Banging sound from under the car when pressing down hard on the gas pedal
I've noticed that this banging sound happens more frequently under colder outside temperature. It's coming from the bottom of the car when I press hard down on the gas pedal. Especially one day when it's only 10 degree F outside, I could hear it as soon as it reaches 10 mph. I don't hear it when the car is totally warmed up though. So I brought it back to the dealership, I left my car there for them to duplicate the sound, but they couldn't hear anything. Does anyone has any of this experience?
