Ignition Switch Problems of GMC Sierra 1500

Issue #1-while driving the vehicle stablitrak warning light, traction control, engine power reduced, and brake light all came on. Vehicles engine power was suddenly reduced to about 10 mph while driving on the interstate in which I found to be very dangerous! had to pull over, turned off vehicle, lights went off, started driving again, vehicle did the same thing. Had to take in for mechanical repairs. Issue #2- key ignition switch just started locking up on the vehicle, would not turn back to normal to position, had to repeatedly keep jiggling for over 30 minutes or so to get the vehicle started back up?? had to take vehicle to dealer for repairs also. These are very unsafe and costly issues that GMC should be mandatorily required to have recalled and immediately addressed for the safety of the general public!!.

The problem is with the electrical system: ignition switch, when I insert the key in the ignition, it won't turn, it bind, its stock, very hard to turn.

While driving on a street in my neighborhood, we found that the ignition switch could be moved to the "off" or "accessory" position while driving. Noticed that steering, brakes, and other components became disabled. Luckily we were able to safely move the vehicle to the roadside and assess the situation. A problem like this could result in catastrophic system failure in the vehicle while driving at high speeds, and could cause possible death if we weren't aware of this problem. Please inform other vehicle owners of this possible dangerous issue.
