2004 Kia Rio recalls 2

Recall repairs are free. Your dealer fixes them whether or not you bought the car there - check your VIN at nhtsa.gov/recalls to see if yours is done. What to do

Child seat

05V55700090,865 vehicles affected

The problem
Certain passenger vehicles fail to conform to the requirements of federal motor vehicle safety standard no. 225, 'Child restraint anchorage systems.' Certain child restraint anchors will not fully latch onto the lower latch anchors located between the rear seat back and rear seat cushion because of interference between the child seat anchors and a metal wire located in the frame of the rear seat back. Until the recall repair is completed, follow the instructions provided by your child seats manufacturer on how to properly install the child seat with your vehicle's rear safety belts rather than using the latch system.
The risk
In the event of a vehicle crash, if the child seat is not properly installed, personal injury or death could occur.
The fix
Dealers will replace the lower anchors free of charge. The recall began on january 30, 2006. Owners may contact kia at 1-800-333-4542.

Fuel system: delivery

04V179000187,790 vehicles affected

The problem
On certain passenger vehicles, the fuel intake nipple of the fuel distributor is subject to fracture or cracking during removal of the quick connect coupling securing the main fuel tube assembly to the fuel intake nipple, or when force is accidentally applied to the intake nipple during the vehicle assembly process or during engine compartment repairs.
The risk
Fuel leakage in the presence of an ignition source may result in a fire.
The fix
Dealers will replace the fuel distributor and main fuel tube assemblies. The recall began june 18, 2004. Owners should contact kia at 1-800-333-4542.

Electrical system

I bought this car used a little less than a week ago. There was a thumping noise under the hood so I took the car to the dealer twice for this issue. I looked under the hood tonight and found a bunch of pieces that are not bolted down and the battery is completely unsecured and can move around freely. It's horribly unsafe because the battery being loose can affect the entire car and the parts that aren't bolted in place are causing major issues with the AC and other systems.

My wife got locked in her car in the garage at home. There is a spring on the door latch that holds up a lever, that broke, causing the lever to drop and jam the lock lever. When she tried to unlock her door it would not release and the auto lock function kept the other doors locked too. We were able to use my key to quickly unlock and open the passenger side door and get out by crawling over the center console. A simple google search found a few thousand entries showing this same issue with other kia rios and optimas where people are getting stuck in their cars.

Driver side door lock does not always work. When locked from inside the car you have to crawl out the passenger side and go around to driver door, put the key in the lock and wiggle the inside door lock lever. Sometimes it takes minutes to get it to unlock. If you were to have to exit the vehicle quickly it would not be possible. This has happened multiple time in this car.

a hammer on the axle produced a hole of about 1" a second tap & it too came off the car. I removed both shocks & the car is now no longer safe to drive. So, it's a total loss which is not covered under insurance. I see where kia has recalled the 2004 optima for a rust out issue with its subframes. (Sc 075 june 2009). The recall should also include these vehicles as well. Upon further inspection the rear brake drums are also rotting out leaving a gap on top where moisture can get to the inner workings of the brakes. The rear lateral arm mounting nut is not identifiable due to extreme rust. Both rear spindle assemblies are also rotting so badly from behind that the bolts used to secure them have no heads just rust. The rear seam of the gas tank is also rotting out. Finally the front suspension & underbody also has severe rusting issues. The car was purchased new in nj & has spent it's entire time with me at my home. At time of purchase the dealership, salerno kia of newton , nj ( no longer in business) "rustproofed" the underside of the car which cost me several hundred dollars extra. *Tr

The car caught on fire, kia says they sent a notification to the original owner, years ago. We feel that we were entitled to a recall notice before the car burned down. We feel this is not a small recall, it was a fire, a fire is very dangerous and can burn and kill people. We had 22 kias rios in our fleet and never received recall notices on any of them. Kia did send notices to the original owner however they had the information as to which cars received the recommended repairs and which cars never came in, there needs to be some follow up. *Tr

Our car caught on fire. Kia says that recall notices were sent out to the previous owner to take the car to a kia dealer for repairs. Notice was sent out years ago (2002). Kia knew that the repairs were never done because no dealership had billed kia for repairs. For nine (9) years this car was on the road without a safety recall being performed for fire. For nine years we registered this car and kia made no attempt to find out who owns the vehicle. Kia is being very unethical because they say that a notice was sent out (one notice) and now they have done their obligation. *Tr

rio we also bought a kia spectra. So of course we took the spectra in right away to get a new belt so we wouldn't have 2 cars down. That cost 677.00. I had 78,000 on the spectra and there was 83,000 on the rio. I investigated this problem come to find out alot of people had this problem so kia knows about it. I then checked the technical bulletins and found that in january 0f 2005 there was a bulletin item number 10015272. It says they improved the timing belts for the kia rio and optima. Well they didn't improve it for my car. When the timing belt went it blew the engine. We are so made and when we took my spectra in to be done and told them what happened to the rio they said that's to bad. We now have our car at another garage and are trying to get kia to pay for another engine. What do you think my chances are? I am at work now and I do not have the vin number, if you email me then later tonight I can forward the vin number to you. *Tr
