1) it's highly flammable
2) it's very expensive to obtain
3) it's difficult to transport
4) imagine how large the fuel tank on your car would be
5) it's hard to keep it liquified or at high pressures
6) the slightest bit of static electricity will be deadly

Storage is a primary issue, most technology has focused on compressing the gas as a means of storage, or course, a leak could cause a rather nasty explosion. One reason traditional storage is an issue is that hydrogen is the smallest atom and can easily squeeze between other atoms and molecules that make up most storage vessels. Over time, your fuel could leak out.
However, at least one company has found a way to get by that problem by storing hydrogen in a metal hydride. Other companies have begun to focus variations of a sort of hydrogen matrix that traps the atoms in novel ways.
The other problem with hydrogen as a fuel is that there is no infrastructure to support it currently. This will likely follow supply and demand, when people finally start demanding hydrogen cars, the supply will eventually come with it.
A final problem is that if hydrogen is used in combustion engines, versus say fuel cells, many engines have to be modified to withstand the excess water that hydrogen combustion gives off as compared to petrol based combustion processes.

(1) Since it is the lightest gas, stringent storage and dispensing devices will have to be devised.
(2) Whether the cost of producing the gas justifies the expense.

Very explosive.
Expensive.
Your car might start floating off planet Earth if you put too much hydrogen in it.
"Mom, I just filled the car up with hydrogen!" Woops, too late, goodbye!!!

It is highly flammable...look at the Hindenburg disaster as an exampe

One problem is that it is hard to safely use. It explodes readily if the conditions are right.

It's not very safe. Oh the humanity!
