The Argentine striker has now netted eight goals in his four Serie A appearances to date this season and his latest treble was particularly satisfactory as it came in his 100th appearance for the Old Lady.
Paulo Dybala's hat-trick gave Massimiliano Allegri's side the victory at MAPEI Stadium and maintained their 100 per cent start to their title defence.
Sassuolo managed to get a consolation goal through Matteo Politano after a Stephan Lichtsteiner error on 51 minutes.
He has scored back-to-back hat-tricks away from home in Serie A (against Genoa and Sassuolo).
Dybala has often been likened to Messi and has even been linked with a move to Barcelona to join up with his compatriot with a view to becoming his long-term successor as the Catalans' number 10. "The team gives me confidence and I also compliment the coach, who gives me the freedom to play where I want".
Juve's win takes them above Inter to the top of the table.
Roma eased past Verona 3-0 on Saturday.
