We got this car in hopes it would last 3 years. When we drive it, the transmission shudders and acts like it is going to die driving down the road. It is very dangerous and annoying and I'm afraid to drive it. It is really such a shame, the car seems so nice but drives worse than a sherman tank. It seems to do it worse at low speeds, on the military base 15mph 20mph average speed it does it constantly. It also does it on the highway at any speed.
Transmission shudders and makes for a very uneasy, uncomfortable drive. It acts like it is going to die in the middle of driving down the highway.
