Sonata NF (2006-10) :: Harsh Downshifting When Coming To A Stop
i drained the 30000 mile fluid two weeks ago because it was harsh downshifting when coming to a stop... I was curious if others noticed a lot of metal sludge sticking to the magnetized drain plug???..

2009 Hyundai Sonata automatic: When downshifting from 4th to 3rd it feels like I hit a bump, or like I just hit the brakes hard for a second.
What could it be? It's most noticeable when the car is cold. I have 82k miles on it, so it's still in the "power train warranty".
Sonata NF (2006-10) :: Transmission Jerks When Downshifting (intermittent)
My daughter has a 2010 Sonata with a 4 cylinder and an automatic transmission. She is pretty frustrated with an intermittent problem. Every once in awhile, especially if the engine is cold, the car jerks while slowing down. She believes it is the transmission when it down shifts. I have driven the car and have not been able to duplicate the problem myself. The dealer recently changed the mapping for the transmission in hopes that would work but it hasn't. The dealer hasn't been able to duplicate the condition either.

View 7 RepliesSonata I45 (YF - 2011+) :: Downshifting From 4th To 3rd Right Around 35 Mph
Just picked up a 2012 GLS two weeks ago. So far I like the car. Unfortunately, I do about 40 miles a day of traffic driving. I have noticed the car seems to downshift from possibly 4th to 3rd right around 35mph. This downshift is noticeable and the engine has to rev to match the change. It is not a high rev, just a noticeable engine braking. Is this normal? I dont feel like anything is wrong just seems like the computers are not sure when to downshift.
When the car comes to a complete stop with your foot on the brake, does the car lower its rpm by 100-200pms? Seems like this is a gas saving technique. I have noticed it when While at a light and I lift my foot slighty the car feels like either the brakes are grabbing or the rpms are to low.
Sonata I45 (YF - 2011+) :: Downshifting On Uphill
I travel this interstate route often that is somewhat hilly. I always use cruise control. When I got my 2007 Sonata (I4) 4 speed A/T and traveled on this road I never noticed much down shifting. Later my daughter bought a 2010 Sonata (I4) 5 speed A/T, and on this road I noticed the Xmission downshifting sometimes. When I got my 2013 (I4) 6 speed A/T, I started noticing it more often downshifting. I'm sure thats since the final drive ratio is much higher in each successive car. When my wife is driving she doesn't notice but I can tell even from the passenger seat. I can stop the downshifting by putting it in manual mode. but I see the RPMs increase somewhat. I assume thats from the TC lockup disengaging and the CC trying to maintain speed if a long hill. I suppose if the hill was long enough and steep enough that I would eventually lose speed but that doesn't occur(very much). If that is more economically that letting it just go ahead and downshift. Am I the only one annoyed by this constant up/down shifting?

I've been driving my wife's sonata to work this week and notice as I start to slow down at around 20MPH the car almost surges a little bit. Maybe I am not diagnosing it correctly but it's almost like it's downshifting rough.

Upshifting is fine, downshifting gives me a big thud. Bigger from 3rd-2nd smaller 2nd-1st (I think).

View 6 RepliesElantra HD (2006-10) :: 2008 - Downshifting Occasionally At Highway Speeds
Have a 2008 Elantra GLS with 63K miles. A/T was serviced by dealer at 51K. Car now occasionally downshifts from 4th to 3rd when driving between 60 and 70 mph. Happens only when trans is hot (after 2-3 hours on hiway). When it occurs, it searches for the right gear, going back and forth from 3rd to 4th for several minutes before returning to normal. One thing odd is if I shut the car off for 5 minutes after it occurs, it runs fine afterwards. Do I need an ECU update or do I have a A/T problem?
View 11 RepliesSonata NF (2006-10) :: 2006 (2.4l Engine) Stalls On Red Light
2006 sonata gl with 4-cyl engine. Car runs/feels fine. Installed HID kit a while ago (with harness) and no problem. Driving home late afternoon (with AC on hi) stopped on red light. Radio was on but NO HID lights on - then momentarily car stalls. Starts back up right a way and NO check engine light. Tried AC- works fine, turn the lights on (HID 35w slim balast), radio on - everything is fine.
My "suspect" is old battery (original!) and I think that for a short moment charging system (alternator) could not keep up/charge battery while car was idling with AC and radio on (hi load).
How long is original battery good for (5-6-...yrs)? Looked earlier at Everstart batteries (or was it Eveready brand?) made by Johnson. I could only find a few batteries but they were sitting on the shelf since last summer (sticker said made 07/2010 !). Are they any good?
Sonata NF (2006-10) :: 2006, Stalls After Starting
Usually in the morning after starting the car, when I put the car into reverse the car stalls. I start it up again and it works fine. It has been doing this for a few months. When I went to get oil change they said I needed to replace battery so I did. Problem is still there. It has done this twice when I try to take off from a red light. I have no check engine lights either. My car has 105,000 miles but cannot really afford to buy a new car at the moment.

I've been noticing this noise recently and I'm wondering if it's normal with the DSG. Almost a clicking that I can hear, mostly when downshifting through 1, 2 and 3. Not sure if I simply can't hear it above this due to road noise though. Threw the GoPro on a suction mount and got a bunch of clips from a short drive around the neighborhood.

When approaching a red light, if I take my foot off the gas to coast, it feels as if the transmission 'downshifts' at around 30mph. I can't actually feel the transmission shifting but there is a definite slowdown in speed, not just a gradual slowdown. Is this normal? I ask as doing the same in the '04 RX it does not do this.
View 5 RepliesGolf IV R32 :: Stuck In 3rd Gear - No Downshifting?
Yesterday I took the R out to grab some food on my lunch break. Didn't drive like a lunatic or anything, pulled into T-Bell parking lot and the car didn't want to downshift. Ok Weird. coasted in, parked, and put it in neutral and let out the clutch and the car stalled like it was still in gear. Go to leave and the car doesn't want to go into reverse. Thats when I realized something had gone seriously wrong.
Basically the car is stuck in 3rd gear. I can get the shifter to engage into reverse but the car tries to creep forward like I have the e-brake on. It doesn't go into any other gear but 3rd or 4th, but even when the shifter is in the 4th position its still in 3rd gear. Even when the shifter is in the neutral position its in 3rd gear. I limped the car home. I've looked into it a little bit and I'm leaning toward the 3/4 shift fork being broken. I know this won't be a cheap repair.
I think if it is the shift fork I will be upgrading the the one piece steel versions.
Touareg :: Bang When Downshifting From 5th To 4th Gear
I have been having this problem for the better part of a year, about 80% of the time when my transmission tries to downshift from 5th to 4th gear I hear a loud thud/bang which shakes the vehicle. The other 20% of the time the donwshift is smooth. I have tried manually shifting and get the same result. The problem does not seem to be getting worse. I have adjusted my driving and when accelerating in 5th gear at moderate speeds I accelerate just enough to keep tranny in 5th, so I don't get the thud.
View 4 RepliesGolf V R32 :: Braking Malfunction When Downshifting
When I downshift while braking, especially in the lower gears, it feels like the brake pedal depresses further. And why does this happen?
Also, do people find you get cleaner downshifts if you have the gas pressed down a little, or do you downshift while braking, or just downshift without either?
