First and most importantly my brakes are my main issue and safety problem. I nearly ran into the car in front of me at a busy intersection. My trucks brakes lose pressure after the first initial stop coming to any traffic lights, stop sign, slow traffic, parking lots etc... no matter how slow or fast the trucks movement is. First break attempt is ok but 2nd starts losing pressure and 3rd attempt is complete lost of pressure anf and the truck just rolls until it slowly comes to a stop. I worry about the safety of myself and others motorist regarding this issue. My second complaint is my driver side mirror. Every time I get into my truck and start it. My driver side mirror moves out of its setting and I constantly have to fix it.

After using the remote starter while vehicle was parked in my driveway, I started to drive my grandson to school. A short distance from home smoke and sparks started to emit from the rear seat next to the sliding window and electric rear window defroster. As I pulled over the rear window panel on the passenger side burst. I assume from excessive heat generated by the rear window defroster.

My windshield wiper fluid only sprays out 30% of the time. Usually in the morning then any other time of the day it will not spray out. They replaced the pump and that did not fix it and they won't do anything else and now it is out of warranty. When running lower rpms driving the truck it begins to feel like its shaking forward and backwards, like a shuddering feeling. I have read about other people having this problem and it describes mine perfectly. I have the 8speed
