Why is my car making noises when accelerating?
If your car makes whining, hissing, grinding, or clicking noises when accelerating, it could signal a minor or serious issue. Our factory-trained team at Coulter Tempe Buick GMC in Tempe, AZ, can quickly identify and fix the problem.
Common Causes
- Exhaust Leak: Cracked manifold, damaged gasket, or broken pipe may cause ticking or blowing sounds. Look for exhaust fumes or a check engine light.
- Intake/Vacuum Leak: Whistling or hissing can reduce acceleration and trigger a flashing check engine light.
- Transmission Issues: Low/contaminated fluid, damaged components, or mounts may cause whining, grinding, or clunking, often at high RPMs.
- CV Joint Damage: Clicking noises when turning or accelerating usually indicate a worn CV joint, common on front-wheel drive vehicles.
If you've ever noticed unusual noises when accelerating—whines, hisses, grinding, or clicking—it's natural to wonder what’s happening under the hood. While some sounds may be minor, others can indicate a serious mechanical issue that requires immediate attention. At Coulter Tempe Buick GMC, our factory-trained service team in Tempe, AZ, helps drivers identify and resolve these noises quickly, keeping your Buick SUV, GMC truck, or crossover running smoothly. This guide walks you through the most common causes of car noises during acceleration and what to do if you hear them.
Why Does My Car Whine When I Accelerate?
There are some emergency issues that our customers immediately consider our service and maintenance team as their only option. When you experience car noises or hear a grinding noise when accelerating, the most important step is to immediately book an appointment with our service team. Here’s why.
Exhaust Leak
Whether it’s a cracked or broken manifold, a torn, ripped, or pinched gasket, or even a cracked, loose, or damaged exhaust pipe, any leak in your vehicle’s exhaust system could cause car noises. If you hear a constant and repetitive “blowing” sound or even a ticking sound that increases in frequency every time you try to accelerate, then you could be dealing with an exhaust leak.
- Cracked or broken manifold
- Ripped or pinched gasket
- Damaged exhaust pipe
You may even be able to smell exhaust fumes, or those fumes may be more prevalent. Finally, exhaust leaks can often trigger a check engine light, so be mindful of the warning signs.
Intake System
Hearing a whistling car noise could indicate an issue with your vehicle’s intake system or could be caused by a vacuum leak. When you hear these hissing car noises, you may also notice your vehicle struggling to accelerate or even appearing as if it's losing power. This is often caused by air entering the engine.
- Check engine light flashing
- Slow acceleration
- Hesitates to accelerate
If you find your check engine light flashing, experience slow acceleration, or your car appears to be unable to accelerate, or it hesitates to accelerate, then book your appointment with our dedicated and experienced service and maintenance team immediately.
Transmission Problems
Whether it’s low transmission fluid, damaged or worn-out transmission components, or even fractured or cracked mounts, transmission problems are one of the most common causes of car noises. The most common noises include constant or infrequent whining. You may also hear a sound as if metal is grinding against each other or even a loud, repetitive clunking sound.
- Low transmission fluid
- Contaminated transmission fluid
- Damaged transmission components
These whining sounds are often accompanied by a higher RPM. If you have a manual transmission, then the whining sounds may fluctuate or appear louder and worse in different gears. Whether it’s a mount failure that is causing excessive vibration, or low or highly dirty transmission fluid, our seasoned mechanics and incredible diagnostic team will assess the problem and have you back on the road in no time.
Damaged or Worn Constant Velocity Joint (CV)
Among all the possible reasons you may experience car noises, this might be the least understood or known by customers. Think of a CV joint as that all-important part of your vehicle’s axle that allows the axle to provide power to your vehicle’s wheels. When damaged or cracked, a CV joint can make what sounds like a clicking noise. This clicking noise increases when you turn your vehicle or even when you accelerate.
- Cracked CV Joint
- Repetitive clicking noise
- Prevalent when turning or accelerating
This problem is very common on front-wheel drive cars. Do not ignore these sounds. A damaged CV joint can quickly escalate into a more expensive problem, so book your appointment immediately with our service team if you believe this is a possible cause of the car noises.
