Subaru - Forester :: 2012 Auto Transmission Jerky - Sluggish Acceleration And Rough Start
I purchased a 2012 Subaru Forester 2.5X Premium (automatic transmission) in November 2011 with 4 miles on it. Since the get-go it has had issues, but we thought that some of them might work themselves out as we broke the car in (which we were religious about). At the first oil change, we told the dealership about the issues we were experiencing and got the expected "the computer doesn't say anything is wrong" and "we couldn't replicate the problems" excuses. We were told to bring it back if the problems continued. Well, they've gotten worse. Here are what we are experiencing:
- Erratic shifting. I commute from the mountains to the city every day, so I need power from the car. Sometimes, when I'm heading down a hill and I tap the gas slightly to give myself a little boost, the car will suddenly downshift, even though it was sitting at 2500 RPM and didn't need to get any extra power beyond more fuel. Going up the hill is worse, as if you are not actively accelerating (including if you are trying to maintain a constant speed), it will upshift on you and you lose all power, so it will need to downshift to make up for this. It does this constantly for the entire drive home. Everyone who has driven this car in the mountains has experienced this.
- Jerky transmission. When the car shifts, it is super harsh and tends to throw you forward or back. Even when on flat ground it shifts roughly.
- Sluggish acceleration. If I give the car any more gas than I usually do, it hesitates before going anywhere. One day I needed to get over on the highway fast and floored it - it took the car about 2 seconds to respond. Then, yesterday, we were turning on to a highway from a side road and I tried to accelerate (gas about 1/2 way to the floor) and it didn't respond at all for about 5 seconds and the "Check Engine" and the traction control lights started flashing at me. We were on a paved road with no gravel, water, ice, etc and the traction control light began flashing on the straight, not while we were turning. There are also days when it feels like there is an anchor tied to the car and it just doesn't want to give me any umph at all.
- Rough starts. This is the really weird one as there is no rhyme or reason as to when it happens. Some times it takes the car several revolutions to turn over. Oddly, it's never on the really cold (under 20 degrees F) days, but it has happened when it is ~35 degrees and a couple of times when I have started it in the middle of the day to grab lunch and it is ~65 degrees out.
- Running rough. This usually happens after a rough start, but can also happen at other times. It just idles very rough and won't calm down. These are the days I have the worst time with the shifting issues.
I had a 2001 Forester that threw a rod, which forced me to get this car. Everyone who has driven both agrees that the 2001 was quicker, easier to drive, and had more gumption than the 2012. It also had less problems even though I purchased it used in 2005 (until the whole rod-throwing thing, of course). I really want to love my 2012 Forester, but I am so upset that, for the first time in my life I have a new car, and it runs terribly.
Golf V R32 :: Transmission Jerky - Clutch Slipping When Start Going From Dead Stop
So I took my car in for the recall last night and also told my service advisor that my transmission has been a bit jerky lately. Kind of felt like the clutch was slipping when you start going from dead stop, and clunk here, clunk there.
After their diagnostics it seems to be the Mechatronics unit, apparently about 50% of our cars had the issue. The part would have to be ordered from VW due to it being made per VIN and is on back order. They didn't have the reacall parts in stock so I had to leave my car there. Stuck in a bright red Jetta now.
Camry 2012+ :: SE V6 - Jerky Shift From 4th To 5th Around 40mph While In Drive
I just wanted to see if others are experiencing a hard kinda jerky shift from 4th to 5th around 40mph while in Drive. It's not super bad but noticeable when light on the accelerator. The shift to 5th drops engine speed to around 1100rpm.

So a few days ago until now I've noticed the transmission jerks as I am driving, like a slight stall and such. Could this mean my transmission is failing, I feel as if the car chokes. My car currently had 8900 miles, all highway driven.
While I was doing some reading, I noticed some people had their ECU resetted. Also my average mpg is 10 mpg on a v4.
Passat (B6) :: 2006 2.0T Transmission Jerky When Upshifts From 1st To 2nd Gear
I have a 2006 Passat that I love but it's been doing something since it was new that has finally bothered me enough to do something about it. When the automatic transmission upshifts from 1st to 2nd, it feels really jerky - I don't know how else to describe it. It's like it surges and other times feels chunky. It seems worse after the car has sat overnight or during the day at work however it still does it even after being warmed up - just not as severely.
I called my VW dealership and spoke with a service rep and he suggested allowing the car to warm up for a few minutes before driving to let the transmission fluid 'pump' or something - not exactly confidence inspiring and even if that worked, not a good solution. The good news is that it doesn't work any better after doing that so I suspect something is actually wrong and hoping they will find it before it gets worse. I have an oil change this Thursday but based on my discussion with the service manager, I don't know that I am going to get very far with them.
Accent MC (2006-11) :: Jerky Gear Changes From 1st To 2nd - Automatic Transmission?
So I have a 2006 Hyundai accent with 75000KM on it. I notice when it shifts from 1st to 2nd gear sometimes it will jerk. It feels almost as if it goes to neutral and then sifts, causing the whole car to jerk. It use to only do it when the car was cold (first 15 min of the day) but now it seems to be doing it all the time and getting worse. I have had the transmission fluid replaced, but it doesn't seem to work.
