Prius (Gen 3) :: 2011 Versus 2014 - Increasing Engine Noise / Vibration And Drone At Higher RPM
Well Prii have always been a little "loud" under acceleration due to the CVT and small engine and minimal sound proofing, BUT We have 2 Priuses (Prii??), a 2011 with 41000 miles and a 2014 with 7k miles. My daughter got the 2011 to take to college. 1200 mile round trip so it made sense.
She maintains that for sometime, the 2011 is making more of the droning/roaring sound that a Prius makes when accelerating briskly. I did not really believe, her, but over holiday break, I had the opportunity to drive both cars more, and she is right.
The 2011 is clearly louder under acceleration. It also will develop a bit of a vibration at certain RPMs, even at very low RPM sometimes, when the economy bar is just beyond the electric mode.
The noise differential between 2011 and 2014 is most apparent at cold temperatures, but it does not resolve completely even with both engines fully warmed up.
Prius (Gen 3) :: Econ Mode At Higher Speeds?
I just bought my new 2010 Prius the day before I went on a 300 mile trip out of state. Dealer showed me the eco mode, which sounded like a good idea to me. Drove on the expressway, about 70 mph, decided lots of power was not necessary and I wanted the best mpg so I put the car in Eco mode. Drove great for about 250 miles, then all of a sudden, I began to lose power. Fortunately, I was nearing a rest park. Pulled in, was there long enough to take care a Rest Park business, started back up and car ran fine. BUT I did not use Eco mode. Question: When should I use this mode and when should I not?

We have had the 2014 Camry SE for 3 months, 2000 miles, (we also have a 2005 Camry LE) and our first interstate trip is when we noticed it. When we get close to 70 mph and above we hear it. Sounds like some maybe flapping/rubbing? No really metal sounding, maybe plastic? I have checked under the car, do not see anything loose. We first thought it was coming from the storage area in between the seat, but we took everything out and the noise continued. Dead center under the car it sounds like. It does it every time, the same sound.
View 11 RepliesSC/SL/SW :: 1999 Saturn SL2 - Noise From Right Side Wheel At Higher Speeds
Started to hear noise from passenger side front wheel at higher speeds and will disappear when turning wheel to right.
From what I have been reading this sounds like it the wheel bearing.
Is this a easy repair or is more work than it sounds.
Autozone shows wheel bearing and hub as separate pieces.
when removing the parts from the car do they come out as assembly or in parts
Toyota - Corolla :: Strange Noise Noticeable At Speeds Higher Than About 30 Mph
2004 Corolla, 100,000 miles. It makes a strange sound when moving. It's noticeable at speeds higher than about 30 mph. It changes with road speed, not engine speed. It's similar to a failing wheel bearing sound. I've stuck my head out the window on each side of the car and can't localize the noise. I checked for deflection in all four wheels, and they're all tight.My next thought was a transmission problem. I checked the fluid and found it to be at the proper level. I doubt if it's ever been changed. I drove the car and released the accelerator, and I put the transmission in neutral. The noise did not change. I'm not sure what that tells us, but it's another data point.
Currently I have the front wheels off the ground. If I run the drive system to 30 to 40 mph that way, the sound is not there. I don't know that both wheels are going the same speed, so I'm not sure it's an accurate test.I've checked wheel bearings before on my Cavalier and easily found the defective one. I could tell which one it was by hearing the noise while in the driver's seat, and the check verified that. I think I know how to find a bad wheel bearing, but maybe there's another test I don't know about. I'll search online.Maybe it's a noisy tire. I can't locate the source by ear, and that's something I'm usually good at. I wonder if the transmission or differential might be making the noise but only when it's under an actual load.
Prius (2004-09) :: Low Pitched Roar Or Whine Coming From The Front
About 3-4 months ago, I noticed a low-pitched "roar" or whine coming from the front of my 07, especially at 35mph and above. The pitch of the sound gets higher the faster I go, but its never a high-pitched squeal or anything, just a roaring whine that has gotten somewhat more noticeable as time has gone on. 184,500 miles on the car, Goodyear Assurance tires that will probably need to be replaced fairly soon but are certainly not bald, reasonable tread left. I bought the car with just under 160K, I've put about 25K miles on the tires, but don't know the car mileage when the tires were originally installed.
I had the tires rotated during an oil change about 6 weeks ago, which made little if any difference in the sound. I asked a mechanic I know (and trust) at the non-dealer where the oil change and tire rotation was done, he said to turn slightly left and right while driving to see if the pitch changes, which may indicate a front bearing problem. There was maybe a slight pitch change in the whine when I did that, if any. He said it might be the start of a bearing problem. I also don't notice any change in the pitch or unusual behavior when making turns.
So is this a tire problem or front/rear bearing issue? I'm going to take it to the mechanic for him to test drive, would I be better served going to a dealer? Given the car mileage, it could very well be a bearing problem, it would certainly be due.
