Today, while pulling out onto the highway my car would not accelerate properly almost causing a very severe accident with my 8 week old baby in the car. We continued to try and drive so we wouldn't be stuck in the middle of the highway but the Jeep went 35 to 40 miles an hour all the way home. This was not the first incident with this car but the first as severe as this. A few days after I bought the car it would shift hard when put into reverse, it felt as if someone hit me from behind. This is a brand new vehicle, my only vehicle, and I am scared to take my baby anywhere. This was a very scary incident especially with a newborn. Jeep not only put my life at jeopardy but more importantly a baby's life!

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.

The 2015 Jeep Renegade has had about 800 miles when the problem appeared. I was driving on a freeway at 70 mph. All the sudden, the car started jerking and the car would not accelerate even when I push the pedal as I intended. So I got off the freeway and started driving local at lower speed, and the car was acting even more weird. The car was jerking and came to stop. The engine was on but the car would not go. Luckily, it was at night time and in residential area, there were only few cars around so they could drive around. I changed the automatic mode, 'd', to the semi-manual mode. The frequency of the jerking reduced but the car came to a stop again while I was driving about 6 miles to drop the car at a repair shop at a mfg authorized dealership. This could have caused serious property damage and bodily harm. I was lucky that there were many cars around at the time and the car did not stall on the freeway. I am not an expert, but the problem seemed to be related to the power train (and speed control possibly.) I hope I am the only person with the problem. This problem must be assessed and appropriate action needs to be taken. My car is currently at a repair shop and will be assessed, hopefully tomorrow.

My transmission had been slipping in the lower gears, and especially when I turned corners. Finally the car got stuck in 5th gear, and barely goes when I hit the gas. Both the transmission and engine light came on. I am taking it in.

I purchased the car brand new and had it for 6 days. We drove from denver to breckinridge. We were coming down the mountain when the car shut off going 70 miles an hour. At one point the hydraulics went out and the brakes did not work. We pulled the car over to the side of the road. It took about 10 minutes to start up the car again. We proceeded on, thinking it was something with the altitude and was a fluke. No, it happened to us again. The same thing. The car shut off again going 70 and the brakes didn't work. It was terrifying. The car was towed back to the dealership. It needs a new transmission and associated parts, on a new car with 400 miles. If this was in the winter and the roads were icy, my family and I would have been dead.
