About a month ago, I purchased my 2013 Prius Four. I've put on about 2,500 miles so far and recently started noticing when I start the car up, it is giving off a high pitched squeaking noise. This happens both when the car is using the electric battery and when I can feel the gas engine kick in. After about a minute or two, the noise goes away and doesn't come back.
View 5 RepliesI have a 2001 Toyota 4Runner SR5 with AT and V6 with 70k miles on it with pretty much everything loaded. The car has been trouble free since I got it 3 months ago. However,the past month, the engine has been making a high pitched "squeaking" noise whenever im at a constant speed. If I accelerate or brake, the noise goes away.
I also noticed today that it stays constant no matter what when I am in 4WD mode, but when I am in 2WD it behaviors like I describe earlier. I had the Toyota dealership do a complete lube service and they found two of the belts were "dry" and re-lubricated them however the problem persisted. The noise doesn't happen when im in idle or at a stop either. The noise seems to emanate from the right side of the engine.
Also, do 4Runners have a noisy brake cylinder system? Almost every time I brake I hear this slight "Pssssssssssssssssssss Tick!" sound from the engine. The car brakes just fine and the Toyota dealership found nothing out of the ordinary but i've never heard a car break that noisey before. This a 4Runner trait? What could be causing these two noises, especially the gawd awful squeaking noise from the engine. It never made that noise until just one day..
I have had my certified 2010 Prius II, not two because it is a 2010 and 2010 used uppercase roman numerals for model designation, with 82000 miles about 3 months and sometimes when I apply the brakes I hear a high pitched whirring noise. I think the closest thing to compare it to would be a skill saw but not that loud.
View 2 RepliesWhat is causing this strange noise. I have an old 1998 Subaru Impreza that runs well but has this mystery squeaking noise coming from the area near the front left of the car. It seems to happen most on cold, dry days, and I can hear it when the car shakes, but only when it is driving, never at rest. I can usually make the noise if I let up on the gas while still in gear, and it happens sometimes while going over bumps, but typically only if the bump only affects one side of the car. If I am accelerating quickly or braking, the noise usually doesn't happen. It also usually only happens when I am in gear and have the gas pedal pressed, but it can still happens on bumps even if the car is in neutral, the noise is usually much quieter if the car isn't in gear.
I can't tell if the noise is coming from inside or outside of the car, but it seems to be louder inside and I can't hear anything from outside when driving through a parking garage with my windows down.Now this noise first appeared a few days after I got my clutch plate, fly wheel and axles replaced several months ago but I haven't been able to find anything on my own and the shop said they didn't see anything that could be causing it.I have included a recording I took while driving, if you listen its the high pitched squeaking. So far the only thing I have done is checked the sway bar and bushings and those are all in good condition and covered in lube.
When starting in morning (even if weather is warm) or after car has sat for several hours, my 1999 Taurus makes a high-pitched whirring noise. Thought it was a loose fan belt, but mechanic said that was wrong. Have taken it to several mechanics and, of course, it doesn't make the noise after I've driven it there. Have to leave it overnight, which is HUGE problem as I don't live near public transportation. Noise occurs several times as I shift into DRIVE and then accelerate. After that, it disappears, then comes back again, if I leave it sit for several hours. One mechanical friend checked the tranny fluid and said it's fine. Also said it is probably not the tranny but didn't know what it could be. I took it to one of your recommended mechanics, but they couldn't find anything and said they didn't even hear the noise, although I did leave it overnight at their garage. (Won't go back there again.)
View 5 RepliesYesterday I noticed that there was a high pitched squeaking noise coming from the front of the car as I was driving. It was loud enough to hear over the radio, which I muted to confirm where it was coming from. It sounded as if it whatever was making it was rotating, if that makes sense. It was the most noticeable from speeds 5 mph to 30 mph, but I couldn't tell if it was the wheels or engine compartment. I have 4300 miles on it.
View 6 RepliesNoticed the barely audible (with good ears) high-pitched sound that emanates from the car when you let off the throttle enough to prevent any charge or discharge bar from showing? It goes away if you completely release the throttle or if you press the throttle a tad bit more.
View 19 RepliesI drive a 2002 4-dr 1.6 L Accent and there is a strange, high-pitched squeaking that comes about from somewhere under the car at very slow speeds (30 mph or below). If I hit the brakes, the noise continues sometimes as the car slows. (The noise isn't the brakes, though, I know that), but if I hit the gas pedal slowly, the noise stops. Whatever is vibrating underneath doesn't seem to be causing a problem at high speeds. Or I just can't hear it.
Secondly, I am going to try to do some tune-ups for the summer for lack of better things to do, mostly, I can pretty much do anything (intake/exhaust, engine, electrical) as long as I can find detailed instructions.
I drive a 2010 Golf Wagon/JSW, and when I'm going at speeds around +60 mph/90 kmph and lift off the accelerator a faint high pitched whirling noise comes on. As soon as I tap the gas pedal it goes away. What this could be?