View 30 RepliesSonata I45 (LF 2015+) :: Automatic Transmission - Jerky Downshift From 3 To 2 And 2 To 1
So the problem is that I have a jerky downshift 3-2 and 2-1 that can be felt by everyone in the car (car pushes forward on downshift) until the car warms up. When the car is warm I can feel it slightly at times and feel a clunk when shifting down 3-2 and 2-1. On up-shifts at times the shifts are shaky from 1-2 and 2-3. I have brought this forward to my dealership as well as another one. They all performed software updates and reset the adaptive learning. However every time I got my vehicle back after this procedure I found the A/C was on full blast. So the initial drive by the tech after the reset was learning while the A/C was on. Would this be causing the weird shifting I experience while the A/C is off. I seem to notice a better shifting when the A/C is on but this may just be me trying to reason why my transmission is behaving this way. I drove other 2015 Sonata's and they have much better shifting than my car and no hard jerks on downshifts.
Both dealers have felt the downshifts and have come back and simply said "We've done all the updates and reset and learning. This may just be a normal characteristic of the car." I told them that a brand new vehicle in this day and age shouldn't be shifting poorly when compared to an older vehicle with 300,000 km (my old Honda Civic which are prone to transmission failures). They responded casually saying you can go and get a second opinion from another dealership if you like. I am furious with their responses and just left it at that. I need to know how to get this resolved and if this is indeed something I should expect from my Sonata.
Touareg :: Transmission Slow On Upshift And Jerky On Downshift
Transmission (V-6) is slow on the upshift; and jerky on the downshift. Going uphill, the transmission does not want to downshift into a lower gear unless the accelerator is heavily depressed. So, 6th gear at like 45 mph uphill, then finally downshift into 4th with jerk downshift.
As car comes to a stop, right about 2 or 3 mph, the rpm's drop from idle to about 400; sometimes once sometimes twice. It feels like it's going to stall. Have had all the software updates.
Phaeton :: Transmission Malfunction - Surging / Jerky Intermittently?
Currently on a 1 week mini break, and the P has decided to play up. I have had 6 months of worry free driving before this new issue. I have posted before that the 6 speed in my P has never been the best behaved in auto, a bit slippy and jerky, at times, but also perfect shifts 60+% of the time, but I know others share this issue so not unusual - its usually ok when manually going through the gears.
Upto 110k miles now and on this journey had been about 10miles in on the motorway so fully warmed up. Had cruise on doing about 70 mph. Bascially started being very erratic and surging then dropping quite uncomfortably.
I knocked cruise off and observed that under full acceleration no issue. Under no acceleration (foot off gas) no issue. Only when keeping up with traffic, so partial gas, did the issue occur. I waiting for the next exit and pulled off, and it initially carried on even at low speeds around 30mph, then went away. Parked up. Started it up about 2 hours later fearing the worse, but had no issue since. Kicking myself as I have the laptop but forgot the VAGcom lead.
Rang my VW specialist and he said as there were no MIL lights, the only way to know whats going on is to scan the car, and if it does it again get it recovered, which will mean the end of my break. I will scan the car as soon as I get back, but concerned I could do more damage.
Prius (Gen 3) :: Jerky Motion When Driving On Highway At About 50 Mph
Was driving today on the highway at about 50mph and suddenly noted jerky motion. Kept the right foot steady, but it seemed like extra power was being delivered and then cut off every few seconds. The MPH monitor was jumping all over the place with the jerking motions, as was the HSI power scale indicator. The jerking was not terrible, but noticeable.
Got home safe, no issues otherwise. Only noted while cruising on the highway. No issues driving in the city.
I am in the midwest and the temp yesterday was -11F and today about 0F. Did not a problem yesterday, but then again was not able to drive at 50mph on the highway due to snow until today.
Prius (Gen 3) :: 2012 - Jerky Acceleration From A Complete Stop In Summer Heat
My 2012 Prius Two did something odd today that it's never done before. Today, after leaving a meeting, I had two instances where accelerating from a complete stop was met with a delay followed by a jerky and sudden acceleration. This only happened twice out of the dozen-or-so complete stops I made. This only happened on my first couple of complete stops, then never did it again.
Here is some pertinent information:
- Silver Prius, no tint
- Car sat uncovered for about 2.5 hours
- Was 96 degrees outside, not a cloud for miles
- Turned the car on, opened the front two windows for hot air escape
- Turned the AC on to full
- Sat parked but car running for maybe 30 seconds before reversing out of parking spot
- Rolled up windows
- Battery fan was going strong
- No indicator lights came on to suggest an issue
- Happened on my first two complete stops at stop signs
- Never happened again
- Battery fan eventually simmered down
- Have 55,000 miles on the car
Camry 2012+ :: Driving With ECO Button On / Transmission Does Not Get Smooth
I own a Camry SE 2012. Like a title above, driving with the ECO button on? I used to turn it on all the time, however, I've noticed something strange on my car recently. The transmission doesn't get smooth! I mean with the 6-speed auto transmission, it is supposed to change speed smoothly from 1 to 2, 2 to 3, respectively. It's like when I change from 1 to 2, the transmission is smooth enough, however, when I get to higher, it doesn't get smooth. I'm not sure if I turned the ECO drive off and it would get better or I just feel it so. My first thought was about the engine oil was not lubricated and out of date but I did maintained a week ago. It still happens on my car, but less than before.

