Service department trying to scam people out of money. Brought my mazda 3 in for the service bulletin that Mazda issued to fix headlights flashing while decelerating. I later received a call that it was fixed and they were only going to charge me a half hour 75$ shop time for tightening battery terminals They claimed were loose and the cause for the lights flashing only while decelerating... really ? Only when I decelerate? And I replaced the battery and personally tightened the clamps.
Customers Beware!! It Reminds me of why I drove all the way to Portland to buy my mazda in the first place after visiting this one.
