where are you located?

 

When my cat was overheating it was glowing red around the O2 sensor on the drivers side you could drive it and take a photo if it gets like that. The dealership have to inform Mazda of the problem and then Mazda decides if they will pay the bill for them. That is extra work for them and they don't get extra money so they will always try to charge you cash first. I would tell then you re not willing to pay another $85 when they didn't do it correctly last time. (You will need to work on your pitch, be annoyed and loud in the showroom but don't overdo it so you get thrown out)>

 

I'm in Southeast Missouri...about an hour and a half from St. Louis.


I'll try that...Thanks...He said I'm definitely under warranty until April of 2012...I just hope I can prove to them someway what its been doing before its too late...

 

was the light on when you took it to the dealer?
I would wait till the light is on then take it to the dealer.
but seriously, this topic has been discussed many times.
