Transmission in park Nissan sent notice truck could roll away. Radio turns self on and off 2-3 times after starting vehicle no lights or messages show up cell phone bluetooth won't work.
Descending my driveway which is an approximately 15 degree slope with the transmission selected to remain in 1st gear, and approximately one third of a tank of fuel or less remaining in the fuel tank the engine seems to momentarily cut out as the vehicle feels like the transmission is in neutral, but the tachometer indicates the engine is running. When this occurs the mil comes on along with the check at light. Stopping the vehicle and restarting the vehicle clears the check at light, but it takes several drive cycles to clear the mil light. This has happened on two occasions. After the first occurrence the dealer checked for any locked in codes, but none were present. Since the mil only stays locked in for a limited time it appears that the on board diagnostics are not storing codes due to it being a momentary issue.
