Your car can vibrate, shake, and create various types of noises for different reasons. If it particularly happens when you accelerate the engine, you can pin down the problems on common failures of several components. Knowing about them will help you with quick diagnosis and finding the correct fix before it gets worse.
A bad torque converter could be the origin of rattling sound when accelerating at low speed. If this happens, you should take the vehicle to a repair shop as soon as possible.
The motor mount on the passenger side could be another obvious culprit. A ruptured mount will leak fluid everywhere. So, if you see dark lines of dripping oil underneath or on the frame next to the side mount, take it to a mechanic.
Reasons Your Car is Making Noise when Accelerating
You will need to have it diagnosed by a professional in that case. These components act as a thermo-reflective barrier between the exhaust system and other parts including gas tank, fuel lines, and the cabin of a car.
When they are loose or broken, they fail to completely block the heat transfer to these key areas. As a result, you will hear frightening rattles at higher speeds. You have to inspect the exhaust system to find out if heat shields are causing rattling noise in car when accelerating. However, do it only when the engine is off for several hours.
Q: Loud roaring sound from engine when accelerating
The exhaust pipe and some other parts remain hot even after hours of switching the engine off. The speed of these pulleys escalates with the engine speed.
If they are slightly bent or loose, the metal-on-metal contact will create terrifying rattling sound when accelerating. Open the hood and inspect the V-belts when the engine is off and running. If a pulley is bad, the belt will show damage in the form of frayed sides. The rattling noise appears when you start speeding up from 0 to maybe 30 or 40 mph and then disappear after car speed surpasses 40 mph. In another circumstance, when your automobile is running at low speed the noise keeping coming out of car engine.
Moreover, you have the feeling that your car is holding back by something indefinable. What have you done in that situation? The culprit of rattling sound when accelerating mainly derives from car engine.

Why does this happen and how to get rid of this embarrassing problem? With frequent use over time, many car components wear out and start showing issues. A car that makes such a weird noise at the time of acceleration, will be fine at a set speed. It is actually challenging to find the root cause of whining noise when accelerating but these common causes will give you the heads-up. You should do a thorough transmission check-up when the car starts making a grousing sound when speeding up.
It could happen because of low transmission fluid level or worn out gears. Low level of fluid can cause all sorts of problems, and bizarre noises are the first to start with. Spotting this problem and refilling the fluid can save you plenty of money down the road. On the other hand, if the noise does not begin unless the vehicle is in motion, there must be issues with one or more gears and bearings.
Planetary gear sets will create a whining sound when they are worn out but only when the car starts moving. Repair or change the gear components if they are damaged. A loose steering belt could be the culprit behind a whining noise when accelerating. When it happens, the sound will occur when you are turning the steering wheels.
Tightening the belt will solve this issue. A leak in the power steering system can start that annoying whining noise. If you discover drips under your car or a visible drop in the level of power steering fluid, there must be a leak. Look into the steering rack or gear because these are the places where the leak is likely to occur than in the pump. You can replace the damaged or leaked parts and refill the fluid to fix the problem.
The easy fix is to add a liquid stop-leak solution to the reservoir. There are plenty of good-quality products in the market that offers a simple, quick, and inexpensive solution than replacing components. After adding the stop-leak mixture, fill up the reservoir with power steering fluid. The rising noise in the car can indicate an engine problem too.
The engine has a complicated mechanism and it is better to go to a mechanic for its diagnosis. But, you should do that only after being sure that the trouble is with the engine, not with the transmission. Shift the gear into the Neutral mode and crank the engine gently.
If the noises seem to have a relation with the engine speed, the engine is in trouble. If there is no sound when the car is not in gear, the engine is unlikely to be the source of the complication.I have a Toyota Camry with approximatelymiles on it. I had started to notice or thought I did! Today as I was driving to work, upon acceleratation after a stop light, the engine started to be REALLY loud, almost like a motorcycle engine.
Additionally, the gas pedal started to vibrate a bit. Otherwise, the car runs fine; there is no shaking, no other noises, no funny smell as far as I can telland no indicator lights have come on.
