my 2007 Prius has been sounding a bit under the weather lately. There is a grinding scratching noise. This happens in either EV or HV modes and is most noticeable when bearing right. The tires are on their last treads, and a bit scalloped but that seems to me to be a different sound.
View 5 RepliesSo my Nissan Xterra 2006 has started making a weird noise about a week ago. I haven't noticed any problems while driving it but id really like to figure out what's causing the noise. It routinely starts when I start up the car after sitting parked for a while. Example, if I start the car up to go to the store it'll make the noise but after turning the car on and leaving the store I don't hear it. The noise lasts just a little while and is loudest at about 20mph. So once the car is warmed up I don't hear it. I can't really pinpoint where it's coming from because the car has to be in motion driving forward for it to start. It sounds like it's coming from under the car. What it could be.
View 5 RepliesI have a 2009 Gen III T Spirit. Recently, and I think following the recent reflash, I have been getting an extra noise on cold startup. It is a scratching noise that lasts just a couple of seconds about 4 or 5 seconds after pressing the start button. I have tried to attach a short recording but cannot upload an mp3 file so have made it into a zip file.
I have checked whether it is radio by removing fuses 8 and 28 and have also switched off the heater fan, both without any effect.
I have noticed the past months (maybe for a while, probably picked it up just a few weeks ago) when I accelerate, I hear this grinding noise, but once I let go of the gas pedal, and slowly get back on it, the grinding noise goes away. To give a better example, when I step on the gas as I normally do, this grinding noise (it is coming from the front, I feel like it is coming from the passenger side, can't confirm 100%) but once I let go of the gas pedal, it goes away. The noise itself starts when I start picking up speed from a full stop, so when I am going at around 0-30 MPH I hear the noise, after that, I honestly can't tell (road noise may be blocking it off, not sure).
I went around the car and tires, and everything looks fine, I have no error codes thrown at me, thus, I am posting here as I really want to fix this issue as it is really bugging me. (It doesn't impact my drive, but that grinding noise is definitely not the normal sounds of a Prius).
So my dealer diagnosed my 2007 Prius with a transaxle issue, but what bothers me is that it doesn't make the sound all the time. When I brake lightly, there is no sound and when I brake heavily there isn't either. It is only when I do a medium brake above 7 mph of course and around 20's mph range. I am hoping for something besides the transaxle...maybe a wheel bearing...anything.
View 19 RepliesI recently got a prius plugin. In last couple of weeks I have noticed that when I am EV mode and speed crosses over 65, my HV mode kicks in. But I can see the EV mode running in parallel with HV until the EV runs out. During this point, I see both the EV miles and HV miles piling up and it seems like doubling the miles in EV & HV. I saw this four or five times in the last two weeks.
View 19 RepliesI recently lowered my 2015 rc350 f sport awd with tanabe springs. I am hearing the "hinge" noise when i go over small bumps, in all modes.
I think i am hearing it from the left front or rear side. Is this from lowering the car or something wrong with it?
So ive been having a problem with my 2004 Honda Accord. It on occasion doesn't start. I'm talking about once a month I run into this problem. When I do have this problem, I turn the key and it cranks but doesn't start. At the end of the crank I get a scratching noise. My alternator, spark plugs and battery are all fairly new (4 months old) and oem. I'm thinking it's the fuel pump failing.
View 5 RepliesWhat are the selection input for these? I have seen them go back and forward on its own. I have also been told that there is an in-cabin humidity sensor but have seen no documentation on it. Does that switch between fresh and recirculate?
View 2 RepliesIs it "safe" (meaning for the car) to change driving modes while driving? I understand that all it really does is change the way the throttle pedal works but just want to make sure that I don't have to be stopped to change modes.
View 8 RepliesI have had this car for 4 years, and it's been driving, and handling very well overall. Lately, I started hearing a soft scratching noise when accelerating, and especially going from 1st to 2nd, and 2nd to 3rd gear. There was some hesitation before shifting to the higher gear as well. I took the car to a local mechanic, and after test driving, and listening to the engine with a tube??? he told me that he needed to change the torque converter and the pump, and quoted me for $1936. My wife immediately wanted to sell the car and buy a new one. Half of my friends said the same thing (well, at least my richer friends did), and the others said to fix it and drive it while I could do so.
So, I took the car to another transmission specialist, and they told me that the transmission was in great condition, fluids, shifting, etc. Something doesn't add up here. I know that the engine/transmission doesn't sound the same as when I bought the car, but how is it possible to have that kind of diametrically opposite diagnosis. Meanwhile, I took the Mazda to a local dealership, and they quoted me for $4500 trade-in value, while CARMAX said they would give me $2500. Needless to say, I am at a crossroad - we know we have to change the car soon, but how soon and under what circumstances, this is the question. Then, just today, another mechanic said that the engine is unbalanced, and is giving a low, and powerful vibration, and the harmonic balancer needed to be changed.
I just purchased a 2013 Ford Focus hatchback SE Monday night. Tuesday morning I came out of the house to get in my car, I unlocked the car, and opened the door. Before I even got into the car I heard a "scratch scratch scratch whirr whirr" coming from the engine. The dealer did not show me where the hood latch was so by the time I figured out how to open the hood the noise had stopped (within a minute of when it started.) Driving that day I did not notice any more noise, nor any issues with the engine.
