You must be dealing with some real Canadian shysters. I've NEVER had and problem getting any warranty work done.
they use a computer to determine whether it meets the threshold and the threshold is too high. this is toyota but mazda parts. went to a bunch of different dealers. one of the mechanics even said whats wrong. problem first happened back in 2020 and anyways my car is at 90,000 km now and it keeps chugging along and besides the time i wasted trying to get them to fix it, it didnt cost me anything. im selling the car next year anyways when i move to europe.
