2015 Ford F-150 brakes complaints
Page 10 of 12: complaints 251 to 280 of 317, newest first, as owners wrote them.
While driving on 7/27/2017 around 9:00 am, a warning light came on that said low brake fluid. 5-10 minutes later when I went to slow down to take an on ramp, the brake pedal went to the floor. I had barely enough braking to slow the vehicle, and to find a safe place to leave the road. I had to be towed to my local ford dealership.
Tl* the contact owns a 2015 ford f-150. While driving approximately 60 MPH, a "brake fluid low" message displayed on the instrument panel. The contact slowed down and proceeded to the next exit before losing all braking ability. The contact downshifted and applied the emergency brake in order to stop the vehicle. The vehicle was taken to purvis ford of fredericksburg, virginia where it was diagnosed that the master cylinder failed, which caused brake fluid to leak into the brake booster. Both the master cylinder and brake booster needed replacement. The vehicle was repaired. The manufacturer was not contacted. The approximate failure mileage was 71,000.
I was driving south on I-75 just north of cincinnati, oh at approximately 65 MPH when a message came on dash and said something like "low of brake fluid". I tested my brakes and the brake pedal went to the floor. Traffic had simultaneously begun to slow so I down shifted the transmission, swerved from the slow lane to the shoulder and applied the emergency brake. I was able to get the truck to a complete stop. I lifted the hood and found no brake fluid. I called and waited for a tow truck. After two hours, since I had only driven 2 miles from my house I asked my son to bring me a quart of brake fluid and check the driveway to see if there was a spot on the concrete. There was no spot on concrete, I added an entire quart of fluid but still had no brakes. Had truck brought to kerry ford and repaired where they advised the brake master cylinder failed. Although the vehicle was only 18 mos old, the warranty was only 36,000 miles which I had passed. I bought the vehicle brand new. I paid for the repair but could not get the master cylinder from the dealer as I was told ford required the old one for a core.
Brake pedal going all the way to floor took to dealer he said noting was wrong same day took to local shop they replaced the master clydner and calipers the truck had 36400 miles the repair seam to fix the problem very strange that the dealer did not want to address the issue when coming to a stop break pedal with pressure would go to the floor felt like there was no pedal left by pumping break pedal you could get pressure back but it would go back to floor it also would do this stoped at red light
Was on a freeway exit. Traffic was heavy, and I was in stop and go traffic for about 10 minutes. I was just rolling forward and when I applied the brakes the pedal went down to near bottom and immediately warning lights came on indicating low brake fluid. I cleared the screen and continued carefully to my shop which was within a couple of miles. I added brake fluid to the max mark thinking I could nurse it to the dealer for repairs later in the day. When I attempted that trip several hours later the pedal went to the floor again and I had little or no brake power. I decided to have the truck towed and pulled back slowly into the parking space. I had no brake at this point and actually had to jam the transmission into park a couple of feet before hitting my own building. That is where the tow truck picked it up.
I was driving on the freeway at 65 miles per hour when I had a sudden warming light flash saying brake fluid problem. I tested the brakes and they went to the floor. Total brake failure with no warning. The truck has 29,000 miles and was serviced within last 2 months. This could have very bad and had tragic consequences. I fortunately was able to down shift using the manual shift feature and slow down and stop safely. This is a serious issue. My family and I could have been in a serious accident and hurt ourselves or others. Ford needs to get this figured out asap. Call me with any questions.
Brake master cylinder failed, pedal went to floor with no warning and almost crashed. Topped off brake fluid, and still no brakes. Pulled cap off vacuum booster and booster was full of brake fluid. Now truck is smoking badly I believe from brake fluid being sucked into vacuum hose. Only 30,000miles on truck 2015 f150 with 3.5l
3.5 liter v6 ecoboost sudden and complete loss of braking ability without warning brake pedal going to the floor with sudden and complete loss of brake effectiveness brake warning lamp illumination and low brake fluid level comes on after complete loss of brakes, slowed down with emergency brake luckily at low speed added 1 quart of dot4 brake fluid brake warning lamp illumination and low brake fluid level disappeared brake pedal went to the floor with sudden and complete loss of brake effectiveness brake warning lamp illumination and low brake fluid level did not come on until after brakes failed I did not have an accident but it was close. Took to shop with complete brake failure. Truck has 39000 miles. The vehicle was on a city street when the brakes failed. No fluid was detected under the vehicle even after adding 1 quart of dot 4 brake fluid and the brakes failed again.
