Is the check engine light on? If so, the vehicle will start and then shut off.
As mentioned before ensure that the rear gate is latching and locking correctly, although if the door doesn't lock the remote start should not start the vehicle at all. If it started after an accident my advice is to call you insurance company and report it to them. They should direct you to a dealer or approved repair shop and it should all get rolled into the insurance claim for the repairs after the accident.

Thank you all and i highly appreciate your concern.
Danger Aaron, yes the check engine light is on. I will try to turn it off and try again. Thank you all again.

The check engine light is certainly an issue. Resolve it and then see if your remote start works again. I had an issue with the intake runners that turned on my check engine light and the remote start would do exactly as you say. It would start, but only run for about 10 seconds and then shut off. I fixed my intake runner issue and the remote start functions normally.
