I have a 2007 Mazda 3 grand touring hatchback 5 speed manual transmission. Engine blew at 88k miles, no warning blew a piston out down through the oil pan. Being that the car was in such good shape otherwise, I initially wanted to put a new motor in. However after extensive research, I had found copious complaints of premature engine failure and an attempted class action against mazda because of this crappy motor. Owners were reporting failures at 80-100k miles. So I let it sit for 3 or 4 years because I didn't see the point in replacing the motor with the same faulty one. I found a guy that succesfully replaced his faulty Mazda motor with a ford fusion motor. The block was the same just needed to keep (or in my case get another) original Mazda 3 oil pan. The transmission bolted slightly different but other than that worked perfect. That engine is going strong 2015 until the present. However, now everything EXCEPT the motor is crappy. I don't know how much of this potentially may have to do with it sitting for so long. I love my Mazda 3 and is proving hard to part with even considering this list of problems I am about to detail below. I had issues with the shocks and struts and the large 18" rims and low profile tires made my car ride like a brick. My wheels bent and I am assuming the shot shocks caused this and I think potentially knocked some other things loose. The antenna fin may have become loose anf I beleive this caused the flood in the spare tire trunk compartment everytime it rained. The Windows gears are starting to malfunction, again. I had to replace the gas float in the gas tank under the back seats which now makes knowing when I am almost out of gas a problem. The cat is out or going out, I think is the problem as I have a weird compression that happens and makes a sputtering sound every time I fill up. I had to clean and replace the maf sensor as it use to have a hard time cranking. I think their is an electrical issue going on because last February my gauges all lit up and never went off (airbag, oil, traction and of course engine light). Mine has a bucket list of issues. Having worked on It so much, It is a love hate relationship. Oh and my a.c. belt just broke in November which I replaced but now the a.c. still is not working. The paint is and has been peeling for about 2 years and is starting to rust. But hey the one you are looking at may be swell!

Hi. First off thank you Scotty for helping me out. Just a quick follow up question : What’s the highest mileage that you have seen on those Mazdas?
