Lexus LS 2007+ :: Slight Shutter Or Jerk - Downshift Rough When Slowing
Feb 3, 2014
Had a slight shutter or jerking feeling in their LS, sort of like the rotors are warped, when they slow to a stop from 40+ MPH? I just cannot make the car stop smoothly no matter the amount of brake pressure I apply.
I can 100% eliminated the issue if I shift the car into neutral before I slow down. So it has to be the the transmission not downshifting smoothly. Done it from day one. I even replaced my rotors and brakes so I know that isn't it.

I got off the highway today and was at a very long light, but enough time to feel my car making slight jerking movements and i saw the car raise a little over an inch.

When I'm slowing down, usually about 35 mph which i think is going from 3rd to 2nd gear, there is a noticeable rough down shift. Nothing horrible, but definitely much more noticeable than the shifting of all the other gears.

Few weeks ago I bought my first Lexus, an '07 GX 470. It has roughly 75,000 miles on it, 2 previous owners before me. Anyway, I hear a noise sometimes which either sounds like a slight belt slip or fuel being pumped into the injectors when I give it a good amount of gas and the engine downshifts to accelerate. I had the dealer replace the drive belt(serpentine belt) because of 2 reasons, it needed to be replaced and I thought that could be the problem(I did not have to pay for it since I have had some problems with the Lexus dealership I bought it from, they did it as a "goodwill" gesture, that's a story for another thread) and inspect the tensioner and pulleys, they said the pulleys and tensioner were in good working order.
I drove the GX home tonight after said replacement, and I still noticed the same noise. The best I can describe it is like I said above, a slight belt slipping noise or it could also be described I guess as fuel being injected under acceleration as soon as the trans downshifts to accelerate. I am just curious if this is normal for this engine or do I have a possible problem? It's covered under the Lexus used car warranty for another 5 months so if there is something wrong, obviously I would like it fixed under warranty if something is wrong. One thing I should probably mention is, the noise is semi quiet and I guess the average person might not even notice it.

For the most part, I'm pretty happy with my 2010 Santa Fe SE (V6 AWD Automatic).
When I'm coming up to a yield sign, or otherwise slowing down to say 5-10 miles an hour but not a complete stop, and then when I start to try to go again, there is a hesitation and then the vehicle kind of jerks as it starts. It's like it takes a half second to a second for the throttle to respond, and by then it revs higher than I expect. I don't know if it's the throttle delay or a delay downshifting before it starts, or a combination of the two.
I've also noticed that a half second or so delay when just sitting in park and quickly pressing the throttle and releasing. I can press the pedal to about 50% and release it before the RPMs respond at all. Then it'll rev up and back down as you'd expect, just not WHEN you'd expect.

Here's the deal:
1. My 2002 SC430 with 23,000 miles on it is making a low rubbing noise when slowing down, with a slight vibration, not severe enough, but it is annoying and frankly surprising on this car. The dealer tells me it's because the brakes have "glaze" on them, and short of a new brake job, you can jam on the brakes to clear or loosen some of this and reduce the noise. ( I live in the desert so I'm sure I could find a deserted stretch or road for this craziness...) The dealer reports the brakes have 70 - 80 percent life on them and I don't need a brake job.
2. Power steering. I thought this particular car was just hard to steer, but even the tech at the dealer commented it's like I have no power steering. I test drove two other cars, and the steering is markedly lighter on the other two SC430's I drove. (2002 and 2005) Dealer can't seem to find an explanation, but I have to drive this car with two hands around town... I know this is not the way this car was intended to feel.
I don't believe the car changed that much from the 2002 model so as to affect the steering. BTW, I'm using stock tires, not run flat, 4 months old. And the steering is stiff at idle anyway, regardless of tires. The first SC I drove, which sealed the decision to buy one, was so quiet I didn't know the engine was running, easy to steer, and smooth.

Read a few references but nothing seems the same as what I have... 2001 Ford F150 Larite 5.4L 4 x 4
When slowing down, at speeds of 3 to 4 miles per hours truck starts to shutter. It is not an engine issue, nor a brake as it will occur with brakes on or not applied. Engine is running smooth, seems more mechanical that fuel or brake related. Shutter is not slight either.
Both CV axles, hubs, rotors and upper and lower A Frames have been replaced. Shutter was happening prior to the replacement, they were replaced as preventive maintenance. Shutter is profound enough to shake the mirrors. What it can be.

I don't do too much long range driving but i notice about a week ago i was driving about 70mph for about 40 to 50 miles.. and when i got of at the exit i started to slow the car down and during the down shift i felt the car to a little jerk and clunk with a bit of hesitation during it.. Today i was doing another long trip and it did the same thing..
i use the highway a lot but usually on it for maybe 5 to 10 miles and it never does it.. I called the dealer and explained it to them and he said he would have to drive the car. and i know since it only happens on 40 plus mile trips the dealer isn't going to go for a test drive that long..
The next long trip i have might be tomorrow nite headed to AC for some gambling so i am going to try to remember to bring my camcorder so i can try to record it for the dealer..
car is a 07 wolfsburg 2.0t automatic completely stock..

i have a 2010 with 182k miles. The vehicle will jerk like the drive is engaging and disengaging several times (repeatively) when going down hill. It doesn't matter how fast, but I notice it does depend on the ECO indicator. The ECO gage always indicates above the mid mark but ranges between no more than quarter to an inch and quarter above. If I speed up it stops and if I slow down below the mid line it will stop.

