My wife's g20 is an automatic. It's having issues shifting from "park" to "Drive" or anything else. When we start the car, press on the brake pedal and try to shift out of Park we cannot depress the safety button on the shifter. Sometimes it works correctly (one attempt) while sometimes the button won't push in until the 20th or more time. I believe the problem to be in the shifter. Something worn out that needs replacing? Anybody have experience with this?
