had occurred, however they did not know how to fix the issue and contacted Ford. After 4 days they claim that a tube was defective and that the brakes are fixed. No car should have a failure that causes someone the inability to stop, this is poor engineering. All cars should have a fail safe that allows to the car to stop in event of catastrophic failure. What makes the incident odd is that restarting the car fixed the problem for me, allowing me to drive it to a dealership.

When braking it takes the vehicle along time to come to a stop while driving dealer says that the hydraulic control unit is bad ( hcu ) they want 4,000 dollars to fix it.

Tl-the contact owns a 2007 Mercury Mariner Hybrid. The contact stated that while driving approximately 65 mph, the vehicle stalled as the check four by four, service brakes, and pull over safely warning light illuminated. The vehicle was not diagnosed or repaired. The contact mentioned that when the brakes was depressed, the vehicle jerked forward as the traction control warning light illuminated. The vehicle was taken to an independent mechanic but the failure was unable to be diagnosed. The manufacturer was not notified of the failure. The failure mileage was 65,000. Ss.

The warning lights had come on a few days ago stating to check the brakes. Today, when the engine was started, the message stop safely now came on. This does not tell me anything about what I need to do and how critical this error is. Can I drive it to the repair shop or should I have it towed? what has to be replaced? this car is driven by my son who is an inexperienced driver, so this is a major concern.

While driving down the road, all of the warning lights on the dash board came on and then the breaks failed. We were able to get to safety after going off the road. When taken into the Ford motor company repair shop they reset the codes and said everything was fine, no parts to repair. Less than 50 miles later, the same thing happened again injuring 3! this time it's the abs module. After calling the Ford motor company, they refuse to admit there is any problem and no reason for a recall. We were given the NHTSA information to make a complaint and if eventually NHTSA informs Ford that they must do a recall we can be given a refund for our money spent on this repair. Our question is what happens when someone dies? does it take that before someone is going to do something about the known hybrid breaking problems? the manger at the Ford motor company customer service doesn't think it's an issue worth looking into only to say that a vehicle with high mileage should be taken care of and repaired by the owners. Not that Ford is responsible for faulty parts! please NHTSA do something about the hybrid breaking system before multiple people continue to be injured or are killed!.

When decelerating down hill the brakes became seemed to have no power to stop the car and required extreme force to stop the car. Afterwards the electronic motor disengaged from the engine and the automobile runs on combustion engine only without the hybrid electric motor assist.

The abs tone rings on the 2008 model Mercury mariner and Ford escape are defective in design - they are thin metal, but put under stress by being forced onto the half-shaft (different metal, different expansion rate), and therefore prone to cracking/breaking. When cracked/broken, they cause the abs brake system and regenerative braking to fault out, sometimes intermittently and with no warning. The part itself is cheap (~$10 each), and apparently should be, but the dealer will not sell them separately, and instead requires the owner to replace the half-shaft, with estimates from the dealership and independent mechanics of between $400 and $1000 to replace both front half-shafts. Simply making the part thicker, or of the same metal as the half-shaft, would fix the problem - instead, Ford forces owners to choose between an unsafe vehicle and robbery, with no guarantee that the problem wouldn't recur within a month of driving (the cracking seems to be more related to temperature than mileage). This should be recalled and Ford should be forced to replace these at their own cost - I bet they'd then "discover" a way to prevent recurrence if they were paying out of their own pocket for any that failed before 100,000 miles. A cursory search on the internet will turn up thousands of results for this problem.

My son was coming to an intersection of a main road from a side street and when he went to step on the break the SUV would not stop he didn't expect this and pushed down as hard as he could if stopped out in the main road lucky no one was out there. I have checked on the web and a lot of people have had the same problem it seam to be something with the electric brake system that stops the SUV. I uses mostly the regenerating system to stop the SUV not the pad only a little is use so if the system has a problem you have a danger of not stopping as quickly as expected. . . . . You may have an major problem from what I under stand there are a few thing that can cause this contition. . . .

From doing research on the internet I found this is a huge problem with both Mercury mariners and Ford escape hybrids. I was in shock when the dealer told me it will cost $4,800. 00 to repair the abs brakes. This is a safety flaw that should be a recall. I only have 65,000 miles and high payments on this vehicle. I told the dealer I would not pay this. They fixed the SUV without my permission saying it was for my safety. Is this legal? I didn't agree with paying any cost.

During braking to stop or turn, the brakes engaged and released at low speed then reengaged, causing a lerch. This problem was ongoing but intermittent. Upon researching the issue and after separate service visits to two different Ford dealers, with my input from online forums, the tone rings on both front brakes were replaced, resolving the problem. These rings were cracked and according to the dealer, this is a common problem and I think these parts are defective.

Intermittent failure of the abs system due to broken abs exciter ring. Caused uncontrolled skidding on smooth parking lot and jittery braking in traffic conditions at about 30 mph.

Tone rings have been failing annually. This causes the brakes to pulsate, rather than come to a complete and predictable stop, and disables the anti-lock brake system until tone rings can be replaced.

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 probelm. The second time was also around 40 mph and pushing the brakes as hard as posible 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 agian 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.

Brakes bring vehicle to stop then release and car moves forward 4-6' then brakes engage again. Could cause damage and personal injury.

I have a 2008 Mercury Mariner Hybrid. Sometimes when I apply the brakes with medium pressure the left rear of the vehicle will vibrate so hard it rattles the trim in the storage area. It is as though the abs is operating only on that wheel but much more pronounced than when the abs normally actuates. There is no consistency as to when or where this condition occurs. It will not happen for days, then will occur every time I brake for a time period (no particular length).

Mercury Mariner Hybrid 2009 had it for 18 months and August 3, 2010 upon an approach to a stop light engaging the brakes I heard an audible warning sound and looked at my console to see the warning to check brakes, at that moment my brake pedal went soft and to the floor, I had to apply the emergency brake to stop the mariner to avoid hitting the vehicle in front of me. I parked ASAP in a gas station leaving the mariner and calling for a ride back to my office to pick up another vehicle to get home and the next morning contacted my dealership instructing me to contact Ford to get it towed to them, later that day I get a call from the service department telling me that it was not covered under warranty because I had 40,000 mile on a 18 month vehicle and the repair cost is $1,700. 00. My wife and self could have been injured or worse. I will be willing to cooperate to any extent to help escalate this concern as a safety recall issue.

Was slowing to make a turn and the anti-lock/skid kicked in on dry pavement. Continued to occur through day with service brake warning and service 4x4 warning coming on. Brakes were replaced, rotors turned & system bled. Al/s stick kicks in while going slow on occasion. It's like the brakes lock-up and release three or four times then everything is normal until the next time. Vehicle is a 2006 Mercury Mariner Hybrid with 36900 miles. Hpa pump was replaced last year under warranty.

With the recent announcement of a software glitch on the fusion and milan hybrids, I have had similar occurrences on my 2006 Mercury hybrid, where it felt like I was trying to stop on wet leaves. It seemed like braking was fine initially, then it faded (as I described above) but with more pressure on the pedal, it did return to "normal" braking. This has happened only about 3 or 4 times of the 3 years of ownership, and I have not taken it to a dealer. I initially thought it was due to wet brakes, and thought nothing further of it. But given the recent recall by Ford, I thought it was necessary to at least report the occurrences. Date indicated is an approximation of one of the occurrences, which was just after I had surgery.
