Is it really necessary to replace the O2 sensors at 45,000 miles as stated in the maintenance list? Don't most sensors last much longer, and isn't the normal procedure for most vehicles to wait until they fail or get slow as indicated by the PCM throwing a code? Well over $400 for parts that really are not needed seems a little steep. Granted, I am nowhere near that mileage, but what other little surprises await us?
No, it isn't necessary to replace your oxygen sensors at 45k. Nor is it recommended by Hyundai. I'm not sure what maintenance list you're looking at (possibly you're dealer's wish-list), but oxygen sensor's are not on Hyundai's maintenance schedule for this car anywhere.
You should probably get out your owners' manual and look through the maintenance schedule there and compare it to whatever load of crap you're currently using as a maintenance guide.
And you've got the oxygen sensor idea correct. Once one causes a check engine lamp to illuminate, then it's time to replace it.
Okay, well I'm definitely confused. I looked at a Sonata owner's manual and it's definitely not in there.
the Hyundai site that Bob mentions also shows replacing the FUEL TANK AIR FILTER that I have been asking about that no one sems to know about, but dealer where I tried to order the fuel tank air filter, said that it involves revmoing the tank and the dealer has to do it....another dealer gouge??
Another dealer gouge? What should the dealer do - provide you with written instructions on how the home-owner can drop the tank and repair it himself in under 1 hour as if this were an HGTV episode? It's an '06. Why are you not just taking this to the dealer for warranty work?
I have been building/rebuilding cars for 40 years and there is nothing that I haven't done, including changing tank fuel pumps. rebuilt lots of engines , differentials and trannys. I can change plugs, oil, tranny fluid etc. As far as I'm concerned the dealer is there to provide the warranty service and sell cars.
I'm mostly just confused on this. The address linked in Bob's post is the Hyunda USA official website. I don't understand why the requirements there don't match the owner's manual. I suspect they have put in another country's maintenance requirements (maybe they don't have the same sophisticated electronics that can monitor the oxygen sensors for failure) and also translated very poorly out of whatever language they were written in. Fuel tank air filter? What the heck is that, anyway?
Who are you replying to? Including the text you're replying to makes it a heck of a lot easier to understand your point.
So - you've worked on cars for as long as a lot of us. Then get brassy and drop the tank. Should not be that hard.
As to dealers and warranties... I asked in a previous post - why aren't you just taking this to the dealer as a warranty repair? Your reply is that dealers are only good for warranty service... Ok - I'm confused.
warranty repair is one thing. service to maintain the warranty is another. If they require oil change, brake inspection, air filter change. thats not warranty repair. that is service to keep the warranty in force.
There really does appear to be such a thing! Hmaservice... Fuel syste > Fuel delivery system > Components > Item #8 It looks like it's mounted up near the fuel filler.

Deck - for cripe's sake - if you don't include the text that you are responding to, no one knows what your talking about.
Service to maintain warranty is nothing new. If you never changed the oil in your Ford or GM car or truck, do you think you'd have any warranty? Hyundai does not require you to have the service performed by a Hyundai dealer - though for some parts they do require Hyundai parts to be used for the warranty on that part to remain in effect - or failures related to that part. Nothing really so unique about that either. Ford or GM don't stand behind anyone else's parts.
I'd like to clarify a bit..... In the US, Hyundai - or anyone else selling a consumer type thing with a warranty - cannot require you to have maintenance or repair work done by anyone specific. They also cannot make you use a certain brand of anything to do that work.
What they can and do do is provide specifications - SP ABDC123 transmission fluid, 10w-30 SUZ motor oil, DOT 9 brake fluid, etc. for things to be used in the repair or maintenance of the vehicle. Now, we all know that the only place that you can buy the Hyundai specified ATF is at Hyundai, Kia, or Mitsubishi dealers, but they are not saying you have to buy it from them. They just say something to the effect that if damage occurs from the use of non-specified fluid, they are not fixing it free. The third party - "can be used in place of Hyundai xxx fluid" - suppliers mostly say that if it can be shown that their fluid broke it, they'll pay to fix it. If you put what they say to in the vehicle's transmission when they say to in the manual, and the transmission smokes at less than 100,000 miles, they can't say you didn't maintain it properly. If on the other hand you decide to do a flush at
10,000 miles and put Type-F fluid in the transmission, and it cooks while it should be under warranty, they get to fix / replace it, and hand you a bill for the repairs, and Valvoline will say it's not their problem because they didn't say Type F works in a Hyundai, either.As for repairs under warranty, things that break that are listed as being covered by warranty need to be repaired by whoever Hyundai says honors the Hyundai warranty - the Hyundai dealer system- or you get to pay whoever does the repairs. Things that break while the vehicle is mostly under warranty that are not covered by warranty - tires, brake pads, the rear bumper if you back into a tree, etc. - don't have to be worked on by a Hyundai dealer. Lets say your left rear wheel bearing goes bad, and you decide get Sears to replace it. You pay Sears (no, I don't know if they actually replace wheel bearings) to do the work. Everything on the vehicle that was under warranty is still under warranty except the left rear wheel bearing. If the left rear bearing goes bad again, it's Sears warranty, not Hyundai's. If the right rear bearing goes bad, it's still under the Hyundai warranty.
Same thing goes for add-ons. If you put a 400 amp alternator in the vehicle to run the thumpmobile amplifier, and the engine throws a rod, as long as you've been changing the oil on time with the right stuff, it would be covered under warranty. If the water pump, or power steering pump goes bad, and they figure out that the 12 inch pulley on the new alternator made the belt tighter, you will be paying for a new pump, and tensioner, and etc. If you leave the non-stock alternator on, and stuff breaks again, you will pay again. If the regulator in the non-stock alternator decides to make 36 volts, and blows up everything electrical in the car, that's not warranty either.
Bottom line... You can work on it yourself - they even say so in the manual. If you don't do what they say to do, and something breaks because of what you didn't do, THE THING that breaks is your problem. I asked about the O2 sensors because if they say to replace them, and I don't, and the care fails an emissions test what would otherwise be Hyundai's problem to fix now is mine - like if the cat. fails because of high HC to the exhaust. Of course, if the O2 sensors are that bad, it will never go closed loop, and it will throw a code long before the cat gets damaged - especially with three in the stream.
That's the filter for the charcoal canister.
