My Q50S is totally dead except for flashing strobes.

What is your question?

My 2019 Q50S had been running perfectly when I parked in my driveway. Came out 2 hours later and all the windows were down and the moonroof was open. Turned on power without starting engine and closed windows and moonroof. Two hours later my car was totally dead, except for flashing strobe lights at all corners. This had happened once before and car was towed to dealer 55 miles away (it is a lease). Tow truck jumped battery and car started. The next day the dealer called and said he could not duplicate the problem. I am not qualified to jump the battery, but I did disconnect the negative cable and the flashing stopped. This is Saturday night and I will wait to call my dealer on Monday. Any ideas? Thank you.

What makes this problem better or worse?

Nothing. All electrical systems dead except for flashing corner strobes.

How long has your 2019 INFINITI Q50 had this problem?

Second time in about 3 months

Hello, your dealership is the place for diagnostics and repair. No one here can really do better. All the windows open indicates the "global open" feature was tripped on the remote by pressing unlock once then holding it down. It likely happened without you knowing it, for example with some kind of unknown pressure on the remote. This happens. I witness it often with my clients. The "strobe lights" indicate the anti-theft system was engaged for some reason, and the battery is likely too dead to sound the horn any longer. The only possible additional thought is that there could be some kind of aftermarket device - alarm - in the vehicle tapped into where it shouldn't be or malfunctioning. Have that assessed. Good luck.
