Aguero has scored eight goals in as many league games for Pep Guardiola's team this season and is the joint top-scorer alongside Chelsea forward Tammy Abraham.
City, though, have been weak in defence and have lost twice already this term.
The Argentine, 31, was unhurt despite the front wheel and side of his grey Range Rover being mangled.
Aguero will hope to lead Man City to victory when the host Aston Villa on Saturday in the Premier League.
Aguero accompanied the image with a caption reading: "What a great morning".
The Argentinian striker's image shows the driver's side front wheel nearly horizontal, while the wheel arch and front bumper sustained significant damage.
Aguero will now turn his attention to being fit for this weekend's clash with Crystal Palace.
Two years ago, the Man City star cheated death - left only with broken ribs - after the taxi he was travelling in ploughed into a lamppost in Amsterdam.
"Sergio Aguero is not here because he's been carrying a problem and has not been training 100% with his club", national manager Lionel Scaloni was quoted as saying at a pre-match press conference.
