Car has chirping sound on rough roads

My car has around 112k miles and is in excellent condition except for the following problem. Behind the driver’s seat in the rear-inside area, there is a chirping sound. This happens when I’m driving on a rough-surfaced road. I was told by the dealer that this is normal due to the stress in the rigid frame of the car. I don’t agree with him. The sound is coming from the area of the carpets that cover the left quarter windows. I decided to disassemble the area, but everything looked normal. I even added insulation, but the chirping still exists. My car has never been in any accident and I
Experienced mechanics share their insights in answering this question :
I would only recommend having a qualified mechanic drive and duplicate the problem and see if it is in the rear suspension or in the body mount under the rear seat area under the car. Depending on the noise, the mechanic will locate the noise and access the problem to lube or repair the part that is chirping. It sounds like a body mount to me and could be the drivers seat frame or body mount area.

Usually, chirping or squealing noises when accelerating indicate a slipped or loose belt. Less frequently, it could point to a misalignment in the drive pulley of the water pump or another accessory. if it has a manual transmission.
Vehicle Suspension

The squeaking suspension parts are often associated with a lack of lubrication when metal-on-metal wear is happening in connections such as the tie-rods, suspension joints and steering linkage.

A few common causes for squeals are low or contaminated transmission fluid, components faults, or internal transmission issues. Automatic transmission use fluid pressure and a series of electronic solenoids and sensors to operate the transmission.
(also chirrup, uk/ˈtʃɪr.əp/ us/ˈtʃɪr.əp/) (especially of a bird) to make a short high sound or sounds. [ + speech ] to say something with a high, happy voice: “Morning!” she chirped.
The first indication of any trouble with suspension will probably come from an unusual noise. There`ll be a knocking, creaking or clanking from under the car. In extreme cases, your car might not want to drive in a straight line without you constantly making adjustments with the steering wheel.
There are four sounds in particular that you should look out for: creaking, grunting, rattling, and knocking. See your auto collision center if you hear any of these noises, and keep reading for more on the four sounds of suspension problems.
This will cause road noise and will also indicate a suspension problem such as worn struts, worn ball joints, and loose or worn tie rods. It can also be caused by improper alignment both front and on some cars, rear alignment.
The most common reason brakes squeak is that the metal wear indicator on the brake pad touches the metal rotor. This is normal and expected from wear over time, but does indicate you should replace your brakes soon. Brake pads have a built-in mechanism to inform the driver when they are getting low and need replacing.

I notice that if DSC is ON and I go from a bumpy rough road to a Smooth Straight Road. I hear a "kum" "kum" sound from the rear.
ANSWER : DSC is your car’s "Dynamic Stability Control" which is a form of traction control. Your car is equipped with sensors that monitor changes in the ride of the car which detect uneven surfaces or bumps in the road. These signals are relayed to the DSC system which then attempts to regain control of the car. The sound you are hearing is this system working properly as it should. This should be nothing to be concerned about.

My car has a high pitch chirping sound when accelerating. 2010 Subaru Impreza
ANSWER : Hi – your Impreza has a turbocharged engine for enhanced performance. This produces pressurized air for the engine, increasing power. To avoid over-pressurizing the engine, there are boost pressure controls, and a "waste gate" port to vent over-pressure – all electronically controlled. This can produce "chirping-like" noises under acceleration, especially during and after gear changes for manual transmission cars. This is normal behavior, and shouldn’t cause concern. If it seems excessively loud, I would recommend an engine inspection 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 has chirping sound on rough roads
ANSWER : Hello there,

A few different things can cause this type of noise. The most common would be interior pieces rubbing against each other, a wind noise, or one of the window seals.

I’d suggest having the car looked at by a qualified technician, such as one from YourMechanic, who will be able to diagnose this noise and determine if a fault is present.

Car sounds like golf cart when revving and braking; also leaking fluid; sound fades as car warms up
ANSWER : Hello,
There are a number of things that could make an engine noisy when starting up. Depending on the specific type of sound you are referring to, this will determine how to properly diagnose. If there is a bit of a hissing sound, this may be a sign of a vacuum leak. If this is more of a shrieking sound, this may be a sign of a worn out or out of adjustment serpentine belt. If there is a bit of a howling or growling sound, this may be a sign of a worn out or low on fluid power steering pump. A rattling or pinging sound may be caused by an ignition problem. An engine can ping (or knock) due to an improper combustion process. A "spark knock" is the result of combustion occurring too early. Early combustion can occur from carbon buildup inside the combustion chamber, a lean air/fuel mixture, and advanced ignition timing (spark plug firing too soon). A clattering type sound may be a result of improper lubrication in the valve train which could be a more serious problem and should be addressed as soon as possible. I would suggest having an expert from YourMechanic come to your location to diagnose and inspect your vehicle to ensure everything is in proper working order.

My car has a rough idle when I start my car, when I stop at a light my car turns off. Is it the purge sensor?
ANSWER : This may be a result of a dirty or failing idle air control valve. The idle air control valve reads the air intake as it is mixed with fuel prior to being injected into the engine at low speeds and at idle. Since this valve is controlled by the vehicle’s computer, it will adjust idle speed based upon other measurements such as engine temperature, intake air temperature and electrical system load or voltage. When you accelerate, the engine RPM increases, and as you let off the gas, the RPM slowly returns to the normal idling speed with the help of the idle air control valve making the transition from a higher RPM back down to idle speed. When the engine RPM drops below the normal range of about ~800 RPM, this often times will cause the engine to stall indicating a dirty or faulty idle air control valve. I would recommend having an expert from YourMechanic come to your location to diagnose and repair your idle air control valve.

I put the wrong key in my car and a few weeks later my car just shut down and it will not start I believe it’s the computer but…
ANSWER : Hi there. What had happened is the wrong key set the security to the vehicle. This is to prevent the vehicle from starting with the wrong keys. Try removing the battery cables (+) and (-) for 13 minutes. During that time, put the original key in the ignition and turn it on. Activate everything in the car even though there is no power. Then remove the key and hook up the battery cables. The computer should have reset and reset the security. If the security is still being tripped, then I recommend seeking out a professional, such as one from Your Mechanic, to help you
