Violent and erratic shifting during acceleration and deceleration. . . A simultaneous pop and jerk happens. . . Also when accelerating and hitting passing gear the truck seems to stall out and then quickly engages to apply more power than expected. . . This can be dangerous for a driver attempting to merge onto highways/highways! the jerking occurs on a regular basis and at various speeds on various highways. . .
The vehicle is stalling when braking and getting ready to turn. My truck is showing stabilitrak service intermittently and I've almost been in a crash 3 times because of this. The vehicle only restarts after placing in park. This is not safe when in traffic. There seems to be no recalls and no known cause. Someone is going to die if gm doesn't fix this. I've been on forums and it's a common problem. It should be fixed by gm if it is so common. This happens when approaching cross traffic at an intersection and I lose all control of steering braking and power to the truck.
