I have experienced the failure to shift from the park position into drive on a few occasions. Had to shut the car off, restart and then press the brake pedal down firmly and hold. Shift mechanism operated normally after that event. Not sure if this is a mechanical or electrical issue? I would suspect electrical.
Three weeks ago my 2007 chevy Hhr began not shifting out of park. It takes at least 10 minutes each time I get in my car to shift into drive or reverse. I have tried everything. Now the only way I get it out of park is to turn to key forward and press on the brake and push in the button on the shifter. After about 5 minutes it will finally go into gear. I need to understand what the issue is and if so many people are dealing with the same issue why isn't there any help out there from the manufacturer or a recall to fix this?.
