general problems of the 2008 Kia Motor Spectra

My car is revving, even in park. If it occurs while driving, the brakes are hard to push as well.

Intermittingly, after starting the vehicle, engine begins revving. Intermittingly, while slowing & stopping at a traffic light, engine begins revving and attempts to lurch forward. I have to press the break very hard to keep vehicle from moving forward. Fred anderson kia, raleigh, nc investigated this problem on 7/10/15 but was unable to recreate the problem. They re-cleaned the throttle body. The issue has continued on and off since then. On 8/20/15, after approximately 45 minutes of highway driving, I pulled into the parking lot at work. I put the car into reverse to back into a parking spot & the engine started revving dramatically & the car jerked noticeably as it went into gear. I backed into the spot & put the car in park, again jerking. I let the car idle for a few minutes & moved it in & out of gear. The revving worsened, the car attempted to lurch forward even with both the break & emergency break & continued jerking with every gear change. I have an appt. On 8/21/15 with fred anderson kia to investigate. My concern is the safety of the vehicle, as I have seen an indication of the same problem with other kia vehicles on this site & other sites. It seems as if kia is not resolving the issue and I don't want to have an accident because of it.

Vehicle surges while driving and/or while stopped in traffic.
