I can help: I advise you to read in the Tech Garage / Issues & Problems sub-forum. Don't worry about new posts or current discussions - read back through the old ones. The 2004s have been around quite a while so they've been discussed backwards and forwards from every angle multiple times. You don't even need to search, just bring up the forum and start reading threads with interesting subject lines.

You should also read all the STICKY threads at the top of each sub-forum.

Doing those two things will likely answer most questions you might have. Some people do that reading before they join as a member or make their first post, but that's just some people.

.....and welcome to the forum.

 

I initially thought the same thing, "avoid the first model year to avoid start-up bugs." However, I bought a 2004 and really can't complain. If you buy a used 2004 the previous owner should have gotten the applicable Technical Service Bulletins applied. If you buy a used 2004 or early 2005 model you should see if the vehicle has already gotten the upgraded starter motor and new spark plugs to address the "Hard Start" issue.

However, keep in mind, those TSBs are not all bad. My 2004 demonstrated brake squeal so Mazda replaced my brake pads at 10,000 miles. So, when will I need to pay my own money for replacement brake pads? Later than otherwise.

Sometime in the 50,000 mile warrenty I may get the upgraded starter motor and hotter plugs. Hmmm, that means replacing the original components with a brand new ones free of charge. Since I plan to keep the car for many years and well more than 100,000 miles it would be a bonus to have certain parts replaced after 20,000, 30,000 or 40,000 miles.

 

I prefer to think of it as getting everything that's coming to me. Thanks - I do my best.
