Howdy, folks! My wife and I just got two new Kia Sedonas to replace a '95 Mercury Grand Marquis and a '99 Ford F-150. Both were beginning to fall apart, and the truck was overheating at highway speeds. So far, so good on the new mini-vans, but I would like to hear about any problems you guys may have had with yours. I do contracted delivery of auto parts to dealers - averaging 300-400 miles of driving every day. At this rate, my warranty will be expired before long, so it would be nice to know what to expect. Of course, in return I will post any problems I have with my Kia as I put some heavy mileage on it. Thanks!

Okay! It's been 4 weeks in our new Kias, and I must say I'm pretty impressed! I've put 7500 miles on mine, and my wife has 1200 on hers. So far I have only two complaints: tires and legroom. The tires slice through rain and puddles like a knife, but they have developed a vibration. They can't be flat-spotted, although I suppose I could've slung a wheel weight. Legroom, just have to get used to it, I guess.

My 2003 Sedona also had wheel vibrations. We discovered that the wheel lug nuts were coming loose and cause the wheel to whobble. This has happened twice in 14,500 miles.

Our Kia Sedona has been to the dealer 4 times this summer with the Check Engine Light problem, and other misc stuff breaking or stoped working. And only has 36k miles.

What do you mean legroom - I'm 6'2", 280lbs and the Sedona has much more room than the Ford Galaxy (I think you call it something else with you). Also, it's the only people carrier that I can walk through to the back seats without having to disembark! :lol:

One of my tires, wheel etc has been destroyed to the tune of +-$800 because of this problem. My local dealer is telling me that this could not be their fault or the fault of the vehicle. What did your dealer do? (2002 Kia Sedona)

194000 mile update

Okay. I now have over 194,000 miles on my Sedona. 3 weeks ago I pulled off the timing covers to replace the timing belt and water pump. This was to be its first replacement. Now, the manual recommends this to be replaced at 60K intervals, but I have always believed that time hurts a vehicle a lot more than miles do. The wear indicators on the timig belt showed no signs of deterioration and the writing on the back of the belt was still very legible. BTW Gates makes Kia's timing belts ;) I did NOT replace it. "If it ain't broke, don't fix it." This is not to say I haven't had other problems, though.

Evidently, Sedonas have an inherant design flaw in there suspension. Specifically the struts and mounts. Annoying vibrations are heard at the least little bump. Sometimes it seems the smaller the bump, the louder the vibration. I know how to fix this: relocation of the strut and mount... but I'm no front-end specialist therefore I don't know where to drill the holes to do this. Any clues anybody?

Also, the front right wheel bearing separated this past weekend. I replaced it twice in one day only to have both of them separate within the first 4 miles of the test drive. So I was thinking I just wasn't holding my mouth right or something. I took my hub assembly to one of the few mechanics I trust that has a press to replace the bearing for a third time and he pointed out significant wear on the back end of the studded hub spindle. This is the part that the CV shaft slides into. The CV and the spindle turn at a 1:1 ratio because of the splines that interlock to turn the wheel. How can there be wear there? Whatever the cause, I am now going to have to replace the spindle. A local junkyard has a whole hub assembly for $75. I think that's how I'll go, because Kia's list price is $96 just for that spindle.

194,000 miles and the only other problems I've had have been only brakes. Aftermarket rotors warp very easily. The rear (drum) brakes lasted till 180K, but the aftermarket lists 789 as the part number for the shoes. Nope.... not right! I had to order them from Kia. $79 list on those jewels. $63 if you qualify for a discount, but still steep for shoes.

SeaFoam has been the cleaner of choice for the inside of the motor. I still have the original spark plugs!!

Sheesh you;ve put some mileage onto your motor very quickly!

Thanks for the update and how much more mileage will you put on your Sedona before you think of changing?

Is the 3.5 V6 an interference engine? If it isn't you just made my day by telling me you have 194k on the original belt.

