  The headlights did not come on automatically when the vehicle was started; it was after 9 pm and completely dark. The headlights would not come on even when the switch was used. I had to drive home using the high beams. The headlights did come on after I had gotten home, turned the vehicle off, waited approximately 15 minutes, and then started it again. This has occurred multiple times. on a separate occasion, during a heavy downpour in rush hour traffic the windshield wipers stopped working. I was able to get off the highway and park to wait out the rain. I turned the vehicle off and waited about 20 minutes. The wipers began working at that time. this last issue has now occurred twice. I have parked, turned off the engine and gone inside the store for less than 5 minutes. When I try to start the engine, it will not turn over (no sound at all). I turn the radio off, wait a minute or two, and then when I try again; it starts as if there wasn't ever an issue. *tr

  Exterior lighting

  I was driving at night and the headlights went out. Everything else was working, I had dash board lights. The high beams work fine but not the low beams. Took it to the garage and found the low beam bulbs are fine. Checked all the fuses they are fine. *tr
