Driver's side headrest rises approx. 2-1/2 to 3 inches from lowest position during the normal course of driving. I do not adjust the height of the headrest, ever, other than to correct this unusual phenomenon. This happens constantly and repeatedly in as little as 10-15 miles driving over paved, smooth roads while driving speeds ranging from 45-75mph. Has happened sporadically since we purchased the vehicle new, but happens regularly and consistently now. Interestingly, this same phenomenon has occurred with other Toyota I purchased new, namely my 2006 corolla and 2008 corolla le. Never thought about it being a potential safety issue until I saw it recurring on my 2017 Rav4. Dealer is experimenting on fix by replacing adjustment buttons on both driver and passenger seats, at my expense (just returned from long road trip and took vehicle to Toyota at 264 miles past end of 36K warranty) but could not have serviced on the road. Unfortunately, dealer informed me that this is only the beginning of the investigation process to determine the cause of the problem and may involve more extensive work (also at my expense) if button replacement does not work.
