Prius (Gen 3) :: 2011 Versus 2014 - Increasing Engine Noise / Vibration And Drone At Higher RPM
Jan 11, 2015
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.

I have a 2007 Prius (now has 220K + miles) I bought used about 2 years ago with 150K miles. I finally got used to the car sounds so this is something new, or rather it's becoming louder and enough for me to question it. The car is still quiet at low speeds but this sounds like something related to how fast the car is rolling, not the engine acceleration. It doesn't sound like it's coming from the wheels. It's a low roar like sound, not high pitched and it sounds like it's coming from under the middle to front of the car as if related to perhaps the drive train. If I am up to 40-50 mph and just rolling (foot off the gas) down a long hill, the sound is there. It gets louder the faster I go. Could it be a transmission sound? I've always had manuals so this is my first automatic transmission car.

When I press slightly on the accelerator just to get the truck moving and than let off the engine stays at the higher RPM typically just over a 1000. This only happens in drive not reverse and everytime I just slightly step on the accelerator. The truck only has 1K miles on it.

2012 Camry SE 4 cyl, 56K miles ... Happens in all gears, in normal and sport mode “under light acceleration” at 1600-2000 rpm.
Sitting in driver’s seat I hear a drone which sounds similar to the engine lugging we hear briefly at around 1000 RPM. In the 1600-2000 RPM range it is very annoying because this is the cruising range on highways. Sometime when going up a slight incline it can be felt through the accelerator.
When seating in back seat on passenger’s side, it sounds similar to a bad muffler/resonator and is very audible. Spring loaded exhaust couplings in front of muffler and between front pipe and converter are not seized. All rubber hangers are there. Installed “B-quiet” sound absorber in trunk going from spare tire well over top of muffler and up rear quarter panel which did not work. Nothing is touching the exhaust under the car.
When idling the exhaust produces a noticeable putt-putt sound. Toyota rep (not dealer) went for a ride with me and feels it is typical of a car “for this mileage” (same as dealer told me). I stated it did not do it before and was told cars wear in and after a while characteristics change.

In February I purchased a 2011 Subaru Impreza, 4 door sport with 26k miles, for 16,999.
Now 3 months later I have pilled on over 10k miles due to work, and constantly feel cramped with no space because I load so much into my car for my job (promotions and sales).
Recently, I have come across a 2014 Jeep Patriot sport with 15k miles for 19,600. The car seems to be in good condition inside and out.
Now I know nothing about Jeeps or cars as a whole really. But I do know that aside from size I love my Subaru.
Looking for opinions about switching from the 2011 Subaru Impreza to a 2014 Jeep Patriot?
Key features:
-I drive a ton
-Car is always loaded with stuff
-Fuel economy isn't a huge concern
-Subaru has over 36k miles
-Jeep has 15k miles
-In three months I have put over 10k on due to work
Stay with the Subaru or move to the jeep?

I have a 1999 Forrester "S", automatic with ~100k miles. This started intermittently but now is consistent. At about 45 mph or higher the rear of the car will shake with increasing intensity. It feels similar to a bad strut that allows the axle to hop. I have checked the balance on all the wheels, bearings feel free, nothing seems to be loose in the suspension, have placed the car on jack stands and run at 60+ with no vibration. My best guess is the carrier bearing or rubber suspension on the drive shaft. It is hard to evaluate in the car.

I kept a record of every drop of fuel used in my 2008 Gen II Prius. It was easy with only two simple screens: Energy and Consumption. After writing down the numbers I reset the Consumption screen at every fill up. I entered these into a spreadsheet that did a bunch of calculations telling me all kinds of interesting things.
Now to my new 2014 Prius v Two. I'm confused regarding all the new information available. (A good thing) Which screen and number am I looking for that is equivalent to the Miles and cumulative MPG on the old Gen II?
Would like to sort this out before my first fill on the new car.

I am a proud and recent owner of a 2015 Sonata Sport 2.0T!
Car looks amazing and am very happy with it.
But lately I have been noticing lots of drone noise coming from the engine, and a really loud cold start as well. The "cold start loudness" goes away after a little bit of driving.
Was wondering if this is just the way the 2.0T sounds, or should i get it checked?

I have what seems to be flat spots on both my rear tires. I've been getting a drone sound and vibration from the rear end and thought it was bad wheel bearings, but when I had it up on the lift the tech said my rear shocks are bad and caused this tire wear. The shocks aren't leaking and the handling seems fine...I don't get it.

My car definitely has a driveline vibration, but the steering wheel also vibrates. All vibrations are, however, intermittent as to when they come and go, and the intensity - on both the chassis and the steering wheel - can also vary.
Tires and wheels have been ruled out with 99.9% confidence at this point... What puzzles me is how a driveline issue in a rear-wheel-drive vehicle can affect the steering wheel (even though it can certainly explain the shaking of the whole car). In the end, it's all connected to the same body, but still... I am even wondering if my car has this driveline vibration PLUS something else (e.g., control arms in the front suspension appear to be a popular replacement part in these cars according to other threads).
Here is a link to the TSIB that I borrowed from another thread: [URL] ....

