Lexus LS 2007+ :: Brake Pad Rattle When Going Over Medium-sized Irregularities On Road
May 4, 2015
This question is more for those with aftermarket pads (particularly Akebono pads), how much rattling noise do they make when doing over medium-sized irregularities in the road.
Every time my car goes over a bump it sounds like some bits and pieces of the front suspension will be left behind me. Frankly it sounds embarrassing. Unfortunately, two separate dealers have so far told me that the culprit is the aftermarket set of pads.

I drive a 2012 SE V6 with 1600 km in it. Literally brand new car, two days ago I noticed a faint knock when driving normally over medium sized bumps in the road. Sound seems like it is coming from the front drivers side. It's not my first time around the block and wonder if it's suspension related or steering related. It's going to the dealer tomorrow...

I have a 2006 Kia Rio base sedan. I've owned it from 55K miles to 70.5K miles. It does not have power steering.
When moving at rather slow speeds, maybe 0-15 or so mph, it seems that bumps or potholes or other irregularities will cause the steering wheel to turn significantly. I feel the steering wheel move back and forth by itself and the wheels feel like they "flop" to either direction to the whim of the road's irregularities if that makes sense. The wheel feels almost as if someone is grabbing it and moving it back and forth. The movement is forceful enough that if I'm not holding the wheel, the car can really wander around, possibly into another lane but I have not wanted to test that.
I tried looking up this issue on existing threads but couldn't find it. Also, I didn't really know what to call it. I had an apparently useless alignment at Firestone about a week ago (car still pulls to the right) which did not seem to affect the issue. I attached a scan of the alignment sheet thing.
Incidentally, it seems like they left a thing out of spec but maybe that's a whole other question. So, what could cause this and whether it can lead to damage or safety hazards?

I have a 2007 LS460L. Bought it new and have loved it dearly for 6 years now. It now has 70k miles and is under an extended warranty purchased at 50k miles. As a first year model it has had a ton of TSBs done on it.
The problem i have had as long as i can remember is a lag or stutter during medium to hard acceleration. It feels a little like the old turbo lag or like a very mild stutter. It has had the transmission adjusted, had the service manager driver it for a week to try and capture on computer etc. But nothing has fixed it. At times it feels like if you watch the tachometer during these moments you can actually see a bounce (I may be imagining).
I have almost given up and just lived with it. We have tried tranny, type of oil, software tweaks etc.

I have an annoying rattle the occurs on rough road surfaces. It comes from the front right wheel area but goes away instantly with light brake pedal pressure. Three trips to the shop have not identified the problem. I just read somewhere that there are "anti-rattle clips" or springs on the brake calipers. Is this right and are these the same as the retaining springs/clips that can be seen from the outside through the slots in the alloys wheels?

Problem: rattle between dash and windshield, mostly in cold weather when going over bumps, road expansion joints, etc. Dealer quoted about $1200 to remove dash and reinstall with some new clips. Car is out of warranty.
Parts to fix: 1 piece of craft felt, a square foot of it. Color not important. 50 cents. I clean putty knife that is NOT sharp (a plastic one is great).
Cut: Felt into a few 3 inch wide long strips, then fold lengthwise, in half.
Insert: Felt into area between dash and windshield with putty knife, pushing into the fold, until felt disappears from view (this is why color doesn't matter)
Drive: the car a bit to see if you fixed it. If not, put another strip next to the one you did, or another one on top of the one you just did.
Worked for me. Clean, cannot see the felt, easy.

I have an 09. I heard a rattle on a rough road and crawled underneath the engine. The right front skid plate bolt is missing. What size bolt belongs there.

I got my all new Lexus but driver door has been rattle since 400 mile. It's like plastic vibrating and creaking.... I think it's the door panel is making the noise especially on rough road. When it rattles, I can place my hands on and share the vibration, then the noise would be somehow suppressed.
The problem is that I took it to dealer and they, as usual, cannot reproduce the problem! I took down the door panel myself, tightened all screws...and the noise...got worse....

