2010 Kia Rio Engine problems

When driving, the car stalls for no reason (there is fuel in the car, has regular oil changes, and a brand new battery). It takes a couple minutes before the car will restart. While on the highway, the engine light will come on and then turn right off, but the rpm gauge stops working even though I am still driving. There is a jerking motion when that happens. This happens on city streets and on the highway. It is becoming unsafe and the dealership cannot replicate the situation. All they do is run the code but...

Took my car to get fixed, and looked at the 2nd cyl.. Apparently, tons of people are having problems with the 2nd cyl. After looking online about it. I had them try all my coils and its not a coil problem. I had all spark plugs changed and tune up was done. There is absolutely no reason my 2nd cyl. To be messed up... ? Kia I'm so disappointed in my car, why are so many problems coming up? My car is not even 5 years old!!! I expect to get answers on this and it be taken care of, I will not be paying for something when I've done my part in maintain g my car. *Tr

We were involved in an accident where we rear ended another vehicle. The other car was at a standstill and we hit them at about 30 mphs. The driver and myself both had seat belts. The driver injuries her left knee. The airbags did not deploy. I think that if they did her knee might not have been injured because she would not have slid forward upon impact.. *Tr

Traffic came to a sudden stop, I could not stop in time. I hit the tires of a semi trailer, that collision threw me down an embankment where I hit a tree head on. The air bags did not deploy. *Tr
