Air bags: Fiat Chrysler recalls 1.9 million cars

Fiat Chrysler now recalling 1.9 million vehicles worldwide.

A possible defect in their air bags linked to three deaths and five injuries.

Last week, General Motors announced a recall of 4.3 million - for a similar but not identical fault.

"The issues with regard to legal actions have meant that even the slightest concerns means that you are going to get these recalls occurring. This is becoming increasingly expensive, so frankly whether it's Fiat Chrysler or anybody else, it just means that there are going to be more of these occurring because no-one has developed a car which is without any particular future failure."

In May, U.S. officials said car makers would be recalling another 35 to 40 million Takata air bag inflators that could rupture and send deadly metal fragments flying.

More than 100 million inflators worldwide have been deemed defective - and are linked to at least 14 deaths and over 100 injuries.

Consumers, though, have been slow to react to the widening problem - for now.

"For Chrysler Fiat, along with some of these others, it's almost seen as 'oh, it's another one of those car companies.' If however you get labelled as being the car company that is consistently doing this, then you will have a problem. So that what you've got to make sure, is to make sure that it can happen once, maybe twice, but do not make it a regular event." A U.S. senate committee said in June that major manufacturers are continuing to sell vehicles with faulty air bags that will eventually have to be recalled.
