My ignition was recalled but the mechanics at gm crestview didn't know how to reset the computer so all my lights stayed on for check engine. Now my ignition is acting up and my car won't turn on. Is it still covered under the recall?

Takata recall the seat belts when stopping suddenly do not always lock up. This is very dangerous especially with kids. The fuel system has been producing a check engine light at certain times of fueling up. And the fuel pump will knock occasionally even after it's been changed. The suspension is really bad and dangerous, rattling noise and shaking.

Filed Apr 22, 2014 · Acceleration, Steering · 78,000 miles · CA

I was driving along the highway when my car began to accelerate and shift gears strangely. The check engine light came on and then a warning about the power steering. It did feel a little bit harder to drive. Took it to a mechanic who said something about the transmission had come up instead of power steering. Took it to another place who said it was a computer control module. Once checked, engine light turned off and car drove normally. Happened again in march, lost power steering for a few miles before it came back. Engine light came on, stayed on for a day, and then turned off. Searched online for other instances of this happening and found other saturn ion owners complaining of same thing, only it applied to 2004 and later. My 2003 is having the same issue as their's.

2003 ion saturn will not start on cold mornings. This started 2010 in january. I have taken to firestone to fix. Wasn't cold enough. Car started. Now weather is colder and car will not start. Service engine light comes on. Then nothing. I have noticed several complaints of this same type that I am having. My car only has 60,000 miles. New battery put in jan 2010. Car mechanic said cannot determine problem until car won't start for them. Very frustrating. This is really the only problem I have had with my 2003 saturn ion. Wanted to keep car for a long time. After the weather gets warmer during the day, car will start right up. Recall???

The biggest issue is that on cold days (and sometimes not so cold) my car will just click and not start, or will start and die out. But if I keep trying to start it and let it sit for awhile and come back, it will start right up. When it does this, they check engine light usually comes on when trying to start it, but when I get it started it immediately goes off. I've had the battery, alternator and starter checked and they are fine. It only happens usually in the mornings or late at night when it's been cold.
