I just tried to install the OBD reader for the Verizon Hum program. I advise against it. My vehicle is undrivable while the Hum Reader is installed. Upon plugging in the OBD reader and starting the car, I received a reduced propulsion error message and engine not available message. All error lights also lit up my display. I immediately, tried the turn the vehicle off and it would not completely shut down. It would return to the initializing start up screen and try to start back up only to have the error messages return. I unplugged the OBD reader and was able to get the vehicle to shut down. Upon starting the vehicle back up (with the reader removed), all of the error codes persisted (I couldn't shift out of park) until I cleared them with a code reader. After clearing the codes, I still couldn't shift out of park so I turned the car off and restarted it allowing it to initialize again and it is back to normal operation. All told, this mishap took 2 hours to fully resolve and get my car back to normal operation.
