The 12V auxiliary battery failed around 6:45pm PST on Aug. 8, 2021, causing the car to be unresponsive - Tesla acknowledged this. There was no warning prior to the battery failure. The driver (my wife) was trapped in the car because the electronic door latch would not open and the windows would not retract. My wife was panicked, crying and kicking at the window. I had to break the window to get her out. Tesla replaced the 12V battery as an item under warranty. They believe that I/we should have know about the manual door release to avoid breaking the window. This manual release is unmarked and inconspicuous. Tesla claims that the manual door release is described in the car's user manual; however, the car's user manual is electronic (no hard copy provided) and was not accessible because the car was unresponsive. The user manual can only be accessed from the car's display screen. There is no telephone number to call a Tesla representative and no way to access the user manual via the iPhone application. I had no choice but to break the window. Tesla is aware that their 12V batteries are failing prematurely and are not doing anything to prevent drivers from being trapped inside vehicles. The tow truck driver said he picked up four Tesla cars on Aug 9th for the same battery issue. I spoke to multiple other Tesla owners and none were aware of the manual door release. This includes one of my neighbors who received his Tesla a few months ago. It was not explained duri
