2016 Chevrolet Sonic LS 4 Cyl 1.80L
Evap Purge Solenoid Replacement
This is actually a 2017 with 42,000 miles, Never heard of this issue with having to replace Evap Solenoid and valve which was making car feel like it will shut down at a stop. They said a crack in vacuum.
Sounds like a question for the local GM dealerships in your area.
