There is a bearing in the crankshaft that looks like it-??s not up to spec. No warning lights came on, car suddenly lost power on the highway. Fortunately no one was injured though it was a very scary situation. Mechanic took a look inside the engine and said a main bearing stud broke off and busted a hole through the short block. He said I-??m lucky the engine didn-??t turn into a grenade. Upon looking up the failure many other people have had the same issue with this engine. The exact same failure on the exact same bolt. Here are some links to some posts: [XXX] [XXX] [XXX] [XXX] Clearly I-??m not the only one with this issue, and there are more examples of the same problem that you can find online through out different Mazda models that use the same engine. I can definitely have the vehicle inspected if needed, my mechanic took video of the damage as well. I could only imagine if this happened while there was more traffic on the road, it-??s not safe. And the fact I can find more examples means there are probably more that never posted or reported the issue. the vehicle has less than 100k miles which a lot of the examples have the same issue at less than 100k INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

My car has been showing red check engine light randomly for the lst 3 months. It lasts 24 - 48 hrs, sometimes after oil change. Dealer said nothing to worry about, but I finally took it to autozone who said code was stored as misfire on cylinder 4. dealer is looking at it now, but always dismissed it before. Now that I know it has to due with a cylinder - why didn't they investigate further? of course my car is about 2 months out of warranty and 17oo miles as of today.

This car has serious problems. I have approached Mazda with numerous service complaints and they refuse to fix. The car gets terrible gas mileage not the factory stated 42 mpg which was sold on the msrp but more like 22. The suspension drives terrible makes noises, the car "creaks" when going over things and is not stable at freeway speeds. The car also sways form left to right on the freeway and is extremely slow to stop. It is dangerous and Mazda will not fix. I even have a voicemail form Mazda corporate stating then refuse to fix these problems. I have had to hired a lawyer to declare the car a lemon. Mazda also refused to service the car for oil changes, tire rotation, etc. I have also filed a claim with Mazda corporate along with the numerous times in and out of the shop yet they still refuse and are unwilling to service/fix the safety issues on my car. Also, the heated seats, both front and passenger, have not been able to be fixed since the day I purchased the car (I have now had the car approx 14 months). As of today 7/11/2017, this problem that has been going on since I bought the car early 2016 has not been resolved. Please help!
