I just bought a Toyota Corolla 2013 Special Edition last week. Just after a few days, suddenly once I entered the key, turned and I was going to start the engine, everything started blinking, the monitor, and the security light, making flasher sound as if I turned flashers on. I then just drove, and suddenly a bit further while I was driving, it started honking by itself, looked like something makes it think I am robbing the car. After a while, the alarm randomly went off sometimes when I was pushing the lock button on the key fob, like someone pressing the panic button on my fob.
After a few starts and engine not starting, the battery also died. I went to the dealership, and they replaced the battery and said this should probably remove the problem.
What is the problem? Was it really because of a dying battery?! Should I expect the battery replacement fix the problem?
