2004 Saturn Ion Problems

What owners report

Owners of the 2004 Saturn Ion most often describe losing power steering assist while driving, usually accompanied by a "PWR STR" message, and a separate pattern of no-start conditions that many attribute to the Passlock anti-theft system. Complaints describe both as intermittent and often resolved temporarily by shutting the car off and restarting it, and many report the steering issue well past 80,000 miles. Other recurring themes include fuel odors and leaks near the fuel filter and lines, airbags that did not deploy in collisions, and hard or delayed shifts.

1. 1
   Steering

   Power steering assist cuts out while driving

   • 355 complaints (40%)
   • median 87,000 mi at 6.9 yrs old (312 state mileage)
   • 24 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 35 quotes)
   • filed 2004–2025

   Owners describe the steering suddenly becoming very heavy, often with a warning chime and a "PWR STR" message, then returning to normal after the engine is shut off and restarted. Some say it happens repeatedly in a single trip, others only occasionally, and some notice it more in hot weather. Complaints mention dealers being unable to reproduce the fault, quoting replacement of the steering column or power steering motor, or telling owners no recall applied to their vehicle. Mostly reported between roughly 50,000 and 180,000 miles, with several owners noting the first occurrence past 100,000 miles.

   Recall 14V153000

   What to check: Drive the car long enough to see whether the steering warning appears, and ask whether the electric power steering recall work was ever completed. Note that the recall covers a sudden loss of assist, not every steering complaint.

   “Shortly after buying this vehicle, I have had numerous failures of the power assist steering system. At any speed, at any time, pwr str dis displayed on the obd display, simultaneously as the motor stopped functioning, forcing me to unexpectedly manually steer the car until the ignition was cycled and the system reset. Sometimes this happens 1-7 times a day. I have personally came close to having a single car accident due to power assist failure while curving. …”

   NHTSA complaint #10459801, filed 2012-05, 138,000 miles

   “I have a 2004 Saturn ION (red line). In july of last year, my power steering went out while driving. You have to turn the car off and restart it in order to reset the power steering. The problem occurred twice that month and did not happen again until june of this year. It has happened 5 times since. I have noticed that the problem usually occurs when the weather is hot (over 90 degrees). Other than that, there is no set circumstance. It can just go out at any time. …”

   Electrical system

   No-start in cold weather (Passlock / ignition)

   • 357 complaints (40%)
   • median 57,816 mi at 5.4 yrs old (270 state mileage)
   • 14 mention a crash, fire or injury
   • owner-quoted repair $665 (median of 28 quotes)
   • filed 2004–2025

   Complaints describe the engine failing to crank or starting and immediately dying, most often in cold weather, with normal operation returning after waiting about 10 to 30 minutes. Owners frequently link it to the Passlock anti-theft system or the ignition switch, and report dealers re-coding keys and switches or replacing batteries and starters without resolving it. Some also describe the key sticking in the ignition or the dash lights staying on after the key is removed. Reported from very low mileage up past 120,000 miles, most often in cold weather or after short stops.

   Recall 14V171000Recall 14V047000

   What to check: Ask whether the ignition switch recall (14V171000) was performed and whether the key can be removed with the engine still running. On a cold morning, check that the car cranks promptly and that the security light behaves normally.

   “My 2004 Saturn ION does not start in cold weather. It has a brand new battery and starter, yet it is still having this problem. It will generally start after waiting about 15 minutes to try again. The consequences are being delayed 15-20 minutes each time I want/need to go somewhere.”

   NHTSA complaint #10263525, filed 2009-03, 66,000 miles

   “My Saturn ION 3, 2004 will not start when it is cold. You have to wait 10 minutes and then try again to try to get the car to start. The car eventually starts. I called Saturn to inquire about this and they said that it is an ignition switch problem with their passlock system. They fix about 10 of them every week, b ut Saturn has yet to recall the switch. This problem happens almost everyday in the cold and has been happening to my car for over a year now.”

   Transmission and drivetrain

   Harsh or delayed shifting and loss of power

   • 124 complaints (14%)
   • median 72,000 mi at 7.5 yrs old (105 state mileage)
   • 5 mention a crash, fire or injury
   • owner-quoted repair $588 (median of 10 quotes)
   • filed 2004–2020

   Owners describe the car hesitating or losing power on acceleration, sometimes taking many seconds to move from a stop, and hard shifts between first and second gear. One complaint describes repeated dealer visits where the computer reported no fault before a transmission replacement was approved; others mention clutch and shifter hardware problems on manual cars. Reported from a few thousand miles up to around 65,000 miles, including both automatic and manual cars.

