Hyundai - Accent :: 2002 Auto Transmission - Downshifts With A Jerk / Thunk
2002 Hyundai Accent with automatic transmission. This problem happens only if I floor the gas gas on the highway (trying to pass somebody or get out of the way in a hurry) or if I apply too much gas after coasting around a sharp turn. My car will then downshift with a jerk and an audible THUNK!. Right now I just avoid those situations and it shifts through all its gears fine, it only happens when I cause a sudden downshift. Transmission fluid level and color fine.

Today my transmission suddenly disengaged while slowing down from 3rd to 2nd as if i switched to neutral.Car revved freely when i pressed accelerator. Then suddenly after a second it engaged again and shifted normally. Never had this issue before i racked up 1,29,000 KM on my ride.
I can't see it as "slipping" as there was no change in speed and it revved freely. Also I 'm due for fluid change. What can be the issue?
Sonata NF (2006-10) :: Auto Transmission - Spins And Make Whining Noise When Put In Reverse
I got a 2006 3.3l v6 sonata and for the past 6 month I have no had reverse which sucks let me tell you but I've looked into my codes it's throwing out. Anyway when I throw it in reverse it doesn't lock on it just spins making a kind of whining sound,
And when I'm driving it I take my foot off the gas or I slowly push the break it will jump down to third gear and get stuck I'll be doing 40mph at 4K RPMs, what this could be or what I should do?
Sonata I45 (YF - 2011+) :: Transmission Will Jerk / Buck Fairly Hard When Put Into Drive
I have a 2011 Hyundai Sonata limited with 68,000 miles on it. Once the car has been warmed up for awhile and I shift into drive after a stop, the transmission will jerk/buck fairly hard. It only does it while being put into drive and I haven't had any other issues while driving.

I drive a 06 Sonata 2.4L Automatic with 124,000 miles. I noticed that when I'm going about 45 or 50mph the car will slightly jerk continuously. It almost feels like its either hesitating to up shift or down shift.

The shifting in my Hyundai Sonata 2009 Limited V6 is horrible, having issues with shifting such as a hard jerk from 1st to 2nd when car changes gears driving. It feels like it is pulling back when the car changes into 3rd gear oh and you can forget trying to go uphill. It is completely horrendous it is shifting always up to 3000+ rpms struggling to make it uphill. Any way to achieve a smoother shift and also towards the uphill thing.

View 5 RepliesSonata NF (2006-10) :: Window Reverses Down Using Auto Up
2006 Sonata. I had to remount the drivers window glass which had slipped out of the clamps and fell inside the door.
Afterwards, if using the window auto-up feature, the window reaches the top and reverse back down to about the one-third closed point. Using the normal (non-auto up) it remains properly closed at the top.
My first thought was it needed to be reset by the well documented hold the switch up for at least .2 seconds method. I've done that and it hasn't solved the issue.
There doesn't appear to be any unusual resistance to movement which might activate any 'arm in the window' type safety feature. (if it even exists)
I would also expect that type of thing to work regardless if using auto-up or not anyways.
Sonata NF (2006-10) :: Auto Climate Control Not Working
I have a 2009 Hyundai Sonata that has the digital display for the climate control- which i am assuming is the auto climate control system that is talked about on here frequently. The problem is that the fuse for the climate control system continually blows, causing the display and all controls for the climate control system, to stop working. Put a new fuse it, blows again.

View 7 RepliesSonata NF (2006-10) :: 2009 Auto Throttle Hesitation From Standstill
My Sonata has developed a hesitation when accelerating from a standstill. Sometimes the symptom is worse. I haven't identified any correlation of this symptom with any other scenarios.
Symptom : When at a stand-still, lightly pressing on the gas pedal doesn't result in corresponding slow acceleration, it is only after a certain threshold (of throttle application) has passed that power from the engine is transmitted to the wheels. When this occurs, the result is a jerky start.
In other words, trying to feather the gas pedal to allow a gradual and smooth acceleration from stand-still is not possible when this issue occurs.
I believe the 09' Sonata has a drive by wire throttle correct? If so, could this be a computer calibration issue?

