Cruise Control problems of the 2015 Jeep Renegade

Hard shifts in the first few gears ( hard jurks) and also clunks. . When moving shifter into and out of park, nuterual, reverse and drive it clunks. . Hesitates to shift when stopped or slow moving. When on highway has alot of dragged has hard time keeping speed and when passing it take the vehicle few seconds to speed up, have to push peddle to the floor and after few seconds it finally speeds up. In cruise control its constantly having a hard time keeping its speed constantly jumping into higher gears to catch up to the set cruise setting. Every time I take it to the shop and ask whats going on they say its how the Jeep Renegade was made, its normal for it to do all this.

I purchased my 2015 Renegade latitude 6-speed manual transmission vehicle last fall and found that from the beginning at times I had difficulty getting it into gear. I've been driving manual transmission cars (all sedans until this) for nearly 35 + years so I'm familiar with how to shift etc. I knew and expected that there'd be a learning curve as every vehicle is different. But by now it should be resolved. Instead, it has worsened. I have maneuvered around the minor problems -those at lower speeds-having to downshift a few times when I needed to upshift (I rely on sound and the rpms as my guide). The car now has 6200 miles on it (a mix of back road driving with suburban streets and some highway) and it is now revving uncontrollably at times, throwing me out of cruise control, acting as if on ice when there is none, surging forward when I haven't accelerated. And the advertised 31/27 mpg has not happened. I am now down to 23 mpg. I will be dropping it off tomorrow for an oil change and for them to look at this revving problem and the low mpg. I am afraid to drive this car, which I love very much, aside from the problems btw. I am concerned because I see that there have been complaints listed on sites about just this thing and it is a reminder of the out of control acceleration problems of cars in years past (like with Audi). Please let me know what to do besides taking it into the shop. I see below that you ask when this happened: as I said, from the beginning-I noticed that when I backed out of my driveway and put it into first and then shifted into 2nd, I'd have to go back to first. Then, it would surge ahead as if it were in third or fourth. That has continued. . The scary issue is the revving in traffic last week. I have not driven it since then.
