Audio problem: If the player becomes unconscious through the player event of the same name, any dialogue from their character will not stop until it has finished playing.
Other mistake: If the player hits the windows of background buildings or shacks, chips of wood emit from them, despite not being made of wood.
Bug: If the player uses a hit trigger to activate a player event, resetting them to a checkpoint or the driving line while physics resetting is disabled when something hits the ground, the game freezes.
Other mistake: In the Spanish, French and Italian versions of the games, the instructions for the skill games in the example tracks are left in English.
Bug: If the player uses the colour event to colour an object, the object will be displayed with the colour covering the entire object instead of only the parts that can be coloured.
Bug: If the player freezes their bike while travelling at a high speed, they can pass through or be detached from it.
Bug: If the player bails out at a curve while their bailout force is set to a high value and their bike is locked to the driving line, it can go out of the map.
Bug: All windows of residential buildings, and the window from the third variation of the lower wall of the wooden building, have no contact and can be jumped through.
Bug: If the player looks through water, fog will not appear through it. This also happens in Trials Fusion and Trials Rising.
Bug: If the player makes a hole deep enough, it will be rendered as a hill. This also happens in Trials Fusion and Trials Rising.
Bug: If adjustments are made to base world objects, they cannot be undone. The only way to fix the glitch is by restarting the game. In Trials Fusion and Trials Rising, this is partially fixed by switching to another area or restarting the editor.
Bug: If the player has afterburner enabled and is behind water or glass, the trail behind the bike cannot be seen. This also happens in Trials Fusion and Trials Rising.
Bug: If the bike is too far from the rider, it turns invisible. This also happens in Trials Fusion and Trials Rising.
Bug: If the player detaches themselves from their bike through the bike part detach event, they will be off their bike, but the game will assume that they are still on it. This also happens in Trials Fusion and Trials Rising.
Other mistake: In spite of displaying the option of basing the colour value for a seed building from a data source, the player cannot actually perform this action. This also happens in Trials Fusion and Trials Rising.
Bug: If the player attempts to drive while the power for their bike is set to 0%, the bike will drive backward. This also happens in Trials Fusion and Trials Rising.
Bug: If an invisible object has its hitpoints set to zero while the track is running, it turns visible. This also happens in Trials Fusion and Trials Rising.
Bug: If an object's hitpoints are set to zero when resetting to a checkpoint, it turns invisible. This also happens in Trials Fusion and Trials Rising.
Bug: On the Xbox 360 version, if you open the object selection menu and close it without getting any objects, the settings for setting up the track will be displayed despite this already being set up.
Other mistake: In the Xbox One edition of the game, when entering Beggar's Bottom, it is incorrectly referred to as "Fool's Highway."
