Bought a 2003 Mazda 6 last year, my tachometer kept going crazy and the car would die out. I took it to good year, 3 codes came up. They changed the cam shaft sensor and the egr valve. That didn't fix the problem, good year took the parts out, put mine back in and told me to take it to a Mazda dealership. I took it to Mazda, they told me I had to change my pcm because it was shorting out, and my egr valve and that should take care of the problem. They quoted me 2k dollars for everything. I asked them how much they were charging for the parts, they told me 1100 for the pcm and 200 for the egr, the rest was labor. As the service advisor quoted me prices, I told her I can buy a pcm online for 145. She said, yes, you can do that, but we won't warranty the job because it's not our part. I told them are you sure that will take care of the problem? they said yes. I told them okay fine! constantly calling the dealership for 2 weeks asking when I was going to get my car back, they gave me a loaner. I had that for a week, so they had my car a total of 3 weeks. Finally I called again, I asked them what's going on with my car. They told me, I need a new engine. I was like what? what happened to 2k will take care of the problem? they said no, there's too much sludge in the engine, you need a new one. Upset, I'm already in for 2k and now they want me to spend another 5k for a new engine. Mind you, I was already hesitant because of the price of the pcm. Any way, service advisor tells me, I can buy a new/used engine online for 500 and have them change it. I told them that was the whole reason, I didn't buy the pcm online!I was told you wouldn't warranty it, now you want me to buy one online? I went to the dealership, picked up my car, still the same problem. I'm not the only one,see link . . . Read more...
