From a stopped position there is delay when the accelerator pedal is pressed before the engine actually begins to accelerate. The delay is approximately 2 seconds and presents serious danger when attempting to pull into approaching traffic. I have had a few close calls where I was almost hit by another vehicle because of the significant hesitation with the acceleration. I have taken the vehicle to the dealer a few times, but they said they could not find any problem and no error faults had been logged in the vehicles computer. The problem was intermittent initially but is not consistently occurring. I believe this is a serious safety issue and suspect my case is not unique.
