    It's common in my area (Minnesota) too, except the dealers here don't even offer a "Hyundai recommended" service package. Instead, I have to go through the maintenance schedule with the service writer and have him/her delete any service that is not on Hyundai's list of required services. But the cost difference is about what you described.

    What are some of the extra "Central Florida" services that they recommend at 15,000 miles? One to watch out for is "throttle body cleaning." That isn't necessary and in fact Hyundai even recommends against it.

    Backy is right on about the throttle body cleaning. Hyundai even issued a TSB to the dealers telling them to leave it alone.

    15K service is usually an oil change, external belt check, fluid top off, check the brakes, and that is about it. No emissions testing or other computer based work is performed, at least not in Texas.

    It is unfortunate, but many dealers of all brands have started using these "inspections" to upsell services that may not be needed. On another forum there was a discussion over changing the high capacity air filter in a GM truck. The filter is huge, has an airflow restriction monitor, and in normal conditions can easily go 50K miles without replacement. Probably one of the best non-industrial air filtration systems I have ever seen on a vehicle. And yet, dealers and quicky oil change places will try to sell a replacement every 15K. It is all about profiting from those who do not read the owners manual.

    Another GM dealer was pushing transmission service at 15K intervals. I pointed out to them that under high-temp, towing conditions, GM recommended 30K. And they were charging $169 for the fluid and filter change, a 30 minute job.

    That dealer no longer has a GM franchise. Wonder why?

    OK... I won't even ask how you know that.

    Since you're a long-time Elantra owner, I'm curious as to whether you've ever used fuel injector cleaner.

    I somehow got the brilliant idea that it would help. So I decided that I would use some every 7500 miles. Well I passed 7500 last week and poured some stuff in (Chevron FI Cleaner). Seemed fine I guess.

    About 3/4 of the tank goes by uneventfully, then the Check Engine Light went on (Doh!) I filled the tank, took it to AutoZone for a read on the light: P0172- running too rich- and the AutoZone guy suggests pulling the battery cable to try to reset the light.

    So that's what I did. And the CEL went back out (whew!) So now I've gotten 130 miles out of the first quarter tank; that's usually almost a half tank for me. So now I'm wondering what all happened.

    Was the code related to the cleaner? Was it just coincidence? Did the cleaner improve my mileage, or was it just because of the ECM reset? :confuse:

    For the time being, the car is running better than ever, so I'm just gonna keep driving it. If my mileage is in fact improved, I'll be happy since that's been my biggest beef with the car. If it drops off in several thousand miles, though, the question becomes: Reset the ECM or add more FI cleaner?
  • backybacky Twin CitiesPosts: 18,682
    I use FI cleaner (usually Gumout's) about every 3000 miles on my cars (they are driven only 6000-9000 mi/year). I am happy with the engine performance and fuel economy of both my Elantras, so if it ain't broke, I won't fix it...
  • doohickiedoohickie Posts: 949
    So no CEL, huh? Even on the 04? I suspect what happened is this: I know there is adaptive technology in the Elantras. Perhaps early on I taught it some "bad habits" which gave me poor mileage; maybe by flooring it too much it made it run rich and the FI cleaner pushed just over the brink and the CEL came on. Upon a clean reset, and driving the car more conservatively, it seems to be getting much better mileage. By 300 miles I'm ready to fill up; this tank looks like it might go to 400 and this is in mixed driving. It would be sweet to be able to finally claim to break the 30 mpg mark. Just gotta take it easy for the rest of this tank... ;)

    Well, I did have two CELs on my '01 GLS, quite awhile ago. The first was traced to a gas cap that was not tightened enough (DW filled the tank for me, bless her heart). The second was due to a failed rear O2 sensor (replaced under warranty). No CELs on the 2-year-old '04 GT yet--no problems on that car whatsoever except a cloudy headlight cover (replaced under warranty) and a broken sun visor (replaced under warranty even though it had, uh, help getting broken). Oh, and I did the two recalls (gas line and OCS) but the OCS was working fine when I took it in and I don't know if they actually had to do anything on the gas line recall. I just bought some factory-matched spray paint and clearcoat for it, and I can't wait for some warmer weather so I can touch up a couple of scrapes on the front and rear bumpers and make it look like new again (well, after I have some small dings removed via PDR and do its spring cleanup it will look like new again).

    I have noticed that when my low fuel light comes on I have about 3 gallons left. But truth be told I think I see that light about once a year.

