When driving it sometimes begins to hesitate reduce power the traction and stability and engine light comes on. When this happens the RPM gauge as well stops working. If I pull over on side of road and turn off and restart most times the ignition will hang and keep trying crank the vehicle. It's hesitant to crank when this happens and sometimes cranks and then immediately dies. It will shift hard just before powering into a reduced power mode. If you turn off restart turn your wheel all the way left and then all the way right and crank it will sometimes make the lights go off and you think reset but as soon as you start driving it happens again. I understand this is a problem a lot and I mean a lot are having so not sure why this isn't being investigated and recalled. Most say no matter what they have repaired or replace the problem still exist so there is a root that's creating the problem that needs to be found and addressed by General Motors! forgot to mention when this happens sometimes the brake pedal as well gets really hard! this a problem that's been continuous off and on since I've owned the vehicle.

When pressing down on accelerator to get into traffic flow something sticks so that the engine runs at high speed until you kick the pedal two or three times to release what ever is sticking. Has happened multiple times.
