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.

Tonight while driving and accelerating fairly hard we began to hear a noise. The car sat parked for roughly 5 hours and then we began to drive it home (apx. 12-15 miles). About halfway through the drive the power steering went out and the battery light came on. The battery light would turn off and the drivers seatbelt light would come on even while it was buckled. These two lights alternated being on and off 2 times each. We heard something that sounded like a rock got kicked up into a wheel well. After getting the car home with no power steering we noticed the car had begun to run very hot. almost all the way up the gauge.

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.
View 4 RepliesSonata NF (2006-10) :: Auto Transmission Jerk Due To Bad Relay
Recently 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).

My sonata 2012 with 71K km on it just started hard shifting in the morning, after first start. It slamming in D from R very harsh and then shifts all other gears for ~3 minutes harshly (upshift / downshift) and then it gets fine and shifts gears with absolutely no problem throughout the day. Dealer of course was not able to reproduce the problem.
View 37 RepliesHyundai - Sonata :: Hesitates And Sputters, Mostly In Lower Gears When Not Accelerating Hard
I recently bought a 2004 Hyundai Sonata 4cyl with about 65k miles. In the past few months I've noticed that it likes to sputter and hesitate at times, mostly in lower gears when I'm not accelerating hard. At highway speeds it's mostly fine. It's also fairly random - some days it's really bad and others it's fine. Also seems worse when in reverse. I don't think the plugs have been changed so that's one idea, but I'm wondering if it's a bad fuel filter, exhaust manifold leak or something else. It's not throwing any codes (and yes the light works) and it has never stalled completely out.

I have a 2006 Chevy 2500HD with about 180000 miles. All of a sudden the transmission is shifting extremely hard at times. It doesn't shift this way all the time. What could be causing this problem? It doesn't have to be under hard acceleration either when it does shift hard. It sometimes is during hard accelerating and sometimes it is under very little acceleration, but as I said it doesn't do it every time. When it does shift hard, it seems to do it in all gears.

My 2011 Sonata SE gets a rough idle when my AC is turned on, and sometimes it produces a whirring noise as I'm driving in low gears. It all goes completely away if I turn my AC off. I'm afraid my AC might go out at an inopportune time. What could it be?

So my 1998 Toyota Corrolla jumps and jerks after I switch gears. It only does it sometimes and I have seemed to narrow down that it does it mostly when the air conditioning is on and between 3rd and 4th gear if I don't have the RPMs just right. There is no smell nor any mettalic grinding. I'm thinking it's something to do with the transmission.

I have a Sonata 08. I have recently installed a 740W amp and HID lights. During the Winter everything worked fine with just the amp. I then decided to install HIDs. I have a relay and a capacitor on them. but I have a weird power problem. Sometimes when I have my AC running the engine shuts off when I turn on my lights. It feels like a surge. I have to restart the car. Also while the AC runs the car feels a little shaky like it is switching gears while parked. What's going on?
View 25 RepliesCelica :: 2000 GTS Automatic Transmission - Slight Jerk On Shifting Gears
I bought the car about a week ago, whenever the auto tranny shifts gears there is a slight jerk that old honda autos are known for, my wife's car is a 01 celica gt which I bought 2 months ago and went through castrol import ATF 3x drain n refill method suggested by honda for their auto trany, I attempted the same thing in the gts and the shift jerk went down a little but not by much, the gt auto tranny is so smooth I can't even tell whenever it shifts up or down other then high rpm engine noise when it gets there. Is it the engine being much more powerful then the gt to cause that jerk? Should I try a different fluid? Need to know if theirs is smooth across all gears in any rpm range.

Huge problem. Everything was fine the first couple of times I drove today.
Tonight, when I was getting in the car, it turned on. I tried to change it from Park, but it just stuck and wouldn't move and let me change at all, even down to reverse. It's just stuck in park.
What is wrong with it? What's stuck, and what can I do to get it unstuck? Or else, I'd have to get it towed because it won't budge from park
Volkswagen - Jetta :: Automatic Slipping Gears - Car Jerk Forward And Make Popping Noise
I have an automatic Jetta and just hit 130,000 miles. Recently, my car would randomly after I turn it on and put it in drive, the car would jerk forward and make like a popping noise. Then the car drives fine as usual. As if the gears are slipping? Is this a sign that my transmission is going out? What else can cause this? What should I do?

