My neighbor's Sienna (newest model) had the stop light burned out several times.
There is no warning on Toyota, so I notified him several times. He said he replaced them several times already, and they keep going out.
Apparently, such thing is not unique to Mazda.
My old '98 BMW 540iA had the tail light out so many times that I lost count.
There was a warning display on BMW, so I got notified frequently. I actually stocked up several
bulbs inside the glove compartment. That tells you how often it failed.
It seems that nowadays the light bulb quality is not as good as they used to be...
Especially, the ones you can buy from Autozone and Kragen. They are so easy to get burned out.
I found that once you have to replace the OE ones, the new ones from Autozone/Kragen don't last as long...
