A 2014 is still under warranty. I'd have it replaced if it is giving you trouble. I'm not sure if it is possible, but there is a touch screen that is hardwired on a lot of the new highlifes, that works the same, but isn't a remote. I'm not positive it can be retrofitted or now.
There are like 25 different channels that you can set that thing on to make sure you find one with no interference, sometimes it's not the remote at all, but the channel it is on. Mine works flawlessly on channel 24. It's not quite enough to just swap out the panel, pairing it correctly is the key.
