A door that bounces back open or only latches if you slam it hard usually has a stuck latch or a misaligned striker. Less often it is a dropped door from worn hinges. Here is the ranked diagnosis.

The fork inside the latch is jammed in the closed position (or partially closed). Common after the door is slammed with the latch in the locked position. Manually toggle the latch with a screwdriver to reset it. Cost: $0 - $50. DIY: Easy. Severity: Medium.
Get a Free AI Diagnosis →The bolt on the door pillar (the "U" the latch grabs) has shifted or worn. Door catches on first latch but bounces off final latch. Re-aim the striker with a wrench so the door pulls closed flush. Cost: $0 - $80. DIY: Easy. Severity: Medium.
Get a Free AI Diagnosis →After 150,000+ miles or years of heavy use, hinges wear and the door sags downward. Striker no longer lines up. Visible by lifting the door at the outer edge - if it moves up more than 1/4 inch, the hinges are worn. Cost: $150 - $500. DIY: Hard. Severity: Medium.

Get a Free AI Diagnosis →The metal arm that limits door swing breaks. Door swings too far and the inside handle catches in the open position, holding the latch open. Visible as a door that swings past its normal stop. Cost: $60 - $200. DIY: Medium. Severity: Medium.

Open the door and look at the latch on the door edge. The fork should be open (in the "ready to catch" position). If it is closed (clamped on nothing), use a flathead screwdriver to pull the spring-loaded release. Latch should snap open. Now try closing the door.
Look at the U-shaped bolt on the body pillar where the door latches. Marks on the rubber boot tell you where the latch is hitting. If marks are off-center, loosen the two Torx or hex bolts holding the striker, tap it 1-2mm in the needed direction, and re-tighten. Test the door close.
Open the door 90 degrees. Lift the outer edge with one hand. If it moves up more than 1/4 inch before the latch contacts the striker, the hinges are worn. Hinge replacement requires a body shop; striker shimming can buy time.
Spray white lithium grease into the latch and onto the striker. Cycle the door 10 times. Sticky latches account for half the "door wont close" cases and a $5 can of grease fixes them.
If your scanner shows one of these B-codes (body) along with the symptom, run a free AI diagnosis to confirm.

Either the latch is stuck in the closed position (use a screwdriver to release it) or the striker on the body is misaligned so the latch never reaches the final catch.
No - it can fly open in a turn or accident, and on most modern cars the "door ajar" warning will keep the dome light on and drain the battery. Use bungee cords or get it towed.
A new latch assembly costs $40 - $150 in parts plus 1-2 hours of labor. A misaligned striker is free to fix yourself.
Sticky latch. The fork sometimes returns to the open position and catches, sometimes does not. Lubricating the latch is the fix.
Yes. Hinge pins and bushings are the cheaper repair ($150 - $300). Full hinge replacement is rare and runs $400 - $800.
Either the latch is not fully closed (visible as a small gap) or the latch switch inside is bad and reads "open" all the time. The latch switch is part of the latch assembly.
