Thank you all for sharing.
So two of you changed the stock tires and mention "very good" and "like a dream" performance afterwards. I too thought this might be the reason for my experience, but wanted to eliminate other possibilities before spending the money.
Some mention driver ability, common sense, adapting to the vehicle, and environment. I rate my driving abilities as second only to hard core driving enthusiasts. This is my 36th winter driving in snow. Over the years I've adapted to eight different cars (most FWD, some RWD, none AWD). Throughout all of this I continue to earn accident-free auto insurance discounts.
Four of you rate your experiences with snow driving using the stock tires as "little problem", "favorable overall", "great", and "no problem": This would seem to indicate that the Journey in proper mechanical condition, and it's stock tires, aren't the problem.
It is possible that there is something wrong with mine that the dealer did not see. Does anyone know what type of mechanical change and/or malfunction could cause this poor handling in the snow?
