High beams stopped working all of a sudden, but the vehicle thinks they are on because when I turn the switch to the high beams setting the fog lights turn off, and there is a small flicker that seems to be indicating some kind of short in the wiring. The vehicle was purchased with after market LED high beams already installed, but despite switching the headlamp assembly the high beams still did not turn on so the bulb is not the issue. Taking it into the dealership since my extended warranty should cover it.
