First time occurrence; I am the first time owner and bought my car new. Approximately 1 year and 3 months of ownership. Attempted to merge onto the freeway. Going about 55 mph and attempted to advance to 65 mph. Rpms increased to about 4500-5500 but no speed increase. Vehicle made a erving engine sound. Flashing check engine light them came on and again so speed increase with pressing the gas pedal. Car then started slowing down as it was not responding to my foot on the gas. Had to merge onto the side of the road, turn the vehicle off then back on.