My original spark plugs were very worn at 55K miles. I replaced them with platinums (OEM's are not platinum.)

Brake rotors were a pia to change because of the bolt/phillips screw that secures the rotor to the hub...which I had to drill out.

Gas mileage is pretty poor (~15 mpg)....why did you choose the kia for heavy useage?

re: 194000 mile update

Ok, let me add this: just because I have 194K+ miles on mine doesn't mean that that is typical. I am a firm believer that time plays a more critical role in the failing of components than mileage. But that will only hold true for certain things. In theory, as long as the belts, incl. timing, are the proper size and tightened to the proper tension, they should last a couple of years. I DID replace the alternator and power steering belts at the time I checked the timing belt. They needed replacing! But there are a few things where mileage is more important than time.

Bearings are the first thing that comes to mind, and that's also something I forgot to mention earlier. So far the ONLY wheel bearing that I have NOT replaced is the front driver's side bearing. All the others have already bit the dust.

Brakes is another. And boy have I had a time with front brakes! The aftermarket rotors are nearly 1/4" thinner than OEM. At first I had concerns about running the rotors to their minimum (stamped on the rotor) and pads to the metal... worried that there might be so little there that the pistons in the calipers pop out, but that hasn't happened yet.

And of course, TIRES! YIKES I have gone through some rubber there! But I guess thst's mainly due to the problems with the struts. Oh well.

All things considered, though, the Sedona was a good choice for me. It still cranks up and works like a dog all day long and doesn't complain one bit.

Thanks, Inky! I haven't had any of those problems, yet, on mine, however the point about the inaccurate fuel guage reminds me that my wife's van does that. We're not worried about it, because once it gets below halfway, the guage then seems to be pretty accurate. The light comes on about a gallon too early to me, but that may be simply a slight difference between our two vans.

It's wild how you can have two very similiar vehicles, both of them (I assume) treated well-- one develops a myriad of problems and the other runs like a champ. Happens all the time. I just wonder if you could track things back to Day One, if there would be a point where you could say, "Ah, that's the difference right there!"

Everything considered, I think I'm fairly lucky that my van has only had the problems it did! Even this morning I know I'll put about 120 miles on it before I get back. I used to have other vehicles where I had to say a little prayer before I turned the ignition, but this one has never stranded me or even made me do emergency repairs on the side of the road (except for flat tires). So far, everything repaired was done with the parts already purchased and the time to do them set aside, dedicated to do the repair.

As far as my wife's Sedona with a whopping 37K miles goes, oil changes, washer fluid refills, wiper blades, and one pair of tires replaced on the front have been par for the course. I've stopped trying to compare the two vehicles a while back.

No matter how identicle two cars are when they roll off the assembly line, time, miles, and different drivers have turned these two vans into two completely different machines. They drive very differently. My steering is loose where hers is tight. My brakes always seem to tremble a bit (because of those #$%^& warping aftermarket rotors) while hers is solid. Hers smells like stale, buried/hidden french fries and melted-from-the-sun crayons, where mine smells like cardboard, newspaper ink, and cigars. Too many subtle differences that only we would notice, but they're there.

Day one differences, though... her gas hand. The dealer and we both thought they simply didn't fill up her tank when we took possession of the vans. Nobody knew at the time about the problems Sedonas have with the guages, but all this led to was another free tank of gas a few days later. :)

All in all, $31,000 was pretty good, I think, for two - TWO - minivans!

198,000 miles

198,000 miles and a few new developments. There has started a slight tick in the engine. It sounds like a valve tapping. I added a bottle of STP Oil Treatment just to put something thick in there until the oil change. This was at around 196k. This past Monday I flushed the engine and performed an oil change substituting one quart of my regular oil (Motorcraft 15W-40) for one quart of High Tach. This calmed the ticking down about 75%, but it is still there.

