Lexus IS 2014+ :: Car Makes A Slight Thumping Noise When Brake
Feb 10, 2015
i drove my car for the first time in a few weeks and i noticed when i brake my car makes a slight thumping noise and has a slight vibration. i looked at my brakes and they look fine, they are brand new, less then 5k miles on them.
i thought it was maybe i haven't driven them a while and it was from a rust and dirt built up, but its not.
not sure what it might be, tried to record a video but it didn't come out all that great.

IS F Sports (2014), Clunking/thumping noise when you go over a bump. This is a known problem throughout the IS F Sport series.

I have a 2014 IS 250 F Sport and in less than 500 miles, the car has this "LOUD" clunking/thumping noise coming from the rear when I pass a bump or uneven road. Brought it back to the dealership but the Lexus specialist/technicians said this noise is the characteristic of the vehicle which of course it cannot be a characteristic of the vehicle. This is not the 1st Lexus vehicle I own.
Also, navigation/radio shuts off while the car is in motion? Dashboard just turns dark (completely blackout) while the car is in motion??

Our 2013 RX350 has a brake pedal that makes a pretty loud noise when it snaps back after you depress it a little harder and take your foot off. I complained to my SA, and they told me it's normal. It's not a big deal, but any other car I have owned, I have never noticed such a thing.

When driving in any direction, my left front wheel makes a thumping noise. it's not the tires, i have brand new ones. i can feel the thumping in my gas pedal, and if i were to let go of the steering wheel, the car moves to the left really hard. i have had people tell me wheel bearings, and i have had people tell me warped rotor.

When driving I hear, not feel, a slight thumping noise that if I had to guess would say is coming from the passenger side front. When I let off the gas the noise becmes more prominent and you can feel the thumping. Also when I apply the brakes heavily the sound/feel goes back to the same as if I was driving. I'm thinking CV joint/axles or spindle bearings, but I cant understand why the condition is at it's worst when I'm coasting. Has this "noise while coasting" problem.

Just received my car back from the service department and noticed a slight clicking sound that isn't too loud, it's mechanical sounding.. Quieter than a ball point pen retracting I'd say. It clicks every quarter of a turn while stopped and low speeds.

Noticed a slight whining, fluttering-like noise when accelerating? Faint but it has an annoying tone. Seems to come from driver side but not sure it can't be heard on passenger.

So I'm new to the all time awd car thing. I came from a 4x4 truck which 4x4 was never engaged on pavement or in tight cornering. When maneuvering my is250 awd in tight spots ie. parking lots and the front wheels are at full lock in either forward or reverse there is a slight binding/grinding feeling or faint noise. Is this normal on an awd car or Lexus specific??? Did a quick search and didn't find much about this issue. I'm pretty sure its not tire rub.....stock set up.

Just purchased a used 2008 prius with 80,000 miles on it. Braking system makes slight grinding noises when getting below around 10mph. I know the brakes are different, so I'm not sure if this is normal or if it means my brake pads need replacing? Car didn't come with an owners manual .

For those with a sunroof do you have the same issue as me?
On the passenger side when I apply slight pressure to the headliner, I get the following noise. In person it sounds like plastic tubes knocking around. The driver's side does not do this.

When I go over a medium sized bump at moderate speeds, there is a loud thump coming from the trunk area. My trunk is empty and everything looks fastened down securely. The only thing I notice when I check the trunk, If I hit the center of the floor board, it imitates the sound almost identically. I checked the spare tire... everything.. In my trunk is the floorboard and the lexus carpeted mat.

I have a 2002 Toyota Sienna van. My garage failed to check the brake shoes as requested, so I gouged the back brake drums and had to have them replaced. Shortly afterwards, whenever I brake, in the last 2-3 seconds before I stop there is a thumping noise from the right rear wheel. It will thump a few times, maybe 2-5 times, perhaps one thump per wheel rotation. I don't feel any pulsing in the brake pedal, and except for the noise braking seems normal. Could this be due to the shoe adjustment being too loose, so the shoe has room to pulse inside the drum?

I am in the process of replacing the front hub seals so my ESOF works again. I tested both front hubs with a mityvac and neither one of them holds any vacuum at all. All the lines are good, and the pump and solenoid seem to be working fine.
I have the driver's side apart and I have a couple of questions.
What's a good source for the vacuum seal? I've checked rockauto, riff raff, and diesel o-rings. Diesel o-rings has it, but the description says it's only for 2003+ Excursions so I didn't order it.
There is no yellow o-ring anywhere on the hub. I assume that someone forgot to put this o-ring back in and this is why I don't have ESOF? I guess what I really want to know is that there isn't some 2000-specific thing where there's no o-ring, right?
After I got the hub off, I spun it around on my workbench and it doesn't sound good at all. It makes a slight metallic grinding noise about 1/2 way around. I assume this isn't normal? AFAIK these are all original parts - but the missing o-ring means to me that someone already had it apart.
There was a lot of water intrusion and rusty colored grease but nothing was dry, the needle bearings were intact and the shaft isn't scored at all where the bearing rides. I'm hoping new seals and good cleaning and it should be good as new. And then it's off to the next side.

Lately my cars been shaking pretty bad and making a thumping noise when i have the brake pedal about halfway down. Doesn't seem good. What it could be? also it makes a pretty loud whining type noise when the cars on think its a pulley or water pump but not too sure.

My local dealer had a special on an oil change, tire rotations, and break inspection and my 2011 Elantra GLS auto w/ 20k miles was due so I took it in.
After I got it back I noticed a noise I had never heard before when reaching speeds above 45mph. The best word to describe it would be "thumping".
I figured maybe due to the rotation the tires might need to settle in, but I've drove about 50 miles since getting it back and the noise isn't even slightly going away.
The worse part is my avg. MPG went from easily/consistently being 40+ down to low 38/high 37.
Should I just give it some more time or start to worry the service guys messed something up? Until today it's been the perfect car.

@ 45k miles.
1) Loud brake squeal left front on very light pressure. Pads have 75% left.
2) Vibrating/thumping noise up front above 80mph. Does not sound mechanical and not felt through the wheel at all. Seems like a loose piece of trim flapping. Wheel well liners and plastic pan under car seem tight. And no, driving under 80 is not an option.
VAG quality FTW!

On our 2008 Prius, while the brake assist pump is running I get a steady thump-thump-thump-thump noise, as shown in the video below. If you put your foot on the brake the noise stops. The brakes operate fine and there are no warning lights on. What this might be? It's coming from the passenger side of the car, and oddly it's loudest under the car near the back seat. 86,000 miles on the car.

Just picked up a new 2014 rx fsport and 75% of the time I release the e-brake it has a loud clunk as if metal smashing metal. I tried releasing it really slow and it still does the same. The vehicle is parked on flat pavement. It is not a low click noise that I am used to but a loud clunk.
