I purchased my new car on 02/09/04 at bronx Hyundai. It is a 4-wheel drive 3.5 ltr engine Hyundai Santa Fe. Upon driving I felt a hard knocking-vibrating sound when I drive on local (dry) streets and then a feeling that the car jumps (lunge forwards)after I stop. On several occasions I thought someone hit me from behind. This continues to happen only when I drive locally. The car has never done this on the highway, which is part of my daily commute. I wasn't sure why at first, the car did that and I thought it was part of the tracking control system(4-wheel drive even though the road conditions were dry. In every incident, the car feels like it is not going to stop, but it does. I am afraid because when the car jumps and if I get too close to someone it can hit a car in front of me, or even a person crossing. So, I was happy receive my recall notice stating the exact problem I was going through I then called and took the car to the dealer and told them what was happening. I hoped the programming would work since my problem was similar to the recall symptoms. That is when this nightmare began and it was on April 9, 2004. Since then, the dealer has been very cooperative but they seem at a loss also. My car was programmed twice and then the ABS sensor replaced and a chip also(this was done last Monday). I have taken my car 5 times as of today. My car continues to do the knocking/grinding sound and on 2 occasions the last being on May 29; the ABS, tcs and the 4-wheel drive lights on the interior control panel have flickered and stayed on as well. (when this happened my car did the knocking/vibrating noise as well.) it has become a daily occurance so now I am documenting all of my incidents and I am getting afraid to drive my car. So today I gave my car back to the dealer and they told me that they will contact the main office at Hyundai. All parts and service were not charged and replaced with new Hyundai parts.
