What owners say about the electrical system

Verbatim from NHTSA complaints, newest first
“The car's electrical system doesn't fully turn off after being put in park and turning the ignition off. The electrical system stays on, despite the engine and ignition turned off. It's a BIG problem that I've seen a lot of other people report. And yet Mazda refuses to address the issue.”

“We have had numerous times that the vehicle ignition system will not turn off after pushing the stop button. The motor will stop but the ignition and radio system stay on. The car must be restarted(sometimes numerous times) and shut down before the ignition system shuts down. I have seen many other owner's complaints about this same problem on (carcomplaints .com).”
