This is typical. When cold starting/running, it takes more amps to run. It is using amps for higher idle to warm up engine, Altenator is spinning faster, and all sensors are being used at same time.
This is why mechanics say wait til normal operating temperature before any testing is done.
Once the engine hits normal temp, the computer readjust voltage amps, fuel pressure, air intake, timing and more.

First I would check your radiator fluid level, sometimes being low can have this effect. Usually the rear heaters sit at a lower level and so keep working. If that is fine, then you probably have an issue with the diversion door or controller that controls the hot/cold mixture.

2003 Kia Sedona rpm running high on a cold start.

If it is around 1200rpm for a few minutes this will be normal as the ECM has set the RPM to compensate for the cold air intake (much like an automatic choke). After a few minutes it should drop back to around 1000rpm and then when the motor has been running a bit drop back to around 850-900rpm. If it not following the pattern then run the fault codes and fix the sensor that is reading incorrectly.

Kia sedona 2003 pr0blem a/c not turn on

The system is likely low on refrigerant charge due to a leak. To confirm this is the case have a local shop hook up a set of AC pressure gauges and read the system pressures. Do not charge the system until the leak is found and repaired.

2003 kia sedona wont charge battery with new alternator

well are you sure that you have a good or it just shows the correct amount of voltage. which that should 12.6 volts for a fully charged battery. to actually answer your question, (assuming)
you do have a good battery your alt. shouldn't keep it from cranking unless it is locked up, but you would use a digital volt meter and select the d.c. volts setting touch the red (positive lead) to the red (positive post) on the battery and the ground ( black lead ) to the ground terminal on the battery (negative post). it should read very close to 14 volts. if not check to see if you are getting voltage to your alt. by using your volt meter to test the power wire going to your alt. it will be the one on the backside of your alt with a protective boot over it. with your volt meter still set on dc volts touch your black lead lead to a good ground and your red lead to your power wire going to your alt. it should have 12 volts there. if not check your fuses. if your car clicks when you try to start it then you may have a bad battery connection. dirty terminals with corrosion built up on them will do the same thing. also a starter that is bad will click because the bendix can't kick out to engage the flywheel to turn your engine over. well hope i answered your question and then some.

I have been advised by a Kia dealership that the battery in my 2003 Sedona is proprietary to the vehicle and that is why I have gone through 3batteries in 3 months. I cannot believe this. Has anyone else...

the battery in the kia is a

group type 55-26 ML
cold cranking amps 600
resserve capacity 113 minutes

its just a standerd battery, i would not return to your dealer, if they would lie to you about this they would lie to you about anything, if you keep having problems with the battery have the charging system tested.

My 2003 KiA sedona,acts like the battary wants to die and then suddenly it starts, has been doing this for 3 days.

1st: Battery needs to be checked (no weak or dead cells) then fully charged.
2nd: If battery is good and fully charged, the problem could be excessive amp draw from the starter, a starter draw test would determine if the starter is drawing too much battery power.