   2 related service bulletins

   What to check: Test from a stop and through the first few shifts, watching for hesitation, slipping or delayed engagement, and ask whether the transmission fluid has been serviced. For manual cars, check the shifter and clutch pedal feel.

   “I first took my 2004 Saturn 3 ION quad coupe to the dealer with a transmission problem. As I would accelerate the car would lose speed. I never knew when this was going to happen. It happens at any speed. At the time of my first complaint there was 27,539. I now have 33,020 and finally after 3 months and 12 trips to the dealer they are putting in a new transmission. Every trip to the dealer resulted in my being told that the computer said nothing was wrong with my car. …”

   NHTSA complaint #10135992, filed 2005-09, 27,539 miles

   “My car hesitates when shifting from first to second gear. Once the clutch is out and you apply the throttle the car goes then looses power and then goes again. This car was is in the shop the last 26 of 39 days for 4 seperate attempts to fix it. The dealer states they can not fix it and that Saturn corporate has no idea what is wrong with it either. No one from Saturn customer care has once asked me for my side of the story or the 6 pages of documentation on how I was treated and told would be done to repair my car. …”

   Fuel system

   Fuel odor and leaks at the fuel filter and lines

   • 39 complaints (4%)
   • median 100,500 mi at 11.6 yrs old (32 state mileage)
   • filed 2008–2022

   Owners describe a strong gasoline smell around the car, a visible leak near the rear driver side while the engine runs, and difficulty removing a corroded fuel filter from the line. Some say a shop found a leaking fuel line during routine service. Several complaints note that a fuel-system recall existed but their vehicle identification number was not included. Generally reported past 85,000 miles, often above 100,000.

   Recall 04V281000Recall 04V003000

   What to check: Smell around the rear of the car with the engine running and look for wetness at the filter and lines. Ask whether the fuel system recalls were completed and whether the filter has been changed recently.

   “Tried taking fuel filter off last july took a whole weekend of using penatrating oil and freeze off then I finally got the tabs to come loose, I thought maybe I messed up the new filter or didnt get enough rust off the fuel line and that's what was causing the strong smell of gas nd poor performance but changed it again and still that same problem but now theres a leak. …”

   NHTSA complaint #11398818, filed 2021-03, 100,000 miles

   “Fuel leak on rear driver side when the engine is running while car is stationary. It may have happened before the date and mileage stated below but that's when I first noticed the fuel leak.”

   Air bags

   Airbags not deploying in collisions

   • 52 complaints (6%)
   • median 55,000 mi at 4.7 yrs old (25 state mileage)
   • 30 mention a crash, fire or injury
   • filed 2004–2023

   Complaints describe front and side airbags failing to deploy in impacts, including rear-end, head-on and animal strikes, sometimes with an airbag light afterward. In one case the seat also collapsed rearward on impact. Owners report these as collisions rather than as an intermittent warning, so there is little information on what diagnosis or repair was attempted. Reported from under 10,000 miles to well over 200,000 miles, across a wide range of conditions.

   Recall 14V047000

   What to check: Check that the airbag warning light comes on with the key and then goes out, and confirm with a scan tool whether any airbag faults are stored. Ask whether the airbag-related recall was completed.

   “I was driving at night on a country road when a deer ran out in front of me and the car struck it. The car sustained some front end damage and the cabin filled with smoke. The seat-belts locked up but the airbags never deployed. Now the airbag light is on and the seat-belts are locked up. It concerns me that with everything that happened that the airbag should have when off.”

   NHTSA complaint #10502620, filed 2013-03, 239,512 miles

   “Driving 60 MPH on the expressway, I was run off the road by a semi truck on the right side of the road. I hit a highway sign head-on. The airbag did not deploy, although the damage to the car was extensive. Thankfully I had my seat belt on, but sustained bruises.”

   NHTSA complaint #10572631, filed 2014-03, 60,000 miles

Buying note. This is an old car, so condition and service history matter more than the model year; verify that the ignition and power steering recalls were completed and that no steering warning appears on a test drive. A pre-purchase inspection focused on the steering assist, fuel lines and battery/starting system is worthwhile given how often those are described in complaints.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
