Lexus RX 2004-09 :: ABS Noise And Shudder Coming To A Full Stop
Mar 15, 2014
I've read about transmission shift problems between certain gears with these cars but don't know if my symptom applies. 2004, AWD with 35k miles, however mostly short stop and go driving.
When applying the brakes to come to a complete stop, there's kind of a abrupt downshift that I can even feel in the brake pedal. The car even has a last second little shake and a bit of a clunk..
Difficult to describe, so here's a short YouTube video as well. (you may have to turn up the vol to hear it)
Definitely not the transmission. Pulling the ABS/VSC/TC fuse , the car brakes normally. Skid control affects turning in curves and TC affects acceleration. So, it's ABS related..

My 2006 AWD RX330 rotors were starting to get warped so I changed them out along with new pads. I put new rotors in the front and new pads all around. Everything went smoothly other than getting the bottom rear slider pins to go back in easily.
Well it's been a week now and I noticed that if I press on the brakes at low speeds say 20-30 mph with a decent amount of pressure nothing too crazy there is a rubbing/pulsing noise right before i stop completely. It doesn't happen right when I apply the brake but right before the stop. It kind of sounds like the ABS is kicking in but i don't feel it in the pedal like you do for ABS or I don't hear the electrical noise you hear from ABS.

2004 Chevrolet Silverado 1500 4WD.... Rear brakes make strange winding sound when coming to a full stop, noise only apparent under 5MPH. They have been completely done over. Rear end issue? Changes gears fine, brakes work ok.

I noticed that I have an unusual "rumble" noise coming from the location of my ac blower motor when it kicks in full blast. When the air temp comes down a bit and the AC slows down or if I switch the ac off full blast under climate control, the noise goes away. I have never noticed this before and am wondering if it is my ac blower motor starting to fail.

Picked up my MK6 GTI DSG last Saturday. I have noticed a slight shudder when braking and coming to a gentle stop. At first I thought it may be the brakes bedding in so I kept it over the weekend. By today there's still no change. Is it normal for DSG transmission stop like this? Because I have never driven DSG transmission.

I am the owner of a 1996 Toyota 4runner. Recently, when I bring the vehicle to a complete stop, the entire SUV shudders, almost lunges, forward. At times it feels like the brakes are trying to re-engage. Could really use some pointers on this issue.

Driving into work this morning, I came up to the first stop sign before I get on the "freeway" and noticed a weird vibration. As I slowed to stop I could have sworn it felt like the engine was being lugged, the same feeling you get in a manual when you try to come to a stop without using the clutch. I thought for sure the engine was going to die. The engine RPMs dropped to about 800-900 RPM and once I got to a complete stop the RPMs went back to normal.
It seemed to do this every time I came to a stop. Could my torque converter be locking up and not releasing as it supposed to causing the lugging sensation I'm getting? The truck accelerates fine and idles fine once stopped, but when slowing I get that weird vibration and maybe the lugging sensation is just in my imagination and has nothing to do with the engine.
I do have a vibration from a missing wheel weight, but that's usually felt at about 34-35 mph. In addition, I also have a bit of a brake vibration when slowing down quickly, such as when slowing quickly from 65 to turn off the highway onto my local road, but this is a completely different vibration.

I have had my ecoboost for a couple months now. Overall I am very happy with it but I have noticed a shudder recently when accelerating and when coming to a complete stop at times. I only feel it when accelerating from a stop or when stopping completely. Kind of feels like something slips. I think I recall reading about this before on the 2011 and 2012s somewhere. What is causing this and is there a fix or is it just the way these trucks are?? I can deal with it but it is kind of annoying when driving in traffic.

From everything I have read I can't seem to figure out exactly what the fix is for what feels like brakes sticking after coming to a full stop, then accelerating? I will describe as a clunking and kicking feel, as if power to the rear end is being delayed then kicking in.
From all the posts and replies it seems like a differential issue. Exactly what the issue is and the correct fix? 2012 purchased used with less than 5K miles in 2013, problem has slowly been getting worse over time.