I was driving the the truck this morning and after the 3rd traffic light suddenly I lost break and barely able to stop. I pulled to a gas station slowly. I noticed break fluid was below minimum. Filled up break fluid to maximum. I tried to drive to ford dealer ship but after a few minutes I had no break again so I had vehicle towed to veterens ford tampa.
I was driving on the street the brake indicator low brake fluid light came on suddenly. I stepped on the brake paddle and there were no brakes. I shifted to 1st gear and coasted to side of the street. I checked reservoir and it was very low. I filled the reservoir but was empty in a few minutes but I did not see any leaks anywhere.
Warning notice came on and a minute later brakes completely failed. Luckily I was driving very slowly on a military base.
As I was driving to work on a secondary street with very light traffic (thankfully), a warning flashed on dashboard regarding low brake fluid. When I touched the brake pedal it vibrated and as I depressed it went all the way to the floor where I had minimal stopping power. With very light traffic I went to a nearby auto parts store and purchased / installed 1 quart of brake fluid. By the time I drove 3 miles to my office, the brake pedal was again on the floor with minimal stopping power. I installed a second quart of fluid with absolutely no sign of a leak anywhere. I had the vehicle towed to the dealer where they advised the master cylinder was leaking the fluid into the booster assembly. They replaced the master cylinder and booster.
While driving on interstate i355 at 70 miles per hour without requiring brakes, I got a chime and then a message on the dash that my brake fluid reservoir was low, then my brake light went on. I checked the brake pedal and it went to the floor without stopping the truck. Luckily I was able to time my distance with traffic and switch lanes and exit the interstate. I managed to get the truck into a parking lot and then checked the brake fluid reservoir. The reservoir was very low, below the minimum level. I contacted a coworker who brought brake fluid to the site and we filled it and pumped the brake pedal. It seemed fine so I drove the truck again going to work. Within another mile the chime and warning came on the dash again. At that time I pulled out of traffic and parked the truck at a bank parking lot. I then called ford roadside assistance and had the truck brought to the nearest ford dealership for service. The dealership told me later that night that my master cylinder and my brake booster both failed and caused the issue. I checked on line and found that the federal safety agency is investigating this issue on 2015 ford f150 trucks with the v6 eco-boost engine, which is the same engine in my truck. Before the brake issue happened I drove approximately 5 miles and stopped at several red lights and intersections without any problems.
Tl* the contact owns a 2015 ford f-150. While the cruise control was activated, the vehicle braked abruptly. The collision warning indicator illuminated and a chiming sound was heard. The vehicle was taken to a local dealer (watertown ford located at 1600 9th ave se watertown, sd 57201) where it was diagnosed, but not repaired. The manufacturer was made aware of the failure and opened case number: 12350340. The failure mileage was 19,200.
I parked my vehicle at camping world. There was no indication that there was any problem with the brakes. I came out about one half hour later and got into my vehicle. I started the engine, put my foot on the brake pedal, put the gearshift in reverse and when I release the parking brake a warning came up on the dash that said "low brake fluid". The vehicle had just started moving in reverse. I stepped down on the service brake pedal in it went all the way to the floor, there was no braking action at all. I hade to use the parking brake to stop. This failure happened with no warning and was a total service brake failure. I found no leaks at the wheels or anywhere under the vehicle. My next stop was to pickup my 26 foot travel trailer to get ready for vacation. Ford emergency service had my vehicle towed to ron dupratt ford in dixon california for warranty repairs. I believe the problem involves the master cylinder/brake booster.
Spongy brakes and pedal goes low. A vehicle report was completed with the truck running connecting to ford via my cell phone. A issue was detected. Then run again. Detected again. Then run again a hour or so later and not detected. I see a recall inquiry has been open on 2015-2016 f150 with the v6 3.6l engine. Mine is a 5.0v8.
Sudden total brake failure. No ability to stop vehicle. Fortunately in a residential zone and was travelling at low speed.. Brake was functioning normally when driven to neighborhood retail shop. When re-entered the vehicle and began to accelerate, brake warning lamp lit and I had no braking ability!
Brake light came on lost all use of brakes whithin 5 minutes while driving 70 MPH on highway. I was driving with the flow of traffic on a flat surface.
With the vehicle stopped, the brake pedal slowly fades to the floor when applying a firm steady pressure. At this time, there is no apparent loss of holding power once the pedal has faded. With normal driving the brakes work and the vehicle does stop. When the pedal has faded to the floor it can be brought back up by pumping the pedal. Testing has not been done to determine the amount of holding power that remains or to validate what would happen in a hard-braking scenario. The problem was first noticed on 3/17/2017 and is completely repeatable every time it is checked. The dealer has agreed with these observations but has stated that ford will not back a replacement of the master cylinder because it is working.
