What 1,362 owners told NHTSA about the 2014 Ford F-150 Supercab

Turned on rear window and heated mirror defrost. Rear window cracked loudly and broke in a spiderwebbed manner after about 10-15 minutes of the defrost being turned on. Tempered glass kept it from blowing completely out. May have caused injury if a passenger had been sitting in rear crew cab seat at the time. Spoke with Safelite auto glass repair, was told they see this frequently with F150 trucks and think there is a problem with defrost function not shutting off like it should, causing excessive heat to window which eventually breaks the glass.

Rear glass shattered spontaneously. There are many reports of this issue over a wide range of model years and no acknowledgement from Ford. Vehicle was parked with engine running and rear defrost on, no prior damage to the rear window. The drivers side rear glass shattered suddenly with a loud bang and rained small glass slivers down on rear occupants. Was quoted $1080 by a glass installer for replacement. They said this is a common issue with these trucks.

Back passenger side small window (one of three across the back, with a sliding center) spontaneously shattered tonight. It’s in the upper 30s and nothing hit it. I had just started the vehicle and began to move when two of my daughters and I heard a loud sound. My daughter said the window shattered. It’s still altogether but is spidered all over. There’s no evidence of anything hitting the window inside or out. Weirdest thing. I looked online and it seems this has happened to a lot of ford truck owners. The speculation is the rear defrost over heating. But I think since I saw so many online that had the same thing happen to them, I wanted to file a complaint. Ford should be replacing these windows. Obviously it’s a manufacture defect. Thanks.

Rear window on left side shattered on its own, Believe the rear defrost controller is to be be the issue, or faulty glass.

Tonight I was using my rear defrost on my F-150 and I noticed the glass looked weird. Got out and my worst fear was true the back glass had shattered. I have only owned this truck since April I'm the second owner.

2014 F150 Lariat owned since it was new. Windshield wipers failed to come on during Florida thunderstorm while driving on I-10 Westbound from Jacksonville Florida. Was totally unable to see out of the windshield and had to pull over until the rainstorm subsided. Checked all relevant fuses and relays and wiper switch. Nothing so far has been able to fix this Safety Defect. Ford knows the part is defective because the Windshield wiper motor is not available from Ford or any dealer, and there is no expectation by the dealer than anything will ever be available to fix this Safety Defect.

The rear defrost functionality has stopped on my 2014 F150 with sliding rear window. This causes visibility issues in certain weather conditions.

Truck has the heated 3 piece power rear window. I used the remote start on the truck while parked in an open detached garage while outdoor temperature was +5 degrees Fahrenheit. After approximately 10 minutes of warmup time I approached the truck and the driver side section of the glass made a exploding sound. The window stayed in place but was shattered into thousands of small pieces. It only takes a few moments of internet searching to easily see that this is a know problem that has happened to over a thousand Ford F150 owners of simular years to mine 2014. When "remote start" is used the Rear Window defrost system automatically engages. There is a manufacturing or design flaw in the window or defrost control system on these Trucks. I was visiting my Mother in Wauwatosa WI 53226 when this incident occurred.

During commute to work this morning I heard what sounded like a rock hit the top of my truck. Seemed strange since I was on Highway 101 and not under anything. Later I noticed that the rear window on the driver’s side was spidered completely throughout. Internet search suggested this was just one of many times Ford F-150 trucks have had this happen, but no recall has been issued. Not happy as this repair will be approximately $750 of my hard earned money Had I been transporting one of my family members in the back it could have been worse.

I have researched this problem of the rear window defroster not working and the rear window exploding. There are several hundred cases of this but nothing has been done. Ford has not been receptive to fix this issue and I think it is time to hold them accountable. They will offer to replace the window at over $1200. This is something that should be a safety concern since you really can't clean this without getting into the bed of the truck which is dangerous especially in winter time. This also affects the side mirrors. I am quite fed up with these companies not being held accountable.

The contact owns a 2014 Ford F-150. The contact stated that after her husband activated the defroster, it caused the rear windshield to shatter. The local dealer and several other dealers were made aware of the failure. All the dealers informed the contact to take the vehicle to an auto-glass dealer to replace the windshield. The vehicle was not diagnosed or repaired. The manufacturer was made aware of the failure and informed the contact that there was no recall associated with the VIN. The failure mileage was approximately 140,000.

I was driving with my defrost on front and rear windows at night time. I was stopped at a light when I heard a loud bang followed by a crackling noise. I safely found a spot to park close by and inspected if anything hit my truck. Nothing. My rear window on my cab was completely shattered. No evidence of anything hitting it. My truck bed was completely empty and had the canopy on. There was nothing in between the rear truck and canopy. What the heck? Had to be the rear defrost. There are multiple stories on the internet just like mine, with zero recall!!!! Ford make this right. Now I’m out 780.00 due to Fords faulty defrost wiring.
