While driving on the highway at 7:15am I was using the rear window defroster to melt the ice on the rear window. It was 24 degrees Fahrenheit outside. The drivers side rear window pane (3 paned rear window) shattered. The window that shattered is where the connections for the rear defrost are located. There were no holes or impact points on the window.

The electronic assisted power steering pump is going out on my truck. It gave me no warning lights or signs that it was going to fail. I was driving into a curve and my steering wheel locked up I was able to still control my vehicle but it was hard to turn. It has then started making noise and wants to lock up when I turn. I brought my truck to Ford and they're using a scapegoat not to cover it under my extended warranty and blaming it on a modification to the vehicle.

Just had my 2012 F150 FX4 super crew appearance package rear window shatter. Last night my truck is sitting all by its self on a flat surface I hit the automatic start as I'm walking out to my truck it's about 22 deg F out I hear this loud pop didn't know what it was then in the morning I noticed my right rear window was shattered. Hopefully Ford will cover this if not there's a chance my aftermarket warranty will or I will file a collision claim through my insurance. The seames to be an ongoing problem with these trucks and Ford should take the responsibility to correct it. I love my F150 have had it since brand new it's been great up until now besides the radio modular need replaced when it was just over a year old. Warranty took care of that no problem.

While I was warming my F 150 in my driveway for departure to work, I heard very very loud thump sound coming from the rear window. Assuming maybe I opened my driver side door to far and wide upon getting in, that may have made the thump sound. But as I continued to drive out of my driveway, and proceeded a half mile down the street, I notice tiny small spider fragments on the right end of the 3 panel rear window. I first assumed it was mist dropping from the window but all the other windows on the truck were dry & clear. So I pulled over to get out to check to see if it was truly cracked and damaged. And yes indeed!!! it was the rear right side panel window damaged. I remembered the very loud thump sound that occurred five minutes ago and saw that my defrost was light flicking and now I realize that the rear defrost must have a defect, because I never experience this ever before on any other vehicles I owned and considering I only have less than 37000 miles there must be a major defect with the F150 rear panel windows. If you have any information regarding the Ford F-150 please contact me because this is unsafe especially when you have small children, or any passengers sitting in the rear. I'm just thankful there was no one in the rear. The cost to repair is extremely costly considering that the entire rear panel window has to be replace, this isn't fair to the consumers.

I started my 2012 F-150 and activated the front and rear defrosters. While idling in a driveway, I heard a loud pop, looked around and realized my passenger side rear windshield panel had shattered spider web style. Luckily I turned off the defroster in time and was able to duct tape the broken window. Unfortunately, tiny splinters of glass were already on my rear passenger seat, and I got some in my hands from taping it up. Thank god nobody was sitting in that seat. Temperature was low 40S, I was trying to get rid of a slight frost.

Takata recall. I recently purchased a 2012 F150 FX4. While driving on a secondary highway at about 55mph I heard what sounded like a gun shot. Upon immediate inspection I found the rear window behind the driver had shattered into a thousand pieces.

I was cruising down the highway when all of sudden the truck would not accelerate and it felt like the engine had shut off. The RPM was fine, however on the speedometer it kept going up and down (my mph was all over the place), and it felt like some one was pumping the brakes (lightly). I tried accelerating but all it did was make a screeching sound. I had to pull over to prevent cars from rear ending me and placed in park. I noticed that the engine was still on at this point and pulled back out on the highway with no further problems. A few days later, I took it to a dealership which they ran a diagnostics and found no issues. On my way home from the dealership, I experienced the same thing as I was exiting I35.

Back passanger side loud boom window busted when defrost cut

- Youngsville, NC, USA

The below problem has repeated itself more than 20 times since the first incident. When parked overnight or over a long period of time, upon starting and operating the truck - either reverse or drive - the brakes fail to engage the first one or two times. Had to either hit the brakes very hard or I had to revert the truck to P(parking) position. This just about works to bring the truck to a halt, but even this failed a couple of times when D(driving forward). Thankfully, no one was around for 10 meters. This has led me to only starting the vehicle when there is no person/object either in front or the rear. It is high-risk each time given the damage the truck can do if it collides into something. It is not readily reproducible as it works fine thereafter and hence could not prove it exists to Ford technicians. Reported it first to Ford along with an E-brake issue on 02/12/2015. They replaced the E-brake but brushed off this issue saying it could be rust and it's normal on vehicles parked for long. However the frequency has increased of late and I see quite a few Ford owners having the same issue on Ford forums. The possible issues could be the vacuum pump failing, but Ford technicians claim to have never heard of this problem. Really at a loss and hope Ford sends out a bulletin to fix this asap. This is not a joke. It's life threatening and could cause real damage very soon.

