Jun 2018 90000 mi	No parts have been replaced yet but at 90k miles the automatic transmission has started slipping when it shifts from 3rd to 4th. Only does it on the first shift on a cold engine so I'm going to try and milk it for a while. Also when I changed the spark plugs, cylinder 1 had oil on the plug so a seal is failing in the head. The car is driven 80 miles on the interstate everyday so I did not expect any major problems for another couple years. Very disappointing. Now I see why people buy boring Camry's. This is my first Mazda. Changed spark plugs at 90k miles. I noticed that cylinder number 1 had oil on the threads and the tip of the spark plug which would indicate a seal failure in the engine.
