VISIBILITY/WIPER
When operating my truck two days ago, I smelled something burning. I then noticed a small plume of white smoke coming from the rear driver's side window area. I then noticed my rear defroster was on, which I shut of right of way. About 30 seconds later, I heard a loud pop and I noticed the rear driver's side portion of the window was shattered. I brought my truck to the dealership and they said they could not figure out what happened. I believe it is tied to a prior recall, but they said my truck was found not to have any issues at that time. I believe there is a direct correlation with the recall issued and what happened a couple of days ago.

My rear back heated window on the passenger side popped and shattered the window while I was sitting in the passenger’s seat waiting for my husband. The truck smelled like a sweet wire smell and then I heard a loud pop. I looked back and the back window panel was shattered. I do see that there were recalls on some of these windows.

SERVICE BRAKES
While driving parking lot speeds, when I pressed the brake pedal, it was very very difficult to push causing me to nearly rear end the car in front of me. This happened intermittently during a short time frame (5 minutes). While standing on the brake pedal hoping to stop in time, the brake pedal shook like the Antilock brakes were activating. This caused it to be even more difficult to stop in time. My vehicle is currently at my local dealership's service shop. When the issue occurred, a message stating "Service Brake Assist" popped up in my display.

VISIBILITY/WIPER
Both the outside mirrors are loose and will fold while driving. At night if I am not aware and it is dark the mirror fails to identify vehicles in the visibility area because they vibrate closed to the door from the driving air on the mirror. I will have to pull over and push the mirror back. I have brought it to the dealer and they say they all do it. It is normal. The issues has been confirmed by the dealer. It has been present on the car for about 1 year. The internet is filled with this safety complaint. They are starting to fold when you close the door.
