Driver-controlled interior lights: no issue for me. My 2012 GT has two overhead switches that actuate the two overhead lights in the front compartment. In a bind, I can (barely) reach the switch to turn on the rear overhead light, but why would I when the rear seat occupants could do so more easily.
Some of my gripes after 2500 miles:
- Power - It's awfully weak for a modern 2.5L. How about at least a "mild" turbo, like Volkswagen's 200-hp 2.0L?
- Fuel Economy - Again, for a modern engine in 2012 the real world mileage is poor. I got about 24 mpg on a 650-mile trip and get 15-16 mpg around town.
- Sun visors - Not only are they terribly cheap, but they have no 'extenders' to block out the sun through the side windows.
- Dash Storage - Although the 5 has plenty of small storage enclosures built into the dash, they're all made of hard plastic. MP3 players, sunglasses, change, etc. will rattle your brain, plus will slide onto the floor at the first sharp turn. Gimme a grippy, rubberized surface!
- Door Sills - the inside of the upper doors is lined with some type of fabric. It looks great new, but I happen to lean my elbow on the sill when I drive and the fabric is already starting to show wear.
- Power Outlet - The power outlet shuts down when the engine is off. Some people like this - - I don't.
- HomeLink - I'm very disappointed Mazda chose not to include HomeLink in the top-of-the-line GT. Now I must keep a clunky garage opener in my car.
- Audio 'Beep' - Even though I have selected "No Beep" in the audio system, it continues to register a 'beep' whenever I increase or decrease the volume using the steering wheel control. Idiots!
- Floor Mats - The quality of the floor mats (as well as the cargo area carpet) is REALLY cheap. The grippy rubber soles of my casual shoes were taking chunks out of the driver mat, so I had to stop wearing my favorite shoes! Even my previous CX-9 GT had this quality problem. My right heel wore a hole through the mat in less than two years.
Other than these mostly niggling issues, I LOVE my 5!
