One problem related to tank assembly has been reported for the 2007 Porsche 911 Turbo. The most recently reported issues are listed below.
The problem with my 2007 Porsche turbo is that when I go to fill up gas the tank will not fill pass 2/3 of the tank. The problem happens most of the times that I fill up gas and Porsche has told me that there is no fix to the problem. I am sure that it is not only my car that has this problem as I have searched on the internet and have found others with similar issues. Out of the many times I have taken the vehicle in for service one time they change the gas tank and relating parts but it did not fix the issue.
