Car Clicking on Left Turns: Power Steering and Low Oil Pressure Symptoms Explained

Hearing a clicking sound when you turn left and then noticing your oil pressure light flicker can be unsettling. You're driving along, make a left turn, and suddenly there's an audible click coming from somewhere under the hood or near the wheels. At the same time, your oil pressure gauge dips or the warning light blinks. These two symptoms happening together aren't random. They often point to a mechanical issue that, if ignored, could leave you stranded or lead to expensive repairs. Understanding the connection between that left-turn click and low oil pressure is the first step toward fixing the problem before it gets worse.

What causes a clicking noise when turning left?

A clicking sound during left turns usually comes from one of a few common sources. The most frequent culprit is a worn CV (constant velocity) joint on the front axle. When CV joints wear out, they click or pop during turns especially sharp ones because the joint can no longer smoothly transfer power to the wheels at an angle. Left turns put extra stress on the right-side CV joint, which is why the noise might only happen in one direction.

Other common causes include:

Worn wheel bearings – A failing bearing can click or grind when the vehicle shifts weight during a turn.
Loose or damaged suspension components – Strut mounts, sway bar links, or ball joints can produce clicking or popping sounds.
Power steering system issues – Low power steering fluid, a failing pump, or air in the system can cause clicking or whining that's more noticeable during turns.

What does low oil pressure have to do with clicking during turns?

This is where it gets interesting. Some vehicles use an oil pressure switch that can click or make noise when oil pressure fluctuates. When you turn left, a few things happen mechanically that can cause a temporary drop in oil pressure:

Oil sloshes to one side of the pan – During a sustained left turn, engine oil moves away from the oil pickup tube. If your oil level is already low, this momentary starvation can cause the oil pressure sender to register a drop and sometimes click audibly.
Engine load increases – Turning often involves slight acceleration or deceleration, which changes oil demand.
The power steering pump draws engine power – If the power steering system is struggling (low fluid, failing pump), the added load can affect oil pressure readings, especially at idle or low speeds.

So if your car clicks on left turns and you're seeing low oil pressure symptoms, there's a real possibility these two issues share a root cause or at least influence each other. You can learn more about why the oil pressure switch clicks when turning left and what causes it.

What are the warning signs of low oil pressure?

Low oil pressure doesn't always announce itself loudly. Here are the symptoms to watch for:

Oil pressure warning light on the dashboard – This is the most obvious sign. If it flickers during turns or at idle, take it seriously.
Engine ticking or clicking – When oil pressure drops, the valve train and lifters don't get enough lubrication. They tick or click, especially on startup or during maneuvers that shift oil around.
Low oil level on the dipstick – Always check this first. A simple low-oil condition causes most oil pressure problems.
Engine running hotter than usual – Oil helps cool internal engine parts. Low pressure means less cooling.
Decreased engine performance – In severe cases, the engine may feel sluggish or rough.

Could the clicking be from the oil pressure switch itself?

Yes, absolutely. The oil pressure switch (also called the oil pressure sender) is a sensor threaded into the engine block. It monitors oil pressure and sends data to your dashboard gauge or warning light. When these switches fail, they can produce a faint clicking sound sometimes confused with engine knock or valve noise.

If the switch is failing, you might notice:

Intermittent oil pressure warnings that come and go
Clicking that seems to come from the engine block area rather than the wheels
Oil pressure readings that jump around erratically
Warnings that appear specifically during turns or acceleration

Replacing a faulty oil pressure switch is usually straightforward and relatively affordable. If you suspect this is your issue, this breakdown of replacement costs for steering-related noise issues can help you understand what to expect at the shop.

How do I figure out which problem I actually have?

Because clicking on left turns and low oil pressure symptoms can come from different systems or the same one you need to narrow it down. Here's a practical diagnostic approach:

Check your oil level first. This takes 30 seconds and rules out the simplest cause. If it's low, top it off and see if the symptoms disappear.
Listen to where the click comes from. A CV joint click comes from the wheel area. An oil pressure switch click comes from the engine. Power steering noise comes from the front of the engine near the serpentine belt.
Notice when it happens. Does it only click during turns, or also on straight roads? Does the oil light flicker at idle too? The more specific your observations, the easier the diagnosis.
Check power steering fluid. Low power steering fluid can cause clicking or groaning during turns and may indirectly affect engine load and oil pressure.
Get a mechanical inspection. If you're not sure, a mechanic can put the car on a lift and check CV joints, wheel bearings, and suspension components visually. They can also test oil pressure with a mechanical gauge to see if the sender or the engine is the problem.

What mistakes do people make with these symptoms?

The biggest mistake is ignoring it. A clicking noise during turns that's paired with low oil pressure warnings is not something that fixes itself. Here are other common errors:

Assuming it's "just the CV joint" and ignoring the oil pressure light – You might have two separate problems happening at the same time.
Adding oil and forgetting about it – If oil is low, find out why it's low. Burning oil, leaking oil, and neglected oil changes all need different solutions.
Replacing parts without diagnosing first – Throwing a new CV axle at the problem won't help if the click is coming from the engine or power steering system.
Driving with the oil pressure light on – Even for a short drive. Oil starvation kills engines fast. If the light stays on, pull over and shut the engine off.

What should I do right now if my car is clicking and showing low oil pressure?

Take these steps in order:

Pull over safely if the oil pressure light is on solid. Do not keep driving. A solid warning light means dangerously low pressure.
Check the oil level. If it's below the minimum mark, add the correct oil for your engine before driving again just to get to a safe location or shop.
Note all symptoms. When does the click happen? Does the oil light flicker or stay on? Any other noises or dashboard warnings?
Avoid sharp left turns until diagnosed. If a CV joint is failing, it could break completely and leave you unable to drive.
Schedule a diagnosis with a trusted mechanic. Tell them exactly what you've observed. Ask them to check both the steering/suspension system and verify oil pressure with a mechanical gauge not just the dashboard reading.

Quick checklist before your shop visit

☐ Oil level checked and topped off if needed
☐ Power steering fluid level checked
☐ Location of clicking noise noted (wheel area vs. engine)
☐ Conditions that trigger the click documented (speed, turn radius, temperature)
☐ Dashboard warning lights and behavior recorded
☐ Any recent oil changes or repairs noted for the mechanic

Getting ahead of this problem now is far cheaper than dealing with a seized engine or a broken axle on the side of the road. A straightforward diagnosis usually takes less than an hour and gives you a clear path forward.
