my car has theissue that it often lose power steering suddenly while turning.nothing leaks but there’s clunky noice when turning

My car often lose power steering when turning. There's no leakage, no grinding noice,the car is fairly new, no wears physically. However, there's clunky noice when turning the steering wheel sometimes. It could be possible related to the event that the car hit a curb at 25 mph on a snowy day. But the car is checked by multiple mechanics saying that no damage or bent whatsoever physically in suspension and steering rack. But dealer said the noice came from the steering rack.

My car has 14000 miles.
My car has a manual transmission.

Experienced mechanics share their insights in answering this question :
The only way to determine if the collision caused damage is to carefully MEASURE the alignment and, as well, the frame dimensions using a tram. If those steps have not been specifically taken, what the mechanics have told you about "no damage" is meaningless. If the dealer has told you there is a problem with the steering rack, there very well could be and that possibility should be investigated. If the rack is faulty, it should be repaired or replaced. There is not supposed to be any clunking noises when you turn the steering wheel. The fact that there is a noise indicates a problem. The noise could be due to a problem with the strut bearing that allows the strut to turn freely with the steering knuckle, a defective tie rod end, a sway bar link or component and so forth. If you have hydraulically (not electric) assisted powered steering, loss of power assist could be due to a fault with the pump, the pump drive belt, or rack. Based on what you are describing, I would recommend you request a steering inspection – intermittent loss of assist and the responding certified mechanic will pinpoint the origin of the noise, as well as the cause of loss of assist, and get the required repairs implemented. With regard to the possibility of damage to the suspension and/or frame due to the collision, the ONLY way to determine that is to have those components measured using the appropriate tools and having in hand the Factory Service Manual which contains every relevant frame measurement for reference. You CANNOT visually look at a vehicle and determine if it is straight and undamaged because some of the specifications are measured within tens of thousandths of an inch (toe, for example) or tiny fractions of a degree (wheel camber). A carefully selected shop with trained individuals will have to perform such an inspection.

How to Identify and Fix Common car Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced mechanics :

Tie Rods: A clunking noise when turning typically means there`s a loose or broken tie rod. Sway Bar Link: With a failing sway bar link, you will not only notice a knocking noise while you are turning but also poor handling.
Newly added to the 2016 WRX EyeSight® system is Lane Keep Assist, which uses the vehicle`s electric power steering system to help the driver keep the vehicle within its lane when driving on the highway.
You`ll know when the axle is about to fail when you begin to hear a loud, rhythmic clicking noise coming from the front wheel as you turn. That noise is due to a lack of lubricant in one of the CV joints. A CV axle is a critical component of your Subaru, so it should be replaced properly by an authorized Subaru expert.
Clunking

If the clunk happens when you drive over bumps, there might be a problem with your car`s suspension, or part of the exhaust could be loose. However, if your car clunks when you`re turning corners, it could be a problem with the steering, wheels and tyres, or a worn-out wheel bearing.

A clunking or knocking sound is another sign of a steering rack problem. The clunking noise will sound like someone knocking on your door but from below your car – “kok!”.
A sure sign of air in the system is what sounds like a mildly disgruntled cat under the hood. This growling will get louder during power steering-intensive movements such as parallel parking. The first thing to check when the power steering starts moaning and groaning is the fluid level.
Quick answer: Avoid Subaru WRX Year Models 2015 and 2016

As with most cars when they first debut, it`s not a major surprise that the earlier 2015 and 2016 models have the most problems. They both suffer from a lousy clutch after being used for a while. We recommend avoiding them due to this issue.

But, in general, you can expect a Subaru to run for over 200,000 miles. That`s good news for fans of the Subaru WRX, boasting a stunning new exterior design and a better turbocharged engine.
The 2016 Subaru WRX can reach a top speed of 153 mph with this engine configuration. Another engine available here is a 2-liter Intercooled Turbo Premium Unleaded H-4 that makes 268 hp @ 5600 rpm and 258 lb. -ft. @ 2000 rpm.
The header piping from cylinders one and three are different in length from those from two and four. This means, the exhaust gas coming off the engine has to move through different lengths, as does the sound it produces, which creates an uneven tone (much like a rumble), instead of a smooth tone.
If you hear a clunking sound when you turn your steering wheel slightly then the metal U-joints might be rubbing against the steering shaft. You can try applying lubricant to the joints to see if that solves the problem.
Knocking and shaking coming from your engine can be the telltale sign of bad fuel injectors. Another symptom could be misfiring or a vibration. Each engine whether it be a Diesel or gas powered, has cylinders. The more cylinders an engine possesses, the more power the vehicle has.
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.
Common signs include a very tight steering wheel, leaking power steering fluid, grinding noises when steering, and a burning oil smell.
While turning a corner, if your steering feels slow to respond to the steering wheel inputs you are making, chances are your power steering pump is failing, especially if accompanied by a whining noise. The steering wheel may also feel stiff when turning — another indication of a power steering pump failure.
The power steering unit comes as a whole – there are no removable or serviceable components so if one part fails, the whole unit will need to be replaced.
You can still bleed your power steering using the traditional method if you have a bleed valve. This is just an option you have if your vehicle comes with a bleed valve. It`s easier to do it this way since you don`t need to elevate the vehicle and it takes less than 5 minutes.
Sound — Usually the first indication of worn or loose ball joints will be a faint, intermittent clunking noise that seems to be coming from a corner of your vehicle. The sound may be more pronounced when going over a bump or a dip or when going around a corner.
The power steering and A/C have pressure switches that are known to cut out the power steering assist and the A/C compressor under heavy load conditions. Your transmission may not be shifting correctly due to the engine not running correctly.
Sound — Usually the first indication of worn or loose ball joints will be a faint, intermittent clunking noise that seems to be coming from a corner of your vehicle. The sound may be more pronounced when going over a bump or a dip or when going around a corner.
Damaged or Worn-out Control Arms

