Car makes noise only in the morning
Car is parked in garage at night. When I start car every morning and put car in reverse or drive it makes a loud clicking metal type noise for about 30 seconds to a minute. When the noises stops, the car seems normal. The noise seems like it is coming from the under the hood on the passenger side of my car. I only seem to have this problem first thing in the morning or when the car hasn't been driven for many hours. Any idea what could be causing this? Thanks!
My car has 66000 miles.
My car has an automatic transmission.
Experienced mechanics share their insights in answering this question :
Hello. Thank you for writing in. When the vehicle sits for an extended period of time, the oil collects at the bottom of the engine due to gravity. This causes the engine and components in which the oil lubricates to run dry. There is no problem with this while the engine is off, and every car does this. Now when the vehicle turns on, the engine will need a moment to circulate that oil throughout the engine. Once the oil becomes warm enough to be the viscosity in which the engine desires, and everything has had a moment to become lubricated again, there should not be any more noises coming from the valves. If this is a new noise or it is irritating to you, you can attempt to change your oil or maybe even change the type of oil that you were using. The noise is simply the engine not having oil when it first starts up. But this is normal.

It might be a battery or alternator problem.
If the source of the clicking is electrical, the starter (a small motor energized by the battery that gets the engine running) doesn`t have enough juice to stay powered. So instead, it rapidly turns on and off and produces a clicking noise!
The most common reasons a Hyundai Tucson engine makes a ticking noise are low oil level or pressure, an issue with the ignition system, or an exhaust leak.
Low Oil or Oil Pressure
An engine with low oil or low oil pressure can make a ticking noise due to a lack of lubrication. If you are low on oil, it may indicate either oil consumption or an oil leak, both of which should be addressed as soon as possible.
Most often, a ticking noise in a Hyundai Elantra when accelerating is caused by low oil pressure, a low oil level, an ignition system problem, or an exhaust leak.
Usually a rapid clicking noise is a good indication that your starter motor isn`t getting enough electrical current to engage – basically your solenoid is trying to engage but can`t make the connection.
Cold weather can exacerbate underlying car problems, so you may begin to hear squeaks, squeals and other funny noises you haven`t heard before. These noises may be caused by the engine belt, the serpentine belt, the air conditioning compressor or a power steering pump.
When the timing belt starts to wear out, it may create a ticking sound inside the motor. This warning sign may also be an indication of low oil pressure or the engine not having the proper amount of lubrication.
The ticking sound is commonly caused by opening and closing valves or rocking arms. This could mean the car is low on oil or there is a problem with the oil delivery system that needs to be repaired. The noise can go away once the parts are properly lubricated.
A ticking noise is generally the result of a lack of lubrication where the moving components do not get sufficient oil for their seamless movement. But unlike other engine noises, a ticking or tapping sound especially after an oil change cannot be traced back to a specific problem.
That dreaded clicking noise can usually be traced to the battery, and the fix could be as simple as a jump-start or tightening a cable. Just one click, though, probably means the fault lies with the starter motor (more on that later).
When this happens, this can be due to one of four issues with your car. The engine itself may be suffering damage to the valves, bearings, or pistons, which may be the very source of such noises. The exhaust system may also be experiencing similar damage with parts like the header pipe, muffler, or resonator.
If your car`s transmission is poorly lubricated, metal components inside of it will grind against one another. This can lead to a rattling sound as gears wear down inside the transmission.
Rattling noises when accelerating your car can be caused by many things, including worn-out suspension components, a broken or loose heat shield, bad motor mounts, low transmission fluid, and faulty engine components.
There is a rattling sound. A lax timing chain, or worse, a broken timing chain with loose parts within the engine, will produce a rattling sound when your car is idling. This rattling sound is typically most prominent while the engine heats up and disappears after some time.
Should your vehicle`s engine run low on engine oil it could cause it to make a loud “ticking or tapping” noise. This noise is caused by an insufficient amount oil being pumped into the top part of the engine. A simple check of the engine oil level will help you determine if the system is low.
Lifter Ticking
If a lifter goes flat, or won`t hold pressure, you`ll likely hear it begin to make noise. Often, a lifter tick will be most prevalent as soon as you start the engine, and may get quieter or disappear completely as the engine warms up. You may also notice the sound is more prevalent at idle.
The clicking sound that`s heard on start-up is nothing more than the fuel injectors pulsing on and off under the high pressures from the mechanical pump. Like the ticking sound, it also will decrease in intensity as the engine warms.
The starter relay makes a clicking sound, but the engine does not rotate, which indicates that the starter motor is not receiving enough current from the relay. This may also be a sign of low or exhausted battery power. Only when it transmits enough current to the starter, the relay starts to work.
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.
Knocking, Popping, or Banging
A car engine noise that sounds like popping can indicate several problems, including worn or dirty spark plugs, a clogged fuel filter or dirty air filter, bad ignition wires, or a problem with the distributor cap or rotor.
A loud noise coming from your vehicle when you accelerate, particularly one that sounds similar to a lawn mower is most likely due to an exhaust system leak.
When your engine is lubricated properly with fresh oil, it should run fairly quietly. As the oil ages and it loses its ability to lubricate the components, the parts will start to move harder against one another causing friction and grinding. These rattling, rumbling, and knocking noises will be hard to miss.

