Emission Control Problems of Hyundai Sonata

I was driven on the highway in the 2nd to left lane about 70 mph, check engine light was on and all of the sudden I lost complete control of the accelerator pedal. I pushed it all the way down to the floor several times, no pressure, no control and obviously slowed down. I moved over to get to the right shoulder to stop and see what is the issue, luckily the brakes worked, but many cars were dodging me trying not to hit me. I didn't get in an accident, but sure close to being in one and high speeds. Frightening to say the least. I did make it to the dealer and come to find it is an emission part that failed that caused the car not to accelerate. I did get it fixed but was out of warranty, and past the federal emission reimbursement program of 8 years or 80k miles. I had about 80,200-500 miles on the car. Coincidence, don't know, I am still concerned driving the car, it could happen again! I am just glad I didn't get seriously injured or killed. I didn't get reimbursed for the part that cost $1,500. But I am very concerned knowing that this could happen to anyone with emission controls by the computer in your car. I tried to be proactive therefore the post complaint for others. I guess it takes collateral damage of people losing life for car companies and the wonderful federal government to take notice. Beware most new cars have these systems from what I am told.

Lower oxygen sensor malfunctioned, causing the "check engine" light to stay on. I have been returning to the suntrup dealership in missouri every since I purchased the car for the same exact problem. And the problem is always the oxygen sensors. I have a 2001 Hyundai Sonata and I have been having the same problems over and over. I had an extended warranty that I purchased with the car for $1,300. 00 and I find out on my last visit to the dealership that the warranty company filed bankruptcy. So now I have no warranty on my car and I have lost money for no reason.
