why does my car make a noise when i accelerate

Johannesburg - Experts are always warning parents to listen to their children so as to pick up on subtleties which could be indicating a far more serious problem. Les Mc Master, chairman of the Motor Industry Workshop Association (
), says it s the same with cars - ignore your car s moans and groans at your own peril. MIWA says: Many car owners drive in blissful ignorance of unusual sounds for fear of these being something major which will cost a fortune to repair. READ: Cars can make a cacophony of sounds. While some sounds are normal and many harmless, some need immediate attention, according to MIWA. Mc Master adds: Where on the car the sound is coming from can sometimes be deceiving as to what the actual problem is, but it is an important indicator of how soon you should consult a reputable workshop to check it out. Have you heard any strange sounds from your vehicle? Let us know via, or. Call your local independent workshop owner when you hear: List by MIWA 1. Grinding noise from the engine : This sound might not necessarily be your engine. It could be your front brakes. It's important to resolve the issue as soon as possible at a workshop/garage. 2.


Any sound when turning a corner : This is likely to be connected to your steering column which could be damaged. 3. Grinding gears: The clutch is either worn or needs to be adjusted. It can also indicate a more serious problem with the transmission. 4. Knocking: If it s a ' knocking' noise from deep within the engine, it s usually not a good sign. It could be your rod bearings which are worn out or loose and on the verge of failure. Contact a workshop immediately and have the noise diagnosed. 5. A s quealing sound when accelerate: You won t miss this high-pitched noise and it s more than likely your fan belt which is loose. It may also be worn through, in this case it would have to be replaced. 6. Hissing under the bonnet: You d usually hear this when you switch the car off. It could be an oil or coolant that is leaking onto a heated engine part or the engine could be overheating. 7. Loud bang while driving: If your car is backfiring it means the air/fuel mixture is too rich or the catalytic converter isn t doing its job. 8. Rattling under the car: Your exhaust system or brake pads could be loose. 9.


Roaring as you accelerate: Check your exhaust system first as it could be damaged. Transmission issues could also be to blame. 10. Scraping and grinding when you brake: Your brake pads need to be replaced because they re now metal on metal and every time you hit the brakes you re doing damage to your car! READ: Mc Master concludes: "So, cars are very much like humans, in general. They re going to whine and moan and act up when something s wrong. "Our best advice to car owners is don t bury your head in the sand when your car is making a strange sound; get it checked out before it becomes a major headache. "Never use higher-octane fuel than is specified for your car, follow specifications for things like oil and tyre pressure and ensure your car is regularly serviced and maintained. If in doubt contact a MIWA workshop near you. Becoming agitated when you first notice you car makes noise when accelerating will not diagnose or solve the problem any sooner than if you remain calm and collected. Choosing to be nonreactive in such a situation allows you to better observe the symptoms, so you can fully describe the issue to your mechanic or troubleshoot on your own.


In this article, Method 1 covers how to deal with chirping or squealing upon acceleration. Method 2 describes what to do when your car roars with greater speed. Usually, chirping or squealing noises when accelerating indicate a slipped or loose belt. Less frequently, it could point to a misalignment in the drive pulley of the water pump or another accessory. Step 1 of 4: Start your carвs engine. Make sure the vehicle is in Park if it has an automatic transmission, or shift into Neutral and engage the emergency brake if it has a manual transmission. Step 2 of 4: Ask a friend to press and release the accelerator. That way, you can audibly and visually observe what happens from outside the vehicle. Step 3 of 4: Open the hood. Then, listen and watch for where the chirping or squealing noise originates. When you have finished, make notes of what you heard and saw. Close the hood, stop the engine, and contact a mechanic. Step 4 of 4: Describe your observations. Use concise and precise language when speaking to a service technician, which will help narrow the potential causes of the chirping or squealing noise when accelerating.


When you hear a roaring noise at greater speeds, it signals a greater issue than small squeals or chirps. You can help diagnose the cause by pinpointing the source of the roar with a few simple steps. Step 1 of 3: Rev the engine. Do this with the car at a stop or parked by pressing the accelerator pedal. Step 2 of 3: Listen attentively. Specifically, listen for the roaring noise, and note if it happens when the car is not moving. Step 3 of 3: Contact a mechanic. Mention if the roar occurs only when moving or both when moving and parked. If your car roars with just revving the engine, the problem likely lies in the exhaust system. If the roaring only happens when actually driving, the transmission in an automatic vehicle or clutch in a standard may be the culprit and in need of repair. Whenever your car begins to make a noise it did not make previously, it is wise to calmly gather as much information about the systems as you can and seek help from a service technician. Prompt attention to the issue may prevent greater problems from arising, and your keen observations can save labor costs in diagnostics.