Passat (B5) :: 1.8T Down Pipe Drone At Freeway Speeds Coming From Engine Compartment
I can hear a drone at freeway speeds coming from the engine compartment of my 99 Passat 1.8. I don't know whether this is normal, but it seems like the down pipe has a resonance/vibration. How to reduce this? Test pipe? Header wrap? Or is there something wrong that I have this buzzing?

2002 5.4L XLT. Just want to upgrade the exhaust on a budget to get better mpg. Pretty settled on a Flowmaster 40 swapped in, no fancy pipes or tips or anything. Just wanted to know how the interior drone was at highway speeds (75-80). I drive 15-20 min of highway to/from work give or take if I get off and take back roads home.
View 6 RepliesElantra MD (2010-15) :: Sunroof Making Noise At Higher Speeds When Opened
Today was the first day I drove my Elantra on the interstate with the sunroof open. When I was cruising at 65-70mph, I kept hearing a noise that I thought was coming from another car. It sort of sounded like a popping or thumping noise. After a few minutes, I reached my hand up and noticed the sound was coming from the metal bar that rises up a little at the front of the opening when the glass slides back. The wind was vibrating it and making it flap in the wind.
View 2 RepliesChevrolet - Blazer :: Noise Appears Around 30 Mph / Increased Slightly At Higher Speeds?
I "think" I may have a bad wheel bearing. Problem is, which one is it? The code reader I own does not read for ABS. The noise appears around 30 mph. It increased slightly, at higher speeds. I tried jacking each side of the truck up and checking for play and noise. There is no play. The only thing I can say is that the passenger side wheel seems heavy to spin. But spins.
The drivers side wheel spins slightly more free, but has a faint sound like the brake shoe is touching the rotor. I drove it and tried turning left and right. The noise does not seem to get worse or better when turning either direction. I called my local Auto Zone, and they only told me to do what I have already done. So I am at a loss. What else can I do? My Blazer is a 2000, 4X4, Automatic.
Passat (B7) :: Ticking Noise When Turning At Higher Speeds - ABS Or Traction Control?
I've been hearing a faint but rapid ticking noise when taking faster exit/clover-leaft style turns (usually ~40mph). I think it's the ABS or traction control on the verge of kicking in because if I push it a little harder I do get the flashing traction control light on the dash, but the ticking is happening before that light comes on.
I'll ask the dealer when I do the courtesy 30 day inspection... I'm at the end of the 2nd week of ownership with 200 miles right now, so I'm still getting used to the car. (2013 Passat TDI SEL). Loving the 40+ mpg on my rush hour commute!
I did a search and didn't find anything on the B7 forum that might explain this noise. I don't think it's a CV joint since the car is new, it happens when going around these style turns either way and only seems to happen at higher speeds. I suspect it's just that the traction control is sensitive (or maybe I haven't scrubbed the tires enough yet to get good contact).
Prius (2004-09) :: Battery Vent Making Noise When The Temps Are Higher
I own a 2005 Prius with about 145,000 miles on it. I love it. However, I've noticed that lately, the vent in the back by the window will come on and make a lot of noise. Some research has told me that this is the air vent for the battery that is in the back, and usually comes on when the temps are higher and the battery is starting to get a little overheated.
View 11 RepliesAccent MC (2006-11) :: Squealing Noise Coming From Engine / Car Shakes At Higher Speeds
So I just got a bunch of work done on my car: the timing belt, spark plugs, serpentine belt and water pump were just replaced. I had the oil changed, the fluids changed, new front tires, and an alignment all about a month ago, but now every time i turn my car on there is a squealing noise coming from my engine (i assume a belt). Then when i get to higher speeds the entire car shakes, but more so on the drivers side. I have also noticed my brakes just starting to squeal as well, but the shaking was occurring before that. What it might be?

Santa Fe (DM - 2013+) :: Excessive Road Noise Intruding Into Cabin Only At Higher Speeds
It's only at higher speeds ( read highway travel ) that I have an issue with the road noise intruding into the cabin....mostly emanating from the rear, as best I can tell. I can live with it but I prefer not to.
I took my car to a buddy who operates a shop dealing with high-end stereo conversions, etc. Surprisingly, he said he deals with these issues all the time....including vehicles in all price ranges. He uses a product that he claims to be very effective at deadening the transfer of road noises. I had him look over my SF and make recommendations.
The product comes in fairly large sheets that are easily trimmed to conform to the spaces being treated. These sheets appear to be some sort of rubber based material. The product is applied to the inner surfaces of the car's exterior metal. Once applied ( primarily a gluing-on process ) the stuff adheres there, according to him, " for life ".
