My wife has a 2015 BM Mazda 3 Touring automatic we bought new June 2015. It has done 130,000km faultlessly but one morning wouldn't start - nothing happened when she pressed the button. She called theRACV and the guy disconnected the battery for a few minutes and it came good - temporarily of course - first thing to try on modern cars. Sort of a reboot. Next morning same problem but different RACV guy noticed her brake lights weren't working and diagnosed brake pedal switch failure.

The two local Mazda dealers couldn't do it for 2 days so she used a local guy I've used for performance work on my car (basically specialises in GM/HSV). He fitted a new switch but then told her she needed to go to Mazda to have something calibrated???

Does that sound correct? Everything I read suggests it's just a simple replace switch and go? I don't have any problems with her taking it back to the dealer we bought it from and have supported by having all services done there (expensive) but they quoted something like $250 just to look at it! 😯😯😯

Does it really need something calibrated with their scanner? Probably maximum 10 mins if so..... 😭

Hmmm. My wife took it into her Mazda dealer this morning and suffice to say I was pleasantly surprised that she was only charged about half what she'd been told on the phone and found that the switch had been incorrectly fitted, apparently not uncommon. I had found a video on fitting and it would seem to fully position it, it needs a final little rotation to lock it in place so I guess that's what he forgot. Fingers crossed it's now good, otherwise requires another brake switch ($90 list!).

Seems he was guessing about needing calibration - apparently not required.
