Good luck. Mazda wouldn’t ride with me for the past 25k miles I tried to get them to solve a front end rattle. They continued to tell me to come back when it’s worse. It continued to get worse, I came back every 3-6 months, complained, left it with a full tank and permission to drive it like their own, to lunch, home for the night, whatever it took. I got it back with no more than 10 miles on it at a time, no problem found, and refusal to come to exactly where (in the same county and zip code) I can make it make the noise every time. Mazda USA and the dealer told me they’d solve it one day under warranty or good will. As soon as I went out of 3/36 warranty, new management came into my dealer and Mazda USA won’t stand behind it anymore either.
So moral of the story, good luck! I worked at a dealer for 11-12 years as a tech. I understand some things suck to deal with when you’re flat rate, but it’s part of the job.
