Top 10 2006 Hyundai Sonata Questions & Answers

there is a tsb for the brake switch in 06 sonatas. it must be adjusted or replaced by dealership. is your check engine light on, if so its probably code p0504

I had the same problem at 35,000 miles. I would be driving and suddenly the ESC Off Light would illuminate. It would disappear if the car was turned off, only to reappear after a few miles of driving. It turned out to be a faulty "brake light switch."

I had this problem with my sonata. The other day I had to start and restart my engine 43 times before the ESC OFF light went out and I was able to accelerate. I took it to the dealer and they replaced a brake light switch and said it was fine. The next morning it was doing the same thing. This time they said it was the throttle body so they replaced it and today it worked fine. We'll see tomorrow.

Ok this just happened on my 2008 Hyundia Accent. Here is the issue. DO NOT REPLACE YOUR IGNITION LOCK CYLINDER OR ANY PART. All it is is over time the oil in the locking mechanism dries and is used by dirt introduced by the key. The tumbler is no longer pins but strips of metal sitting against one another. When you insert the key the strip goes up and gets stuck and does not come back down. Thus not allowing the steering wheel to lock or the ignition to turn.

How to fix. Its easy and cheap a small hammer and a can of WD-40. I stress this next part DO NOT BASH THE ... OUT OF THE KEY THEN YOU WILL BREAK YOUR TUMBLER AND NEED TO REPLACE. Spray some WD-40 into the lock. Insert the key tap it gently with a hammer and try the key eventually the vibration will drop the piece and the car will turnover. Do repeatedly until you can start the car without a hammer. Than put WD-40 in your ignition tumbler every time you change your oil should never have this problem again. I was in the Navy where I was in charge of 20 plus High Security locks exposed to weather and dirt. A regular maintenance procedure we performed was to disassemble the locks and clean and oil them or they would gum up and lock and then we would have to spend hours breaking off a high security lock(not the easiest thing as you can imagine). I learned quickly it was easier to do preventive maintenance then to fix and replace. If your ignition is gummed up and won\'t turn it may take a hour or so to get it working properly again but it will work and it won\'t cost you 250+ in cash. Hope this helps.

more than likely you have a bad oil control valve if in fact you have an 06 sonata. They are chain driven engines... You can ohm out the valve and get a good reading even when the valve is bad. Pull it out and check to see if it is clogged, if it is thats more likely your problem. If it is clean, go ahead and replace the valve. Hyundai calls them the oil control valve (OCV) and usually located on the head close the the variable valve sprocket.

The Key less entry system in your Hyundai Sonata is part of the factory alarm system. If you have to replace a lost or damaged remote, reprogramming will be necessary. The remote is important because not only does it lock and unlock the doors, it also arms and disarms that factory alarm when you open or close your car doors.

There are 2 possible engines for your car. The diagram for each is listed below. Best of luck!

ya i recently had my battery go bad on me. 06 sonata is @ 58k. previous to the battery issue had noted as irritating and strange as it is that my hood latch was not releasing, so after a tow to the shop and a 3 day rental...parts and labor was over$500. the very nxt week even tho i asked them to take a look as id had the ESC off light illuminiate vry sporadically recently. was "noted and light is off now" by the shop. 3 days out of shop light on again....back in shop a week after first. now i'm being told the entire ESC electronics system needs to be replaced at just under $600. i am starting to suspect i shud have gone w a honda.

Check the water levels. I had my 2011 sonata for two years and it started doing the same thing. You can look on line to see how to check and fill water levels. It's a really simple fix and cost the price of distilled water if you dont have any on hand.
