Re- 2001 Hyundai Sonata I was on way to work going 93 North towards boston 1 exit away from work when I went over 3 small bumps on highway nothing out of the ordinary, yet my tires felt as if they were not stable I was only going 60 slowed down to 30 took off ramp 1 block away from work, then completely stopped at a cross street intersection to take a right. I proceeded then I flew forward in my car. My car stopped short for a second I thought I hit my shifter in neutral or reverse, that was not the case, I was in drive. Put car in park it made a searing ungodly sound I didn't know what was happening. I got out of my car just as two men came running over to help me. We noticed the tire completely against inside wheel frame. I just had a rim replaced not even 1 month ago and new brakes and tires yet I wasn't sure what this tire like that meant. I couldn't understand why I seem to be having to replace so many things, one right after another, however I was told after towing car to Firestone that my whole car undercarriage frame subframe is completely rotted and that the axle is snapped and may even have damaged transmission I called Hyundai to put a complaint in. They told me I have a recall on my car when they looked up my car by the VIN yet I was never notified. They seemed quite caring and empathic to my situation, yet the last question they asked me, blew me away. Christine the operator from Hyundai asked me one more question Ms. __ what do you plan to get out of this" are you kidding me" what a question, I asked if I should get a lawyer, and was it an voluntary or involuntary recall she said that Hyundai put this recall into effects after the company realized and found that they may have a defective corrosive situation, yet on the web they were obviously investigated first then did something about it. She said recalls started in July of 09 and are still being issued to date, she said she'd mail me a packet to fill out and send back -oh joy!! cant wait.

: the contact stated while driving various speeds, the automatic transmission shifted gears erratically and the vehicle operated at a reduced speed without warning. The vehicle was inspected by a dealer, who determined the input speed sensor of the automatic transmission needed to be replaced. The manufacturer was not alerted.

I got my car in 2002 it is a 2001 sonota. When you push the gas to pull out in front of traffic this car doesn't want to go! I have almost been in several car accidents when I tell the dealership about the problem they tell me nothing is wrong! also if you look at the complaints you will see that the air bag light keeps coming on that is a safety problem in its self.

On April 28, 2001 I and three other passengers were riding in the vehicle. I was traveling down a long grade at 35 to 40 miles per hour. Toward the bottom of the grade the road curves to the right and at the bottom there is a traffic signal. When I came around the curve I saw that the light was green and proceeded to accelerate in order to get up the approaching upgrade. When I attempted to accelerate the engine revved very high but the vehicle continued to slow down. Tansmission had shifted into neutral although the shifter still indicated that I was in drive. The vehicle would not automatically shift out of neutral. I had to manually shift into low gear. Two days later I took the vehicle to the dealer and, after three days, I was told that they could find nothing wrong and that they would make no repairs. On Friday May 4, 2001 I was contacted by the Hyundai regional service representative who tried to convince me that there is nothing the matter with my vehicle. He told me that it was the vehicles "adaptive learning" feature that caused the shift and that what I experienced was perfectly normal. I find it very hard to believe that the new car I own was designed to shift and stay in neutral when it is in a situation where acceleration is necessary. Both the dealer and the manufactuer continue to insist that there is nothing the matter with the vehicle and refuse to make any repairs. Also, one week before the incident, my wife and I were on the same road and the vehicle did nearly the same thing. The only difference was that after about a second or two of stepping on the gas pedal transmission shifted itself back from neutral into drive. Please help.
