On December 14,2012 I was traveling North up a hill at 35 mph when suddenly they car accelerated to 55 mph. I tried to stop but the cars tires screeched and hit the ladies car in front of me. Thank god no one was injured. The front end is toast. I have to have the car examined and find out why it accelerated out of control and did not stop. The car is a total loss.

On Friday, September 28, 2012 at approximately 9:30am I was pulling into a parking spot at the heb grocery store on I45 at 646 in league city, tx when the engine on my 2001 Hyundai Elantra revved and roared very loudly and surged into the pickup truck parked in the opposite spot. At the time I did not have my foot on either the gas pedal or brake. I stomped on the brake but nothing happened-it just kept revving and surging forward. I shoved the stick into park and luckily it stopped. My car was now in the space the pickup truck had been parked in, and the pickup truck was shoved out into the driving lane between parking sections. I am extremely thankful that no one was in the pickup or walking by or loading groceries nearby and no one was hurt. I was so frightened I was shaking and could barely dial 911 on my cell phone. The pickup had minor damage to its rear bumper, and my car had crushing damage to the front end (hood and bumper crumpled, grille cracked, 1 headlight broken) and a large puff of white smoke poured out briefly (no fire). The police case# is 12-4584 and the state farm insurance claim# is 53-195C-229. The car was towed by aaa to star Toyota collision center at 2112 gulf freeway in league city, tx. I am awaiting their evaluation on the damage and have been told it may be totaled due to the age of the car, although it only has 55,000 miles on it. Even if the car can be repaired, I am worried that the revving could happen again. The internet has numerous sites listing the same type of revving/surging problems with Hyundai Elantras but doesn't list a recall for this problem. What can I do in regards to this scary event" is this a major vehicle problem with this model " I am extremely concerned and would like to hear from you as soon as possible as to what the next step should be to address this issue.

Speedometer does not work in the very cold, sometimes your driving for up to 20 minutes with no speedometer. Its been to the dealer at least 4 times. Once the temperature goes up the speedometer works. They've replaced a sensor, a cable, and the last time they put a new speedometer in. When it's cold the new one does not work either. We left it with them for 4 days, but because the temperature was above freezing they couldn't see it not working so they could not fix it. My daughter goes to school in philadelphia(she drives it) so it works less when she's home in vernon, NJ. Has anyone else had any complaints about a similar problem. There's colder states then New Jersey. Hyundai doesn't seem to have a clue. There was not a specific incident date, it began not working in the winter of 2002 when it had just about 10,000 miles on it.
