Horn goes off whenever it wants....no time or day to predict when it will happen...no difference if the car is locked or unlocked...just wonder if this a problem Mazda will ignore like the rusted frame that almost got me killed when it fell apart while on the road...Mazda told me it was because I live in PA and the weather here is bad in the winter...what a joke....they finally had to admit it was a recall after months of fighting with them

this may be the same situation but I know I'm definitely not paying $110 to have it diagnosed...they told me the codes were changed when I got a new battery but it didn't help....will never buy a Mazda again

I have this 2006 Mazda 6 and its nothing but a thorn in my side. Besides all the recalls it has, I have to deal with running to the window at least a dozen times a day. I have to sit my key beside me at all times because I never know when my car alarm is going to go off and I have to stop what I'm doing and run to the window and stop the alarm, and try not to bother my neighbors too bad with hearing a car alarm all hours of the day and night. It is embarrassing. I put a new battery in it hoping that would work but it didn't. I go check all the doors all the time but nothing I try works. I have had all the doors tightened but it doesn't matter, that alarm still goes off just whenever it wants to... Now I know why my whole family only buys America made...... They have never had as much trouble as I have with this Mazda, with every vehicle they ever owned put together!!