It's been a week now since I've noticed this, I guess I've never noticed it before or it's getting louder..i don't know?
i proudly own a 1986 4runner and i loved it ever since i got it. but i noticed on the way to a buddies house, a really high pitched squeaking noise...almost like a mouse. I just set it aside and turned up the radio. well this morning it was really getting worse. it was more audible and I am sure others can hear it in the parking lot of my school.
Also, I have another problem (trying to kill two birds with one stone here) i went to start the truck the other morning and its getting really really cold, about freezing point and when i started it up, the engine was idling at about 500rpm and there was a really loud noise under the hood, it sounded exactly like a vacuum cleaner. I quickly turned it off, hoping the started didn't stick or something, but the engine stopped and the vacuum cleaner noise stayed for about 4 or 5 seconds. I waited a few minutes and tried again and started right up and idled correctly. got to school, turned it off and started it back up and started correctly. went out there in the afternoon and it did it very shortly and just idled right. it still does it just barely every morning I start it.
I bought a CPO 2010 Camry LE (2.5 4 cyl, 6 sp auto) a few months ago. The car had around 34K miles when I got it, and ever since then, it has had a high pitched whining noise when accelerating or revving the engine in park. It is noticeable from around 2500RPM up, and seems to be a little louder when the engine is cold.
I have left it at the dealer twice, and both times they have come back and said it is normal. I can't believe this, because I have owned many cars over the years, most of them being fairly dilapidated, yet most of them haven't had a noise like this. I think I have read a comment online somewhere that an issue like this was found due to a bad power steering pump .
I was driving today and had just gotten off the highway. I was going at no more than 10MPH when I heard some high pitched sound. At first I couldn't figure out what it was and thought maybe it was some outside noise. It quickly got louder over the span of the next few seconds and then I realized it was the engine. I had the pedal barely down so was definitely in electric mode.
I quickly glanced at my Scan Gauge and actually saw the RPMs go from 1200's up to 3400 in no more than 10 seconds. I have never had the car rev this high, probably just 2400s when I'm on the highway going 70's. By this time I was getting very perplexed and worried, and had my foot completely off the gas pedal. I immediately pulled to the side of the road and parked (hit the P button). The car seemed to go into park mode fine and then over the next few seconds the RPMs went back down to 992, and I made it back to the house no problem.
This is kind of an odd ball problem since I have not encountered this before, but every time I turn my wheels full left or full right and start moving a really high pitched squeaking sound comes from the front of the car. Is it bad alignment or wear sensors on the brake pads rubbing? the brakes have a lot of pad left so i find that hard to believe.
View 5 RepliesI've noticed more and more that when I am braking that I heard a high pitched whining noise. Sort of this ultrasonic type sound. It will only go away if I depress the brake pedal very firmly after being completely stopped. However every so often the firm press will not stop the noise. I hear it more in the evening on the way home than in the morning to work, though I may not be paying attention as much in the A.M. due to morning brain fog.
I don't hear it any other time. I'm worried something is wrong with my inverter.
I have a 2010 Corolla S Got it brand new in november of 2009. Its been 5 years since I had it and never had this problem.
So this has been happening for a month now, and I can't figure out what it is? It only sounds at first startup of the day when the engine is cold and only sounds off for 1 second right when you start the car.
My Prius IV with about 10K miles started to emit a high-pitched electrical humming sound under the hood when it was in Ready mode. It did not have this sound before. I opened the hood and found the sound was coming from somewhere around/under the engine area. I want to know if this is normal on Gen 3 Prius? I have seen post on the same noise in Gen 2 Prius but the posts (thread) stopped without a resolution.
View 19 RepliesI have had my gen3 Prius for two and a half years and have covered 65,000 miles.
View 11 RepliesCar suddenly started a high pitched whistling noise/metal on metal sound at highway speeds. It is intermittent, no noticeable pattern w/acceleration or braking. Similar sound at lower volume when the shock/spring is depressed (pushing down on that corner of the car). Louder at low speeds.
View 6 RepliesI took my 2008, 56k in for a new battery after my car sat outside in negative degree temps for a few days. After doing that repair, the dealer recommended a new serpentine belt. Ever since that service appointment, the car is making a high-pitched "woo-wooo" noise during acceleration. It's definitely a noise I've never heard before. I took it back to the dealer two days later; he had the service guy drive it and they both claim the noise is normal and just due to the cold. Is it the belt? Is it the cold? Am I losing my mind?
View 3 RepliesI'm completely new to hybrids. I have a 2001 Toyota Prius with 146k miles and its been running very good until some weird things started happening during the past couple of months. When I start it up, the brake light and abs light come on along with a steady high-pitched noise and grinding noise (sounds like ice being scraped). While the lights are on and the sounds are being made, the brake becomes very soft/"spongy" and goes down to the ground without much force at all (It usually always does this when I start it up and sometimes - but not very often - when I'm driving). Sometimes it all goes off and everything is normal again after about 10 mins, sometimes all day, and sometimes only after a minute or two (It usually does it on a cold start, but sometimes even if the engine is heated up, it does it).
View 8 RepliesI know this noise is the Thermos Pump and it operates when I turn the car on and off. Question - is it failing - also a really annoying noise, but I'll put up with it as long as nothing's breaking.
