Power steering hard to turn at low speeds and backing up and cluster gauges go dim then back to normal

Power steering goes out and at time turn truck power off whenever i attempt a slow tight turn like backing into my driveway or making tight turns going into parking lots and/or spaces. Most recently, when attempting a u-turn at a busy intersection, power steering went out and engine died. I had to coast to the side to avoid moving traffic. Each time this issue happens i hear 3 dings all my dash & screen lights flash off then on with clicking noises. Dash info changes from speedometer to radio setting. If i look at screen quickly enough when this happens i would sometimes read “rear parking assist unavailable” or something like that. If air conditioning is on it would turn off then on. Doors will unlock then lock, all this happening simaltaneously while attempting to make a turn

Brakes do not work under slow speeds. Pumping breaks at slow speeds (parking lot speeds) causes break pedal to stiffen and the vehicle's breaks are not responsive. When this happens, I feel what seems to be ABS engaging (break pedal pulsates). The pulsating is only noticable in the break pedal. This behavior seems more prevalent in inclement weather.

The contact owns a 2015 GMC Sierra. The contact stated that while driving in stop and go traffic and attempting to depress the brake pedal, the vehicle failed to stop as anticipated instead the vehicle slid into the vehicle in front of them. The brake pedal began to vibrate and a skipping. The vehicle ended up crashing into the rear of the vehicle in front. The air bags did not deploy. A police report was filed. There were no injuries and no medical attention was needed. The vehicle was not towed. The contact took the vehicle to the dealer who were unable to identify the cause for the failure. The vehicle's alternator shocks, braking pump lines, and updated the computer system however, the failure persisted. The contact stated that whenever the brake pedal was depressed several electrical issues would occur like with the navigation screen and all windows would shut off. There were many warning lights including the air bag and stability control. The manufacturer was made aware of the failure. The approximate failure mileage 80,000.

I have noticed over the last few weeks I am losing radiator fluid. Its slow but noticeable. Engine temperature rises and fan stays on. My 2015 GMC Sierra 1500 only has 50,150 miles on it, and started well under 50,000. It looks like the leak is from upper contact points of Radiator and frame. I have come to find out that GMC has put a notice out on this issue and put a recall/repair out on the 2014 GMC Sierra 1500 for the same issue. Its a know defect. ( I WILL ATTACH COPIES ) I went to the dealer and was told they would fix the 2014 but have not issued a fix for the 2015. "Not enough complaints"? Its a very expensive fix for a KNOWN manufactured defect but GMC (AND CHEVY TRUCKS) want more complaints.... so here is my filing. Kind of a silly game they are playing when they know it should be a recall issue.
