Prius (Gen 3) :: Loud Electrical Noise From AC Compressor When Warming Up Outside

Just got a new 2010 Prius III with 78,000 miles. I recently have had the car out when its been warming up outside and I noticed that when the AC is on every now and then it will make (in my opinion) a very loud electrical noise. I took it to the Toyota dealership and they said that the noise is normal (I even showed the person that checked my car in this exact video) however I question if they really heard the noise I was complaining about because it doesn't always do it (which is another reason I wonder if it isn't normal). Keep in mind my phone is close to the source of the noise so with the hood closed its not as loud but its still VERY noticeable.

Ford 6.0L Power Stroke Diesel :: AC Compressor Making A Loud Growling Noise

AC compressor makes a loud growling noise and lugs the engine briefly when engaged at idle and the truck has been sitting for weeks. After that initial grind, it works perfectly and makes no harsh noises. Can I replace the compressor bearing or should I swap out the entire compressor?

Santa Fe (DM - 2013+) :: Loud Wind Noise Between 60 - 80 Mph

Purchased a new 2.0T Santa Fe this weekend. While driving it home from the dealership noticed a loud wind noise between 60-80mph. We took it back to the dealership within 30 minutes and talked to the service manager. They put us in a loaner Genisis and said they would take the front end apart and see where the noise was coming from. The dealership called back this morning and said they can't figuer out what/where the noise is coming from but they do agree it is a wind noise.. They are offering to swap the vehicle out with another one next week when it is delivered. High pitched noise while driving on the freeway?

Prius (2004-09) :: 2006 Engine Noise - Loud Fan Like Buzzing / Especially Loud On Highway

For the past few months I've been hearing a loud fan-like buzzing noise coming from the passenger side of the front of the car. I don't know that much about cars, but it almost sounds like the engine is racing or something is spinning too fast. It has gotten increasingly worse, and seems especially loud at high speeds on the highway.

It is not the heating/cooling fan - the noise is present when the heating/cooling system is turned off.

Lexus GS 2013+ :: Loud Whine Noise When Rev The Engine

Ok so a few days ago when I was at an ATM i stopped and revved my engine, i could hear a whining sound like bee/supercharger type. It gets pretty loud when i rev the engine and you could hear it whine down as the rpm drops. Now I put it in Sport mode and on drive and when I hit the gas I could clearly hear the whining noise even in the cabin, specially when I let off the gas and let the Sport mode keep the revs up high.

Pretty sure it has done this since I bought it, but I always have music on so maybe that's why I didn't hear it til now.

Elantra MD (2010-15) :: 2013 GL Loud Noise Over Bumps

Picked up my brand new 2013 Elantra 2 nights ago. 51 Km's on it when I drove it off the lot. Immediately noticed it was making a very loud noise whenever I hit any road bumps, potholes, sewers, train tracks, etc.

I can't tell if it is coming from the front, or back of the car. Many of the threads on here seem to be talking about a common rear shocks issue? Also read a lot about faulty struts? Swaybar?

Accent RB (2012+) :: 2013 - Transmission Noise / Loud Bang

Ive got a 2013 Accent with 16,000km on it. It has an automatic transmission. The noise is when i pass from R to D, or P to D. It is an intermittent noise, so it does not do it all the time. But when it does, it makes a loud "bang" that can be easily heard and felt in the floor. Ive had it checked by the dealer, but it never does it when its in the shop.

I always let the idle go down before shifting into gear and even if i hold the brake hard to change gears it does it anyway. It doesnt matter if the trans is cold or hot. And no, i never change gears when the car is still rolling, always when i have stopped completely.

Elantra GD (2013+) :: Loud Click Or Snap Noise While Turning

Finally took the car ('13 GT) back to the dealer to have them deal with this noise. Every time I turn the car left or right, I get a loud click or snap noise from the right front. My first thought was it was something in the suspension loading and unloading as the weight shifts from left to right. So, brought it in at the 59,000km mark, the looked at it, drove it around and finally said they re-torqued both axle nuts as they were loose (didn't even get into THAT one)

Soon as I drove it away, it was still doing it. I lived with it for the last 6,000km and finally got sick and tired of it so I took it back. Same deal, but this time they say the right axle shaft is shot.

