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.
View 7 RepliesSo my car has recently begun having an issue shifting hard into drive after it warms up. It doesnt shift weird in any other gear or while driving. I had the trans temp sensor replaced last year under the tsb due to it shifting weird in all gears and a CEL. I was thinking either the fluid level or another bad sensor.
View 2 RepliesMy 2013 Sonata 2.4L 4cyl is very hard to drive when it's slippery out (snow, ice).
The throttle is so touchy, it just wants to spin as soon as you touch the gas pedal. It's manageable on dry pavement. It has always been like this since new, but this winter there's been so much snow I'm getting a little annoyed by it. Even with traction control I have a hard time making headway from a dead start.
Tires should be OK - only have 12,000 miles on them.
Is there a cure for this issue? Re-mapping EFI??
The other day I noticed the car slipped into reverse fairly hard, then when I placed it into drive it also slipped in fairly hard. Once I was out on the road it hesitated and then slipped into gear 3rd then 4th, and when I slowed down it seem to hesitate when gearing down. Two days passed and no problems, then today started up again, and now the "check engine" light came on...! Shifted ok on the way home this evening but check engine light still on. Only 34K, 2012 bought in June 2011. Has been an absolutely brilliant ride up until this week. I understand the tranny is sealed ? Any tips besides taking it to a dealer ? Problem is I live quite a ways from one, and finding the time.

When driving at 65 mph only while accelerating there is a jerk/buck almost like it tries to go faster but it gets stopped violently. I Checked spark plugs, wires, etc. The plugs were twice the gap so I just replaced them with wires and coil pack since they were original.
Still have the problem...and now I am testing several things. Tps seems OK. Voltage does not jump but it doesn't go higher than 4 volts even if its rated for almost five. I checked on a cheap scan tool voltage for o2 sensors. Both upstream seem to be normal. Down stream seem low and a bit jumpier than I would expect. And I am hoping its not the cat.
I have a very well maintained 1998 Ford Explorer 4.0 SOHC 4X4 with only 67,000 miles. Sometimes at highway speeds ( 65MPH ) there is a fairly pronounced bump / jerk. I will also happen occasionally when accelerating from a stop. IMHO, it's not a slip. Fluid has been flushed and is bright red. The best I can tell the RPMs are not jumping when this happens. I've all but counted out an engine misfire. There are no engine or OD light on. Where I should begin troubleshooting? I don't want to spend tons of money trying to isolate the issue but this Explorer is in exceptional condition so I want to have it fixed.
View 8 RepliesThe 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 4 RepliesI have a new issue that started last Friday. When I put the truck in gear and let it begin to pull itself, drive or reverse, it has a strange jerking or slipping deal. It doesn't happen every time but when it does you can feel it in the drivetrain. I took it to the shop that did the motor work and they ran a diagnosis(while I watched) on the motor and its turns up nothing. It runs perfect, shifts like it always has, but just has this jerking/slipping thing when I let off the brake and it starts to pull itself.
If I go from brake to throttle its fine. I had the rearend diff worked on to fix the leaky ring and pinion seal and the differential cover sealed at the dealer last month. I searched and don't see anything like what I am experiencing. Could my tranny be giving it up now? It has never been overworked and never overheated. I had the full fluid service done at about 70k and now it has about 130k on it.
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.
View 2 RepliesToday while backing into a spot at work (parked on a flat surface) my 2011 Sonata GLS automatic tranny, when I went to shift the car in reverse felt a big jerk and rather loud noise from shifting.... Haven't heard it since.... I think this happened to me once before many months ago... also on a side note why do I hear a almost a crunching noise when I am steering the car in reverse... I just had my car in for a oil change too.. I'm the only driver and owner of the car it has about 42k on the odometer.
View 17 RepliesNew here. I have a 2001 F150 which i love but lately has been an issue. I started it up a few weeks ago after it set over night. i threw it in to reverse and notice it hesitating while reversing and it has small trouble accelerating but does buck and jerk while trying to maintain speed. So I took it to my well trusted mechanic and he ran compression test and ran the highly prolific OTC scanner on it and nothing. I have changed my mass flow sensor and I dont show any misfires or any codes pending. I did replace a busted catalytic convertor a couple months back. Im running out of places to turn.
View 6 RepliesRecently my 2006 2.4 L encounter auto transmission jerk intermittently with P0734 and P0765(bad D shifting solenoid. Change the bad solenoid and the problems still occur. Later check all the wiring as per hyundai TSB and all seems to be ok. Then an error code appear that indicate bad ATM relay (auto transmission module). I interchange the suspected relay with the horn relays and the problems resolved. I did check the relay coil which is ok but the mechanical contacts is badly corroded that results in some resistance that causes the 12v supply to the Solenoids to be affected. (the relay is situated in the relay compartment next to battery).
