Honda, Mazda and Nissan are recalling millions of cars ... for defective airbags that could possibly explode. The recall comes on the heels of numerous callbacks from Toyota and GM in recent months ... also for airbags and ignition failures. Jack Nerad, Vice President of Kelly Bluebook, says millions of car owners are suffering from recall fatigue. "They're driving, their car seems to be operating fine, and you know, people are busy. Probably visiting a car dealership service department isn't number one on their list of fun things to do" says Nerad, who believes recall fatigue is something the National Highway Traffic Safety Administration is concerned about and something the manufacturers are concerned about too.