In the last few months my car has been making this crazy medium-weight rattle sometimes, meaning it doesn't sound like something really light doing it and it doesn't sound like something heavy doing it either. Its "history" went like this:
Noticed this sound that really seemed to be coming from the driver-side front, in the wheel well area, checked it out. Nothing obvious. Had the front of the car on ramps a couple of times, poking, prodding, grabbing/shaking things. All is tight. Then had it on stands; same routine, same results. It got a bit worse over time, though it doesn't ALWAYS do it! Sometimes it's quiet forever (on 90-minute drive last week, nothing). This evening, out for 20 minutes, lotsa racket. So it comes and goes. Nothing under the hood seems amiss, either.
At first it seemed to only be present when moving, like something rubbing or dragging on a tire. Nope. Then it seemed to be related to engine speed, like some under-hood component checking out and starting to fuss. That seems not to be the case anymore, either. Now, I've been able to discern that it's something come loose and VIBRATING (I'm pretty sure -- it just sounds like that), but I don't know what yet. I now hear it at idle, sitting at a light (sometimes) and it's definitely worse on rougher pavement than on smoother pavement.
A while back I realized that it must not be coming from outside and under the car after all, because putting the window/s down results in not being able to hear it at all, rather than being able to hear it better. This is true even at 5 mph, rolling along on a quiet street entirely for diagnostic purposes.
Earlier this evening (during the 20-minute out n' about), I note that it's not coming from the driver side anymore; it's more like the whole front of the car. Really seems to be under the dash. When I first figured out that it's NOT outside/underneath, I took off the panel under that side (three Torx screws) and poked around. Didn't find anything obviously loose, etc. I've ruled out the glovebox, its door, and the center console, by holding on to each while rolling. The sound is not quite in the correct spot to be from any of these, either.

I have been getting some knocking the under most any loads . I do not have any codes. I tried premium gas and that did not make any difference. If this is not fixed what issues can this cause? What should I look for do get this fixed?

I noticed that driving my LS last weekend that the right headlight was fluttering going down the road. It did not go off but it looked like a loose connection. When I arrived at the golf course, someone told me that he noticed that the right headlight was out. Now I got home and I have checked the headlight and nothing seams to be a problem. Both low beam and high beams go off and on with no problem. My question is : is the headlight bulb going out or do I have a connection problem? I hate to take off the tire and inner wheel cover to change the bulb unless I need to. Second question: If I have to change the bulb what is the best brand to use?

Car still vibrates between 65 on up. However it is intermittent. Sometimes it will vibrate at 70. Sometimes smooth as silk.
I got the car road force balanced all wheels are between 6-7 lbs. I am going to go to the shop have them lift it up and check the lower ball joints and all the control arms.
QUESTION: Can I just replace a ball joint or do i have to replace the entire arm? Is the ball joint connected to the control arm in any way?

I have recently run through a large pool of water on the road and this shortly after tuned on the engine warning light and the " ! " light. Everything seems to feel Ok but had the OBD code read and it shows P0051 and also showed VSC. What to look for?

So my wifes 07 93k miles started to make a strange knock rattle noise. It sounds like the knock some on here have when the water pump was going out. It only happens when the car is on, in gear ( drive or reverse) brake pressed And AC ON. The engine begins to vibrate under the load and the rattle begins. Sounds like you its coming from behind the alternator under the valve cover. Once I place it park.... or turn the AC off it goes away. It idles fine. Quiet And Smooth. But once I place it year it comes back!!

I can be driving down the road and "blam", the "check parking assist" comes on my nav screen. This message screen comes on and goes off all the time. It comes on when I am not around anything close. I had the parking assist sensors checked and every thing checked out OK. Could this a an electrical problem? If it becomes irritating, I just turn the parking assist off.