Car intermittently shifts very rough and jerky. Just took on a long vacation trip and every AM when it was cold it shifted hard them smoothed out once warmed up. Got home and now it is doing it all the time. Dealer said do the trans flush...I did it and it made no difference. Is this a common problem with this model? Mileage is 39,800...not sure I want to buy this car at lease end.

I just bought a brand new 2013 Elantra! I love the car, but over the past week or so I have started to feel the car's transmission (auto) jerk when it shifts from 3rd to 4th gear. I feel the car hesitate somewhat when going from 3rd and then jerk into 4th gear if that makes any sense. The car has less than 1000 miles and it never did it when I first bought it. The transmission was always smooth until recently. Also, when coasting down the road I feel the car jerk forward when I give it some gas which also feels very strange to me!?
View 37 RepliesTouareg :: Transmission Shifts Into 5th And Stays There Or Extremely Jerky Downshifts
My beloved Treg is marooned at the dealer again, having been towed there this morning. Transmission is all over the place...shifts into 5th and stays there, or extremely jerky shifts - especially downshifts. Gear position indicator is highlighted in red and no longer indicates which gear I'm in. Check engine light is on; no message in MFI...
Incidentally, it appears that the dealer and/or VWOA is starting to understand how to treat luxury vehicle buyers. Roadside assistance was very responsive and courteous. Dealer set me up with a rental from Budget...made a point to have me pick something similar to the Treg (not a POS econobox). I'm driving a Ford Exploder...a far cry from the Treg, but at least it's an SUV and has similar seating and hauling capacity.
Lexus LS 2007+ :: LS460 Transmission Would Shift Hard And Jerky Almost Through First 3 Gears
So I recently purchased a 2007 LS460 with 115k on it. I've noticed that about a month ago the car started driving pretty weird. The transmission would shift hard and jerky almost through the first 3 gears, like driving a manual.
Also, when I tried to floor the car from maybe 40-50mph, the rpm would shoot up only 500 then downshift and accelerate causing a violent jerk. It feels like if I was driving at 50mph on 8th gear, when I floored it the car would feel like it downshifted to 7th gear for merely less than a second and downshifted again to 4th gear causing the car to jerk hard.
This is the car's history:
- Reset the ECU by disconnecting the battery (no luck)
- Auto transmission software has been updated at the dealer
- Valve springs recall has been completed
- Head covers has been changed
- Engine module has been reprogrammed by the dealer at 70k miles
- Trans fluid has been changed at 70k miles according to lexus.com service record
So at this point I really don't know what could cause this problem anymore, maybe it could be the transmission fluid?
Chrysler - Towncountry :: Speedometer Jumps Wildly And Then Goes Clockwise - Jerky Transmission
2002 Chrysler Town and Country. My speedometer jumps wildly and then goes clockwise and rest without working. The trany hesitates and has a jerking when sitting in drive, and slow to shift into 2nd gear. We have replaced speed sensors, wiring and connectors, and now are thinking the chassis control box may be next.

One day I was driving my truck 96 f150 4x4 Eddie Bauer edition and the over drive light started flashing and the truck got jerky going up hills. I got home and hooked my code reader up and (p0708) it said transmission range sensor. I replaced that the next day and drove it around town for about 30 minutes and parked it all seemed to good. But the very next day I started down the road and the transmission was slipping very bad after I turned around after a few hundred feet I barley made it back to my house. I checked my transmission fluid it's full and doesn't smell burnt or anything, I double checked the alignment on the neutral safety switch I just installed and it still in line. So I'm thinking my transmission is going out...
View 4 RepliesToyota - Camry :: 2002 - Jerky Motion When Driving On Freeway And Check Engine Light Came On
I have 2002 camry 4 cylinders and has 175,000 miles. I was driving on the freeway and suddenly I felt a jerky motion and check engine light came on. When I stopped at light the car began to vibrate and when started driving at low speeds it got me home. Admittedly I had put lot of hard miles on the car in past 6 months and I was lazy in getting oil changed in time. It might have been 7000 miles since oil chg. I took the car to local oil change place they did not mention anything about engine but they said my transmission oil was dark and burnt. They said I should flush and replace. I agreed and tech said he had to do second flush as oil was still dark. After second flush, he said its little bit better.
I was hoping this would solve my problem but unfortunately no. Car was still vibrating and when i drove at slow speed it was driving but as soon as I tried to accelerate the car lost power. Check engine light has been on since the incident at freeway, but now check oil light and battery sign came on. The power steering lost power. I had to park the car and restarted, as long as I drove very slowly it would drive but if I tried to accelerate where the rpm went from 1 or to next level car would loose power with warning lights on. I had recently replaced fuel pump, filter and any repair which was suggested to me. Admittedly I have not done timing chain or belt.
