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!!

Something is wrong with the electrical system. All my door locks repeatedly lock and unlock, all my emergency checks and service light go on and off, my gauges all drop to zero, and most recently my vehicle has shut down while I'm driving it. But it happens randomly. Sometimes it's worse than others. I recently had to steer up onto a curb because I was driving and my gauges dropped to zero and my engine completely cut out. And that was after my airbags shut off and my lights and door locks flickered repeatedly. Maybe there's a short in a circuit or wire or maybe it's my alternator but services at a dealership are having a difficult time finding it. And al these things happen whether I'm driving or stationary. Rain or dry. Doesn't matter. But it's clearly unsafe. And I have no choice but to drive it because it's my only means for transportation.

My starter or fly wheel is causing my truck to not want to start, also there is a rattling noise while driving at about 1500 RPM, and something is knocking in the rear of my truck. Its a 2011 with less than 40,000 miles and has been taken well care of, no reason this should happen. Luckily still under warranty.