Internet research yields common problem with 2009 and later model year Ford F150 tire pressure monitoring system. Tire pressure monitoring system fault occurs, cannot be reset, is expensive to repair, and frequently fails again. Consumers are operating vehicles, ignoring the sensor fault display. Ford should extend warranty to 10 years, 100,000 miles until engineering deficiencies are resolved.

Rear defroster stopped functioning. Fortunately for me the rear window did not blow out as has happened with other F150's as listed in "glassbytes.com". many say it sounds like a gun shot. This site also has a service record stating that some F150's rear defrosters will not work for years 2010 - 2013. The Ford dealership said I would need the rear window replaced. Since I was under warranty for mileage, but not for the time, Ford said they would cover $600 of the approximate $1200 cost. I told them this was a safety issue because my rear window could have blown out like others have. There is a picture on the internet that shows the window temperature at 140 degrees on one vehicle. Ford should have a recall on this defective product.

Back glass window on driver's side shattered while using the rear defroster

I have read that this is a rain or humidity problem with the ecoboost engines. This has happen on and off from new and now seems to be getting worse. With a family of 6, I will be replacing this vehicle as soon as finances allow.

Noisy electronic vacuum pump issue. At aprox 45,000 miles I noticed a noise in the engine compartment near the drivers side tire. I took it to a local Ford dealer. The first time it would not make the noise. The second time it made the noise it made the noise. I was advised I needed a new vacuum pump. I was also advised it was not covered by warranty because my truck was over 3 years old and over 36000 miles. However while researching this matter I find there has been and issue with the vacuum pump on several Ford vehicles. I believe should take responsibility and take care of all costs associated with this issue. I am not the only one with this issue. My cost of repair is $724.27

Ford fixed my rear window, no questions asked....this is what happened....I started my truck, put on the rear defrost, drove out of my apartment complex and as I was about to exit the complex I heard a loud pop/crack noise, I stopped, no one was around, (it was 6am in the morning), I checked the entire truck to see what it was and the back left part of the rear window was completely shattered!, no sign of impact, just shattered...apparently there is no recall out on it, so if it has happened to you or does happen, take it in!, with how many complaints I have already read, it must be a manufacturer defect related to the rear defrost or installation of the window....

I was getting ready to get our of my house with my son. While we were locking our seat-belts, I heard a loud bang and when I turned, the back right rear window behind my son's head was all shattered.nothing hit it as the truck was standing with the windows facing my house, it just exploded on its own.

At a stoplight I activated the rear window defroster. After approximately 30 seconds I heard a sharp large cracking sound. Upon investigation I found the driver side rear window was shattered but still in place. No signs of chips from inside vehicle or outside were seen before the incident. After getting back inside the vehicle I noticed the rear defroster was inoperable.

My wife and duaghter were driving down I-75 when she heard a couple of chimes followed by a message to safely shut down. The truck lost all power at that point and the engine turned off by itself. She wjoshuaas lucky she was already in the right lane and was able to get off the interstate prior to anything too bad happening. I had already done some research and found Ford has had an issue with the 4 egt exsensors shutting the vehicle down to protect engine. This is a very serious safety issue if you consider I could have been towing 17,000lb trailer behind me when this could happen. I strongly feel that Ford needs to address the bad sensors quickly before something worse happens. My truck has had no modifications nor chips in it, sensors go bad and kills the engine. Only 34,000 miles on it.

When taking off from being stopped there is a thumping, clicking, snapping type sound coming from the rear of the truck. Not only does it make a noise but you can feel it. Truck was taken into the dealer for inspection and dealer could not find out where it was coming from. Updated 4/24/2015
