Since you say the liftgate does operate fine using the "rear" key fob button, this rules out any type of issue with the liftage's switch, actuator, motor or wiring. It must be something with the key fob / transmitter. I would suggest resynchronizing your transmitter. To do this, stand close to your vehicle and press and hold the lock and unlock buttons on the transmitter at the same time for 15 seconds. The door locks should cycle to confirm synchronization. If the locks do not cycle, it would be best to contact local dealer for issues with the transmitter.
