ELECTRICAL SYSTEM
I was driving down the road after turning on the rear window defrost. The cab of the truck filled with smoke billowing from the back seat. I pulled over and turned the truck off. I got into the back seat to try to identify what was on fire, and noticed the lines of the rear window defrost system were actually smoldering. Then one of the rear windshield panels exploded in my face. Upon reading online, it looks like a recall was issued for this same problem in Canada but not the USA.

STRUCTURE:BODY
This truck has a 5 star crash rating, but is rusting very badly due to a defect in the design of the truck. There are tracks in the roof that lead down behind the cab. The water rolls down and then there is an indentation that holds the water. This water holding creates rust, horrible rust. The rockers, frame and the fuel pump rusted badly due to this defect. The 5 star crash rating comes into huge doubt due to such rust from the design defect.

POWER TRAIN
When I first start the truck up and reverse out of my driveway once I shift it to drive it hesitates and feels as the transmission slips from 1st to 2nd gear. Makes it a safety issue due to the truck launching forward once the acceleration kicks in and the revolutions are high once the truck starts its speed from the hesitation.

SERVICE BRAKES
The trailer brake system has stopped working and displays the message "Service trailer Brakes" it does this no matter if several different tralers are hooked to the truck. These trialers test fine in other trucks and with meters. The trailer brake controller does not work. There are many owners reporting the same thing. It is a critical safety feature to stop the truck & trailer and probably already has led to some fatalities. Please issue a recall. Thank You.

My vehicle shakes at different speeds. Do to the admitted mistake that GM said certain assembly lines put the wrong Transmission fluid which causes corrosion to Transmission. Im paying $900 to correct the problem. They should have recalled the vehicles that was affected.

STEERING
The power steering failed on three different occasions, all while making a low speed turns. Two of the times it was only a matter of a half a second or so, but the most recent time it failed and I couldn't steer my truck at all and I almost got in an accident. I needed to come to a complete stop, and put my vehicle in park, the power steering warning light had came on. After I stopped, it was another 5-10 seconds before the warning light went off and the steering returned.

SERVICE BRAKES
I'm having problems with my low speed braking. When I am breaking at low speed such as at a stop sign or parking, it's like the pedal stops working, gets stiff, and I have to brake very hard to get it to work. This is of great concern to me as a safety hazard. Unable to stop in a parking structure or at a stop sign/signal can be fatal and this needs to be addressed and dealt with immediately.
