GTA

A Glitch, or in some cases a Bug, is an error in the game that produces an effect that was unintended by programmers and appears in almost every game.

Description
The Glitches often arise from mistakes or errors in the game's coding which go unnoticed during development and testing of the game. Glitches can be unintentional and may cause problems to the player, but some glitches may be used to the player's advantage.

Some glitches are prominent than others and each one are specified and/or shared on a certain console (where these depends of the console's technical aspects). One of the most popular and common glitches is nicknamed "[Hell|Blue Hell]", which is featured in every game since GTA III. Once the player enters Blue Hell, they will fall for 5–10 seconds before returning to the surface.

Multiple Grand Theft Auto Games
While some glitches exist in multiple GTA games, this table lists all those glitches that exist in multiple GTA games.

Disappearing Vehicle Glitch
Occasionally in GTA LCS, the player may park a car somewhere and do something else (a mission for example), and the car won't despawn like normal; it will take a very long time to disappear. This only seems to happen on [Island|Staunton Island] and was tested in the [Portable|PSP] version. In GTA V, vehicles have been known to disappear from the player's garage after leaving them there, however the glitch seems to have been patched in subsequent versions. In GTA Online, the vehicle may disappear after entering and using and [|Ammunation] store; This happens the most often with helicopters.
 * The Disappearing Vehicle glitch is prevalent in all of the [Universe|3D Universe] games and occasionally in [Universe|HD Universe] games. If the player parks a car near any mission marker, and then walks into the marker to trigger the mission cutscene and starts the mission, there is a high chance that the vehicle they parked will have disappeared after the cutscene. This glitch occurs when the mission cutscene somehow interferes with the space taken up by the parked vehicle, so the game gets rid of the vehicle altogether. This glitch occurs occasionally in GTA III and GTA San Andreas, but it is very frequent in GTA Vice City, GTA Liberty City Stories and GTA Vice City Stories, where the vehicles the player takes to mission markers almost always disappear after the cutscene. GTA IV has a system implemented into it, where, instead of "getting rid" of the vehicle, the game just moves it somewhere else, like across the street or a few yards away from where the player left it, so it does not interfere with the cutscene.

If a large number of vehicles explode over the course of a few seconds, their burnt wrecks may disappear suddenly if they leave the player's line of sight. While this is considered a glitch, it is actually a game mechanic; the game engine de-spawns them so it doesn't have to process so many on-screen vehicles at once.

Car Spawn Glitch

 * In all of the 3-D Grand Theft Auto games, there is a specific glitch that occurs, in which the player is driving at a normal speed in any car on any road, and then looks behind when the "Look Back" button is pressed. When the button is released, and the camera returns to look forward, there will be several cars driving on the road in front of him that weren't there before the player initially looked back, and also de-spawning cars which were actually coming towards the player before (e.g. in the other lane). This happens because the game is designed to spawn cars wherever the camera isn't looking. If the player looks back, the game will spawn cars in front of them. Possibly because of a modified game engine, this glitch is not present in Grand Theft Auto V.

[Clumping|Car Clumping]

 * In most of the 3D and HD era games, there is a certain glitch in the game which causes many of the same car model to spawn together driving on the road. This glitch seems to be more prevalent in games that are heavily modded or with many cheats, as this may unintentionally alter the vehicle's spawn rates. A possible cause of this is the resource limiter being triggered especially if the vehicles are of higher quality than are intended for the game - in GTA IV this results in taxis being spawned as a fallback, while in 3D era games, streaming issues may also occur as a result of installing too many mods.

Double vehicle explosion

 * This is a common glitch in 3D era games. If a car is destroyed when the driver is still getting out of the car, the destroyed car will catch fire and explode again. This happens commonly if the player is using a high-powered weapon such as the minigun to destroy vehicles, because the driver has no time to fully get out of the vehicle when it starts to catch fire. This won't happen if only the passenger is getting out. This happens with motorbikes more often because the driver will fly off the bike as soon the bike explodes, and the bike will explode again. Vehicles will also explode twice if the player is in the middle of the getting out of the car animation when they explode.

Invincible Law Enforcement Agent
However the glitch in GTA CTW is quite rare to happen. It is unknown what kind of in-game factor makes this happen, although this was patched in GTA IV and GTA V for better gaming performance.
 * For some reasons, in most 3D Universe games and rarely in HD Universe games (but uncommon in GTA CTW), if an officer of a law enforcement opens the the player's vehicle's door, he will most likely become invincible of any type of damage, as if the protagonist shoots him nothing will happen rather than the opening door animation of the officer, and [|the player will be arrested] if they are too slow to escape. This happens frequently in GTA VC, GTA SA, GTA LCS and due to a glitch, in GTA Chinatown Wars.

Instant Non-Vehicular Arrest

 * If the player falls flat to the ground and just at that time a police officer comes up to the protagonist on foot while having a low wanted level, the cop will strangely do the arrest animation and the player is rendered as "Busted!". This odd situation will happen even if the player falls down without being attacked by that cop, such as being bumped or run over by a random NPC's car. It is more than likely to be a glitch. This happens in almost 3D Universe games if not all, but gets patched in the HD Universe for better gaming performance.
