Elantra XD (2001-06) :: Pulsating Vibration Only In 5th Gear At 40 - 45 Mph

In my 2005 elantra GT 5 speed, I get a weird pulsating vibration in 5th gear at 45-50mph. It's noticeable enough to have a friend ask me about it. But it's very slight. I have 124k miles, and a new clutch. I've only had the car for a couple weeks so it's still new to me. My first inclination is axles or a wheel bearing. Maybe a motor mount. But then again, only in 5th?

Prius (2010-12) :: Pulsating Hum And Slight Vibration Coming From Front Of Car

Bought a second hand 2010 prius a couple of months ago. Between about 58 and 68 mph I get a pulsating hum and slight vibration that seems to come from the front of the car. Each pulse lasts about a second then appears again in another second. It's there when going straight and worse if I go round a tight right hand bend and reduces round a left hand bend. If I lift off the accelerator it makes no difference.

Elantra MD (2010-15) :: Pulsating Vibration When Stopped / Jerking Feel

My car gives off a pulsating vibration when I'm stopped (at a light, or in my driveway, for example). Its as if someone with huge bass is sitting next to me, but I'm alone. Its a weird "jerking" feel where I can feel my seat shake like a mini earthquake.

I've tried researching "rough idle" but don't fully understand it. Rough idle implies a clogged intake, which kind of makes sense I guess. I have something better than "my car kinda vibrates when I'm stopped".

Its a 2012 Elantra Limited, all stock everything, 53981 miles.

Golf V R32 :: Pulsating Noise While Accelerating To Merge Onto Highways And Applying Brake

Here's the story, noise first appeared while accelerating to merge onto highways and then applying gentle braking. Sounded like "seagulls". Not my description. To me it sounded like a rubbing pulsating noise. Would not go away unless you came to a full stop. Then would appear again every other time you entered highway at, say, 85 and applied brakes to slow down to 75-80.

The kicker is, that was 35+k miles ago. Annoying, but three different dealerships never found anything and the service techs always made big eyes once you mentioned 85+ mph. "Oh, we can't legally replicate that"

Fast forward to now (meanwhile rotors changed, pads, tires) - the noise seems to appear randomly at lower speeds. It is also quieter (barely noticeable above 65).

Example from today - left dealership sporting new tires and a fresh proper 4-wheel alignment.

After accelerating to ~50 noticed the sound. Couple miles down the road stopped, made a U-turn - sound gone. Could not replicate for a while. Then had it twice on "straight and level" segments, seemingly random. On cruise control at 55 (hear it the best at that speed) sounds stay the same regardless of rpm (6-5-4 gear - no changes). Pulsating gets quicker-slower with speed. Very gently decelerated to 25 - noise went away completely, pedal to the metal back to 60 - no noise.

I'm at a complete loss as for what it can be. Turning makes no impact, no play on bearings (and I'm pretty sure those would have died long ago if it was them), rotors changed with zero impact, tires too.

Changes over time - got quieter and started to appear at lower speeds.

All stock except for H&R Sport springs on stock shocks. 88000 miles

Sonata I45 (YF - 2011+) :: Pulsating Accelerator At 40 To 45 Mph

Got a weird pulsating feeling right through the accelerator when I get to 40 through 45 mph. Tires are new (245/40/18) with approx 2K mikes on them. I guess I have two things to do rotate and balance or just balance. Hope it's nothing to do with the larger tires and messing up something in the car.

Lexus GX 2004-09 :: Pulsating When Warm Up And Braking

05 GX 470...no KDDS...100k miles. When I've been driving a few miles, I feel a pulsating when braking. Feels like it's coming from the front (front left if I had to guess). I put in new rotors and brakes in the front, turned the back rotors and problem still persists, no improvement.

I'm now considering the hub-bearing. However, when I do the standard-check (lift wheel and apply stress from top/bottom) there's no indication of a bad hub bearing.