Worn-out control arms may cause the wheels to move out of alignment, which causes the vehicle to make a clunking noise as you steer the wheels on a bump. The damage may be extended to the body mount and cause the cab compartment to vibrate.

A clunking, rattling, or squeaking noise from your front end while driving can be annoying and unnerving. Oftentimes, this noisy symptom means there is a problem with your vehicle`s suspension system. These sounds typically occur when driving over uneven surfaces, bumps, or potholes.

Hard to turn vehicle when car is idling. No leaking of power steering fluid under the car
ANSWER : Hi there. Chances are the power steering pump is at fault for the steering wheel being hard to turn both directions at idle. It could be, a faulty power steering pressure switch not sending a signal to the computer to raise engine rpm (revolutions per minute) to compensate for power steering load at idle. The power steering fluid level being low, indicates there is a power steering fluid leak even though, your not seeing it on the ground. Replacing components without proper diagnoses, can be expensive and time consuming without resolution. I recommend having your vehicle’s steering wheel is hard to turn at idle be diagnosed and repaired by a certified technician, such as one from YourMechanic.

power steering fluid is leaking
ANSWER : With a power steering fluid leak that big, you certainly should have the vehicle inspected as soon as possible to find the exact cause. Any of the components you listed can be the source of the leak. The power steering pump as well as the rack & pinion steering unit rely on the fluid for lubrication as well as cooling. The whining you hear is from the pump when the fluid runs low or empty. Your issue can be caused by something as simple as a fluid hose right now, but continued ’running dry" of the power steering fluid, can result in damage to both the pump and the rack & pinion unit. If that happens, you can take what may be a repair of a few hundred dollars and turn it into a repair of a couple of thousand dollars.

had power steering pump replaced but power steering fluid is leaking
ANSWER : This suggests that you may have a leak somewhere else in your power steering system such as one of the hoses or the rack and pinion system. As you may know, the power steering system is a highly pressurized system that can have as much as 300+psi of pressure in the system at times, so it is not uncommon for these types of leaks to happen. If you’d like to get this fixed, I would recommend having an expert from YourMechanic come to your location to diagnose the leak in your power steering system and make the the necessary repairs to fix it.

steering wheel won’t unlock my key turns only to turn lights on but that’s it can’t unlock steering wheel to start the car what to
ANSWER : The steering lock may not be unlocking either due to a faulty ignition lock housing or more commonly as the cars age a faulty spring at the steering wheel on the under side of the column. If the ignition lock housing is the issue the housing can be replaced. It s a bit tricky as the mounting bolt has break off heads and generally need to be driven out with a punch. If the lock is not disengaging because of a faulty spring on the ignition lock many owners have had the spring removed by having it drilled out of the housing. However, removing the spring may permanently disable the steering lock. The last option would be to replace the steering column. You may want to enlist the help of a mechanic who can recommend the proper repair for your situation.

Power steering fluid groaning noise. Power steering leak?
ANSWER : Hello. A groaning noise is an indication of low power steering fluid. If you had your power steering fluid serviced about 5 months ago and it is making a groaning noise again most likely means your power steering pump has gone bad or your power steering leak has going from minor to moderate. I can tell you that Honda Accords are one of the most common vehicles for a power steering pump leak to occur on and require a pump replacement. If not a leaking pump it could be power steering hose leaking fluid. I suggest that you have a power steering fluid leak inspection done otherwise you will have to keep filling up your power steering reservoir until it is fixed.

Power steering loss, no belts are turning but the car is running fine. I also have a soft pedal. Whats wrong with my car?
ANSWER : I have only seen this situation once in my 30+ years and it turned out to be a broken crankshaft pulley. Belts are driven by the engine. The crankshaft pulley spins the belts, which in turn spin the air conditioner compressor, power steering and water pumps, and the alternator. The vehicle should be towed to your local repair shop and not driven. Without the water pump spinning to circulate the coolant, the engine will quickly overheat and result in more extensive damage.
