Can you get your leased car out of repossession?

It's not really clear what you mean by "out of repossession". Repossession is an event, not a condition. If you're asking if you can get it back after it's been repossessed, it's at least theoretically possible if you act quickly enough; you should contact the leasing agency and find out what you need to do. At minimum, you should expect to have to bring the payments current and pay the repossession expenses; you may also be asked to provide a deposit against future defaults.
