2007 Kia Spectra Problems

What owners report

Owners of the 2007 Kia Spectra most often report the front passenger air bag indicator staying lit or the occupant sensor mat failing, frequently accompanied by a repair estimate in the four figures. A second common theme is stalling and rough running that begins right after refueling, and door locks that cycle on their own. Many complaints were filed years after purchase on cars with well over 60,000 miles, and the air bag items in particular often appear to develop gradually rather than suddenly.

1. 1
   Air bags

   Passenger air bag light on / OCS sensor mat failure

   • 38 complaints (25%)
   • median 86,400 mi at 7.4 yrs old (33 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $1,400 (median of 5 quotes)
   • filed 2008–2024

   Owners describe the passenger air bag indicator staying illuminated or switching to off even when an adult is seated, sometimes from the day the car was new. Many say a scan returns code B1448 and a dealer or shop identifies the occupant classification sensor mat under the passenger seat as the cause. Reported repair quotes run from roughly $1,100 to $1,500, and several owners say the dealer could not reproduce the problem or suggested sitting differently in the seat. Reported from near-new mileage up past 160,000 miles, appearing at any age with no clear weather pattern.

   What to check: Turn the key to run and watch the passenger air bag light with an adult in the seat, and ask whether the OCS sensor mat has been replaced or covered under the extended warranty on this part.

   “I have always had a problem with the passenger side airbag light, no matter the weight of the person it sometimes says its off. Have taken it to dealer and they have no solution, they cannot even diagnose it because there is no error code stored. This is supposed to be a safe car and it scares me to even drive with a passenger. Need to have a recall.”

   NHTSA complaint #10626906, filed 2014-08, 12,500 miles

   “Our vehicle failed inspection due to the air bag light being on. When diagnosed, code b1448 was found, indicating that the occupancy sensor, part of the seat sensor mat (on the bottom of the seat), was faulty. We are concerned both about the safety of driving our car, and the high cost of repair. It seems that this is a widespread problem, and we believe that Kia should recall the part.”

   Fuel system

   Stalling or rough running after refueling

   Mentioned in 11 of 60 sampled complaints

   Owners report the engine dying or hesitating shortly after filling the tank, sometimes repeatedly at stop lights until enough fuel is used. Several mention a strong fuel smell, fuel leaking, or the tank only accepting fuel until the pump shuts off. Some describe dealers replacing fuel system parts or being unable to pinpoint the cause after multiple visits. Mostly reported between about 46,000 and 90,000 miles, typically within a short drive after a fill-up.

   What to check: Fill the tank during a test drive and see whether the car idles or restarts cleanly, and check for a fuel smell around the filler neck and under the rear of the car.

   “My 2007 Kia Spectra stalls out every time I fill the tank. It stalls during high rate of speed and during normal low speed driving. My Kia is out of warranty, and from what I have read on other sites it would be a waste of time to have it fixed. Also I had to replaced the stop light switch under the dash. The recall was with 5 Kia models but not the Spectra.”

   NHTSA complaint #10357729, filed 2010-09, 65,000 miles

   “Reporting 3 issues: ***fuel system: in july 2009, one month after I purchased my used 2007 Kia Spectra (46k miles), the vehicle stalled at idle/low RPM while in traffic on an interstate highway. Once restarted, it continued to stall at every idle until a significant amount of fuel was consumed. Almost 5 years later, the problem is ongoing. Stalling occurs if the fuel tank is filled (to the point of automatic pump shut-off). The tank has never been topped off . …”

   Latches, locks and linkages

   Doors locking or unlocking on their own

   • 16 complaints (11%)
   • median 28,000 mi at 3.8 yrs old (11 state mileage)
   • filed 2008–2021

   Complaints describe doors locking and unlocking repeatedly without input, both while parked and while driving, and sometimes the driver door relocking right after being unlocked. Owners report keys being locked inside, and some say dealers could not duplicate the problem or replaced the door lock module or mechanism. Reported from very low mileage (under 3,000 miles) up to about 60,000 miles, in any weather, often after the car has been owned for a few years.

   2 related service bulletins

   What to check: Lock and unlock the doors several times with the fob and the door switch and watch for any cycling, and ask whether the door latch assembly has been serviced.

   “While filling up with gas, I heard a distinct click and upon looking saw that all of the car doors had locked. My keys were still in the ignition. I called the road service that is associated with the car and they had it open almost immediately for me. The doors have locked independently a few more times since then while I have been driving down the road. Approximate mileage: 17,000.”

   NHTSA complaint #10238694, filed 2008-08, 17,000 miles

   “The door locks have gone haywire. They click on and off automatically whether you are driving or if the engine has been turned off. Had to break the lock on the driver's side in order to exit the car. Passenger side will not open as well even via using a key in the door lock. This is an extreme safety hazard! Contacted Kia a month ago, they never got back to me. I have seen on the internet where other Kia owners have the same problem.”

   Vehicle speed control

   Engine surging or revving at idle and low speed

   • 12 complaints (8%)
   • median 38,000 mi at 6.3 yrs old (10 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2009–2023

   Owners report the engine revving up or the car surging forward while stopped with a foot on the brake, and in some cases elevated RPMs with little forward power. Dealers in the complaints often could not determine a cause, and one owner describes a transmission-related software update mentioned online. Reported from about 2,500 miles to over 130,000 miles, typically at stops or low-speed driving.

   What to check: During a test drive, sit at a stop in drive with the brake held and watch the tachometer for a rise, and ask whether any transmission control software updates were applied.

   “I was driving on the highway when all of a sudden the check engine light came on and I lost all power in the gas pedal,( you can floor the peddle and it don't go over 2000 RPM ) almost resulting in a collision. It only comes on when it want to, I had the codes checked at auto zone and they said its saying all the solenoids are bad. …”

   NHTSA complaint #10593224, filed 2014-05, 65,000 miles

   “When stopped (for example at a stop sign), with the car in drive and the engine running, the engine will sometimes go from idle to a higher speed (it accelerates). My foot was not on the brake and gas pedals at the same time and this is not an issue with the floor mat. (I know because I looked.)”

Buying note. If you are considering a 2007 Spectra, budget for the possibility of an occupant sensor mat repair and ask for evidence it was already handled, and test the door locks and a post-refueling idle before committing. Check that the fuel tank mounting recall was performed for the car's registration state.
