Front Air Bag Sensor Control problems of the 2006 Saturn ION

2006 Saturn Ion-3 automatic 2. 4l 1. Power steering: power steering goes out nearly every time I drive the vehicle. Saturn dealership changed a sensor I the steering column, but problem persists. It is very dangerous to be driving in the city without power steering. 2. Ignition: car refuses to start when temperature is below 15-20 degrees fahrenheit. I have been stranded in below freezing weather for almost an hour because of this common Saturn failure.

Key cannot be removed from ignition after car is turned off. Have returned to the dealership 4 times for this problem. Each time they lubricate the system but it does not fix the problem. It began less than 6 months after we purchased the vehicle and still persists today. We cannot take any more time off from work to take it into the shop to be told they will not replace the ignition system or the transmission/gear shift mechanism that may be the actual problem. In addition, in the first 18 months we've owned the vehicle, the air conditioning coolant has run out and they cannot locate the leak, and the sunroof broke. Finally, on one occasion the car went over a bump at approximately 30 mph and the electrical system acted as though the car had a wreck, cutting the motor and showing the airbag had deployed when it had not. After a few minutes, the car started up just fine with no adverse affects. The dealer says they've never heard of such a thing and can't think of how/why it happened.
