Humming while driving your Nissan Altima at motorway or freeway speeds can be risky in addition to being annoying. A humming noise is a sign that your Altima has an underlying issue that has to be fixed right away for your safety and comfort while driving.
Bad wheel bearings, uneven tire wear, and using tires with huge tread blocks are the most frequent reasons of humming noise in Nissan Altima at high speeds. Transmission failure is a less frequent reason.

Johnny R. There are several potential causes, including a splash shield rubbing on the wheel, a brake backing plate or shield that is loose or rubbing, a bad wheel bearing, a defective CV (constant velocity joint), a loose bracket, a stuck brake caliper, a worn internal gear or bearing in the transmission or differential, etc. To make sure the noise is coming from the driven wheel/axle area and not the engine compartment, you may jack up the front of the car, rest it on stands safely, and cautiously try running in gear. If the left front wheel is making noise, it would be a good idea to remove the wheel to check for any obvious signs of wear, damage, or rubbing. Have a reputable local shop take a look and provide a repair quote if you are unfamiliar with or unwilling to make the diagnosis yourself. Good fortune. I hope this was useful; please let me know if it was by clicking the “helpful” button.
I looked through various forums with a similar problem, and I found that if the noise only occurs when the car is moving and it has a CVT transmission, that might be the problem. If a noise can be heard when the car is in park and gets louder as the engine revs rise, it may be a water pump bearing, pulley, belt, or anything similar that has to be replaced. However, even a skilled ear cannot completely rule out some of the aforementioned possibilities. You should probably bring the car in so that a reputable local shop or transmission shop can diagnose the problem.
Good day, Donny. I experience the same issue. The identical spot where your car creates the noise also affects my 2008 Altima. Online searches for solutions have failed to identify the true issue. I changed the wheel hub bearing, and the issue was resolved. I’m awaiting the delivery of my CV half shaft, but I’m worried that won’t help either.

