Getting a 2003 kia sorento to start after hitting a tree and the airbags deploy

What is the reason for the deployment of the airbags , did you hit the car or they open with no reason. If you hit the car there is fail safe mechanism to stop the engine automatically.

The sensor is usually encased in a pnuematic piston located in the front bumper. You ran over a curb? You hit the bumper, it deployed.

They didn't deploy cause you hit a deer, the airbags sensors need to get a gforce reading to deploy, hitting a deer ksnt enough to do it

I does not take much to wrinkle the steel. And vehicles are built with impact zones that are designed to crumble in order to absorb an impact.
Also hitting a tree, as long as there was no give, the air bags should deploy if you were doing 15mph+. If you hit a movable object like rear end a car it would be more like 30mph. But is not an exact science either. Say you were doing 30mph when you hit the tree. Did you brake just before impact? The speed would have been reduced by the time you hit the tree.

Then look at how that truck is built. Its a tin can. Its much less sturdy up front because it is a body on a frame. A uni-body would be stronger up front that that Toyota. The bumper is near nothing, not much of a radiator support, weak aprons. They just are not built like a Tonka truck. With all that stuff giving in there may not have been enough energy left to trigger both impact sensors.

There should be at least two sensors. One up front and one inside the cab (the cab sensor may be inside the airbag brain). Both sensors need to be triggered to activate the air bag. Also the impact needs to be from a straight head on to about a 30 degree angle left or right.

I have worked on a lot of Toyota trucks (fleet vehicles/delivery) over the years in the body shop. I have seen how weak they are up front and how easily they will bend.
"Oh what a feeling.....Toyota"

It all depends on the speed you hit tree. BMW can scan computer and track back any faults. Hopefully SRS/check engine light wasn't lit when you were involved in accident.

in the U.S. the airbags are programmed to deploy @ 9mph(roughly the same as hitting a kerb hard.)so if the airbag went off you would not know if you hit a pothole, unless you went back to look....dont know any makers airbags that have recalls applied to them.
think of the litigation if there were...........

check airbag connects and have code cleared should go out

it could be several different reasons for your oil leak but the damage is done id suggest installing a used engine i run a auto repair shop i could probably locate a used engine for you contact me if your interested 704-922-8880

check in the trunk on one of the sides there should be a switch if thats not it check the starter it might have got banged when you went off the road

Have look at the tyre if you could see any bulges or have a look at the rim on the edge for any damage
