After having the car for almost 2 years with no problem the engine started to show that it was getting hot. I found that you could make the temperature go up and down just by adjusting the temperature of the ac. The car would run fine then the temp would red line in about 10 seconds and drop back to normal. After this happened a few times I took it to my local Hyundai dealer ship. They changed every thing in the car from the dash cluster to the water sensor and every thing between. After 2.5 weeks they sent an engineer from there manufacturing facility to look at the problem and 2 days later they found the ground bad. I was given a loner car and they took car of all the issues under warranty.

The contact owns a 2006 Hyundai Sonata. While driving at night, the radio and the headlights shut off without warning. The dealer was able to duplicate the failure, but could not provide a remedy. They have inspected the vehicle on five different occasions. The following parts have been replaced: The alternator, fuse box, computer, electrical harness, and the battery. The failure continues to occur. The current mileage is 15,000 and failure mileage was 9,000.

- the contact stated that the 2006 Hyundai Sonata LX, had problems with the transmission slipping. While driving at 10 mph and trying to make a right turn the vehicle started to make a racing roaring noise. This has happened on two occasions. The vehicle continued to go 10 mph, but he couldn't stop it. He applied the brakes, and the vehicle wouldn't stop. The contact sat on the side of the road for a few minutes, turned off the vehicle let it sit. He started the vehicle, and drove home without any problems. The contact did take the vehicle to dealership and they did a diagnostic and found nothing wrong with the vehicle. The contact stated that this has happened on 2 occasions and the dealership did contact the manufacturer. The manufacturer told the dealership to make sure the motor mounts were tightened, and to check and clean all terminals. This was done in January 10, 2007. The contact hasn't had any other problems since. The contact wanted NHTSA to be aware of this problem, he has sent the manufacturer a letter regarding this problem on 01/20/07 and hadn't gotten any response. The current mileage was 7050.

Air bag off light illuminates intermittently when passenger (130+ lbs) is seated properly in front passenger seat, indicating the air bag would not go off. Have had this problem repeatedly and randomly since purchasing the vehicle 9/05, and have requested action at each warranty servicing. (22,500 mi currently) each time the dealer service department claims the diagnostics do not find a problem and the air bag sensor is working properly. They say there are no service bulletins or recalls from Hyundai on this problem. However there are at least 15 complaints on this website about this problem as of 12/06. I am very upset by this apparent lack of caring on Hyundai's part about the safety of their passengers. Just because the intermittent problem can't be reproduced at the dealer's does not mean that the passengers are not experiencing the problem. There has got to be a way to isolate the problem even if it can't be observed in the moment, even if it means replacing the parts in the sequence till the problem goes away.

Bought a 2006 Hyundai Sonata March 18, 2006 at ourisman Hyundai in laurel, md. A week later, March 25, 2006, had to have the car towed back to the dealership because the engine over heated, while in heavy traffic, due to the fans not working. The dealership ordered a fan module and placed it in my car. The dealership allowed me to take another brand new 2006 Sonata as a loaner until my car was fixed. I told the dealership I did not want my car back and to give me another 2006 Sonata. After days of calling back to see if they would, they refused. Picked up my car from the dealership Friday, March 31, 2006. April 18, 2006 bought the car back to the dealership because the A/C was not working. The dealership told me the fans are not working and there is an electrical problem. They are renting a car for me until my car is fixed.
