2004 Kia Spectra Problems

What owners report

Owners of the 2004 Kia Spectra most often write about automatic-transmission shifting problems and air-bag warning lights or bags that did not deploy in crashes, with both themes showing up across the whole mileage range from a few hundred to over 100,000 miles. A smaller group describes engines that rev or accelerate on their own, occasionally when a brake pedal is pressed, and dealers in many of these reports were unable to reproduce the condition.

1. 1
   Air bags

   Air-bag warning light on and bags not deploying

   • 25 complaints (35%)
   • median 35,000 mi at 3.4 yrs old (17 state mileage)
   • 12 mention a crash, fire or injury
   • filed 2004–2017

   Many complaints describe the air-bag warning light staying on or coming on intermittently, including after the air-bag recall repair was performed, and some owners say the passenger seat sensor did not recognize an occupant. Others report frontal or side impacts in which no air bag deployed, and a few link the light to a control module mounted under the center console cupholders where spilled liquid or condensation reached it. Dealers in several reports replaced seat parts, buckles or the module without clearing the light, and in some cases said they could not find a fault. Spread across the whole mileage range, from near-new vehicles to over 140,000 miles.

   What to check: Turn the ignition on and confirm the air-bag light goes out after the self-check, and ask whether the air-bag recall work was done. Keep liquids away from the cupholders above the console-mounted module, and have any persistent light diagnosed before buying.

   “2004 Kia Spectra on 3/20/06 was impacted on passenger side within the area of front and rear doors. The impact forced the rear of my car to slid away from impact and come in contact with a pickup truck damaging my drivers side rear quarter and not one air bag in my car deployed and there are 8 air bags in this model car.”

   NHTSA complaint #10154363, filed 2006-04, 31,000 miles

   “I had no indication that my seat belt or airbag were faulty. While driving at 40 MPH I struck a car that turned left directly in front of me. My seat belt failed to lock and I was lifted out of the seat and hit my head, shoulder, and hip on the left side of my car. The airbag did not inflate. The insurance adjuster could not believe that the airbag didn't inflate considering the force of the impact.”

   Transmission and drivetrain

   Automatic transmission won't shift or slips

   • 19 complaints (27%)
   • median 17,000 mi at 1.5 yrs old (17 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2004–2014

   Owners describe the automatic transmission failing to move into a higher gear from a stop, revving without engaging, or slipping and then jerking into gear, often forcing the driver to shift into neutral and back to drive to get moving. Several report repeated dealer visits where the problem could not be reproduced, and some say they were told the behavior was normal or that the computer was not sending correct shift signals. A few reports mention multiple transmission replacements well under 10,000 miles. Reported from a few hundred miles to about 100,000 miles, with many of the earliest reports under 10,000 miles.

   What to check: Test-drive from a stop and from low speed and watch for delayed or flaring shifts, and ask for the transmission service history. A service bulletin describes a relearn procedure and one addresses a 2-3 upshift shock, so ask whether either was performed.

   “I went into kroger's and picked up a few items. When I was done, I left the store and got back into my car to finish running some errands. I started my Kia- Spectra and she purred like a kitten- as usual. I put my car in reverse to back out of the parking space but my Kia would move. I was pressing the peddle and my car did not move. I could hear the car revving up but I wasn't moving. …”

   NHTSA complaint #10466757, filed 2012-07, 100,932 miles

   “On several instances my car has not shifted into a higher gear when taking off from a stop sign. I have taken the car to the dealer twice and they have not found anything wrong. This has happened on the following dates: 9/11, 9/12, 9/20, and twice on 9/23.”

   Vehicle speed control

   Sudden or unintended acceleration and high idle

   • 16 complaints (23%)
   • median 36,000 mi at 4.0 yrs old (13 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2004–2022

   Owners describe the engine revving or the car accelerating without a corresponding pedal input, sometimes while slowing for a light or when the brake is applied, and in some cases the driver had to shut the engine off to stop it. Related reports describe the engine racing at idle or stalling and revving alternately, and several say the dealer could not duplicate or diagnose the condition. In a few accounts the transmission lunging into gear and the engine surging were described together. Mostly reported between roughly 1,000 and 60,000 miles, with some later reports beyond that.

   What to check: Drive the car at steady and low speeds and check that idle is stable and that the pedal and brake respond predictably. Ask whether any throttle-body, idle-control or engine-computer work has been done, and note that intermittent reports are hard to confirm on a short test drive.

   “While driving and upon pressing the brake pedal down, the vehicle surged forward. Consumer took the vehicle to the dealer eight times. Also, there was vibration in the steering which made a banging noise.”

   NHTSA complaint #10092639, filed 2004-09, 900 miles

   “The car will suddenly accelerate while driving. It will also lunge when shifting into gear, forward and reverse. It does not occur everytime the vehicle starts. We brought it to the dealership twice for this problem. The first time they said they couldn't duplicate the problem. The 2nd time they said that it is normal for RPM's to go up when the engine is cool. When the car lunges, the brakes have to be depressed as hard as possible to stop the car. It sounds like the same problem they had with the Kia amanti.”

   Engine cooling

   Engine hesitation, sputtering and stalling

   • 6 complaints (8%)
   • median 19,150 mi at 2.4 yrs old (5 state mileage, few)
   • filed 2005–2011

   Complaints describe the engine sputtering, hesitating or losing power when the accelerator is pressed, and in some cases cutting off while driving or nearly stalling at highway speed. Several owners report multiple dealer visits where no fault was found, while others mention check-engine codes traced to an oxygen sensor or a fuel cap sealing problem. Some reports pair the stalling and revving pattern with work on the transmission solenoid. Reported from a few hundred to about 66,000 miles, including several cases under 20,000 miles.

   1 related service bulletin

   What to check: Ask whether any stored engine codes have been read and cleared, and whether the oxygen sensor or fuel filler cap has been replaced. A test drive that includes a short highway merge helps reveal hesitation or power loss.

   “Kia Spectra ex 2004.5. Constantly stalls and engine races at any time and any speed. I am forced to place transmission in n when I aproach a stop sign. I avoid highways being afraid to stall at a high speed and cause a fatality to myself or another vehicle. Problems started when vehicle was still under warranty. In a typical Kia fashion I was told nothing was wrong.now out of warranty situation has got worse.my mechanic says is a design defect in the computer system or the fuel system. …”

   NHTSA complaint #10421665, filed 2011-08, 55,600 miles

   “My vehicle sputters while driving. There have been a few incidents where my vehicle has almost stalled on the freeway while I was driving in fast lane. I have taken my vehicle to the dealer at least 5 time in a 2 month window, and they claim that they cannot find anything wrong with my vehicle, so they are refusing to fix my vehicle or take all of the precautionary measures to repair my vehicle. …”

Buying note. These reports center on transmission shifting behavior and air-bag warning lights, so a careful test drive and a check of recall and service-bulletin history matter more than cosmetics. Because many owners say dealers could not reproduce the symptoms, ask for any prior repair records and have a pre-purchase inspection look specifically at the transmission, air-bag system and underside.