all ok. I first noticed a loud road noise coming from the front of the automobile a few months ago. My friend’s 2005 Nissan Altima reported hearing a noise and needing new bearings. I brought my car to Nissan, who found no bearing issues. I recently purchased new tires because I believed the noise to be from the road and it was past due for new tires. I put $50,000 on them. Clearly, it was not the issue. The noise is still present. When I’m driving, the gas pedal kind of feels harsh. Any thoughts?
Why is the whining sound coming from my Nissan Altima?
Low Transmission Fluid: Low transmission fluid is the main cause of whining when in gear for both manual and automatic transmissions. The internal parts of the transmission are improperly lubricated if the fluid level is too low. Friction between those pieces is what you’re hearing, and it can cause a great deal of harm. It is advisable to look for transmission fluid leaks if the fluid level is low.
As previously noted, some transmissions naturally whine, and this is quite acceptable. The whine may be more apparent in first gear, third gear, or another gear, depending on the make and type of the vehicle. Knowing the typical sound of your transmission is your best line of defense in this situation.
Flywheel or Clutch Wear: If you have a manual transmission, it’s possible that your flywheel or clutch needs to be resurfaced or that your clutch is worn out. It’s possible to hear whining, grinding, and other strange noises when these parts start to deteriorate.
If you hear the whining even while the clutch is not engaged, there’s a probability the throw out bearing is to blame. Instead of shifting into gear without applying any clutch pressure, noise from this bearing is more frequently heard while applying the clutch.
Bad input shaft bearing: When this internal bearing inside the transmission casing starts to fail, it might produce a whining sound.
Although each wheel hub contains a wheel bearing, a bad wheel bearing can cause a sound to travel and appear to originate from the transmission. Although a whine may be produced while driving, a failed wheel bearing is more likely to make a roaring sound.
How do I get my car to stop buzzing?
- Connecting wires loosely.
- Take Ground Loop Noise away.
- Cut down on electromagnetic interference.
- Use RCA cables of the highest caliber.
- Use dependable power cords.
What may make my car hum when I’m driving?
Possible causes include a number of things. Make a note of the noise’s occurrence time so you can assist your mechanic with problem diagnosis. A humming noise coming from your car may indicate that the differential requires lubrication, the transmission needs repair, or the wheel bearings or universal joints need to be replaced.
What to do: Pay close attention to what transpires just before and after your car makes the noise. Give your mechanic as much information as you can; without a careful, expert inspection, it may be challenging to pinpoint the issue. Without having a mechanic examine your car, don’t let the noises persist.
Why does my car seem to be humming when I go fast?
You hear a low-pitched hum while driving. The noise increases in volume as you speed up and may even resemble an airplane taking off, but at a certain speed, the volume stays constant. The noise increases as you turn, but if you turn the opposite direction, it stops.
What it might mean: The noise is probably coming from a wheel bearing. It’s frequently misidentified as an engine noise, but you can tell by keeping an eye on your RPM gauge. RPM and speed meters increase as you accelerate. Watch the RPM gauge fall as you coast at a fixed speed while releasing the gas pedal. If the noise persists, the engine is unquestionably not the source.
Which model year of the Nissan Altima suffers transmission issues?
Poor CVT performance and failure also occur frequently in the preceding Nissan Altima generation (2007 to 2012). Nissan extended the powertrain warranty on the Altima (only 2007–2010 models) to cover CVT difficulties for up to 10 years or 120,000 miles as a result of these concerns.
How much does a Nissan Altima transmission replacement cost?
Cost of Nissan Altima transmission Depending on the car, a new Nissan Altima transmission could cost over $3,500, while less fancy transmission treatments like fluid changes and transmission fluid flushes can sometimes cost less than $150.
What is the source of alternator whine?
Alternator whining is the main source of noise in the automotive audio environment. A difference in electrical potential (voltage) between two places is what causes alternator whining. It’s typically brought on by a subpar ground connection. The amp, the head unit, and any intermediate parts like crossovers and equalizers are the main offenders. Basically, anything that comes in contact with the low level audio signal (from RCA cables). Finding the noise entrance and re-grounding that component usually solves the problem.
A wheel bearing makes what kind of noise?
A faulty wheel bearing will typically make a cyclical chirping, squealing, or growling noise. If the sound fluctuates proportionally to the speed of the vehicle, this is another sign that it is caused by the wheel bearings. With each turn, the sound may increase worse or it may briefly stop.
Can a whining noise be caused by low transmission fluid?
Low Transmission Fluid: Low transmission fluid is the main cause of whining when in gear for both manual and automatic transmissions. The internal parts of the transmission are improperly lubricated if the fluid level is too low. Friction between those pieces is what you’re actually hearing, and it can seriously harm your vehicle. It is advisable to look for transmission fluid leaks if the fluid level is low.
Flywheel or Clutch Wear: If you have a manual transmission, it’s possible that your flywheel or clutch needs to be resurfaced or that your clutch is worn out. It’s possible to hear whining, grinding, and other strange noises when these parts start to deteriorate.
There is a possibility that the whine is coming from the throw out bearing if you hear it when the clutch is disengaged. However, it is more frequent to hear noise from this bearing when applying the clutch than when the vehicle is in gear with the clutch pedal down.
Although each wheel hub contains a wheel bearing, a bad wheel bearing can cause a sound to travel and appear to be coming from the transmission. Although a whine may be produced while driving, a failed wheel bearing is more likely to make a roaring sound.

How may an alternator whining be eliminated?
Engine noise or alternator whine is the noise sent through the power and ground wires attached to your receiver. You can hear a whining or clicking sounds if the source of the problem is engine noise. Usually, the pitch will change as the engine speed does.
If so, you can reduce the issue by adding an alternator noise filter to the power line that runs between the battery and the alternator. To reduce signal interference, you can also attach a noise filter to the receiver’s power lead (for example, an S15A (15-amp, 250-watt) or S25A (25-amp, 350-watt) filter from American International). However, a weak or inconsistent ground connection is the most frequent cause of alternator noise. Regarding electrical system noise, see the section below.
The alternator and battery are connected in line, and an alternator noise suppressor can lessen the high-pitched whining noise that varies with engine RPMs.
