I had the most bizzare experience at a dealer here in the Toronto area today.
My car ('19 signature) started exhibiting this issue on the passenger side initially, and then the drivers side just over the past few months.
Took it in today, and... they claimed that they looked at the issue but couldn't find a fault, and that they had called the Mazda Tech line and were informed that there would be a TSB that would be issued in Canada sometime next year.
I alluded to the "Mazda NORTH AMERICA" TSB that is posted on this thread, and he said that there wasn't anything in their system.
Has anyone in Canada had this issue and then had it repaired?
I should mention - they never fixed it.
