My own Grizzly experience started 5 wks ago, after concluding (as did buddy who bought one same day at another dealer having one stock) that for me, 2017 Grizz offered best combo of equipment, preferred color of matte silver plus Yamaha promos (winch or extended YES). I bought mine at $8399 (vs $10,299 MSRP) plus reasonable freight, dealer prep plus applicable tax and fees added to that.
Being new to ATVs, my own research prior to purchase was combo of having owned multiple Yamaha street motos over many decades using this forum and other websites. Unsure what issues there were in 2016 other than as-stated, but my 2017 Grizz (and buddy's) runs and performs stellar.
Enjoy your 2016 Grizz or perhaps keep shopping, depending on the deal you scored...
