Transmission Suddenly Downshifting!

I am sorry to report a transmission problem with my brand new Jeep Grand Cherokee Overland (Gas V6). About three times now, while we are driving at about 30 mph, the jeep on its own will drastically downshift causing a sudden slow-down which has caused people following us to slam on their brakes to avoid a collision. I have read about this sort of transmission problems in older vehicles, but has anybody seen this with a brand new 2015 with about 1000 miles on it? :mad::(

Immediately take you Jeep to the dealer!

If your Jeep has ACC/FCW, check the domed lens cover of the radar, which is centered below the front bumper for dirt. Clean the lens often.

Thanks, we are bringing it in today. Dealer was responsive and will supply a loaner. Yes, my Jeep does have ACC/FCW but this is more of a downshift with the motor RPM going very high with the associated deceleration of the vehicle. Car was cleaned a few days ago.....but I can check the lens
I will keep the group posted...
