Went out this morning, and my 25 ST was dead. Dead-Dead. Had to use the physical key to open it. Tried jump starting it, to no avail. Called roadside assistance, who got it started with a stronger jump-box. Said my battery was down to 5 volts. Only 4,600 miles on it. Always happens on a weekend. Things were acting strange over the past week. I keep my lane assist turned off, but it turned itself on, and my easy exit turned itself off as well. All this after the latest OTA update. Goes to the dealer on Monday. Anybody else experience stuff like this?
