so on 12-5-2011 we get our first freezing snow storm here in Albuquerque, NM. no biggy right as I have all wheel drive. my son & I go to Bank as roads are clear, it's just cold as hell. we take off & about after 1 mile the SRT8 just starts to vibrate. I mean the whole jeep is just vibrating, so were like wth. I turn off everything, radio, heater, butt warmer, as we try to listen & figure where is vibration coming from. we jump on freeway and head to Bank, as SRT8 stil drives fine, just vibrating. we leave the Bank & I notice that vibration is gone, completely gone....:thinkerg: has this happened to anyone else?
