In owners' own words
Vehicle developed burning oil smell. Dealership diagnosed a cracked cylinder head. No warning lights (yet. Eventually low oil pressure light would come on.) Potential for engine to lock up and lose power while driving putting occupants and others at risk. Know problem for 2018-2021 model years. Car no longer under warranty. Cost to repair $7,100. Technical Service Bulletin SA-031-21 issued regarding this problem. Engine
Cracked cylinder causes oil leak in 2018 Mazda CX-5. May occur in other model year CX-5 as well. Issue was inspected by an authorized dealer. Repair by Mazda not performed because vehicle was a few months past warranty expiration date. Issue with CX-5 cylinder-head are shown below: [XXX] [XXX] [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6) Engine
Oil started to leak along with a burning smell, ended up being a cracked cylinder head at 77k miles. It was not in an accident & it did not overheat. But it appears this is a known issue with this make, model & year. Now Mazda only wants to pay $1k of $5k charge. I bought the dealers extended warranty, up to 75k miles, which apparently means nothing. My next car will not be Mazda. Engine
