Starter Solenoid problems of the 2007 Kia Motor Spectra

I was driving on the interstate about 65 mph. All of sudden, the car lost all forward motion power. When I pressed the gas, the rpms increased, but the car did not get any power. The engine continued to run without problem. After stopping on the shoulder, I put the car in park and turned off the engine. After starting again, I put the car in drive, the forward power was working again and the car shifted fine. Transmission fluid was changed at 110,000 miles. Suspecting transmission, I took to a transmission specialist. I was given the following information: error code p0750 shift solenoid; error code p0755 shift solenoid b; error code p0760 shift solenoid c; error code p0765 shift solenoid d. Was given price quote to fix, but encouraged to contact kia dealership about problem as they had seen this before on other similar kia Spectras. Called dealership to inform them of problem. Left message, but never got a return call; and the one time I got a person, I was told that they would have someone from service call me back. Never heard from anyone. On may 16, 2015, the same thing happened, only this time turning the car off did not work and the check engine light came on. I was able to disconnect the battery and reconnect, then the car shifted again. Has anyone else had this problem? is there a recall? before I spend $2000, I want to know if kia is avoiding my calls because they know there is problem? did internet search and have found similar complaints.

Owner noticed smoke coming from underneath the hood while driving, vehicle quit moving and would not restart. Upon inspection, the ign 2 30 amp fusible link located in the engine compartment fuse box was blown and the starter solenoid, located on the starter, was melted. It was discovered that there was no factory circuit protection between the battery and the starter solenoid. It is speculated that the ignition switch became stuck in the start position and melted the starter solenoid due to continuous starter operation after the initial start until melting and smoke occurred. While there was no fire this time, the absence of circuit protection on this circuit poses a serious risk because this wire runs from the battery, over the transmission, and up behind the engine, ultimately to the starter solenoid. There are many places where this wire could rub and wear off the insulation over time, causing a short to ground directly to the battery with no circuit protection.
