Default EPS electronic power steering and squealing

Is anyone else having problems with Elanta 2009's electronic power steering system? I was driving my car and the power steering went unexpectedly almost causing an accident. I shut the car off and when it was re-started, it was working again and EPS light was off. I am taking it to the dealership soon to see what they will do. It has also been making a loud squealing sound for a few months now. It started out occasionaly making noise when I would back up or turn the wheel to the side but is now squealing pretty consistently. I had it looked into when I got an oil change and no one can figure out what it is from. All of my belts were checked and are tight. I believe it's linked to the power steering.

I personally think the steering on my 09 is kind of lifeless and devoid of feedback, but I think that's just the nature of EPS.

The power steering on your (our) Elantra(s) is different than what cars traditionally use. Instead of a belt-driven hydraulic pump providing fluid under pressure to the steering rack, you have an electric motor mounted directly to the steering column. Not sure about what kind of noise, if any, this electric power steering motor makes when it fails, but I'd guess that it would be different than what we're used to, or it probably actually make no noise at all, you'd just get an EPS light and heavier steering effort. Maybe someone who is experience with the symptoms of EPS failure can chime in here.

Let us know what the techs find. I'm pretty sure that EPS unit is expensive if you have to buy one from Hyundai out of warranty. FYI,just in case you do end up needing an electric steering motor, check out salvage yards near you for a motor from a low mileage car. You should be able to locate one near you using Car-Part.com--Used Auto Parts Market . I'll bet you can obtain one, if needed, in like new condition for a LOT less than a new unit from the dealership.

it is not the power steering. It is slipping belt on alternator...
I am 99% sure this is the problem here.

If BCM/ECU detects no charging, EPS is shut off. EPS requires huge amount of current so it will not work when alternator is not charging.
The squeaking/squealing noise is caused by the slipping accessory belt. Check it.

I would not agree with you.
Comparing EPS in Elantra to hydraulic PS in Rondo I find EPS to provide better feedback. At low speeds/parked car the steering wheel is very light, but when I start driving it becomes more stiff. It is not the case in Rondo. I discovered that it is very loose when driving...

I can't speak to the Rondo. I've owned/driven a lot of cars, though, and the Elantra in my opinion has relatively numb on center feel, as well as mediocre linearity of boost off center and sub-par road feedback. Certainly not one of the better systems on the market. If you get a chance, drive a Mazda3, a BMW 3-series, a Honda Fit, or a Mini Cooper from the late 2000's. Those are some cars that come to mind off the top of my head that have superior steering, and better by far than my Elantra. Is the E's steering horrible? No. But not great by any stretch of the imagination after you've experienced some of the really well-engineered systems out there.

09 HD Elantra does not have ppower steering...

It is MDPS.. Motor Driven Power Steering.. electric motor on column that provides assist

No power steering belt to drive P/S pump, as there is no pump/oil/hoses under hood

Scan MDPS for codes, there is a module update applicable to a range of ROM

so does it have it or not??



It is whatever you call it, my manual says EPS. Anyway, the bottom line is that the fuse on EPS is 80A, meaning it needs lots of power. Hence, very likely to hear belt slipping on alternator if it is loose enough.

The car is equipped with a plain old manual rack like an old 70's Pinto..

The car does not have power steering in the sense of having a P/S oil pump using oil under pressure to work slave cylinder inside power assist rack, open hood, you will only see 2 drive belt, one for alternator-water pump, other for A/C...

Elantra has module and large motor on steering column there under dash, the motor provides assist to the steering column based on direction/torque sensor values from driver tuning steering wheel for module to cypher and rotate motor to provide assist.

Just saw this post. My wife had an issue with her HD where "EPS OFF" would randomly appear, including in mid-turn. She took her Elantra to the local mechanic for the 90,000KM service where he replaced the timing belt and everything else specified but the EPS issue kept coming up. He told her to take it to the Hyundai dealer (wise man!). Hyundai booked it in, and ended up finding a fault with the ECU! Replaced the entire ECU at a cost of over A$2000 under warranty! No problems since.
