Chevrolet Repair Questions? Ask a Chevy Mechanic for Answers ASAP
Sounds like a similar issue to Chevy Cruze.
I would check, clean and tighten all the body ground points, 5 in total.
I would also have all the modules checked for current software.
Only a dealer can do the software check unfortunately.
Do you need any further help?
I hope my advice has been of assistance to you.
