This car has a confirmed cracked cylinder head and is leaking oil. This is a known issue and there is a TSB out for it. It happened at $62500 miles and is just outside of the warranty. This has happened to several of these cars. Mazda is not doing "good will" to repair them and there is not yet a recall which there should be. The car suddenly started leaking oil and smoking/burning. It is unsafe and a defective cylinder head. Mazda should be taking responsibility for this
Cracked cylinder head. Burning oil smell. Coolant leaking into oil. Car purchased a year ago for $21,500. Dealer I bought it from paid 1/2 after sending it out to Mazda to be diagnosed and fixed.
Oil leak. Smoke from the engine. Inspected by the local body shop, we were told that the leakage would probably come from cylinder head. [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
