Prius (2004-09) :: Faint Jack Hammer Sound From Center Of Car
Oct 13, 2010
I first noted a very faint jack hammer type sound from center of bottom of car last week-noticed it once or twice while driving, but then it continued, a little louder, and even continued when I turned the car off for about 5 minutes. Same thing happened when I drove to work the next day, and when I went to get in my car after work, it was still doing it-I think the noise must have lasted all day. Took it to the dealer and he heard it the night I dropped it off but nothing the next day when warranty inspector came out. The service guy did tell me he captured it on the computer read out and it had something to do with the brakes or ?ABS system. Service said they would drive car home and check it out-he got nothing on his long ride home but the next morning when the car was cold, it reproduced the problem. Inspector was due to come back out next day when car was cold, but came later when it had warmed up and did not reproduce, so will not fix it. They tell me is is safe to drive...is it?? And what the heck could this be?

After 3 months of complaining my wife finally got me in the van to do some errands. We came to a stop at a stop light and I hear this jack hammer noise start, lasts about 3 seconds and trails off. I am looking around the intersection, which is under construction, looking for a jack hammer and my wife says that's the noise that I have been talking about. This noise only occurs when the car is at a standstill after braking and recently happened twice when my wife stopped, released the brake and applied it again. The problem is getting progressively worse.Our mechanic's opinion is that is is a rpm sensor on one of the wheels which is sending a false signal to the ABS system to activate. Another opinion is that the master cylinder has moisture in it and needs to be flushed.This car has about 125m miles. What so I try first?

Has rattle that sounds like it is coming from the centre of the dash? It sounds like a piece of tin sheet metal is rattling faintly. I wouldn't think a fuel line rattle would sounds like that, but maybe I am incorrect? Putting pressure on the dash with your hand doesn't seem to make it stop.
We also get the creek in the l/h side that I had assumed prior that it was from the door seal when the body flexes.

I have determined that I most likely have a bad CV joint - a faint clicking sound while braking that varies with speed that happens with the car in drive, but not in neutral.
I've also found instructions here on how to remove/replace the axle, but I'm wondering if it can be done without separating the tie rod end and removing the ball joint. On other cars I've managed to do this by unbolting the strut, which allowed the hub assembly to flop out enough to be able to slide the axle out of it. Is this possible on the Prius? I have to replace my struts anyway so I was hoping to do it all at once and avoid dealing with potentially frozen suspension components.

2007 Prius with Nav System. Do I need a special cable to use the AUX jack in the arm rest? I have cable I tried to use and I show an AUX connection, but I get no sound out of the system.

I have a 2008. My car has a 12V socket in the centre console, but no auxiliary jack.

2002 F250, 8 inch lift w/ 37's ... Manual locking hubs ...
Ok so my truck has no issues in 2wd even with hubs both locked or when in 4x4 hi/ low with hubs UNLOCKED.
BUT as soon has 4x4 system is in action as I idle forward there's a massive clunking and binding sound like a sledge hammer bouncing off my front diff./ drive shaft. But there's no physical binding of any components that I can see! Just a rhythmic and consistent thumping.
When you turn the wheel either direction the sound intensifies. I even dangled from the side steps as my buddy rolled forward to observe the situation.

Today I drove my 2006 G2 Prius with 59,000 miles to the park and had the windows down. I climbed a hill for a good while that had the engine under load and there was a concrete wall beside me, and I could hear a very very faint metallic-like rattle. I mentioned it to my partner who listened and said he couldn't even hear it, so maybe it is just me.

Last week as I was returning home I had a strange event in my Prius. I was coasting at about 30 mph when I heard a very faint pop sound a bit like a balloon breaking. It sounded like it came from the right rear area of the car. Afterwards I thought I detected a very faint chemical smell. Could this have been something involving the HV battery?

I hear faint rattling from what looks like a center speaker grill on the dash (behind my sensor for DRL) when I press down on it, the noise goes away. What is the purpose of that center grill?

I got into a situation on the expressway last night where I had to floor it from a dead stop and keep it floored. I was reaching about 70 MPH when I heard a faint "pop". The exclamation point came on, the check engine light came on and the car immediately started slowing down. I switched to the screen where it shows if the motor is running and it wasn't. I thought I blew the engine. I got to an exit on battery only and shut it down. Opened the hood and couldn't see anything out of the ordinary and no oil under the car either. Also checked the oil and it was fine.
I got back in, tried it and the motor started but the exclamation point and check engine light are still on. Now I'm scared of it.
It's got 110,000 miles on it and bought it used.

