The vehicle would make noises and stalls during accelerations and decelerations. It would struggle to shift into gear, especially from 1st to 2nd gear. When the vehicle comes to a stop at traffic lights or stop signs, it’s really hard to get the car to move when accelerating. In high speed on the highway, the vehicle would struggle to increase speed when accelerating and the vehicle would automatically slow down and get weighted down. This would result in having to pull over. Sometimes, the vehicle would not be able to be put into Park, and automatically shifts to Neutral not allowing it to be put into Park mode. When attempting to put it back onto Drive, the vehicle would not go and emission and transmission warning would start flashing. The majority of the time, the emission or transmission warnings would not flash. This is very frightening because I was not able to control the speed of the vehicle, and luckily when the car automatically shift to N and came to a stop, I was able to pullover to the side of the busy highway right on time. The car has been inspected for the same issues in the last 3-4 years by the dealership for the same problem. The transmission fluid got changed and that was all. Now it’s happening again.