Or just can I just replace and go. I'm having some issues with trans on my 06 gs430. It's having a downshift clunk/jerk when coming to a stop. I just purchased a used trans, but would like to see if it could be ecu related. I have seen other comments from other member that they replaced the trans, but still the issues were present. Some stated that there was some issues with the ecu holding the trans solenoid longer then the usual.

I have had a few times when my 2013 Chevy Traverse LT suddenly jumped to a low gear while quickly slowing down, causing the RPMs to jump up to 4-5000 RPMs. It remains in that gear until I am practically stopped. Is this normal?

Notice roughness/jumpiness in the transmission when slowing to a stop, or crawling along (like in a shopping center)? it's quite evident on my car, and perhaps i just have a problem that nobody else feels.
It's as if the tranny is downshifting when slowing to a stop, and I can really feel it...makes it difficult to come to a smooth stop. and then if I'm moving very very slowly in heavy traffic, it seems to be "wandering" between 1st & 2nd...something like that...and it's very jumpy. Not smooth at all.
I realize that Lexus may come up with some reprogramming for trannies (that happened on my '01 GS, and it made a big difference).

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.

I have a code P1740 that sets after a couple of drive cycles. This is preceeded by a flashing "Overdrive Off" light, until the MIL eventually comes on.
The only driveability symptom seems to be a premature downshift into first when slowing down. When cruising at highway speeds, I can turn OD on or off using the switch on the end of the shift lever and all appears OK.
Could it be the OD solenoid, and if so is this something I could change myself?

Shortly after we got our 08 ls460 my gf asked if I had felt a weird brake issue. She said it was like the car would "jerk" or "bump". The way she described it was more like how a car with an auto tranny will "creep" if you aren't holding the brake pedal down firmly. Yesterday I was driving the car, with her in it. Stop at a light. All is well. Brake off, gas on to leave...It felt like someone hit us on the left rear of the car. I actually stopped and looked behind us to see what the hell happened. She says "that's the feeling I was telling you about". When we got the car I had it on a lift and noticed the left rear sway bar link was broken, but there was no damage to indicate a reason. I can't find anything else on this problem anywhere and can't tell if it's brake related or trans related. Our local lexus dealer is going to check it out on wed at 9am.
Calipers were in great shape when I did the brakes with no hanging or signs of trouble. Everything works like it should 99% of the time. But damn if that 1% won't scare you.

Hate to make a question like this my first post here, but anyway. Just got an '11, 5L, Scab, only have 350 miles on it and absolutely love this thing. Since I've never driven any other '11 F-150 I'm not sure if what I am feeling is normal or not for these trucks. With a light foot, driving around town my truck feels like it has a very slight shutter just before the 2-3 up shift or between 20-25 mph.
I have felt it in the 1-2 up shift but it appears to be intermittent but almost 80% of the time. Had a cup with ice-water in the cup-holder and exactly between 20-25 mph on the 2-3 up shift the water in the glass slightly ripples and caused the ice to slightly chatter. Is this normal or should I take it back and have Ford look at it?
Oh forgot to mention if I give the truck more aggressive throttle pressure I can't feel it, only seems to be low speeds, such as driving through a neighborhood or parking lot. I hoping it just needs to be broken in yet.

2008 LS600hl with 30K miles, when de-accelerate/brake I hear like jet engine slowing down sound, I think coming from the CVT/Electric motor area.

Starts fine, loud motorboat like noise ... then car hesitates when put in any gear for a few seconds before moving ... then drives fine. Slight shutter at low speeds 30 and under....hit the expressway and its all good. Is that the fuel pump, a relay, what? It has a brand new radiator, gasket, thermostat and cover...so its not the cooling system.
Also...the check engine light is on, the pcm code says its only issue is the cat con...I don't think this issue is related cuz it was already on when the radiator killed in the middle of the highway....the noise is new. The hesitating isn't....that's been going on since before the check engine light came on....but its getting worse.

I drive 07'es350 and I have felt jerks while driving usually when accelerating or slowing down from speed. Did check with dealer before for transmission after analysis by technician he said it is perfect, recently read on internet and saw fuel filter can be an issue but when called the dealer he said filter is in gas tank and it is lifelong. Not sure what kind of diagnosis I should do to find the issue.

Team 4th Gen. Just a heads up. When I first bought my 600, the radar cruise was throwing an error due to a faulty brake light switch near the brake pedal. It was repaired but it appears the adjustment on that switch may not have been done.
I noticed cars rushing up on me as I was slowing down and turning many times, even causing a car to swerve hard to avoid hitting me.
I realized my brake pedal needed to be about 3/4 pressed to engage the brake lights. I also noticed I had to really mash the brake to disengage the cruise control. I then noticed when someone drove my car and came to a light. No brake lights even though they were def slowing down and not coasting.
So i had my oil changed today and had them investigate while it was there. There is an adjustment to that switch component and now the lights come on with hardly any pressure on the pedal and cruise disengages with very slight pressure on pedal as it should.

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.
