Prius (2004-09) :: Subtle Thump When Coming To A Stop?
Feb 27, 2012
I'm not even a Prius owner yet but have test driven 5 used ones in the last few days. The thing that is bugging me is a very subtle thump when coming to a stop. I noticed it on an 06 with 77k mi and also an 08 with 45k. I am more curious about the 08 as it was more noticeable and I drove the car quite a bit trying to figure out the sound, when I would slow down from about 35mph just as the car was at 3mph just before coming to a complete stop(and coming to a normal/gentle stop, not jamming on the brakes), there is a little thump. To me it sounds like possibly one of the electrical motors is stopping it's rotation and causing it, or maybe the braking system. When I abruptly stopped it would not occur. When I would slow from just 15mph to a stop I did not notice it. The 06 with 77k almost seemed like it would make the same sound but do it two or three times while gently braking and much more subtle than the 08.

Hear a thump when slowing down or coming to complete stop? Thump doesn't happen every time but sounds louder sometimes and doesn't always seem to be in the same area of the ceiling.

I am having a very intermittent thump/bang/slip in my front end when coming off the highway or taking off at a stop. Believe it or not this is when i drive the car perfectly normal and don't stomp on it which I haven't done much with this car.
I was under the car the other day and noticed neither the dogbone mount bolts looked to have been replaced and i saw the back subframe bolts look to be moving around due to rubbing marks on the subframe.
Car has been in three times to seacoast volkswagen this last time the tech drove with me and they wont do anything because they cant replicate the problem.
I noticed its between 4 to 3rd down shift and 1st to 2nd up shift that it happens so far. It is LOUD and extremely noticeable and feels almost like a slip and heavy bang.

2004 Explorer XLT, 4wd, 60k on the odometer, brake pads and rotors replaced about a year ago. When coming to a stop, usually a harder stop, Im getting a resounding "thump" in the floor. I can also definitely feel it in the brake pedal. Its like something is binding up and then letting go. Seems to be coming from mid-vehicle. What this could be?

My 2004 camry LE (235K miles) has had a noise associated with the blower for several months. The blower worked fine on all settings but had a subtle noise that was between a purr and a click. It's constant, fast-paced, rhythmic and rises in pitch as the blower setting is changed. Hot or cold settings don't make a difference. The closest I can approximate is the sound made when kids put (or used to put) playing cards in the spokes of their bikes.
However in the last couple months the blower has stopped working intermittently. Sometimes it will come back on if I went over some railroad tracks or a hard bump. If I turn the car off the blower may not work when it's restarted. The last couple days it's stopped doing even that, and since there's snow on the ground it has become an issue! The fan setting doesn't make a difference, high or low.

Am a recent owner of an '06 Prius and like the car so far. The only fault is something I have never run into before. The brakes are very sensitive when coming to a stop. I find it almost impossible to feather the pedal and make the stop comfortable.

I purchased a used 2010 Toyota Corolla LE with about 40k miles back in February of this year. Since then, the car has been issue-free and has responded accordingly.
Two weeks ago I noticed that the car when idle or at a stop light it'd make a subtle rattling noise (as if it was something behind the glove compartments rattling against metal). At 1st I thought maybe it was something inside, but as that week turned to days, I noticed that while I was outside the car and it was on and idle, I could hear the rattling from the right side of the car under the passenger seat (closer to the engine, as if right below where the glove compartment sat)--It is a constant rattle at the same frequency..meaning it doesn't rattle one way 1st and then another later. It sounds the same, but it is random.
It evolved from a subtle rattle inside to being a loud rattle outside under the car. I noticed that if it was rattling and I turned off the air, the rattling would stop, but after 20 seconds, the rattling would return just not as frequent.
It was advised to me that perhaps it was the blower...but the blower sits behind the glove compartment and should not sound so loud under the car. Not only that, but if the blower isn't on (when I turn off the air) it shouldn't sound...at least that's my logic for it.
The sound is getting louder and more frequent at this time and I'm just not sure what to do about this. I live in Miami, FL and hearing so many rip offs at mechanics, I don't know what this rattling is and I've already crawled under the car and see nothing wrong, nothing shaking violently, nothing.

