I was driving on a residential street with the rear defroster on. Snow and low temps were happening at the time. While driving it sounded like a gun shot went off. I checked my mirrors and rear view mirror and that's when I noticed the rear window drivers side was shattered. Thank god no one was sitting there. Upon some internet searching this is a well known event for F-150 and Ford still has done nothing about it.

Remote started my truck Saturday morning 2/3/2018 as I live in Iowa and it is cold this time of year. After about 10 minutes went out got in the truck turned it on and put it in reverse and started backing out of my driveway. When I heard a loud bang like a gunshot or someone dropping a cinder block on my roof. I got out and looked around to see if something had hit my truck and didn't see anything. I got back in looked out my rear window and the driver side rear window was shattered. You could tell that it wasn't hit because there was no focal point where someone or something would have made contact. The entire thing was shattered.

The windshield wiper fluid system gets frozen during 10 or below weather. I've tried using name brand wiper fluid rated for the winter and even adding more alcohol. Also tried cleaning out the nozzles and pouring warm water. Only thing that addresses it is parking the vehicle in a heated garage. Have taken it in for service and they replaced the fluid with their preferred brand and the same thing happened again. So this definitely is not an issue with the windshield wiper fluid or random circumstance of freezing nozzles. This is very dangerous during the winter as road salt and grime sprays on to the windshield and visibility drops.

The wiper control remains on even when in the off position. It will keep going on the slowest intermittent setting. This does not matter if you are stationary or moving. Numerous reports listed in online forums also.

The rear window defrost stopped working. 3 Ford dealerships indicated this is widespread with this vehicle. With snow sticking to the window, visibility for reversing to avoid other vehicles, obstacles and pedestrians is greatly reduced. A vehicle this large, even with rear camera and mirrors should have the best visibility possible.

Rear defroster was not working, I actually realized it when hitting the rear defrost on/off button by mistake. The service department told me that this is known and common problem with the F -150. I noticed the problem when I was a couple of months and 2000 miles out of warranty. (didn't need rear defrost for many months). I never needed my rear defroster during the summer in Michigan. I noticed this problem even before the first time I needed to use it in the fall. When I took it in the dealer led me to believe that Ford would pay for this because it was a known issue. Ford denied that it was a known issue and told me they would only cover part of the repair, leaving me with a $250 fee. The rear window defrosters on the F-150 are a safety hazard and can cause the rear window to explode if not replaced. The service team informed me that I was lucky that mine hadn't exploded. I only noticed it because my button on my instrument cluster didn't illuminate when I tied to use the rear window defroster. Ford Motor Company should be ashamed at the way they are hiding this known issue.