The problem worsens as I drive faster. When on the highway, if I start to turn the wheel right 'then' brake...the steering wheel pulsates bad. When I turn the wheel left 'then' brake, it's not as bad...but still noticeable. When I start pressing the brake pedal 'then' start to turn the wheel right it's still there but not as bad compared to applying the brake after turning.

There's no pulsation in the break pedal, only the steering wheel and body/chassis.

Ford :: Brakes Malfunction - Pulsating When Braking

I just had new rear drums put on, my front brake pads are new, my rotors are good...but there is still a pulsating when I brake. When I am just about slowed down you can definitely feel a surging coming from somewhere. The steering wheel does not shake, and I don't feel more than a vibration from the brake pedal. I have taken it to 3 mechanics and replacing the drums was given as a solution. But since I have already done that, the problem is obviously not resolved. I know I need new tires as 2 of them are really cupped and loud...could that be it?

Sonata NF (2006-10) :: Humming Noise Pulsating On And Off

I have a 2009 Sonata GLS with about 45,000 miles on it. Lately when I am driving over 50mph it has been making a very annoying, high pitched humming noise. The noise seems to pulsate on and off. If I am going in a straight line, the noise is present, pulsing steadily. If I turn right, the noise speeds up and gets louder. If I turn left, the noise slows down or goes away completely. The noise is not super loud yet, but it is driving me crazy.

I took it into the dealership and they said it was a tire problem - one is worn more than the others (though not so much that it needs to be replaced yet)

From what I have been reading online, it sounds to me like it's a wheel bearing problem, and possibly the worn tire is a symptom of that problem. However I have also read that the average wheel bearing should last about 100,000 miles with proper maintenance. If it is a wheel bearing, it should be covered under warranty, shouldn't it?

Toyota - 4runner :: Pulsating Humming Sound At Around 70 MPH

My 2005 Toyota 4Runner is the V8 version with 4 wheel drive. I'm getting a pulsating humming sound at around 70 MPH - woh woh woh. Thought it might be new tires but it stops the instant you let off the accelerator. Hard to pinpoint location but if I had to guess I'd say driver's side front.

Phaeton :: New Brakes Now Pulsating And Grinding While Braking?

Got new brakes 4 months ago - except this time put in redstuff ceramic pads.

I've had really bad vibration and grinding lately so I just had the rotors machined and cleaned up.

Some of the vibration is gone but when I apply the brakes more than very lightly I get shaking shuddering including the steering wheel. If I apply the brakes harder it goes away.

I would estimate the pulsating/shuddering/shaking happens when I apply the brakes more than 10 percent up to say 40-50 percent. Very light pressure no problems and hard braking no issues.

This has gotten worse since the servicing. What could be causing this? I've already replaced the propshaft and am replacing the tires.

Toyota - Corolla :: Shuddering / Pulsating When Stopped At A Red Light

A few weeks ago on a short drive, my car (2000 Toyota Corolla) started shuddering/pulsating when I was stopped at a red light (and it kept doing that intermittently as I drove the few blocks home.) Next time I tried to start it, it turned over but then died. Towed it to the mechanic, he said it was a dead ignition coil, he replaced the coil and it was able to start again.

Less than a week (and not much driving - 50 miles tops) later, on the highway, it starts shuddering again, feels way underpowered, and the check engine flashes. It's pretty scary. I pull over and have it towed to the mechanic. (It still starts up but doesn't feel safe to drive, plus the check engine light is flashing.) First he says one of the fuel injectors needs to be replaced, then he says that on further testing it was actually another dead ignition coil. He replaces the ignition coil (he didn't end up replacing the fuel injector) and I pick up the car.

It's fine on the drive home (which is about 3 city miles, no highway driving) and on another neighborhood errand, and the check engine light isn't on, but now it's sort of shuddering again. I don't want to keep driving it and/or try it on the highway to wait for it to get worse.

