One problem related to fuel injector has been reported for the 2007 Saturn ION. The most recently reported issues are listed below.
My wife was driving our 2007 Saturn Ion to visit family in ky while I am in the middle east(military) we live in va so this is quite a drive. My wife while driving the car noticed the check engine light came on and shortly after the car jerked very hard while traveling at like 60mph, my wife stated that it felt like she was rearended but was not, causing her to swerve some I am glad nothing happened cause my 2 little boys were in the car as well. So my wife took the car to the dealership we bought it from, which is no longer a Saturn dealer but still a gm company. They said we need to replace our fuel pump, and fuel injectors. I did some research on parts and came across the recall on the fuel pump and called the 800 # listed and they called my wife to talk to her and they called the dealership where we bought the car. The dealership we bought the car from stated that the fuel pump while faulted is not faulted due to a defect and that they will not cover the cost and that if we want it fixed it will cost over 1000 dollars. My wife and I feel that this is too much of a coincidence to believe that this is the case. Had something else happened and my wife was to be in a wreck and my family was to be harmed and the diagnoses was that the fuel pump had faulted while driving I would be making sure that my life was devoted to closing this vial company for the good of humanity.
