Why is my GMC Yukon Making Noise When Accelerating – 12 Problems We Encounter

As the introduction mentions, your vehicle makes different noises due to some factors. Especially the faulty things or attachments that disturb your driving time. Anyway, let’s read further to know how your car gets into trouble and how we should fix the car from such terrible sounds.

Transmission Problem

The first issue we want to discuss is the transmission problem on your GMC Yukon. Whenever you hear a low-pitched humming noise, make sure you check the transmission.

Uneven Tire Wear

How does listening to an automobile making a loud noise while driving down the highway feel? The humming noise indicates a risk for the vehicle that needs to be resolved as soon as possible. 

While moving a 2015 GMC, some users reported experiencing weird noises. They checked countless things, but they failed to notice that the trouble was that uneven tire tread wear had the potential to produce noise.

Irregular tire wear is typically affected by mismatched wheels, poor wheel alignment, over or maybe under-inflated tires, and damaged suspension or steering elements. Therefore, you have to replace damaged shock absorbers or other suspension parts to eliminate the noise, but never use tires of any low-quality brands.

Big Tread Block Tires

The kind of tire you use can sometimes be a critical problem. Particularly if you hear the noise after installing new tires on the rims. However, tires with a big tread block design are recognized to be loud on the roadway.

You may have also observed strange noises in winter or off-road tires at high speeds due to how air flows through extreme tread patterns. As a result, tire selection should be prioritized.

Malfunctioning Alternator

Why is my car making a whining sound when I accelerate? The alternator generally has many bearings that allow the alternator’s rotor to spin securely. Note that the alternator is connected to the battery lights. As a result, a problem with the alternator will result in your battery not being charged. But if the alternator makes noise under load, ensure you understand the carrying limitation.

The vehicle alternator is also linked to the serpentine belt, which turns while the engine runs. So, repairing or replacing the alternator can be the ultimate solution.

Clutch System Trouble

Sometimes, the noise you don’t want to hear from your vehicle is caused by the clutch system due to manual transmission. Have you checked whether your GMC Yukon clutch release bearings are worn?

It would be much better to replace the clutch system after 80k miles or go to the mechanic to address the issue. Before that, check to see if you have problems shifting gears or feeling resistance in the clutch pedal, which could be heavier or non-existent. Remember that replacing the clutch will cost approximately $1000 and $1300.

Problem With Turbocharger

GMC Yukon whining noise when accelerating?  Diagnose your turbocharger or what we call the supercharger. The limited power steering fluid is likely causing some unpleasant noises underneath your engine. Such a problem should be resolved immediately, or the engine may become blocked.

Bearings in Your Transmission

Some users have complained that GMC Yukon humming sounds coming from inside, where the bearings are to blame. The problem is with the rolling sections and bearings that influence the power transmission to other areas of your automobile.

Also, the wheel bearings in each wheel hub frequently generate noise. A failed wheel bearing is more likely to generate a roaring sound or a whine when driving.

Water Pump Issue

You may have heard the barking of dogs or squeaking noises. The GMC Yukon may be making such noises. It often occurs when the water pump fails. It also sounds like metal hitting metal. It has a deep tone, and fixing or replacing it will cost much money. The estimated replacement cost is between $711 and $843.

Serpentine Belt Issue

In general, the GMC serpentine Belt rotates using the crankshaft’s motion. However, damaged belt grooves and smoothness reduce gripping power. Eventually, such situations result in a whining sound as you accelerate the Yukon.

Additionally, the whining sound is comparable to chipping or chirping. A bowed or loose pulley might enable the serpentine belt to produce sound. Therefore, we recommend replacing the belt.

Air Leakage

Air leaking from the air supply system often lets your truck whine when accelerating.  You may have a hole in your connectors or air hoses, which is the main culprit.  As a result, check the airflow system from the filter to the engine to identify the cause of such an accelerating note.

Power steering Pump and Low Fluid Level

Recently, an issue happened in that the 2003 Yukon XL 2500 emitted a grinding noise when accelerating, but he couldn’t figure out what was wrong with the car. The truck in hand is a 2003 Yukon XL 2500 4WD with 63k miles.

Such a problem could arise if the transfer case fluid has not been transferred. Low transmission fluid is the most common cause of whining or friction while in gear in both manual and automatic transmissions.

In addition, a failed power steering pump causes the automobile to produce noise as you accelerate. Fill it back to the manufacturer’s fill line whenever the fluid level is low. Test the sounds to see if it gets louder when you spin the steering wheel on your Yukon.

Grounding Issue Makes Stereo or Radio Noise

Also, the radio or stereo may also emit a whining noise, which is common for alternator whining. A weak ground wire often causes the alternator to whine at the radio.

Faulty Torque Converter

When starting, a malfunction with the GMC Yukon torque converter might generate a whining sound. As a result, checking the transmission fluid is a smart starting point. If you find any metal flakes, repairing them is crucial.
