External temperature was ~22degrees F, had rear window defroster and heated driver seat turned on. Front defroster was on and set to highest temperature. While driving at 25 mph, my son and I noticed a burning smell. He was seated in a booster, rear seat, passenger side. He advised that he could hear something behind him making noise. I looked back and observed smoke coming from behind the rear passenger headrest, where my son was seated. I looked forward to find a spot to pull over and then heard a loud bang. Looking back I saw the rear window was shattered on the passenger side. It is a sliding rear window with three sections, only the passenger section, directly behind my son was shattered. The glass remained in place, but shattered. I quickly pulled over, shut off the truck and removed my son. From the outside I can see the plastic lower corner melted where the passenger glass meets the center glass section. The rubber seal/molding was smoking and had melted and dripped down the back of the truck cab, between the cab and the truck bed/box. Inside there is a strong odor of burnt rubber or plastic.

I was leaving from work. I put my rear defroster on my rear sliding window. I heard a loud pop. I looked at the rear window when I arrived home. The passenger side rear sliding window was spider cracked all over. I can't believe there is no recall on this yet. Its pretty sad when you buy a fully loaded truck that costs over fifty grand, but you cant use the rear defrost because they malfunction. It's pretty obvious this is a problem...just do a search on the internet.

Warmed up car before church. Turned on front and rear defroster. Backed up, put it in drive and heard what sounded like something crashing into my roof or a gunshot. I stopped and inspected the steel body parts and could find nothing. Driving down the road I noticed in my rearview mirror that my right side of my sliding rear window had shattered. It remained in place. I took this into the dealer on Monday and they fixed it saying a reed switch had malfunctioned allowing the glass to get too hot and shattering.

It was frosty out and I turned on the rear defrost. A few blocks down the road, I heard a pop and my back window broke. I have the electronic sliding rear window.

Turned on rear defroster of power sliding rear window, right side passenger section cracked into pieces. No there was no hair line crack no impact to this window. Looked at the lower heat strip in the bottom left side of this panel and sure enough there are burn marks. Now the back defroster does not work at all. Did Ford stand behind their product. Absolutely not !! this is my 2nd Ford truck and as soon as I get rid of this one we will being going GM. Thank goodness this is shatter proof glass and was not blown out because my daughter was in her car seat right under this.

I got in the truck this morning and left the house, turned on rear defroster, and about 3 minutes later I heard a loud "pop"! I stopped and looked around but didn't find any since it was still dark out but once the sun came out I saw my rear passenger window, right above my daughter's child seat was shattered. Luckily she was not in there. I have spoke with dealership and they have denied any knowledge of this happening, but a simple search here and on the Ford forums show plenty of consumers having this problem. This should be a recall!

While I was driving I turned my rear defroster on and about 5 min later I heard a load bang, looked around to see what it was and saw the passenger portion of the rear window was completely shattered. There was no impact on the window are clue to why it shattered. So I looked online and found this to be a common issue with the 2010 F150 trucks with power rear sliders. My daughter's car seat is directly under that window! Ford denied any knowledge of this issue and insisted they were not responsible and wouldn't cover repairs. I then learned that Ford has changed the wiring design for this window, a design that keeps electrical surges from over heating the defroster. My concern is that a shattering window poses a huge safety issue and Ford should be held accountable for their failure to keep their customers and more importantly the children of those customers safe!

Vehicle stalled as if out of fuel, despite having been recently filled with gas. Fuel monitoring system (tank level gage and range computer) indicated that vehicle was using fuel at much higher rate than normal. For example, normal range of this truck when 36 gallon tank is full is approximately 570 miles. After 250 miles, gauge was showing tank out of fuel and range computer was instructing me to refuel. Refilling only required 15 gallons, indicating reduced tank storage capacity. After performing research via internet, suspected bent fuel pump mount due to failed tank purge valve. Brought vehicle to dealer for service who found stored P-1450 code which indicated a prior failure of the fuel vent purge valve. Dealer dropped the tank, removed the fuel pump assembly and verified that the mounting system for the pump assembly had been severely bent when tank collapsed under atmospheric pressure. Negative gage pressure inside of tank caused plastic fuel tank to collapse, severely bending fuel pump mounting hardware which is constructed of two 3/16" diameter steel rods. Apparently the purge valve failed and either there is no pressure relief system, or it failed. Dealer replaced pump and purge solenoid valve at owner cost of $950+. dealer indicated that there was no liability from either dealer or manufacturer. My concerns is simple....how can the design of the fuel system allow the tank to collapse at all? my case resulted in pump hardware damage, but it seem very plausible that fuel tank damage or failure is very possible, potentially leading to spilled fuel and fire.

This morning I switched on my rear defroster. Outside temperature was around 50 degrees. With a few minutes I heard a loud pop. Inspecting the glass of the vehicle I found the driver's side rear window broken (spider webbed). The dealer is telling me that glass is not covered under the extended warranty.

On a ~50 degree morning, I turned on my rear defrost when my rear window (passenger side) shattered about 5 minutes after I turned it on. This is a 3 piece window as the middle is a slider on the pickup, only the passenger side broke. I was driving with no other cars around as there must be a short or faulty wiring in the rear defrost. This was not covered under warranty by Ford and seems to be a common problem.

- Sussex, WI, USA

Filed a complaint earlier in the year about the electrical problems, and finally received a call back from the dealer. I took my 2010 Ford F-150 in and it was determined the wiring harness was defective. Well great...900$ to get if fixed. Not covered under warranty. Truck will not start without it. Wow, I use to love Ford... never again will I purchase a Ford of any kind. Thanks.

The driver's side seat heater quit working after my wife complained about it "getting so hot it was literally burning her legs". I took apart the seat today to replace the heating pad because I had read about this being a common problem. To my surprise my wife was not exaggerating. There were burn marks on the foam insulation around a connecting piece of the bottom seat heater. My truck is out of warranty, otherwise I probably would've just dropped it off at the dealer and never witnessed this myself.

I had my truck parked outside during a heavy snowfall day at work. I went out and started it to let it warm up and turned on the rear defrost. When I got in to leave I noticed my passenger side rear window was shattered. I had no idea what had happened, not in an area where vandalism is possible. After reading the online posts about others with this problem I realized this is exactly what happened.

- Red Cliff, CO, USA

2010 Ford F-150. Outside temperature approximately 28 degrees. Started vehicle and turned on rear window defroster. Drove about 1 mile and was waiting alone stopped at a light. Heard very loud bang noise consistent to a crash or muffled small caliber bullet being fired. Stepped out of my vehicle to confirm I was alone on road and wasn't in an accident. (I was completely alone at 6am with no other cars in site). I noticed the right (passenger) side rear window had spider webbed and completed shattered. Rear window is 3 panes, right middle, left. Right side window that shattered was extremely hot to the touch compared to middle and left (driver) side. Contacting Ford as I believe this to be a manufactures defect as it has happened to many 2010 F150S with tri rear windows.