For application, he has to remove all the interior plastic pieces so he can get to the exposed body metal behind them. In my case, he would also do the rear doors so the interior door panels on those doors will also come off. Once he has access to all the areas he wants to get at, he preps the metal and glues on the product. According to him, getting all the plastic parts and door panels off, and then back on, is a snap.
Corolla / Matrix 2009-13 :: Knocking Noise Turns Into A Rattle At Higher Speeds
I've owned this vehicle for the past year. This 2009 Corolla XRS manual has a very annoying steering rattle which took me the whole year to finally breakdown and diagnose. There are many forums stating this rattle is associated with the intermediate shaft assembly #2. I did end up replacing this part 45260-02110, hoping this would fix the rattling or knocking issue. It did not, but smoothness the steering has improved. I removed the upper portion of the intermediate shaft to pinpoint the sound. Originally I believed the noise may have been coming through the bulkhead from the intermediate shaft #1 or steering rack. I checked under the boot and everything was snug. Then I rattled the steering wheel around and this what I found.
It seems the noise is coming from the pinion where the power steering motor meets the steering column. You can hear the knocking noise with settle steering wheel movements. As I move faster, the knock turns into a rattle at higher speeds most likely vibration from the road. At this time, I do not want to disassemble the whole column just to see if I can adjust the motor height (if possible).

Prius (2010-12) :: Regen Braking Force Less At Higher Speeds At Over 45 MPH Or 70 KMPH
I have noticed recently that I seem to be getting less regen braking force than I used to. Particularly noticeable at higher speeds at over 45MPH or 70 KMPH. The regen seems to have very little effect now until I have slowed down. I seem to have to use much more brake than I remember recently. And by the way the battery in not nearly fully charged....Regen does come on but seems to have very little slowing power....
View 13 RepliesSonata NF (2006-10) :: Driver Seat Leather Cracking / Wind Noise At Higher Speeds
My 2009 SE V6, I have the grey cloth/leather combo and the drivers seat is pretty much cracking. I am not sure if it is cheap or the unusually cold winters we had here in MD. The car has 28,000. I am going to show to the dealer because in the cracks, the dye is coming off. I had a Trailblazer LTZ for 3 years and never seen that happen but it was tan leather.
Second, my car at higher speeds has a lot of wind noise, I think it is the mirrors. I am going back to the dealer for my 30k gouging soon and I will show them the seat again.
Lexus RX 2004-09 :: Static / Draft Heard At Higher Speeds From 2007 RX350
I'm new to the Lexus family. I recently bought a 2007 rx 350. It's in wonderful condition. I noticed that when I go above 60ish, I hear what sounds like a draft or a static-like sound. I've turned the radio off, air off, turned on re-circulated air, made sure all the windows are up, but no matter what I still hear it. I had a small Honda Civic before so I don't know if it's getting used to the aerodynamics of an suv? It almost sounds like there's a "crack" that's allowing air to come through the but there isn't. I don't notice it at all when I'm driving around town, only really on the interstate. It's most noticeable when in the drivers seat. I wasn't sure if it's just the nature of the ventilation system of this vehicle or should I have it checked? Am I just over analyzing?
View 6 RepliesCivic - Honda :: 2004 - Clicking / Grinding Sound At Higher Speeds When Let Off The Accelerator
As the title states, I've having a problem with my civic. It makes this clicking/grinding noise during 4 separate occasions:
1) turning to the right
2) going in reverse
3) applying the brakes <30 MPH
4) engine braking- I hear a grinding at higher speeds when I let off the accelerator.
2004 Honda Civic EX, 5 sp MT, 1.7 L, ~172k miles. I'm not a mechanic, but do almost all my maintenance at our hobby shop on base.
I first noticed this noise only when applying brakes approaching a stop sign. I checked my pads and rotors and they looked good. The noise is coming from the front drivers side of the car. Pulled the pads off and they appeared to be wearing differently (only slightly). Regardless, I replaced the pads and rotors. The problem persisted. I checked the wheels for play to see if it was a wheel bearing, but there is no play.
Then, I noticed the sound when going in reverse and turning to the right. All information I found pointed to a faulty CV axle. From the outside, the boots were normal. No tears, no grease. It didn't make any specific noise when turned, but oh well. I replaced both of them today. Replaced the transmission fluid with genuine Honda. Pulled out of the parking lot of the hobby shop and the noise persisted.
Ball joints appear to be fine, wheel bearings appear to be fine. The guys at the shop suggested maybe it was the caliper not engaging correctly; perhaps air in the lines. Tomorrow I'm going to bleed the brake lines and see if that works. Otherwise, when else would cause this noise? Video attached....
There are 3 parts to the video. 1 is the last few seconds of me slowing down from an on ramp. I click the turn signal apply the brakes and you hear the noise. The next section is again slowing down at a stop sign. The last section is backing up out of a parking spot.
