2010 Ford Flex: brake failure

Filed Mar 20, 2019 · Brakes · 60,000 miles · CA

I recently experienced a brake failure on our 2010 ford flex. The right rear brake hose failed due to contact with the tire. This resulted in the brake pedal going to the floor and a significant decrease in braking performance. The brake hose failure was the result of improper routing of the brake line that happened when the caliper was replaced. The issue here is that the brake warning light never activated even after the brake pedal went to the floor several times. I have checked the bulb by putting the car in the run position and found that the brake warning light does illuminate at that time. This happened during normal city driving (no heavy traffic, speeds between 0 and 45 MPH, stopping at red lights and slowing for turns)

While driving 30 MPH the car simply dies. All lights come on and the car just shuts off. Left with no brakes, steering, or control. Dealer brought in engineer, after a week with the car dealer cannot replicate problem. Ford motor company decides nothing is wrong and force me to take dangerous car back. Incident occurred twice in the month of april/may.

I am the owner of a 2010 ford flex, VIN #[xxx]. My vehicle suffers from episodic brake failures. This occurs as the vehicle is first driven off and the engine is cold. Braking power is then reduced to 10% of normal, resulting in alarmingly long stopping distances. Once driven a few miles the brakes resume normal function. The issue surfaced at 20,000 miles in january 2010. The vehicle was serviced under warranty for this problem at least 4 times. This issue has been pinpointed to a probable vacuum loss present only on these vehicles that are driven at altitude above 7000 feet and share the flexes?? Ecoboost awd drive train. I live at 9000 ft. The service manager at my local dealership, summit ford of silverthorne colorado, has acknowledged I am not alone with a vehicle experiencing this dangerous mechanical problem but admits to being unable to fix it and has nothing further to offer. To date I have not been involved in a collision. However in the last 12 months I have had a few distressing close calls. Ford motor co. Was initially alerted of this situation by phone in april 2010 with a call to their consumer resolution center. My request for help is being ignored by ford motor company. My phone calls are not returned, my emails are ignored, even certified mail is not acknowledged. It has been my desire to work with ford motor company on solving this issue but I have exhausted all avenues. Ford refuses to acknowledge my communications, ford has been alerted to this public safety issue but has obviously chosen to disregard it. I hope alerting this organization will generate some action before an injury occurs. Information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6).

2010 ford flex bad brake issue. I live at high altitude and have a ford flex eco boost that performed flawlessly up until about 21k miles when we had a brake failure, the brakes did not stop the car. The dealer replaced a master brake booster and since that time we intermittently get a hard brake pedal and no matter how hard you push the pedal the car will not stop. There is another person also living at the same altitude about 9,200 feet in summit county co who had the exact same series of events although currently he is down in texas with no issues. A third person in wyoming who is about 6,000 feet is having the same problem. Ford claims there is nothing wrong with the car and have sent two engineers to look at it who have not experienced the hard pedal but the gm at the dealer has, never the less every once in a while especially when first starting out the brake pedal is hard and you have about 10% braking. My wife actually went through a red light for about 20 feet before she could finally stopped she was lucky no car was coming at the time. It only happens at high altitude apparently. Which means that people driving up into the mountains to go skiing or whatever may get an awful surprise if their brakes fail. I have posted under the www.fordflexforum.com and www.fordflex.net where you can see the replies from others with the same problem. As this problem did not occur up until about 21k miles for all three cars I know about there has to be a defective part somewhere. We are reluctant to use the car and are worried about consequences if we were to have an accident. We have reported direct to ford and have a contact with their customer service, the latest advice hire an independent engineer to verify their is an issue. I figured I would try the government. Thank you

Post re: flex died while driving down the road thurs jun 11, 2009 6:07 pm the same thing happened to my mom when she was driving hers through a parking lot, it just stalled out! She took it to the dealer the same day and they said they didn't find anything wrong with it. This was about a month ago and since then it has not happened again. I hope you have better luck with your dealer finding the problem. !@#$%!!!!!!!! It happened to me today!!!!!!! I was on my way to a meeting this morning and as I was going into a curve the car died!!! Kaput! Dead! No brakes, no power steering!!!! Thank god there was no oncoming traffic because I went straight into the other lane. And, thank goodness I had read this post a while ago so I knew immediately what had happened. I twisted the steering wheel hard to the right and rolled the car to the side of the street. Put it in park and restarted it. It started like nothing. I called my sa who obviously suggested I bring the car over right away, which I did. I also told him about this post and richmondflex's note on the tsb (thanks bud!). Since I had to leave the car, I'm also having them look at the brake problem, which is back. That was a scary moment this morning!!!! Post re: flex died while driving down the road fri jun 12, 2009 3:23 pm in another post I thought our steering locked up, but after talking to my wife, the same stall happened to us (long story on the actual event). Totally freaked her out to the point she wouldn't drive the car. I looked up on line to see if the car had any tsbs and it stated we didn't. I still took it to the dealer (not the one we bought it from) and had them look it up and lo and behold there it was. They say the issue occurs at less than 10 MPH. They reprogrammed the computer (it took 45 minutes) and said I should be good to go. For those that just had it happen or have yet to have it happen, go to your dealer, if nothing else for the peace of mind. My car has 2k miles on it.