View 2 RepliesCorolla / Matrix 2009-13 :: 2010 S - Auto Trans Downshift Delay And Jerk
I have a 2010 S with an auto trans and 68,000 miles. I've never replaced the fluid or filter. Over the last 10,000 miles or so, I've noticed the following in regards to shifting.
I will being on a merge ramp to the highway rolling along and waiting to pull out into the flow of traffic. I'll be traveling along at a constant speed, say 30 mph, with constant pressure on the throttle waiting for my opening in traffic. I will see my opening and floor it. That's when (sometimes) the car seems to get very confused. It doesn't shift back right away, it lingers in 3rd (or OD) and picks up a tiny bit of speed. Then, it hesitates with no acceleration, and then roughly shifts to 2nd or 1st. It feels more like it forces itself into gear and, once in gear, it accelerates like it should.
The biggest issue for me is that this whole process takes about 3 or 4 seconds. That's not very long, but when you're trying to merge onto the highway or cut into traffic, 3 seconds is the difference between being safe and a close call.
Transmission fluid appears to be full, is a nice red color, and doesn't smell burnt.
Sonata NF (2006-10) :: 2008 GLS Auto - Slight Tick If Stand In Front Of Car Idling
2008 2.4 GLS auto, 64000 miles
Only taken this car on 2 highway road trips. 2 years ago = 34mpg on 900 mile trip (@36000 miles), last week = 31 mpg, EXACT same trip, this time in December, last time in September. Other difference - slightly perceptible tick noticeable if I stand in front of car idling.
Bought July 2009 (almost 24 months old) @ 32000 miles, oil changes every 3000 miles since, tranny fluid at 60000.
Elantra HD (2006-10) :: Auto Transmission In Default Mode / Stuck In 3rd Gear
My auto transmission in my 2007 Elantra with 125,000 miles went into default mode, stuck in 3rd gear. No codes went off. I drove it home this way, but after sitting for 90 minutes, now it works fine. I've heard about the input and output sensors. What should I replace? I went to HMA service to get info on both sensors, but it wasn't detailed enough.
View 3 RepliesAccent MC (2006-11) :: Auto Transmission Not Engaging At Idle Then Abruptly Chunking Into Gear
My wife has been using her mom's 07 Accent, the mom is 90 and hasn't been incapable of using it for a while now. I did an oil change (without paying much attention) I've never seen this type of car before. Oddly the oil level seemed outrageously over full and still dirty
Then upon driving it the automatic transmission was all wacky, not engaging at idle, then it abruptly chunking into gear...
So I check the transmission fluid level and it's not on the stick. Research here let me know SP-III is what I'd need. Then while surfing a youtube vid regarding this model's transmission it hit me in the face, I'd drained the automatic transmission fluid! Went to the Kia dealer got 3 quarts dumped it in there, drained the overfilled 5.5 quarts of old and new oil rectifying my mistake, which brings me to the reason for this post.
This 2007 car only has 24,300 miles on it and I mistook the automatic transmission fluid for outrageously dirty engine oil! I swear this stuff looks like it's fulla carbon black n burnt up. My question: is it normal for the trans-fluid to have such a degraded appearance in only 25,000 miles?
Ford F-150 - 1997-2003 :: 2002 - Auto Lamp Not Working / Lights Blinking - Relay?
I have a 2002 F150 FX4 Lariat, and last week while driving at night with the light switch turned to auto lamp the lights suddenly started turning on and off rapidly and there was a clicking noise, which I assume was a relay cutting out. I turned the headlamp switch to the on position and the lights stayed on. When I got home the lights would not turn off, and when I turned it to autolamp the blinking started again, but in any other position the lights stayed on. I had to unhook the battery. I then purchased a new headlamp switch and my ford mechanic buddy installed it, but now the autolamp feature will not work. Is there a relay that may have got cooked?
View 1 RepliesSonata I45 (YF - 2011+) :: When Try To Shift To Any Gear Car Would Jerk Violently
Lately when I turn on my car and shift the gear into reverse, the light that identifies which gear it is on doesn't come on. Just white light. When I try to reverse it wouldn't. When I try to shift to any gear it would jerk violently. Only thing I could do is put it back to park, shut down the car and restart the car back up. Then it acts normal again. Taking the car back to the dealership for recall but also mentioning this issue I am having.
