My Hyundai makes a clunking noise from the front end. It happens whenever I shift from park to drive/reverse, drive to reverse, and vice versa, and also if I speed up, or slow down quickly. I tried getting the vehicle checked out at a dealer, and I was told "I don't know why, but many of the Elantra's come from factory making that noise, and we don't know why. Obviously, if it was a safety issue, then Hyundai would have issued a recall by now." I was upset by this statement, because it does cause my vehicle to jerk when I am accelerating and breaking, as well as other strange things, so I am concerned that there is a safety issue here. I did buy this vehicle pre-owned, and it has been happening since the day I bought it. I brought the vehicle back to try to get it repaired under warranty, but I was told that there wasn't anything that could be done to fix the issue. I feel really uncomfortable driving my own vehicle when there is something wrong with it, and according to the dealer, there is nothing I can do to resolve this issue.

When driving it is difficult at time to regulate my speed. If I stop at a red light and then try to drive on a green light my car will jolt forward. It is hard to speed up, it feels like my car is stuck in on speed. It makes it difficult to drive on the freeway as it is slow to pick up speed.

Car will not start. Have battery, alternator, and started all tested and are good. Every so often go to start the car and when you turn the key to first position everything turns on. Windows work, radio works, light on dash turn on. Go to start the car and it does nothing. Does not even try to start the starter makes no noise. You just here a clicking noise. Was told be dealer that it might be inhibitor switch (range switch), that was replaced and a week later it again will not try to start. If you let it sit and come back a day later many time it will crank right over. There are many forums online with the same issue from this model.
