Hi. My Grand Voyager drives very well except when I hit a long steep hill. The speed drops off and after some time the gears will drop down and the engine will rev up to 5000 RPM. The speed levels out and starts to climb back up. There just seems to be no torque to push the car.
Usally when I've noted this, all 7 seats are taken up albeit with small children 9yrs and under in the back and my wife and I.
Other than the hill issue the car does not seems to have any issues at all. General acceleration seems OK.