Also, there is a hard-start condition developing. (This is where the engine will crank (turn over) at its normally great speed, but will not actually start running after only a couple of spins.) I have narrowed the problem down to fuel. Here are the possibilities: 1) a fuel injector is leaking down. 2) the fuel pressure regulator is allowing the fuel to flow back into the fuel tank and not keeping the fuel rail pressurized. 3) the seals in the fuel pump are allowing the fuel to leak back down into the fuel tank and not keeping the fuel rail pressurized. I have yet to perform a pressure test to see the actual pressures, but I think this will only confirm the leak and not tell me which component is failing. Has anybody else experienced this? My occupation puts me in close contact with many mechanics and repair shops on a daily basis, but NONE of them know much at all about the Kia Sedona. It would seem that with my job I am running into uncharted territory since nobody around here has any of these cars with this many miles.

Of course I could simply just start replacing things like the fuel pump, injectors, and pressure regulator, but this can get quite expensive to do!

And does anyone know if there is a maker of cross-drilled rotors that supply for a Sedona? I have bought, machined, and worn out several rotors over the past two years. I am kinda tired of the front right rotor warping after only 1-2k miles.

203,500 mile update

200k must be the breaking point for the Sedona. All hell is breaking loose. LOL. The check engine light has come on and went back off (!) 3 times since it turned 200k. It has developed a rough idle, but it's not skipping. I checked everything out under the hood to make sure no vacuum lines or electrical connections have not come loose. I will probably hook up a code scanner this week to retrieve the codes that have been set. I'm sure it's probably something simple. I'm keeping my fingers crossed.

About the front struts making so much noise, Moog lists mounts for the Sedona, but so far I can't find any aftermarket struts. I'm thinking of using struts and mounts out of a Dodge Caravan or Ford Aerostar to replace the ones in the Kia. It shouldn't be a hard process, but I believe doing this will result in a more reliable and cheaper alternative to getting the struts from Kia that may end up causing the same problem all over again. Crossing over the struts will be easy, but I would really like to change over the braking components, as well, but I'm afraid that I won't be able to find a hub assembly that will be compatible with the lower ball joint and outer tie rod end. Any thoughts on this, folks?

Interesting reading your thread on the sedona, and the differences between time and mileage. Have to agree that they do different things to a car. I was interested to note you used the seafoam. Thinking of using it myself, how often do you use it time/mileage.


Hope you find out what those codes are.

Look forward to your responses

BTW, I know that someone lowered the van slightly which did make a significant difference to the suspensions problems of the car

1st code: restriction in catalyst, bank 2
2nd code: mass air flow

OMG! Did anybody know that there are THREE catalytic converters on the Sedona?!? A preliminary check on Kia's website revealed not only that, but they are listed at $1200 each! The two that are placed before th Y-pipe are also positioned and made in such a way that they can't be "straight-piped". Ugh! I was looking at the assembly yesterday. It seems in order to get to the bank 2 converter the starter and the top radiator hose assembly have to be removed to get out the corresponding exhaust manifold. (Bank 1 is always considered to be the manifold that is attached to the number 1 cylinder, which, in this case, happens to be the bank closer to the firewall.)(<--- FYI) At any rate, it looks like I have my work cut out for me!

The mass air flow code could have been set as a result of the restriction of the catalytic converter, so I'll fix the converter first and wait and see on the MAF.

Seafoam... fantastic stuff! When it's used properly, it can make an engine run like new again... well except when there is a cat-conv restriction...LOL. They basically make three products: Seafoam, Deep Creep, and Bug-B-Gone. All of it is top-notch stuff. The Deep Creep is basically Seafoam in a spray form. The name suggests that it is merely a rust eater or something like that. I does do that, but so much more. And the Bug-B-Gone is also great as a car wash and general cleaner... for the inside, too!

Ouch! It really does sound like you have your work cut out for you. At least your wallet will be lighter so you don't have to worry about being weighed down. :eek:
