This is a 2001 Prius - car runs great and the AC is fine. However, driving down the road, when the AC is turned on there is a noticeable scraping/ticking noise - sounds like it coming from under the hood.
With the car parked, and the ignition ON, but without the gas engine running, there is no scraping noise.
2001 Ford Focus ZTS manual. Squeaking/scraping is the best that I can describe it, happens sometimes while driving maybe 20 mph. Also makes a rapid clicking noise when starting from a stop, groaning noise with engine on/off while turning wheel from same area. I did pads/rotors last year. I had play in the wheel, axle nut was loose, tightened and went away. I can't find any problems. It can make some noises under heavy braking and it was making noise from moderate braking, I'm guessing that's my cheap rotors.
View 2 RepliesAbout 3 weeks ago, I noticed the SUV would occasional make a loud "CLICK" sound in the front steering area, usually if I made a fast turn motion (either left or right).
So today I put it up on a ramp and took a look and it's obvious there's a part in there that is coming loose. I don't know what the names of the stuff is in there, so I'm posting a photo with arrows & letters so people can tell me what's what, and also what to do.
I tried putting a vise grip on it and tightening it with a ratchet wrench on the top part (16mm), but the lower nut just spins. I decided to not go any further because I really don't know what that assembly is, what it does, if it's broke, etc.
When I was at about 40k miles I started to have this problem. Driving above 35mph the road noise started to get louder. I first thought it was my tires but the noise went away after driving about 1k miles. Now I'm at 72k miles on different set of tires and the noise is even louder. According to a few mechanic shops, they say that there is not enough air flow going into the engine. But I'm not sure if that's the problem. It's not under warranty anymore and I can't just take it to the dealer to find out what's wrong.
View 14 RepliesI noticed coming home from work that my 2010 prius is making a scraping noise as I drive. I don't have far to drive and i drove slow but I did notice it. I see the rim of the wheel is scraped and the tire is too like it got hit somehow.
I can't seem to figure out what is causing it and i'm afraid to drive it anywhere because the nearest toyota dealership is about 20 miles away via highway.
Its like part of something is scraping as the wheel goes around. its not a constant scraping. That and I notice the steering wheel is pulling to the right.
My 2004 elantra shuts off while driving, while making a machine gun noise. If I try to start it, it will continue making the noise. I wait a few minutes after clicking and whirring robot noises stop and then it starts again. I've tried the cam position sensor, that worked for a few weeks but it's doing it again. Luckily it seems to only happen at slow speeds, before I pull into traffic.
View 5 RepliesI got in the car today and started it... I was waiting a few seconds for someone to get in the car (it was in the garage) and as soon as the engine kicked on there was a very very large long rattle noise i immediately turned the car off. Waited again and turned it on same noise.. the only thing I found was a cover under the car towards the front was really loose. ( I haven't hit bottom or anything while driving) but I did have the lighted door sills just installed the other day. But it never made that noise..
btw i have 1100 miles on it..I looked under it and is the black dust protector thing supposed to be loose like if I push on it I can make it rattle..
Starts getting loud above 35mph, local tire shop recommends replacing the struts- says they are causing bumps in the tire because the tire is bouncing along as I drive. I did feel bumps going across the tire when I passed my hand across it.
View 15 RepliesThis just recently started happening just shy of 200k miles, 14 years. While driving down the road, suddenly notice a power loss or no power, i.e., no motor output. Sometimes the just the ICE won't accelerate, sometimes it's both ICE and Electric motive force. When this occurs, the Brake and ABS check lights turn on. After a few seconds, to 10's of seconds, then the motive power reenables and the Brake/ABS lights go out. Often the cars continues on with no repeat. Testing over a few drives, it seemed to only do it during the warmup cycle when coolant was near 160-170.
However on a drive in the afternoon after it occurred in the morning; with ambient around 30 degrees, windows cracked, interior heat off, it didn't occur on the 15 minute drive, mostly freeway speed, even after about 10 minutes and cranking interior heat on. No codes are registered when this happens. I used Torque Pro and monitored things like throttle position and such, and things there seemed normal. Eng rpm dropped under 1000rpm and wasn't steady. Watching the MFG the power flows responded to the throttle (pushed/released) as if the engine was still doing what was asked (go figure, the display shows what is commanded, not what is occurring?).
My 2012 RX350 now for over a year and like it a lot.........BUT.
There's seems to be a lot "road noise" that's transmitted back into the cabin, like driving over expansion joints on blacktop or rough road surface, is this normal?
I drove a 2000 RX300 for 100,000 miles and don't remember it being this noisy. Interior noise is great and quiet.
