5 Easy Solutions For honda accord making whining noise Problems  

When one or more crucial internal structures fail, your honda accord makes whining noises. Therefore, this noise almost always indicates that you need a repair or replacement. Let’s know about them in more detail.

1. Replace Damaged Alternator

The alternator in your honda accord turns chemical energy from combustion into electrical energy. Thus, it provides power to all the electrical components in your car and maintains the charge of your car’s battery.

Due to time and stress, the alternator can become significantly damaged, and its bearings wear out.

Damaged bearings often cause high pitch whines from your alternator. So, this is often the first component your car- professional checks out when there’s a noise complaint. 

You might have to tighten the alternator or replace it. The alternator replacement cost for a honda accord is usually around 500-700$.

Continuing with a damaged alternator poses more problems than just a whining noise. For example, you will be at risk of a complete battery shutdown in the middle of a highway.

2. Fix Serpentine Belt issues

One of the major reasons for your honda accord’s whining noises is the serpentine belt. It’s also known as the drive belt. This is a one-piece continuous belt that drives various peripheral components in your honda accord. 

Devices that connect to the serpentine belt include the AC compressor, Air pump, power steering pump, alternator, etc.

The drive belt’s material is mostly rubber. So naturally, it will lose its consistency and wear out after you have driven the car for a significant amount of time. 

And this is when the belt starts making high pitch noises that sound like whining. Here, your best option is to replace the belt. This will cost you around 350$ or upwards.

There might be some other associated symptoms when the whining noise of your honda accord occurs due to a drive belt event.

For instance, overheating can become a regular issue. You can also encounter issues with the AC and power steering. A damaged drive belt also affects the alternator’s performance. Thus you can experience issues with the battery charge.

3. Check Power Steering System

When you hear a whining noise while turning the car, the problem usually lies within the power steering system. There are a lot of probable issues that might occur in the power steering to cause this.

Often, it is the power steering belt that has worn out or lost its tightness. Sometimes you will find the belt is all good. In that case, you should think of the power steering system fluid. Low fluid is a major reason for whining noises while turning a car.

So, check the fluid level, and if it’s lower than normal, you have most likely found the source of your problem. Here replenishing the levels will solve your problem.

4. Repair the Transmission System

Another instance of whining noise occurs when you accelerate the car. Here, your honda accord’s transmission is the first system you should consider. 

Maybe some of the gears have taken too much damage. Or in some cases, leakage of transmission fluid is to blame.

Although the transmission system is the first thing to check, there are many other reasons for the whining noise during acceleration. Sometimes, it might occur because of a faulty AC compressor or a malfunctioning water pump.

Broken pistons, bad bearings, malfunctioning water pumps, and other reasons can also contribute to this whining noise. 

It is best to consider all these reasons before replacing your transmission system, which takes a whopping 3000-4000$ out of your pocket.  

5. Fix Oil leakages

You are stuck in a traffic jam with your honda accord, and the engine is running. Suddenly, you notice a whining noise from your car. 

Of course, a car that has been on the road for a while will make some kind of noise when you are idling. However,  a whining noise is easily distinguishable from your usual car noises.

The most probable cause for a honda accord making whining noises while idling is oil problems. 

Unless you forgot to refill your fuel tank, which is unlikely for regular drivers, the reason might be leakage or blocked valves. Typically, an engine leak inspection will cost you around 100$.
