Purchased a 2016 Mazda CX-3 in Sep 2015. I took it to an out of town dealer 3 days after purchase because the TPMS light came on while I was on the highway on the trip. They checked the tire pressure and it was fine so they reset it, said it probably just didn't get hard reset after the factory inspection and showed us how to reset it. It continued to come on through the winter. By the spring, I decided it was a problem and took it to the dealer. They reset it. It came back on. They reset it again. It came back on. This has repeatedly happened. They replaced the tires; it came back on. MNAO isn't responding to the dealer or to me with a fix beyond telling me to reset it 3 times from home (since the dealer resets didn't work) after the light comes on so the car will adapt to my normal driving conditions. I'm not a car engineer or mechanic but this doesn't really make sense to me. Can anyone explain this logic? Why can't I take the car on the highway for 100 miles without the light coming on? Anyone else having this problem? Thanks!
