2017.5 Frontier SV 4x4 king cab. Automatic V6. 35000mi. Vibration from day one. Also wonders on highway. On wet road it feels dangerous and will fishtail/hydroplan. Dealer alignment at least 2x, rotate tires every 5-7k, balanced tires many, many times now. Also went to independent shop where it was checked out and road tested. All say everything looks good but they do feel a Vibration. Don't know why. Tires are getting worn but it's a problem from the beginning. Add weight in bed with no difference. So biggest issue is the wondering it feels very bad on wet road especially with north country winters. Speed not issue,cars and trucks flying by me giving me dirty looks. Any help would be appreciated. Planned on keeping truck along time but something is not right.
