#1 of 17 accelerator pedal sticking (OPEN!) by purplish Sep 23, 2007 (5:01 pm)
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?   J.R.

Replying to: purplish (Sep 23, 2007 5:01 pm) 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"???   J.R. SoCal

Replying to: purplish (Sep 23, 2007 5:01 pm) 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).
#6 of 17 2009 Azera Tourque converter clutch shudder by nrosenthal Jun 08, 2009 (2:08 pm)
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.
#7 of 17 2008 Azera shudder by brf8845 Jun 18, 2009 (5:22 am)
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?

Replying to: brf8845 (Jun 18, 2009 5:22 am) 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.

#10 of 17 Shudder Still There by brf8845 Jul 06, 2009 (7:31 am)
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?
