With only 6762 miles on the odometer, going 79-80 mph on cruise control, the following happened all at once without warning: (1) loud thunk under the hood (2) engine stopped (3) electrical system shut down, including audio, dashboard, and headlights (4) rapid deceleration, as if I had slammed on the brakes (though I had not). (5) approaching the shoulder, I noticed that the power steering and power brakes were also inactive. After putting in park, it miraculously started right back up and got me home. But this is unacceptable, and a very serious safety issue, because the next time it happens, it'll be during rush hour and then I'll get rear-ended by the ubiquitous tailgater, going 70 mph. Even if the brake lights work when I get a chance to apply them, there would still be a delay of a second or two during which the vehicle would be rapidly decelerating on its own, without brake lights. Not to mention the undoubtedly accelerated wear and tear on internal parts.

While traveling at highway speed my vehicle experienced near instant loss of more than 50% engine power with continual lost of the remaining power. Moving from the middle lane into the right lane was difficult and risky during heavy traffic. I was lucky finding a safe spot to pull over. Ambling to the safe spot the engine sputtered, hesitated and reacted very little to any foot action on the throttle, leaving me without the ability to effectively control the vehicle.

I have had 4 instances of what feels like the car slipping out of "drive". while in drive, when I press on accelerator but while the RPM's go up, the car doesn't move.. once I remove my foot and then press again on the accelerator, it proceeds normally. Kia cannot find anything wrong with vehicle but last instance was less than 30 days ago. This is after Kia had to replace the block the first month of ownership of this brand new vehicle.

When pushing on the gas the RPM go up but the car doesn't kick in right away. The transmission? it like you have a manual transmission and you haven't let out on the gas. Doesn't do it all the time, but is doing it about once every time I drive. It is getting more frequent, wondering if its due to cold weather.
