“2005 Mazda 3 with 30k miles. About a month ago the car started hesitating while driving and then stalling when stopped. The check engine light came on. Brought it to the dealer and they indicated it was the oxygen sensor, which they replaced later in the week. It's been three days now and I'm experiencing the same problem. Check engine light came on again. I'll give dealer one more chance to diagnose and fix the problem or I'll try someone else.”

“2005 Mazda 3 air compressor goes out, lines fry under hood after doing some research on the issue on the internet, I found that many individuals are having the same issue under 60,000 miles and the A/C never works to maximum output. Contacted Mazda and while they say they are aware of the problem, no recall has been proposed, therefore I was redirected to this site. Contacted Mazda over a year ago under the advice of 2 mechanics who insisted this incident should not happen to such a young car. …”

“2005 Mazda 3s with only 39k miles broke down with heavy smoke, near fire, fortunately at dia airport. Towed to local denver Mazda dealer, who diagnosed a seized A/C compressor. Contacted Mazda national customer care, who covered the $1k cost of the new compressor, with me picking up the labor. Out of warranty, barely; this kind of thing should not happen for a young vehicle, original owner, with pampered preventative mnx per schedule. I do appreciate the fact Mazda stepped up to compensate a majority of the repair cost. …”