Lexus GS 2013+ :: Loud Engine / Vibrating Noise While In Idle?

I upgraded from a 2009 ES 350 to my 2013 GS 350 recently. One huge difference I noticed is the sound of the car while in idle. My ES was so quiet that sometimes it was hard to tell if it was on or off when parked. My GS has an irritating vibration noise from the outside that is very noticeable when I'm parked. I can hear it when my windows are down and I'm sitting in the driver's seat. It's not loud, so to speak, just incredibly irritating to the point where the vibration hurts your ears. When I'm in my garage and the sound is a bit more isolated, it sounds the loudest from the driver-side mid-to-back section of the car. However, the car itself doesn't feel like it's vibrating.

I also noticed at times when I start my car, my engine gets loud and the RPM shoots up to a bit past 2 (while still idle), then quiets down and evens out. Is this normal for this gen GS? The only reason I ask is because neither of things happened on my ES, so either I'm not used to it, or something is wrong. Driving/ performance seems normal. I do understand this engine should be a bit noisier than my ES and I am enjoying the extra HP and AWD ... I have a full, unlimited mileage warranty so getting anything fixed won't be an issue. My main concern is wasting my time going all the way to the dealership and embarrassing myself if it's completely normal.

Santa Fe (DM - 2013+) :: Loud Clicking Noise Inside Steering Wheel

On a recent trip to the service dept, I mentioned that the steering wheel makes a loud clicking noise anytime it's turned, the service guy said "it's normal and supposed to do that it's a spring"... Really? I find it hard to believe that Hyundai would make us listen to this annoying sound all the time.

Lexus RX 2010-15 :: 2013 - Loud Noise While Shifting From Reverse To Drive

I recently leased a 2013 RX 350 and started hearing a weird loud noise almost in the first week itself. It seems to happen whenever I shift the gears from Reverse to Drive. The loud noise comes from the back of the car and anyone sitting in the car (speakers turned off) can hear/feel it. It seems to be worse in the morning (or when the engine is cold).

I took it to the lexus service center and the person told me something about differential pressure, which I really didn't understand:-). However, he said nothing can be done and its not a safety issue and sent me back home without any fix. I have driven many cars in my life so far and never ever came across something like this. Is it something normal at all?

Prius C :: Noise From Air Conditioner Compressor

Just put my car in for it's first year's service(20,000 km). I made an observation to the service tech that during warm weather, there is a noticeable rattling whirring sound.

During testing, they were able to compare my car with another and confirmed the noise to be from the air-con compressor.

Prius (2004-09) :: AC Compressor Noise When Braking

Quick back story, bought the car a year ago, seller told me it was in an accident and the radiator was replaced. He let me know that the discharge AC hose was missing and that the other hose was disconnected. I also noticed that the low pressure cap is missing. I recently ordered and installed the discharge hose with the intention of filling the system later.

I have always noticed a noise/vibration coming from the passenger side when braking at low speeds. I havent noticed at higher speeds but maybe there is more road noise. The best I can describe the noise is that is sounds like a compressor running. I have a hunch it's the AC compressor and might be related to the regenerative braking, but I am no expert.

Prius (2010-12) :: Air Conditioner Compressor Noise

I have a 2013 Prius with few miles. It seems like the air conditioner compressor makes a very loud humming noise. It's a little annoying inside, but outside it is really loud. I know it is running off an electric motor and I expect that to make some noise, but this seems excessive. Is this normal? Also, the compressor keeps running all the time. I thought they were supposed to cycle on and off. It seems like all air conditioning compressors do this to conserve energy, even a house air conditioning unit.

Lexus GS 2013+ :: Loud Whistling / Squeaking Noise From Driver Side Mirror - GS350

I recently upgraded from my '14 IS 250 to a '15 GS 350. So far I am loving the car except for one thing. When driving above 50mph, there is a very loud whistling/squeaking noise coming from the driver side mirror area that is driving me crazy when the window is open. If i close the mirrors, it goes away.

I plan to have the dealer look when i go for the 5k service.
