general problems of the 2006 Hyundai Sonata

I am filing this complaint regarding a serious engine issue with my 2006 Hyundai Sonata equipped with a 2. 4l gdi engine. My vehicle experienced [engine knocking, stalling, and then seized up indicating complete engine failure] without warning, posing a potential safety hazard while driving. The issue appears to be identical to the known manufacturing defects that Hyundai has acknowledged in its recall of 2013–2014 Sonata models with the same engine class type. Although my vehicle is not currently included in the official recall “ Sonata engine recall campaign it contains the theta ii mpi engine which constitutes and further solidifies proof of the ongoing manufacturing defects of theta model engine design and exhibits the same symptoms of sudden engine failure. This raises concerns that the defect may affect a broader range of model years than Hyundai has acknowledged. I urge NHTSA to investigate this issue and determine whether the scope of the current recall should be expanded to include earlier model years such as 2006. The defect creates a significant safety risk to drivers and passengers, and Hyundai should be held accountable for all affected vehicles—not just those produced within a narrow window.

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.

Driving on the highway and my car just died out of no where took it to get looked at only to find out the engine died car got so hot it had to sit over night to cool. Also was driving one day and rook a turn amd my brakes wouldn't stop took it in and found out the entire brake line was corroded had to spend thousands to get it fixed.

My vehicle was moving upon coming to a stop. I tried the brake system but my car wouldn't stop and caused an accident. That's what I remember.

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

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.

I was driving home and slowed to let someone in front of me turn left into a grocery parking lot. The car suddenly started surging mad I could not stop it with the brake pedal all the way to floor. However, I did hit the car in font of me, with no damage to her car. I had popped the front right side of the bumper on my car. So we went on with our business when she found no damage to her vehicle. I had to turn the car off to stop the car from moving. I called the dealer glenn Hyundai and told them of the incident, they in turn told me this would be nearly impossible for this to happen! it did happen!! they called me after receiving the vehicle via tow truck and told me the throttle was dirty and needed to be cleaned. So I told them go ahead and then about half hour later they called and said the car needed a throttle position assembly replaced. They had already charged me for the cleaning of the throttle, and then charged me to replace it also. Doesn't cleaning come with replacing the throttle assembly? I think this should be investigated and to see how many other Hyundai's have had this problem. They supposedly contacted Hyundai corporate USA, however, I have yet to hear anything from Hyundai. I really hope all is safe now????.

My car is a 2006 Hyundai Sonata and last night my cars' headlights dim or shut off momentarily, the fan speed seems to drop for a second also but never shuts completely off. I noticed last night my tachometer would only go to a 1 at the lowest. It would go higher as I drove but never back down towards a 0 or 1. You could feel the harsh vibration as I sat at a stoplight while it rested at 1. I also noticed that it feels like the trans is slipping or something as I take off or try to turn. This is the first time I have ever experienced this with this car. This is extremely dangerous!! what if the gas pedal sticks or the lights go out while driving??? I have 2 small children and you bet I would sue or my family would on my behalf if anything happened to us as a result of Hyundai not issuing some kind of recall. Please address this issue ASAP as to avoid any future problems that could have been corrected by a simple recall.
