Mine did this the night I drove it off the lot. That was September 26th and its been in the shop pretty much since then and is now getting a new transmission. I'm told it will be ready for pickup tomorrow and they're hoping that fixes the issue. RAMCARES is worthless. In my state our lemon law kicks in at 30 days with out the vehicle. Almost there. Luckily I made a cell phone video of what it does. Very dangerous!
