Since i purchased this vehicle the headlights dim way down and sometimes change intensity greatly every single time the a/c compressor clutch engages and draws current. all lighting across every system in the vehicle dims way down as well. that is, interior illumination, instrument console and panel, exterior marker lights. all lighting dims when the compressor clutch engages. the local dealership has tried a few things as instructed by the manufacturer but the situation has not been corrected. while out on freeways at night following behind other vehicles, the driver will become annoyed in front thinking that i am purposefully flickering or flashing the headlights to encourage them to speed up or move out of the way. this can cause a dangerous situation. this situation has been present since the vehicle was purchased in november 2018 and remains.