Hit a MASSIVE pothole this PM at about 80mph... Car felt 'different' almost immediately. A subtle vibration coming from the steering wheel... which could also be felt on the dash, but ever so slightly. As if something was 'out of round'- OR is I had a bad bearing.
Pulled over at a gas station, but I saw nothing wrong with the tire or wheel. Was very surprised by this as I thought for sure I had a bet wheel or a bubbled tire. Only thing loose was the center cap.
Making an appointment this week at a dealer to check things out. Hoping it is just the bent wheel, busted tire, or wheel alignment issue... but thinking its more than that possibly.
What should I be asking the dealer to check for me? Control arm, drive shaft, strut, bearings... anything else?? I would hate to get the car back with the same vibration, and have them tell me 'all is Ok, we see nothing wrong'.

A few days ago I was driving on the freeway for about 20 minutes and started hearing a subtle whining sound coming somewhere from outside the car. To quickly narrow it down to the engine, a wheel or the drive train, I pushed the clutch in, took it out of 5th and waited for the RPMs to drop. Then I hit some noisy rough asphalt and couldn't tell. Oh, well.
Here's the first big clue. When I shifted back into 5th, the gear shifter went into gear with no problem, but the clutch would not re-engage despite the pedal returning to its normal position.
Here's the second clue. Since I couldn't get the clutch to re-engage I decided to try one more data-gathering action. I turned the engine off (still coasting at 70 mph) and tried to restart. It would not restart, exactly as if I had not depressed the clutch pedal. So, I coasted for as long as I could and then walked the remaining 1.5 miles.
Here's the third clue. When I got back to my car about an hour later I tried to start it again. No joy, but then I heard a click underneath the car when I released the clutch pedal. I tried once again and it started. I drove the remaining 1.5 miles to the exit and started to notice the clutch appearing to stick for a second and then suddenly release. When I got to the gas station where I was before, it was done, just like on the freeway. Again, the gear shifter and the clutch pedal operated totally fine, but it seemed that the business end of the clutch would not re-engage until it cooled off. After it cools off, everything seems to work just fine.
So:
1999 Explorer Sport
4L V6 SOHV
5-speed manual
196,000 miles
What should I check?

My 2008 Prius has approximately 116,000 miles on it, about 8,000 miles ago, I put on a Mobil 1 Extended Performance filter and 5W 30 Mobil 1 Extended Performance Full Synthetic Oil. Over the past week, My "Exclamation Point Triangle Light" (Not sure what it's called) has flashed a couple of times when coming to a sudden stop and the car would emit a "beep".
My first assumption was low brake fluid, but today when I got home and checked the fluids, I found the oil to be approximately 1.5 quarts low... I have not noticed any leaks under the car (I park in the same spot at work daily), and haven't noticed any smoke coming from the rear...
What the problem might be? Is it possible I might have damaged the engine by driving on such low oil for an unknown period of time (guessing a couple of weeks or so)? I used to religiously check the oil in all my vehicles, but have gotten out of the habit on later model vehicles...

So yesterday afternoon I went outside and started my truck up. Upon starting it up and flipping the AC to high I noticed a clicking sound coming from somewhere inside my dashboard. It did not change in rhythm regardless of what setting the blower was on. But it remained for a couple of minutes before it subsided.
For the record it wasn't a subtle clicking...It was a very obvious sound. After the noise went away I continued to use the AC and it worked just fine like it always has. What it could have been? 2011 F-150

My nice little 2002 GL 1.6 has 160K+ on it. Lately, when I come to a stop, I get a thump when she downshifts. I don't know which gear exactly, but it happens when the car reaches 10 MPH and below, so maybe when it goes into first? It is just as the car stops, it seems.
More recently, it seems as if when I get just about stopped, it feels as if she completely disengages from drive and goes into neutral. But it doesn't actually do that, she is fine when I take off. She upshifts just fine, it's just that last little bit when coming to a stop.
I have never had the transmission messed with very much, but I know it was serviced a few years ago. I did add a little fluid a few weeks ago after I checked it, and I was very careful to purchase the exact correct fluid.

