NHTSA Complaint #11486113 — 2019 CHEVROLET EQUINOX

I've taken my car to the Springfield chevy dealership at 840 Baltimore Pike, Springfield, PA 19064 several time. The time the replaced mass airflow sensor had to be replaced or the oxygen sensor last year. I received a message from Onstar An issue with the emissions system in your 2019 Chevrolet Equinox has been detected. Please service your vehicle within 7 days. Which was the same message for berfore, Wayne the techn stated it the battery which is incorrect I informed him of the Onstar message and told him how the car would shut-off and wouldn't start. I had two battery test perform and was told the battery, starter and charging system all passed. He stated we have to change the battery as a starting point and work from there which is ridiculous. I stated if this is so why wasn't this mention in the Onstar Diagnostic Alert. My car was there for six hour and no one call I had to contact them around 4pm and they close at 4:30pm no customer service.
