After getting 100k service done, I realised the car was getting flat spots in power. Was worried, but Mazda said I have to wait for next appointment which was 3 days.
Couldn't wait that long, so took it to a local mechanic to get a quick check up.
FOUND 3 HOSES NOT TIGHTENED BACK UP, SO THE ENGINE WAS LOSING PRESSURE.
The apprentice must have forgotten to tighten them, oops it happens. No it shouldn't happen when you pay $700.
Mazda should've told me to come back immediately for safety reason.
Never going back again.
