If they have a doghouse, making it warm and inviting might convince them to stay there instead of hopping onto a (presumably) warm car. maybe they're trying to tell you they're cold?
Also, are you letting the dogs run free? That's inadvisable, illegal in the city, and dangerous in the farmland/country/forest. We've had a neighbor lose a dog a few years back to a beast. We are in the borderline farmland between city and forest. things come down from the mountains and eat what they find available, including dogs and cats. We get bear, coyote, mountain lions, racoons (yes, they are dangerous), eagles, buzzards and bobcats.
We are in the NW, but it can happen anywhere. There was a mystery beast eating dogs in the south, and after some work it was discovered to be a puma who was roaming a nearly 200 mile area who'd decided dog was easy to catch and good to eat. It was killing some dogs that were bigger than it, Danes and Pits. Something to think about, and they do come down into populated areas. So don't let your dogs run loose, it isn't safe.
Do you have a key fob with a horn on it? Also, depending on how new or old you vehicle is, I might try putting flat cardboard boxes on the vehicle. This booby-trap will cause the dog to be suprised and limit success in climbing aboard. Just a couple of ideas to try. :)
