While driving cruising at 45mph all of a sudden the vehicle felt like it went into neutral and the rpms went up to 4000 when left of the gas and gave it gas shifted back into gear. Also when you go up a hill and get to cruising speed the vehicle hangs in low gear and high rpms when let off it will up shift this is an intermittent problem. Took it to dealer 3 times on the 3rd time they kept it overnight and the mechanic finally felt it and agreed it "hangs in gear" he said "does not kick down smoothly and seems like the tcm is confused and takes awhile to decide what gear to go into". He also say " it seems worse in active eco mode and when he shifts it manually it seems fine". There has been a significant reduction in gas mileage.
