The first time the ignition switch "passlock" sensor went out on my 2003 Saturn Ion II, it was near zero degrees outside, my 2 month old son was along, and I was stuck on the road for several minutes trying to restart the vehicle. The problem is apparently that a sensor that controls the gas flow stopped working properly and the car died. I was able to pull to the side of the road. When trying to restart the vehicle, it initially did nothing. I waited several minutes, called for my son to be picked up, then tried again. After about 15 minutes it started without a problem. I learned that the ignition switch was faulty and had a faulty "passlock" sensor. Apparently, when the ignition is too cold, the grease begins to harden, causing the switch to be unable to make proper contact. This makes the car think someone is trying to steal it, so the security system kicks in and stops gas flow for up to 15 minutes. After that period of time, the security system resets and you can once again attempt to start the vehicle. However, if the grease has not warmed up enough by the, the whole thing starts over again. I had the switch replaced and everything was fine until today. The switch is again going bad. My husband had to be to court this afternoon and was unable to start the car. This time we had to wait and try again 3 times, wasting 45 minutes. At least this time it was only time that was wasted. Last time it could have been a major safety issue. My baby could've been exposed to the cold for too long with serious consequences. Not only that, but I could have been hit by other cars if I hadn't been able to move it out of the way. Now that it has happened a second time to our vehicle, I did some research online and have seen that this problem happens quite regularly and that Saturn has refused to do anything about it.

2003 Saturn Ion will not start when it is cold. I am seeing alot of people posting on different forums with the same issue. Is anything going to be done about this?

I own a Saturn Ion II 2003 and every morning that it is cold it will not start. After getting a new battery, which is what the dealership advised me to do, it still will not start on cold mornings. There are several complaints out there about this issue in 03 to late 04 models regarding the replacement switch not turning in cold weather. These vehicles need to be recalled.

I have a 2003 Saturn Ion-3 and it will not start below 40 degrees, this is a ridiculous problem. There is a thread about this problem at : www.autosite.com/content/research/forums/index.cfm/action/posts/fid/5610 there are many people with this problem and so far nothing has been done, I am just hoping I can sell this car asap because it has been quite a problem.

The vehicle would intermittently not start. This mostly occurred in below freezing temperature conditions but would also occur in above 70 degree temperatures. The vehicle also stalled while being driven and could immediately be restarted. The vehicle was taken to the dealer who replaced the ignition switch.

- Sullivan, MO, USA

: the contact stated the vehicle would not start right away in cooler weather, for at least 15 minutes. Through internet research, the contact believed the problem was the ignition switch. An appointment had been scheduled with a service dealer and the manufacturer was notified.

- Stillwater, MN, USA

: the contact stated while driving on the freeway between 50-60 mph, the vehicle lost all electrical power. There is no warning when this occurs and the steering wheel also locks up. The vehicle is pulled over and restarted. The dealership replaced the ignition switch and fuel pump. The contact has been out of the country since the repair, last year; the vehicle has not been driven since repairs were made.

Over the past 2 and 1/2 weeks we have had a problem starting our 2003 Saturn Ion. The car would not start leading one to believe there was a problem with the battery. Then a few hours later the car started and the service engine light came and went very quickly. A week later, the same thing happened and the car started up again later with no problem. A few days later the same thing happened. The local Saturn service tech advised us that this problem has been seen with other Ions and that the ignition switch would have to be replaced.
