In owners' own words
I have a 2004 Saturn ion. About 3 weeks ago I had the transmission fluid flushed and changed. Then on january 13, 2010, my car stalled on me.
2004 Saturn ION vti transmission failure, pulling out of a fast food drive thru at a slow rate of speed, hundreds of miles from home.
It is becoming apparent that the clutch master cylinder on the 2.2L and 2.4L Saturn ION is defective. There have been many complaints about this on multiple forums across the internet.

Recalls for the 2004 Saturn ION: 10
The weight on the key ring and/or road conditions or some other jarring event may cause the affected ignition switches to move out of the run position, turning off the engine and disabling the air bags. If the ignition switch moves from the run position to accessory, the car would stall and the air bags will not deploy in the event of a crash, increasing the risk of personal injury to the occupants.
In the affected vehicles, the key can be removed from the ignition when the ignition is not in the "Off" position. If the key can be removed from the ignition when the ignition is not in the "off" position, the vehicle could roll away: (a) for an automatic transmission, if the transmission is not in the "Park" position…
In the affected vehicles, there may be a sudden loss of electric power steering (EPS) assist that could occur at any time while driving. If power steering assist is lost, greater driver effort would be required to steer the vehicle at low speeds, increasing the risk of a crash.
This defect can affect the safe operation of the airbag system. The key fob (if applicable), should also be removed from the key ring. In these models, the weight on the key ring and/or road conditions or some other jarring event may cause the ignition switch to move out of the run position, turning off the engine. If the key is not in the run position, the air bags may not deploy if the vehicle is involved in a crash, increasing the risk of injury.
These headlamps fail to conform to the requirements of federal motor vehicle safety standard no. 108, "Lamps, reflective devices, and associated equipment." These lamps do not contain the required amber side reflectors. Decreased lighting visibility may result in a vehicle crash.
Certain passenger vehicles have a condition in which the turn signal lamp and daytime running lamp (Drl) on either front side can stop working because of loss of contact between the bulb and socket. If a front turn signal lamp is inoperative, others may react more slowly to a turning vehicle and a crash could occur.
Certain vehicles equipped with supercharged 2.0L 4-CYLINDER (Lsj) engine were built with a fuel feed pipe that could crack and leak fuel near the fuel rail. If fuel leaks from the fuel feed pipe, there would be a noticeable fuel odor around the vehicle. Fuel leakage, in the presence of an ignition source, could result in a fire.
On certain passenger vehicles, some welds between the passenger's side motor rail and the front bumper bracket do not meet engineering specifications. Long term durability of the joint may be reduced and separation of the bumper from the frame on the passenger's side of the vehicle may result, increasing the risk of a crash.
Certain passenger vehicles fail to comply with the requirements of federal motor vehicle safety standard no. 118, "Power-operated window, partition, and roof panel systems." The power windows and/or sunroof may be operable after the ignition has been turned to the "Off" Position and the front passenger door is opened. If unsupervised children are left unattended in the vehicle and operate the power windows or sunroof, there is an increased risk of injury to the child.
Certain passenger vehicles equipped with 2.2L 4-CYLINDER (L61) engines were built with a fuel filter that could corrode prematurely on the exterior surface. If corrosion on the exterior surface of the fuel filter progresses to the point of creating a hole in the shell, fuel droplets could form and drop to the ground. If an ignition source is present, a fire could result.