View 6 RepliesI have a 04 grand caravan 3.8 liter. after filling up with gas & only after filling up i have a prob with the way the van runs. it will start and idle fine but once i shift in to gear and try to drive it starts to buck. if i take my foot off the gas it wants to stall. if i shift in to N or park the RPMs are around 400/500. if i rev the motor in N or park it will smooth out and idle fine and drive fine until the next fill up, then it starts all over again.
View 1 RepliesI have a 2011 corolla S. sometimes when i shift from park to drive, it shifts smoothly and easily. most of the time when I am shifting from park to drive, it isn't smooth and doesn't shift easy. You can hear when you move it from park.
View 3 Replies2011 Sonata will not go into drive after washing under the hood. It will go into reverse, Park and Neutral, but no drive. Also, the gear indicator light on the dash is black when you try and put it in drive. What I may have gotten wet that could have caused this?
View 1 RepliesMy battery is dead, but I need to drive for 5 hours. Can I boost it and drive for 5 hours on the highway? Would this damage my car? I can replace the battery when I get home.
View 4 RepliesI bought a new 2012 Sonata GS about a year ago. I have recently realized that the car should have the ability to play music from a usb stick. I would much prefer this to playing music through the phone as that eats up the battery and takes up a lot of room. Anyway I tried just dragging mp3 files into different artist folders on an empty usb drive and then plugging it into my car. Unfortunately the car was unable to read the music. are there any special formatting/ other things I should do to either the stick or the music that would allow the car to play the songs from the usb drive?
View 4 RepliesSo a noise has come up in my Sonata. Sounds like it's behind the dash. Only happens when the car is idling in drive and the AC is on. With the slightest increase in rpm, it goes away. Doesn't happen in N or P. Sometimes goes away, but also sometimes gets louder than what I recorded below. I've only checked the dash and glove box so far. [URL] ......
View 5 RepliesAbout two months ago, my EPC light came on and my check engine light started flashing while I was driving home from work. Never heard of/saw that EPC light before. The car started to stutter and buck really bad when trying to accelerate (on light and hard acceleration). Also, when sitting idle (like at a red light or stop sign) the car would still buck but not as bad as when driving. The only time the car doesn't buck is when I am cruising, like after I just get done pressing on the gas and the car is coasting basically. I call the mechanic the next day and he tells me right off the bat, it sounds like a Crankshaft Position Sensor and to drop it off so he can look at it. So I drop it off, he tells me he believes it is just a bad coil on cylinder 1, so he swapped it out and gave me an oil change (it was due for one). Picked my car up on a Wednesday, it seemed fine. Then on a Saturday same issues and same warning lights came back on. So I had it scanned at Autozone, misfire on cylinder 1 and 3, random cylinder misfire and multiple cylinder misfire, so I call him and tell him, he said just bring it back he'll swap it out. I changed the coils myself since it only takes 10 mins. The car seemed fine for about a month. Then two weeks ago, all of the same issues are back and same warning lights.
Had issues with the EPC light? Also, is any truth that the Crankshaft Position Sensor can be related to this or was the mechanic completely wrong? Read another post by someone else and there was talk of carbon buildup. My friend is mechanic and said that he thinks it might be a fuel related issue or electrical, since the issues keep coming back. Also, it misfires more when the heat is on and seems like the interior lights flicker a little when it's misfiring at idle, it's very subtle, definitely notice it so I don't know if it's electrical, fuel related, carbon build up or what.
-February of 2014, I had a fuel pump replaced by the dealer (it was for a recall)
-Back in January 2015, I had the ignition coils and spark plugs replaced by a friend (who is a mechanic).
-In July I had the lifters replaced (by the same mechanic I called)
-Been up to date with oil changes
-Use plus gas from Citgo
Going to drop it off at the dealership tomorrow.
I have a 2001 hyundai accent GL the transmission has started shifting hard when it shifts into drive. It shifts fine and smooth from first to second but when it shifts into drive it hits drive hard and sometimes it acts like it doesn't want to shift and if you let up on the gas it will go ahead and shift, but when it shifts to overdrive it seems fine but hits hard when it down shifts back to drive. Also I have noticed a couple times when it goes to shift into drive the engine seems like it revs up some but when you let off the gas it goes ahead and shifts.
View 3 RepliesI have 2011 Sonata with just over 3500 miles on it. About three weeks ago I was driving down the road going about 45 mph when my sonata jerked like I had hit a pothole. I pulled over and checked it out and saw that I had not hit anything. When I put the car in reverse it jerked, and when I put it in drive the car bucked badly. After that, it had almost no acceleration as if it didn't want to get out of first or second gear. I took it to the dealership and they were able to recreate the problem and called it an "Intermittent Hard Shifting Transmission."
They told me they had to replace the transmission, which they did. After they replaced it they said the car was still hard shifting. So they replaced the transmission again, and again the problem persisted. Yesterday they told me they were ordering a brand new transmission, blaming the problem on the fact that the previous transmissions were re-manufactured.
I'm waiting to hear back after they install this "new" transmission. Maybe the third time's the charm, but this seems ridiculous.