I guess I'll take it in again tomorrow, but does this seem odd at all? I know some people replace all 4 ignition coils at once pre-emptively, but it would seem strange for 3 to fail within ~150 miles (assuming this is yet another ignition coil.) What else might be going on? I had the spark plugs changed last year so those should be fine. The car has pretty low miles on it (about 100k) for the age.

Elantra HD (2006-10) :: Pulsating Humming Noise At 110km/h

I recently bought an used 07 elantra w/ only 34000km (21080 miles), the inspection came up fine but he said I would have to change the timing belt within the next year and he said both set of tires (winter and summer) are on their last season.

Yesterday, I was driving for the first time on the highway with it and I notice a pulsating humming noise at speeds of 110km/h and more (~68mph+). I read that I should try and turn to see if the noise is louder, I will do this tonight.

Could it be the bearing even if the car has only 34k or is it probably the worn tires?

Santa FE SM (2001-06) :: Vibrating / Pulsating After Cold Start

Long time 2004 Santa Fe owner here (LX 3.5 liter):

I have an issue where after a cold start the engines idles a little higher than I'm normally used to. I think it idles at sub-1000 RPM, but now it's more like 1200-1500 RPM. Adding to this it seems to vibrate/throb every 2-3 seconds. It's very slight and unless you've been driving the car for a while you'd probably wouldn't notice the change. I'm used to a steady idling, so this pulsating sensation is new to me. Once I kick it into drive the car is perfectly fine, idles at 500-600 RPM at stop lights, etc., and starting it up after running errands after a few hours in the store yields no problems either. It only happens after a really cold start, say 8 hours or so.

I took it to the shop, all they could find was a slightly under-voltaged battery which they replaced, but the issue still occurs. The only thing I remember doing different around the time frame of when this started happening was add STP Multi-Purpose treatment into the gas tank. I can't imagine a fuel additive having such a dramatic impact though, but who knows.

Accent MC (2006-11) :: Pulsating Brake Pedal When Stopped Only

I'm getting this checked today most likely as it's been happening for months now. No issues with vibration and stopping is fine. As a matter of fact brakes are excellent. However when I'm stopped at a light or whatnot and I depress the brake pedal there's a pulsation that occurs almost every time. It's fairly constant and only happens when I'm at a stop not when I'm stopping so I know it's not a warped rotor. What it might be?

Corolla :: 1996 - Spontaneous Violent Pulsating Brakes

I don't use my car much, and park it on the street. I last drove it 3 weeks ago, and it did great on a 6 hour trip. It is worth noting that until this year, the car had lived in Washington, and this 6 hour trip was the first welt salted road experience the car has ever had.

Today, I go to drive it, and the first time I hit the brakes, I'm greeted by the entire car shaking and the brake pedal pulsating. My first thought was "wow, are the roads really that icy? that's a lot of ABS...". I then realized this was absurd, the roads are clearly dry and this doesn't quite feel like ABS (although it's a very similar feeling at high speeds). My next thought was that I must have ice in the pads, it'll melt off soon. So I drove 20 minutes, and it didn't improve. I turned around, and drove home.

When I first moved the car, I had to give it gas to get it to go and heard a snap. I assume this was it being stuck in ice as I hadn't driven for a while and it was very cold. It could have been something breaking, though.

I have since taken off all the wheels, visually inspected the drum brakes for any damage (pads look fine). I looked at the disc brakes and they looked fine. One of the caliper slide pins was completely seized, so I was hoping that'd fix it, but it had no effect at all.

The brake fluid level is full. I seriously doubt this is warped discs, because it drove perfect last time I used it and it was spontaneously so bad today.

Silverado :: ABS Brakes Pulsating At Low Speed Stops Intermittently

I have a 1999 C2500 Chevy Silverado extended cab. On some slow speed stops the ABS kicks in and makes it hard to come to a full stop scary. There are no leaks in the system. The ABS light has come on, on the dash off and on. I thought I saw a post that you can shut off the ABS system not the real fix but safer until I can figure it out.