I just upgraded from an '08 GTI to an '08 R32. When I start my R, I get this subtle whining noise which seems to be coming from underneath the passenger side of the car. I stuck my head under the car to try and determine where it is coming from exactly, but I couldn't really tell. It's not a loud noise, but I hear it whenever the car is running. I did a search for it, but I couldn't find any posts describing this particular noise.

I recognize the odds of isolating this is low, but thought I'd try. I have been hearing a a very subtle (but noticeable) noise coming from within the dash area of my 2002 Passat (mostly near the glove box side, but also in the middle area). Noise occurs when the ignition is turned on - with or with out the engine running. It can be heard while driving, but is more noticeable when I turn the HVAC fan to off. The sound is random, and seems to be like a relay dithering, an intermittent buzzer or a fan noise (although no fan is on.) It sort of sounds like a cell phone vibrating randomly in the glove box.

Sometimes, when I take off from a red light or stop sign, my car makes a thump. This feels as if it is under the car, not a transmission shift noise. It would seem to me that it has to do with exhaust or fuel???? I am guessing.

For probably years, I have had a bump, thump type noise when I start from a dead stop... say at a red light. I had it in my head, maybe there was that much slop in the drive train... as old truck is over 400,000 miles.
Yesterday, I rebuilt the driver's side axle, bearing,seals, new hub...the works.. I heard that noise again later... and my thoughts were, I did all that work and I'm going to find a lower/upper ball joint is bad, although I did look at them and thought they were fine during the rebuild.
Had my wife get in truck.... and swing wheel back & forth... so maybe I could see what was loose.. or making noise.
I was shocked... just something I never thought of looking at. The u-bolts holding the leaf springs were loose... the whole axle was shifting back and forth on the axle. I've never touched those bolts....

The other day, I was coming home from work. After dropping off co worker, an old man pulled out infront of me. I applied the brakes. As car came to stop I heard a loud thump come from rear. Sounded like i was either bumped by a car, or maybe my entire rear end slid up 5 inches. But that's kinda what it was like. Then after the thump, I put my foot on gas pedal, and instead of car moving forward, the engine just revved. No movement, revved to like 3 grand. I let foot off gas pedal. And tried again. Car moved as normal. Then on the way home i attempted the same combo of rather quick brake and then gas. Same kinda thing happened. Not so hard of a thump. But noise from rear followed by the car no moving, just revving up till i stop and then try again. So even tho my story may suck n my explanation my suck more, whats going on? I just picked this wagon up. 01 glx 65k.

Just bought certified preowned 2009 Prius from dealer. Never had one before. I did test drive it for 20 minutes before purchase. But on the way home from buying it today I noticed a constant and subtle "stammer," on the freeway at speeds between 50 and 80 mph, like as if the car was very slightly and frequently shifting in speed even though the accelerator was in a constant spot and the road was flat. I watched as the display constantly shifted, like many many times per minute, where and how power was being generated/used.

Bought a brand new 2012 Prius in California - Power Toyota in Irvine. It was heavily raining so did not test drive. Package 3.Next day noticed that there was excessive road feel and buzzing like vibration.Took the car in and they noticed it too.
Changed Goodyears to Yokohoma, checked suspension and tire pressure. Issue did not go away. It is subtle but constant. Dealership said there is nothing wrong with the car and every car drives differently. Offered to change car with me taking a hit of 5000 dollars. It is like driving on a stone like rough surface with a buzz like vibration.Other cars I test drove did not have this. Two of my friends have 10 and 11 Prius they did not have the problem. They also felt the Buzz/Vibration in my car.
