Hyunda Azera Transmission Questions

Our '07 Azera accelerator has a problem when pushed to W.O.T. (wide open throttle), it stays there! (Almost brings on screaming flashbacks of 60s-70s-80s Chevy V8s with broken motor mounts!) It's happened to me a dozen times or more, mostly when trying to pass, or merge safely into a fast-moving flow of freeway traffic. Only occasionally does it NOT stick.

It was checked by the dealer who "lubed the cable", which seemed to handle it, but only for a couple of days. Then it was back to its old tricks.

When the frequently-noted "hesitation" is combined with the sticking accelerator, the vehicle is a real handful. I've instructed my wife re. how to deal with it should it occur, but I sure hope it doesn't. Just the hesitation is very dangerous, but in combination with a delayed but stuck W.O.T. the threat of the potential damages are all too real.

When the Azera visits the dealer again this week (dealer also denies it has suspension 'clunking, hesitation, or rough idle!), I'll definitely take a service writer and/or tech for a test ride to eliminate their perceptual difficulties.

Any other Azera owners experienced the sticking accelerator syndrome?

    If my car experienced that type of problem I would immediately contact the dealer and Hyundai and not drive it until I was assured that the problem had been corrected.

    Is the Azera accelerator "drive by wire?" (electronic) and not a cable setup??
  • I'd be willing to bet this IS NOT a transmission problem! So why is it titled as such, and not listed as "accelerator pedal sticking"???

  • The Azera throttle control is a drive-by-wire setup. This means that the throttle is controlled by a servo that is driven by the computer. I do not know if there is a cable between the control servo and the throttle itself. In any case, the problem can be a sticking throttle butterfly (most likely), a sticking rheostat connected to the gas pedal (next most likely), a faulty servo (less likely), or a computer fault (not likely).
  • I have a 2009 Azera that has had a noticeable shudder between 40-50 MPH since I got it. It now has 1,500 miles. The dealer tells me it is "torque converter clutch lockup" and it is normal. They say Hyundai has not adressed the problem in the ECM that controls it. I have been driving for more than 50 years and I think they are nuts. No other car handles like that, not even their Sonata or Genesis. They have already replaced the tires and re-alligned all the wheels. Any ideas? I am meeting with their District Parts and and Service Manager in 3 weeks.

    I bought a used 2008 Azera with 7900 miles on it. When accelerating from a stop between 10-20 mph there is a noticeble shudder that dissappears after 20 mph and is not resent 0-10mph. When driving at higher speeds on the highway there is a minor vibration but nothing serious. Anybody got any ideas what it might be?

    Ask your Hyundai dealer to do the Wide Open Throttle TSB. It is a software flash to the ECU.

    Also, ask him to reset the computer so that it learns & adjusts to your typical driving style. Azera's transmission 'learns' and adapts the the transmission to driver's style & stores the information. Maybe the previous owner was heavy-footed.

    Thanks---I hope that's all it is.

    I had the technician look it over and he found a broken motor mount which was replaced. It seemed to help but there is still the same shudder between 10-20mph in 2nd gear. He said there was a TSB on the car that he took care of but it wasn't related to the transmission. Do they not want to do the work because I didn't buy the car there? Is there some reason that he doesn't want to do the flash? Is it a big job? I don't know, I'm confused as to why it hasn't been addressed. Anyone got any ideas?

    It shouldn't matter which Hyundai dealer you take the car to, they must all honor the warranty. I currently do not take my Azera to the dealer where I bought from simply because it's inconvenient for me. Flashing the transmission is hardly a big job...it simply takes connecting the computer to the car and running the program. I've had my tranny flashed a few times, it only takes a few minutes. Why the mechanic wouldn't want to do it is beyond me...unless he's not a certified mechanic and doesn't know how to do that type of thing. :confuse:

    You can always do as we are doing. File under your states Lemon Law. :lemon:

    Find out the law in your state and follow the guidelines, and either Hyundai fixes it or is forced into buying it back.

    Good luck.

    My understanding of the Lemon Law was that the same repair had to be done 3 times unsuccessfully.

    Another path to take my be the Better Business Bureau.

    Lemon laws vary from state to state, so one always needs to find out what the requirements are in one's own state. Just fyi. :)

    Understood. :D

    The car has no power when it does this. Is this normal?I don't recall it doing this before.I am forced to use the tip tronic to get a lower gear. Since it does not display the gear it is in, I have no way of knowing what gear it it in but I suspect 4th if the rpms are that low. Can this be adjusted? Car has 25k on it.

    I have an '06 Azera. The torque converter will lock up with the car in 5th gear at around 40 MPH. At that point the RPMs are around 1200. Gentle rises and/or small tip ins of the throttle will cause the torq converter to unlock and the RPMs to rise to 1500 or so ( while still at 40 MPH ).
    I drive the car pretty gently, therefore the adaptive transmission in my car has learned to hold higher gears in the interest of economy. However, if I go to anything over half throttle under the abovementioned conditions, the car will unlock the converter and drop to 4th gear. It is difficult to get a downshift to an even lower gear without flooring it though, and there's quite a delay in that, too. That does become a problem when I need lots of acceleration, such as when merging unto a freeway after traversing a ramp at around 35-40MPH. On one ramp in particular, where at certain times of the day I anticipate heavy freeway traffic, I have to use the tiptronic and manually select 2nd or 3rd - it's just the nature of the beast.
    Other posters have suggested a reflash of the transmission, but my feeling is that it will soon adapt and operate exactly the same as before. IMO, if you purchased your car used then a reflash may be in order so that it can adapt to your particular driving. Otherwise, do what you're doing and try to anticipate a situation where the car needs to be in a lower gear and use the tiptronic.
  • I have an 08 Azera.
    Can someone tell me when (mileage) the transmission fluid needs to be changed?
    The owner's manual seems to be confusing about this.

    Thanks,
    Jerry
  • 30k to keep your 100k mile warranty intact

    no way.....my '06 warranty says 105k miles...30k miles is for severe conditions
  • allmet33allmet33 Posts: 3,557
    Never heard of tranny fluid that would be good for 100k miles. I've had my transmission serviced and the service manager told me that 60k miles is the usual. Speaking of which...gotta get mine in for service!
