Air Bag Light On problems of the 2012 Chevrolet Equinox

I have been having an issue with fumes coming into the cab of my vehicle through the front vents when set to defroster or circulating air from outside to inside through the vents. The fumes smell of gas or exhaust and are very noticeable when sitting still while engine is running. This is noticeable mainly when sitting still in vehicle with engine running. The smell is overwhelming. I have developed breathing problems since purchasing my vehicle. I have been newly diagnosed with asthma and am having to take breathing treatments. I had the first asthma attack in December 2019. I am also having problem with airbag light staying on. Wheel information is also incorrect. Information system may indicate the front passenger wheel pressure is low, when in fact the rear passenger tire pressure is low.

Air bag light on dashboard is on (not flashing). Service airbag message on message display. Not caused by accident. No airbag deployment.

The contact owns a 2012 Chevrolet Equinox. While the vehicle was stationary, the air bag light illuminated without warning. The issue recurred while driving 35 mph. The vehicle was taken to be repaired. The manufacturer was not made aware of the issue. The failure mileage was 30,700.
