As noted in previous statements this vehicle is difficulty at starting and cranking at various situation. Playing the radio with engine off, must wait ten minutes before attempting to start, then it may crank or you have to start over. Its not the radio its the ignition lock cylinder as done in the past. It doesn't matter, stop, or moving it has done all you mention, and with the lights off at night you can injured a pedestrian or ourselves. This car was recall and it was said to have been fix but here we stuck here from 04/07/17 possibly will get help from the nearest GMC car dealer on 04/10/17. Keep all this information for official used only. Thanks updated 05/17/17 updated 07/25/2017

In a hard stop in stop-and-go rush hour freeway traffic, a corroded steel hydraulic brake line failed. This was the line from the ABS module to the right front brake. As such it immediately caused a substantial loss of braking ability - I was in the far left lane and I was able to abruptly move to the left shoulder. Had I been in one of the center lanes there would have been a crash, it would have been unavoidable, the rear brakes were still functional and I still had limited braking ability. At the point that this line actually broke, it was spraying brake fluid directly on the exhaust system. I am not certain whether there was a fire, the mechanic says there may have been. There certainly was a lot of smoke. The line in question is secured to the firewall and is routed close to the exhaust at that point. It appears that over time this combination allows corrosion to weaken the line at this particular point. The remaining lines on this vehicle are in good condition and I believe they will last the life of the vehicle.