In my 2009 standard prius, the back up camera often, maybe 50% of the time, is just black. It has some scrolling look, and sometimes i can see a faint image of whats there. The warning text on the screen is still there, and I am positive the is plenty of light, and nothing blocking the camera.
Its almost as if the TV rabbit ears need some adjustment. Flickery images, images literally scrolling left to right, etc. Other times, its perfect. Where do i start? loose wires somewhere?

I disabled the backup beeper in my 07. Now I have an ever so slight horn chirp that I hear. There is no consistency to the chirp, but it is a bit bothersome.

My 2010 prius is making a strange sound, and has been since day one.
It makes a "Clicking" sound sometimes that can be heard inside the cabin and sounds like it is coming from the center dash. It is definitely NOT a squeaky dash or door panel or anything like that. It is definitely electrical in nature. It almost sounds like a very fast clicking relay or maybe another electrical component. It is fairly high pitched (not like the inverter whine, though) and definitely clicking (maybe buzzing), not constant. It sort of sounds like a cricket. I am working on adding some audio/video to this post, should have some up today.
Here are some things I have noticed about the noise:
1. Only happens when gas pedal is depressed, not when braking or coasting.
2. When the display is in "Eco" it happens loudest and consistently when the bar is 3/4 of the way full, but it can happen (although the clicking is slower and less consistent) at 1/2 or just before the power section of the bar.
3. The car must be "warmed up" i.e. doesn't happen right away, car must be driven for 10-15 min if engine is cool.
4. Seems to be happening more/more quickly after starting the car in the hotter weather (I purchased my car in Feb.)

At about 20k on my 07 I started hearing a faint whup whup whup between 35 and 50 mph's on the front driver's side area. At 60+ pretty quiet. It has gotten real loud at the present 30K. I suspected the tirers as I know the Integrities are complete junk but as a test I did a rotation and exact same noise.
I thought thats not good but found it hard to believe something else was bad as I had no vibration and no pull whatsoever in steering. Long story short I bought a new set of tires Kumho KR21's at stock size and oh crap exact same noise.

I use an USB drive with my other radios. Is there a way to get an adapter to allow a USB drive to talk to the Prius radio, without going the IPOD route? Don't have an IPOD but plenty of USB's with music...

So today I was doing the 40K mile service on my 2013 Gen3. When I finished I noticed that the front jack point was kind of crushed looking. I don't think I did it this time, but I have no doubt that I'm the one that did it. The question I have is, why is that the recommended jacking point if it crushes like a beer can. I've always used a quality floor jack, so I don't understand. I'm attaching a pic. If there a better place to jack it up from?

My 2007 F150. That jack wobbles in the hole and, when I plug in a cave, it does not make solid contact. What I am wondering is, does that little panel on top of the dash pop out of that hole to give access to the jack? I am wondering if I can tighten it and re-tension the contacts if I can just get behind that panel.

My wife has a 2009 Prius and the center display does not work. At first it was intermittent but now it is off and does not come on at all. We can still control radio & AC through the controls on the steering wheel. I checked the 2 fuses the manual associates with the display(s) and they are both still good.

When Powering off my 2004 Prius, here's what happens: Press Power button, Power button and Dash display(above the sterring wheel) go off, while the MFD screen stays on(center console) - although temperature is no longer reported on the consumption screen, the consumtion screen is still on, power outlets stay on, and clock is still on. Car refuses to lock driver's door, even with keyfob located outside of car. Car beeps as though still on - I disconnect 12V battery to leave vehicle(and not wear down the 12V). Happened for 3-4 days, went away for a week, and its been back for a week since.
Traced problem so far to the three cables behind the 6 CD changer/radio unit. If the middle of the three plugs on the back of the radio/CD player is unplugged, the problem goes away, so does my bluetooth audio. I need to be able to use handfree while driving in my state, also haven't figured out what else is gone when that cable is unplugged. Radio, CD Player, and Navigation still work with sound when that same middle cable is unplugged.

When we were driving our Touareg from the dealer, I (my dad did not notice) noticed that there was a faint whistling sound coming from the car. This happened on surface streets, not freeways, and about 35-40 MPH. Sunroof and windows were closed.
