Was driving and all of a sudden my rpms started to jump but car wasn't moving any fasster. Drive is running like if it were in Neutral. I had to drive the last few blocks home in 2. I did the ignition trick and saw the codes P0700 and P1685. Anyone know what those mean? What could be wrong? I have the 7/70k powertrain warranty offered by Jeep when I bought mine and just this last Thursday purchased the Max Care warranty but haven't received paperwork yet. My car is literally 3yrs and 10days old and only has about 27k miles.