I just bought this camry recently, it's an 2008 SE 4-cylinder with about 95k on it. Everything is fine on the car with the exception of one thing. Whenever I start it after a prolonged period of it being off, say in the morning or sometimes even having it off for an hour and then starting it again, when I start it, a loud grinding/scrapping noise comes from the front of the car.
This noise lasts for a good 30-60 seconds and as the car picks up speed it disappears. It just happens whenever I start it. Now I'm not sure that if the brakes or jammed or is it something to do with the transmission. I mention the transmission because during the drive, the car seems under a lot of pressure as if towing a large trailer and has trouble accelerating. At times when going downhill, it actually is slowing down as opposed to picking up speed and as soon as I let off the gas the speed drop from significantly.
I know this isn't normal because I used to an 2005 Camry LE 4-cylinder. So I know how the engine and transmission behave.
I took it the dealer recommended mechanic and he said that everything is fine. He's a nincompoop really. I took it to my mechanic and he said that the axle and bearing need to be changed on the passenger side and just the axle on the drivers side. My mechanic is a family friend and is skilled in his trade so I know he's not trying to shaft me.
I have bought this car in 2006 and had a trouble free experience so far. My car had roughly 170000 Km on it. This very first generation Prius from Japan and all the instruction is in Japanese. Engine: 1NZ-FXE
Main Problem: At times when the turtle sign comes, the engines makes a lot of noise. It feels like the engine is overworking. I also hear some air suction kind of sound from the back of the car (I believe it is to do with the main battery). The car will not accelerate. I need to go to the road side and then turn off the car. Wait for a little while (may be 5 minutes). Turn the engine on and then drive again.
Other problem:
1. Red Triangle is always on (see the pic)
2. Dash Board screen is always and now completely white so I cannot see any error message (see the pic)
I noticed when driving on a rough surface/road (gravel, snowy road with sand) the there is a considerable amount of noise coming inside the cabin on the rear end especially.
When I was doing a quick wash today I just realized the sound is coming from the wheel base. On the rear and front end there is a plastic covering the wheel base. Sound proofing / undercoating wheel base.
I just got a 2007 Prius and using it mostly on a dirt/rough road. My problem is that there is a metal cranking noise coming from under car and trunk. This is nit happened when i drive on a good road.
I already asked the mechanic to check sway bar, shocks, struts, and brake. They said everything is okay except the front left strut boots which is already worn out. But the strut itself is still in good condition.
I'm OK everything except the noise. Already replaced new tires but it doesn't work....
I have a 2002 Mazda tribute, and I was driving down the road yesterday when I heard a loud pop. After, the check engine light started blinking, the lights and electricity started struggling, and I hear a loud thwack thwack thwack sound when I step on the gas. This sound gets louder and faster the more I hit the gas. When I checked under the hood, the serpentine belt looks fine, and there is no visible damages but when the car is running it sounds like I have no exhaust system it is so loud.
What could have happened and where I should start working? Family and friends have thrown out a few things but I do not want to start taking things apart if If they are not the problem.
From the time I start the car till I shut her down I hear this loud screech. I thought belts but they are not the cause! 2001 elantra 5 speed transmission ...
View 3 RepliesOK so - I had the rear axle bearings replaced, but I'm still hearing a rotational scraping noise while moving (whether gas is applied or not, or whether braking is applied). Gets slightly louder the faster I go. But when I turn, the noise goes away. It's hard to pinpoint where the noise is coming from. My wife swears it's in the front; to me it sounds like it's in the middle (so it would be being transmitted from the source).
I took it back to our mechanic, but he can't hear it very well - he admits that his hearing is not what it used to be (he's in his 70s). Only thing he hears is "gear noise in the rear"... meaning he'd have to replace the differential in the back which would be prohibitively expensive and not worth it. He said I should come back in a couple weeks when his younger employee will be back so he can listen for it.
My 2001 VW New Beetle has started making a loud, whining noise coming from outside the car along w/ some buzzing whenever I am driving. I find that I have to change gears about 10 miles sooner than I should in order to stop the noise. But now it's happening in 5th gear occasionally too, and of course I can't go to a higher gear to make it shut up. What could this mean?

View 19 RepliesReplaced my rotors today. When I was done, I spun each wheel to see if there was interference. Passenger wheel spins freely. Driver's wheel makes a scraping sound (brake pads?) and stops pretty quickly.Which one is wrong or bad?

my '06 Honda CRV makes a short scraping sound when turning. But more interestingly, it only makes this sound when the car has just been started. If I've been driving, the sound will not occur. The sound itself is a short scrape which seems to originate in the rear passenger side of the vehicle. I've researched this problem a bit, but everything I've turned up is related to the AWD model, while my CRV is 2WD. Just had the brakes serviced and checked, so that's out as well.
