The iconic postal truck may have outlived its time, as videos of the trucks bursting into flames continue to surface across the country.

There are dozens of media reports about engines exploding as letter carriers are out making their deliveries. Witnesses said the same thing happened in a Chicago suburb of Sauk Village.

“By the time I looked out the window it was engulfed in flames,” Quinta Echols, a witness, said.

Luckily, fire crews in Sauk Village were there within minutes. But it turns out fires like this have happened dozens of times across the country in the last few years.

Mack Julion with the National Association of Letter Carriers union knows all about it.

“We’ve been made aware of these vehicles,” Julion said. “That’s why we are engaged with the postal service in dialogue to make sure they are safe.”

It’s no secret the United States Postal Service has been tackling financial problems for years. This is another issue that will likely to cost millions of dollars to fix. More at WGN TV Chicago