Have loud squeaky brakes noise when coming to a stop? It is very annoying. I took it into the dealer and they were able to identify a problem, but Lexus has no fix for it yet... have 3K on the car now...

I have a 2008 LS460 17,000 miles. I hear what I would describe as a clunking sound and feeling when coming to a complete stop. The noise and feeling is similar to worn suspension bushings. I took the car into my local dealer. After inspection they advised me there is a problem with my car because they heard the noise and feeling like I described. They also stated there is "no fix yet" per a service bulletin for the described problem. They also stated they don't know when a fix will be available.
It appears to be getting worse and my advisor stated he has another customer that's been waiting some time now for a fix. I'd really like to know the service bulletin so I can follow through with the repair by simply asking "Are the parts available for service bulletin 1234 yet? Perhaps others are also struggling with the same symptoms and yet to find a fix.

When I accelerate from full stop with 3/4 throttle when car gets to 60-70 mph it stops accelerating for 1 or 2 sec, there is is also a little jerk. After that it continues to accelerate normally. The problem is not present if for instance we drive 30 mph and then use 3/4 or full throttle. I talked to dealer and they said there might be a little jerk but nothing more, and it might be solved by software update. In my opinion its definitely not a slightly jerk, car completely stops to accelerate for a moment. Car has about 45 k miles so its almost like new.

Ok here's the situation. 2004 Santa Fe 2.7 AWD 170,000 miles.
I recently had to replace the front passenger side Drive axle. That was a piece of cake. However, since then the car has developed a shudder when it comes to stop (felt like the shudder on acceleration that was fixed by the dealer with a reflash). Suddenly it got so bad that it stalls when put into gear with the brake on. It feels like it is not coming out of converter lockup.
When I drained the fluid I replaced it with Valvoline Import multi-vehicle full synthetic (it says it is spiII). I latter added another half quart of Castrol transmax import multi-vehicle (also spIII). Did I screw up my trans? Will a flush work? Or do I just need to replace the trans and torque converter?

The other day, I changed my front brakes just the pads. Everything came out smooth but then later that day i started to notice a clicking noise coming from the passenger side brake I suppose. You can't hear it when you drive or when braking early but you start to hear it when the car slows down and your coming to a stop. Its a constant clicking noise within like 1 or 2 seconds of each other. Its not loud, but its very noticeable with music off. And not to mention, very annoying.
I'm about to take everything apart and reinstall everything to see whats up. BTW its a 2006 GS300 Front brakes. Finding a picture of the wheel off with rotors and whole brakes on. I think I might of put on a clip wrong.

I have been reading some mixed reviews here in regards to the "CLUNK". I am referring to that feeling as if hit from behind shortly after coming to a stop. Some are saying it still exists in the 2005 while others are implying that it has been resolved.
Just to be perfectly clear.... Has experienced this "Clunk" in a 2005 GX?

I have a 2013 GS350 F-Sport. Every so often (maybe once every other week), I'll observe the VSC indicator appear after I slow down to a complete stop, such as at a traffic light. The indicator light remains on while I'm stopped. Once the traffic light turns green and I take my foot from the brake pedal to the accelerator, the car hesitates for a moment, as if trying to figure out how to gain traction, but I then get going, and the VSC light disappears and that's the end of it (usually until it happens again a few days or a couple weeks later). Whenever this happens, the road is flat and dry, so traction should be normal and no problem.
The only other piece of information that might be relevant is that I now believe I can reproduce similar behavior: if I'm at a traffic light, or even just parked, and I simply step down hard on the brake pedal, I observe that the VSC indicator light appears. Perhaps this is simply what is happening in the instances I have observed this when stopping at a traffic light. Still, I don't understand why pressing down on the brake pedal with a little extra pressure when parked would cause the VSC light to appear. Is this normal behavior? Only the VSC light appears in these instances, no other indicators or warnings appear.

