Selected complaints filed with NHTSA by 2004 Kia Spectra owners, lightly cleaned up (personal details are redacted by NHTSA).
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.
Tamara recall; there was an accident about ten cars in front of me. I seen everyone start hitting there brakes so I started applying mine. Then I realized everyone had come to a stop so I applied on my brakes even harder and they locked up and I slid about 15 ft. And hit a truck in the rear end still going about 35 MPH. It shoved the front end of my car back quite a bit but yet my airbags never deployed.
Dt: the consumer's attorney stated that during a frontal crash the airbags did not deploy. There was a front end collision into three cement culverts. There was a police report filed. The consumer's son was driving and he passed away. A lawsuit was filed against the manufacturer, but they did not have any information as to why the airbags did not deploy.
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.
We were involved in an accident our seat belts and airbags failed to work. We were both thrown into the windsheild . Suffered injuries to back, head and neck. Transported to hospital by ems. Our vecicle 2004 Kia septra 4 door was a total loss.
Dt: the contact's daughter was driving at 40 MPH and she ran a stop sign. She hit another vehicle head on. Upon impact, the air bags did not deploy. Seat belts were in use. The vehicle was totaled. The manufacturer was contacted.
Black ice on roads I ended up turned upside down in a six foot ditch. Car has been totaled. No air bags deployed. Upset that a crash like that the air bags would not deploy. What is the protocol for something like this?
Front end collision, airbag did not deploy. 2004 Kia Spectra. It was hit by a truck at approx. 55 MPH in the left front corner pushing everything into the motor area and the airbag did not deploy.
The warning light on the Spectra 2005 4-door has been a problem from day 1. The light keeps going on and off. When I brought it back to the dealer on a number of occasions, the light went off so they were never able to determine the problem. Now the light is permanently 'on' and I don't know if it is working or not. It is definitely a concern and it is a definitely a problem. In addition, the timing belt keeps loosening on a continual basis. I have repeatedly bought it to my mechanic to get it tightened. This should not be the case. The timing belt, once fixed, should remain in tact at least for a length of time (not a month!). That the warranty has expired, the light remains on. Whatever, I have been very unhappy with the car. Am disappointed. …
Warning light for airbag on the speedometer panel stays on. Dealer and Kia tech first replaced passenger seat cover and drivers side seat buckle because they were shorted out. This did not solve the problem. They then said the problem was because of some fluid spilled on computer under cup holders in the center council. (why would anyone put a liquid sensitive product under a cup holder?) they stated that pin 3 on the computer connector was shorted out. I then pointed out that pin 3 was a ground pin. Kia has had massive failures with their early airbag systems and have refused to fix an item that was the bases for choosing their product. Kia has since introduced a new airbag product that seems to work flawlessly. This new product should be offered at no expense to those of us that were provided a inferior and unsafe product.
