I have a 2017 Lexus CT200h and I frequently visit the drive thru car wash and I have to put my car in neutral to go through the car wash. I've been doing this for the past year or so. Today I got the low battery warning message, I can't recall now exactly what the message said but the yellow warning light started flashing and bell was dinging while i was in the middle of the car wash. When I came out of car wash I immediately put my car in drive and left. From skimming through the posted messages it appears that putting my car in neutral is damaging my car. Should I stay away from drive through car washes?
