Purchased vehicle 7/29/23 While driving 8/19, vehicle auto-shifted from drive into neutral and the check engine light appeared. I was in the process of accelerating from the on ramp & moving to the left lane. Attempts to return the vehicle to drive were unsuccessful & I coasted to the right shoulder of the highway. The brakes were functional. Once stopped, the vehicle functioned as if it were in accessory mode (radio & power windows working). I was unable to move the vehicle out of neutral to park gear. More lights & error messages flashed on the driver display (I have a video). The on/off button & the light at the neutral gear were flashing. I was able to engage the parking brake & remained in the vehicle on the narrow shoulder on the side of the highway. Tow operator arrived & was able to engage the park gear; however, it would not move back into neutral for him to begin the process to move it onto the rollback for the tow. Attempts were made to disconnect/reconnect the battery & to use the vehicle procedures for a low battery which were unsuccessful. There is an emergency release up under the dash; however, to reach the compartment it's in, the driver's door must be completely open & the operator must be on or near the ground. Due to the speed of the vehicles passing (est 60-70mph, most did not move over to the other lane), it was not safe for him to get into the position necessary to get to the compartment. He therefore had to pull the vehicle up on the rollback without being able to get the vehicle into neutral. At times during his attempts, the engine made a clicking noise and smelled as if something was burning. Fortunately, he was able to deliver it to the dealer where service staff were able to release the emergency cord to move the vehicle to neutral to get it off the rollback. As it was being moved, the engine started clicking again. The dealer's service team plans to look at it 8/21/23.
