NHTSA complaint #11765829

Owner complaint summary

While driving on the expressway during rush-hour traffic, multiple warning lights illuminated on the dashboard and several error messages appeared. At the same time, the vehicle began repeatedly jerking while I was traveling at low speed in heavy traffic. I continued driving for approximately 10 seconds, but the jerking continued. Because of the unusual vehicle behavior and the warning messages, I pulled over to the side of the road. After stopping, I attempted to shift the transmission into Park, but the vehicle would not allow me to change the gear. I turned the engine off and restarted the vehicle, but I was still unable to shift the vehicle into Drive. I attempted this three times. On the third attempt, the vehicle finally allowed me to shift into Drive, but the check engine light remained illuminated. I subsequently took the vehicle to the dealership for inspection. The dealership stated that they updated the vehicle's software and reset the error codes. I am reporting this incident because the vehicle unexpectedly began jerking in heavy traffic, displayed multiple warning/error messages, and temporarily prevented me from changing the transmission gear. The inability to shift the vehicle normally and the sudden jerking created a potentially dangerous situation while driving on the expressway.
