I personally think the 2015 and 2016 CR-V's represent a sweet spot for those who are wanting a well-designed, dependable SUV. They don't have all the technology that is available in the newer models but to the best of my knowledge there haven't been any issues with gas in the oil or a lack of heat in the cabin.
From what I understand the vibration issue was either there or it wasn't. Take an extended test drive and see for yourself if this particular CR-V has more vibration than you believe is tolerable. I test drove both 2015 and 2016 models before finding a deal on a 2016 and moving forward with my purchase. I didn't note any significant vibration on either year of the ones I test drove.
Pick up a well-maintained used model and enjoy the initial savings in both the purchase price as well as the ongoing expenses associated with ownership.
