Consumer Description

Noticed the smell of burning oil and smoke from the engine while driving on the interstate with my husband and young children in the vehicle. Pulled over at a gas station to inspect and discovered large amounts of oil leaking. While at the gas station the low oil indicator came on. There were no warning or check engine lights prior to the incident. The dealership diagnosed cracked cylinder head. This was an extensive and costly repair. I have now learned that Mazda is aware of how common this issue is with this year/make/model. This should be a covered repair or recalled part.
