Is the sound coming from under the hood or under the vehicle? If so, the most common cause is a loose heat shield on the exhaust system.
Do me a favor. Take something like a rubber mallet and tap on the exhaust to see if you can recreate the sound. If you can, have a helper tap on it while you locate where it is coming from.
Heat shields are welded in place. The welds break and then they rattle. These shields are normally around the catalytic converters and mufflers. If you can, record it and upload it for me to hear. I should be able to tell you if that is the issue.
