When vehicle is put into reverse, there is a 15-20 second delay before reverse kicks in. You don't know when it is reverse yet , you let go of brakes and vehicle moves forward until transmission engages. Have taken vehicle to dealer to have checked out and ford and dealer says normal delay. Very unsafe not knowing when reverse kicks in, I have rolled forward into garage when ready to back out. No warnings come on about transmission. This started as soon as i bought the vehicle.
