| Exterior Lighting problems |
Exterior and interior lighting on brand new Yaris randomly malfunction while driving. This has been an ongoing problem but Toyota can't find the source of the problem so nothing has been done about it.
All exterior and interior lights turn off on their own. They have done this twice. This is a brand new car that my 18 year old son bought. He drives to college and work and cannot be driving a vehicle that has lights that do not work in the dark. The dealership has looked at the car but cannot find the problem so they are asking us to come back and pick it up. I refuse to let anyone drive this vehicle until it is safe to drive. My son pulled over in each instance and turned the car off and back on and played with the light switch off and on and the lights did come back on. I seems to happen sporadically.
