Hello Donaldjlim,

Sorry to hear you're having this issue. Have you been to your Chevy dealership for this issue? Because I am not a Certified technician. I would recommend having your GM dealership properly diagnose what's causing your car to jerk. If you would like for me to research your VIN, to see if there are any special coverages or open recalls, I would be glad to do so.

Keep me posted on how it goes.
