Like everything, none of the Carmageddon games are perfect, so glitches (also known as bugs) are more than likely to occur. Some may be harmless, while others can make a race incompletable.
This page lists all (or most) known bugs.
Name: Most glitches don't have a name, so the name given just helps to identify them.
Reproducibility: How often can this glitch be reproduced. Low, Medium or High.
Cause: Why this happens.
Code: Caused by some coding flaws, such as allowing a variable to reach unwanted values.
Engine: Caused by a problem with an engine: physics, sound, graphic, etc.
Design: Caused by faulty location, model, etc. design.
Harmless: No if the glitch can make the game unplayable or have other serious effects. Yes otherwise.
The Suppressor's gear counter is graphically incorrect, showing bits of the surrounding numbers above and below the current one, and gears 7 and 8 are just garbage graphics.
If the player wins a race with a lot of spins in mid-air, they'll be granted a Cunning Stunt bonus when the next race starts, provided they haven't landed after winning, and that the game hasn't been exited in the meantime. Video
