Touareg :: V8 Transmission Lurching Forward On Upshifts Under Moderate Acceleration
Mar 22, 2004
I've been told by my dealer that the 6-speed transmission in our rigs is known to shift roughly. They have therefore pronounced my truck healthy. However, I don't think I believe it. I've never seen a vehicle that lurched forward on upshifts under moderate acceleration. It behaves if I punch it. It behaves if I accelerate like my granny. Anything in between and I get a fairly violent jump at each shift point. At times, in stop-and-go traffice, I have thought the truck would jump into the car ahead of me. This behavior seems to be unrelated to which transmission mode I'm in. D, S, and Tip all do it. I love the motor in this thing, but I'm starting to hate the tranny. What should I tell the dealer to look for on the truck that might be causing this? The truck is going in next week to replace a fog light with condensation, so I'm hoping to get them to look at it then.

My 2013 goes 7mph with the foot off the gas. Why is it doing this and is there any way to correct this?
Is this normal? I have to keep my foot jammed on the brake to stop the car from lurching forward.

I have an 04 V8 and have consistently noted a valve(?) clatter noise under moderate to hard acceleration. I mentioned it to my VW sales associate and he stated this is typical of this engine and that after warm up it should no longer occur. I hear the clatter at any time, warm or cold.

My car has been having a cool start acceleration problem in the past couple weeks.
After I start the engine, switch to D ("Drive"), and step on the gas paddle half way, the car will go forward for about 1 feet. Then it will choke for couple seconds. If I release the gas paddle and then step on it again, it will do the same thing.
However, if I just slightly step on it and let it slowly accelerate, it will be fine. Also, it only happens on a cold start.

This is an issue when I brake over a small bump or pothole. It lurches forward and I feel like I have lost control of the brakes and we are about to crash into the car in front of me. Seems like this is an issue with other Prius years but I thought this was fixed with the v.

I have a 2007 Passat 2.0T wagon. I got gas this am, and on my 30 minute drive to work all was fine until I got into traffic or came to a stop sign. While at the stop sign the car started to lurch forward or even seemed to be up and down. The idle was fine, completely constant. It was like the car was hopping or wanting to push forward. It did not happen in reverse or neutral and the car was fine while driving. What this could be?

2002 Santa Fe has been misfiring for about a month...yesterday it got worse...When it's running hot and stopped at intersection it lurches forward.. It stalled when backing up after being parked. Mechanic did diagnostic test and it showed zero...He changed 2 wires to spark plugs..Spark plugs have only 20,000 miles and SUV has 68,000 miles.

My 2002 Buick Lesabre has about 160,000 miles on it I keep up with maintenance regular oil changes and what not. Today when I am driving to work and right as I get on the freeway my car starts lurching forward and slowing down repeatedly so I pull over turn the car off look under the hood everything looks normal to me. I wait a bit start the car up and the lights on my panel go from the dimmest they can be to blinding bright and I could not adjust the brightness at all. Any way the car drove fine the rest of the way but the lights were bright as can be the whole way there. What could be causing this? Bad battery?

I frequently experience a short "pulling" like a course correction when the rig upshifts to 5th while accelerating in casual turns but only between about 35-40 MPH. Sometimes barely feel it, sometimes not at all but once a month or so, I get a good "pinch", enough to eb a bit scary in narrow lanes and traffic. Seems to only do this when accelerating from a stop, don't notice when driving on windy roads, etc.
No pulling while driving straight, braking or accelerating. Aligned twice by two different experienced people (knowledgeable of the air suspension) in two different places, new tires and rims, stepper motors hear and there thru the lifetime, with or without ESP, Sport, Normal or Off-Road height. Is it the self levelling kicking in, pitch/yaw sensors, ? Absolutely only in turns while accelerating and when it upshifts to 5th.
2004, air suspension, all stock, V6

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.

I bought a 2003 Jetta with a 5 speed automatic transmission (09A tiptronic) but it upshifts and downshifts really bad, it doesn't matter if it's cold or warm. After reading a lot of posts in here I thought that what was wrong with the car was the valve body on it, so I bough a re-manufactured valve body and replaced the old one. When it was in the shop I was told the wiring harness was burnt/fried so they replaced the harness too. I got the car back and it still does the exact same thing, so I don't know if the transmission is bad or maybe it can be a bad TCM. What could be wrong with it?

2012 2.5 SE Auto 53,000 miles ... A few days ago I started getting very hard downshifts and long upshifts. The downshifts were hard enough that the person at the dealer didn't make it out of the parking lot on the test drive. Most noticeable from 3-2 and 2-1. 1-2 is hard and 2-3, 3-4 and 4-5 take a few seconds to happen. No lights or limp mode.
In recent months I was getting a thump about a second or two after coming to a stop. Enough of a thump that the car would move forward if I didn't have my foot firmly on the brake. They flashed something(the ECU?) claiming there was a TSB for my complaint but it didn't seem to make a difference. I bought the car with 40,000 and the trans never felt right to me. I had them change the fluid just before 50,000 so they couldn't deny a claimed based on failure to maintain.

