I was driving down a busy street in stop and go traffic. While stopped at a stop light, my vehicle made a very loud "clunk" noise, lurched forward and the check engine light came on. When I attempted to accelerate after the light turned green, I had to push the gas pedal almost to the floor to get the vehicle to move forward. I pulled over and parked, turned the vehicle off, waited about a minute, turned the vehicle back on, and the problem had gone away although the check engine light was still on. A day or so later, while I was driving on the highway going approximately 65 miles per hour, the vehicle made the "clunk" noise, lurched forward and the check engine light came on again. This time, because I was already in motion, the rpms jumped up above 3000, which is very high for a 4 cylinder engine only going 65 miles per hour. Again, I pulled over, turned the vehicle off, waited about a minute, turned the car on and was able to drive the vehicle normally again although the check engine light remained illuminated. This issue has been happening randomly about 20 times a year over the course of the last 2 1/2 - 3 years.

My family and I were going down the road and there was a weird noise and the engine started to rev up and the speedometer was going down to 30 miles an hour, at the same time the RPM"s were going higher. I pulled to the side of the road because the shift gage on the instrument panel was flashing weird. It had a d with a line thru it. We had to shift it manually from 1st gear up to drive. It was scary since there was a truck with a trailer behind me coming up fast. It has done this to us twice in the last two weeks.I have seen that there are other people having the same problem or similar. Something should be done. When we have a warranty we still shouldn't have to pay a deductible for some problem with this brand car" power train and speed control sensors. Going out and needing to be replaced.

While sitting at a stop sign, I decided I was a little to far into the road. I shifted into reverse and noticed it shifted really hard. I put it into drive and pulled out onto the road - again it shifted hard. When trying to speed up, the car wouldn't shift out of 1st gear, the check engine light came on and I couldn't speed up. I've been told it is a bad transmission range sensor.

I noticed my car having difficulty accelerating and it would occasionally feel the engine jump while driving. The check engine light was on. I was going down the interstate when the engine shut itself off. Luckily it turned itself back on and I was able to safely accelerate to speed. The shop said that it was the transmission range sensor and the transmission control sensor. A year ago the car was displaying funny symbols and would not start occasionally. Again the same sensors had to be replaced. A third time the car check engine light came on and the car was again having difficulty accelerating. The acceleration issue and the light are intermittent, it has now again begun doing the engine "jump" it is scary being at a light and not being able to move. It is very scary stopping to turn left into my apartment complex and not knowing if my car will respond when I have a gap in traffic to turn. Took it to a shop today to find out that the codes from the engine check light are again the transmission range sensor and the transmission control sensor. The car has under 65k and I have had these issues three times. I am thankful that it has not caused a major accident.