Brake fluid leaked from brake master cylinder into brake booster. Result was loss of brakes very rapidly. Vehicle was moving when my wife noticed the loss of brakes. Leak could have occurred either while truck was stationary or moving.
This is the fourth time I'm reporting this. Although my vehicle should have qualified for ford's recall 15s29, I was never notified. But I have mentioned it to my dealer 3 or 4 different times. They always tell me there's nothing they can do. So here's the issue. When driving on the highway, my truck thinks I'm going to hit something and the alert lights and sounds come on (and once since I had adaptive cruise control on, it applied the brakes at 70 MPH). This is not safe. The dealerships say there is nothing they can do to fix my truck, yet the issue keeps happening.
While driving to work. Brake fluid low warning illuminated and complete loss of brakes. This came on very fast. Within 10 mins of leaving home. Further inspection, once at my office, found there was no brake fluid leaking from the lines, calipers, or exterior of master cylinder. Brake fluid must have leaked into the booster.
On february 17, 2016 I experienced total brake loss of my 2015 f-150. The brake loss occurred at low speed, less than 10mph. I had to frantically pump the brakes to stop on a flat level surface. Where the brake loss occurred there was no snow or ice. I took the vehicle to the ford dealer and they said they could not find any issues. No warning lights turned on. The vehicle brakes functioned normally until today when I again experienced total loss of brakes! Again it was at low speed, this time on a steep grade with minor snow accumulation. The anti lock brakes did not activate and the brake pedal went to the floor. I was barely able to stop the vehicle when I reached a level surface. As of today the brake pedal continues to go to the floor. The vehicle brakes seem to function ok at high speeds, however while parked at a stop light the pedal continues to depress. I called ford because I am very concerned about what is happening., however they do not seem to take the complaint seriously. I asked them to tow the vehicle to a dealership because it's under warranty and I also have roadside assistance and an extended warranty. I was told by ford that they could not tow it until next wednesday. I finally ended up driving an unsafe vehicle over 45 miles to a dealership. The vehicle will be looked at tomorrow, hopefully!!! This is a dangerous situation that has happened twice, and I feel ford is sweeping it under the rug. Please look into this before someone needlessly dies. Thank you!
Tl* the contact owns a 2015 ford f-150. The contact stated that while driving the vehicle at 70 MPH and coming to a stop, the brake pedal would push all the way to the floorboard. Upon pumping the brake pedal, the braking action would return to normal and stopped the vehicle. The vehicle was taken to a dealer where it was diagnosed that the brake master cylinder needed to be replaced and was repaired. After about 800 miles the failure re-occurred. The manufacturer was notified of the failures. The approximate failure mileage was 13,500.
Brake pedal bled off and message centar alerted of brake malfunction. Dealer to replace master cyl. And booster. I was stopped at a light when the incident happened.
Brake failure, no brake warning lights. Peddle provided some braking initially, then peddle fades to floor and braking diminishes to not able to hold vehicle to complete stop, even at idle speed. Pumping peddle will restore same sequence. I would think this would be extremely scary to novice drivers and cause injury, death or collision with high probability. Especially with absence of warning lamps indication. First time problem noted on near zero degree f. Morning shortly after leaving early am on highway. Suspect problem to be master brake cylinder. Brake fluid level has not changed, search for external leaks in braking systems revealed no visible leaks. Vehicle currently in to service this at francios ford bellville wi.
Tl* the contact owns a 2015 ford f-150. While accelerating from a complete stop at 5 MPH, the brakes seemed to drag on three occasions. The dealer diagnosed that the brakes had a soft pedal, but the cause of the failure was not determined. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 31,000.
"check brake system" lights keeps coming on for no reason when going 40mph or more.only one time I have experience some brake loss in pedal pressure it took longer to brake. Especially on freeway. Brake fluid keeps going low more then more then normal. I've check brakes each one and have found noting. Brake pads are good and clean brakes and rotor and still same problem. Brakes keeps making noise when braking. It happens all the time I get on freeway. "check brake system" . It happened second day out the dealer.
Brakes are rubbing and dealer has reground front disc brakes twice without fixing problem. Suspect that brake calipers are not completely disengaging after brakes are applied. Brake pedal will go all the way to the floor after applying brakes.
