**************************engine will shutoff without warning********************** it has happened with various levels of gas, various weather conditions, and both while stopped and moving. The "check fuel filler inlet" light will come on. Sometimes, the check engine light will remain on, but will clear within the next startup or two. Car has been at dealers at least 4 times for issue. Engine throttle body and crankshaft sensors have been replaced. In the beginning, the vehicle would do this once or twice, then run perfectly for months at a time. Each time it is "fixed" by dealer, who claims they cannot replicate the problem. Lately it will stall 4-6 times within a 30 minute period. Last month, I was able to read code 2107. Today, it stalled again 6 times, no check engine light remains, no code to be read. When car is running normally, it sometimes hiccups and seems to run rough.

My transmission jerks as I accelerate during travel. To me it's getting worse. I have had it looked at. No codes are showing that I have a problem. But clearly something is wrong. I have done this several times, still no codes to indicate anything is wrong with my vehicle. Also my gas sensors are shot. Engine light goes in and out. My vehicle has stopped in the middle of atlanta traffic, causing problems of other vehicles traveling in the direction that I am with children. I also have the problem with backing my vehicle, it jerks before backing.
