Toyota - Corolla :: 2002 - Engine Noise On Acceleration - A/C High Pitch Noise
Feb 22, 2016
I have a 2002 Corolla with about 180,000 miles that has been well maintained, but I know very little about cars.
Over the past months, I've noticed the engine noise on acceleration sounds a bit louder than I would expect it to, and it seems to be getting louder over time. It's slow changing, so I'm a little unsure. And occasionally I wonder if I don't hear a sound that shouldn't be there, though I couldn't describe it yet. Mechanic said the acceleration noise is normal at start-up for older cars until they get warm, but this happens even after I've been driving a while. Worth the $100 for an engine checkup?
Also, the A/C doesn't seem to be the strongest and has a high pitch noise when I run it. Normal?

I have a 2007 Prius 3 Touring Edition. I purchased it new in Dec. 2006. I have had NO issues with my favorite car of all time, and currently have 90,600 miles. I have noticed a high pitch for a long time coming from the transaxle during acceleration. The pitch is only present when MG1 or MG2 is engaged. The pitch stops in stealth mode. My finance also has a 2007 Prius, and her's does not make the noise or whine when I drive her vehicle.
I have changed the transaxle fluid at 65,000 miles, but I did not see the plug when it was changed so I don't know how much, if any, shavings were stuck to the magnetic bolt. If you are wondering, yes, the high pitched noise was present before the fluid change. Also, as I accelerate and increase speed, the noise pitch increases.
Is my transaxle displaying a tell-tale sign of imminent failure?

The car required a new water pump, the mechanic suggested to also replace the serpentine belt because of age - after a week the car made high pitch noise when started, the noise stopped after the initial start-at the shop it was explained that a new serpentine belt requires tightening after the car has been driven for a while - like a week- is this correct or was the belt not installed correctly....

My 2001 Corolla w/80k developing a considerably loud spark knock/engine pinging noise under acceleration. It throws no codes but pings like crazy and it never used to. It's happened gradual over a long period of time. I've cleaned the throttle body and have done all regular tune up items with no improvement. It doesn't ping at all on 93 octane, does some on 89 and terribly so on 87. Why is this? Does the 93 octane just act a a richer mixture of fuel to alleviate the ping? Should this sign point me in the direction that it's definately a lean issue causing the pinging?

I bought a 2002 accord with 105800 miles 3 weeks ago. I got the timing belt and water pump replaced within a week of that. I have noticed that the car makes a high pitch noise upon accelerating after replacing the belt. It does not happen always, but sometimes. I have noticed it on 3 days in last 2 weeks. A preliminary web search tells me that it could be a tight timing belt.

I have an 03 2.0 jetta manual shifter. Never had issues before this morning. Got in car and sounded like it wanted to turn but wouldnt turn over. After a few attempts the turning sound stopped and I heard an electric pop. Now engine won't even try turning when I turn key it just clicks and engine makes a high pitch noise. Took starter and battery out got both tested and they are fine...

I lost boost, went from being chipped at 16psi to 7-8 with a check engine code and a high pitch noise. Now is the secondary air pump connected to the turbo in any way. It just happened and I'm working on getting the code read. Just curious if my pump is just bad, what im figuring.

I have a 2007 Sonata, 2.4L 4cyl. and it is making some weird noise as of late. I have done some research and from what I have read it seems like it may be a bad engine mount. One thing to note is that the noise really only happens when the car is cold and hasn't warmed up yet or on a cold day.
Basically the best description is that the noise is a high-pitched rattle/vibration noise. The noise seems to match the vibrations of the engine but doesn't seem to get more intense if I rev the engine. The noise does get quieter if I put it in neutral but it is still there. The noise also happens even if the car is parked and off, and I do something like shut the door or trunk. I haven't gotten a chance to get in there and look under the hood myself to try...

I've noticed a noise coming from my car (2014 IS350 RWD) that sounds like a light, irregular rattle, when the engine is running in the 3500 - 4500 RPM range. I don't hear it necessarily under load, but if I am in manual mode in a lower gear, and let off the throttle, I can hear it.
The best way I can describe the noise is like a bowl of rice crispies (rapid and random), only slightly louder. You have to listen for it, the road/traffic should be quiet, and if you get back on the gas, the intake noise that's plumbed into the cabin pretty much covers it up. I can also hear it in Park or Neutral.... I've wondered if it's a loose heat shield, or an exhaust issue, but I can't hear it standing next to the car or with my head under the hood. I only hear it from the cabin. The rhythm of the noise is irregular.
I don't think it's ping/detonation, since that usually shows up under load, is much louder and has a decidedly metallic sound to it compared to what I'm hearing.

I replaced the timing belt an waterpump at 262,000 miles and ever since the engine makes a loud low pitch noise that varies in pitch depending on the engine speed. I replaced the alternator and it didn't work. I don't know if the power steering pump, a/c compressor or something else is making this awful sound.

I had the front right wheel bearing replaced on my Toyota Corolla (60,000 miles) replaced a couple days ago. One day after the repair, I heard a high pitched clicking noise which was noticeable around 20-30 mph. Yesterday, I still noticed the high-pitched sound but also a grinding/popping sound in front left side when coming to a stop upon every rotation of the tire. Took the car back to the shop to let them listen to the noise, but really weren't very compliant since it doesn't sound like a wheel bearing problem.

It was a very nice week and rolled my windows down at Disney resorts. I noticed a very high pitch noise that the brakes did not seem to impact.

My friend and I both have the MK4 R32. He had a bunch of stuff replaced in the engine. (a bunch of plastic parts that are super expense, the timing chain, something related to the guide, basically the plastics that holds the engine cushion/absorb) Anyways, his engine sounds great and quiet at the same time with a little high pitch noise when the RPM is hanging in between 1K and 2K.
Our cars were in the garage and I did the same thing and it sounded NOT quiet, a lot more noise than his. There was an obvious difference in noise coming from the engine with the hood open. I do have cams and a light weight pulley. Can that have an affect on the engine noise? If I am not making sense, then i should probably video record the sound or take it to the dealership for a check up. Also, I am at 93K.

We have an '02 Toyota Camry with about 92,000 miles on it that is making a weird intermittent "Whooping" noise. The sound starts low and then goes high. It seems to come from the dashboard or the steering column I think.
A guy at the parts store said he thought it might be radiator core going bad, but admitted it's hard to know without him hearing it.
I've tried to record the "Whooping" sound but obviously the car never makes it when I'm trying to do this or can be easily heard on a recording. Additionally we took it to a mechanic and they didn't hear anything!

I have a 2009 Gen. II with 48000 miles on it and it started having a high pitch noise when driving. Thought it was wind noise at first but does it at low speeds also. When you roll the right passenger side window down you can hear it much louder sounds like it is coming from the right front.
