Fuel Tank Air Filter / Fuel Filter

[xiaphin]

The written response from Hyundai corporate was that it is important AND by not following the Hyundai recommended service I might void the warranty.

Do you have a copy of this letter and how did inquire with corporate about the filter service?

Regarding the fuel filter and fuel tank air filter, your dealer is absolutely wrong. Read the manual regarding services. I have 162,000 miles on my 2011 Genesis and no problems. Not replacing the fuel filters can cause fuel pump problems. Your dealer obviously lacks trained techs and lacks knowledge of proper maintenance on luxury cars.

I just scheduled my 60,000 mile service and was also told that the fuel filter and fuel tank air filter is not required. Not only that but not replacing them will not effect my extended warranty if something were to happen down the road. Feel like this is something that I need in writing.

This is a big deal to me because of my air ride system, if they had to be replaced I would need to temporarily remove the tank and compressors to provide access. Came up with a makeshift manifold that would work for a day but needless to say it was a relief when they said not required. I pointed out to them that the manual states to change these at 60k miles. Dealer told me they don't replace them unless they are fixing a problem that already requires them to go into the tank.

Side note shouldn't they be able to provide me with a list of all the service that has been performed on my car even if done at other dealers?

I finally got around to changing the fuel tank air filter. My 2012 5.0 has 51k miles and the fuel tank air filter element looked grey instead of the clean white. The installation is a PITA, especially for a 6'6" 250 guy like me. I did find that if I removed the spare, I fit more comfortably in the trunk.

Do NOT buy the part at your local Hyundai dealer. They wanted $41 plus tax, and online was only $26 plus $5 shipping.

My charcole canister (next to the fuel tank filter) has a label on it that says Oct-2014 (roughly 26k). I'm guessing that it will be good for at least until 60k miles.

This was the first time that I have worked under the back of the Genni, and I must say that other than a flimsy stabilizer bar for a 5.0, the rear axle housing is mounted solidly in the sub-frame, and the half shafts are beefy steel.

I truly love this car, and it's little quirks, clicks, and character.

Your dealer is full of BS. Its in the manual to change the filters and I have had the service done several times per the manual. My Genesis has over 184,000 miles on it and I want to keep her running like new as long as possible. A clogged fuel filter will make the fuel pump work harder.

My dealership states that Hyundai manual is misguided, the replacement called for is the CCV or Canister Close Valve. It is one of the main reasons gas flows slowly at the pump. I am clanging mine soon.
Part is about $70.

CCV and fuel filter serve two completely different needs of the car.

I called about 5 dealers to ask about this and they all told me it wasn't required to be changed. Opted not to get it changed because of my air ride system having to be removed in order to do so. However I hope it doesn't cause an issue from not being changed.

One of the two dealers I go to recently had the car in for a 24 month service yesterday.

My 2010 Genesis 3.8 has only 11,300 miles on it. I asked him about the fuel tank air filter and he said that in general they do not replace them, and ditto the fuel filter.

I am growing increasingly concerned about the disconnect between Hyundai dealers and Hyundai's own service manual. My service writer said that you could drive the car 50,000 miles and that air filter would still be clean. He quoted me a price of over $200 to replace it.

One has to be careful. Will Hyundai void your warranty if you have a major engine failure, EVEN IF this item had nothing to do with it?

It might be (I am not saying it necessarily is) that this flat rate item has a low profit or even a loss to dealers, and so they are more interested in pursuing high volume high profit oil changes than they are fuel filter replacements.

An alternative interpretation is that the service writer knows these items are hugely over-engineered yet difficult to replace, and is trying to save the customer money.

Which brings me, once again, to a fundamental question. WHY, given the fact that this is a premier forum in North America for Hyundai Genesis owners, isn't Hyundai actively monitoring this forum and providing some guidance to us??

You re assuming that the tech's and service writers are well trained. I found that most dealer techs don't know how to replace the fuel filter or the fuel tank air filter on the Genesis. They also did not know that the ZF transmission in my 2011 Genesis has a trans. fluid filter made into the pan of the transmission. One tech even told me that my car has no transmission fluid filter and his service manager backed him up on it. I never went back to that dealer.

I have 60K miles on my 2012 Genesis and my dealership said they don't replace the fuel tank air filter (canister vapor filter) becuase they end up breaking the canister itself (sounds like BS to me). Since it was suppose to be replaced twice by now I went ahead and ordered one and hope to put it on my self in the next couple weeks.

The fuel tank air filter is not under the hood. The dealer service techs are nuts. The fuel tank air filter as I recall is accessed from the trunk.

Hood? Where did you read hood? Yes it is accessed from the trunk.

Just thought that the dealer was confusing parts.

 

[OUsig]

I have many of these parts available if you are interested off my 2013 Rspec. I purchased new ones (my own dumb self) trying to self diagnose a check engine code. Figured out it was the purge valve on the engine the whole time.
So I have the original charcoal canister, fuel tank pressure sensor and vapor canister vent solenoid.
send me a PM if you could use these

I don't think the dealers have mechanics with enough expertise to do this, and if they make a mistake with the fuel system it could lead to disaster and lawsuits. I am not surprised they don't recommend it, and I agree that a sensor would likely come on if there was a problem.

2009 127K I am having an issue with my car starting intermittently. The dealer replaced my engine control module after 9 days of searching, indicating my fuel pump was not grounded? Then the dealer recommended replacing all of the emission parts. A non-dealer mechanic found the Fuel Vapor Valve cracked. PO456 was the code and we have replaced it. The car is still having issues. My dealer has no idea what's wrong with my car. What fule codes will the computer detect? I will report back with more from Hyundai Corp.

 

[memphiskane]

Probably not related but I have had 2 intermittent starting issues in the past 4 years. Both times the starter needed to be replaced on my R-spec. First one the dealer did under warranty, second I went non-oem but same OE supplier. Had napa test it off the car the second time and it was drawing more than double what it was supposed to. I seem to remember 80-85 being the number but napa rated the draw at closer to 170.

Oh and it threw no codes for this

I just stumbled onto this thread, found it to be very interesting. I bought a new 2018 G80 sport and was just reviewing the maintenance schedule, at 30,000 miles it calls for an "inspection" of the fuel filter and an "inspection" of the fuel tank air filter. Both items have an * after them, the * notes that "These filters are considered to be maintenance free but periodic inspection is recommended for this maintenance schedule depends on fuel quality". It goes on to say that if engine surging, loss of power, hard starting etc.... replace the fuel filter immediately regardless of the maintenance schedule.
