Federal safety regulators are warning owners of more than 4.7 million vehicles to get their recalled air bags repaired immediately.

The National Highway Traffic Safety Administration issued the warning Monday, because air bags made by Takata Corporation can rupture, causing metal fragments to fly out when the airbags inflate in crashes.

Experts said this is a recall you really want to listen to, because these airbags can be a ticking time bomb.

“You don’t have to have a vehicle that’s been in a flood or anything like that,” said Larry Perry, the president of Magic Mechanic, Inc. “It’s just the natural occurrence of heat and cold. Condensation collects in this explosive charge and when this takes place and deploys, it’s heating up. It’s almost like you took a torch to a piece of metal and just made it molten lava, and so when it comes projecting out of this air bag, hopefully it doesn’t hit you if it was to happen.”

Safety regulators said at least four people have died from the program.

However, local mechanics believe there will be a waiting list to get recalled air bags replaced.

Some of the cars on the list are up to 14 years old, which means new air bags for those models have not been manufactured in years.

The inflators have led to multiple recalls from manufacturers like Honda, Mazda, Nissan, General Motors, Mitsubishi, Ford, Chrysler, BMW and Toyota.
