2003 Saturn Ion Problems

What owners report

Owners of this model year most often describe electrical problems, especially a no-crank or delayed-start condition that tends to appear in cold weather and sometimes clears after waiting ten to thirty minutes. Power steering assist cutting out is the other frequently reported theme, usually described as intermittent and sometimes tied to hot weather or low-speed turning. Many complaints come in between roughly 30,000 and 130,000 miles.

1. 1
   Electrical system

   Cold-weather no-start / delayed start

   • 240 complaints (32%)
   • median 63,000 mi at 6.1 yrs old (161 state mileage)
   • 3 mention a crash, fire or injury
   • owner-quoted repair $425 (median of 10 quotes)
   • filed 2003–2024

   Owners describe turning the key and getting only a click, no crank, or an engine that starts and immediately stalls, often on cold mornings. After waiting anywhere from a few minutes to half an hour, the vehicle typically starts normally. Several complaints say the battery, alternator, and starter were checked or replaced without resolving it, and some mention the dealer replaced the ignition switch or pointed to the body control module and Passlock sensor. Mostly reported between roughly 20,000 and 130,000 miles, with many owners tying it to cold weather or temperature swings.

   Recall 14V047000

   What to check: Ask whether the ignition switch campaign work was done and whether the ignition switch or Passlock components have been replaced. On a cold start, listen for whether the engine cranks immediately or only clicks.

   2 excerpts from owner complaints in NHTSA records

   “I have a Saturn ION 2003 and spent the whole of last winter having to go out and turn my key in the ignition 10 minutes before I needed to leave anywhere so it would start. It actually started in 2006 and the car did not start a couple of times during the winter. Georgia had a mild winter that year. Unfortunately, 2007 was much colder and my car constantly would not start. …”

   NHTSA complaint #10228708, filed 2008-05, 75,000 miles

   “My 2003 Saturn ION refuses to start when it is cold but after 10 mins it will decide it wants to start. I have been stranded and put hundreds of dollars into this problem with the mechanic not seeing the problem. Put a new ignition switch in the car and still has the problem. After doing some research on the web many Saturn owners are having the same problems. This needs to be a recall and Saturn is refusing to do so.”

   Steering

   Power steering assist cuts out

   • 152 complaints (20%)
   • median 96,000 mi at 9.9 yrs old (130 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $700 (median of 13 quotes)
   • filed 2003–2026

   Owners describe the steering suddenly becoming very heavy, often with a power steering warning message, sometimes while turning at low speed or after the vehicle has been running in hot weather. Restarting the car often restores assist temporarily, and complaints mention the power steering motor being identified as the cause. Some owners were told their vehicle was not covered by the related steering recall. Reported from around 23,000 miles up past 170,000, with several owners noting it during hot weather or repeated low-speed steering.

   What to check: Test the steering at low speed in a parking lot and watch for a power steering warning message. Ask whether the power steering motor or column has been replaced and check the VIN against the steering recall.

   “I have been driving a 2003 Saturn ION for a few months now. I started here a popping noise in my steering wheel a few weeks back and when I took it to get looked at I was told it is most likely the power steering motor. After doing some research it was found that there was a huge recall by general motors for this part, but my car was not part of the recall.”

   NHTSA complaint #10324150, filed 2010-04, 61,000 miles

   “My power steering kept cutting out. (been doing this for about 2 years now) while I was driving today the worst situation happened. I went to turn at an intersection and mid turn the power steering message appeared and my steering wheel tightened and straightened back out a little bit. I was trying to get into the turn lane but to avoid an accident I sped up to merge with the farthest lane and unfortunately I popped a tire and bent the rim. This needs to be addressed before someone gets killed. …”

   Electrical system

   Key sticks or won't release from ignition

   • 250 complaints (33%)
   • median 70,000 mi at 6.7 yrs old (183 state mileage)
   • 9 mention a crash, fire or injury
   • owner-quoted repair $481 (median of 16 quotes)
   • filed 2003–2026

   Complaints describe the key binding or seizing in the ignition, sometimes requiring wiggling or a locksmith to remove it, and in a few cases the engine continued running after the key was pulled. Owners report the ignition lock cylinder, housing, and keys being replaced, and some say the problem returned after the recall repair was performed. Reported across a wide mileage range, from about 60,000 miles up past 180,000, in everyday parking and shutdown situations.

   Recall 14V171000Recall 14V047000

   What to check: Park the car, shift into park, shut it off, and confirm the key turns freely and comes out every time. Ask whether the ignition recall was completed and whether the lock cylinder has been replaced since.

   “My key switch doesn't allow me to remove my key when I'm in parked and my transmission strands at times and my car doesn't start all the time when I try to start it I have to sit and wait awhile before it starts again I could be sitting in the drive thru on parked waiting to travel again on th he main roadway”

   NHTSA complaint #11342756, filed 2020-08, 139,000 miles

   “While there have, been no adverse deaths or injuries there is a problem that has happened multiple times that could lead to deaths. I have a 2003 Saturn ION and have had to replace the ignition 2 times. The ignition locks up and the car will continue running even if I remove the key.”

   Air bags

   Airbags not deploying in a crash

   Mentioned in 4 of 60 sampled complaints

   Some complaints describe collisions in which the airbags did not deploy, and others note that the airbag-related recall repair had not been completed because parts were unavailable at the time. A few owners link the non-deployment to electrical faults elsewhere in the car. Reported mostly in the 60,000 to 180,000 mile range, in the context of crash events or recall follow-up.

   Recall 14V047000

   What to check: Ask the dealer to confirm by VIN whether the airbag-related recall was completed, since parts availability delayed some repairs. Check that no airbag warning light stays on after startup.

   Transmission and drivetrain

   Transmission hesitation and hard shifting

   • 78 complaints (10%)
   • median 72,542 mi at 7.8 yrs old (62 state mileage)
   • owner-quoted repair $1,150 (median of 9 quotes)
   • filed 2003–2024

   Owners describe hesitation when pulling away from a stop, abnormal deceleration while accelerating, and shifting problems that shops sometimes could not reproduce. Some complaints report the transmission needing replacement after a diagnostic, and others mention a front-end vibration along with the shifting concern. Reported from about 5,000 miles up to roughly 140,000, often in stop-and-go or acceleration situations.

   1 related service bulletin

   What to check: Drive from a stop and through several upshifts, watching for hesitation or slipping. Ask whether the transmission fluid was serviced and whether any transmission repairs or replacement have been done.

   “I have a 2003 Saturn ION that is having shifting problems. The car has 52,000 miles on it, and it is out of warranty, my daughter originally had the car, and drove it, without me knowing she was having problems with it shifting. Also there seems to be a vibration in the front end. I am taking it in for evaluation. I have had it in several times for the transmission, but they couldn't find anything wrong. I don't understand GM not doing something about these transmission problems. Also the seat belt locks and you can't get out of it. …”

   NHTSA complaint #10150986, filed 2006-02, 37,000 miles

   “The contact owns a 2003 Saturn ION. While accelerating onto a highway at 40 MPH, the vehicle began to abnormally decelerate without warning. The vehicle was towed to a local repair facility where a diagnostic test indicated the transmission would need to be replaced. The manufacturer advised they would get back with the contact to determine if any assistance would be provided. The vehicle was not repaired. The failure and current mileages were 74,085.”

   NHTSA complaint #10340407, filed 2010-06, 74,085 miles

Buying note. Check that the ignition and airbag recalls were completed for the specific VIN and test cold starting and low-speed steering before buying. A pre-purchase inspection focused on the ignition switch, power steering, and transmission is worthwhile on this model year.
