2003 Saturn Ion won't start in the cold weather

I have a 2003 Saturn Ion and I bought it used a few years ago. A few years ago, only in the Winter it doesn't want to start. then 10 minutes later it will almost start, then 5 minutes later as I wait in a freezing car it will start. Usually after that it is fine for a few days, EXCEPT today. It happened twice today with a Service Engine coming up! I have never noticed it before but what is the Problem with my car? Thank You!!!!!

SOURCE: saturn ion,sometimes wont start

The problem is in the ignition - the grease gets thick in the cold and doent turn quite right the first time. everything turns on, but the anti theft system thinks you have the wrong key so shuts off pwer to the starter. it takes 8-10 mintues to reset. That is why it normally starts when you come back later. I have had the same problem and done tons of reseach. Right now my temp solution has been a small heater and an extention cord. I keep it plugged in over night on a medium setting - just enough to keep the inside temp above freezing. I am also researching remote starts because saturn dealership charges $250 to replace the ignition, and a remote start will run about $300. Saturn wont do a recall because they feel it is not a safety hazard. I say that is bull. Good luck!

SOURCE: Car will not start when cold on first try

its the passlock system. The passlock wire is tiny and fragile, and gets disrupted causing your car to think you are trying to steal it everytime you put your key in.

now you can search for this video on youtube, this is where i learned and ever since i did this i have had NO problem with my car starting for the past 5 months.

you need wire nuts, wire cutters, electrical tape, n socket wrench to take apart steering column

first, go to your fuses, find the airbag fuse and remove it just incase you snip the wrong wire. what you do is look below your steering wheel and take your steering column apart. there are a serious of wires electrical taped together that are plugged in. you peel all the electrical tape back exposing the wires, and you find the WHITE wire. its all white, no other color. This wire is for your Passlock system.... this is the wire that got faulty and is causing the car not to start. now what you do from here is kinda tricky, not too bad though.

Seclude the white wire from the rest, so that you are ready to make your cut. Now, what you do is start your car, leave it running, and while its running you cut the white wire in half. then after cutting the wire, turn your car off, and then turn it back on. it should start right up. Then just put wire nuts on the two ends, and electrical tape them back together

The point of doing this is, one is disables the passlock system completely, and two the reason why you do this while the car is running is because snipping the wire with the car running makes the car think that it got into an accident or something, and puts the BCM/car into a "Fail-safe" mode, making it start every single time no matter what.

i thought this sounded insane at first, but after searching for a couple of hours its the only answer that made sense. and now i am the happiest camper in the world as far as it starting

I too have the same vehicle with the same problem, however I don't think its a battery or alternator problem. I thought those were it at first too however after getting both checked that was not the case. My friends and family who have experience with cars think this is a computer glich of some kind, let me know if you figure this out!
Thanks,

SOURCE: My Saturn ion won't start

sounds like a plugged fuel filter,,,changed it lately?? what might be occurring is,,after turning the engine over for a few minutes,,it just cant get the fuel,,,then after sitting the fuel slowly goes threw the filter,, and you get enough for the engine to start,,,clean filters are a must,,,give this some thought,,,their about 10 bucks if you change it yourself.

My car won't start in the cold weather. I don not have Power Locks or Power Windows. What is the Problem?


That sounds like a battery issue. Batteries have whats called CCA (cold cranking amps) it is the main thing to pay attention to. This is a measure of how much current the battery can provide at 0 deg F. Batteries work better when they are warm, so the colder it gets, the less current it can provide.

Starting an engine requires a lot of current, over a very short time. Meanwhile, cold engines are harder to start, requiring more power to get them going. So look at your battery and its CCA and since u said u bought the car a few years ago. You probably didnt replace the battery yet have u? Batteries usually have a life of 4-6 yrs only. Hope this helped

My 2003 Saturn Ion remote trunk release won't


Check to make sure the button on the trunk latch is turned from manual unlock...they made that feature so only the key will work to open the trunk that way if someone breaks in the front of your car they can't hit the trunk release and get into the trunk...may be the same thing for your remote. Hope that helps.

Hi, i have saturn ion 2003 2.2l the problem is: most of the time it's starts without any problem. But as soon as it starts to get colder, like -5 and colder what apends is this, i will start my car in...


Hi France , I have the same car and had the same problem two years ago : by
changing the ignition switch , this problem will be solved ( cost :around
175$ ) . Its is due to the type of grease used in the original switch which was too thick or inappropriate . Good luck !

Have a 2002 ion that sometimes wont start but if left for 10 mins will start up.


I have 2003 Saturn Ion. I had this problem over and over 2006 - 2008. IT IS THE IGNITION SWITCH. IT IS DEFECTIVE IN ALL ION'S.The replacement may be defective also, not sure. Mine was driving fine, went ino store for 1 hr came out stone cold dead, would not start and key **** in. Had to have towed to Saturn. They said it was battery and replaced battery.I said this did not make sense. 6 yr battery only 3 yr old , never weak start, never run down, in summer? It happened again 2 mo later. They tried to say battery , I said no. They checked battery. It was fine. Could not find problem. They did total electrical check. It happened again 1 mo later. drove into feed store. Went in came out it happened again. I got jump from someone 30 min later and started right up. 2 wks later same, I got jump 20 min later started. 1 mo late same. Sometimes it would just start up. Took to another Saturn place. They said Ignition switch, saturn was having big problem with this on Ions. Got changed and no problems for 1 yr. I was talking to repesentative at Saturn Headquarters. I told the problem. They said the ignition switch has an electrical component, or it is hooked to electrical component. THEY SAID IF I HAD JUST SAT THERE 20 MIN WITH KEY OFF, THE COMPUTER CHIP FOR IT WOULD HAVE RESET ITSELF WHEN IT COOLED DOWN AND I COULD HAVE STARTED IT EACH TIME. IT WAS BEST TO GET REPLACED AND NOT WORRY, BUT THIS WILL HELP YOU IN A STRESSFUL PINCH, UNTIL YOU CAN GET THE IGNITION SWITCH REPLACED. NOTE: Go to Auto Zone , O 'Reilleys, Pep Boys etc, get a repair manuel , CHILTON $ 23- $ 25 , for your year , make, model car. CHILTON IS MUCH BETTER THAN HAYES MANUEL. It is wonderful and many things you can do yourself.

2003 saturn ion will not start somtimes


The security interlock on the ignition switch goes bad. The ignition switch needs replaced. (about $35 from the dealer) It takes about 30 minutes to replace and another 30 minutes to "learn" your key. The car locks out for 10 minutes when it fails so if you look in th emanual there is a procedure to override the lockout but it won't work for 10 minutes. Google the problem there are procedures for the switch replacement and learning the key with the new ignition switch.
