On Saturday I noticed that my Jeep felt sluggish. I have to press the gas pedal a little harder to get her moving. Any ideas what this can be? She is a 2012 Rubi auto with 4.10 gears, stock suspension and tires. Almost 31k miles on the odometer. It feels like the hand brake is engaged while driving but its all the way down. The engine isn't sputtering or anything like that. It just feels like some sort of resistance. Another analogy would be it feels like there is some twine wrapping itself around the axles causing it to slow down. I have a feeling my hand brake might be engaged even though its not engaged but any help would be appreciated.
