While driving, I can feel my car "putter", I step on the gas pedal and all the gauges drop down. It takes about 3 times of turning my car back on & pressing the gas pedal before the car will stay on and move. We took it to a mechanic and the engine light was reading a misfire. they changed the spark plugs, and the car is still doing it. they said their only other thought was the coil packs. If other people are having this problem, maybe this should be added to the long list of RECALLS!!!!!!

Started by stalling and idling. Got coil pack and spark plugs changed. Ran great for a couple miles then engine light started blinking and the exhaust sounded loud while accelerating. Misfire in cylinder 4. Brought back and said it needed a new coil pack which I just did. Ran great for a couple miles and misfires again. I'm so upset. I can't afford this.

Parked it for the night, it was fine...woke up the next morning to it misfiring. Put in injector cleaner, chaned boots, plugs, and coil. Also chaned out fuel filter. Next step is ignition coil. Only code coming up is a random misfire code. Still in the process of repairs. I have a 2006 Saturn ion 2 with 71350 miles.

I started my car and it just started shaking then cut off..i started again and it stayed on but shook really bad and engine light was blinking. I drove it a few miles and it would not accelerate. The car kept shaking really bad. So i drove it to the nearest store and stop driving it...someone please help There needs to be a recall on this, if everyone is having this problem

Same problem, many trips to dealer and unsuccessful repair. Went to junkyard and purchased used ignition coils and installed myself and it fixed the problem for a time. Eventually, the problem returned
missing cyl 2 and 4 replaced ign module 2 times and come back with same problem

My oil pan got broken so I had and oil leek and then my engine blew there was alot of smoke and now it keeps making a clicking noise but it won't start!!!
Check engine light is one and is still currently in low power mode. Cylinder 1 and 3 are misfiring but compression is good in both. Replaced coil packs and it didn't help. Replaced fuel injectors, didn't help. Spark plugs are fine. I'm at a loss. Car still does not run.
3rd cylinder misfire, sputters down the road and kicks its horrible. Its in the shop now getting fixed again This is round 2 with the coil

Took car in to have it smogged. When technician hooked it up to test, the engine light came on. He checked it out on the diagnostic and said one cylinder was misfiring and it would cost about $2,000 just to get into the engine not to mention fixing it. What a shame. We had just had both recalls done. We've maintained the car meticulously since we bought it new.
My Saturn had been idling rough. I was at a light and when it turned green she started to jerk forward, then she lost power. It stopped doing this until a little later down the road, she started jerking really bad, she had no power, she stalled in the middle of the roadroad.. THe engine light was flashing like crazy. I tried to start her but she kept dying. Somebody behind me helped push my car to the side. I put her in the shop, told there was asn engine miusfire, but she wasn't reading the code, the mechanic couldn't tell where the misfire was coming from. He knew it was thermal, but the code was not registering on his machine. My brother In law used to be a mechanic, he thought it may be either the ignition coil, modual or my car computer. Since I recently had a tune up with new spark plugs, he changed the wires and cleaned my throttle, otherwise he wanted to put in the ignition coil plus a new modual which would have costmeover $250.00 plus labor. I'm on social security, I didn't have that kind of money. So my brother in lkaw put on a new ignition coil , she seemed to run great after hat for 2 days,then just tonight the engine light came back on, Not sure what it is now, or why it came back on, I'm scasred to drive hger anymore. She used to bye a good car, but I'm getting to where I cant trust her anymore and that's imoortant when owning as car. She has over 96,000 miles on her but she should still run good and last me on down the road. Since a lot of other Saturn owners are having the same issue, there should be a recall to fix these problems. I've already had a recall with her steering issue and key lock, is this another issue???

Car starts then sputters and shuts off when I go to pull out. Misfire noise when it shuts off. When I hit the gas, the rpm's don't even go up. It just dies. It's 5 speed.