Purchased 2011 Prius 2 with 108500 miles on 4/29/2015. Didn't fully check all climate control settings and fan speeds. Two days later, car had vibration and rumbling sound which was increasingly severe on three highest climate control fan speeds in all modes (e.g. AC, heat, auto, manual, etc.). Sounded like a quiet lawnmower on highest fan speed. Was quiet on three lowest fan speeds. Glove box and passenger side dash vibrated in sync with noise.
Cabin air filter had been replaced by a large Toyota Dealer as part of pre-sale prep. I suspected filter was not installed properly. Removed glove box and filter, which had been properly installed. Vibration/noise were same when fan was operated without filter or glove box installed.
Felt around inside of fan housing. There was debris, including seven pieces of acorn shell (see image below). The concave sections of the shells were firmly wedged in the fins of the squirrel cage (no pun intended!) impeller. Cleaned out all nuts and debris, reassembled, fan operated quietly without vibration at all fan speeds.
The shells essentially unbalanced the impeller and induced vibration at high fan speeds, just like an unbalanced wheel would induce shimmy or vibration at freeway speeds. What is baffling is how the debris and acorn shells this large got past the filter. Filter fit on the right side is pretty good since a plastic flange goes between the pleats. The left side appears to have a looser fit with some gaps.

I have a 2014 Passat TDI with a 6 speed manual. When the clutch pedal is depressed between upshifts, there is an audible groaning sound and a vibration in the clutch pedal. The dealer replaced the throwout bearing but the problem persisted. They then replaced the entire transmission and the noise/vibration is still there. The noise follows engine RPM. Is this normal for the TDI powertrain? The dealer had never encountered the noise but they did find another car on the lot with the same noise.

So my car (2001 Civic) was having some issues that I needed to get worked out, so I was driving my mother's car for a few days. Within the first few minutes I knew there was something wrong, but I had so much going on that I haven't had a chance to get back to it for a while.
So she has a 2003 Toyota Camry with just 39k miles. Her work is about 2 miles away from home, so it basically gets driven there and to get groceries, and local clothes shopping. The car basically never sees the highway.
Hard to describe the sound, but it's like a loud rattling/vibration with every revolution of the front wheels. It sounds like it's coming from the front passenger side. Either the tire or the engine area. Here's a video of it on youtube. You can hear it pretty clearly under the road noise. It sounds kinda of like going over train tracks or something, and I'm only going about 45mph in the video. [URL] ....
So I don't know much about the car, but I am very familiar with my civic, so I checked out a few things. The tires appear to be in pretty good shape. About half the tread left with no unusual wear. I doubt it's the tires, cuz it really doesn't sound like tire noise. I checked the engine mounts and they appear to be in good order without cracks. Wouldn't expect an engine mount to go at 39k miles either, regardless of age. The car is garage kept.
Neither wheel has any side to side or up and down play like a bad ball joint, tie rod end, or wheel bearing would have. The steering wheel doesn't vibrate or anything. The sway bar endlinks appeared to be in good shape. I just changed the brake pads and rotors because of an unrelated issue. It didn't fix the problem.
A couple of things I will note: The belts are kind of dirty. It was really weird because half the belt is brown, the other half is black. It's basically split down the middle of one side. It's just dirt though, as I was able to rub some of it off with my fingers. The car was in a minor accident a couple of years back. It required me to replace the bumper and the passenger side headlight.

I have a 2014 Sonota GLS purchased in February of this year. Kept all service dates and oil changes. Have a problem with engine noise? Not like low oil knocking or anything, just cheap engine loud?

Had a long trip with the X this week and noticed a weird vibration up at speed. Anything before 65 mph and the truck was smooth, higher than that a medium vibration developed. Its frequency increased with speed. Never got the truck over 70, but the vibration was there enough to rattle change in the cup holder and the rear view mirror. What it might be? I was thinking a hub bearing... 2000 Limited 4x4 PSD ....

I have two simultaneous problems with my 2005 Elantra (automatic transmission). I don't know if the problems are related or not, or if they are alarming or not.
Background on the car: timing belt and water pump replaced in 2010; four tires new in 2010; oil changes every 5000 km.
The first is that my engine is making this 'whirring' sound when I approach 80km/hr. It's not high-pitched, but more of a droning noise. Having read around the forums, I see that Elantras commonly make funny engine noise, but this is fairly new to my car (145,000 kms) and definitely not there at all when idling or at low, city-street speeds.
Additionally, I have a weird vibrating noise coming from the front left of the car only when I am dead stopped and the brakes are fully depressed. It doesn't make this sound in park, and I don't hear it until the car has come to a complete stop; there is no odd noise while slowing down.

So I changed my oil today and added about 9.8 - 9.9 quarts. There was just a little left in the second 5 quart jug. I carefully added some oil while checking the dip stick frequently. I made sure the level was just at (maybe a hair above) the top dot on the dip stick. After that, I went out for a spirited drive.
Now 4 hours later, when the car is relatively cool, I checked the level again. However, the level is now significantly higher than before. It's definitely past the top dot, not by a lot, but definitely more than before.

I have been driving my 2014 Sonata GLS in Sport mode with no problem. However, two days ago the engine got extremely noisy. I checked the Comfort and Normal modes - definitely no scary noise. Is this common?

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.

When I use my automatic transmission to slow my vehicle on steep downhills, the RPMs are much higher than when the engine idles because I use my brakes. The pistons are firing many more times per minute - so am i using more gas? Is the answer different for a standard transmission?
My "mystery vehicle" is a 2011..... outback...

I just left to get gas. When I left my house, I had 64 miles til empty. The gas station is about 4 miles away. I put $5 in and when I got back in my car it was reading 59 miles til e. so I drove to another gas station and put another $5 in. This time, it showed 56 miles til e which is where I was before I got gas the second time. I have tried to reset it but can't figure out how to... I've got 90 miles until my warranty expires... Any easy fix? Or do I need to bring it in?