Does anyone know what might have caused this, or how much it might cost to fix it? First—is there a tachometer on the dashboard? If yes, does the tach now register higher RPMs when accelerating than it did previously? If the RPMs are higher than they used to be at a given speed, then it is likely that your transmission is about to die if you have an automatic transor your clutch is slipping badly if you have a manual trans. If it is an automatic transmission, when was the last time that the trans fluid and filter was changed?
If you did not do this, then your transmission was living on borrowed time already, even before the appearance of any strange symptoms. That would be considerably cheaper than transmission overhaul, but since you report gas pedal vibration, I tend to think that this is more likely to be a transmission problem. When the friction surfaces in the transmission are worn away, a shuddering sensation is frequently felt upon acceleration, and many people interpret this as an engine problem, even though it is originating in the failing transmission.
I drove carefully to the repair shop because I was worried about damaging the car more, but I could have accelerated faster if I had wanted to. I had an oil change last October, and they checked the transmission fluid then and determined it was fine. They have not been shy about suggesting things on the car to fix. Perhaps it is a leak in transmission fluid? Any possibility that this could be due to a transmission fluid leak? If so, have I done irreversable harm to the car by not catching it sooner?
Diagnosing Whining Noise When Accelerating
Or would it be as simple as fixing the leak and replacing the fluid? If the car was driven for more than a relatively short distance with a low level of trans fluid, you could have done some very expensive damage to it.BELT NOISE - Causes & Solutions (by Dayco)
Rather than paying to fix a leak on a transmission that is going to fail next month, I would suggest that you have a transmission shop examine the trans. Hopefully you will get some good news regarding the transmission, but in any event, you need to know the truth about the trans before investing even one cent in it. Transmission, or any other chain trans shop unless you want to be told that you need a new transmission—whether you really do or not.
You need to use an independent trans shop that has been in business for at least 3 years if you are going to get an honest diagnosis, a fair price, and good workmanship.
A chain trans shop will overcharge you for substandard, possibly unnecessary work. I am planning on getting a second opinion at another shop, in part because this shop will not put in after-market parts in the car, which could really bring down the repair cost.
What do you think about their diagnosis? Or about the price? Well, an exhaust problem is better than a trans problem! However, that estimate sounds VERY high to me, and it would definitely give me pause regarding a vehicle that is already 18 years old.
As to getting another 5 years out of it, I am skeptical.Are you experiencing whining noise when accelerating your car to high RPM speeds? This seems to be a common problem with many cars. In this article, I present some of the possible causes of whining noise while accelerating. Is a whining noise while accelerating, disturbing your peaceful meditative state at the driving wheel? Whining noise while accelerating seems to be one of the most commonly faced and most discussed problems on automobile forums worldwide.
Some report a whining noise from engine, some report it to come from the front right or front left and some are plain clueless about it. What makes the whining even more mysterious is the fact that it occurs only at high engine RPM or while accelerating.
Would you like to write for us? Well, we're looking for good writers who want to spread the word. Get in touch with us and we'll talk Friction and vibration are two factors that come into play at high car speeds. With a plethora of operational moving parts, figuring out the culprit contributing to the car making whining noise is difficult even for experienced car drivers. One way out is to check for all likely possibilities, one by one. To figure out why a car makes whining noise while accelerating, make a list of all possible causes and eliminate through investigation, till you can narrow down to a single one.
In the next section, I provide a list of possible causes of whining noise during acceleration, that I discovered from various automobile forums and experienced auto mechanics. Possible Causes I list out the various reasons why your car can become a whiner at high acceleration speeds. One clue is to figure out what parts of a car come into play at high acceleration speeds.
Here are some hints. Transmission Problems One of the prime reasons for whining noise may be friction caused in the car transmission mechanism. The reasons for this might be worn out gears and low transmission fluid levels.There are noises that are normal on acceleration. The best way to know if the noise is normal is simply if you have heard the noise before.
You have probably driven, or at least ridden in cars for years. If the car seems to be excessively loud in general, this is an indication of a problem.
