The engine has always made excessive noise when accelerating. I have since learned that it has been the transmission and is a common problem with the cvt transmission in Nissan Altimas. I feel that given the several thousand dollars it takes to fix that Nissan should either put out a recall or compensate for this as it causes the driver to be stranded one the transmission does eventually fail.
While pulling into a parking place at a restaurant all of a sudden my wife heard a loud noise and surge from the engine propelling the car forward and over an embankment fortunately for a few trees and god's help my wife is thankfully still alive the embankment had approximately 100' drop this has never happened before the sound coming from the engine she still hears, not sure once the car is fixed if we buy another Nissan Altima or even continue to drive this one, something caused this car to surge and it definitely was not her foot,.
