Prius (2004-09) :: 2006 - Screechy Noise Especially While Accelerating?
Jun 6, 2016
I recently bought a 2006 prius used with 100,000 miles and have been hearing a very disconcerning sound coming from underneath the car. It is a screechy noise that is always there, but especially when i accelerate or break going up a hill. I have had it checked out by both a dealership and an independent mechanic neither party has info what it could be, even after hours of troubleshooting, as well as showing then a video in which you can hear this awful sound.

B2200 mazda: I've recently got a screechy noise only when in gear but gas pedal NOT depressed. Could this be an indication of a bad U joint noise? Or? The noise seems to be coming from the rear chassis of car. Noise seems worse if going in reverse. Possibly coincidentally I started noticing the noise after a shock absorber worked its way loose, causing lots of racket. (The mechanic who'd installed it has since tightened it.) Would all that rumbling from the loose shock have caused something to break or work loose? Or is it just age of vehicle (22 yrs) By the way, the noise is very similar to a wire scratching metal. I also have had the classic thunk noise of a u joint, for a longer period of time-- never looked into though.

My 2006 is having acceleration/power issues. It won't go above 35mph while being very slow accelerating. Toyota diagnosed it as needing a new battery so a new $2K battery (not rebuilt one) was installed. It still has the same problem. It seems like a problem between the electric/gas power transfer.

I just bought a truck, it has a whining noise while accelerating, stops while letting on the gas, does not do it in neutral even if i rev up the engine. Only whines while there is some force on it, ie.. accelerating, or going up a hill at any angle, and does it from about 10-15mph- atleast 60mph.

So after doing some troubleshooting and researching in trying to find out on my 87K 2008 Prius Std "Noise in the engine while accelerating", "Approximately 10% reduction in fuel efficiency, due to lack of power from engine" & "Glide seems to be degrading over time", here is what I have observed.
1) When I push the gas when the car is parked the engine does not seem to rev in a stream, it goes up for about 3 seconds then goes down for 1 second, then again goes up and then down and this keeps happening until the gas pedal is kept press. In conventional cars the rev should be streaming continuously and proportionately to the pressure applied on gas pedal. This almost seems like a misfire, but from the drivers seat I do not hear any blasts, I have never tried this before so I don't know if Prius's are suppose to be like this. Also no Alarms on the MFD.
2) After using the 5.25 oz fuel injector cleaner in back to back half tanks I saw the engine regaining power and hence bettering the fuel efficiency. Does that mean I should get a Fuel Injector cleaning done by Toyota?

I recently changed my oil, transmission fluid, and both coolant systems. I have a 2008 Prius, and I can hear this noise coming from the engine when I accelerate between 50-70 MPH or have the cruise control on.
I had low coolant in the ICE system earlier (didn't know there were two separate systems) and I had the red triangle light up for a moment and "Problem" appear on the LCD screen followed by an orange thermometer. I pulled over and let it cool down, and babied it home and added coolant.

Started up my rig yesterday and heard a very strange screechy sound that got louder when I rev'ed the engine. After a minute or two it went away. Same sound this morning and whenever the truck sits for more than an hour. Sounds like a turbo problem and is coming from that area under the hood..?

Over the last couple of days, my 2009 Sonata V6 has developed what I best can describe as a rattling noise near the engine when I am accelerating the vehicle (noise changes based on throttle input). I only hear the noise with the car in drive, if I shift into Neutral or when I am in Park I don't hear the noise when I rev the engine.

Today I noticed a pinging noise on the highway when accelerating around 60 mph. It certainly doesn't sound like its coming from the lower end and it happened with the engine fully warmed up. I've always changed the oil on time, never has it overheated and it performs very well otherwise, no power losses.
No check engine light is on. In fact, I have heard this same noise on older cars I have owned (Cutlass Ciera) around the same mileage 105000. I am thinking of adding an oil additive, and I have heard that 1 Qt of ATF fluid followed by a drain and refill works well.
I might also do a fuel system purge, BG's has a good machine for that Could this be an EGR issue? Replacing EGR valve? If so was it easy and where is it located. I am hoping I didn't break a valve spring....

I just installed a k&n CAI on my 3gs and i noticed a whistling noise when you accelerate from a stop and when you blip the throttle. If this is normal with a CAI or if something is wrong. I've checked for air leaks and made sure everything was installed correctly.

Tonight while driving and accelerating fairly hard we began to hear a noise. The car sat parked for roughly 5 hours and then we began to drive it home (apx. 12-15 miles). About halfway through the drive the power steering went out and the battery light came on. The battery light would turn off and the drivers seatbelt light would come on even while it was buckled. These two lights alternated being on and off 2 times each. We heard something that sounded like a rock got kicked up into a wheel well. After getting the car home with no power steering we noticed the car had begun to run very hot. almost all the way up the gauge.

I have a 2006 Chevy Trailblazer and the past few months, there is a whistling noise when I accelerate but only when the air conditioner is on. Now I have noticed that the air is not that cold. Would you know what the problem is?

I have an 06 Prius that I have had for about a year or more now. When I bought it, it needed a transaxle. I replaced that and have been driving it since. I have this problem that seems to be getting worse. When I push the brakes the car will make a popping noise, and it seems to be getting more frequent. I do not get any noticeable noises when turning or just driving normally.
The noise is quite noticeable, when I am in a parking lot and hit the brakes next to someone, people will give me the look like "what's wrong with your car". I am not positive where this noise is coming from, but my best guess is that it is coming from the right side. The popping seems like something is bound up and then releasing. I can also replicate the noise some times when I initially accelerate. My best guess is that it is being caused from the engine/trans weight shifting, but I am not sure a motor mount can make the popping noise I am getting.

noise in my front end. I know there is a lot of stuff going on there so let me try. Noise is more like a groan not a squeak, tick, not an engine noise or a brake noise. Applying the brakes or turning the wheels does not make a noise. Best way to describe it to me it is like a bad bearing type of noise. The noise is starting to get louder.

Hit a long 4x4 post on the freeway and bent a front rim. Was able to miss most of it but hit it with the right tires. It didn't hit anything under the car that I can tell. Got a new rim and moved the TPMS and tire to the new rim. Back wheel looks ok. Still have a low pressure light. TPMS was lit when I had the bad wheel out of the car but is now out.
Have previously had trouble with another wheel giving a warning when it was only a pound or two low. Checked all the wheels and added a few pounds to each and still have the light.
How do I troubleshoot the TPMS? How long should the batteries last - is this just normal life of the sensors? It's a 2009 model.
Also have some noise and rattles I didn't have before. Not when going straight but when turning and accelerating at the same time. Hoping its just some shields and nothing too serious... I looked and didn't see anything obviously loose so I need to dig into it a bit more.

When I accelerate from stop the left wheel it like makes a "clicking" noise as the car starts accelerating, once in motion there is no "clicking". What might cause it?

My wife's 2006 Honda Accord makes a strange noise when accelerating. The best I can describe it is that it sounds like Woooo. It does not make this sound when driven at a constant speed. The car is in great shape and does not appear to have any mechanical or electrical problems.

We just replaced the inverter pump thinking this was the problem but it is still making noise. System has no air in it. What else can it be?

I can here this squawking under my hood for 30 sec or so after every engine stop, when parking. I purchased the car used with 19,500 Kilometers. This noise has always been there. Is this normal? I believe the noise is from the inverter coolant pump? I don't hear this when the car is running, but then my hearing is not the greatest?
