Cam and Alternator Belts Breakage

Hi,



Recently, both the Cam and Alternator belts in my car broke.

The car is only 6 years old and has done just under 53,000 miles, so well under the advisable time/mileage to change these belts.

Anyone had this happening to you?



Any ideas as to why this may happen prematurely and what causes it?




Thanks.


Cheers

What kind of car?

It was a Ford Mondeo.

Does it matter the type of car?
