2006 Hyundai Sonata Engine cooling Problems

“Oil leaked from valve cover onto alternator. Engine stalled and left me stranded on rural mountain road. Finally got towed home. Mechanic says it will cost nearly $1000 to replace valve cover gaskets and alternator. Car is 2006 Hyundai Sonata with 3.3l 6cyl engine. I believe that this is the same engine and same problem that prompted the recall on 2007 Hyundai veracruz NHTSA campaign number: 14v415000. The existing recall should be expanded to include more Hyundai vehicle models that exhibit the same 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! …”

“My 2006 Sonata v6 started sounding like a diesel when started after sitting for several hours. This clattering sound continues for 4-5 miles before subsiding. This started when the car had approx. 25,000 mi. I have had it in two different dealers for a total of 6 times. They changed the timing belt tensioner a couple of times, changed an AC reed valve, and last time replaced the valve lifters, which they said were badly worn. None of these efforts fixed the problem. It continues to get worse. I am taking it in again this week for try #7.”

“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!! …”

“Good morning! I am having problems with my Sonata and I need assistance and advise. My vehicle has broke down with me on 3 occasions with the same problem. I am concerned because my warranty will be running out at 60,000 miles and I am concerned about my safety. The belt that goes from the A/C to the motor and the alternator continues to fray and burn up in pieces. At this point the car is inoperable. I was told by the Hyundai dealership that they have replaced these belts with chain belts on the new Sonata's because of this problem. …”
