I have a 2012 Kia Optima Hybrid - 107k miles. Recently I've notice a burning smell and smoke coming from behind the driver's side headlight (below the coolant filler reservoir) once the engine comes to temp. All gauges are normal, engine temp is normal. May be electrical. Smoke/smell dissipates as soon as the car is off (maybe lingers for 20-30 seconds). Any thoughts? I've been reading a lot about issues with engine/electrical fires. Thank you in advance.
