Using keyless entry key fob, all vehicle doors except the driver's side door would lock. Vehicle lights also failed to flash in this scenario. Note this vehicle is just shy of one year of in-service or on-the-road use. Problem was particularly unsettling since vehicle could not be secured by locking making car more susceptible to theft and/or vandalism. Daily vehicle driver continued to use vehicle with this problem until it was brought to dealer for repair after two to three days.
