The warning indicator coming on could be due to a faulty sending unit. Test for overheating, which could be due to bad cooling fans or partially clogged radiator.
The alarm going off could be due to bad door switches or doors out of adjustment.
Check the warning indicator on dash for signs of doors not closed properly.
Turn the dome light to operate when the doors are opened. Close all doors and while seated inside the car, push at each door panel and note if the dome light comes on.
If none, check the hood switch.
