Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering seatbelts on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.
This informational bulletin provides information to advise dealers about seat belt buckles not operating and/or seat belt warning light illumination, as well as difficulty latching and unlatching the buckle or the buckle release button sticking.

The failure pattern owners describe
Owners consistently report six distinct seat belt problems in 2008 Cobalts. Front passenger retractors fail around 90,000 miles, triggering SERVICE AIRBAG warnings while refusing to engage—Chevy issued service bulletin #270624 but denied warranty coverage, forcing owners to pay for replacement. Driver-side retractors also fail with SERVICE SEATBELT warnings; repair quotes run $500–$650. Rear seat belts lock during retraction and won't release for 10–20 minutes, or sometimes won't deploy at all, making back seats unusable for years.
Buckles jam hard to engage or release; one passenger got stuck mid-buckle and required cutting free post-surgery. Front seat belt guides on coupes pinch the webbing when taller drivers sit back, leaving dangerous slack that won't properly restrain. One driver found webbing unraveled with the buckle held by a quarter of material. Dealers have treated rear belt failures as accessory repairs, billing for troubleshooting. Owners frequently cite multiple complaints online, suggesting Chevy knew about these issues but did not recall vehicles or cover repairs.
