Just curious to know the logic behind why a car might reduce power.

Maybe you should try and drive a car without power assistance and you will see the logic immediately. Turning the front wheels with the car standing still is when it requires the most force. Just letting you car roll a little bit will immediately require a little less force. Even so, at low speeds, e.g. parking that's when steering becomes/is the heaviest. Thus requiring relative more power assistance.

At those sort of low speeds there is very little or even no requirement for the driver to really "feel" the steering, you just want to able to turn the steering wheel quickly and effortless

If you're driving at 100 km/h, a properly set up car (allignement) will require only minute steering inputs, with little effort. That's just how the mechanics (should) work. Going round bends at those sort of speeds require small steering inputs. Also, at these speeds, steering feel becomes very relevant and hence the assistance is somewhat dialled down.

Cars that have power steering that don't adjust based on speed, tend to be a little more heavy in feel at slow speed and a little to light at high speed. Speed adjusted power steering adjust that exactly the other way, as it is more convenient and safer.

Yes,the steering feedback increase with speed in some vehicles,but that does not mean that it cuts off.

As much as this is an issue, Loss of powersteering especially in EPS unit (Like the one found on Swift, Ertiga, i10, i20, Polo, Vento, Verna and various others) is not dangerous. Agreed steering effort will increase considerably, especially at slow (or no) speeds, but at highway speeds you will hardly notice it (A proper EPS unit should turn off completely between 40 and 80 kmph, from what I know). Also, note that even in power steering, the wheel is linked directly to the wheels.

As pointed out by several other members, yes on some cars the power steering cuts out completely above certain speeds.

Same thing happens in my i20 sometimes while parking especially when parking in tight spots where multiple steering wheel movements are required. The steering wheel becomes very hard as if there is no power assist.
Tried talking to hyundai after sales but to no avail!

It should be fine now. He checked on the diagnostic tool for Pending and Current DTC's couple of times after erasing the History DTC, nothing showed up. Seems to be fine.

Thanks to you all for the suggestions.

Observed the same issue on my 2013, Ertiga ZDI. Happened in March, 2017.
MASS diagnosed it as torque sensor problem having a loose connection. The engineer fitted it. But there was no way of wishfully recreating the problem and verifying if it's solved. So assumed the problem to be solved.
The engineer says that the coupling gets loose if the cars lands in some ugly pothole at high speeds ( Which as far as I can say never happened to my car ).

The problem appeared again now in April, 2017. Planning to visit MASS again. From what I can surely recollect, the car did not land in any pothole at high speeds.

Dear Panchi, What about you? Have you seen this problem again?

Facing the same issue with my uncle's ertiga zxi 2016. EPS warning light turns on right after cranking(from standstill) and power assist is zero. Restarting the car somehow fixes the issue. Occurs only once in a while.
A quick scan using obd2 scanner reveals the dtc to be C1112- torque sub mismatch(history).
More info on this dtc- this dtc is lodged whenever there is a mismatch in values reported by the main torque sensor and secondary (sub) torque sensor to the EPS module.

It could be anything from a weak battery/loose couplers of torque sensors to faulty EPS module.

I am planning to vist MASS tomorrow to get it fixed while the car is still under warranty.
Since this is a known issue, I hope they have some sort of Technical service bulletin (TSB) on this issue.

Will keep you guys updated.

Hi Guys

Any solution to the problem that you described? I have already got my steering assembly changed on my ciaz and the steering still feels to be harder.

Can anyone of you please help . Can you please tell me if your problem is resolved and how

Hi RaSing,

My problem at least surely seems to be a torque sensor issue. The service engineer cleaned the pins and refitted the sensor and the problem never appeared again. Drove almost 10k kms now without a glitch

Do you remember, what were the symptoms and how did they figure out that it was indeed the torque sensor ?

If i recollect correctly, I saw randomly the power steering error light coming on. The service advisor connected his diagnostics tool and figured out that the error code corresponds to the torque sensor. He then said the coupling could have gotten loose when you ignore a pot hole or speed bump and land with a thud. He then cleaned and refitted it snugly again and the error never popped up.

It's also possible a weak battery can show this up, but I am not sure.

Thanks rajwheels. Looks like my problem is a little different then.

Hi All
I am also facing this problem in our 2014 Ertiga Zxi. I have been facing hard steering since last week and today morning the steering light came on and steering was super hard. Logged into team bhp and found this thread at first. I went through the thread and understood this is a common issue. I will be visiting our regular MASS and hope ours is also loose connection issue. I will update once the issue is resolved.
