General Motors is recalling more than 400,000 pickup trucks in the U.S. because the side airbags can explode without warning.
The recalls are from 2015 and 2016 Chevrolet and GMC Sierra 1500, 2500, and 3500 trucks.
Documents posted Friday by U.S. safety regulators say the airbag inflator can rupture or the end cap can fly off on both sides of the trucks.
GM says a manufacturing defect allowed moisture into the inflator during manufacturing, causing corrosion, but no injuries have been reported.
Dealers will replace both side airbag modules. GM says it has a limited number of replacement parts available.
Owners will be notified by mid Aug. 16, and will get another letter when more parts for the replacement become available.
