Car makes popping noise
My car sometimes makes a popping noise when I accelerate. My cruise control stopped working, but the light comes on when I set it. It just wont hold a set speed.
Experienced mechanics share their insights in answering this question :
Hello. The vehicles cruise control system uses an actuator and cable to open the throttle body and hold cruise. The throttle cable and cruise control cable operate independently, but are both linked to the throttle body. Have an experienced technician inspect the cruise control issue, actuator and electrical system for faults.

Causes of Car Popping Sounds
Spark plugs that are worn or corroded. Defective spark plug wires. Clogged fuel filter. Internal ignition wiring or related ignition issue.
The outer joints pivot, allowing the front wheels to turn. When outer CV joints become worn, they can make a clicking, popping, or snapping sound, especially when the vehicle is cornering and accelerating. Another reason a car can make a popping noise when turning is because of a damaged tie rod.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
If you hear a pop noise when turning, it`s usually due to a worn component connected to your suspension system. The bearings in worn CV joints can pop in and out of place as the axle bends with the wheel. Worn strut mounts are hard to rotate, binding and then releasing in turns.
Unplug and Replug the Crackling Device: Unplugging and replugging your device can eliminate the possibility of temporary failure caused by one-time interference. If your device starts working again after replugging, you should check your audio jack for corrosion, blockage, and wear.
Pop & Bang, burble or crackle tunes achieve these sounds through delaying the retarding of fuel injection after TDC (Top Dead Centre) into the engine. This essentially means that excess fuel is injected into the combustion chamber for a short period of time after letting off the throttle.
One of the most common causes of a sputtering engine is an issue with the vehicle`s fuel system—the filter, pump, and injectors. These three critical components work together to ensure fuel flows smoothly from the fuel tank to your engine`s fuel injectors, and then pumps into the engine evenly.
Hose Noises (Boiling and Bubbling)
This mean there is a hose failure, or that a bad gasket has compromised the cooling system. When a hose fails, it makes a soft hissing noise like a balloon with a small hole. If you hear that noise, check under your car for spilt fluids and get your hoses checked.
If your car is making clicking sounds when driving, a likely culprit is low or dirty engine oil. Motor oil lubricates all of the components so that you can drive with ease. If you are running low on engine oil, the metal parts may start to tap and grind over time.
“It`s a normal, common occurrence,” he says. But if the constant cracking is coupled with consistent pain or swelling, that can be a sign that something is wrong. That`s the time to see a doctor, Dr. Stearns says.
Step 1 – A strut or shock is designed to dampen unwanted vehicle motion, if these components wear they will become loose or leak which can create popping, banging, and rattling noises.
Crepitus is the abnormal popping or crackling sound in either a joint, like a knuckle, or in the lungs. It may be faint or loud enough for people to hear. It often comes with a popping or crunching sensation, which can sometimes be uncomfortable or painful.
Pops and clicks are unwanted audio artifacts caused by the powering up and down of components within the audio subsystem. This is noticeable on PCs when an audio module is either loaded or unloaded (at module load time the sound card is powered up and causes a popping noise on the speakers).
as they cool off, they contract at different rates depending on what they are made of and how fast they cool. Stresses build up in the joints between them until the static friction breaks into sliding friction; each time that break occurs you hear a tink.
Dirty or bad spark plugs won`t cleanly ignite the fuel causing the vehicle to misfire or sputter. You`ll either need to replace or have them cleaned. Because engine sputtering is a symptom of something more serious, it`s important to rely on an experienced mechanic to diagnose and repair the problem.
Spark Plugs
They ignite the air and gas mixture in the combustion chamber to fire up the engine and keep it running. Dirty, old, worn, or misplaced spark plugs can cause your engine to misfire – sputter – and even stall if the plugs are really bad.
Damaged CV joint: The most common cause of a clicking or popping sound from the wheels is a broken CV joint. The CV joints, which stand for Constant Velocity, are essentially the wrists of your vehicle`s steering system.
This means that coolant is leaking down through a cylinder into the crankcase. This usually indicates a blown head gasket or cracked cylinder head.
There are many signs of a failing ball joint or control arm bushings including: Clicking, popping, or snapping sound when the wheel is turned. Eventually, the clicking and popping can turn into a squeaking sound at the end of a stop, when the gas pedal is used, and/or when turning the steering wheel.
popping or knocking noise: a popping or knocking noise from the area when you go over bumps is the most common sign of a faulty sway bar link. these sounds will typically come from the area near the front tires. reduced handling: a broken sway bar link means the sway bar is no longer attached to the vehicle.
noise while driving: a knocking or thumping noise — especially over bumps — can indicate worn struts. bad front strut bearings may also cause a popping noise or a binding feeling when the steering wheel is turned.
Worn-out Ball Joint or Tie Rods
Each tie rod and ball joint has a ball-type socket with a stud that fits into the corresponding part of the steering system. It`s possible for the joints to create a clunking or popping noise when they wear out.

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.

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.

Something under my car. Is making a terribly loud popping noise ( multiple multiple pops) 2003 Mercedes ML350
ANSWER : Hello – noises from under the car when starting and stopping are most likely from suspension components, especially with your advanced mileage. The vehicle rocks front-to-back in both scenarios because of shifts in weight distribution. Worn ball joints, control arm bushings, sway bar links, and strut bearings are all stressed during start/stop activity. I would recommend a thorough inspection of the suspension for work or failing components by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

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.

Car makes noise only in the morning
ANSWER : 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.

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.
