Hi All, The other day, for the first since I owned my 2018 Frontier, a red light flashes it has the vehicle with a Key inside. When the engine is off, blinks every 30 seconds or so. It never did this before. The manual does not give me any answers on if there is a problem. The manual identifies it as the security indicator light, but it does not turn off? I have to think in the last 3 years I would notice it. It started to blink out of the blue. Any thoughts?
