Noises During Shifting problems of the 2011 Kia Motor Sportage

So I had pretty much a full day of driving and my manual transmission 6 speed 2011 Sportage, that until today the only problem I noticed was that sometimes to me it felt like when I up shifted or began to go into first that it wasn't going all the way into gear; and at times on the highway it wasnt accelerating normally and my gas mileage is about 50m less per tank than it has been the past 5 mo. (financed to buy as of March). According to the dealership only 1 previous owner and I'm not sure what work had been on it prior to the dealership we are buying through. So today car use in town running completely normal since 11am then suddenly around 6:30 started making all kinds of noise to me a knocking sound plus an almost like revving sound mixed in. We came straight to a gas station and checked the oil with yellow dipstick, as we are almost due for a change, added about a half a quart and started it again to run the oil thru and same sounds but louder. We then turned it back off called a mechanic friend and he came and said without taking anything apart he felt it could b a rod. I then called my mom to come pick up my 3 young kids with me to take them to her house out of the TX heat while we attempt driving home. Started it up again around 8:30 to head the half mile home and very faintly could hear still a knocking and accelerated slowly. Im mot a car genius or anything but not knowing the vehicles personal history prior to March of this year I am worried to drive on highway the 40-50 mile distance to get to the nearest kia workshop. I absolutely loved my soccer mom car until today and now im afrraid to drive it after reading the recalls. Is my vehicle a part of any recall? my clutch it new and my fuel pump as well according to the dealership we are buying through so I know it isnt that. Just want to feel safe and have my commute back to normal again. . . What's going on??.

We have had our car in to be serviced five times and the problems are still not fixed. The first problem was that it was randomly hesitating and there were a few times we almost were in an accident because the car would not accelerate. On one occasion the car would not go past 40mph with the gas pedal floored, we took it in and were eventually told that the problem was fixed, after my husband provided a few service bulletins to the aloha kia service dept. (on our second trip in) each time we have had our car "fixed" the problems have returned with more problems sometimes immediately after, sometimes in a day or two. We have yet to be told what is wrong. The following are problems we are experiencing: randomly not accelerating, the vehicle locking up in park, loss of power, a rolling feeling while driving, whining noise, grating feeling in steering and gas pedal, shifting is really loud and takes longer than it should, brakes are not reliable sometimes there is little resistance in the pedal, we are getting 200 miles to the tank, you can feel a pattern of bumps while driving it is like smooth bump smooth bump bump smooth bump etc. . . ( I do not know how else to describe it and we have not been told what is wrong) on the last occasion my car was serviced I was told everything was fixed and all of the problems tied into the brake system, the computer had to "re-learn" what it should know. I drove for three miles before experiencing the problems again, and they are getting worse. I feel the service dept. Does not want to address the real problem, there is a terrible defect with a major component(s) of this car. I have taken video of my instrument panel while driving to reflect the irregular shifting.
