I had installed a less expensive battery a few months prior, which was slightly smaller than standard Hyundai size. Didn't notice at first that previous owner had removed the battery block. As a result, cable came loose around battery post, temporarily removing 12vdc battery electrical connection, which is essential to power my non-hydraulic, all-electric power steering on my Elantra. I bought the battery block kit for ten bucks, and installed a new battery block to secure battery so that it didn't jostle around anymore and loosen the battery cable(s) from the battery post(s). Then I pushed down the cable clamps on the battery posts as far as they would go, and tightened the cable clamps as tight as possible by hand tightening. (I used 13mm socket wrench with long extension for battery block bolt, and 10mm crescent wrench for cable clamp bolts.) This solved the problem.

P.S. The battery I changed had been the original one on my 2008 Elantra (which I bought used in Dec. 2016 with about 110K miles, and have since put about 60K miles on it in the past 3 years) and was worn out, but I'm surprised that it lasted 11 years. And I did save 12 bucks with the smaller, non-standard battery, but losing my power steering and suddenly feeling like I'm driving a truck instead of a car on Interstate 287 at 70mph was NO fun. But I was glad that I didn't have to spend 400 or more to replace a (hydraulic fluid) leaking power steering unit, because this car has NO hydraulic fluid in the power steering, because it is all electric! (Just make sure that your battery connection is secure, however... ha ha ha...)

Beware of the 2007-2009 Hyundai Elantra they are cheap for a reason and I will never trust another Hyundai again. If I won one in a contest I would get rid of it immediately. The transmission seems like it's going to fail at any moment, the electric power steering is a constant problem, the interior makes rattling noises, the headlights allow moisture causing the bulbs to fail regularly, it's an all around piece of crap.

If I had more money and time before I bought this car, I would have defiantly bought something else but I am a college student that has a lengthy commute, on a tight budge and my '96 Neon was eating me alive each month. Do yourself a favor don't buy a 2207-2009 Hyundai Elantra I can't speak for Hyundai's other models but I will not but another Hyundai made car again.

Took back to same dealership, repair estimate $2500.00 which is total crap. This electronic power steering is a piece of crap. The dealership is now stating the motor in the electronic power steering is out. As far as I am concerned it should be considered a safety issue with this car! The manual says you can drive it like that but if I have to maneuver that car in a split second I WILL have an accident. This particular problem with this car should be considered a default. This car is 4 years old and no way with the mileage should something like this be out. I will never purchase another Hyundai product and spread the word about this issue.

This was a scary moment for me .. I was driving my car approx 45-50 mph when the steering wheel wouldnt move. I tried to turn but my car continued to go straight . I had all I can do to get the car to turn a little bit as it felt as though something had snapped. I was able to turn the car enough so that i did not go onto the side walk and hit a building. Once I put the car in park, the steering wheel would not move at all. This couldve been a very dangerous outcome. I had the car towed to the neareast Hyundai dealership. It was found that the problem was a faulty part in the steering column and it will need to be replaced. How do I possibly begin to feel safe driving myself let alone my 5 year old son around in this vehicle.
