Hello all, I'm hoping to get some insight on my brand new Cherokee overland purchased 3 weeks ago. 750 miles on it now and I am just starting to get used to this thing. However, I am concerned about my transmission. I cannot for the life of me get this car to get into a passing gear or even accelerate for that matter. It's fine around town. Once you're merging onto a freeway or needing to pass you can floor it and it almost just stays the same speed. Regardless of "eco mode" "standard mode" or "sport mode". This is my first jeep and I'm not expecting a lot of horse power with a v6. It has the 8 gear transmission and I'm just wondering, Does anyone else experience this with their jeep? I cant tell a difference between any of the modes and it's like the Ebrake is on ALL THE WAY when you floor it. Any insight would be helpful. Thanksnin advanced.
