Cruise Control problems of the 2012 Kia Motor Forte

I bought a 2012 kia Forte ex hatchback with 60,000 miles about a month ago. Two instances have occurred which I believe might be related. First time I was traveling @ 65mph around a 50mph curve on cruise control. I hit a bump, and cruise control shut off automatically. No big deal, I just put my foot on the gas and reset the cc after the curve. However, yesterday, I was nearing the beginning of a merge ramp to get on the interstate. I was turning and accelerating when I hit a pothole and the engine shut off. Instead of merging onto the interstate, I coasted @ 5-10 mph until I could reach the side of the road. I put the car in park, turned the key off and then immediately started the car back up. There were no warning lights and the car ran like a top. This is a serious safety problem and I am lucky I didn¿t get rear-ended (this was an on/off ramp, so cars were piling up behind me and honking due to my slow speed). I had the car checked by a mechanic before I bought it and he said that although there was no cel, there was a code in the computer for the ¿yaw¿ sensor (he told me if the car runs ok, he wouldn¿t worry about replacing it). Knowing this, I have turned off the electronic stability control in hopes that the issue is related and will not happen again if the esc is off. Car is in good shape and was well taken care of by previous owner.
