2003 Saturn Ion (Page 6 of 11)

CarComplaints.com Seal Of This Might Hurt

CarComplaints.com Notes: The Saturn Ion was a compact bundle of hurt wrapped up in a cheap, plastic shell. With so many defective components and a safety rating that a bicycle would be ashamed of, it’s a blessing this car only lasted five model years.

The 2003 (and 2004) Ion was cursed with GM’s flawed attempt at a continuously variable transmission, known as the VTi. It had such a high failure rate that a class-action lawsuit was filed against GM, eventually prompting a settlement and a warranty extension. GM discontinued the VTi for the 2005 model year – surprise, surprise.

The 2003 Ion was also part of one of the largest and most controversial recalls of all-time. A defective ignition switch in millions of GM vehicles could accidentally turn the car off and disable important safety components like the power steering and airbags. The problem resulted in at least 13 deaths, but what made it worse was that GM knew about the issue for 10 years before doing anything about it.

So was the transmission warranty extended? Yeah. Was the ignition switch recalled? Eventually. Is this car safe to drive? Not really. Honestly, you’re better off looking elsewhere.

Ion 4-cyl

  • 64,110 miles
Randomly, my 2003 Saturn Ion-3 refuses to start due to the widely known yet unresolved ignition switch passlock problem. The occurrences have steadily increased in frequency over the last couple of years. The potential safety consequences of this prevalent issue are being overlooked, and it should be formally investigated. Additionally, it raises concerns about faultiness in other critical components. The repair costs are unfair to us consumers for this admittedly faulty part; it should be handled by recall.

Ion 4-cyl

  • 106,750 miles
The issue is in connection with a 2003 Saturn Ion. Recently, while driving, there appears to be a click coming from the front left side of the car, most likely coming from the fuse box. Immediately following the click, there is three dings followed by a message on the dash "pwr str". after this has occurred, the vehicle loses its power steering abilities, causing significant more force to be used when operating the vehicle. Typically this is fine when on a straight road but often this is not the case as I drive on roads with sharp curves leading to the risk of significant danger if I was to lose power steering while taking one of these turns. If the car is turned off while in motion and then turned on again the power steering does begin to work again although often the events occur again and the car loses power steering.

Ion 4-cyl

  • 25,000 miles
2003 Saturn Ion-3 purchased new began not starting in 2009. After waiting approximately 10-15 minutes the car starts up. Took the car to a repair shop where a diagnostic test was done and they could not find a problem and could not reproduce the car not starting. Went on-line and discovered numerous complaints from other Saturn Ion owners regarding this exact problem. Wrote a letter and sent copies of these same complaints to GM in January 2009. A service rep. Called me saying they had no recalls for this problem and nothing could be done about it by GM. Starting having many more incidents of the car not starting in 2010, but waiting the 10-15 minutes and the car then starting. Sent an E-mail to GM regarding this issue. Again a service rep. Called and said due to the age of the car I should take it to an authorized dealer and the repair, if they could find it, was my responsibility. This issue can be quite serious since you cannot start your vehicle and are left sitting there in conditions that could be dangerous (very cold weather, late at night, etc.) lately this situation has happened 6-8 times in two weeks. It would certainly help if GM knows about this situation and would issue a recall.

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"?"

Vehicle was taken to authorized Saturn dealer, 2003 Saturn Ion had continuous high engine idle after being driven at highway speeds. If vehicle was shut off the power control module(PCM) computer reset it self. Saturn dealer serviced the vehicle by re-programming the PCM( 10/21/10) as per a issued service bulletin of 4/2004. This did not work. Then they advised a spring in throttle body (engine) was bad and replaced spring ( 10/28/10). This also did not work, engine still has high idle and I bought the vehicle back on 11/2/10 to the service dealer.. service dealer then hooked up car to computer and has ser tech drive vehicle for over 25 miles, 2 times ; and thenfound another problem. They indicated that the power control module computer had a short and caused a burned out component in the computer. Since the Saturn is no longer being produces, the computer which must be replaced is on back order; and unknown when part will arrive. The Saturn service dealer ( ingersoll auto in danbury ct) advised that the vehicle should not be driven as it was a safety hazard, since the computer controls not only the engine but the ABS braking system. At this time unknown when a part will arrive as it is on back order. In searching the internet I found numerous complaints from person who also had problems with the power control module computer. I believe that GM/Saturn has had full knowledge of the problem and should have taken care of this problem prior; and as other owners of Saturn are having this serious problem then GM should be making replacement parts for this computer more available to Saturn owners. Ingersoll auto in danbury ct has advised me that they do notknow when the replacement computer will be available as there is no part available in the entire usa. Part will have to be made by GM and unknown when this will happen. So my 2003 Saturn Ion must be left at the dealer until a replacement computer is sent by GM, so my car can be repaired.

2003 Saturn Ion, this is the second ignition switch to be replaced in this car. On this occasion the key will not release from the switch. This appears to be a major problem with Saturn..why no recall?
