Most car failures have a middle stage. Brakes get spongy before they fail, a battery cranks slowly before it dies, a bearing whines for months. The warning is the point.
A door latch has no middle stage. It holds the door closed or it does not, and the transition happens without notice.

Nearly one complaint in six describes the door coming open in motion. Not rattling, not failing to lock — open, at speed.
Why it fails the way it does
A latch is a spring-loaded claw that grips a striker bolt on the door pillar, with a secondary catch behind it to hold the door if the first one releases. It is a mechanism that operates several thousand times a year, in the weather, at the point where the body flexes most.
Two failure paths dominate. Corrosion stiffens the mechanism so the claw does not travel fully home — the door looks shut and is resting rather than latched. Or the linkage between the handle and the latch stretches, so the release stays partially pulled and the claw never fully engages.
Both produce a door that is closed at rest and unlatched under load. The load arrives at a corner, or over a bump, or when a passenger leans on the trim.
The warning signs nobody acts on
There are signs. They are just too mild to feel like anything.
A door that needs a firmer slam than it used to. A door ajar light that flickers on a rough surface and goes out again. A handle that feels slack, or a latch that does not click crisply when you operate it by hand with the door open.
Each of those individually reads as an old car being an old car. Together they describe a mechanism approaching the point where it stops holding.
Regulators treat latches seriously
One number puts the category in context. Comparing complaint volume against recall counts, latches and locks sit at about 15 complaints per recall — among the lowest ratios of any component group.
By contrast, engines run at 87 complaints per recall. The difference is not about how often things break; it is about how readily a regulator treats a given failure as a defect rather than as wear.
A latch that opens on the motorway is unambiguously a defect. An engine that fails at 140,000 miles is arguable. So latch problems convert into recalls at nearly six times the rate.
What to do
On a car you own, the check takes ten seconds per door. Open the door, operate the latch by hand, and watch the claw rotate and click home. If it feels gritty, sticks, or does not return crisply, it wants lubricant at minimum and inspection if that does not fix it.
On a car you are buying, close each door normally and listen. A door that needs to be slammed harder than its neighbours is telling you something about that latch specifically.
And because this category converts into recalls unusually often, it is worth checking whether a specific vehicle has an open campaign. A free VIN check lists them, and the repair costs nothing.
Frequently asked questions
How common are door latch failures?
12,401 complaints name latches, locks or linkages, with 605 injuries and 25 deaths recorded against them. Of those, 1,930 explicitly describe the failure happening while the vehicle was moving and 5,776 mention a door opening.
What causes a door to open while driving?
Usually a worn or corroded latch mechanism that no longer engages fully, or a linkage that has stretched so the door appears shut without the secondary catch holding. The door sits closed at rest and releases under the lateral load of a corner or a road undulation.
Is there a warning before a latch fails?
Rarely a useful one. The signs that do appear are a door that needs a firmer slam than it used to, a door ajar warning that flickers, or a latch that feels loose when operated by hand. None of them feels urgent, which is exactly why they get ignored.
Are latch problems ever recalled?
Frequently — latches are among the components with the lowest ratio of complaints to recalls, meaning regulators act on them comparatively quickly. That makes it worth checking whether a specific vehicle has an open campaign, because the repair is free and the failure mode is not one to gamble on.

703 Seat Complaints Involved a Fire. The Seat Wasn't the Problem.
Nobody expects the seat to be a fire risk. It burns more often than the fuel system does, for a reason that has nothing to do with what the seat is made of and everything to do with what was added to it.
Rust Complaints Fell 41%. The Ones Left Are Structural.
Bodywork corrosion largely stopped being the thing that kills cars. What replaced it is less visible and more expensive: rust in the places holding the suspension on.
One Petrol System Complaint in 23 Involves a Fire
Fuel system faults sound uniformly alarming. Split by which part of the system failed and the risk separates cleanly into two groups — and only one of them is about fire.
