Description of the problem | Bought 2 brand new sonata with top technology package on 4/15/2015. The problem happened on both new cars. Whenever the gas pedal is off, the computer/software take control of slowing the car down even with open road ahead, on flat surface, on corners, up or down hill. This happened whether it is in eco, nor or pwr driving mode. At various stages, the brake kicks in at various speed and the transmission downshift prematurely; in deceleration, the rpm will only goes down until idling speed, but i can see the rpm goes up a few hundred rpm at least twice before the sonata come to a complete stop? Sonata does not have "hill decent control" like the range rover for specific safety reasons. In cruise control, it is even worst. If you set cruise at 60, later speed up to 80 to pass a slower car, once you let off the gas pedal, the car hit the brake and slow you back to 60? What is the hurry? Coasting is drivers best friend because it means free mileage. Yet sonata engineer thinks otherwise. This erratic behavior would certainly irritate the driver behind you enough and even cause road rage. If the sonata decided to hit the brake by itself at a fast corner, what will happened? There is an article in detroit bureau mark b, said his 2012 equus spin out of control and no one understand why? I brought back the car twice to the dealer and both the mechanic and the sale manager defend their product. Attach article from detroit bureau. Http://www. Thedetroitbureau.
