There are 2 problems which are interrelated 1) when stopped at a stop light the vehicle does not repond when the gas is applied to move forward when the light turns green. Then, the vehicle suddenly lurches into gear. 2) the "d" for drive on the dashboard flashes indicating an error code has been written to the transmission control module. When I took my vehicle in for repair because this was happening the dealership told me that there was no error code on the transmission control module so they do not have a way to diagnois what is happening and that this is a known problem and were advised by the manufacturer to not make any repairs because that may not solve the problem. The dealership indicated the manufacturer felt this may be due to a software problem and may need to complete a software update at some future point in time. However, I've seen posts from other chevy Equinox owners with models dating back to 2014 with this same hesitancy and jerking issue.