Wednesday morning (today) I came out to get in my car, and when I opened the door I heard the same nose coming from under the hood. I got the hood open and looked in with a flashlight while the nose was still going. The noise was coming from the right hand side of the engine block, but I did not see anything actually moving to cause the scratching and whirring noise.
My husband (yes, him not me) drove my car (2009 Subaru Forester) last night and admitted this morning to enjoying driving through numerous puddles. I'm pretty sure it was more of a rally-car type of driving, not the careful-who-knows-what-is-in-this-puddle type. The car wasn't driven since then, until this evening. I backed out of the driveway- no issues. I started to pull forward and there was a horrible screeching noise. I stopped, backed up & pulled forward again- nothing. So I drove to the end of the block, still nothing.
Pulling away from the stop sign- screeching again. My first thought was metal was dragging on the ground- nope. Turned around & went back home, inspected the car- nothing seems loose or out of place. It seems I can get the noise to happen if I accelerate normally from a stopped position, but if I start out very gingerly its okay. It happens between 1500 & 2000 RPMs, the wheels can be straight or turned.
We pulled off the rear passenger wheel (where the noise seemed to come from) and noticed the nut/bolt thing that is in the center of the bolts for the lug nuts (on the break assembly- I think) is damaged. There is a bright blue mark on it and a divot in the metal. This is the only damage we can see. With the wheel on, it is covered by the center of the hub cap.
My car is a manual transmission and the breaks have never been in use when the noise happens. What could cause the noise...
2012 F150, 5.0
Quiet at idle, makes a crinkly, scratching noise under load, becomes almost a rattle or sounds like something is dragging (there isn't anything dragging). I can rev the engine in P and do not get the noise, only when in gear and moving. Quiet when cruising, noise comes on when accelerating. Did not notice the last time I drove it, it sat for a couple of days, then noticed it the next time I drove (yesterday). Took it around the block this morning to see if it was still making the noise, it is.
Obviously, it needs to go to the dealer, but want some info if it's harmful to drive it there, or if I should have it towed.
Last night I took the turn a bit too sharply and the rear passenger wheel drove onto the curb, and I heard a scratching noise from the rear passenger side. Now I'm worried that I've broken something, because now the passenger side leaf spring feels a bit more bouncy than the one on the driver side. I have never paid any attention to my rear suspension until I drove over that curb, so maybe it was always bouncy. What I'm worrying about is the scratching sound when the wheel was on the curb, could that be the traction control kicking in?
View 13 RepliesBought a 2005 FX4 recently, 107k miles, engine and transmission working smooth and quiet. Changed oil in engine, transmission, transfer case and rear axle, filter in engine and transmission, the oil I drained still looked pretty good.
At take-off or when going slowly the truck sometimes makes a really weird creaking/scratching/rattling noise. It appears to come from underneath the truck, I only can hear it when driving close to a building or taking off besides another vehicle with windows down (noise is reflected by building or other vehicle). There is no jerk, the truck drives normal but the noise is really weird (and alarming?). Where to look?
- handbrake = parking brake foot thing - the thing that applies rear wheel brakes when stationary;
- manual = stick-shift etc.
- service brake = normal foot brake/big middle pedal
Driving scenario: Short pauses, quick lights etc - no problem, the car is held on the normal brake and the drive knows I have my foot on the brake so shuts all drive down.
Discussion point here - at lights, longer pause in heavy traffic, level/railway crossing etc. The sort of pause where you want to take your feet off the pedals and wait.
With a manual I would put the car in neutral, apply the handbrake and wait. Then when moving again, car into gear, hand brake off balanced with clutch bite and accelerator.
The car was left in drive all the time & knew if the handbrake was applied not to try and engage forward torque/ride clutches etc. Never needed neutral on the Audi multitronic.
With Prius III when I pull up, if I leave the car in drive and apply the handbrake, then take my foot off the service brake the power modes display shows the car putting torque through the drive train - i.e. battery->motor->wheels & you can feel it pulling slightly in creep mode against the handbrake.
So after figuring out that my 08 is in power mode and will not automatically go back to econo mode ... how can I manually change modes on a GEN II? I know there is a way as I got it in that mode and can't get it out!
View 19 RepliesThis is a true scratching sound...not a buzz or a whine or a squeak. I hear it mainly when the car hasn't been driven for several hours, and it is a constant sound (not intermittent). When I cut the power off, the sound stops immediately. It also eventually stops if I drive long enough (say 30 minutes to an hour). It seems to be coming from the driver's side dash, but I suppose it could be coming from some component under the hood on the driver's side. Of course, my service department is over an hour away and the sound has stopped by the time I get there. They did check for any signs of rodents, but everything was clean. But as I said, the sound stops as soon as the power is cut.
View 1 RepliesI first noticed that the sunroof was making scratching noises when I opened and closed it then finally noticed the plastic on one side had just fallen out. I put it back, but it just eventually falls out again.
5 pictures included. Two show the plastic completely out. The other 3 show how it usually is with most of the plastic in the center attached, but the edges hanging out a bit.

I just had new pads(ceramics, not sure of the brand) all around and new front rotors installed from a local shop that I trust. When braking while cold, there is a grinding sound and feel, I took the car back to the shop, they've acknowledged the issue, double checked their work, and are willing to replace the pads if it continues, which it has. Is there a break in period for ceramics, should I specify a different type of pad.
