Questionable, suspicious, or unreliable; seeming dishonest or likely to fail; risky or uncertain.
From the verb 'dodge' (to avoid or evade), with the suffix '-y' to make an adjective. Someone or something 'dodgy' seems like it's trying to dodge accountability or truth.
In British English, 'dodgy' is one of the most common words for describing something suspicious or unreliable, but the word doesn't appear in American English nearly as much—it's a great example of how different English-speaking countries develop different slang!
