Took the 3 in for it's 1st oil change and an issue with the rear defogger not staying on. Turned out the body control module was bad and was replaced. 1st issue I've had with any mazda I've owned. The P5 and the Miata never had any warranty claims. Apparently this is a common issue with the 3's??
Another item of notice while reading the manual is that Canadian 3's, not sure what other models this applies to, you can turn the DRL's off. I had noticed that this was the case with Mary's 3 which is great since I hate DRL's for many reasons. I was worried that the DRL's would come back on after the Body Module change since this is one of the things it controls but they have stayed off. Only the dealer can make this change.
