"One of the driver-side seatbelt assembly bolts may not be properly tightened," said NHTSA in its recall summary. "An insufficiently torqued bolt may prevent the seatbelt from holding the required load in a crash, increasing the risk of injury."
A GM spokesman did not respond immediately to a query from Edmunds asking if there are any injuries, crashes or fatalities linked to the recall.
The affected Cruze sedans were built from September 24, 2014 to May 29, 2015.
The problem was discovered during an internal test at GM's Lordstown, Ohio assembly plant, the automaker told federal safety regulators.
The tool used to fasten the affected seatbelts was reprogrammed to ensure an alarm would sound if any of the affected bolts were not fully torqued, according to a GM document filed with NHTSA.
Edmunds says: No parts are required for this repair, GM says. Owners of these vehicles should be in contact with their Chevrolet dealer on next steps.