My car makes a really annoying noise and sometimes dies right after
ANSWER : Hi there. From the description you have provided your vehicle’s moaning noise and intermittent stalling problem could be any number of things. It could be a failed alternator diode making the moaning noise and affecting the idle.
A failed alternator diode(s) allows voltage to flow both directions or no flow at all resulting in noise heard and erratic electrical operation. It could be a faulty idle air control valve. The idle air control valve can make noise and would account for the erratic idle and sporadic dying. It could be an accessory component, such as an A/C compressor, serpentine belt tensioner, or idler pulley, power steering pump making noise and placing undo load on the engine at idle. If you would like to have this done, a certified professional from YourMechanic can come to your car’s location to diagnose the noise and stalling issue.

car making womp womp noise and pop
ANSWER : A common cause of a noise like that is tire belt (internal) separation, flat spot(s) on tire or other tire defects. If the tires end up being excluded during a diagnostic, the CV axles, wheel bearings, and unfortunately the transmission and clutch have to be considered. The noise on turning is suggestive of a possibly defective outer CV joint but very loose tie rods ends and ball joints can sometimes be implicated. Also, it is possible to have a bad strut bearing, in the strut mount. Keep in mind, a "combination" of faults might be in play here. Your best bet is to request a front end inspection/diagnostic during which the responding certified mechanic will get this resolved for you insofar as identifying the root cause(s) and estimating the repair for you.

car won’t start.
ANSWER : A possibility is a faulty ignition switch. If the switch opens after the car starts, the engine will shut off. But, that is just a possibility and a diagnostic would have to be performed to rule that in or out. Be sure you have a fully charged battery that passes a load test. Starters motors can display intermittent operation if they are faulty. With a fully charged battery, if the starter motor does not run that signifies an electrical problem in the starter circuit (includes the ignition switch) or a problem with the starter motor itself. If there is power to the starter motor and yet it doesn’t run, the starter is condemned and replaced. Alternatively, if there is no power to the starter, or there is a big voltage drop anywhere on the circuit to the starter, then the circuit has to be traced until the fault in the circuit is found. Notably, faults can include high resistances, due to corrosion, wire strand breaks, or loose terminals, which can only be diagnosed using a voltage drop test. Regardless of what the underlying cause of the no start condition is, if you desire that a certified mechanic resolve this promptly, please simply request a no start diagnostic and the responding mechanic will get it diagnosed and repaired for you. Please let us know if you have further concerns or questions as we are always here to help you.

My car makes a chirping noise while in motion, the noise is more frequent based on how fast I’m traveling.
ANSWER : You should have the brake sensors checked to see if the brakes are worn to the sensor or the backing vent plate is rubbing the rotor. If both are good then you may have a front wheel bearing then is going bad and needs replaced. Only a physical inspection can verify the brakes are good and not cause of noise and the bearing is bad.

when i turn it make little noise. when press on brake and put on reverse it’s makes weird noise and shakes. thank you
ANSWER : It sounds like you may be dealing with a few issues. I would start by asking if there is a check engine light on? If there is, then getting the engine control module scanned for faults would be the first step to diagnosing the low power issue. As far as the noise over bumps and when turning, there could be a damaged CV joint or axle shaft, or there could be a loose suspension or steering component. Weak motor mounts could cause a weird noise and shake when going into reverse with your foot on the brake, so it’s possible those have failed as well. I would suggest having a qualified mechanic, such as one from YourMechanic, diagnose the noise over bumps and the noise when put in reverse.

Car makes thudding noise and shudders at low speed
ANSWER : Your car seems to have what is called a "limited slip" rear end which controls the amount of power coming from the drive train to ensure that the power is evenly distributed to both wheels. The limited slip clutch packs will chatter a bit when it is low on fluid or the fluid needs to be changed. I would recommend having an expert from YourMechanic come to you to have this shaking issue diagnosed and repaired properly.
