The long-time sponsor of the football governing body voiced concerns about the "conflicting perspectives" surrounding the report, which last week cleared Russia and Qatar of corruption in their controversial winning bids.
Fifa has since said it will further review the bidding process.
In a statement reported on ITV News, a Coca-Cola spokesperson commented: "Anything that detracts from the mission and ideals of the Fifa World Cup is a concern to us.
The current conflicting perspectives regarding the investigation are disappointing. Our expectation is that this will be resolved quickly in a transparent and efficient manner."
Ethics investigator Michael Garcia criticised the conclusions reached by German judge Hans-Joachim Eckert, and called it it "incomplete and erroneous".