There are a number of reasons that a car will make extra noise, all of which are the symptom of a bigger underlying issue. There are a lot of things that can cause a noise when accelerating. The first is belt noise. This noise most often happens when you first begin to accelerate, and sometimes when turning. Belt noise can mean the belt is worn or loose.
Belt noise can also come when one of the pulleys the belt is riding on starts to fail. When the belt no longer moves smoothly along the pulleys, it makes a noise when the car is accelerating. The other noise you might be accustomed to is that of a loud exhaust system.
The exhaust system carries the exhaust gases from the front of the car to the rear. A leak anywhere in this system makes a rather distinct rumbling noise.
This noise is more noticeable on acceleration because the engine is working harder, making the noise louder. With an exhaust leak, the muffling of the noise is cut short, making the noise louder. Worn or otherwise compromised drive belts are a common cause of noises when accelerating. There are also some more technical causes to point out, without getting into too much jargon.
Any of the components in the drivetrain can wear and start to make noise. The drivetrain is essentially what makes your car go, and all of these parts move when your car is moving. This in turn makes audible noises. Like exhaust noises, these noises are more noticeable when accelerating because the car is working harder to get you up to speed.
The engine itself can also be the cause of noises when accelerating.I can hear a loud roaring sound coming from the engine as the car accelerates. The Check Engine light also comes on. It sounds like you have an exhaust leak. An exhaust leak can cause a Check Engine Light. It will give the O2 sensors a false reading. The exhaust runs nearly the length of the car and consists of two catalytic converters, three mufflers and piping. It can leak anywhere and usually leaks due to rust.
Only the broken section needs replacingbut it will need to be inspected to see what needs replaced, and what parts can still be used. Replacement exhaust is a lower quality than factory.
Factory exhaust is very expensive when it is available. If it remains on after a week, then have it diagnosed. Q: Loud roaring sound from engine when accelerating asked by Una N.

Regardless of the fault, you must identify and correct the problem quickly -- otherwise your problem will get worse. Heat shields are a common source of rattling. These shields prevent heat transfer into the cabin of the vehicle, the fuel lines and even the gas tank.
Regardless of what they protect, when they come loose, they can make some scary rattles when the engine is under load. Never attempt to inspect or repair the exhaust system when the engine is running or has been recently running. Portions of the exhaust can remain hot for hours after an engine has been shut off. Inspect your exhaust system from front to back. Heat shields are flexible but are normally mounted so that they cannot move or shift position.
Inspect each heat shield for damage, looseness or wear from contact with another metal surface. Bend or shape any of them, as needed, to prevent metal-on-metal contact. If you fabricate your own, weld or mount the shield so that there is a small air gap between the exhaust and the shield, as well as between the shield and whatever it protects. As engine speed increases so does the speed of every pulley in the accessory drive system. Loose or even slightly bent pulleys can sound like death at higher speeds, as metal-on-metal contact occurs thousands of times per minute.
The easiest way to determine if a bad pulley is the cause of your rattling, is to visually inspect the belt as the engine is running, and when the engine is turned off. Do not let your clothing, hair or jewelry come into contact with the belt while the engine is running.
With the hood open, you may be able to hear the noise at idle and pinpoint the general location. When the engine is running, a loose pulley will cause the belt to wobble back and forth a little bit. The belt itself will also exhibit damage in the form of frayed sides from being pulled against the sides of the other pulleys. If you think the rattle is in the accessory drive system, remove the belt and spin each pulley by hand.
Try wiggling the pulleys to see if you get any movement. Replace any pulley that is loose or wobbles. Ignition pinging is often interpreted as a rattle at first because of the metal-on-metal noise it creates, and it is commonly heard only on acceleration. Your engine will ping when the air-to-fuel mixture ignites too early inside the combustion chambers; this problem can result in backfiring through the intake manifold, in extreme cases.
If you own a newer vehicle, ignition pinging occurs if you use fuel with too low of an octane rating or if you got stale gas on your last fill.