    The sign said "No shoes, no shirt, no service", it didn't say anything about no pants.

  • snakeweaselsnakeweasel a Certified Edmunds Poster.Posts: 11,685
    The fuel injector cleaner most likely had nothing to do with it. My guess is that it is just a coincidence of timing. Truth be told gas has cleaning agents in it that will keep the fuel system, including fuel injectors, clean. I have gone over 130k miles without using fuel injector cleaner and have had no issues. I personally am in the camp that fuel injector cleaners are little more than snake oil.

    Oh well, for $6-9 a year per car, at least the snake oil isn't putting a major crimp in my budget.

    The only thing I can reason on the CEL would be that the cleaner affected the O2 sensor (which is where the rich/lean condition is monitored)and once the concentration level was lessened by more fuel the condition went away. One of these days I will get bored enough to really look into how the O2 sensor works, but I suspect it is somehow temp related as there are codes that will set if the sensor doesn't come up to operating temp fast enough.

    I know lots of folks whine about the complexity of these control systems, but if you step back and look at the big picture they are really pretty cool. Imagine 30 years ago if you told someone you had a 2.0L engine that developed 130+ HP without a turbo/super, that would make 30+MPG at 70MPH in a five passenger car, have emissions so low you could run it in a closed garage (don't try this. even though the numbers support the non-lethal level of emissions, no reason to be stupid)and was durable enough to allow a 100K warranty.

    You would have been laughed out of the room.
  • backybacky Twin CitiesPosts: 18,682
    So you are saying that regular use of FI cleaner caused the O2 sensor to fail? The computer diagnostics reported a failure, and the sensor was replaced. This was after I had used the FI cleaner several times, and actually it didn't happen right after an application of the FI cleaner. And the 2nd O2 sensor has worked fine for about four years, while I have continued to use FI cleaner. I guess I don't see the relationship between the O2 sensor failure and the use of FI cleaner.
  • jlflemmonsjlflemmons Posts: 2,240
    No, not that it caused the failure, what I am thinking is that if the cleaner is overconcentrated (the old "If a pint is good, a quart should be better" mode)it may cause the sensor to read an over-rich condition. O2 sensors are actually very tough and a lot of the "failures" that get replaced are not failures at all, but the sensor seeing a problem that may be mis-diagnosed.

    Generally speaking, if a solid state electronics device is going to fail, barring outside event like lightening, they will fail pretty quick. The standard for televisions has been that if they work without problem for the first 100hours of operation, they will GENERALLY be good for about 10 years.
  • backybacky Twin CitiesPosts: 18,682
    I see. Well, I always follow the instructions on the bottle--one bottle per full tank--so I would be surprised if FI cleaner is the culprit in the failed O2 sensor. And it did happen fairly early in the car's life.

    that dealership is trying to rip you off...i would write to the hyundai regional office or the head office in california. i have a '01 gls with 80k and have done all scheduled maintenance work myself and the local dealership has never given me problems with warranty work. most of the early "scheduled check ups" consist of an oil and filter change with visual check this or that.

    An update on my own FI cleaner situation. To review, I used some cleaner at 7,500 miles and got the CEL (running rich). Whether they were related or not, who knows, but I reset the CEL by disconnecting the battery. That was a little over a week ago, and I got through the whole week without filling up (rare for me; I usually fill up every 5 days give or take). So I filled up this morning and got 27.9 mpg in mixed driving; by far the best I ever got in mixed driving ;) .

    Whether the CEL was due to the FI cleaner or just because the car was, in fact, running rich is hard to say. Whether the mpg improvement was cased by the FI cleaner or the CEL, who knows? But it got great mileage this tankful, hopeful a sign of things to come.

    On the other hand, 15 miles after filling up, I got another CEL (assuming it's the gas cap leak, even though I know for sure it was not loose. What a pain in the @$$. :mad: )

    My fog-free button on the main panel suddenly stopped working, so on the first revision I told the dealer that this had to be repaired. They did, but the button now doesnt make any noise like the other buttons. A/C, outside temperature, everything makes a sounding BLIP but this button. The cheek, the dealer says that no Elantra makes a BLIP noise on *that* especific button, the fog-free one. If you have a Elantra... a new one... can you please tell me if your car makes a BLIP noise if the button is pressed, so I can throw a lawyer to that looser? Thanks in advance.
  • doohickiedoohickie Posts: 949
    If that is on the automatic climate control, that is not available in the U.S., so I don't think we can help. None of the button blip on the manual system.