Just purchased a 2010 ls with 20,000 miles on it. Brakes make a popping noise when coming to a stop. Not all the time, seem to get worse as brakes get hot. Have had to dealer twice they have resurfaced rotor, bled system put new pads. Still have noise my service manager opened a trouble in the lexus system and called Atlanta. They said this is characteristic of this car. I drove a couple of other ls cars and did not hear the noise. Not sure where this is going to end up. I saw where the brake actuators where changed on the 07,08 and 09.

Looking at a truck at a dealership. 04 F150 Lariat 5.4 3v? 2wd SuperCrew 148k miles. Bone stock besides the bedliner.
Truck is pretty nice besides these 4 things. Kind of a shudder when taking off from a stop or a very slow speed. Adjustable pedals don't work.
New brakes, but possibly the rears are dragging a bit. Was able to turn them in neutral and the rear on jacks. Extra, guessing because of the newer looking battery, some systems lack data from the OBD2
I'm mainly concerned about the shudder from a complete stop/1-2mph. At the dealer, to leave the lot, the driveway was elevated. I think it showed very well climbing that hill. As it was noticed and played with the gas a bit. Otherwise, you stomp the gas, it may shudder for a second or two, (3-5 times?) once it hits about 3000 rpm in 1st, its fine. Only ever seemed to do it in 1st and never any other gear, never on any gear changes.
We lifted the rear end up on a jack and fiddled around. Put it in neutral and spun the wheels, tried to mess with the drive shaft... According to dad, who was looking at it with me said it was fine and that it's normal to have a little bit of slop, but I didn't notice any real slop myself, tried to push on the driveshaft on the transmission side and I think it may have moved a bit but it didn't feel loose or clang or anything. Although I didn't get to push on it too hard because he was rotating the driveshaft at the time.
I assume new fluids in engine and trans. My dad said something about old oil marks on the transmission pan area or something. Both to the fill line.
One thing that I wonder about is how long this truck has been sitting. I wonder about the differential clutches. I'm not that sure what it really has for the rear end. But google had mention of clutch packs in the rear. I wonder if because it's been sitting that the oil has settled out of the clutches or something. There was a mess of silicon on the rear diff cap area. Couldn't tell if it was new or not. I think we put 10-20 miles on it at least and only looked under it for maybe a half hour... Still did the clunk/shudder at a start from a stop, when we returned it.
So, what could be causing this clunk/chatter when talking off from a stop/1-2mph roll?
Axle wrap?
Differential Clutches?
Differential?
Driveshaft?
Transmission?

This spring I installed a Ford OEM limited slip unit in my 05 F 150. Recently I notice a brief, intermittent shudder when turning right or left from a stop sign. Does not do it all the time. I don't notice this any other time. The Valvoline synthetic oil I used said the Ford additive was not needed. Is this the "nature of the beast", should I be concerned, should I put the additive in anyway?

My wife just handed me her 2001 BMW X5(165,000 miles...new engine at 97,000) because they offered only $2000 on a trade-in. It still looks great - better than my Tundra with numerous whiskey blisters delivered by misbehaving cows. The Beemer tires are in good shape BUT the car has developed a loud knocking noise in rear end when you accelerate from a full stop (scares the heck out of you because it sounds like the backend is going to fall off). If you accelerate slowly it doesn't always knock, but other drivers try to run over you. Just had the air levelers repaired. My local mechanic thinks it is the drive shaft but not sure and won't touch it until something breaks or falls off. My question is - if it is the drive shaft and it falls off while driving - is this going to be a dangerous problem? Our mechanic doesn't seem too concerned and just doesn't want to tear it apart to check the noise. If possible (financially) I would like to repair it but will have to drive it to a bigger town to have it done. Or should we just throw in the towel and donate it to NPR?

I am hearing a clicking sound when shifting and perhaps an unrelated but similar click when I am pressing the gas peddle from a stop. Perhaps a CV joint? I'm taking the car in to the dealer (approximately 79,000 km or 48,000 miles) on the 20th to give the car a once over.
