#2 of 3028 '00 GLS problems by astrol Aug 27, 2001 (7:59 am)
Only one issue to report so far in 24K miles. My front brake rotors and pads had to be replaced due to warpage. This was not done as a warranty item which I am currently challenging with Hyundai. I have received assistance in this from the Hyundai Advocate over at T.H.C.org. and will report any news here in the future.   There is still a slight buzziness to my rear door panels near the armrests when traveling over choppy road surface. I have made many attempts to insulate the door components and have finally reached a compromise level of sound. I may simply apply Dyna-Mat as the source seems to be something which I cannot permanently affect. Perhaps the window regulator design?

#3 of 3028 Is this Transmission Problem Normal? by wiggler Aug 27, 2001 (6:24 pm)
I have a 2001 GLS V6 and the Auto Trans seems to shift with a stutter from 2'nd to 3'rd... but only until it seems that it warms up (about 4-5 miles of driving). Note that the Temp gage shows normal temp after about the first mile, but it seems the trans oil needs to warm up and it must take the 4-5 miles. After that, the trans shifts smoothly. Have noticed also on the stutter of the shift that the tach jumps from 2500 to 3000 rpm's when it does this. Again, only on the 2nd to 3rd shift, WHEN COLD. All other upshifts seem to be fine, cold or not. Currently I have about 1700 miles on it, and it has done this since new. Do I need to be concerned, or do they all act like this. Thanks for any feedback.
#4 of 3028 Tranny by jc58 Aug 28, 2001 (3:38 am)
I too have noticed the tranny shift as you have described, the rpm's seem to jump and it sort of hesitates before shifting. It does only seem to be on the 2nd to 3rd sfift. And as you describe, it goes away after a while and shifts smoothly.   Other than that no problems. I don't put too many miles on it ( I have had it since the end of May and have 2000 miles on it, but so far so good. I have a 01 GLS with moonroof, auto. The only other small item I have is a buszzing over rough surfaces, which seems to be from the passenger seat or the console. It is not too loud yet, so have not been able to isolate it.   Seem to average about 23 mpg in my commuter driving, which is ok, especially since I have noticed gas prices for regular have gone over $1.90 again in the town I live ( 40 miles west of Chicago).
#5 of 3028 Same Tranny Shift in my Base Sonata by netzen7 Aug 31, 2001 (4:26 pm)
My '01 Sonata also shifts "odd" at times, like described above. Seems to smooth out and then return unexpectedly. Warming up doesn't help me, happens between 2nd and third in the same RPM range. Worse when the A/C is on. I checked at the dealership, and there is a service bulletin out for some 2.4L automatics (like mine), but not mine specifically. Guess the VIN tells all. They "reset adaptive" and off I went. I'll ask them again when in for my next oil change. The trouble is the issue really is subtle, random and therefore "normal"??? No diagnostic codes print when they checked it out. I wouldn't complain (My Honda actually shifted worse) except the ride is so darn smooth, this little hickup just annoys me when it happens. I'm a computer programmer, so my speculation this is a "bug" in the Electronic Transmission code . . .Like I know anything about it - NOT. Still, something isn't quite right. I've only got 3000 miles on the car, so maybe the thing just hasn't loosened up yet? Replies to this message: ane (Jul 28, 2007 5:48 pm)
#6 of 3028 Floor mats by dougndo Sep 24, 2001 (3:59 pm)
This seems small, but since nothing else is troubling me at all, I'll post it here. I'm having a problem with the driver's side floor mat anchor. It keeps snapping open, then the mat gradually creeps up as I drive.   This began after I had the audio system replaced, and I think the stereo shop guys messed it up when they were crawling around.   Does anyone else have this problem? How did you fix it? I'm not inclined to leave my car for a day at the dealer to get this fixed. The anchor looks like about 75 cents worth of plastic, so it probably costs $9.95.
#7 of 3028 Floor mat anchor solution... by 2000glsv6 Sep 25, 2001 (2:28 am)
I had the same problem as you are having. I used some 5 min epoxy I found at the local auto parts store and used that to keep the anchor together. On mine, because it had been coming undone for so long, the carpet started to become very weak in that area. So I also drilled a small hole through the clip and the floor and installed a self-tapping screw to hold it all together and tight. It does not move any more now. For you, the epoxy may be just what you need. Try that first. If not, then go for the screw repair.
#8 of 3028 Floor mat prob by sonatava Sep 25, 2001 (3:57 pm)
I haven't had that problem, but then again, I went to Walmart and bought 2 of those thick rubber all-season mats for the front. They're about $7 a piece and work really nice for when it's raining. The brown matches the Sonata's tan interior to look good enough for me.
#9 of 3028 floor mat prob... by 2000glsv6 Sep 26, 2001 (6:03 am)
The mat problem described above is for the factory mats that use the anchor to keep them in place. I don't think aftermarket mats have this problem with the anchors.
#10 of 3028 Shift / rpm trouble by sonatabean Oct 01, 2001 (4:40 am)
I have two 2000 GLS V-6 with auto, and one of the cars had the same shift/rpm/"jerkiness" problem y'all described. It got severe enough, however, that the problem went beyond hesitation and weird shifting.   In my case, the car started to misfire and stall.   The problem, according to my dealer, lies in a engine sensor giving feedback for the electronic ignition spark. Somewhere between an upshift or downshift and the subsequent change in RPM and required adjustment in ignition spark, something goes awry and the problem you have happens.   The sensor that initiates the spark needed to be changed in my car. Once that happened, the car ran absolutely perfectly.   Oh - and the comment about Honda's shifting harder? No kidding! I still can't understand the rave about Honda. We've had two in the immediate family and one was complete garbage (transmission failure, 30K; Valve/seal/gasket failure 60K; required a new engine and carb at 90 K) and the other is simply average.   So far, the Sonata has been a much better car, despite the sensor getting jiggy.   Have you dealer check out that ignition sensor thing and see if it solves the problem.

#11 of 3028 Shift RPM problem by rhard49 Oct 04, 2001 (10:34 pm)
I have to say this they're consistant. My 2002 LX has the same 2-3 shift slippage when cold the tach jumps about 500-1000 rpms and the shift happens and it goes away when hot. I just took it back and was told it was normal! So we walked around to the front and took a brand new one cold out for a drive, Hmmm not normal on that one. Three weeks old and waiting for a meeting with the regional guy. It is tempting to hit it cold on that 2-3 shift and let the clutchs chew it up, It may be easier then fighting with them. And god I wish they'd train there people on what the heck and adaptive transmission is and explain what a microcontroller is. I heard way to many problems being blamed on adaptive during my recent visit.
