I noticed a loud whining noise when I started up my 2006 Honda Civic the other day. The whining got progressively worse and then the lights began to flicker, so I turned the car off. Now it won’t even start! The sound was like a belt or something at the front of the engine. What part could have broken to cause all of these problems? How can I get this serviced without it costing me an arm and a leg?
From the way you describe your concern, it leads me to believe that you do have something going on with the belt drive or possibly the charging system. For your safety, the belt drive, which is driven by the crankshaft and is under a great deal of tension, should be looked by a technician so the root cause of the noise can be found. There are multiple items on the belt drive that can make noise such as the A/C compressor, alternator, idler, and belt tensioner. The technician may remove the belt during inspection, check all the pulleys, and manually rotate the engine to see what parts have failed. If a seized component is found, it would need to be replaced. Then the belt(s) can be reinstalled and tested to ensure everything is working properly. If the belt drive system in working order, then the charging system will need to be looked at, testing both the battery and alternator. If the battery or alternator have failed, they would need to be replaced. To have your vehicle inspected, please contact YourMechanic and one of our technicians will be happy to assist.

The battery light is an indication that something in your charging system is not working properly such as a weak battery (usually noticeable with a weak start), a failing alternator or a bad voltage regulator. The whining sound may be the alternator failing which is common when this happens.
There are a number of signs that your car battery is dead. Firstly, listen out for odd noises. Low pitched whining noises and the noise of a cranking engine without it starting are both signs of a dead battery.
Freewheeling. Freewheeling occurs when you crank the engine and simply hear a whining noise without the engine cranking. When this occurs, it means the starter is not engaging with the flywheel. This is a worrying situation which could result in having to replace the whole component.
Power Steering System: A screeching or whining noise while turning at normal speeds could mean an issue resides within the power steering system itself. This complex system consists of hoses, belts, and more that can all fail over time.
Failing alternator bearings:
The alternator has several bearings which allow the alternator`s rotor to spin freely. If these bearings begin to fail, you will notice a loud whining noise, which will increase when you accelerate or the car is under heavier load.
If you ever hear growling or whining noises coming from under the hood, you could have alternator problems, which should be checked out by a professional ASAP. This growling or whining sound happens when the belt that turns the alternator`s pulley becomes misaligned or rubs against the side of the pulley.
If your car won`t start and you hear a `clicking` sound from the engine, it is likely to be a dead battery. If your car won`t start but the headlights work, it is possible that there may be some issues with the starter or engine itself.
If you hear a whining noise from your car`s engine, it may mean much the same thing: there`s a component that`s worn out. If these parts break or wear down entirely, they could cause damage, so hearing a whining sound means that it`s time to schedule a service appointment.
Over time, wear and tear can take a toll on the belt and the pulleys, which often results in that high-pitched chirping sounds when you start the car and accelerate. The most common serpentine belt problems include: Worn/Cracked Serpentine Belt – Serpentine belts have grooves which fit into grooves in the pulleys.
Low Transmission Fluid: For both manual and automatic transmissions, the primary cause for whining when in gear is low transmission fluid. If the fluid is too low, then the internal components of the transmission are not lubricated properly.
The engine of the car makes a whirring sound when accelerating. The more you accelerate, the more the whirring increases. It`s time to get your car in for a checkup! There might be a number of reasons for this, including a bad water pump, low levels of power steering fluid, and a bad air conditioner compressor.
Car Makes Whining Noise When Accelerating
While the transmission is the most likely cause, whining while accelerating can also be caused by low power steering fluid or more serious damage like faulty alternator bearings, a malfunctioning water pump, a broken piston or a bad AC compressor.
Your car can also make a whining sound when the voltage regulator is sending signals to the alternator to charge more than is necessary. If you hear any type of whining or grinding sound that`s a good indication that your alternator needs to be checked.
Using WD-40 to repel water from spark plugs, distributors, alternators, and batteries is a good way to prevent corrosion and keep moisture away. You can also use it to ease the removal of spark plugs, especially if there is any rust or corrosion.
If a faulty alternator fails to keep your battery consistently charged, the fuel injectors may not fire, causing your engine to stall. A dying alternator can lead to a wide range of other electrical issues. Generally speaking, such issues manifest as an inability to perform at normal power.
What happens when alternator stops working while driving? The car tends to slowly lose power if the alternator has gone bad while the car is being driven. You`ll notice the headlights start to dim shortly before the car loses power and dies.
The faster you recognize the signs that your alternator might be going bad, the better off you`ll be, so it pays to know these signs of a faulty alternator: Your car won`t start.
One common culprit for this problem is the crankshaft position sensor, which measures the position and speed of the crankshaft. The computer uses the information from this sensor to know when to fire the spark plugs. If the sensor isn`t working, the spark plugs won`t fire, keeping the engine from starting.
The Car Produces a Clicking Sound Whenever You Turn the Ignition. When you turn the ignition key, and you notice that it makes a ticking noise, that`s a sure sign that the car`s battery is dying. Turning the ignition many times or leaving the car for an hour or so before trying again won`t help.
Short trips drain your car battery, and if you never drive long enough for your alternator to recharge it, your car battery will grow weaker and weaker every time you start the engine. A full recharge protects your car battery. Leaving a car battery drained can damage it and make it more vulnerable to extreme cold.
a. : a prolonged high-pitched cry usually expressive of distress or pain. b. : a sound resembling such a cry. 2.
Should the whining noise of your transmission continue whenever your vehicle is in gear, this can mean there is a problem occurring in your torque converter. Check to see if the noise desists when you shift the vehicle to park or neutral. A constant whining noise when your car is in gear needs professional attention.
A bad battery won`t usually harm your starter or alternator, however, since both of those components get their voltage directly from the battery, if the battery is underperforming, both the alternator`s and starter`s performance will be affected as well.