Was back east this past weekend seeing some family. Went out with a friend of mine, who has lent me his 2011 DSG GTI APR Stage 1(car currently has 24k miles) many times in the past and it has always performed flawlessly.
We were out the other night and the car hesitated under moderate acceleration between 3500-4500rpm in second and third gears. It almost felt as though it was bucking a little, really odd. The hesitation comes in threes or fours, then moves on in the revs.

I own a 05' MCV36R and have noticed a strange acceleration issue in the past few months. In low gears the car seems to be lurching back and forth. The RPMs are consistent with this jumping up and down. The car doesn't have any issues when travelling at faster speeds, but perhaps i'm just unable to tell.
I first noticed the problem when travelling at about 60 kmph along the straight bit of road outside my house. At this constant speed the car seemed to lurch forward and backwards slightly. I also notice it when turning corners at low speeds, for example in car parks.
I did a test yesterday when first taking off. I travelled at 20kmph for a reasonable distance and found a speed/ rpm combination that magnified the issue.
I spoke to a mechanic and he said that the throttle body may need cleaning out. I have since done this and it hasn't resolved the issue.

2011 SF. 52000kms.
A little while ago I noticed a brief vibration (felt through floor and steering) with normal acceleration from stand still... I attrributed this to the cold weather and perhaps oil thickening, as the problem went away after the car was warmed up. Since then I have noticed that it's continually happening on a regular basis, but only for a short period.. I was still thinking that it was the cold, but that wasn't the case because I left the car idle at start up for 20 minutes until well warm.
Now.. If I slowly accelerate (not putting much load on the car) there is no vibration at all. When the car reaches a certain speed, the vibration goes away. There is also no vibration after about 15 minutes of driving.
I had a neighbor test it with me to confirm and he felt it, and initially thought differential oil, but then suggested myriad other things from the CV boot to bearings to etc etc.
I need to take it to the dealership so they can experience the vibration but would certainly need to leave it there over night so they can check it out when "cold".

So, my 2004 with its constant tick is now "Missing", but only under moderate acceleration, between 1k and 2k rpms. i.e., : When in OD and wanting to gain a few MPH, but not drop down a gear. I have noticed it in OD and in 3rd. Feels like the engine stops for a split second, several times.

I took my Phaeton in for a transmission noise and they are saying it's "normal" for V8 Touaregs and Phaetons to have this noise on downshifting under acceleration from 4th to third at around 40 MPH. Yes?

Is this behavior normal: I test drove a 2010 corolla LE with 4-spd auto, 41K miles. Noticed that on level highway 60 mph that whenever I eased up on the gas that the RPMs would shoot down. Vehicle speed was barely decelerating since I was on level. As soon as gas reapplied (gently), then the RPMs would shoot up. I'm guessing the delta was like 300 RPM. I get the impression that at highway speeds the car is mostly in 3rd gear or shifting up and down a lot. I've read a lot about a TSB for 2011 corollas but nothing for 2010. And I think that problem is different. So my question is whether this is "normal" for driving at highway speeds?

I have a 09 Subaru Forester with 66k miles that vibrates like it is going over rumble strips when it up shifts from 3rd to 4th gear. It occurs under normal (not brisk) acceleration. I had the trans fluid changed at both the 30k and 60k services. I have owned this since new. It began before the 60k service. Also, sometimes the tach will increase revs during this as well. I don't know if this next thing is related but when I once need to merge quickly into interstate traffic I gave it a good amount of throttle and the tach revs increased but the trans did not follow with an immediate down shift.

I have a 2007 Camry SE V6. Under moderate to hard acceleration, it sounds like a deep throaty sound coming from where the intake/throttle body is located, almost as if I have a SRI, but I do not. I checked for anything loose, hoses, airbox, etc. Then checked the intake resonator below and to the left of the battery, all seemed normal. Everything seems normal! Only happens when I push the accelerator a little more than usual, for example, when I go on the highway.

My 2010 III, not 3 or Three since it is a 2010, will brake loose the tires when wet with moderate acceleration. If i floor it it will alternate spinning right to left until I back off the throttle. I"m not really complaining since I had an 08 that would not spin a tire and could not be driven in snow. Just wondering if this is normal on a 2010.
I turned right with moderate acceleration on wet pavement today and the tyres broke loose and the car was headed for the curb. Oh the traction control light does come on when this happens but, no brake application or engine speed reduction.
