“I purchased the vehicle used in 12/2005 from a non-Hyundai dealer. I began to notice that the car periodically did not shut off immediately when the key is turned to the off position.

A year later, the vehicle was taken to another service dealer who could not determine the cause of the problem. The manufacturer was not notified. Updated 10/25/2006 -”

“2005 Hyundai Sonata, engine in this car was meant to be in the elantra which is a much smaller and lighter car, but when put 4 cylinder engine in a Sonata which is a heaver and larger car, even though engine operates to the spec, other problems are evident which the dealer and the manufacturer failed to tell the consumer, now this car idles so bad it is worse than a truck when car is in drive and stopped at light etc.”