I have a 07 20T and today when I went to pass someone on the highway I punched the throttle and the car rev'd up and it started to jerk really hard as if it was not catching the next gear. So I let off the gas and everything went back to normal. Under normal driving the car drives normal and fine, its only when you give it some hard throttle and when it hits high rpm's it jerks, it feels like the car wants to stall. I have 30k miles on it.
View 15 RepliesGolf IV / Jetta IV :: Under Hard Acceleration In 3rd - 5th Car Will Jump And Jerk
I just recently bought a 2001 Jetta with the 1.8t (AWD) because it had low mileage and a reasonable price. I've never owned a VW before so I know very little about them in general. This is my second vehicle with a turbo, my first was a Saab 93.
When I purchased the car it had the check engine light on and the codes were Vehicle Speed Sensor and Secondary Air Injection Pump. I was able to get it to stop throwing those codes just by cleaning off the components and reconnecting them. The only predominant problem I've been experiencing is that under hard acceleration in 3rd-5th the car will jump and jerk. Its almost like the car isn't getting enough fuel/air but I'm not entirely sure if that's an accurate diagnosis. I've ruled out transmission issues because there are no problems when driving at a slow-normal acceleration. Any insight on where I should begin to fix this issue would be welcomed because I feel as if my motor mounts will break due the force of the jerking.
My last issue has to do with what happened yesterday. My check engine light came back on randomly when I cranked my car. I had no issues the previous day (besides the aforementioned "jerking) so it seemed odd but what really worried me was when I started driving. Whenever I would release the accelerator the car would slow down suddenly as if I applied the brake. The problem continued throughout the day until I got the codes checked and they read Vehicle Speed Sensor (which I've seen has numerous issues from the factory installation) and the Bank 1 O2 sensor. Today I started my car and the check engine light wasn't on.
My car drove like normal (still the hard acceleration jerking but no dramatic deceleration when I release the accelerator). Now to my question, can an O2 sensor cause a problem like this? Maybe the MAF is bad? Not even sure if this vehicle will throw a code for the MAF ...
Santa Fe (CM - 2007-12) :: Strong / Hard Jolt Or Jerk
I'm experiencing a weird problem with my 09 Santa Fe (just under 15k miles). A few times, while in slow and heavy traffic (and ONLY then) I experience a hard jolt or jerk. The 1st time it happened I thought someone had hit me in the rear but that was quickly ruled out.
I suspect this has something to do to do with the tranny. Though it occurs maybe once or twice monthly, I am beginning to have concerns and suspect that the problem will get worse with time.
Sonata NF (2006-10) :: GLS Hesitation On Hard Acceleration
I have a 2010 Sonata GLS 4-cylinder approximately 124K miles which has been hesitating on hard accelerations for about 8 months. It will usually do this when getting on an on-ramp for the freeway or if I need to do a U-turn and get up to speed quickly. What happens is I punch the gas and the vehicle acts as if it's not getting any gas and hesitates or stalls and then it finally takes off. Usually I see a cloud of grey/white smoke behind the car enough that I am unable to see any cars in my rear view mirror.
I do not seem to see a difference when the vehicle is warm/cold. I do not have a CEL nor have had one. I have replaced the MAP sensor, PCV valve and spark plugs (properly gapped). I have done a compression test and am getting roughly 180-185 psi per cylinder. I am not experiencing any oil loss/coolant loss, do not see any oil in the coolant or gummed-up or oily spark plugs. I have also replaced the transmission fluid, doing a drain and flushing the torque converter. I have also cleaned the throttle body, and am using a new air filter and the oil has been changed within the past 1000 miles.
Sonata NF (2006-10) :: Hard Downshift When Cold
My 2010, 4 cyl. auto started giving me hard downshifts awhile ago, when cold. Mainly going from 4 to 3, and 3 to 2. I had the tranny fluid changed a few months ago at 56,000 miles, but no difference. So, that left me with the dealer and this is their diagnosis:
Updated ECM and TCM and hard shift still present. Vehicle will require new PCM (TCM?) to resolve problem.
Sonata NF (2006-10) :: Hard Shift From 3rd To 2nd Or 1st During Deceleration
