When from a full stop, then with when needing to accelerate quickly, there is a delay in engine response. Usually half a second to one full second delay in engine response before it starts to accelerate. One one occasion, it did not accelerate at all. I had to then let my foot off of the gas pedal and press down on the gas again for it to finally accelerate. This was very dangerous for example when I was on the freeway. My lane was stop-and-go traffic, but the lane to my right was open, so I waited till it was clear then turn the steering wheel to the right and press the gas pedal. Well to my surprise it did not accelerate and consistently moved around 5 mph, well there was a car coming in that lane and my car would not accelerate so I let off my foot and press the gas again and it started to accelerate.

Engine shut down in traffic and would not come out of drive. Mazda dealer service told me to disconnect battery to reset system. I think this is safety issue. Please contact me with answer
