When iphone connected the stereo randomly skips. And when my wife got out of the car the stereo wouldn't shut off. Also took car in to dealership multiple times due to leaking radiator fluid. Fixed gasket but still smell radiator fluid when you have car running awhile. Also engine makes terrible knocking noise like a litter issue when you start the car up. It lasts about 10-15 seconds.
