May 2019: Battery light came on and off for a few minutes. Car sputtered and engine quit. Replaced alternator and battery; problem went away. Feb 2022: Battery light came on and off for a few minutes. Car sputtered and engine quit. Replaced alternator and battery. This time the mechanic noticed that oil was leaking from the front valve cover gasket and was getting into the alternator; thus the most likely source of damage to alternator.

I heard really loud sound in the engine but there's no check engine light. After of few days of driving and the day I decided to bring it to the mechanic, few miles away from the shop the the loud noise in the engine is gone then check engine show up and the oil pan appears. The mechanic said it was the oil pump and they said there's a metal shaving inside the engine, when they drain the engine oil.

The brakes on my 2006 Hyundai Sonata failed on me as I was driving. My car seemed to have not been working properly.

The contact owned a 2006 Hyundai Sonata. While driving highway speeds, the vehicle made an abnormal noise and smoke emitted from the engine compartment. The failure occurred without warning.

The check engine light starting going on and off. Our 19-year-old daughter was driving on the freeway at night when the light came on and it started making a loud noise. She stopped on the side of the freeway, turned it off and never could restart it. The engine died. It blew a rod. The car had regular maintenance. We hadn't had any work done recently that could have led to engine problems. The mechanic said it had oil and he couldn't explain what happened.

Mechanic says engine has to be replaced.. it's noise from inside the engine and dangerous to drive with it.

It is having the same problems that the engines are being recalled for now. It is making tapping and pinging sounds. I have looked the vehicle and have seen people have been complaining about their 2006 Hyundai Sonatas doing the same thing. Scrap yards have these cars there with blown engines. My son is having to pay on a loan on a car that he can not even drive. We have called the banks and insurance. It will cost more to fix the engine than what he owes. Why are 2006's not being recalled also?

My wife and I purchased the vehicle on 10/11/2016 at J.D. byrider of mansfield and noticed that there was a clicking type sound when starting vehicle. On 10/14/2016 while my wife was leaving work she went to turn the vehicle and it was very hard but managed to get home and woke me up, I then went out and viewed that the serpentine belt was very loose and that there was a pulley laying by the engine; jd byrider fixed the issue of pulley and belt; after we received the vehicle back we noticed that the clicking type noise was still there.

Purchased this Sonata used 3 months ago with 45,800 miles on it, drove it 4,000 miles and it developed a engine ticking noise which now has turned into a knocking sound at 1800 rpms goes away, then comes back at 2200 rpms. I contacted Hyundai customer service to establish a case number. The dealer has removed the oil pan and found shavings saying it needs a "short block" motor replacement at a cost of $5,800. Hyundai motor America denied the request for repair totally. I find that at 50,000 miles and being only the second owner, this motor had a defect that should be acknowledged as a defect and they should stand behind there product! this is my third Hyundai, new 2005 and new 2007 and I'm seriously in the market for a new SUV but if Hyundai won't stand behind a costly defect like this they will loose a 10 year very loyal customer forever.

While driving, the damper pulley seperates and the power steering fails along with the water pump and the alternator. This damper as it is called is a device that drives all the belt powered devices on the engine. I asked the dealer if there was a recall on this and the reply was no. How can a power steering failure not be a recall? when you are turning and the power steering fails I would say the majority of drivers would not be able to steer the vehicle out of this situation. Look online and view all the places that list this problem. This is a big safety issue the vehicle steers very hard and is difficult to control.

Vehicle was in motion on Chicago city streets and temp gauge started to rise slowly and I began smelling anitfreeze. Later the temp gauge rose signigigantly the antifreeze began leaking heaily from beneath and smoke began rising from under the hood very heavily. Upon auto shop inspection the repairman noticed that the smoke was coming from an area by the engines' heating core rubber hoses. The repairman removed the heating core rubber hoses for inspection and found that the engines' heating core metal tubing nosles/nipples appeared as though they have been dipped in acid. The repairman concluded that heater core metal tubing nosle/nipples severe corrosion is not normal wear or tear or a common automobile problem.

My Sonata 3.3L V-6 engine with what appears to be a very common and dangerous problem. This vehicle seems to begin stalling and slamming into 3rd gear fail safe mode, luckily I have not been rear-ended due to this yet! I have read up extensively on this and found many with the same complaint on www.carcomplaints.com website. It appears many dealerships are aware as they have had vehicle in to be problem solved with what appears to be an electrical problem more so than a mechanical problem. After having my car into 4 different shops including a dealership the first time it happened with no fix and only a 'if we can't replicate the problem we can't fix it' response I get mad. We have ruled out everything possible; transmission, engine, relays, etc. For 4 months it has been in and out of shops trying to diagnose the problem. Which is happening so often now it is not safe and I am having to take out a loan to try and buy a new care. I cannot trade this in due to the problem. When it is running it runs great, until it slams into 3rd gear with no warming and you loose all acceleration or it dies completely. You can shut it off and restart it and it runs as if nothing happened, until it stalls again. The last mechanic having verified everything he was told to check has determined it must be in the computer. Some individuals said early on they had the computers replaces (at a big cost) only to have it happen again. My car is 10 years old and only has 118,000 miles on it. I hate having to get rid of this car but there is no way it is safe to drive in this condition. Hyundai seems to be ignoring this complaint as no recall has been issued and no help in repairing the problem. Too many cars at the aprx mileage with the same problem and leads me to believe a recall is in order or financial reimbursement for the months of repair to fix it should be made.

First, oil is leaking on alternator and area around, car needs a valve cover gasket, driver airbag light stays on, passenger sun visor wont stay up, the vehicle has 149000 miles on it. There are to many complaints for these subjects, a recall needs to be issued.

On lambda/lambda II mpi series engines, engine oil can leak onto the alternator, which could affect charging system function and potentially cause the engine to stall and not restart. This would result in a loss of motive power as well as affect power braking and power steering system function, which would unexpectedly increase steering and brake pedal effort, potentially increasing stopping distances and the risk of a crash causing injury and/or damage to property. Every make/model of vehicle that has this engine has oil leaks on the alternator and other critical components (I've replaced 3 alternators so far! ~$200 each! + labor!!!) yet only a certain year of the "vera cruz" received a recall because the cost to Hyundai would be higher to fix this issue on all affected vehicles (Azera, sante fe, and my Sonata etc. Models)

I own a 2006 Hyundai Sonata, at 100,000 (hwy miles) the front upper control arms became squeeky and detatched from the rubber bushings, making a horrible ride and clunking sound when I would put the car into gear. This problem makes the car bouncy and unstable. There is also a knocking or loud clicking sound in the engine at crusing speeds, when I barley push the gas pedal. It sounds like the air intake control valve. It goes away when I accelerate. The radio and cruise control electornics seem to work only when they want too!
