Nice car ruined by severe engine breaking - this is for sedan with auto transmission Edmunds does not have a selection for auto transmission
 Problem with the 328i Steptronic Auto Transmission is the harsh engine breaking when you let up on the gas. At slow speeds, and especially in stop- and-go traffic, the heavy engine braking is enough to get many nauseous as the car does not easily coast to a stop.I have never gotten car sick while driving, but with this car if I drive it in heavy traffic for 30 minutes or so I will get car sick. A BMW Expert told me "I have had a few customers tell me the same thing so I am not surprised of noticing the engine braking."Further, the car emits a very high-pitch sound for about 45 seconds every time you open or close any door or the trunk.Finally, the run flat tires give a harsh ride.
