I got my 3i GT hb about 72 hours ago. It replaced a 2013 Ford Fusion SE. A few things immediately come to mind.
All 4 windows should retain power until the door is opened, not just the driver's window.
I wish they all did as well. On the Gen1s (mine) none of them do. There are some electrical mods that can be done to fix this, but I never bothered.
The doors should automatically lock when the car is put in gear.
Disagree - this is the most annoying feature ever and I love that Mazda didn't include it.
The fancy radio should have more storage options for favorites, not just one gigantic pool. The Fusion had 3 sets of 10 stations each.
Never needed more than 5, so I can't relate but my gf did have a GM that had the same sort of radio that you're talking about. It was handy for storing favorites in multiple cities, but everything else about that radio sucked, I much preferred the Mazda solution. Can't speak for the Gen3s radio though, never tried it.
The fancy radio should display the entire name of the performer and the entire name of the song or programmer, scrolling if necessary, rather than only displaying text on the left half of the screen.
This feature has been lacking since day 1. I just stopped caring.
If you care a lot, you could look into an aftermarket audio solution as many people do.
The light in the hatch area should be on a switch so when you open the hatch it turns on and closing the hatch turns it off. It wouldn't be difficult to run the battery down with it like it is.
It has done that (auto switch off) in every year that I know of. Are you sure you're not doing something wrong?
