Audi is recalling nearly 102,000 luxury cars in the U.S. because the front air bags may not inflate in a crash.
The recall covers certain A4 and S4 cars from the 2013 through 2015 model years, plus the 2013 through 2015 Audi allroad.
Audi says that it is part of a wider global recall that the company announced last week covering about 850,000 vehicles from the 2013 to 2015 model years.
Dealers will update an improperly programmed air bag control module to fix the problem sometime this month.
Audi said that in rare cases the air bags may not inflate in a secondary impact. That can increase the risk of injury.
No crashes or injuries have been reported in the U.S. or Europe, an Audi spokesman said. But the company is checking a small number of cases in Europe to see if they are linked to air bag programming.
The company said in documents posted by U.S. safety regulators that the problem was discovered in tests done in August.
